Prevalence of Tertiary mandibularis and its association with para-functional activity in tertiary care centre in Shimla, H.P., India: A hospital based cross sectional study

Abstract

Introduction: Oral tori are bony growths present in oral cavity and are not considered as pathological lesions. Torus mandibularis (TM) is usually present in lingual aspect of alveolar process in canine-premolar region of mandible. The objective of the study is to determine the TM' prevalence among outpatients attending tertiary care center and its relevance with parafunctional activities. Materials and Methods: The study was conducted in the out patients attending the hospital between December 2017 and May 2019. Fourteen thousand and two hundred and eight patients were screened for the presence of TM as per inclusion and exclusion criteria. The data were collected and subjected to the statistical analysis. Results: Out of 14,208 patients, 157 patients were presented with TM. The prevalence found to be 1.1%. Tori were more frequent in males than females. The most commonly observed type was bilateral solitary type. The association of TM with parafunctional activities and temperomandibular disorder was found to be significant. The higher frequency of TM was seen in the subjects residing at high altitudes. Discussion: The prevalence of TM in our study was found to be low. The study was undertaken to record the preliminary data regarding TM in this region and its association with parafunctional activity. Conclusion: We suggest performing thorough clinical examination and imaging to rule out underlying parafunctional activity, if TM is incidental finding.
