1. Dentin pretreatment and adhesive temperature as affecting factors on bond strength of a universal adhesive system
Abstract Objectives: To evaluate the effects of dentin pretreatment and temperature on the bond strength of a universal adhesive system to dentin. Material and Methods: Ninety-six extracted non-carious human third molars were randomly divided into 12 groups (n=8) according to Scotchbond Universal Adhesive (SbU) applied in self-etch (SE) and etch-and-rinse

2. Análise morfológica e da resistência adesiva dos tecidos dentais duros irradiados com lasers de pulsos ultracurtos / Evaluation of dental hard tissues irradiated with ultra-short pulsed lasers. Influence on surface morphology and microtensile bond strength
The development of restorative dentistry has reached the era of esthetic adhesive restorations and minimally invasive approach, for which innovative techniques and advanced materials are constantly introduced. Conservative techniques aim not only to remove carious dental substrate, but also to prepare cavity surfaces for adhesive restoration. The main object

3. Influence of sterilization method on the bond strength of caries-affected dentin
This study evaluated the effect of sterilization method on the bond strength of caries-affected dentin before artificial caries development and after restoration. Twelve bovine incisors were sectioned perpendicularly to their long axes at 7 mm from the amelodentinal junction. They were painted with acid-resistant nail varnish, except on an exposed coronal de

4. Papain-based gel for biochemical caries removal: influence on microtensile bond strength to dentin
This study investigated the influence of a papain-based gel (Papacárie) for chemo-mechanical caries removal on bond strength to dentin. Human molars were assigned to the following groups: Group 1: sound teeth were flattened to expose dentin; Group 2: after flattening of surfaces, the papain-based gel was applied on the sound dentin; Group 3: overlying ename

5. Effect of additional acid etching on bond strength and Weibull modulus of adhesive systems applied on sound and affected dentin / Efeito do condicionamento ácido adicional na resistência de união e Módulo de Weibull de sitemas adesivos aplicados em dentina sadia e afetada por cárie
O objetivo deste estudo foi avaliar o efeito do condicionamento adicional com ácido fosfórico à 35% na resistência de união e módulo de Weibull de dois sistemas adesivos aplicados em dentina sadia e afetada por cárie. Noventa molares humanos com lesão cariosa oclusal foram desgastados produzindo superfícies oclusais planas, com DAC circundada por DS

6. Efeito do digluconato de clorexidina na estabilidade da união de sistemas adesivos e dentina sadia ou afetada por carie / Effect of clorhexidine digluconate on the bond strength of etch-and-rinse adhesives to normal/caries-affected dentin
The aim of this study was to evaluate the effect of 2% chlorhexidine digluconate on the bond strength of etch-and-rinse adhesives applied to sound (SD) and caries-affected dentin (CAD). It is hypothesized that CHX does not have a detrimental effect on the bond strength to sound and caries-affected dentin, as well as that CHX may decelerate the mechanical deg

7. Comportamento dos sistemas adesivos com fluor frente ao desafio cariogenico
The aim of this study was to investigate the behavior of fluoride-free and fluoride-containing adhesive systems subject to dynamic chemical induction of secondary caries, by means of the microtensile bond strength test, establishment of carious lesion depth and the amount of fluoride-ion release from each adhesive system. Eighty extracted bovine incisors wer

8. "Influência do método de remoção de cárie na resistência adesiva de um sistema autocondicionante" / Microtensile bond strength of self-etching adhesives to caries-affected dentine
New methods for carious dentine removal have been proposed, such as, lasers and chemo-mechanical. This in vitro study aimed to evaluate the influence of caries removal methods (steel burs, Er, Cr: YSGG laser and Carisolv) on microtensile bond strength of self-etching adhesive systems. 50 extracted carious human molars were ground to expose flat surfaces wher
