    <title>Abstract</title><sec>
    <title>Background</title>
    Enhancing empathy in healthcare education is a critical component in the development of a relationship between healthcare professionals and patients that would ensure better patient care; improved patient satisfaction, adherence to treatment, patients’ medication self-efficacy, improved treatment outcomes, and reduced patient anxiety. Unfortunately, however, the decline of empathy among students has been frequently reported. It is especially common when the curriculum transitions to a clinical setting. However, some studies have questioned the significance and frequency of this decline. Thus, the purpose of this study was to determine the impact of postgraduate clinical training on dental trainees’ empathy from cognitive, behavioral, and patients’ perspective.


    </sec><sec>
    <title>Methods</title>
    This study included 64 trainee dentists at Okayama University Hospital and 13 simulated patients (SPs). The trainee dentists carried out initial medical interviews with SPs twice, at the beginning and the end of their clinical training. The trainees completed the Japanese version of the Jefferson Scale of Empathy for health professionals just before each medical interview. The SPs evaluated the trainees’ communication using an assessment questionnaire immediately after the medical interviews. The videotaped dialogue from the medical interviews was analyzed using the Roter Interaction Analysis System.


    </sec><sec>
    <title>Results</title>
    No significant difference was found in the self-reported empathy score of trainees at the beginning and the end of the clinical training (107.73 [range, 85–134] vs. 108.34 [range, 69–138]; <italic>p</italic> = 0.643). Considering the results according to gender, male scored 104.06 (range, 88–118) vs. 101.06 (range, 71–122; <italic>p</italic> = 0.283) and female 109.17 (range, 85–134) vs. 111.20 (range, 69–138; <italic>p</italic> = 0.170). Similarly, there was no difference in the SPs’ evaluation of trainees’ communication (10.73 vs. 10.38, <italic>p</italic> = 0.434). Communication behavior in the emotional responsiveness category for trainees in the beginning was significantly higher than that at the end (2.47 vs. 1.14, <italic>p</italic> = 0.000).


    </sec><sec>
    <title>Conclusions</title>
    Overall, a one-year postgraduate dental training program neither reduced nor increased trainee dentists’ empathy levels. Providing regular education support in this area may help trainees foster their empathy.

    今回,終末期の患者に対して約2年半に渡って総合的に歯科医療を提供した。症例は74歳男性である。岡山大学病院に口腔衛生管理のため総合歯科受診し,肺がん既往のため同呼吸器外科にも長年通院していた。2017年4月から肺がん再発に伴い口腔内感染源除去,咀嚼機能の回復を行うとともに化学療法に向けた口腔衛生管理や指導を行った。しかし化学療法の副反応として間質性肺疾患が発症したことを契機に,患者との共同意思決定により緩和ケアへと移行し,骨吸収抑制薬関連顎骨壊死予防のための口腔衛生管理を行った。その後のアドバンス・ケア・プランニングによりQuality of life(QOL)の維持と延命治療の拒否を希望したため,点滴に頼らず水分栄養を経口摂取するための口腔機能の維持管理を目的に治療を継続した。その後骨吸収抑制薬関連顎骨壊死発症に伴い抜歯を行い,義歯新製を行いつつ逝去の1ヵ月前まで通院が継続し,その間口腔機能を維持できた。また,全身状態の悪化により他院緩和ケア病棟に入院した後も,完成義歯を持参して見舞うなど患者に寄り添うことができた。アドバンス・ケア・プランニングにより患者の希望に寄り添いつつ前向きな歯科治療を提供することで,患者および家族の満足度の向上に寄与した。研修歯科医の当初から比較的長期に治療を継続することでターミナルケアにおける歯科治療の意義を強く意識するようになった症例であった。(著者抄録)

    OBJECTIVES: We aimed to clarify the communication behaviors between trainee dentists and simulated patients (SPs), to examine how the level of trainee dentists' self-reported empathy influences assessment by SPs in medical interviews. MATERIALS AND METHODS: The study involved 100 trainee dentists at Okayama University Hospital and eight SPs. The trainee dentists conducted initial interviews with the SPs after completing the Japanese version of the Jefferson Scale of Empathy (JSE). All interviews were recorded and analyzed using the Roter Interaction Analysis System (RIAS). The SPs assessed the trainees' communication immediately after each interview. The trainee dentists were classified into two groups (more positive and less positive) according to SP assessment scores. RESULTS: Compared with less-positive trainees, the more-positive trainees scored higher in the RIAS category of emotional expression and lower in the medical data gathering category. There was no difference in dental data gathering between the two groups. SP ratings for more-positive trainees were higher for use of positive talk and emotional expression and lower for giving medical information and dental information. Trainees with more positive ratings from SPs had significantly higher JSE total scores. CONCLUSION: The results of this study suggest that responding to the emotions of patients is an important behavior in dentist-patient communication, according to SPs' positive assessment in medical interviews. Further, SPs' assessment of trainees' communication was related to trainees' self-reported empathy, which indicates that an empathic attitude among dentists is a significant determinant of patient satisfaction.

