Background:
Bruxism, the most common repetitive oral behavior, is reported widely in young adults due to excessive stress and sleep abnormalities. If left undiagnosed, it may cause pathologic alteration in condylar morphology.
Methods:
This Institutional Ethics Committee approved cross-sectional comparative study comprised of 100 patients, equally divided into groups. The study group diagnosed based on the self-reported questionnaire while control group patients were recruited retrospectively. The patients were evaluated using CBCT.
Results:
Flattening 26 (52%) and sclerosis 31 (62%) were more frequent in bruxers than non-bruxers (p < .05). Surface erosion 4 (8%) and osteophytes 14 (28%) were also noted in bruxers. Interestingly, non-bruxers also showed osteophytes 16 (32%) and surface erosion 9 (18%), which became the point to be focused on.
Conclusion:
Condylar alterations were more frequently observed in participants with possible bruxism. Prompt intervention can be inculcated to halt progress of the condition.
Trial Registration:
The study has been registered under Clinical trial registry - India (CTRI registration number: CTRI/2023/05/052782) on May 17, 2023.

01:10Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
