Mesenchymal stem cells (MSCs) are known to play important roles in the repair of lost or damaged tissues and immunotolerance. On the other hand, aging is known to impair MSC function. However, little is currently known about how aged MSCs affect the host response to the local inflammatory condition and tissue deterioration in periodontitis, which is a progressive destructive disease of the periodontal tissue potentially leading to multiple tooth loss. In this study, we examined the relationship between aging-induced impairment of MSC function and the severity of periodontal tissue destruction associated with the decrease in host immunomodulatory response using a ligature-induced periodontitis model in young and aged mice. The results of micro computerized tomography (micro-CT) and histological analysis revealed a more severe bone loss associated with increased osteoclast activity in aged (50-week-old) mice compared to young (5-week-old) mice. Immunostaining analysis revealed that, in aged mice, the accumulation of inflammatory T and B cells was higher, whereas the percentage of platelet-derived growth factor receptor α (PDGFRα)+ MSCs, which are known to modulate the apoptosis of T cells, was significantly lower than in young mice. In vitro analysis of MSC function showed that the expression of surface antigen markers for MSCs (Sca-1, CD90, CD146), colony formation, migration, and osteogenic differentiation of aged MSCs were significantly declined compared to those of young MSCs. Moreover, a significantly higher proportion of aged MSCs were positive for the senescence-associated β galactosidase activity. Importantly, aged MSCs presented a decreased expression of FAS-L, which was associated with a lower immunomodulatory property of aged MSCs to induce T cell apoptosis in co-cultures compared with young MSCs. In summary, this is the first study showing that aging-induced impairment of MSC function, including immunomodulatory response, is potentially correlated with progressive periodontal tissue deterioration.

Bone morphogenetic protein-2 (BMP-2) and fibroblast growth factor-2 (FGF-2) have been regarded as the major cytokines promoting bone formation, however, several studies have reported unexpected results with failure of bone formation or bone resorption of these growth factors. In this study, BMP-2 and FGF-2 adsorbed into atellocollagen sponges were transplanted into bone defects in the bone marrow-scarce calvaria (extramedullary environment) and bone marrow-abundant femur (medullary environment) for analysis of their in vivo effects not only on osteoblasts, osteoclasts but also on bone marrow cells. The results showed that BMP-2 induced high bone formation in the bone marrow-scarce calvaria, but induced bone resorption in the bone marrow-abundant femurs. On the other hand, FGF-2 showed opposite effects compared to those of BMP-2. Analysis of cellular dynamics revealed numerous osteoblasts and osteoclasts present in the newly-formed bone induced by BMP-2 in calvaria, but none were seen in either control or FGF-2-transplanted groups. On the other hand, in the femur, numerous osteoclasts were observed in the vicinity of the BMP-2 pellet, while a great number of osteoblasts were seen near the FGF-2 pellets or in the control group. Of note, FCM analysis showed that both BMP-2 and FGF-2 administrated in the femur did not significantly affect the hematopoietic cell population, indicating a relatively safe application of the two growth factors. Together, these results indicate that BMP-2 could be suitable for application in extramedullary bone regeneration, whereas FGF-2 could be suitable for application in medullary bone regeneration.

Medication-related osteonecrosis of the jaw (MRONJ) is a severe pathological condition associated mainly with the long-term administration of bone resorption inhibitors, which are known to induce suppression of osteoclast activity and bone remodeling. Bone Morphogenetic Protein (BMP)-2 is known to be a strong inducer of bone remodeling, by directly regulating osteoblast differentiation and osteoclast activity. This study aimed to evaluate the effects of BMP-2 adsorbed onto beta-tricalcium phosphate (β-TCP), which is an osteoinductive bioceramic material and allows space retention, on the prevention and treatment of MRONJ in mice. Tooth extraction was performed after 3 weeks of zoledronate (ZA) and cyclophosphamide (CY) administration. For prevention studies, BMP-2/β-TCP was transplanted immediately after tooth extraction, and the mice were administered ZA and CY for an additional 4 weeks. The results showed that while the tooth extraction socket was mainly filled with a sparse tissue in the control group, bone formation was observed at the apex of the tooth extraction socket and was filled with a dense connective tissue rich in cellular components in the BMP-2/β-TCP transplanted group. For treatment studies, BMP-2/β-TCP was transplanted 2 weeks after tooth extraction, and bone formation was followed up for the subsequent 4 weeks under ZA and CY suspension. The results showed that although the tooth extraction socket was mainly filled with soft tissue in the control group, transplantation of BMP-2/β-TCP could significantly accelerate bone formation, as shown by immunohistochemical analysis for osteopontin, and reduce the bone necrosis in tooth extraction sockets. These data suggest that the combination of BMP-2/β-TCP could become a suitable therapy for the management of MRONJ.