    当大学病院での歯科医師臨床研修を修了した女性歯科医師188人を対象に勤務への満足度についてアンケート調査を行い、114人から有効回答が得られた。現在就労している91人のうち、70人(76.9%)が勤務に満足していた。経験年数(1〜4年、5年以上)、認定医もしくは専門医の有無、勤務形態(常勤、非常勤)、開業の有無(開業、勤務)、勤務場所(診療所、病院もしくは大学病院)、休職経験の有無、結婚の有無、配偶者の職業(歯科医師、以下医師以外)、子供の有無と勤務への満足度との関係を検討したところ、勤務形態においてのみ常勤は非常勤に比べ満足度が高い傾向があった。勤務に満足している理由は「やりがいがある」、「上司や同僚の理解がある」が多く、勤務に不満足な理由は「家庭と勤務の両立が難しい」、「プライベートの時間がない」、「男性主導社会」が多かった。常勤では満足の理由・不満足の理由ともに&quot;上司の理解&quot;であり、非常勤ではいずれも&quot;家庭と仕事の両立&quot;で、非常勤においてのみ「収入が悪い」「勉強時間がない」も不満足の理由として挙げられていた。以上より、女性歯科医師の勤務への満足度は勤務形態に左右されると考えられた。

    我々は,女性歯科医師のキャリア形成やライフプランに影響を与える要因を検討する目的で,平成18〜24年度に岡山大学病院で歯科医師臨床研修を行った女性歯科医師188人を対象にアンケート調査を行った。そのうち,本稿では女性歯科医師が考える「理想の歯科医師像」について,テキストマイニングソフトを用い,分析した。回答者の理想の歯科医師像は,歯科治療の技術や患者との関係性のみではなく自身の環境に触れたものが多かった。全体で最も出現頻度が高いキーワードは「歯科医師」であり,以下「仕事」,「家庭」,「患者」,「両立」などとなった。分析結果から,女性歯科医師が考える理想の歯科医師像はワークライフバランスを重視していることが伺え,そのバランスの割合や重んじる部分は結婚,子供,就労,休職経験の有無といった状況によって異なると考えられた。女性のライフコースが多様化している現在,どの時期にライフイベントを行うことになっても,仕事との両立ができるようなサポート体制の整備や,男性歯科医師を含むすべての就労者にとって家族のことを考えやすい環境を整備することが大切である。(著者抄録)

    本論文では臨床実習を終了した6年次生が、自身が1年次に受講したエスコート実習をどのように評価しているかを実習直後の評価と比較、検討した。1年次に実施された患者エスコート実習に対するアンケートは同一学生に2回実施された。1回目は1年次のエスコート実習直後に、そして2回目は5年経過後の臨床実習終了時に1年次に受講したエスコート実習を振り返り、アンケートに回答した。その両方に回答した82名を対象者とした。1回目と2回目の評価を比較、分析した結果、以下の結論を得た。臨床実習終了時のエスコート実習に対する評価は、1年次の実習直後の評価と比較して有意に低下した。エスコート実習直後にはエスコート実習を肯定的に評価していたが、臨床実習終了時にはその評価が否定的に変化した学生は、患者の視点の理解や医療人にふさわしいコミュニケーションの技能の理解の観点からその評価が低下していることが明らかになった。一方、エスコート実習直後と臨床実習終了時の両方においてエスコート実習を肯定的に評価した学生においては、医療人にふさわしいコミュニケーションの技能の理解の観点からエスコート実習が有意義であると評価していることが示された。以上より、学生はエスコート実習直後のほうが5年後の臨床実習終了時と比較してより肯定的にエスコート実習を評価をしていたが、一部の学生にとっては一定の価値のある実習であることが示唆された。(著者抄録)

    Anodic oxidation is used for the surface treatment of commercial implants to improve their functional properties for clinical success. Here we conducted ultrastructural and chemical investigations into the micro- and nanostructure of the anodic oxide film of a titanium implant. The anodic oxidized layer of a Ti6Al4V alloy implant was examined ultrastructurally by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). They were also analyzed using energy dispersive X-ray spectrometry (EDS) and X-ray photoelectron spectroscopy (XPS). The TEM revealed that the oxide layer of the Ti6Al4V implant prepared through anodic oxidation was separated into two layers. Al and V were not present on the top surface of the anodic oxide. This can be attributed to the biocompatibility of the anodic oxidized Ti6Al4V alloy implant, because the release of harmful metal ions such as Al and V can be suppressed by the biocompatibility.

