Abstract Background Orthodontic tooth movement (OTM) has been shown to induce osteocyte apoptosis in alveolar bone shortly after force application. However, how osteocyte apoptosis affects orthodontic tooth movement is unknown. The goal of this study was to assess the effect of inhibition of osteocyte apoptosis on osteoclastogenesis, changes in the alveolar bone density, and the magnitude of OTM using a bisphosphonate analog (IG9402), a drug that affects osteocyte and osteoblast apoptosis but does not affect osteoclasts. Material and methods Two sets of experiments were performed. Experiment 1 was used to specifically evaluate the effect of IG9402 on osteocyte apoptosis in the alveolar bone during 24 h of OTM. For this experiment, twelve mice were divided into two groups: group 1, saline administration + OTM24-h (n=6), and group 2, IG9402 administration + OTM24-h (n=6). The contralateral unloaded sides served as the control. The goal of experiment 2 was to evaluate the role of osteocyte apoptosis on OTM magnitude and osteoclastogenesis 10 days after OTM. Twenty mice were divided into 4 groups: group 1, saline administration without OTM (n=5); group 2, IG9402 administration without OTM (n=5); group 3, saline + OTM10-day (n=6); and group 4, IG9402 + OTM10-day (n=4). For both experiments, tooth movement was achieved using Ultra Light (25g) Sentalloy Closed Coil Springs attached between the first maxillary molar and the central incisor. Linear measurements of tooth movement and alveolar bone density (BVF) were assessed by MicroCT analysis. Cell death (or apoptosis) was assessed by terminal dUTP nick-end labeling (TUNEL) assay, while osteoclast and macrophage formation were assessed by tartrate-resistant acid phosphatase (TRAP) staining and F4/80+ immunostaining. Results We found that IG9402 significantly blocked osteocyte apoptosis in alveolar bone (AB) at 24 h of OTM. At 10 days, IG9402 prevented OTM-induced loss of alveolar bone density and changed the morphology and quality of osteoclasts and macrophages, but did not significantly affect the amount of tooth movement. Conclusion Our study demonstrates that osteocyte apoptosis may play a significant role in osteoclast and macrophage formation during OTM, but does not seem to play a role in the magnitude of orthodontic tooth movement.

Significant Difference

Background: Tooth extraction can cause alveolar resorption, and will reduce the denture retention. The process of bone resorption looks like the process of osteoporosis. Calcium and vitamin D supplementation is the rational therapy for minimizing bone loss. Miacalcic is the drug of choice for osteporotic patient. Purpose: This study is aimed to know whether the combination of miacalcic, calcium lactate, and vitamin C are effective in inhibiting post extracted alveolar resorption. Methods: Thirty three healthy postmenopausal women were chosen as samples and they were classified randomly into control group (without treatment), 1st experiment group (treatment was started 3 months post extraction), and 2nd experiment group (treatment was started at the 2nd day post extraction). The treatment was done by giving miacalcic nasal spray, calcium lactate 500 mg and vitamin C 100 mg tablets every morning in 10 days every month for 3 months. X-ray photo of the post extracted area were taken an hour, 3 months, and 6 months post-extraction. Results: After 6 month, there was significant difference in buccolingual thickness decreasing among three groups (p<0.05). The maximum mean difference of buccolingual thickness decreasing was 0.72 mm, between control and 2nd experiment groups. There was no significant difference about decreasing bone density among them (p>0.10). The maximum difference of the mean of density decreasing was 1,906 g/cm2/mm between control and 2nd experiment groups. The increasing density mostly occurred in the 2nd experiment group. Conclusion: The combination of miacalcic, calcium lactate, and vitamin C are effective for inhibiting alveolar resorption, although statistically there was no significant difference about bone density decreasing. The sooner this treatment is given the better result will be achieved.Latar belakang: Pencabutan gigi menyebabkan resorpsi tulang alveolaris, dan akan mengurangi retensi geligi tiruan. Proses resorpsi tulang alveol pada osteoporosis mirip dengan proses resorpsi tulang pada penyembuhan luka bekas pencabutan. Miacalcic adalah obat utama untuk penderita osteoporosis. Kalsium dan vitamin D merupakan terapi yang rasional untuk meminimalkan resorpsi tulang. tujuan: Membuktikan apakah kombinasi miacalcic, kalsium laktat, and vitamin C juga efektif menghambat resorpsi tulang alveol pasca pencabutan. Metode: Sampel 33 wanita postmenopause yang sehat, terbagi secara acak ke dalam kelompok kontrol (tanpa perlakuan), kelompok eksperimen 1 (perlakuan mulai 3 bulan pasca pencabutan) dan kelompok eksperimen 2 (perlakuan mulai hari kedua pasca pencabutan). Perlakuannya yaitu: pemberian miacalcic semprot hidung, tablet kalsium laktat 500 mg dan vitamin C 100 mg setiap pagi, 10 hari dalam sebulan, selama tiga bulan. Foto sinar-X dari regio pasca pencabutan dibuat satu jam, 3 bulan, dan 6 bulan pasca pencabutan. Hasil: 6 bulan pasca-cabut, ada beda bermakna perihal selisih tebal bukolingual tulang alveol antar ketiga kelompok (p<0,05). Rerata penurunan ketebalan ini maksimal sebanyak 0.72 mm, antara kelompok kontrol dan kelompok eksperimen 2. Penurunan kepadatan tulang antar ketiga kelompok tidak bermakna (p>0,10). Beda maksimum rerata kepadatan tulang antara kelompok kontrol dan kelompok eksperimen 2 sebesar 1,906 g/cm2/mm. Peningkatan kepadatan terbanyak dialami anggota kelompok eksperimen 2. Kesimpulan: Kombinasi miacalcic, kalsium laktat, vitamin C efektif menghambat resorpsi tulang alveolaris, walaupun secara statistik beda penurunan kepadatan tidak bermakna. Makin awal pemberian perlakuan, hasilnya akan lebih baik.

The Relationship

Objectives: Sinus floor elevation and augmentation surgery is widely used as a reliable procedure to increase insufficient bone height in the posterior maxillary area. The purpose of the present clinical study was to determine the associations between periodontal bone loss (PBL), maxillary sinus lateral bone wall thickness, age, and gender using cone-beam computerized tomography (CBCT). Materials and Methods: The current retrospective study consists of 716 maxillary sinus CBCT images of 358 patients. The CBCT scans were assessed to detect the relationship between lateral wall thickness and PBL. ANOVA and Student t test analysis were used to determine the influence of PBL on sinus lateral wall thickness. Results: Sinus lateral wall thickness was significantly associated with PBL (p < 0.05) at 3, 13, and 15 mm height. There was no significant association between lateral wall thickness and gender (p > 0.05). However, there was a significant association between lateral wall thickness at 3 and 13 mm and age (p < 0.05). There were significant associations between PBL and age (p < 0.001), and PBL and gender (p < 0.05). Conclusions: PBL might have an association with maxillary sinus lateral bone wall thickness. Further studies are needed to confirm this possible relationship.
