Latar belakang dan tujuan: Prevalensi osteoporosis di Indonesia cukup tinggi disertai peningkatan risiko patah tulang terutama pada wanita. Pemeriksaan kepadatan massa tulang dengan DXA merupakan baku emas dalam mendiagnosis osteopenia maupun osteoporosis dan memperkirakan risiko patah tulang berdasarkan nilai T-score, namun ketersediaan perangkat DXA sangat terbatas di wilayah Indonesia. Indeks ketebalan korteks merupakan salah satu parameter sederhana, objektif, dan mudah diterapkan pada radiografi konventional dalam memperkirakan kepadatan massa tulang, namun perlu dibuktikan korelasinya dengan nilai T-score. Metode: Uji korelatif dengan pendekatan potong lintang pada nilai indeks ketebalan korteks femur proksimal menggunakan radiografi konvensional dan T-score kolum femur menggunakan DXA berdasarkan database populasi Indonesia, terhadap 31 subjek penelitian, menggunakan data sekunder dalam kurun waktu Juli 2012 sampai Juni 2016. Hasil: Dengan uji korelasi Pearson, didapatkan nilai p<0,000 dan r=0,76 antara nilai indeks ketebalan korteks femur proksimal menggunakan radiografi konvensional dan T-score kolum femur menggunakan DXA. Kesimpulan: Terdapat korelasi positif yang kuat antara nilai indeks ketebalan korteks femur proksimal menggunakan radiografi konvensional dan T-score kolum femur menggunakan DXA. ...... Background and Objective: The prevalence of osteoporosis in Indonesia is high with increased risk of fractures, especially in women. Examination of bone density by DXA is the gold standard in the diagnosis of osteopenia or osteoporosis and predicts fracture risk based on the T-score, but the availability of DXA devices in Indonesia is very limited. The cortical thickness index is a simple, objective parameter, and easily applied to conventional radiography in estimating bone density, but needs to be proven its correlation with the T-score. Methods: A cross sectional correlation study between the cortical thickness index of proximal femur by conventional radiography and T-score of femoral neck by DXA based on population database in Indonesia, conducted in 31 subjects in the period of July 2012 to June 2016. Results : With the Pearson correlation test, there is a significant correlation (p < 0.001 and r = 0.76) between the cortical thickness index of proximal femur by conventional radiography and T-score of femoral neck by DXA. Conclutions: There is a strong positive correlation between the cortical thickness index of proximal femur by conventional radiography and T-score of femoral neck by DXA.

......Introduction Bone density disorders are currently a public health problem that is currently a public health problem. Many factors have an impact on bone density. The purpose of the study was to determine the relationship of individual risk factors such as gender, age, body mass index, smoking, sleep quality, diabetes, physical activity, mental emotional disorders (stress), and night shift length with abnormal bone mass density in night shift workers and to determine which interactions between variables are most responsible for workers with abnormal bone density.  Methods This study was an analytic cross-sectional study in 80 RSON workers to see bone density with bone mineral density in night shift workers with associated factors namely gender, age, body mass index, smoking, sleep quality, diabetes, physical activity, mental emotional disorders (stress), and length of night shift. This study was conducted from November 2022-April 2023. The independent variables were night shift workers, age, gender, body mass index, smoking, mental emotional disorders (stress), sleep quality, diabetes, and physical activity. Bone Mass Density (BMD) score as the dependent variable. And the resulting outcome is that there is an association between abnormal bone density with gender, age, body mass index, smoking, sleep quality, diabetes, physical activity, mental emotional disorders (stress), and length of night shift. Results The study subjects were dominated by women as many as 53 participants (66.3%). Age was divided into 2 because the median age was 38 years. The results obtained in the age of workers, most workers are less than 38 years old as many as 42 workers (52.5%). Body mass index is dominated by obese body mass index as many as 52 workers (65%). Workers who have a non-smoking habit are 60 workers (75%). Diabetes in workers is dominated by not having diabetes as many as 70 workers (86.3%). The results of the filling of the sleep quality obtained the most results in poor sleep quality as many as 47 workers (58.75%) and mental emotional disorders (stress) in workers derived from filling out the Self Reporting Questionnaire -20 (SRQ-20) questionnaire obtained high results in the absence of stress in workers as many as 69 workers (86.25%). In the results of filling out the International Physical Activity Questionnaire (IPAQ) questionnaire for assessing physical activity in workers, the dominant result of moderate