ABSTRACT
Background: Tobacco practice in relation with oral diseases is a foremost cause for the global oral disease burden and is accountable for up to 50% of all periodontitis cases among adults. The present cross-sectional study was undertaken to evaluate the local effects of various types of smokeless tobacco on periodontal health in tobacco pouch keratosis (TPK) patients in Mangalore city in the state of Karnataka. Materials and Methods: A total of 345 TPK patients were evaluated of which all were smokeless tobacco users. All the patients were clinically examined for different clinical periodontal parameters such as stains, gingival recession (GR), periodontal pocket, furcation involvement, and mobility and local effects of various types of smokeless tobacco on periodontal health in TPK sites were recorded. Results: The prevalence of GR was of 87.5%. Haathichaap was the most common smokeless tobacco used (35.9%) closely followed by nonpackaged type (loose tobacco) (19.4%). This was followed by Madhu (14.2%). Likewise, periodontal parameters were observed more in these patients in decreasing order. Conclusion: The results of the present study agree strongly with other smokeless tobacco user studies in terms of the strong association between GR and smokeless tobacco placement. The present cross-sectional study indicates that TPK lesions are positively associated with periodontal diseases. It is important to raise awareness of both oral cancer and periodontal risks and inform about its possible health consequences thereby working towards an improvement of oral and general health and related quality of life in these patients
ABSTRACT
Desmoplastic ameloblastoma (DA) exhibits important differences in gender, anatomic distribution, radiographic findings, and histologic appearance compared to other types of ameloblastoma. Radiologically, DA is seen either as ill-defined mass containing osteolytic and sclerotic areas or as multifocal radiodense flecks within radiolucent background resembling a honeycomb. The radiographic differential diagnosis includes fibro-osseous lesions such as cemento-ossifying fibroma, fibrous dysplasia, calcifying odontogenic cyst, and chronic sclerosing osteomyelitis. Thus, DA should primarily be included in the differential diagnosis of a mixed radiopaque-radiolucent lesion with diffuse borders in the anterior premolar region of the jaws. This report adds to the literature of mixed radiolucent-radiopaque lesions which may not always be histopathologically diagnosed as a fibro-osseous lesion but could turn out to be a DA. This report also benefits the dental community by cautioning them to be aware of DA that can be associated with multiple unerupted teeth which is quite a rare finding.
ABSTRACT
Nutrient canals are intra-osseous spaces or channels containing nerves and blood vessels. They are observed more frequently in the mandibular anterior region as radiolucent horizontal lines of varying widths, usually situated interproximally and inferiorly to the teeth. The aims of this investigation were to evaluate radiographically the presence of nutrient canals in 500 patients with periodontitis and 500 controls, to correlate their presence with severity of bone loss and trabecular bone pattern and to correlate the type of trabecular bone pattern to the age of the patient, bone loss and number of nutrient canals
ABSTRACT
Oral malignant melanoma is an infrequent neoplasm making up less than 1% of all melanomas; its behavior is more aggressive when compared to melanomas of the skin. We present a rare case of a 50-year-old male patient with a stage II oral malignant melanoma of the anterior mandibular gingiva treated with surgery and radiotherapy
ABSTRACT
Ewing's sarcoma of the jaw is a primitive malignant tumor of the bone. It is commonly seen in children and adolescents. Its occurrence in the head and neck region is unusual and generally involves most frequently the mandible rather than the maxilla. The present case discuss the clinical, diagnostic [radiographic, histopathologic] and therapeutic findings of an ES of the mandible in a 14-year-old boy. Early detection of such lesions is difficult because the signs and the symptoms do not appear until the lesion has progressed considerably. This case elucidates the importance of professional knowledge of the relevant aspects of malignant lesions such as Ewing's sarcoma