    IntroductionSimulated patients (SPs) need education and training in required skills to be effective resources in education. This study was conducted to examine the effectiveness of an SP training programme based on the accuracy of trainee responses and the appropriateness of their feedback.
    MethodsThirty-two applicants to the training programme and 35 experienced SPs were included in this study. The experienced SPs served as a reference group. The rate of accurate responses and the rate of appropriate feedback were assessed with pre- and post-training tests, and these two outcome measures were compared with those of the experienced SPs.
    ResultsNo significant differences were found in trainee response accuracy or appropriateness of feedback between pre- and post-training tests. The response accuracy rate of the trainees on the pre-training test was significantly lower than that of SPs with 1-2years of experience, whilst there was no significant difference between these SPs and the trainees on the post-training test.
    ConclusionsAlthough our study suggests that more training is needed to improve the skills of SPs, the training programme may contribute to helping trainees reach a novice level in the skill of providing accurate responses. SP training should be encouraged to contribute to the effectiveness of such teaching and to establish the validity of the assessment.

    過去5年間に岡山大学歯科医師卒後臨床研修プログラムを選択した研修歯科医師280名を対象に、研修開始時と終了時に30項目の臨床経験の有無についてアンケート調査を行った。その結果、概ね経験できている項目は研修開始時6項目、終了時16項目であった。経験者率は終了時の方がほぼ全項目で高く、23項目は有意に高かった。単独型プログラムと複合型プログラムの終了時の経験者率の比較では、単独型プログラムの方が高かったのは1項目、複合型の方が高かったのは4項目であった。岡山大学出身者と他大学出身者との比較では、研修開始時、終了時共に岡山大学出身者の方が経験者率が高かった。以上より、研修開始時は研修歯科医の臨床経験の差が大きく、臨床研修終了時には全ての検討項目で経験率が上昇した。卒前教育での経験の差は卒後臨床経験に影響することが示唆され、卒前教育と卒後臨床経験の連携の重要性が再認識された。

    One of the prominent roles of the occlusion would be to support the force balance wobbling in stomatognathic system, thus pacing and minimizing the change of force distribution with age. Patient's demands on the prosthetic treatment have been becoming higher and more complicated during the past several decades. These demands include not only the precise restoration of the decayed tooth but also the treatment to provide stable and comfortable state of the stomatognathic system in the longer term. These demands would deeply be related to ; 1) How to finalize the information on temporary or treatment prosthesis, which has the resulted shape of the precise functional adjustment, on the final prosthesis, and 2) How to cope with the persistent complaints regarding tooth, tongue and other related sensations. In these aspects, patient's subjectivity and/or esthesis might need to be satisfied with the form and/or function of the resulted prosthesis. The clinical difficulties might be related to the following two points, which are 1) the accuracy of the reproduction procedure from the treatment prosthesis to the final one and 2) stability of the mandibular position or the condylar position which support the functional basis for the prosthesis. In order to cope with the complicated requirements, we have been using double-casting method for providing cast restorations. This is a method to produce a cast restoration in two functional parts. The first casting step consists of a base-crown which covers the abutment tooth and adjacent proximal contact point(s). The second step is the molding of the functionally required occlusal form onto the base-crown. The third step is the metal casting onto the base-crown replacing the molded portion. This method could be applied in various situations where we are forced to match the function and the form. The purpose of this paper is to provide a good orientation to the double-casting method and also to discuss the concept that might pace and minimize the change of force distribution in stomatognathic system.

    医師・看護師等への薬剤師側からの積極的な薬剤情報提供は、チーム医療における薬剤師の重要な職務の1つである。しかし、歯科医師を対象とした薬剤情報提供の有用性に関する報告は見当たらない。そこで今回、研修歯科医を対象として、研修歯科医が必要としている薬剤に関する情報のアンケート調査を行い、この結果に基づき薬剤師側からの情報提供を行った。その結果、研修歯科医は抗生物質や鎮痛消炎剤(以下、NSAIDs)、処方せん、患者に応じた投与設計に関する情報などを必要としていることが明らかとなった。また、薬剤師側からの情報の活用度および有用度では、抗生物質やNSAIDs、処方せんの内容が有用であるという結果が得られた。これらのことから、歯科医師に対しては、よく使われる薬剤に関する情報はもとより、処方せんに関する情報も積極的に提供していくことが有用であると考えられた。(著者抄録)

