Moisture contamination of etched enamel during application of sealant is the most frequently cited reason for sealant failure. In preliminary studies, a dentin bonding agent (Scotchbond Dual Cure, 3M, St. Paul, MN) has been shown to bond adequately to etched enamel after salivary contamination. This study investigated bond strength in vitro, when a bonding agent was used beneath sealants under ...

objectives: osteoblasts are the most important cells in the osseointegration process. despite years of study on dental implants, limited studies have discussed the effect of saliva on the adhesion process of osteoblasts to implant surfaces. the aim of this in vitro study was to evaluate the effect of saliva on morphology and differentiation of osteoblasts attached to implant surfaces. materials...

One source of error in gastric secretion studies is swallowed saliva. The possibility that salivary thiocyanate might be used to measure this contamination has been investigated. Thiocyanate concentration was measured in saliva and gastric juice collected simultaneously in 22 duodenal ulcer patients undergoing routine insulin and histamine secretion studies. On stimulation, despite the increase...

Saliva contamination of etched enamel before sealant application is the most common reason for failure fissure sealants, thus affecting effect caries prevention. This study aimed to evaluate shear bond strength (SBS) and microleakage resin-based on saliva-contaminated after rinsing, re-etching, applying universal adhesive. Fifty human third molars were sectioned into 2 parts embedded in acrylic...

OBJECTIVES This study aimed to evaluate the effects of saliva contamination on the metallic bracket microleakage bonded with two moisture-tolerant bonding systems. MATERIALS AND METHODS Ninety freshly extracted premolar teeth were randomly divided into six groups of 15 with the following treatments: G1 (control): After acid etching, Assure primer and Assure adhesive were applied to non-contam...

This study determined the effect of cleansing solutions on microtensile bond strengths of self-etch adhesives to saliva-contaminated dentin. Seventy five human molars were ground flat to expose mid-depth dentin, and randomly assigned to 5 groups (n=15): no contamination, saliva contamination without cleansing, saliva and cleansing with water, saliva and cleansing with 2% chlorhexidine, and sali...

Background and Aim: One of the important factors in microleakage of fissure sealants is saliva contamination. Researchers believe that applying bonding agents can reduce the microleakage. The present study compared the microleakage of a fissure sealant contaminated with artificial saliva at different curing times with or without using a bonding agent. Materials and Methods: In this in-vitro ...

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...
