1. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

2. Influence of root dentin treatment on the push-out bond strength of fibre-reinforced posts
Abstract This study evaluates the influence of root dentin treatment with NaOCl alone and combined with EDTA, with and without ultrasound activation, on the push-out bond strength (BS) of fiber-reinforced posts in weakened roots, cemented with RelyX or Panavia. The root canals of 42 maxillary canines were instrumented with Reciproc and 2.5% NaOCl. In the cor

3. The effect of standardised implantoplasty protocol on titanium surface roughness: an in-vitro study
Abstract: To analyse the changes of surface characteristics of machined and moderately roughened titanium disks following a standardised implantoplasty protocol. Forty titanium discs (machined: n = 20; moderately roughened: n = 20) were instrumented with one half of each disc maintained as the control (non-instrumented). The standardised implantoplasty proto

4. Relined fiberglass post: an ex vivo study of the resin cement thickness and dentin-resin interface
Abstract The aim of this study was to evaluate the thickness of resin cements in the root thirds when using conventional fiberglass posts (CP) and relined fiberglass posts (RP) in weakened roots and to evaluate the morphological characteristics of the dentin-resin interface. Forty human maxillary anterior teeth had the crown sectioned below the cemento-ename

5. Effect of grinding and heat treatment on the mechanical behavior of zirconia ceramic
Abstract The present study investigated the effect of grinding on roughness, flexural strength, and reliability of a zirconia ceramic before and after heat treatment. Seven groups were tested (n = 15): a control group (labeled CG, untreated), and six groups of samples ground with diamond discs, simulating diamond burs, with grits of 200 µm (G80); 160 µm (G

6. Evaluation of condyle defects using different reconstruction protocols of cone-beam computed tomography
This study was conducted to investigate how well cone-beam computed tomography (CBCT) can detect simulated cavitary defects in condyles, and to test the influence of the reconstruction protocols. Defects were created with spherical diamond burs (numbers 1013, 1016, 3017) in superior and/or posterior surfaces of twenty condyles. The condyles were scanned, and

7. Avaliação da customização por desgaste de pinos pré-fabricados de fibra de vidro / Evaluation of fibre posts submitted to customization of the apical portion
The purpose of this study was to evaluate fibre posts (White Post DC/FGM) submitted to customization of the apical portion. Experiment 1: 5 #4 posts were divided into five groups (G) and submitted to different custom adaptation treatments: GA no surface treatment, GB- industrial shaping tool (Dentsply), GC- #3195 fine diamond bur (KG Sorensen), GD- medium-gr

8. Effect of relining on fiber post retention to root canal
One of the clinically relevant problems dentists face when restoring endodontically treated teeth is the mismatch between fiber post and post space diameters, which results in an excessively thick resin cement layer. Fiber post relining appears as a solution for this problem. OBJECTIVES: The aim of this study was to evaluate the effect of fiber post relining

9. A influência da técnica do preparo cavitário utilizando laser Er: YAG e dos tipos de materiais restauradores na prevenção de cárie secundária
The influence of the cavity preparation technique and the types of restorative materials containing fluorides in the prevention of the secondary caries lesions was evaluated in this in vitro study. In a logic sequence the subject was approach by four manuscripts. The first study made a bibliographic revision about the laser employment in the prevention of th

10. Histological evaluation of the human pulp response to different cavity instrumentation and restorative techniques / Avaliação histológica da resposta pulpar humana a diferentes técnicas de instrumentação cavitária e de restauração
Este estudo se propõe a analisar a resposta pulpar de dentes humanos a preparos cavitários de classe V, em função de duas diferentes técnicas de instrumentação e de duas diferentes técnicas de restauração. Para tal, cavidades classe V, nas superfícies vestibulares de 48 pré-molares hígidos de pacientes entre 11 e 25 anos, que estavam em tratamen

11. Evaluation of the risk of a stripping perforation with gates-glidden drills: serial versus crown-down sequences
The aim of this study was to evaluate the remaining dentine/cementum thickness using Gates-Glidden burs in serial and crown-down sequences and to observe which of the two sequences is the safest for preparing mesial roots of molars. Thirty-six left and right human mandibular first molars were selected. Standard access cavities were made and initially explore

12. Bond strength of resin modified glass ionomer cement to primary dentin after cutting with different bur types and dentin conditioning
The aim of this in vitro study was to evaluate the effect of different bur types and acid etching protocols on the shear bond strength (SBS) of a resin modified glass ionomer cement (RM-GIC) to primary dentin. Forty-eight clinically sound human primary molars were selected and randomly assigned to four groups (n=12). In G1, the lingual surface of the teeth w
