There are no published research reports on the prevalence of dental sealant use in children in Saudi Arabia. This study determined the prevalence and socioeconomic indicators of dental sealant use on the permanent molars of a stratified random sample of schoolchildren in Jeddah. A basic oral screening survey of students was conducted by dentists and a self-administered questionnaire was complet...

PURPOSE The purpose of this study was to evaluate the effect of material characteristics, preparation techniques, and fissure morphology on the microleakage and penetrability of pit and fissure sealants. METHODS Sealants used in the study included: (1) Aegis; (2) Conseal f; (3) Admira Seal; (4) Triage; and (5) Delton Opaque. A total of 100 extracted permanent molars were randomly assigned to ...

BACKGROUND Marginal seal has a principal role in durability and clinical success of fissure sealants. The aim of this study was to compare the microleakage of two materials used as pit and fissure sealant with different methods of application. METHODS The 55 extracted premolars were assigned randomly to one of the following five groups: Group 1: Acid-etching (ultra-etch) + fissure sealant (co...

Dental sealants are important for prevention of carious lesions, if they have good shear strength. The aim of this study was to evaluate the shear bond strength (SBS) of two sealants to saliva-contaminated and non-contaminated enamel with and without an intermediate adhesive layer underneath the sealant. Ninety flat enamel surfaces from human third molars were randomly assigned to 6 groups (n=1...

The effect of sealant placement and sealant loss on caries-like lesion formation was studied using an artificial caries technique and polarized light microscopy. The results indicate that lesion formation does not occur subjacent to an intact sealant. Even enamel which had lost is sealant was found to be caries-free. It is concluded that resin tags may be responsible for the ability of sealants...

Introduction: It was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. Materials and methods: A randomized parallel designed study was conducted with 352 child-ren aged 6-7 years. Participants were allocated into biannual application of varnish (n=179) (NaF 5 %( Durafluor, DENTSPLY®, Latin America) or re...

OBJECTIVE To test a novel hydrogel sealant to secure sutureless sclerotomies under variable intraocular pressure conditions. METHODS In cadaver eyes, 23- and 20-gauge (G) sclerotomies were constructed. Sixteen 23-G beveled sclerotomies were constructed in 4 eyes: 8 of the incisions were treated with hydrogel sealant, while 8 were left bare. All sclerotomies were monitored for leaks while the ...

recently, self-etching fissure sealants have been introduced to reduce technical sensitivity; however, their efficacy should be assessed. the aim of this study was to assess of the microshear bond strength of self-etching and conventional fissure sealants.thirty non-carious third molars were randomly divided into three groups (n=10). microcylinders of concise fissure sealant were bonded to prep...

A variety of pit and fissure sealants are used clinically to protect the occlusal surfaces of teeth against dental caries. A new chemically activated bis-GMA type sea­ lant, Delton Pit and Fissure Sealant, has recently be­ come commercially available. The Delton Etching So­ lution supplied with the sealant contains 35 per cent orthophosphoric acid. The tensile bond strength of this sealant to e...
