1. O que fazer quando os incisivos inferiores permanentes erupcionam por lingual dos decíduos?
A decisão está entre extrair os dentes decíduos que não esfoliaram ou aguardar até que esfoliem, sem a necessidade de uma intervenção mais traumática à criança, que, na maioria das vezes, nunca se submeteu a um procedimento cirúrgico. Esta segunda opção costuma não ser bem aceita por alguns pais, que vêm em busca de uma solução imediata p

5. Evaluation of pain perception during orthodontic debonding of metallic brackets with four different techniques
Abstract Objective The aim of this study was to evaluate patients’ pain levels during four different debonding procedures. The null hypothesis was that the pain perception of the patients undergoing four different debonding applications was not statistically significant different. Material and Methods One hundred and twenty orthodontic patients who under

6. Rat dental pulp stem cells: isolation and phenotypic characterization method aiming bone tissue bioengineering
ABSTRACT: Dental pulp stem cells (DPSC) have been showing a considerable potential for regenerative medicine. Pulps were collected from lower incisors (n=2) through direct access of the tooth pulp chamber. The isolated cells were cultured in alfa-MEM 10% FBS, in standard culture conditions. At the third passage, DPSC were characterized by flow cytometry (MHC

7. Age-related changes in the Brazilian woman’s smile
Abstract The aim of this research was to evaluate age-related changes in the smile of Brazilian women. The sample consisted of 249 Brazilian women who had not undergone previous orthodontic treatment or facial surgery. They were divided into four groups, according to age: G1 (20-29), G2 (30-39), G3 (40-49) and G4 (50 or older). Standardized front view photog

8. Breastfeeding, bottle feeding and risk of malocclusion in mixed and permanent dentitions: a systematic review
Abstract The aim of the present study was to search for scientific evidence concerning the association between breastfeeding and bottle feeding and risk of malocclusion in mixed and permanent dentitions. An electronic search was performed in eight databases up to February 2015. Additionally, a gray literature search and hand searches of the reference lists o

9. Volume of sealer in the apical region of teeth filled by different techniques: a micro-CT analysis
Abstract The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments. Teeth were randomly distributed into four groups according to root canal sealers (AH Plus, Endofill, Sealapex, and Sealer 26) and

10. Micro-CT evaluation of the radioprotective effect of resveratrol on the mandibular incisors of irradiated rats
Abstract The purpose of this study was to perform a microcomputed tomographic evaluation of the radioprotective effect of resveratrol on the volume of mandibular incisors of irradiated rats. A second aim was to make a quantitative assessment of the effect of x-ray exposure on these dental tissues. Twenty adult male rats were divided into four groups: control

11. In vitro re-hardening of artificial enamel caries lesions using enamel matrix proteins or self-assembling peptides
ABSTRACT Objectives To assess the re-hardening potential of enamel matrix derivatives (EMD) and self-assembling peptides in vitro, hypothesizing that these materials may increase the mineralization of artificial carious lesions and improve hardness profiles. Material and Methods Forty-eight enamel samples were prepared from extracted bovine lower central

12. Influence of implant-abutment angulations and crown material on stress distribution on central incisor: a 3D FEA
Abstract Aim: To investigate the effect of implant-abutment angulation and crown material on stress distribution of central incisors. Finite element method was used to simulate the clinical situation of a maxillary right central incisor restored by two different implant-abutment angulations, 15° and 25°, using two different crown materials (IPS E-Max CAD
