To determine the accuracy of Pederson and Parant Scale for predicting the difficulty level of mandibular third molar extraction. Prospective cross-sectional, 6 months from January 2012 to June 2012. All consecutive patients who presented for the extraction of impacted third molars were included in the study. Orthopantomograms (OPGs) were advised and on these OPGs third molars were classified as easy, moderate or difficult according to standard Pederson scale. Similarly modified Parant scale was utilized to predict the difficulty of removal of third molars. Root pattern was also noted on the OPG. These parameters were then compared with peri-operative parameters like time taken for extraction and need for crown or root sectioning using Chi Square test. A p value of <0.05 was taken as significant. A total 50 patients were included in the study. Out of these 24 were males and 26 females with a male to female ratio of 1:1.08. The age ranged from 18-38 years with a mean of 26.32±5.43 years. The pre operative predictions for Pederson’s and Modified Parant’s Score were compared with per operative findings using Chi-Square test. The results were insignificant in terms of Pederson Scale (p value>0.05) while significant results were obtained in case of Parant Scale (p value<0.05). Statistically significant results were seen for root pattern and level of difficulty (p value<0.05). These scales failed to predict difficulty level of tooth removal accurately especially in cases of distoangular impactions. When combined with root pattern, the accuracy of prediction gets significantly better.

OBJECTIVES: The objective of the study was to evaluate the results of nasolabial/extended nasolabial flaps as a modality for treatment of oral submucous fibrosis. MATERIALS AND METHODS: Eleven patients of Stage III or IVa maximum interincisal opening were selected to be operated. Nasolabial/extended nasolabial flaps were done for both the sides. All of the flaps were done in a single stage and were inferiorly based. A similar flap harvest/surgical technique was utilized for all the cases. RESULTS: The preoperative mouth opening ranged from 5 to 16 mm, with a mean of 10.09 mm. At 6 months the mouth opening ranged from 29 to 39 mm. Some of the complications encountered were poor scar, wisdom tooth traumatising the flap, decreased mouth opening due to non compliance and too much bulk. All of theses were managed satisfactorily. CONCLUSION: The nasolabial flap is a very reliable flap to restore the function of oral cavity. Important adjuvant measures are habit cessation, lifestyle changes, and aggressive physiotherapy.
