Mandibular Angle Bone Apposition as a Radiological Indicator of Bruxism in the Chengalpattu Population: A Retrospective Study

Abstract

Background: Bruxism, characterized by the involuntary grinding or clenching of teeth, can lead to various complications, including dental wear, temporomandibular joint disorders, and changes in mandibular bone structure. One potential radiological indicator of bruxism is mandibular angle bone apposition, observed through panoramic radiography. Previous studies have suggested that alterations in the mandibular angle may be associated with bruxism, but research in specific populations remains limited.

Objectives: This study aims to evaluate the relationship between mandibular angle bone apposition and bruxism. By assessing panoramic radiographs, the study seeks to establish whether changes in bone apposition at the mandibular angle can be considered a reliable radiological marker for bruxism.

Methods: A retrospective analysis of panoramic radiographs from 300 participants, including 150 diagnosed bruxism patients and 150 controls, was conducted. The degree of mandibular angle bone apposition was classified as Grade 0 to 3 in both bruxism and control groups.

Results: In the bruxism group, 17.67% of participants exhibited no apposition (GRADE 0), 32.33% had mild apposition (GRADE 1), 30% showed moderate apposition (GRADE 2), and 20% displayed severe apposition (GRADE 3). Statistical analysis (p < 0.0001) confirms significant bone changes in individuals with bruxism, highlighting the potential of panoramic radiography for detecting these structural alterations.

Conclusions: This study highlights mandibular angle bone apposition as a potential diagnostic marker for bruxism, with the bruxism group showing higher frequencies of severe changes, supporting panoramic radiographs for early detection and intervention.
