PURPOSE This in-vitro study evaluated shear bond strength and analyzed, via scanning electron microscopy, enamel prepared for pit and fissure sealant placement. Various surface pretreatment methods were conducted prior to short-term (72-hour) and long-term (120-day) analysis. METHOD Six treatment groups of 14 teeth, having 28 bonding surfaces (buccal and lingual) were treated. Cylinders of De...

PURPOSE The purpose of this in vitro study was to evaluate microleakage of pit and fissure sealants after using three different pit and fissure preparation techniques: (1) traditional pumice prophylaxis and acid etching, (2) fissure enameloplasty and acid etching and (3) air abrasion and acid etching. METHODS Sixty extracted third molars with no clinical evidence of caries were randomly divid...

PURPOSE The objective of this study was to compare the effect of phosphoric acid and a self-etching adhesive on the short and long-term bond strength of a light-curing sealant to unground primary and permanent enamel. METHODS A light-curing resin sealant (Delton Light Curing Pit & Fissure Sealant-CLEAR) was bonded to the flattest, peripheral surface of 40 primary and 40 permanent molars follo...

Background: Sealant therapy is the safe and effective way to prevent dental caries in newly erupted teeth. Success of sealant therapy depends on the good isolation, patient corporation and the decrease step for the application of sealant. Aim: Comparative evaluation of marginal microleakage of conventional fissure sealants and self-adhering flowable composites as fissure sealant in permanent te...

A double-blind randomized clinical trial was performed in 6- to 7-yr-old schoolchildren to evaluate, in a 30-mo period, whether the caries increment on the distal surface of the second primary molars adjacent to permanent first molars sealed with fluoride release compounds would be lower with respect to those adjacent to permanent first molars sealed with a nonfluoridated sealant. In sum, 2,776...

This study was performed to examine the success of a conservative cavity preparation using the principle of "sealing for prevention" rather than "extension for prevention." A total of 332 restorations were placed in 243 permanent molars in 114 children aged 6-14 with a mean age of 8 years. After 80 months, 104 restorations were examined for sealant retention, marginal staining, anatomic wear, m...

Arresting occlusal enamel caries lesions with pit and fissure sealants The aim of this study was to evaluate the feasibility of pit and fissure sealants and the effectiveness of the two sealant methods applied in every-day practice in public dental health care in Finland. Two sealant methods were evaluated according to their effectiveness in preventing dentin caries at occlusal surfaces and sea...

PURPOSE This study investigated the influence of sealant application on stain resistance of a nanohybrid resin composite compared to the efficacy of a bonding agent used as a surface sealant on prolonging color stability of the resin composite. MATERIALS AND METHODS 28 disc-shaped materials were prepared from a nano-hybrid resin composite Filtek Z550 and assigned to four groups: G1K: nonseale...

BACKGROUND Fibrin sealants are widely used in liver surgery. The aim of this article is to review the literature on evidence of hemostatic and biliostatic capacities of different fibrin sealants in liver surgery. METHODS In PubMed, a literature search was done with the search terms 'fibrin sealant' or 'fibrin glue' combined with 'liver resection' or 'bile leakage'. Thirteen comparative fibrin...
