Impact of bruxism on craniomandibular morphology: A cone-beam computed tomographic study.
Objective: The main goal of this work was to address craniomorphological characteristics of patients with bruxism when compared to those without bruxism using cone beam computed tomography (CBCT) imaging.
Methods: Seventy CBCT images of an equal number (n = 35) of orthodontic patients with and without bruxism (age range, 18-44 years) were retrospectively analyzed. Sagittal evaluation, mandibular shape, and skeletal asymmetry were systematically assessed in both groups.
Results: Significant differences (p < 0.05) were observed between groups for Right Articular Fossa (AF) - Axial Plane (AP) and Left AF - AP (B > NB), Right Gonial Angle (GA), Left GA, Sella-Nasion and Occlusal Plane (B < NB). Age (13%), Condyle-Gonion (18%), AF to AP (67%), and Mental-AP (16%) had the greatest impact on bruxers.
Conclusion: In this study, the CBCT 3D image showed significant differences in craniofacial morphology, particularly in the mandibular structure of bruxers compared with non-bruxers.
期刊介绍：
CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians.
CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest.
CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
