The commonest clinical conditions for imaging referral are the temporo-mandibular joint (TMJ) disorders or dysfunctions followed by pathologies specific to the bone and the joints. Various noninvasive and invasive imaging modalities are available to image TMJ. Application of C-arm technology to study the dynamics of TMJ is unique of its kind as this is the only modality where TMJ can be studied in motion. The basic objective of the study to evaluate the efficacy of c arm in measuring the range of dynamic movement.
This case control study was conducted among 35 cases having TMJ pathologies and 35 healthy controls in Department of oral medicine during April-December 2018. The inter-incisal distance and the condylar distance was measured using c arm.
The mean inter-incisal distance (controls: 46.5 ± 12.3 mm vs cases: 32.1 ± 10.9 mm) as well as mean condylar distance (controls: 16.8 ± 5.4 mm vs cases: 10.8 ± 3.9mm) were significantly lower amongst cases as compared to controls. The inter-incisal distance as well as the condylar distance was found to be significant between cases and controls amongst both the genders
The programming of c ram in dental use mostly in TMJ needs to evaluate with respect to adjusting the image clarity contrast sharpness and preventing the overlapping of the adjacent structures. In this study, we got a significant result when we compared the overall inter-incisal distance and condylar distance between healthy and diseased individuals.
