Measurement of increased latenight salivary cortisol (LNSC) is now a mainstay in the diagnosis of endogenous Cushing syndrome (1 ). Patients typically sample their saliva at home and are carefully instructed to avoid using potential contaminants, such as topical creams or ointments containing hydrocortisone (authentic cortisol). Using these creams or ointments can cause preanalytical contaminat...

Assay of hormones in saliva would be more convenient than assay in blood, but there is no information on the route by which hormones enter saliva, information that would provide insight into the clinical value of such assays. We have examined the mode of entry of various hormones into saliva. The results suggest that unconjugated steroids enter saliva by diffusing through the cells of the saliv...

AbstractIn the routine clinical situation, contamination by blood and/or saliva in restorative procedures can be happen non-cooperation of patient dental office. The aim study was to assess vitro shear bond strength a resin sealant associated with two types adhesives contaminated and blood. Healthy human molars were used specimens crowns sectioned bucco-lingual direction, thus obtaining segment...

AIM The aim of the study was to evaluate the effect of saliva contamination and compare the microleakage of three different pit-and-fissure sealants namely, Helioseal F, Enamel Loc and Fuji VII. MATERIALS AND METHODS Sixty recently extracted sound third molars were randomly assigned to three groups for three different sealant materials (n=20). Each sealant group was then randomly divided into...

INTRODUCTION Sealing ability is an important factor for a root-end filling material in endodontic surgeries. This in vitro study aimed to compare the sealing ability of mineral trioxide aggregate (MTA) and a new endodontic cement named calcium enriched mixture (CEM) cement as root-end filling materials. MATERIALS AND METHODS The experiments were carried out in dry, saliva or blood contaminate...

OBJECTIVE To evaluate the influence of saliva contamination on shear bond strength and the bond failure pattern of 3 adhesive systems (Transbond XT, AdheSE and Xeno III) on orthodontic metallic brackets bonded to human enamel. MATERIAL AND METHODS Seventy-two permanent human molars were cut longitudinally in a mesiodistal direction, producing seventy-two specimens randomly divided into six gr...

AIM To evaluate the influence of salivary contamination during dentin bonding procedures on shear bond strength and to investigate the effect of contaminant-removing treatments on the recovery of bond strength for two dentin-bonding agents. MATERIALS AND METHODS Seventy-seven human maxillary and mandibular molars were randomly divided into two groups for total-etch adhesive (Single bond-3M ES...
