Evaluation of panoramic radiomorphometric indices in Indian population

Objecitves: Radiomorphometric indices on dental radiographs can be used for screening of osteoporosis. However population-specific normative data is sparse. Aim was to establish radiomorphometric indices in Indian population and to determine role of age, gender and dentition on these indices. Materials and Methods: Cross sectional study was undertaken from January 2010 to December 2010. OPGs of 80 samples were divided into four age groups. Mental index, panoramic mandibular index, mandibular cortical index, antegonial index were measured. Relationships with age and dentition were analysed using Statistical Package for the Social Sciences SPSS12.0. Student t-test, one way analysis of variance, Chi square test was used to find the statistical significance. P value < 0.05 was considered to be significant. Results: In most of the study population endosteal margins of the mandibular cortex were even and sharp on both sides i.e.C1 appearance except in 60-69 years females who showed increased tendency of lacunar cortical defects i.e. C2 appearance. No correlation between dentition and mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) & Antegonial index (AI) (p value 0.583, 0.059, 0.491 respectively). Population’s mean of AI, MI, and PMI among males were 3.33, 3.97, 0.33 respectively and among females were 3.06, 3.64, and 0.32 respectively. (p value for AI, MI, PMI were 0.048, 0.028,0.037 respectively). Conclusions: All indices negatively correlated with age. There was a general downward trend with age until sixth decade, when values declined sharply. No statistical significance was found between AI, MI, and PMI and dentition

An Upper Lip Swelling: A Case Report, Differential Diagnosis and Review of Literature

Pleomorphic adenoma is the most common tumor of the salivary glands. About 90% of these tumors occur in the parotid gland and 10% in the minor salivary glands. The most common site for pleomorphic adenoma of the minor salivary glands is the palate followed by upper lip. Surgical removal with adequate margins is the principal treatment. Due to its microscopicprojections, this tumor requires a wide resection to avoid recurrence. We report a case of pleomorphic adenoma in the upper lip of an elderly female with emphasis on differentialdiagnosis and relevant review of literature
