Morphology of the mandibular cortex on panoramic radiographs as an indicator of bone quality.

The alveolar process is the most supporting tooth containing trabeculae and has the highest metabolic rate in the mandibular body of post-menopausal women. The decreasing in estrogens level on post-menopausal women results a faster reaction than men for 2-3 times. This research aims to determine the bone quality based on trabeculae alveolar process analysis using panoramic radiographs. The research methodology was to conduct 67 samples of panoramic radiographs from RSGM Unpad. This research applied observational analytic methodology by taking cross-sectional data using secondary data on three groups of bone quality based on measurement using DEXA t-score (normal, osteopenia and osteoporosis). The panoramic radiograph data processing was conducted with Image J software by separating the background and foreground (trabeculae). A focus of 30x30 mm ROI in the alveolar distal portion of the left and right mandibular second premolar teeth, and calculation of trabecular area. Result: average of normal trabecular area: 82.35%, osteopenia: 73.9% and osteoporosis: 68.7% respectively. The difference between normal and osteoporosis was discovered, but no difference was found between normal and osteopenia with p <0.05. This research concludes that the region of interest trabecular of alveolar process with panoramic radiograph can be used to detect osteoporosis on post-menopausal women.

Background: People living with HIV may have several pathologic conditions in its body and bone is one of the organs affected by HIV infection. HIV-infected patients have been associated frequently with osteoporosis and lower bone mineral density (BMD) which may lead to the increasing risk of bone fracture. This situation may become more complicated in children and young age as it will affect the long-term bone quality and development later in life until the peak BMD is reached. Objectives: The aim of this study was to measure the mandibular bone quality using the mandibular cortical index (MCI) and panoramic mandibular index (PMI) in panoramic radiographs of HIV-infected children. Method: This study used descriptive cross sectional research design which analyzed panoramic radiographs of HIV-infected children and measured its mandibular bone quality. Total 43 panoramic radiographs of HIV-infected children were observed and analyzed qualitatively using mandibular cortical index (MCI) and panoramic mandibular index (PMI) were used for the quantitave measurement, as it have been widely used for assesing mandibular bone quality in previous studies. Mandibular cortical index (MCI) has 3 categories of cortical bone quality: C1 (normal cortex), C2 (mildly to moderately eroded cortex), and C3 (severely eroded cortex), while the normal ratio of mental foramen-inferior border of mandible to mandibular cortical length in panoramic mandibuIar index is about 0.3. Result: Mandibular cortical index (MCI) of 43 HIV-infected children consist of 4 samples in C1, 38 in C2, 1 in C3, while the panoramic mandibular index (PMI) of 43 HIV-infected children consist of 23 less than normal, 5 normal, 15 more than normal. Conclusions: The most number of mandibular cortical index (MCI) was C2 (mildly to moderately eroded cortex) and the most number of panoramic mandibular index (PMI) was less than normal of HIV-infected children.

Clinical Records

It is evident that hyperdontia is more common in the permanent dentition than in the primary. There is a considerable difference between males and females in the prevalence of these teeth in permanent dentition; hyperdontia is twice as common in males as in females. However, this approximation varies in terms of location, other associating syndromes that may be present, and the ethnicity of the individual. In terms of ethnicity, it can be seen that hyperdontia is in fact less common in Caucasian than in Asian populations. There is evidence to show that an individual is more likely to have hyperdontia if other members of their family also have the condition. Hence the present study was planned for evaluation of occurrence of hyperdontia in non-syndromic population from Bihar Region. The present study was planned in Public Health Dentistry, Patna Dental College and Hospital, Patna, Bihar. Total 195 patients referred to Department of Dentistry were evaluated in the present study. Panoramic radiographs and clinical records of patients above the age of 18 years and without any syndromic features were selected for the study. All the radiographs were examined for the presence of supernumerary teeth, their location, morphology, and number. Morphologically, teeth were classified as conical, tuberculate, supplemental, and odontoma. Early diagnosis of dental anomalies can prevent some esthetic, orthodontic, and periodontal problems, and knowledge of the prevalence and distribution of the anomalies may help clinicians to the detection of these anomalies at early stages. Our study evaluated the prevalence of selected dental anomalies; future studies should investigate the prevalence of dental anomalies of all types.
