Optical Coherence Tomography; A Modern Technique to Detect Oral Mucosal Lesion: A Review.

Early detection and management of potentially malignant oral lesions can significantly reduce progression of these lesions into invasive cancer, and would thus reduce morbidity and fatality rate. Cancerous and potentially malignant lesions show dysplastic feature which is mostly detected by biopsy. However, biopsy has a certain constraints like (i) biopsy can cause delay in the result, (ii) experienced pathologist must expound the biopsy sample (iii) sometimes can cause spread of cancer cells, (iv) cannot be done repeatedly. Therefore, in potentially malignant lesions and cancer optical coherence tomography (OCT) is utilized to detect early dysplastic changes. Therefore, we are presenting a review on the applications of OCT in oral mucosal lesions.

Temporomandibular Joint Manifestations in Rheumatoid Arthritis: A Case Report.

Rheumatoid arthritis (RA) is a chronic infl ammatory disease characterized by joint swelling, joint tenderness, and ravagement of synovial joints, leading to rigorous incapacitation, and premature mortality. It was fi rst described by Dr. Augustin Jacob Landr´e-Beauvais in 1800. RA aff ects about 1% population worldwide. Temporomandibular joint (TMJ) involvement is usually found along with the involvement of the joints of the hands and feet. TMJ involvement is associated with pain, infl ammation, limited joint movements, swelling, joint stiff ness, and muscle spasm. Radiological features include cortical erosion, decreased joint space, de-ossifi cation, sharpen pencil head or spiked deformity or mouthpiece of fl ute deformity of the condylar head. Clinical examination and investigations (radiographic and hematological) remain the mainstay of diagnosis. Here, we present a case of RA of TMJ along the joints of the hands and feet.
