1. Printing 3D models of canine jaw fractures for teaching undergraduate veterinary medicine
Abstract Purpose To develop 3D anatomical models, and corresponding radiographs, of canine jaw fractures. Methods A base model was generated from a mandibular bone scan. With this model it was possible to perform fracture planning according to the anatomical location. Results The 3D base model of the canine mandible was similar in conformation to the n

3. Pre-eruptive intracoronal resorption on cone beam computed tomography: two case reports
RESUMO A reabsorção intra-coronária pré-eruptiva (RIP) é uma alteração rara que ocorre na coroa de dentes não erupcionados. O objetivo desse trabalho é documentar dois casos raros de RIP em caninos inclusos nas imagens de tomografia computadorizada de feixe cônico (TCFC). As imagens de TCFC de alta resolução (Prexion 3D) foram solicitadas cuja in

5. Restorative Possibilities Using Zirconia Ceramics for Single Crowns
Resumo Dois casos clínicos são apresentados para explorar as diferenças técnicas e discutir as vantagens e desvantagens de se utilizar zircônia com cerâmica estratificada ou monolítica para confeccionar coroas unitárias. O primeiro caso descreve os passos clínicos na confecção de uma coroa monolítica no segundo pré-molar esquerdo utilizando uma

6. Hyperplastic dental follicle: case report
RESUMO O folículo pericoronário caracteriza-se como uma área radiolúcida em volta de um dente incluso. Acredita-se que esses folículos podem originar cistos e tumores. O objetivo deste trabalho foi relatar o caso clínico de um paciente do gênero feminino, 15 anos de idade, normossistêmica, que apresentava folículo pericoronário aumentado, envolvend

7. Time expended on managing molar incisor hypomineralization in a pediatric dental clinic in Nigeria
Abstract This study assessed the difference in the number of visits made to a dental care clinic and the time spent providing specific dental treatment for children with and without molar incisor hypomineralization (MIH). Children aged 8 to 16 years who presented at the Pediatric Dental Unit of the Obafemi Awolowo University Teaching Hospital Complex, in Ile

8. Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatment with triple antibiotic paste (TAP) or calcium hydroxide (

10. Case-control study on factors associated with crown fractures in the primary dentition
The purpose of the present study was to identify the factors associated with dental trauma in preschool children. This case-control study was nested in a population-based cross-sectional study involving a random sample of 301 children one to five years of age in the city of Diamantina, Brazil. The case group was made up of children with at least one fracture

11. Filling of simulated lateral canals with gutta-percha or thermoplastic polymer by warm vertical compaction
The aim of this study was to evaluate the ability of gutta-percha and a thermoplastic synthetic polymer (Resilon) to fill simulated lateral canals, using warm vertical compaction. Forty-five single-rooted human teeth were prepared using the rotary crown-down technique. Artificial lateral canals were made at 2, 5, and 8 mm from the working length (WL) in each

12. Spectrophotometric analysis of crown discoloration induced by MTA- and ZnOE-based sealers
Crown discoloration can be induced by root canal sealer remnants following root canal treatment. Objective: The aim of this study was to evaluate chromatic alterations in human tooth crowns induced by a Mineral Trioxide Aggregate-based sealer (MTA Fillapex®) and a commonly used ZnOE-based sealer (Roth-811). The tested null hypothesis was that the applicati
