Florid cement-osseous dysplasia of maxilla and mandible: a rare clinical case

Cemento-osseous dysplasia is a group of disorders known to originate from periodontal ligament tissues. Florid cemento-osseous dysplasia clearly appears to be a form of bone and/or cementoid tissues restricted to jaw bones. This lesion is usually asymptomatic and is incidentally detected during routine radiographic examination. The diagnosis is made by clinical and radiographic examinations, and biopsy is not necessary. The patient must manifest the typical changes in atleast two quadrants. An asymptomatic individual requires only a periodic follow-up to ensure that there is no change in the disease behavior. Surgical management is indicated only for a progressive lesion that produces orofacial disfigurement. This paper presents a rare case of a 60-year-oldfemale who was clinically and radiographically diagnosed as having florid cemento-osseous dysplasia in the maxilla and mandible. Discussion is presented with emphasis on clinical and radiographic manifestations.

Radiographic analysis of ameloblastoma: a retrospective study.

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.

Proposed clinical classification for oral submucous fibrosis.

Oral Submucous Fibrosis (OSMF) is a chronic, progressive, scarring disease, that predominantly affects people of South Asia and South-East Asia, where chewing of arecanut and its commercial preparation is high. Presence of fibrous bands is the main characteristic feature of OSMF. Based on clinical and/or histopathological features of OSMF, various classifications have been put forth till date. But the advantages and drawbacks of these classification supersedes each other, leading to perplexity. Our various studies and clinical experience in the field of OSMF have initiated us to propose/introduce the new clinical classification which could assist the clinician in the categorization of this potentially malignant disorder according to its biological behaviour and hence its subsequent medical and surgical management.
