Prevalence of Torus Mandibularis in the Local Population of Lahore, Pakistan

Objective: To determine the prevalence of Torus Mandibularis (TM) in the local population of Lahore, Pakistan. Methodology: A cross-sectional study with a non-probability convenient sampling technique was conducted at the Oral Diagnosis Department of Lahore Medical and Dental College over six months, from July 2023 to December 2023. The study included 158 participants who were examined for the presence or absence of mandibular tori. Clinical examination was conducted by visual inspection and palpation to identify unilateral or bilateral mandibular tori. The Igarashi Torus Index was utilized to classify the presence and severity of tori, with scores ranging from 0 to 3. A score of 0 indicated no detectable tori through either visual inspection or palpation; Class 1 indicated that tori could only be identified through palpation; Class 2 suggested that the tori were visibly prominent enough to create a distinct shadow; and Class 3 denoted that the contour of the tori could be traced visually around the base. Data were analyzed using SPSS version 26, with frequencies and percentages calculated to present the findings. Results: The prevalence of TM in the Lahore population was 17.7%, with females showing a higher prevalence (11.4%) than males (6.3%). TM occurrence was more frequent in individuals in their second and third decades. Conclusion: Mandibular tori were more frequently observed in females than males, and they were predominantly seen in younger adults in their twenties and thirties.