上部構造装着後の辺縁軟組織の退縮を抑止するためには,インプラント体の唇(頬)側に2mm以上の厚みの硬組織が必要とされている.そのため,既存骨の厚みが薄い場合は,何かしらの硬組織増生術が必要とされる.従来,高度に萎縮した顎堤に対してはブロック骨移植が推奨されてきたが,いびつで複雑な表面形態をしている母床骨に,ブロック骨を適合させることは容易ではない.また,ブロック骨の適合が不良の場合は,生着不良を引き起こすことがあることも問題であった.そのようななか,Dr. URBANは粉砕自家骨と吸収スピードの遅い骨補填材(脱タンパク化ウシ骨ミネラル)を混合した移植材を,吸収性メンブレンとピンで固定するソーセージテクニックを発表した.このテクニックは,顆粒状の混合補填材を用いるため母床骨との適合を心配する必要がなく,メンブレンは創裂開率が低い吸収性メンブレンを用いているため,比較的安全な術式であると考えられる.しかし,増生後のグラフト吸収量が多いことが難点であり,特に外側からの圧が集中する唇(頬)側歯槽堤のショルダー部分での吸収が顕著なため,インプラント体埋入時に追加の骨再生誘導法(Guided Bone Regeneration:GBR)が必要になる場合も多い.また,垂直的なスペース保持能力が乏しいことから,垂直的な増生を目的にする場合や,水平的な増生においても歯槽堤のショルダー部分に十分な厚みの硬組織を構築したい場合は,チタンフレーム付き非吸収性メンブレンの使用が望ましいと考えられる.(著者抄録)

AIM: Previous studies on the association between intraoral conditions and mortality in community-dwelling older individuals reported that fewer present teeth (PT) are significant risk factors for mortality. However, how the number of PT relative to the number of functional teeth (FT), including both present and rehabilitated teeth, influences mortality has not been investigated fully. This study examined the impact of the number of FT on mortality among community-dwelling Japanese older adults. METHODS: This study was a retrospective, observational and population-based follow-up study, which examined 1188 older individuals who participated in an annual geriatric health examination from 2009 to 2015. The average follow-up period was 1697.0 ± 774.5 days. The primary outcome was all-cause mortality at follow-up. The numbers of PT and FT of each participant were counted during an oral examination. In addition, demographics, clinical variables, blood nutrient markers, physical functions and perceived masticatory function were measured. RESULTS: Kaplan-Meier analysis, followed by a log-rank test, revealed that fewer PT (P < 0.001) and FT (P = 0.002) were significantly associated with a reduced survival rate. Cox's proportional hazard analysis indicated that the number of FT, but not the number of PT, was a significant independent mortality risk factor after adjusting for demographics, clinical variables, nutrient markers and physical functioning (P = 0.036, hazard ratio: 2.089). CONCLUSIONS: Current results suggest that the number of FT more strongly predicts all-cause mortality than the number of PT among community-dwelling older adults. Further studies are necessary to consider the confounding of socioeconomic status and disability status. Geriatr Gerontol Int 2020; ••: ••-••.

近年,重度歯周炎が原因で歯を失った患者にインプラント治療を行う機会も多くなり,患者のQOLの向上に貢献している.重度歯周炎患者にインプラント治療を行った場合,最も懸念される問題は,術後のインプラント周囲炎の発症である.歯周炎の既往のある患者では,既往がない患者と比較して,術後長期に経過するとインプラント周囲炎の発症率が高くなることが報告され,歯周炎の既往は喫煙と同様にインプラント周囲炎のリスクファクターと考えられている.そこで筆者らは,重度歯周炎患者にインプラント治療を行う場合,潜在的ないくつかの重度歯周炎患者特有の問題を把握する必要があると考えている.1)残存天然歯に深い歯周ポケットが存在する可能性がある.2)欠損部歯槽堤が高度に吸収している可能性がある.3)支持骨を喪失しているため残存歯が動揺している場合がある.4)歯周炎の進行に伴い病的な歯の移動が存在し,咬合の不調和が存在することがある.5)既存の不正咬合が誘因となって歯周炎が進行し,歯を喪失していることがある.これらの問題は,術後の歯周組織やインプラント周囲組織の清掃性を悪化させ,かつ天然歯やインプラント上部構造への外傷力となりうる.すなわち,術後の長期的な安定を得るためには,的確な診断の下,徹底した歯周治療やインプラント周囲の硬・軟組織の再建ならびに安定した咬合関係が得られるような包括的な治療計画が望まれる.(著者抄録)

