An Uncommon Occurrence of Three-Fourth Molars Concomitant to Hypodontia in a Nonsyndromic Patient.

Bilaterally mandibular and maxillary fourth molars, concomitant to hypodontia, are uncommon. These dental anomalies, called hypohyperdontia, are rare and etiology is not well defined. Several complications may occur as a consequence of supernumerary teeth, such as teeth impaction, resorption of adjacent teeth, and development of cysts and tumors.

Hyperplastic dental follicle: a case report and literature review.

Hyperplastic dental follicle is an odontogenic hamartomatous lesion associated with delayed or tooth eruption failure in young patients. The occurrence of this pericoronal dental lesion may be single or multiple and it seems to be more frequent than literature has reported. We present a literature review focusing on the etiopathogenesis and clinicopathological features of this hamartomatous lesion in young patients.

Comparison of radiographic measurements obtained with conventional and indirect digital imaging during endodontic treatment.

The aims of this study were to evaluate the quality of indirect digitized radiographic images taken during endodontic procedures and to compare the measurements recorded with this technique to those obtained from conventional radiographs. Two-hundred conventional periapical radiographs taken at the undergraduate Endodontics Clinic of the Dental School of Bauru were digitized. The conventional and indirect digitized images were compared by three examiners as to the quality and accuracy of the measurements recorded during endodontic treatment, in canal length determination, gutta-percha adaptation, lateral condensation and final obturation.
