ABSTRACT
Distomolars are supernumerary teeth present distal to third molars. Although many cases of bilateral fourth molars are reported, very few cases having bilateral fifth molars are described in literature. Here, we present a case having bilateral impacted maxillary fourth and fifth molars with the fifth molar on the left side having an unusually small appearance.
ABSTRACT
Herpes zoster is a disease of adulthood caused by reactivation of varicella zoster virus which lies dormant in sensory ganglia. Immunocompromised patients i.e. with malignancy/organ transplantation/AIDS; patients taking immunosuppressive drugs are more susceptible for herpes zoster infection. Various prodromal features like pain, odontalgia, fever and regional lymphadenopathy precede the active lesions of herpes zoster- i.e. unilateral vesicles (cutaneous/oral) and ulcerations follows pathway of dermatome and this clinical appearance is sufficiently distinctive to make clinical diagnosis of herpes zoster accurately without any other investigations. Antiviral drugs e.g. Acyclovir, Famcyclovir and Valacyclovir with symptomatic treatment are treatment of choice for herpes zoster infection.
ABSTRACT
Background: Ameloblastoma is benign odontogenic tumor, usually affecting the posterior region of mandible. It is seen in the third to fifth decades of life. Radiographically the lesion is variable in appearance and may be unilocular or multilocular, with well-defined cortical borders in the mandible and ill-defined margins in the maxilla. Objective: To analyze cases of ameloblastoma, with emphasis on the radiographic findings. We also review the current literature briefly and discuss the clinical and radiographic findings. Materials and Methods: The present hospital-based retrospective study was conducted by reviewing the clinical and radiographic records of ameloblastoma cases from 2009 to 2011, available in the archives of the department. The data of a total of 14 patients were analyzed. Results: We observed that the patients affected with ameloblastoma were in the age-group of 19-68 years. The male: female ratio was 1.3:1. The mandible (78.57%) was more commonly affected than the maxilla (14.28%). Six patients (42.86%) had unilateral involvement and eight cases (57.14%) had bilateral involvement. The multilocular and unilocular types of ameloblastoma were noted in 12 (85.72%) and 2 cases (14.28%), respectively. The soap-bubble (50.00%), spider-web (21.43%), and honeycomb (14.28%) appearances were seen in the multilocular variety. Root resorption of variable degree was distinctly observed in 11 cases (78.57%). Conclusion: Radiographs are an important aid for the diagnosis of oral lesions of various types, especially those that involve bone. It is important for the practicing clinicians to know the salient features of ameloblastoma which are peculiar to the local population.
ABSTRACT
Cemento-ossifying fibromas (COFs) are benign lesions affecting the jaws and other craniofacial bones. They commonly affect adult females between the third and fourth decade of life, predominantly occurring in the premolar/molar region of the mandible. Most of the lesions typically show slow and often expansile growth, centrally within the jaw and characteristically behave in a benign form, but occasionally they may present as an aggressive gigantiform lesion. Radiographically, they appear as well-defined unilocular or multilocular intraosseous masses. The lesion is invariably encapsulated and of mixed radiolucent densities. The tumor may grow quite extensively; thus, the term "aggressive" is sometimes applied. Surgical resection is the treatment of choice. They are insensitive to radiotherapy and recurrences are uncommon. Clinical, radiographic and histopathologic features of COF and other fibro-osseous lesions are overlapping and may cause confusion in classification, diagnosis and treatment.