OBJECTIVE: This study aims to verify the associations among sleep bruxism (SB), sleep arousal (SA) and concurrent body movements. MATERIAL AND METHODS: Subjects underwent a standard overnight polysomnography test and audio-video recordings. Sleep quality was evaluated according to the Rechtschaffen and Kales criteria, while SA was determined as per the American Sleep Disorders Association criteria. Analyses were performed by an external institution after masking of the subjects' information. SB was assessed based on the presence/absence of rhythmic masticatory muscle activity (RMMA) episodes, which were identified by using electromyography of the masseter muscle. The observed simultaneous movements included lower leg movement (LLM), swallowing, face scratching, head movement, body movement, eye blinking, coughing, licking, sighing, body scratching, lip sucking, somniloquy and yawning. The LLM was determined visually, as well as through an increase in the tibialis electromyogram signal. Other movements were visually assessed using audio-video recordings. The incidences of all the simultaneous movements were compared between RMMA with intercurrent SA (SAwRMMA; RMMA episode derived from a masseter electromyogram showing more than 10% of maximum voluntary contraction) and SA without RMMA (SAw/oRMMA). RESULTS: Fourteen subjects were included in this study (females/males: 4/10, mean age: 31.5 ± 5.7 years). Among these, LLM, swallowing, body movement, licking, body scratching and lip sucking were frequently observed in SAwRMMA episodes than in SAw/oRMMA episodes, significantly. However, the non-specific simultaneous movements were higher observed in SAw/oRMMA episodes than that in SAwRMMA. CONCLUSION: Our results suggest that SB is concurrently activated with LLM in relation to arousal.

OBJECTIVE: To estimate the effect of a vibratory splint (VibS) in reducing sleep clenching (SC) and TMD pain. METHODS: Target sample was consecutive 19 TMD patients attending the Orofacial Pain Clinic at FFO-FOUSP. Patients used the VibS or acrylic occlusal splint (OS) as control for 14 days. Outcome variables were SC frequency and pain, assessed by a portable electromyography detector-analyzer (BiteStrip™) and 100 mm VAS, respectively. Statistical analyses were performed with two-way repeated measures ANOVA, and analysis of covariance (ANCOVA). RESULTS: VibS promoted a marked decrease, whereas acrylic OS increased SC frequency after two weeks of use. Due to a significant difference in initial VAS levels between VibS and control group, the effect of the two splints on TMD pain could not be clearly estimated. CONCLUSION: The results suggested that VibS can potentially be used to reduce SC frequency, although further studies with larger sample size are necessary to confirm these findings.

AIM: The importance of oral care has been recognized for the prevention of airway infections in older individuals who require long-term care. The present prospective cohort study was carried out a decade ago to identify risk factors with numerous intraoral conditions as possible predictors involved in the onset of pneumonia and acute viral respiratory infection (AVRI) in older people requiring long-term care during a 6-month follow-up period (including winter). METHODS: This study included 1785 older individuals residing in 31 long-term care facilities in which dental hygienists were involved in instruction on daily oral care. Primary end-points were development of pneumonia and AVRI during the 6-month follow-up period. Several factors related to each participant's general condition, oral environment, swallowing function and vaccinations (or lack thereof) were evaluated by calibrated dentists and dental hygienists before the study onset. RESULTS: During the 6-month follow-up period, 74 participants (4.1%) developed pneumonia, and 28 participants (1.6%) developed AVRI. Cox proportional hazard analysis showed that poor nutritional status and the presence of dysphagia were significant risk factors for pneumonia onset. The presence of dry mouth and halitosis were significant risk factors for AVRI. CONCLUSIONS: This prospective multicenter cohort study identified poor nutritional status and dysphagia as independent risk factors for the development of pneumonia, and dry mouth and halitosis as independent risk factors for the development of AVRI in older people who require long-term care and who routinely receive professional oral care.
