Clear Cell Variant of Calcifying Epithelial Odontogenic Tumor: A Rare Clinical Entity.

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign odontogenic neoplasm of the jaws. Although clear cells have been reported in approximately 8% of cases of CEOT, the exact nature of these cells in clear cell calcifying epithelial odontogenic tumor (CCEOT) has not been elucidated. Presence of clear cells in CEOT may confer a more aggressive behavior to the lesion and a tendency for recurrence and metastatic spread. We report of a case of CCEOT in a 63 year old female patient which was first treated with enucleation; however recurrence prompted a segmental resection along with coronoid and condyle.

Management of synodontia between dilacerated permanent maxillary central incisor and supernumerary tooth with aid of cone-beam computed tomography.

A malformed tooth characterized by one or more developmental disturbances is often difficult to treat. When such teeth are present in anterior region, they pose a technical challenge for the clinician to restore esthetics as well as function. This case describes endodontic, surgical, and restorative management of fused and dilacerated maxillary central incisor. Cone-beam computed tomography (CBCT) was used in the present case to aid in understanding of complicated tooth morphology and managing the case successfully.

Frequency of second mesiobuccal canal in permanent maxillary first molars using the operating microscope and selective dentin removal: A clinical study.

PURPOSE: The aim of this study was to investigate whether the combination of operating microscope and selective dentin removal increased the frequency of second mesiobuccal (MB2) canal detection in permanent maxillary first molar teeth. MATERIALS AND METHODS: One hundred fifty permanent maxillary first molars indicated for root canal treatment were randomly selected from patients belonging to the age group of 18-45 years irrespective of gender. After access cavity preparation and location of main canals, the MB2 canal orifice was sought in all teeth with an endodontic explorer under direct vision (Stage I), then under magnification with the aid of operating microscope (Stage II) and finally with the combined use of operating microscope and selective dentin removal (Stage III). RESULTS: MB2 canals were detected in 36%, 54% and 72% of the teeth in Stages I-III, respectively. CONCLUSION: This study demonstrated that dental operating microscope when used along with adjunctive aids such as selective dentin removal/troughing and good clinical knowledge will increase the ability of dental clinician to locate MB2 canals.
