ABSTRACT
AIMS AND OBJECTIVES: (1) To determine the usefulness of mandibular ramus as an aid in sex determination. (2) To evaluate Anteroposterior | superioinferior angle of mandibular condyle. MATERIALS AND METHODS: A retrospective study was conducted using orthopantomographs of 60 males and 60 females, which were taken using Kodak 8000C Digital Panoramic and Cephalometric System (73 kVp, 12 mA, 13.9 s). The age group ranged between 18 - 45 years. Mandibular ramus measurements were carried out using Master View 3.0 software. The measurements of the mandibular ramus will be subjected to Discriminant function analysis. RESULTS: Maximum ramus breadth, Minimum ramus breadth, Condylar height, Projective height of ramus Coronoid height were calculated for both the sexes differently with the formula & analyzed with Discriminant function analysis using Fischer exact test. The P value was statistically significant with the P value < 0.05 for the following parameters Max. ramus breadth, Condylar height and Projective height of ramus. CONCLUSION: Mandibular ramus measurements can be a useful tool for gender determination.
ABSTRACT
Burning mouth syndrome (BMS) is multifactorial in origin which is typically characterized by burning and painful sensation in an oral cavity demonstrating clinically normal mucosa. Although the cause of BMS is not known, a complex association of biological and psychological factors has been identified, suggesting the existence of a multifactorial etiology. As the symptom of oral burning is seen in various pathological conditions, it is essential for a clinician to be aware of how to differentiate between symptom of oral burning and BMS. An interdisciplinary and systematic approach is required for better patient management. The purpose of this study was to provide the practitioner with an understanding of the local, systemic, and psychosocial factors which may be responsible for oral burning associated with BMS, and review of treatment modalities, therefore providing a foundation for diagnosis and treatment of BMS.
ABSTRACT
CONTEXT: Caries epidemiological studies based on clinical examination alone tend to underestimate proximal caries. AIMS: This study aims to determine the additional value of radiographic examination (bitewings) compared to clinical examination in assessing posterior proximal caries. It also aims to determine the radiographic multiplication/adjusting/correction factors by which a clinical decayed surface (D-S) and decayed-missing-filled surfaces (DMFS) score could be multiplied, to obtain an actual D-S and DMFS score. MATERIALS AND METHODS: Two groups of 100 subjects each, in the age range of 16-20 years, were examined clinically for caries and their DMFS index recorded. Both groups were subjected to bitewing radiographs to detect the clinically undiagnosed posterior proximal caries. The radiographic adjusting factors were determined for group A. To check its repeatability and thus its usefulness, radiographic correction factor was determined for Group B. STATISTICAL ANALYSIS: The results were statistically analyzed with the use of means, standard deviations, regression equation and "Z" test. Level of significance was determined at P > 0.05. RESULTS: A significant number of clinically undetected proximal caries was diagnosed with the help of bitewing radiographs. The difference between the radiographic adjusting/correction factor for D-S and DMFS score for the two groups was statistically not significant (P > 0.05) thus verifying the repeatability of the radiographic correction factors. CONCLUSION: The radiographic correction factors can be used to obtain a more precise estimate of true caries prevalence in a particular study population without having to subject all individuals to radiographic examination.
