Abstract

Introduction: Bruxism is associated with several etiological factors ranging from psychological, neuromuscular, and occlusal disharmonies. Occlusal disharmony includes premature contacts, drifting of teeth following extraction, uncontoured restorations and prosthesis, and varying forms of malocclusion. However, the contributory role of lower anterior crowding inducing bruxism needs to be studied in detail. Aim: This study aims to evaluate if there is any correlation between anteriorly crowded teeth and bruxism-related parafunctional habits. Materials and Methods: A total of 100 individuals were examined; intraoral photographs are taken to assess their crowded teeth. Individuals were categorized as 50 controls and 50 cases, with controls as those without bruxism and cases of those individuals having bruxism. The number of people in each category having anterior crowding was estimated to determine correlation. The data obtained were tabulated and correlation coefficient was calculated using the Spearman’s method. Results: Thirty-eight patients had bruxism along with anterior crowding. Twelve patients had bruxism, but anterior crowding was not present. Sixteen patients had anteriorly crowded teeth but in the absence of bruxism. Thirty-four patients neither had bruxism nor anterior crowding. Spearman correlation coefficient ρ = 0.441 was observed. Conclusion: The study revealed a positive correlation between anteriorly crowded teeth and bruxism-related parafunctional habits in the population studied.