    Background: Expression of argyrophilic nucleolar organizer regions (AgNOR) was counted on mucosal epithelium to detect whether the AgNOR count (the number of AgNOR per nucleus) is, for 20 weeks, affected by streptozotocin-induced diabetes mellitus.
    Methods: Diabetic rats were applied non-denture wearing, non-pressure contact, continuous pressure (0.5, 1.5 or 3.4 kPa) and intermittent pressure (10.5, 33.0 or 81.7 kPa), respectively.
    Results: In the non-denture wearing or the non-pressure contact group, AgNOR count was almost constant (ranging 1.86-1.92) without significant difference. Under continuous pressure, AgNOR count significantly decreased at earlier stage and finally recovered to the non-pressure contact group. A similar effect of continuous pressure appeared to manifest itself in intermittent pressure, but to a greater degree. Consequently, AgNOR count under intermittent pressure showed no recovery at 20-week stage.
    Conclusion: Diabetes mellitus exerted, by itself, no influence on the cellular proliferative activity under continuous pressure, whereas the activity deteriorated under intermittent pressure.

    The effect of calcium supplementation on the bone dynamics in the hard palate of the molar region (maxilla), mandible and proximal tibia in experimental osteoporotic rats was examined. Ninety ovariectomized (OVX) and 45 sham-OVX Wistar female rats were used in this study. All the rats received surgical operation at 6 weeks of age. Ovariectomized rats were fed on a low calcium diet (0.02%) for 12 weeks post-operation, and then randomly divided into the two following groups. One group was fed on high calcium diet (2.30%) (OVX-HCa) and the other group was remained on the low calcium diet (OVX-LCa). Sham-OVX rats were fed on regular calcium diet (1.15%) during the experimental period (Sham-OVX). Histomorphological analysis was carried out from 12 to 32 weeks postoperation. On undecalcified thin section, bone volume, eroded surface, osteoid surface and bone formation rate were calculated for cortical bone of the maxilla, and for cancellous bone of the mandible and proximal tibia. In the OVX-LCa group, compared with the Sham-OVX group, decrease of the bone volume and increase of the bone resorption and formation parameters were detected throughout the observation periods. In the OVX-HCa group, compared with the OVX-LCa group, increase of the bone volume and temporarily increased parameters of bone formation at I week after feeding on high calcium diet were observed in the maxilla, but these changes were not observed in the mandible and proximal tibia. Moreover, the bone resorption and formation parameters in the maxilla, mandible and proximal tibia in the OVX-HCa group became equivalent to the Sham-OVX levels with the passage of time.

    The purpose of this study was to investigate bone dynamics in denture supporting tissue under continuous pressure in the diabetic condition by using bone histomorphometry in relation to initial intensity of continuous pressure exerted through the denture base. The experimental denture base, which was designed to load initial continuous pressure of 0.0, 1.0, 10.0 or 20.0 kPa to the denture supporting tissue, was applied to the molar region of hard palate of streptozotocin-induced diabetic rats. Fluorescent labelled palatal bone tissue was stained with Villanueva bone stain and was prepared for the undecalcified grinding section. In 0.0 kPa group, no bone resorption was observed and bone formation was transiently inhibited after the denture insertion. In 1.0 kPa group, although no bone resorption was observed, the beginning of bone formation after the inhibition of bone formation was later than that in 0.0 kPa group and bone formation dynamics after the resumption of bone formation was similar to that in 0.0 kPa group. In 10.0 and 20.0 kPa groups, bone resorption was observed until 3 and 4 weeks, respectively, and the amount of bone resorption for each group was 60 +/- 16 and 87 +/- 18 mum, respectively. The resumption of bone formation in 10.0 and 20.0 kPa groups were observed at the same stage with 1.0 kPa group, and the bone formation dynamics after the resumption of bone formation in 10.0 and 20.0 kPa groups were also similar to that in 0.0 kPa group. From the results of this study, it was revealed that bone formation following bone resorption did not cause equivalent recovery of the bone surface level to the level observed in the case without bone resorption in the diabetic condition.

