Double Gemination or Fusion of a Permanent Mandibular Second Molar: A Case Report.

Gemination and fusion are developmental conditions affecting the shape of teeth in both primary and permanent dentition. A 12-year-old girl presented for clinical assessment and the examination revealed an unusually shaped mandibular right second molar with irreversible pulpitis. Correlation of the intraoral and radiological appearance of this tooth suggested a diagnosis of either double gemination or fusion.

Root and canal configurations of mandibular first molars in a South African subpopulation.

Purpose: This study investigated root number and canal configurations, including morphological variations, of mandibular first molars in a subpopulation of South Africans.

Methods: Two calibrated examiners retrospectively evaluated 371 mandibular first molars by using high-resolution cone-beam CT images and the Vertucci classification system with the additions of Sert and Bayirli. Internal and external configurations were recorded, and correlations of sex and age with root number and canal configuration were determined with the chi-square and Fisher exact tests (P < 0.

Self-reported knowledge, attitudes, and practice of final-year dental students in relation to child abuse: A multi-centre study.

Background: The number of child abuse cases is increasing worldwide; therefore, it is important to educate individuals having contact with children about it. This includes dentists who play a pivotal role in detecting and reporting child abuse.

Aim: To identify and compare the final- year dental student's knowledge, attitudes, and practice in relation to child abuse.

Endodontic treatment of dentin dysplasia type I D.

Dentin dysplasia (DD) Type I is a developmental condition affecting dentin, inherited in an autosomal-dominant pattern or occurring due to a new mutation. Whilst the crowns of DD Type I affected teeth appear clinically normal, the roots are blunt and shortened. Pulp necrosis and periapical pathoses may be seen in the absence of obvious causes.

Root and canal configurations of maxillary premolars in a South African subpopulation using cone beam computed tomography and two classification systems.

This cone beam computed tomography (CBCT) study aimed to describe the maxillary premolar anatomy of a South African subpopulation using two classification systems. A total of 601 premolars were evaluated. For each tooth, the root number and canal configurations were described using the classification systems devised by Vertucci (1984) and Ahmed et al.

Allergic contact dermatitis from resin-modified glass ionomers.

Monomers in a variety of dental materials may cause allergic contact dermatitis. While resin materials have been implicated in the onset of this condition, there is a paucity of evidence linking the condition to the resin-modified glass ionomers (RMGIs). This report documents a rare case of a dentist who developed allergic contact dermatitis following exposure to a RMGI.
