Ameloblastic Fibro-Odontoma: A Journey of Progression?

A 19-year-old male patient reported to dental OPD of our institution with a swelling in the posterior part of the mandible on the left side. The patient gave a history of gradual increase in the size of swelling for 7 years. The patient also had a radiograph and histopathology slides from his previous dental visit at another facility.

Odontoameloblastoma: A report of a rare case.

Odontoameloblastoma (OA) is an uncommon mixed odontogenic tumor that contains an ameloblastomatous component and odontoma-like elements, usually seen to occur in the mandible of younger patients. Radiographically, the tumor shows central destruction of bone with extension of cortical plates and calcified structures which have the radiopacity of tooth structure. These may resemble miniature teeth similar to a compound odontoma or occur as large masses of calcified material similar to a complex odontoma.

Modified Cajal's trichrome stain as a diagnostic aid in the study of epithelial pathology.

Background: Diagnosis of initial epithelial pathology maybe difficult in Squamous Cell Carcinoma (SCC), Carcinoma In Situ and other atypical epithelial malignancies, under routine Haematoxylin and Eosin (H and E) stain. The detection of minor basement membrane alterations in doubtful cases is both time consuming and confusing.

Aims: To evaluate efficacy of Modified Cajal's Trichrome Stain (CTS) in relation to Haematoxylin and Eosin for study of epithelial dysplasia, carcinoma in situ, micro invasive SCC, frank SCC, and SCC in lymph nodes.

Expression of MUC1 mucin in potentially malignant disorders, oral squamous cell carcinoma and normal oral mucosa: An immunohistochemical study.

Background: Mucins alteration in glycosylation is associated with the development and progression of malignant diseases. Therefore, mucins are used as valuable markers to distinguish normal and disease conditions. Many studies on MUC1 expression have been conducted on variety of neoplastic lesions other than head and neck region.

Expression of human telomerase reverse transcriptase protein in oral epithelial dysplasia and oral squamous cell carcinoma: An immunohistochemical study.

Background: Telomerase is an RNA-dependent DNA polymerase that synthesizes TTAGGG telomeric DNA sequences and almost universally provides the molecular basis for unlimited proliferative potential. The telomeres become shorter with each cycle of replication and reach a critical limit; most cells die or enter stage of replicative senescence. Telomere length maintenance by telomerase is required for all the cells that exhibit limitless replicative potential.

Oral carriage of enterobacteriaceae among school children with chronic nail-biting habit.

Context: Onychophagia or habitual nail-biting is widespread among children and adolescents, between 10 and 18 years. Prevalence estimates range from 30% during childhood to 45% in adolescence. Nail-biting habit can result in autoinoculation of pathogens and transmission of infection between body parts.

Evaluation and comparison of decalcification agents on the human teeth.

Context: In routine histopathology, decalcification of bone and teeth is often an essential and important step during tissue processing. Various decalcifying agents have been used in the past. The rate of decalcification and the effect of decalcifying agents on the tissue and its staining characteristics are two important parameters which influence the selection of decalcifying solutions.

Florid cemento osseous dysplasia in association with dentigerous cyst.

We present a case of florid cemento-osseous dysplasia occurring in a 20-year-old Indian woman. The subject presented with three lesions involving the maxillary right quadrant, maxillary left quadrant and mandibular left quadrant. The mandibular left quadrant also demonstrated a cyst.