    The effects of ovariectomy and/or dietary calcium deficiency on bone dynamics were examined by comparing the histomorphometric changes in these bones. Five groups of rats were studied, (1) unoperated basal controls: (2) sham-operated, fed on a normal-calcium diet; (3) ovariectomized, fed on a normal-calcium diet; (4) sham-operated, fed on a calcium-deficient diet; (5) ovariectomized, fed on 3 calcium-deficient diet. The basal controls were killed at 6 weeks of ago, and the remaining groups were killed at 18 weeks of age. The hard palate. mandible and proximal tibia were processed undemineralized for quantitative bone histomorphometry. Bone volume, eroded surface, osteoid surface and bone-formation ratio were calculated. A significant age-related increase in bone volume and a significant decrease in bone formation were observed in the hard palate and mandible, whereas no significant age-related increase in bone volume could be found in the tibia. In the hard palate, ovariectomy neither inhibited age-related increases in bone volume nor affected bone dynamics, while both the combined ovariectomy and dietary calcium deficiency and dietary calcium deficiency alone led to bone loss and increased bone turnover. In contrast, in the mandible and proximal tibia, ovariectomy alone as well as dietary calcium deficiency led to bone loss and increased bone turnover. Ovariectomy, therefore, produced no significant changes in the hard palate, but affected bone dynamics in the mandible and tibia. However, dietary calcium deficiency induced bone loss and increased bone turnover in the hard palate, mandible and proximal tibia, independently of ovariectomy. (C) 2001 Elsevier Science Ltd.

    The purpose of this study was to evaluate changes in the argyrophilic nucleolar organizer region (AgNOR) counts in mucosal epithelium induced by continuous or intermittent compressive pressure exerted through experimental denture bases and to examine the relationships between the AgNOR count, histopathological changes and the intensity of the pressure under denture bases. Continuous or intermittent compressive pressure exerted through the denture bases was applied to the hard palate of the molar region in rats. A morphometric analyses of AgNORs was performed in denture-supporting tissue 3 days and 1, 2, 4, 8, 12 and 20 weeks after the denture insertion. From the results of this study, it was found that non-pressure contact of the denture bases with palatal tissues did not change the AgNOR count. The AgNOR count was decreased by continuous or intermittent compressive pressure, and then recovered to almost the same level as with the non-pressure contact at 20 weeks following a decrease of the pressure. The AgNOR counts in the epithelium under the denture bases were revealed to be related to the histopathological changes in the denture-supporting tissues and the intensity of the pressure under the denture bases.

    Osteoclastic bone resorption under the denture base has been considered to be influenced by mechanical force exerted through the denture base. However, no scientific evidence has been shown concerning whether osteoclastic bone resorption is a pressure-threshold-regulated phenomenon or merely a proportionally pressure-dependent phenomenon. In this study, a clear statistical criterion as an objective standard for the evaluation of histopathological bone resorption was established, and the relationship between the amount of continuous or intermittent compressive pressure exerted on the rat hard palate and induced osteoclastic bone resorption was studied based on this criterion. Eighty-five male rats of the Wistar strain, 15 weeks of age, were fitted with experimental dentures which were designed to exert a defined amount of continuous or intermittent compressive pressure on the intermolar region of the hard palate. No bone resorption was observed when continuous compressive pressure was &lt;&lt; 1.96 kPa or when intermittent compressive pressure was &lt;&lt; 9.8 kPa. In contrast, continuous compressive pressure ≧ 6.86 kPa or intermittent compressive pressure ≧ 19.6 kPa caused significant bone resorption in all rats studied. From these results, it was revealed that osteoclastic bone resorption under the denture base was a pressure-threshold-regulated phenomenon, and that the thresholds exist for the induction of bone resorption under the denture base by both continuous and intermittent compressive pressure, respectively. It was also clearly revealed from the results that the threshold for continuous compressive pressure is lower than that for intermittent compressive pressure.

    The purpose of the present study was to make a histometrical evaluation of bone resorptionunder the denture base caused by lack of self-cleaning as a result of coverage by the denture base.The experimental denture base was designed to make contact with the molar region of the palate of therat and to transmit no occlusal force to the tissues under the denture base. The denture base was not removedthroughout the experimental period. This procedure caused lack of self-cleaning, and it also caused continu-ous pressure to palatal tissues under the denture base by the accumulation of exfoliative horny cells, whichinduced bone resorption under the denture base.Five rats of each denture wearing group and control group were sacrificed every week during theobservation period of TO weeks after the insertion of the experimental denture base. Palatal tissues wereprestained with Villanueva bone stain, and then processed for undecalcified resin section for quantitative bonehistomorphometry. These specimens were analyzed using a two-dimensional graphic analyzing system.From the results of this study, it was revealed histometrically that bone resorption of palatal surface ofhard palate bone tissue initiated under the denture base caused by the lack of self-cleaning as a result ofcoverage by the denture base one week after, became most active two weeks after and ceased five weeks afterthe insertion of the experimental denture base. But on the nasal surface of hard palate bone tissue, boneresorption was not observed.

