the efficacy of correctly applied fissure sealants has been revealed in the prevention of caries. saliva and moisture contamination of the etched enamel surface before sealant placement can decrease the bonding strength of the sealant to the enamel. the aim of this study was to test the new bonding agents containing nano-fillers in order to reduce the negative effect of saliva contamination on ...

OBJECTIVE To evaluate the influence of saliva contamination on the bond strength of metallic brackets bonded to enamel with hydrophilic resin composite. METHODS Eighty premolars were randomly divided into 4 groups (n = 20) according to bonding material and contamination: G1) bonded with Transbond XT with no saliva contamination, G2) bonded with Transbond XT with saliva contamination, G3) bond...

Excessive salivary contamination of induced sputum samples prevents the satisfactory examination of lower airway inflammation. The effects of salivary contamination on different sputum fluid phase measures and the levels of salivary contamination preventing analysis are not defined. The present study sought to examine this by investigating the effect of increasing salivary contamination on indu...

PURPOSE The purpose of this study was to evaluate the microleakage and penetration ability of sealing materials applied under different conditions of contamination. METHODS One hundred twenty extracted human molar teeth were randomly assigned to 12 groups. The treatment groups were defined by the combination of sealing materials (Concise; Optibond system; Optibond system plus Concise) and 4 s...

BACKGROUND Diagnostic value of whole saliva may be compromised when blood contamination is present in saliva samples. Measuring transferrin level in saliva samples has been used for detecting the level of blood contamination in saliva. The aim of this study was to investigate the validity of transferrin as a proper biomarker for blood contamination in whole saliva. METHODS Thirty younger (mea...

PURPOSE Glass ionomer sealants (GISs) are promoted in pediatric dentistry for their moisture-friendly properties. This study's purpose was to investigate the marginal leakage of a glass ionomer sealant (Fuji Triage) under different moisture environments. METHODS Eighty extracted teeth were distributed into 4 groups: (1) control; (2) saliva contamination with 1-second air-thinning; (3) saliva ...
