1. Influence of crosshead speed on failure load and failure mode of restored maxillary premolars
We analyzed the effect of the crosshead speed of an applied load on failure load and failure mode of restored human premolars. Fifty intact, noncarious human premolars were selected. Class II mesio-occlusodistal preparations were made with a water-cooled high-speed preparation machine, and the teeth were restored with composite resin. The specimens were divi

2. Cost analysis of materials used in Class III, IV and V composite resin restorations
AIM: To assess the total cost of direct and indirect materials used in Class III, IV and V composite resin direct restorations. METHODS: The calculation of costs was based on the method of variable costing system. A list of the materials was obtained by a panel of experts and based on the excellence standards established in the literature for dental team tre

3. Marginal microleakage of class V resin-based composite restorations bonded with six one-step self-etch systems
This study compared the microleakage of class V restorations bonded with various one-step self-etching adhesives. Seventy class V resin-based composite restorations were prepared on the buccal and lingual surfaces of 35 premolars, by using: Clearfil S 3 Bond, G-Bond, iBond, One Coat 7.0, OptiBond All-In-One, or Xeno IV. The Adper Single Bond etch-and-rinse

4. Marginal adaptation of class V composite restorations submitted to thermal and mechanical cycling
Objective This study evaluated the effect of the margin location and an adhesive system on the marginal adaptation of composite restorations. Material and Methods Class V cavities were prepared in bovine teeth with the gingival margin on the dentin and the incisal margin on the enamel. The cavities were restored with a micro-hybrid composite resin using an

5. Characterization of aqueous silver nitrate solutions for leakage tests
OBJECTIVE: To determine the pH over a period of 168 h and the ionic silver content in various concentrations and post-preparation times of aqueous silver nitrate solutions. Also, the possible effects of these factors on microleakage test in adhesive/resin restorations in primary and permanent teeth were evaluated. MATERIAL AND METHODS: A digital pHmeter was

6. Analysis of the marginal sealing of restorations after cavity preparation performed with laser Er,Cr:YSGG using different parameters in dentin / Análise do selamento marginal de restaurações realizadas após preparo cavitário com laser de Er;Cr:YSGG utilizando diferentes parâmetros em dentina hígida
The aim of this work was to evaluate dye penetration of Class V restorations in cavity preparations obtained with different power setting of an Er;Cr:YSGG laser or with diamond bur and high-speed handpiece. Sixty samples of dentin were divided into six groups (n=10). The first group served as a control with standardized diamond bur cut (G1); the other groups

10. Influence of human and bovine substrate on the microleakage of two adhesive systems
The aim of this study was to evaluate in vitro the marginal sealing of two adhesive systems and to analyze the influence of human and bovine substrates on marginal microleakage in enamel. Rectangular-shaped class V cavities (4 mm wide x 2 mm high x 2 mm deep) were made as follows: 8 cavities were prepared on the buccal and lingual surfaces of the human teeth

11. Análise in vitro do efeito inibitório de restaurações contendo o monômero antibacteriano MDPB na progressão de cáries secundárias em raizes dentárias / in vitro analysis of inhibitory effects of the antibacterial monomer MDPBcontaining restorations on the formation of secondary root caries
This in vitro study aimed to analyze the potential of restorative materials containing the antibacterial monomer 12-methacryloyloxydodecylpyridinium bromide (MDPB) for controlling the advance of bacterial induced secondary root caries-like lesions. Class V cavities (2 mm x2 mm) were prepared in seventy-five human root fragments. Specimens were randomly divid

12. Influence of thermal stress on marginal integrity of restorative materials
The aim of this study was to evaluate the influence of thermal stress on the marginal integrity of restorative materials with different adhesive and thermal properties. Three hundred and sixty Class V cavities were prepared in buccal and lingual surfaces of 180 bovine incisors. Cervical and incisal walls were located in dentin and enamel, respectively. Speci
