Intraosseous clear cell mucoepidermoid carcinoma: A case report and evaluation.

Salivary gland tumours are relatively uncommon, and there exists a considerable diagnostic difficulty owing to their diverse histological features in individual lesions and the presence of a number of types and variants, in addition to overlapping histological patterns similar to those observed in different tumour entities. One such group of variations is clear cell tumours of oral cavity which constitute an assorted group of lesions that may be odontogenic or metastatic or of salivary gland origin. The clear cell variant of mucoepidermoid carcinoma is at times misleading to the clinician because of its atypical location and innocent appearance.

Ameloblastic carcinoma: A case report and evaluation.

Malignant odontogenic neoplasms are extremely challenging to study due to their rarity and variable clinical presentations. Ameloblastic carcinoma (AC) is one such odontogenic tumor which has been the subject of controversy, in part because of its scarcity, complicated by confusion in terminology along with complexity in classification. Histologic features of AC resemble tumor cells of ameloblastoma but exhibit cellular atypia.

Osteosarcoma: A case report and evaluation.

Osteosarcoma (OS) comprises 2.1% of all malignant oral and maxillofacial tumors. OS arising from the jaw OS differs from OS of the long bones in its biological behavior, presenting a lower incidence of metastasis and a better prognosis.

Evaluation of a case of diffuse large B-cell lymphoma.

Lymphomas are a group of malignant blood cell tumors that develop from lymphocytes representing 2.2% of all malignant neoplasms of the head and neck. Two main categories of lymphomas are Hodgkin's lymphoma and non-Hodgkin's lymphoma (NHL) of which 90% are of the NHL type.

Monocytoid B cell lymphoma: A case report and evaluation.

Lymphomas are a group of malignant blood cell tumors that develop from lymphocytes. Two main categories of lymphomas are Hodgkin and non-Hodgkin lymphomas (NHL), of which 90% are of the NHL type. The objectives of classifying is to help in the identification of homogenous group of well-defined entities and facilitating the recognition of uncommon diseases that further require classification as it affects prognosis and therapeutic implications.

Diagonal tooth measurements in sex assessment: A study on North Indian population.

Background: Sexual dimorphism has been of great interest to anthropologists and odontologists. Dental measurements are important in anthropology for the study of sexual dimorphism with most common being the traditional linear odontometric measurements. Apart from these, alternative dental measurements have been developed such as the crown and cervical diagonal diameters and mesiodistal and buccolingual cervical diameters of teeth.

Sex assessment by molar odontometrics in North Indian population.

Introduction: Human identification is based on scientific principles, mainly involving dental records, fingerprints, estimation of age, postmortem reports, differentiation by blood groups, and DNA comparisons. Sex assessment is one of the prime factors employed to assist with the identification of an individual.

Aims And Objective: To investigate univariate sex differences in the dimensions of permanent first molars and to assess sex, based on buccolingual (BL) and mesiodistal (MD) dimensions of permanent first molars in a population of north India.

Calcifying odontogenic cyst: dilemma in classification.

Calcifying odontogenic cyst (COC) shows extreme diversity in its clinical and histopathological features, as well as in its biological behavior. Because of this diversity, there has been confusion and disagreement on the terminology and classification of this lesion. Attempts to classify COC can be divided into two concepts: monistic and dualistic.

Intra-oral schwannoma- a case report.

Neurilemmoma (Schwannoma) is a benign tumour of neuroectodermal origin. It usually occurs as a asymptomatic, solitary, smooth-surfaced and slow growing lesion, emerging at any age, with as such, no gender prelidiction. Occurring as a common tumour in the head and neck region, its intraoral presentation is very rare.

Aggressive desmoplastic fibromatosis - a clinicians dilemma case report and review of literature.

Fibromatoses are a heterogeneous group of distinct entities which differ in biological behaviour, but arehistologically very similar. This group of fibrous tumor or tumor like lesions, present considerable difficulties in pathologic diagnosis. Aggressive fibromatosis (AF) of the oral or para-oral structures is a very uncommon finding and its intra-osseous component is even relatively unusual.

Dentigerous cyst of inflammatory origin-a diagnostic dilemma.

Odontogenic cysts commonly encountered in dental practice are the radicular cysts and dentigerous cysts. Apart from the developmental origin of dentigerous cysts, an inflammatory origin has also been suggested. It has been reported that inflammation progressing from the root apex of the deciduous tooth brings about development of the dentigerous cyst around the unerupted permanent tooth.
