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...

The penetration coefficients (PCs) and tensile bond strengths of eight pit and fissure sealant materials were determined. The PCs were tested at 22°C with five samples of each resin. Bond strengths were established in a tensile mode using an Instron * testing machine with 10 specimens for each sealant. Despite considerable variation in the PC values, all sealants showed similar tensile bond str...

Background/Aim: It is important to prevent caries on permanent first molars. Fissure sealants are very effective in protecting fissures from caries. The study aimed determine the clinical success of fluoride-releasing fissure molars long term. Material and Methods: 64 children with 256 healthy erupted followed for 5 years, comprised study. Children who received a sealant came regularly controls...

PURPOSE The purpose of this study was to evaluate the clinical effect of topical fluoride on retention of light-cured (CLC) and self-cured (CSC) pit and fissure sealants. METHODS CLC and CSC sealants were placed in vivo on opposite sides of the arch before and after fluoride treatment. A total of 122 sealants were placed on virgin permanent molars and premolars of 16 dental hygiene students e...

AIM Dental caries in pits and fissures of molars is still very common in young people, despite a gradual reduction in their incidence and prevalence. Prevention with the aid of dental fissure sealants can help to reduce the onset of decay. In vitro tests were conducted to compare the bond strength to enamel of self-etching sealants versus those applied using the conventional procedure. METHOD...

PURPOSE The null-hypothesis that retention loss of resin fissure sealants predicts caries manifestation no more accurately than random values was tested. METHODS Systematic reviews were checked and electronic databases searched for clinical trials. Trials reporting on the retention of resin sealants and caries occurrence in permanent molar teeth, with minimum 24-month follow-up period, were i...

The use of sealants and sealant restorations has increased considerably over the past 10 years, and with it increased the problem of detecting secondary caries and marginal (micro)leakage. It was the purpose of this study to investigate the validity of electrical conductance measurements (ECMs) in diagnosing marginal leakage into dentine of sealants and sealant restorations. Ninety extracted pr...

It is now ten years since a 'ventral language pathway' was demonstrated in vivo in the human brain. In the intervening decade, this result has been replicated and expanded to include multiple possible pathways and functions. Despite this considerable level of research interest, age-old debates regarding the origin, course, termination and, indeed, the very existence of the tracts identified sti...
