Various studies are carried out for assessment of condylar bony changes in temporomandibular Disorder (TMD) using many imaging modalities like Orthopantomogram (OPG), Computed Tomography (CT) and cone beam computed tomography (CBCT) .

Although TMD is a disease of multifactorial origin, some studies have shown that these conditions are associated with anxiety, depression, oral parafunctional habits like bruxism, poor socioeconomic status and genetic factors. The incidence of condylar bony changes

in TMJ is more frequent with increase in age. Remodeling is a adaptive response of cartilage and osseous tissue to forces applied to the joint that may be excessive .

some studies had suggested that condylar  remodeling was age related. Whereas with the association of parafunctional habits like bruxism, the deterioration of osseous component of condyle will occur in younger age. This results in degenerative osseous changes like flattening, resorption, sclerosis, erosion, osteophyte and ely’s cyst. These remodeling were precursor to Temporomandibular joint Disorder(TMD).

 Previous studies have employed the conventional two dimensional imaging modalities like OPG, and other extraoral radiographs like reverse townes, transpharyngeal ,transorbital with advancing technology, CBCT provides a three dimensional view of TMJ in all aspects and is more reliable to assess the osseous changes.

 Thus our study aims to assess the correlation between  bruxism and incidence of osseous changes in condyle of both symptomatic and asymptomatic TMJ patients.  This can help in controlling the progression of the disease by timely management.
