BACKGROUND This study compared the shear bond strength of metallic brackets bonded with Single Bond and Assure bonding agents under dry and saliva-contamination conditions. METHODS Sixty sound premolar teeth were selected, and stainless-steel brackets were bonded on enamel surfaces with Single Bond and Assure bonding agents under dry condition or with saliva contamination. Shear bond strength...

statement of problem: following the increasing use of composites in restoring anterior and posterior teeth, problems due to its technique sensitivity have become a major concern. one of these problems is the possibility of contamination of dentin with saliva, blood and/or gingival fluid in different stages of bonding procedure, even with application of different methods of isolation. however, b...

Saliva, as a medium for assessing adrenocortical function in humans, has many advantages and a few distinct disadvantages. Interpretation of measurements of saliva cortisol is complicated by the contamination of saliva by steroid-binding proteins from blood plasma, enzyme activity in the salivary gland that converts cortisol to cortisone, and the amplification in saliva of the episodic fluctuat...

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-conta...

Salivary oxidative stress markers represent a promising tool for monitoring of oral diseases. Saliva can often be contaminated by blood, especially in patients with periodontitis. The aim of our study was to examine the impact of blood contamination on the measurement of salivary oxidative stress markers. Saliva samples were collected from 10 healthy volunteers and were artificially contaminate...

OBJECTIVES The purpose of this in vitro study was to evaluate the effect of artificial saliva contamination on microtensile bond strength to pulp chamber dentin. METHODS Clearfil SE Bond (SEB) (Kuraray, JAPAN) adhesive system and Clearfil Photo Posterior (CPP) (Kuraray, JAPAN) composite resin were used. Twenty extracted caries-free human molar teeth were randomly distributed into four groups....

During the spread of pandemic disease, dental practice come across highest risk corona virus infection by exposure from patient saliva, aerosols generation during procedure, blood contamination oral surgical procedure. This can be transmitted symptomatic to asymptomatic individual through aerosol spread, saliva contamination. Due its ability airborne transmission, so generated natural activity ...

PURPOSE The aim of this study was to assess the effect of water and saliva contamination on the shear bond strength and failure site of orthodontic brackets and lingual buttons. MATERIALS AND METHODS 120 bovine permanent mandibular incisors were randomly divided into 6 groups of 20 specimens each. Both orthodontic brackets and disinclusion buttons were tested under three different enamel surf...

objective: this study evaluated the effect of saliva contamination during bonding procedures without removing saliva on shear dentin bond strength of three adhesive generations when rubber dam isolation is not feasible. materials and methods: flat superficial dentin surfaces of seventy-two extracted human molars were randomly divided into three groups (a: scotch bond mp plus (sbmp), b: single b...

A clinical study was designed to determine if there was a predictable relationship between saliva and plasma codeine concentrations. Drug-free volunteers (n = 17) were administered a 30-mg dose of liquid codeine phosphate. Plasma and saliva specimens were collected at various times for 24 h after administration. Plasma and saliva were analyzed for codeine and morphine by positive-ion chemical i...
