Aim and objective To evaluate the possible genotoxic effect of X-rays on buccal mucosa while exposing to dental panoramic radiography using micronucleus test. Materials and methods The study group comprised of 30 healthy subjects, 15 males and 15 females, aged between 24 years and 65 years. Samples were obtained from the exfoliated oral mucosa cells of buccal mucosa before and 12 days after exposing the patients to panoramic radiography. Results The study reported that there was no significant increase in the number of micronuclei cells present before and after panoramic radiography. Positive correlation existed between age with pre- and postexposure micronuclei. Conclusion Diagnostic dental panoramic radiograph does not induce micronuclei in the target buccal epithelium cells. A positive correlation between age and micronuclei frequency was established. Clinical significance Panoramic radiographs does not induce cytotoxicity but increase frequency may be vulnerable to genotoxic effects in buccal mucosal cells. Hence, dental radiographs should be prescribed only when necessary. How to cite this article Santhosh K, Manzoor S, Sushanth A, et al.

Ankylosis of the temporomandibular joint (TMJ) involves fusion of the mandibular condyle to the base of the skull. Trauma and infection are the leading causes of ankylosis. The rst sign of a signicant problem may be increasing limitation of jaw opening, and it is usually not associated with pain. Early diagnosis and treatment are crucial if the worst sequelae of this condition are to be avoided. We present a case report of bilateral TMJ ankylosis in a 34-year-old female patient.

Odontogenic Keratocyst (OKC) is a clinico-pathologically distinct form of developmental odontogenic cyst. It is known for its aggressive biological behavior and high recurrence rate. Odontogenic keratocyst (OKC) is the third most common odontogenic cyst and comprises about 12% of all the cysts occurring in the maxillofacial region. OKC has a distinct feature to occur in body of the mandible and ramus. But it can also be found in the maxilla especially in the canine region. We present a rare case of OKC in maxillary sinus of a 35 year old female patient which is associated with ectopic third molar that can be easily confused with other lesions of maxillary sinus like sinusitis or antral polyps. Involvement of the maxillary sinus by OKC is rare with < 1% of cases reported in the literature.