physical activity was 49 workers (61.3%). The length of night shift work carried out by all workers who participated in this study was found to be dominated by workers who worked for less than 10 years as many as 43 workers (53.75%). Regarding bone density in workers, it was found that 60 workers (75%) had normal bone density. In multivariate analysis, all variables can explain the decrease in bone density by 36.7%. Multivariate analysis was conducted to determine the interaction between variables and to determine which variables are most responsible as risk factors that affect bone density. From the multivariate analysis using the Backwards Conditional Method, it was found that the most dominant variables for the occurrence of abnormal BMD were normal-thin BMI, age> 38 years, moderate physical activity, light physical activity, smoking, and diabetes mellitus. With an R square value of 0.367. Multivariate analysis of the enter method was re-conducted by entering the above variables and adding the night shift variable, and the results were obtained in table 7 with a Nagelkerke R Square value of 0.378. The Odds Ratio(OR) probability of workers from night shift duration >20 years for abnormal BMD is 1.454x greater than shift duration <20 years, but not significant. The most dominant variables at risk of abnormal BMD are diabetes and smoking. Where the risk of abnormal BMD in night shift workers with diabetes is 8.624x higher than in night shift workers with no diabetes. In night shift workers who smoke, the risk of abnormal BMD is 4.963x higher than that of night shift workers who do not smoke. The risk of abnormal BMD in night shift workers with moderate physical activity decreased by 80% compared to night shift workers who did not have moderate physical activity. Conclusion In the prevalence of bone density in night shift workers in the workplace with a division of 60 normal workers (Normal ≥ -1 SD) (75%) and 20 workers (25%) there is abnormal bone density (Osteopenia -1 SD to -2.5 SD, Osteoporosis ≤ -2.5 SD). There was an association between age >38 years, diabetes, and moderate - high activity with abnormal bone density in night shift workers. In multivariate analysis, all variables could explain the decrease in bone density (BMD) score by 36.7%. There were significant variables between moderate activity, diabetes, and smoking.

Today jawbone radiographic studies have shifted to 'bone quality'. The jawbone quality indicator which is often used is trabeculation density. To obtain accurate interpretation, analysis of jawbone quality needs modern radiographic imaging modalities that still very limited in Indonesia. In prosthetic dentistry analysis of tarabecular bone density in postmenopause women is very important to anticipate the possibility of osteoporotic cases. Because of inadequacy of human eye sight, information obtained from plain conventional radiographic is very limited. With digitized conventional radiogram, dentist could obtain more accurate information to analyze radiographic trabeculation density in Indonesia. The aim of this study is to get more quantitative radiographic data from digitized conventional radiogram comparing those obtained from conventional radiogram. 112 conventional radiograms were evaluated using grading of trabeculation density. The same radiograms then digitized to obtain the quantitative numeric data of trabeculation density. The result showed that each grade from conventional radiogram has a range of numeric value in the digitized radiogram. This result could provide higher accuracy of trabeculation density analysis than the value obtained by using human eyes that will be beneficial for the dentist, especially prosthodontist in Indonesia.

Latar Belakang : Platelet Rich Plasma (PRP) telah dilaporkan memiliki efek positif pada regenerasi tulang, serta pada penyembuhan jaringan. PRP telah dianggap sebagai sumber autogenous dari faktor pertumbuhan terkonsentrasi yang dapat digunakan secara klinis untuk meningkatkan penyembuhan luka. Namun, kontroversi mengenai manfaatnya dalam regenerasi tulang. Dengan demikian, penelitian ini bertujuan untuk mengevaluasi pengaruh PRP terhadap pembentukan tulang pada fraktur mandibula. Efek PRP pada graft tulang adalah masalah yang menguntungkan. Telah dilaporkan bahwa PRP memperbaiki regenerasi tulang dalam graft tulang. Kematangan graft tulang dikombinasikan dengan PRP secara signifikan lebih besar dari tanpa PRP. Graft tulang yang dikombinasikan dengan PRP menunjukkan sistem Harversian yang matang dan proporsi lamelar yang lebih besar dan menghasilkan stabilitas hasil pemasangan graft tulang yang lebih superior. Digunakan pemindaian CBCT untuk memperkirakan proses penyembuhan tulang pada garis fraktur karena teknik ini dianggap sebagai salah satu teknik yang akurat, dapat direproduksi, dan noninvasif untuk mengukur kepadatan tulang. Tujuan : Mengetahui pengaruh penambahan Platelet Rich Plasma pada autogenous bonegraft terhadap