    Histopathological initial changes in denture supporting tissues, in relation to the changes inintensity of occlusal pressure exerted through the experimental denture base, was studied. The denture basewas applied to the palate of the molar region of the rat, and was installed to cover the palatal mucosa withoutany pressure unless occlusal force was exerted. The defined amount of occlusal pressure was transmitted todenture supporting tissue by allowing the denture base to subside the specified amount into palatal mucosa.The intensity of the occlusal pressure measured immediately after the insertion of the denture were 79. 7, 31. 7and 10.7 kPa. The animals were sacrificed at 2, 4, 7, 10 and 14 days after the insertion of the denture.Histopathological changes caused by the occlusal pressure were observed, and the changes in intensity of theocclusal pressure was also measured on every histopathological observation periods.Histopathological changes of the denture supporting tissues showed dependence on the intensity of theocclusal pressure, and also showed high correlation with the subsequent gradual changes of the pressure.Compression of Iamina propria mucosa, shortening of epithelial ridges, osteoclastic bone resorption, compres-sion of epithelial tissue except for epithelial ridges and inflammatory cell infiltration in the lamina propriamucosa were observed with the elapse of time. These tissue changes came out early and became severe byincreasing the occlusal pressure.

    c-fos expression in response to noxious mechanical stimulation of the peripheral receptive field was used to study the somatotopic representation of the oral mucous membrane and trigeminal cutaneous receptive fields in the trigeminal subnucleus caudalis and the cervical spinal dorsal horn. Fos-neurons (neurons with c-fos protein-like immunoreactivity) following stimulation of the cutaneous receptive field were found in laminae I and II of the first and second cervical segments of the spinal cord ipsilateral to the stimulation and exhibited a clear somatotopic segregation
    i.e., the fos-neurons responding to receptive fields in the mandibular, maxillary, and ophthalmic divisions were arranged in a mediolateral sequence. On the other hand, fos-neurons responding to the oral mucous membrane were found in the similar laminae of the rostral pole of subnucleus caudalis bilaterally. They were all found in the dorsalmost part of the subnucleus without segregation
    e.g., topographic distributions of fos-neurons resulting from the mandibular and maxillary gingival stimulations were indistinguishable. The central mechanism of trigeminal nociception is discussed with respect to the difference between intra- and extraoral receptive fields. © 1994 by Academic Press, Inc.

    Effect of denture removal during night time on histopathological changes in denture supporting tissues was investigated. Experimental denture base was applied to molar region of the hard palate of Wistar rat, and continuous pressure was exerted to the denture supporting tissues through the denture base. The experimental denture was removed during night time from the palate of the denture removal group, whereas the denture was worn continuously day and night in the denture wearing group. The palatal tissue was examined histopathologically up to 7 days after the insertion of the denture. In the denture wearing group, bone resorption and decrease of the thickness of epithelial tissue and connective tissue were observed. These tissue changes came out early and severe with increasing the continuous pressure. Whereas no remarkable tissue change was observed in the denture removal group throughout the experimental period. From these results, it was revealed that the half a day loading of mechanical continuous pressure to the denture supporting tissues would not cause bone resorption, and was suggested that denture removal during night time was effective for the preservation of denture supporting tissues.

    In the near future, opportunities for dental treatment for the elderly requiring long-term care will increase, and its importance will increase significantly.
    Therefore, in order to train dentists who can provide such dental care, we created a training scenario assuming dental care for the elderly requiring long-term care and repeatedly improved it. Scenarios were created for (1) wheelchair transfer / securing posture, (2) oral cleaning / conservative treatment training, (3) prosthetic treatment training, and (4) swallowing function test training. A questionnaire survey was conducted after training the trainee dentists based on these scenarios, and it was found that a significant improvement in knowledge and skills was observed, and that it was effective as a dental care education method in a super-aging society.

    This study was conducted to verify how the empathy of the trainee dentists and the medical interview skills change as the trainees gain clinical experiences during the clinical training period.
    The trainee dentists conducted initial medical interviews with simulated patients (SPs) twice, at the beginning and the end of their clinical training. The trainees completed a questionnaire to measure empathy just before each medical interview. The SPs and clinical instructors evaluated the trainees’ communication using questionnaires immediately after the medical interviews. The videotaped dialogue from the medical interviews was analyzed. There was no change in the empathy of the trainee dentists in their one-year postgraduate training, and it was suggested that the trainees becoming more focused on collecting dental information for diagnosis in medical interviews.

    A training dentist always experiences an inexperienced matter and is learning newly by dental clinical education. I can think the incident a beginner experiences by basic dental technology is universal in the learning process, but every time a learner will change for an educator, great educational effort has to tell repeatedly, and is needed. A training dentist is clinical by this research, and own learning system that I'll can utilize others' experience as the experience has been developed by vicarious experience animation-izing the incident I face. Reduction in educational effort is planned for for an educator as well as a main system can expect that I contribute to safety's and relief's being able to execute odontology clinical education.

