Assessment of Maximum Bite Force in Oral Submucous Fibrosis Patients: A Preliminary Study

Abstract Objective: To determine the maximum bite force (MBF) in oral submucous fibrosis (OSMF) patients and to compare them with that of healthy subjects. Material and Methods: Twenty patients who were clinically confirmed, as OSMF and 20 healthy controls matched for age, gender, and number of intact functional teeth were included in this study. For each subject, age, gender, weight, height and body mass index (BMI) were recorded. The MBF registration was carried out by the two evaluators, who were previously calibrated. Bite force was measured in the first molar region using a force transducer occlusal force meter for each subject seated at the upright position, with Frankfort's plane nearly parallel to the floor, and no head support. The Student's independent t-test was used to determine the statistical significance in relation to mean height, weight, BMI and the presence of number of intact teeth and MBF between the healthy subjects and OSMF individuals. A comparison of grades of OSMF with all variables was carried out by one-way ANOVA test. Results: No significant difference was found in mean age, mean height, weight, BMI and the presence of the number of intact teeth between healthy individuals and OSMF patients. The mean MBF in healthy subjects was 628.23 ± 24.39 N and 635.47 ± 31.22 N in OSMF patients. Even though the healthy subjects reported a higher MBF than OSMF patients did, the difference was statistically non-significant. With regards to sides, no significant difference was observed in mean MBF in healthy subjects and OSMF patients on the right (p=0.7818) and left side (p=0.6154). Conclusion: The healthy subjects reported higher MBF values than OSMF patients did and the difference was statistically non-significant.

Complex odontoma: report of two unusual cases

Odontomas are the most common benign, slow-growing and nonaggressive odontogenic tumors of the jaws. They are usually clinically asymptomatic and are diagnosed on routine radiological examination in the second decade of life. The eruption and infection of odontomas are uncommon and very few cases are reported in the literature. This paper reports two cases of complex odontomas with such unusual features.

Ectodermal dysplasia : report of a rare case.

Ectodermal Dysplasia (ED) is a hereditary congenital disorder of ectodermal origin. It is characterized by lack of sweat glands, (hypohydrosis), Alopecia (Hypotrichosis), defective palms and soles (Palmoplantar hyper keratosis) and oral presentation of partial absence of teeth, (hypodontia) or complete absence of teeth (anodontia). Hypodontia of primary and permanent dentition is one of the most frequently occurring oral symptoms in ectodermal Dysplasia. We report an unusual case of ectodermal dysplasia effecting soles and palms along with oral manifestations.

Florid cemento-osseous dysplasia: Review and report of two cases.

Only three Indian patients of florid cemento-osseous dysplasia have been reported (less than 2%), according to the review of recent literature (2003). This makes the occurrence of FCOD a relatively rare phenomenon. The age group may vary from 19-76 years and typically presents in the fourth and fifth decade. In most of the cases, patients do not have family history of the disease. We report two cases showing classic radiologic features. The diagnosis of our cases were made radiographically.
