    PURPOSE: This study aimed to investigate the relationship between dental metal allergy, periodontitis, and palmoplantar pustulosis among patients from a dental metal allergy clinic over a period of 8 years. METHODS: This study included 436 patients who visited our dental metal allergy clinic between April 1, 2009 and March 31, 2016. Diagnoses of skin diseases, periodontal records, dental metal series patch test results, and electron probe microanalysis (EPMA) data were obtained from medical records. Relative risk (RR) values were estimated from these data. RESULTS: Of the 359 patients who underwent the patch test, 241 showed a positive reaction. Of the 187 patients who underwent EPMA, 113 had allergenic metals in their dental prostheses. These patients were suspected to have a dental metal allergy. Furthermore, 150 of the 436 patients were diagnosed with palmoplantar pustulosis (PPP). The RR of metal allergy between patients with PPP and healthy subjects was 3.88. The RR of periodontal disease between patients with PPP and PPP-negative patients in the national average was 2.54. CONCLUSIONS: In this study, both dental metal allergy and periodontitis showed a high RR for PPP.

    © 2020, The Author(s). The micro- and nanosize surface topography of dental implants has been shown to affect the growth of surrounding cells. In this study, standardized and controlled periodic nanopatterns were fabricated with nanosized surface roughness on titanium substrates, and their influence on bone marrow stromal cells investigated. Cell proliferation assays revealed that the bare substrate with a 1.7 nm surface roughness has lower hydrophilicity but higher proliferation ability than that with a 0.6 nm surface roughness. Further, with the latter substrate, directional cell growth was observed for line and groove patterns with a width of 100 nm and a height of 50 or 100 nm, but not for those with a height of 10 or 25 nm. With the smooth substrate, time-lapse microscopic analyses showed that more than 80% of the bone marrow cells on the line and groove pattern with a height of 100 nm grew and divided along the lines. As the nanosized grain structure controls the cell proliferation rate and the nanosized line and groove structure (50–100 nm) controls cell migration, division, and growth orientation, these standardized nanosized titanium structures can be used to elucidate the mechanisms by which surface topography regulates tissue responses to biomaterials.

    © 2020 Elsevier Inc. Osteoclast and osteoblast are essential for proper bone development and remodeling as well as recovery of bone fracture. In this study, we seek chemical compounds that enhance turnover of bone metabolism for promoting bone healing. First, we screen a chemical library which includes 378 compounds by using murine pre-osteoclastic RAW264.7 cells to identify compounds that promote osteoclastic differentiation. We find that two ROCK (Rho-associated coiled-coil kinase) inhibitors, HA-1077 (Fasudil) and Y-27632, enhance osteoclastogenesis. Subsequently, we identify that these two compounds also increase osteoblastic differentiation of MC3T3-E1 cells. Finally, our in vivo experiment shows that the local administration of ROCK inhibitors accelerate the bone healing of the rat calvarial defect.

  • Insulin-like growth factor binding Protein-3 suppresses osteoblast differentiation via bone morphogenetic protein-2. Reviewed International journal

    Bone augmentation therapy is used in dental implantation. While techniques to induce bone formation are generally successful, the maintenance of bone mass is more difficult. Therefore, it is important to understand the mechanisms that regulate this process. Insulin-like growth factor-1 (IGF-1) is one of the most abundant growth factors that regulate bone mass, promote osteoblast differentiation, and accelerate bone formation. The activity of IGF-1 is regulated by IGF-binding proteins (IGFBPs). IGFBP-3 forms a ternary complex with IGF-1, extending its half-life in the circulating system. Therefore, IGFBP-3 acts as a stabilizer and transporter of IGF-1. Recent studies reported new IGF-1-independent functions of IGFBP-3 related with bone metabolism. In this study, we investigated the function of IGFBP-3 in osteoblast differentiation. Our results showed that IGFBP-3 decreases the expression of osteoblast differentiation markers, whose expression is enhanced by bone morphogenetic protein-2 (BMP-2). IGFBP-3 also reduced BMP-2 effect on ALP activity and mineral nodule formation. In addition, IGFBP-3 suppresses the activity of the Smad Binding Element (SBE) reporter, induced by BMP-2 signaling. These results suggest that IGFBP-3 inhibits osteoblast differentiation through the BMP-2 signal pathway, and that IGFBP-3 might play a role in bone mass maintenance in an IGF-1-dependent and -independent manner.

    PURPOSE: Zirconia is a good candidate material in the dental field. In this study, we evaluated biological responses against a zirconia drill using a bone cavity healing model. MATERIALS AND METHODS: Zirconia drills, stainless steel drills, and the drilled bone surface were observed by scanning electron microscopy (SEM), before and after cavity preparation. For the bone cavity healing model, the upper first and second molars of Wistar rats were extracted. After 4 weeks, cavities were prepared with zirconia drills on the left side. As a control, a stainless steel drill was used on the right side. At 3, 7, and 14 days after surgery, micro-CT images were taken. Samples were prepared for histological staining. RESULTS: SEM images revealed that zirconia drills maintained sharpness even after 30 drilling procedures. The bone surface was smoother with the zirconia drill. Micro-CT images showed faster and earlier bone healing in the zirconia drill cavity. On H-E staining, at 7 days, the zirconia drill defect had a smaller blank lacunae area. At 14 days, the zirconia drill defect was filled with newly formed bone. CONCLUSIONS: The zirconia drill induces less damage during cavity preparation and is advantageous for bone healing.

    ヒストン脱アセチル化酵素阻害剤(HDACI)は抗癌剤、抗てんかん薬として臨床応用される薬剤である。HDACIは遺伝子発現過程においてクロマチンリモデリングに関与し、遺伝子発現を活性化することが知られている。骨形成関連においてはRunx2の安定化に関与し骨芽細胞の分化を促進する作用が報告されている。そこで本研究では、はじめに上顎骨円筒形骨欠損修復モデルを用いてHDACIの全身投与における骨形成能の賦活化を検討することとした。HDACIにはバルプロ酸(Valproic acid(VPA))を使用し、投与法は腹腔内投与、投与期間は円筒形骨欠損形成前7日間とした。VPA全身投与群では窩洞内新生骨形成能促進、円筒形骨欠損治癒促進を示す像が窩洞形成14日から21日後にかけて観察された。次に頭蓋骨限界径骨欠損細胞移植モデルを作製し、大腿骨より採取した骨髄間質細胞をVPA処理し欠損部へ移植した。VPA処理細胞移植窩洞では対照群と比較して窩洞内の石灰化の亢進が観察された。本研究より骨増成法におけるHDACIの有効性が示され、更にHDACIの多機能性を応用した新規骨増成法開発の可能性が示唆された。(著者抄録)
