BACKGROUND: Increased dental caries and dental lesions have made preventive measures, especially among children, inevitable. This study investigated elementary schoolgirls’ mothers’ level of knowledge on preventive methods against dental caries. METHODS: In this cross-sectional study, mothers of 250 schoolgirls were randomly selected from five regions of Tehran, Iran. Their knowledge about fiss...

INTRODUCTION Optimal pit and fissure sealing is determined by surface preparation techniques and choice of materials. The performance of pit and fissure sealant materials has been intensively investigated, yet no single product is reported as an ideal sealant. In children, moisture control during cavity preparation is always a big challenge, and hence, hydrophilic sealants have been developed. ...

PURPOSE The purpose of this study was to evaluate the retention rate and the caries increment differences between a light cured, F releasing filled fissure sealant and a non-F nonfilled one. METHODS The two different fissure sealants (Fluoroshield, Delton) were placed on all 4 caries-free first permanent molars of 112 children aged 7-8 years, under a half-mouth experimental design. All the ch...

OBJECTIVE To compare the retention and the caries preventive effect of a glass-ionomer developed for fissure sealing (Fuji III) and a chemically polymerized resin-based fissure sealant (Delton). DESIGN A split mouth randomized design using contralateral teeth. SETTING WHO Regional Demonstration, Training and Research Center for Oral Health, Damascus, Syrian Arab Republic. SAMPLE AND METHO...

PURPOSE The aim of this work is to study and compare the retention rate, caries-preventing and antibacterial effects of resin-modified glass ionomer and flowable composite in comparison to conventional fissure sealant. METHODS Forty-five children aged 7-10 years with newly erupted lower first permanent molars were randomly divided into three equal treatment groups. Group I: sealed by a conven...

The clinical effectiveness of a self-polymerized fissure sealant was studied, in 205 children, ages 6-10 years (mean age 71⁄2 years). There were 313 sites sealed and after four and six years, 247 and 115 were available for recall After four years, sealant retention was 73 % and effectiveness in caries reduction was 77%. After six years, 58% of sealants were retained and these were 56 % effectiv...

Retention of fissure sealant in deep pits and fissures of molar is the main criteria for successful prevention of occurrence of dental caries. These fissure sealants are subjected to various factors like oral hygiene practices and dietary habit that differs from place to place. So a study was conducted to evaluate and compare the retention rate of the flowable composite resin sealant among the ...

Glass Carbomer is a new generation of restorative material developed from glass-ionomer cements with possibility of gradual mineralization into fluorapatite. The aim of this clinical trial was to investigate the retention of Glass Carbomer fissure sealant after 12 months, in comparison to a commonly used conventional resin-based sealant. Forty-eight teeth in 24 patients [mean (SD) = 8 (2.3) yea...

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. MATERIALS AND METHODS Ninety freshly extracted healthy maxillary premolar teeth were randomly selected for this investigation. Teeth were then di...

PURPOSE The purpose of this in vitro study was to determine the effect of different cleaning methods and the use of post-etching drying agents, as well as the influence of fissure types on the microleakage and penetration ability of fissure sealants. METHODS Ninety extracted human molar teeth were randomly divided into 9 groups of 10 each. The treatment groups were defined by the combination ...