densitas tulang (studi pada Ovis aries sebagai model manusia). Material dan Metode : Penelitian metode eksperimental analitik ini dilakukan untuk mengetahui pengaruh penambahan Platelet Rich Plasma pada autogenous bonegraft terhadap densitas tulang (studi pada Ovis aries sebagai model manusia). Kesimpulan : Tidak terdapat pengaruh penambahan Platelet Rich Plasma pada autogenous bonegraft terhadap densitas tulang (studi pada Ovis aries sebagai model manusia) pada periode waktu 3 minggu dan 6 minggu antara kelompok yang diberikan PRP dan kelompok yang tidak diberikan PRP. Pada analisis sampel Non PRP 3 minggu dengan Non PRP 6 minggu terdapat perbedaan walaupun secara statistik tidak terdapat perbedaan signifikan antara rerata PRP dan non PRP pada 3 minggu dan 6 minggu dengan nilai p> 0,05. ......Background : Although advances in understanding of peripheral nerve injury and regeneration and advances in surgical technique continue to be produced, successful results cannot be guaranteed after reconstructive surgery. Platelet Rich Plasma (PRP) has been reported to have a positive effect on nerve regeneration, as well as on tissue healing. PRP has been considered an autologous source of concentrated growth factors that can be used clinically to improve wound healing. However, controversy still exists regarding its benefits in bone regeneration. Thus, this study aimed to evaluate the effect of PRP on bone formation in mandibular fractures. The effect of PRP on bonegraft is a beneficial issue. It has been reported that PRP improved bone regeneration in bonegrafts, also that the maturity of bonegraft combined with PRP was significantly greater than that without PRP, and that bonegraft combined with PRP showed a mature Harversian system and a larger proportion of lamellar, resulting in stability of the results. placement of a superior bonegraft. CBCT scans are used to estimate the bone healing process at the fracture line as it is considered one of the most accurate, reproducible, and noninvasive techniques for measuring bone density. Aim: To determine the effect of Platelet Rich Plasma (PRP) mixed with autogenous bonegraft on bone density in sheep (Ovis aries). Materials and Methods: This analytical experimental research method was conducted to determine the effect of Platelet Rich Plasma (PRP) mixed with autogenous bonegraft on the total bone density in sheep (Ovis aries). Conclusion: The addition of Platelet Rich Plasma (PRP) mixed with autogenous bonegraft had no effect on the increase in bone density at 3 weeks after bonegraft application and there was no difference in bone density between the groups that were given PRP and the groups that were not given PRP. In the sample analysis of Non PRP 3 weeks with Non PRP 6 weeks there is a difference even though it was no statistically significant difference between the mean PRP and non-PRP at 3 weeks and 6 weeks with p value> 0.05

Osteoporosis is a silent disease, i.e. the disease will progress without symptoms or pain until bones start to break. Densitometry examinations to diagnose osteoporosis is relatively expensive for most people in Indonesia. Kusdhany et al have produced a mandibular density index specific for Deutero-Malay postmenopausal women (POSTUR-P). This index can be used to predict osteoporosis risk in mandibular and other bones. The objective of this research was to try out POSTUR-P before using it in the community. The study was a diagnostic test, on 31 Teratai clinic postmenopausal patients of Ciptomangunkusumo Hospital between 50-75 years of age from June to October 2014 and fulfilling inclusion criteria. Densitometry on lumbal and femur bones was used as a gold standard. The result of this study showed that POSTUR-P has high sensitivity and moderate specificity, and appears to be a good screening tool to indicate osteoporosis cases.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 329-332. Some researchers stated that osteoporosis in other bones will also be accompanied by a decrease in mandibular bone density. So that several risk factors for osteoporosis in other bones will also become risk factors for mandibular bone osteoporosis. Calcium intake, body mass index, and estrogen level were risk factors analyzed in this study. Mandibular bone density is important to maintain because of its relation with loss of teeth and success rate of prosthodontic treatment. The study design was unmatched case control. The subjects were taken from 226 postmenopausal women between 50-75 years of age, who fulfill the inclusion. One hundred and nine subjects with normal mandibular bone density categorized as cases and 117 subjects with mandibular bone osteoporosis categorized as controls. Mandibular bone density was analyzed using intra oral periapical radiograph. The result of this study showed that calcium intake was the main protecting factors for mandibular bone osteoporosis (OR=3,789), followed by body mass index (OR=2,184), and estrogen level (OR=1,017).