    The text data of clinical records accumulated in the electronic portfolio system which we introduced into dental practice training education in Okayama University Hospital were collected and classified in every treatment. The clinical problems that dental practice beginners faced were analyzed using the text mining method. As a result, a lot of keywords related to dental procedures were listed in the item of "the impression" about contents of the treatment. On the other hand, there were many keywords related to the learning such as "study", "exercise" and "review" in the item of "the future task". Then, after sorting to reduce the quantity of the text data, they were refined and accumulated as knowledge data. An IT learning support system in clinical dentistry was produced experimentally using this knowledge database. When this system was evaluated, a relatively good evaluation was provided from trainee dentists.

    It is known widely that the pure titanium can form a direct interface between an implant and bone without intervening soft tissue, in so-called -osseointegration. On the other hand, the Ti6Al4V alloy used as a temporary implant, there is little information about interface observation with a living body tissue. Then, both interface observation was performed using the rats. The XPS revealed that the amounts of aluminum(Al) and vanadium(V) were below the detection limit on the superficial surface of the Ti6Al4V alloy implant. On the other hand, The EDS map of Ti disclosed that the outer layer contained more Ti than the inner layer.
    From this research, this was imagined to be one of the causes by which the good clinical results are obtained also in the Ti6Al4V alloy implant.

    It was reported that 10-MDP promoted formation of self-assembled layering at resin- hydroxyapatite interface when it was applied. Firstly, this study showed that the commercial 10-MDP based adhesives also formed the self-assembled layering of two 10-MDP molecules, joined by stable MDP-Ca salt formation, at the interface between human dentin and resin as similar to 10-MDP solution. The three-dimensional observation with FIB-SEM revealed that MDP-Ca salt was formed at the interface, extending into the adhesive (resin) layer. When we prepared adhesives containing MDP-Ca salts as a model of adhesion layer and measured its properties, polymerization shrinkage decreased and some of properties increased by adding the salt. It is concluded that MDP-containing adhesives do form nano-layering at the adhesive interface and MDP-Ca salt spread through the adhesive layer. The properties of adhesive layer with resin, salts and other residual tooth substances may influence the adhesion.

    義歯撤去時間の長さが,持続的圧力下の義歯床下組織における病理組織学的変化に対して与える影響に関しては,義歯床下組織を保全するうえで重要な情報であるにもかかわらず,詳細な検討は行われていない.本研究は,義歯床下組織の保全に関する検討の一環として,義歯撤去時間と持続的圧力下の義歯床下組織における病理組織学的変化との関連について検討することを目的とした.
    実験動物には15週齢のWistar系雄性ラット125匹(25匹×5群)を用いた.各動物の臼歯部口蓋の左側には,義歯床下組織に対して持続的圧力を加える可撤性義歯床を装着し,右側には義歯床を装着することなく経過させた.持続的圧力の初期設定値は,破骨細胞による骨吸収を惹起することが確認されている6.86kPaとした.可撤性義歯床は,観察期間を通じて毎日定時に撤去して,義歯床下組織ならびに義歯床の清掃を行った.5群のうちの1群の動物には,清掃後直ちに義歯床を再装着し,残る4群の動物には,清掃後にそれぞれ4,6,8または12時間の義歯撤去時間を設け,撤去時間終了後に義歯を再装着した.義歯の初回装着時から2,4,7,10および14日後の義歯撤去時間終了時に,各実験群の5匹ずつから口蓋組織を採取した.採取した組織は,通法に従って固定,脱灰の後にパラフィン包埋し,第一臼歯部において前頭的に4μmの厚さに薄切し,H-E染色を施して光顕下で観察した.
    その結果,義歯撤去時間の増加は,持続的圧力下の義歯床下組織に生じる病理組織学的変化を軽減した.また,持続的圧力によって上皮組織ならびに粘膜固有層に惹起される組織変化の防止に要する義歯撤去時間は,骨組織における組織変化の防止に要するそれに比べて長いことが示唆された.

