A new perspective for radiologic findings of bruxism on dental panoramic radiography

Objective This study aims to evaluate whether there is a relationship between the appositional classification in the mandible angle region and the mandibular cortical index (MCI) seen in bruxist individuals and to differentiate between the bruxist group without mandibular apposition and the non-bruxist group on panoramic radiographs. Methods The mandible angle region of 209 individuals, 170 bruxists and 39 non-bruxists, were included in the study. Each mandible angle apposition was classified as G0 (No directional change, no bone apposition)—G1 (Directional change on the basal cortex. No bone apposition)—G2 (Directional change plus generalized bone apposition with inhomogeneous surface)—G3 (Directional change plus localized bone apposition at one or more sites). The MCI of each individual was recorded according to their classified apposition. Results No statistically significant difference was found in the relationship between MCI and apposition severity in mandible angle grades in bruxist individuals ( p = 0.063). A statistically significant difference was found between MCI and the bruxist G0/non-bruxist G0 groups ( p
