Chronic bruxism may impose excessive and abnormal mechanical loads on the temporomandibular joint (TMJ), potentially altering joint morphology and joint space dimensions. These changes can be subtle and asymptomatic initially, but they may progress to disorders such as disc displacement, joint pain, and functional limitations. Radiographic evaluation of TMJ space, particularly through advanced imaging modalities such as cone beam computed tomography (CBCT), offers a noninvasive means of quantifying joint space alterations. However, the relationship between bruxism and TMJ space narrowing or asymmetry remains inadequately understood, with inconsistent findings across existing literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To quantitatively evaluate the TMJ space in individuals with bruxism using CBCT and compare findings with matched nonbruxer controls.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A cross\u2010sectional study was conducted on 75 patients clinically diagnosed with bruxism (age 20\u201345 years, 36 males, 39 females).
