Abstract This in vitro study was performed to compare the microtensile bond strengths (MTBS) of current self‐etching adhesives dentin and evaluate effects artificial aging [(thermocycling (TC) and/or mechanic loading (ML)] on MTBS nanoleakage adhesives. Two‐step (AdheSE Bond, Clearfil Protect SE Optibond Self‐Etch) one‐step (Hybrid G‐bond, Tri‐S Adper Prompt L‐Pop) were tested. Resin composite build‐ups created, specimens subjected 10 4 TC, 5 ML, /10 TC/ML. Non‐aged served as controls. In...

summary This study investigated the shear bond strengths of sectioned human mandibular incisor edge fragments reattached using luting cements, bonding agents or restored with composite resins. Seventy teeth were randomly distributed among six experimental groups and a control group. Leaving half anatomic crowns exposed, embedded in self‐cure acrylic resins exposed part then sectioned. The 1–4 bonded to their respective Clearfil Liner Bond 2V, Scotch Multi Purpose Plus, Panavia‐F 3M Opal...

To evaluate the cytotoxic effects of five different light-cured orthodontic bonding composites.The composites Heliosit Orthodontic (Ivoclar), Transbond XT (3M Unitek), Bisco ORTHO (Bisco), Light Bond (Reliance), and Quick Cure (Reliance) were prepared, samples extracted in 3 mL BME (Basal Medium Eagle) with 10% newborn calf serum for 24 hours. The L929 cells plated (25,000 cells/mL) a 96-well dish maintained humidified incubator hours at 37 degrees C, 5% CO(2), 95% air. After incubation...

The purpose of this study was to evaluate the influence a xylitol lozenge on dental plaque pH profile fixed orthodontic patients. Twelve volunteers participated in study. Before measurement pH, subjects were asked refrain from brushing their teeth for 48 hours and eating drinking two hours. subjects' baseline recorded using touch technique. It followed by one-minute rinse with 15 ml 10% solution sucrose, subsequent measurements carried out during next one hour. Xylitol lozenges taken five...

The purpose of this study was to determine whether the application two antibacterial mouth rinses etched and unetched enamel affects shear bond strength (SBS) an orthodontic composite resin. Eighty-five lower human incisors were divided into five groups, ie, group 1: control group, no rinse used; groups 2 3: applied intact surface before etching; 4 5: enamel. A bonding agent a resin teeth surface. For testing, specimens mounted in universal testing machine, apparatus attached compression...

As bond strength of currently available adhesive systems in caries-affected teeth dentin on primary tooth was not well known, the two bonding (PQI and OptiBond Solo Plus) evaluated sound molar observed micromorphology adhesive-dentin interfaces.By grinding both (n = 30) approximal surfaces teeth, flat were obtained. The prepared bonded with one each a composite resin. After storing specimens water at 37 degrees C for 24 h, samples sectioned tested by microshear test method. data...

Summary Five current dentin adhesives were evaluated for their ability to bond caries‐affected dentin. The materials were: total etch [Solid Bond (SB)], two self‐etch [Clearfil SE (CSE), Etch and Prime (EP)], one bottle [Prime 2·1 (PB), One Coat (OCB)]. Sixty extracted molar teeth with proximal caries (mesial or distal) extending into mid‐dentin used. By grinding normal surfaces, flat surfaces obtained. then bonded each adhesive system composite resins added the by packing material a...

summary This study was aimed at investigating the internal adaptation of a ceramic (Ceramco II) and two composite resin inlay materials (SureFil 3M Filtek Z 250 TM ) using silicon replica technique as an indicator. Forty‐five standard mesial–occlusal–distal (MOD) cavities were prepared into brass moulds by computer numerically controlled system. Inlays according to manufacturers’ instructions with indirect methods. Replicas inlays produced polyvinyl siloxane material (Elite H‐D). The spaces...

The aim of the present study was to determine whether application different primers containing antibacterial agents (Micro Prime™, Seal&Protect™, and Gluma Desensitizer™) can affect shear bond strength (SBS) an orthodontic resin composite.

The aim of this study was to determine the effect three storage solutions and two durations on microshear bond strength (microSBS) a resin composite. Sixty non-carious human permanent molars were stored in (0.1% thymol, 10% formalin, distilled water). Each tooth separated mesio-distally into parts. Specimens first part for 24 hours, while specimens second months solutions. After each period, enamel surface covered with composite combination an etch-rinse adhesive system. then serially...

To determine the cytotoxicity of three commercial mouthrinses Klorhex, Andorex and Tanflex on buccal epithelial cells using micronucleus (MN) test.

The aim of this study was to test the hypothesis that bonding ability antibacterial system primary dentin not different from parental material which did contain any component.Extracted human non-carious molars were ground expose coronal dentin, and then randomly divided into two experimental groups: treatment with Clearfil Protect Bond or SE (Kuraray Medical Inc.). Composite-dentin sticks a cross-sectional area approximately 0.90 mm(2) prepared subsequently subjected microtensile bond...

To evaluate the cytotoxic effects of three different resin-modified orthodontic band adhesives.Three adhesives (Bisco Ortho Band Paste LC, Multi-Cure Glass Ionomer Cement, and Transbond Plus Light Cure Adhesive) were prepared samples extracted in 3 mL Basal Medium Eagle with 10% newborn calf serum for 24 hours.
