In Germany, the application of resin-based pits and fissures sealants on the occlusal surfaces of permanent molars is part of individual prophylaxis for children and adolescents between six and 18 years. The individual prophylaxis is covered by the Statutory Health Insurance since 1993. The report addresses questions on medical effectiveness, cost-effectiveness, as well as ethical, social, and ...

PURPOSE The purposes of this study were to: (1) evaluate the ability of a laser fluorescence (LF) unit to detect simulated caries under pit and fissure sealants; (2) determine the effect of an opacifying agent in sealants on LF values; and (3) determine interexaminer reproducibility values of the unit in a highly controlled, laboratory setting. Sealant characteristics specifically considered we...

OBJECTIVE The aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles. MATERIALS AND METHODS This in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-TCP nanoparti...

background and aims. marginal seal of the material is extremely important in fissure sealant therapy. the aim of this study was to investigate microleakage of flowable composite resins and conventional fissure sealants with or without dentin bonding agent. materials and methods. the occlusal surface of 60 intact extracted human premolars, divided into four groups, were cleaned with pumice/slurr...

BACKGROUND The incorporation of fluoride into sealants has been viewed as a viable way to prevent pit-and-fissure caries by potential inhibition of demineralization through the release of fluoride to enamel. The authors conducted a study to examine the effect of a recently introduced fluoride-releasing sealant (ProSeal, Reliance Orthodontic Products, Itasca, Ill.) on enamel demineralization in ...

BACKGROUND The long-term capability of resin sealants and glass ionomer cements to release fluoride is associated to a reduction in pit and fissure caries. The regular use of fluoride varnishes/toothpastes can result in the absorption of fluoride into the sealant. The objective of the present study was to assess the fluoride release/uptake capacities of different fissure sealants. MATERIAL AN...

background: a prolonged life of fissure sealant has always been the target for preventing caries in vulnerable newly erupted teeth. the use of preparatory techniques including bur introduction to the fissures is considered among such improving steps. the aim of this investigation was to compare the microleakage level of fissure sealants prepared by a fissurotomy bur or pumice prophylaxis prior ...