    In this study, the experimental denture base on the hard palate of the molar region of osteoporotic rats was designed to cover without any mechanical pressure or to load continuous pressure (0.5, 1.5 or 3.4 kPa). Experimental osteoporosis was induced by ovariectomy and feeding on a low calcium diet. The histopathological changes and the changes in the argyrophilic nucleolar organizer region (AgNOR) counts in mucosal epithelium that was revealed to the cellular activity, induced by non-pressure covering or continuous pressure in the tissues uncler the experimental denture bases were examined. Regarding the histological changes induced by continuous pressure, this was evaluated in relation to the time course of the intensity of the continuous pressure. In the tissues under the denture base in osteoporotic condition with non-pressure covering, no histopathological changes caused by nonpressure covering were observed except for a transient slight proliferative reaction in the epithelial ridge. The following histopathological changes were observed in the tissues under the denture base in the osteoporotic condition bearing continuous pressure ; (1) bone resorption was induced on the periosteal surface in the osteoporotic-3.4kPa group, and on the pressure side of the endocortical surface in the osteoporotic-1.5 and -3.4kPa group. (2) histopathological changes in the tissues under the denture base in experimental osteoporosis bearing continuous pressure had an intimate relationship with the initial intensity and the time course of continuous pressure, and with the AgNOR counts in mucosal epithelium.

    The effect of diabetes mellitus on-bone dynamics in denture supporting tissue has not been investigated enough. The purpose of this study was to investigate the effect of diabetes mellitus on bone resorption in the tissues under denture base bearing masticatory pressure by using bone histomorphometry.
    Two-hundred and fifty streptozotocin-induced diabetic male rats (n=50X5 groups) of Wistar strain were used in this study. Denture base was applied to the molar region of the hard palate at 22 weeks of age. In loaded groups, the denture base were designed to load a masticatory pressure of 1.0, 10.0 or 20.0 kPa to the palate, respectively. In covering group, the denture base was designed to contact with the palate without any mechanical pressure. The non-denture-wearing group received no intentional treatment. The cleansing of the palate and removable denture base was carried out at 3 or 4 day intervals. Palatal tissue block was excised from 5 rats of each experimental group after the denture insertion at one week interval. The specimens were stained with Villanueva bone stain, embedded in methyl-methacrylate, and ground frontally to 50μm thickness. Eroded surface and osteoclast surface were calculated by using two-dimensional graphic analyzing system. Amount of bone resorption was calculated as (A)-(B) ; (A) Formed bone tissue during 12 weeks prior to the denture insertion in covering group, (B) Remained bone tissue after the end of bone resorption in each bone resorbed group at each experimental period.
    Bone resorption was observed in 10.0 and 20.0 kPa groups until 6 weeks after the denture insertion, respectively. Total amount of bone resorption was 189±38μm in 10.0 kPa group and 266±27μm in 20.0 kPa group. Comparing these results with results in normal rats in same condition as this study, it is showed that diabetes mellitus prolongs the period of bone resorption and increases total amount of bone resorption.

    実験動物にはストレプトゾトシン誘発糖尿病ラット5群(1群35匹)を用いた.これらのうちの4群の臼歯部口蓋を対象として,安静時には義歯床下組織と無圧の状態で接触し,咀嚼時には0(無圧群),13,50および100μm沈下して(各沈下群)義歯床下組織に咀嚼圧を加える義歯床を装着した.義歯床下粘膜および義歯床の清掃は3〜4日毎に行った.残る1群は義歯非装着群とし,義歯床を装着することなく経過させた.義歯床装着の3日,1,2,4,8,12および20週後に各群の5匹ずつから口蓋粘膜を採取して通法に従ってパラフィン切片を作成し,これにAgNOR染色を施して基底細胞の細胞核1個あたりの平均AgNOR数の各実験群毎に求めた.各観察期間毎に各実験群間の有意差検定(Mann-Whitney U-test)を行った.
    無圧群と義歯非装着群の示したAgNOR数は,観察期間を通じて両者が同様で,ほぼ一定の値を示した.各沈下群の示したAgNOR数は,3日後にはいずれの沈下群においても無圧群に比較して有意に減少し,その後8週後までは経時的に増加したが無圧群よりも有意に小さい値を示し,以降20週後に至るまで無圧群に比べて有意に小さい値を持続した.無圧群と義歯非装着群が示したAgNOR数は,観察期間を通じて本研究と同一条件下で観察した健常ラットの場合よりも小さく,これらとの間にほぼ一定の差を持続した.すなわち,糖尿病は,義歯床による無圧の被覆下の義歯床下粘膜上皮細胞におけるAgNORには影響を与えないことが示された.一方,各沈下群が示したAgNOR数は,観察期間を通じて同一条件下の健常ラットの場合よりも小さな値を示し,その減少量は,義歯非装着群および無圧群においてみられた糖尿病発症によるそれよりも大きかった.
    従って糖尿病は,AgNOR数を指標とした咀嚼圧下の義歯床下粘膜上皮細胞の増殖活性を低下させることが示された.
