This study aimed to evaluate the correlation between the Osteoporosis Self-Assessment Tool for Asians (OSTA) and three panoramic indices in relation to z-score and t-score values using quantitative ultrasound (QUS) bone densitometry. The sensitivity, specificity, and area under the curve (AUC) of the OSTA index were also measured using the QUS tool to evaluate the method’s performance in identifying people at risk of osteoporosis. The study employed a cross-sectional design with 387 participants (190 men, 197 women). Patients’ mandibular cortical indexes (MCI), mandibular cortical widths (MCW), and panoramic mandibular indexes (PMI) were measured from panoramic images. The sensitivity, specificity, and AUC were calculated using an OSTA index cutoff of ≤−1 and a t-score of ≤−1.0 for the QUS bone densitometry. The coefficient correlation of the OSTA index with the z-score (r = −0.563, p < 0.001) and t-score (r = −0.740, p < 0.001) shows a higher value than the MCI, MCW, and PMI, per the QUS. The sensitivity, specificity, and AUC values with a cutoff t-score of ≤−1.0 per the QUS in men was 90%, 50%, and 0.812, and in women, 96.8%, 30%, and 0.862. The OSTA index is a simple method that can be used in general dental practice.
Cleidocranial dysplasia (CCD) merupakan kelainan herediter yang mempengaruhi tulang dan gigi serta diwariskan secara autosomal. Meskipun radiograf dua dimensi dapat memberikan informasi diagnosis CCD, namun memiliki keterbatasan distorsi geometrik dan superimposisi. Laporan kasus ini memaparkan dua kasus CCD yang berbeda dan mengevaluasi gambaran radiograf dengan menggunakan modalitas pencitraan Cone-Beam Computed Tomography (CBCT) dengan tujuan untuk memberikan gambaran radiografis lengkap melalui CBCT sebagai salah satu alatpenunjang diagnosis yang memberikan rekonstruksi akurat, sehingga diharapkan dapat membantu dalam menegakkan diagnosis dan menentukan rencana perawatan. Dua orang pasien berusia dua belas dan sembilan tahun dikonsultasikan dari bagian Ilmu Kedokteran Gigi Anak untuk melakukan pemeriksaan pencitraan 3D CBCT. Temuan radiografik gigi multiple supernumerary di rahang atas dan bawah serta keterlambatan pertumbuhan gigi-gigi permanen pada kedua pasien, serta adanya kelainan tumbuh kembah pada struktur kranium, tulang-tulang wajah, maksila dan mandibula. CBCT mengatasi kelemahan atau kekurangan pada radiograf dua dimensi, khususnya evaluasi dalam arah bukolingual. Pencitraan 3D CBCT memungkinkan rekonstruksi yang akurat dan dari beberapa pandangan sagital, koronal dan aksial dari gigi supernumerari sehingga dapat dengan tepat menentukan jumlah, posisi, morfologi mahkota dan juga hubungannya dengan gigi permanen yang berdekatan sehingga memudahkan dalam menentukan rencana perawatan.
Background The purpose of this study was to investigate the association between the severity of the mandibular inferior cortex (MIC) porosity and the number of remaining teeth in elderly Indonesian people.Materials and methods This cross-sectional study was conducted by measuring secondary data on panoramic digital examinations of patients aged 50 years and older. A total of 428 panoramic radiographs were measured from January 2017 to December 2018. The number of remaining teeth (including the third molars) was evaluated. Mandibular porosity was measured by using panoramic radiographs, according to the MIC classification: normal; mildly to moderately eroded; and severely eroded cortex.Statistical analysis used Data analysis was done using Mann-Whitney nonparametric tests to verify the relationship between the MIC classification and the number of remaining teeth. Multiple linear regression analysis was performed to investigate the relationship between confounding variables.Results A significant correlation was found between MIC classification and the number of remaining teeth on the Mann-Whitney test (P < 0.001). Multiple linear regression analysis showed that MIC classification was significantly associated with the value of the number of remaining teeth after controlling for gender and age (β = -0.37, R2 = 0.22, P < 0.001). Subjects with MIC class 3 were 7.14 times more likely to lose their teeth than subjects with MIC class 1 or class 2.Conclusions Our study demonstrated that there was an association between the severity of mandibular inferior cortex porosity and the number of remaining teeth in elderly Indonesian people.
Objectives: The severity of jawbone atrophy differs among individuals and even within an individual. This study investigated the relationship between vertical mandibular bone atrophy and the number of remaining teeth in elderly Indonesian individuals. Material and methods: A total of 148 panoramic radiographs of patients aged ≥ 50 years were selected from dental records at the Radiology Department, Dental Hospital Faculty of Dentistry, Universitas Indonesia, in 2017. To measure vertical mandibular bone atrophy, a vertical line was created running from the crest of the alveolar ridge to the most inferior point of the mandibular inferior cortex through the center of the mental foramen. Subjects were first divided into four groups based on the number of remaining teeth: group I had 1-8 remaining teeth, group II had 9-16, group III had 17-24, and group IV had 25-32. Results: The number of remaining teeth was significantly associated with vertical mandibular bone atrophy. Mean differences and standard deviations for vertical mandibular bone atrophy were significantly higher in groups III and IV patients than in group I and II patients (group I vs. group III: 5.2 ± 1.7, p = 0.016; group I vs. group IV: 5.8 ± 1.6, p = 0.005; group II vs. group III: 3.2 ± 1.1, p = 0.023; and group II vs. group IV: 3.8 ± 1.1, p = 0.003). Patients with fewer remaining teeth were 1.78 times more at risk for a decrease in their mandibular bone volume than those with more remaining teeth. Males were 1.78 times more likely to have a higher mandibular bone volume than females. Conclusion: Mandibular bone atrophy was significant in patients with fewer than half of the total number of teeth remaining.
