Dental adhesives come into direct contact with oral tissues. Due to this close and long-term contact, the materials should exhibit a high degree of biocompatibility. The aim of this study was to evaluate the genotoxic effect of dental adhesives on human lymphocytes in vitro. Polymerized dental adhesives (Excite, Adper Single Bond 2, Prompt L-pop and OptiBond Solo Plus) were eluted in dimethyl s...

OBJECTIVE The objective of this study was to evaluate the effect of operator variability on microleakage with different adhesive systems. MATERIALS AND METHODS A total of 180 standardized Class V cavities were prepared on facial and lingual of 90 extracted human premolar teeth and randomly assigned to five groups according to the adhesive systems used (n = 36): Prime and Bond NT (PB), Single ...

This study aimed to assess in vitro cytotoxicity for Adper™ Scotchbond™ 1 XT (SB1), Clearfil™ SE Bond 2 (CSE) and Universal (SBU), using MDPC-23 cell cultures. The metabolic activity, protein content, death types cellular morphology were evaluated. All extracts determined a significant reduction metabolism viability. CSE significantly reduced cell’s activity at its higher concentrations (50% 10...

This study used functional magnetic resonance imaging (fMRI) to investigate the neural mechanisms underlying two types of spatial transformations: imagined object rotations and imagined rotations of the self about an object. Participants viewed depictions of single three-dimensional Shepard--Metzler objects situated within a sphere. A T-shaped prompt appeared outside of the sphere at different ...

Recent research suggests that infants and toddlers succeed at a wide range of non-elicited-response false-belief tasks (i.e., tasks that do not require children to answer a direct question about a mistaken agent's likely behaviour). However, one exception to this generalization comes from verbal anticipatory-looking tasks, which have produced inconsistent findings with toddlers. One possible ex...

UNLABELLED During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. OBJECTIVE this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) and apical (A) thirds of th...

Background and Aim: Preparation of tooth structure by laser systems produces a surface with different characteristics. Therefore, selecting an appropriate bonding system is necessary to achieve the maximum bond strength. The aim of this study was to compare the bond strength of Adper Single Bond 2 adhesive and Single Bond Univer-sal to dentin prepared by bur or laser. Materials and Methods: ...
