AIM To evaluate the bonding temperature effect on dentin-restoration microleakage. The null hypothesis of the study is that the score of microleakage is identical among different adhesive bondings at different temperatures. MATERIALS AND METHODS Ninety caries free maxillary premolars were selected. Class V cavities were prepared on the cemento enamel junction (CEJ) of the buccal sides with en...

The crystal structure of Ci2HiiN2SiCl3 (monoclinic, P2i/m, Z = 2, with a: 9.284(4), b: 7.226(2), c: 10.832(5) Ä, ß = 115.14(3)°) was refined to R(F) 0.035 from 1228 independent reflections. A trigonal bipyramidal, pentacoordinate silicon is observed. The chelated complex shows two different Si-N bonds, a coordinative bond (1.984(2) A) between Si and N on the axial position and a Si-N single bon...

AIM The aim of this ex vivo study was to compare the antibacterial activity of total-etch and self-etch adhesive systems against Streptococcus mutans, Lactobacillus acidophilus, and Actinomyces viscosus through disk diffusion method. MATERIALS AND METHODS The antibacterial effects of Single Bond (SB) and Adper Prompt (AP) and aqueous solution of chlorhexidine 0.2% (positive control) were test...

BACKGROUND To investigate pulp response to the application of two types adhesive systems (total-etch and self-etch) in human premolar teeth. MATERIALS AND METHODS Cavities limited to enamel walls in all margins with 2.5 mm depth were prepared on buccal surfaces of thirty three human premolars. The cavities were treated with the following adhesive. Single Bond (SB) and Prompt L-Pop (PLP). The ...

statement of problem: adhesion to root canal dentin is one of the necessary characteristics of endodontic sealers. mta fillapex (angelus, londria, pr, brazil) is one of the recently introduced mta-based sealer. only a limited number of studies have evaluated the bonding of this sealer to the dentin, with conflicting results. objectives: the purpose of this study was to evaluate the bond strengt...

Objectives: The present study was carried out to compare the shear bond strength of metallic brackets bonded with single Bond and Assure bonding agents under dry and saliva contamination conditions. Materials and Methods: A total 60 sound premolar teeth were selected for the purpose of this in vitro study and stainless steel brackets were bonded on enamel surfaces with single bond and assure bo...

BACKGROUND The purpose of this study was to compare the shear bond strength of nanocomposite resin to superficial dentin and deep dentin using two different dentin bonding systems. MATERIALS AND METHODS All teeth were sectioned at various levels (superficial dentin: Dentin within 0.5-1 mm of dentinoenamel junction; deep dentin: Dentin within 0.5 mm of the highest pulp horn) using a Carborundu...

Background and aims. Bonding of composite resin filling materials to pulp protecting agents produces an adhesive joint which is important for the quality of filling as well as success of restoration. We aimed to assess the bond strength of composite resin to three pulp capping biomaterials: Pro Root mineral trioxide aggregate (PMTA), Root MTA (RMTA) and calcium enriched mixture (CEM) cement, us...
