statement of problem: pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. resin based ma- terials are the most common materials used worldwide. a variety of resin based fissure sealants are produced and used. most of them have been presented with ideal results in research environment. however, their effectiveness in the real lif...

The ability of uv light-cured fissure sealants to release fluoride ion from different concentrations of sodium fluoride (NaF), over a 3-week period was studied. Two hundred samples of sealant were prepared in which 1 group contained no fluoride (control) and 4 others contained NaF at 0.05, 0.2, 0.5, and 2% concentrations, respectively. The fluoride ion released by each sample after 1 day, 3 day...

Purpose: To evaluate microleakage of pit and fissure sealant after using four different pit and fissure preparation techniques 1) Pumice prophylaxis and acid etching 2) Fissure enameloplasty and acid etching 3) Self etching adhesive system 4) Air abrasion and acid etching. Methods: Eighty exfoliated primary molars with no clinical evidence of caries were randomly divided into 4 groups of 20 eac...

Physical properties such as surface hardness of dental materials are directly linked to their clinical behavior. The aim of this study was to investigate the influence of extended curing time on the polymerization depth offluoride-containing materials used as pit and fissure sealants. Conventional and extended exposure times (20 and 60 seconds) were used to photoactivate a gold-standard pit and...

The clinical behavior of Concise and Prisma Shield sealants for pit and fissure was analyzed by clinical/photographic evaluation. A hematoxylin-based staining solution was applied to the occlusal surface 7 days, 18 months, 36 months, and 11 years after the occlusal sealing, thus allowing the sealant material on the surface to be checked. At each analysis time, each occlusal surface was photogra...

background pit-and-fissure sealants are safe and effective ways to prevent dental caries and are considered as a part of an overall caries-preventive strategy. dental caries are a public health problem and the most common intraoral disease affecting mankind. it is an infectious transmissible disease, with the child patient being at the highest risk. objectives the purpose of this study was to e...

BACKGROUND The success of pit and fissure sealants is directly related to their retention. The purpose of this study was to assess and compare the retention of pit and fissure sealants placed using acid etch alone and a combination of air abrasion and acid etch techniques. MATERIAL AND METHODS 50 subjects aged 6-8 years were included in the study. Primary second molars and permanent first mol...

May/June 2002 This article focuses on the techniques used for successful pit and fissure sealant application by the dental assistant. Pit and fissure sealants first were utilized in 1967 and formally recognized by the American Dental Association in 1971. Since that time, many product developments have been introduced to increase their effectiveness and ease of use. Finding adequate time in the ...

OBJECTIVE Long-term retention of pit and fissure sealants is crucial for their success. This clinical study evaluated the retention rate of a flowable composite resin (Filtek Supreme XT Flowable Restorative) compared to a conventional resin-based sealant (Concise Light Cure White Sealant) over 12 months. MATERIALS AND METHODS Forty subjects aged 6 to 9 years were included in the study. Using ...
