Aims: Though use of transcutaneous electrical nerve stimulation (TENS) in dentistry was first described in 1967 by Shane and Kessler, it has yet to gain widespread acceptance in dentistry. This study was designed to evaluate and compare the effectiveness of active and placebo TENS therapies in the treatment of temporomandibular disorder.Methods: Thirty patients received active TENS therapy and 15 received placebo TENS therapy. VAS was used to measure changes in pain and tenderness in the muscles of mastication and TMJs during and after therapy. Also, changes in mouth opening was recorded and analyzed.Results: A significant improvement was observed in both active and placebo TENS therapies regarding orofacial pain, muscles and TMJs tenderness and interincisal distance. None of the parameters except medial pterygoid muscle tenderness revealed any differences between the methods. Conclusion:This study justifies the use of TENS therapy as well as placebo in the management of TMD. TENS therapy appears to be useful in relieving pain, especially muscular and chronic pain. Hence, along with TENS therapy, placebo should also be considered as a potent and independent therapeutic modality in its own right.

This study suggests that the placebo can give near similar results as diazepam can. So the role of placebo should also be considered as one of the important management strategies. In the short term, reduction in the masticatory muscle tenderness and significant improvement in the mouth opening in both the groups were observed.

Adenomatoid odontogenic tumor (AOT) is a benign lesion derived from the complex system of dental lamina or its remnant. It is categorized into three variants (follicular, extrafollicular, and peripheral). We present a rare case of AOT arising from a dentigerous cyst around the unerupted canine in a 28-year-old female. We believe that this case z an odontogenic cyst with neoplastic development, containing both epithelial and mesenchymal components. As more cases accumulate, we will be able to study these rare lesions further whether the AOTs derived from an odontogenic cyst could represent a distinct “hybrid” variant separate to the three variants described thus far.

Fibrous dysplasia is a disturbance of bone metabolism that is classified as a benign fibro-osseous lesion. Fibrous connective tissue containing abnormal bone, replaces normal bone. The etiology of fibrous dysplasia is unknown. The radiographic appearance of the irregularly shaped trabeculae aids in the differential diagnosis. Occurring most commonly in the second decade of life, the lesions of fibrous dysplasia can be surgically recontoured for esthetic or functional purposes once they become dormant.
