BACKGROUND This article presents evidence-based clinical recommendations for use of pit-and-fissure sealants developed by an expert panel convened by the American Dental Association Council on Scientific Affairs. The panel addressed the following clinical questions: Under what circumstances should sealants be placed to prevent caries? Does placing sealants over early (noncavitated) lesions prev...

INTRODUCTION The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample. MATERIALS AND METHODS A cro...

Introduction: The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample.

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 ...

We evaluated the concentration of fluoride release at the initial stage and after recharging the fluoride from a resin-based sealant containing surface reaction-type pre-reacted glass-ionomer (S-PRG) filler and conventional resin-based sealants. The concentration of other ions released from the sealants in the surrounding distilled water was also examined. At the initial stage, fluoride was rel...

Sealants are highly effective in preventing dental caries in the pits and fissures of teeth. It has been shown, however, that sealants are not widely used by dentists. This study aimed to educate dental professionals about sealants and to evaluate the effect of such education on dentists' knowledge, attitude and use of sealants. A total of 312 dentists were surveyed to determine their knowledge...

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...


 Three guidelines recommend the use of dental sealants to prevent or manage caries in children and adolescents. Sealants may be used as a preventive measure upon eruption molars, treatment arrest reverse noncavitated carious lesions. alone combination with other treatments that protect against tooth decay.
 Overall, were rigorous, comprehensive, clearly reported, but there gaps guida...

allow three different levels of carbon dioxide to be maintained, with identical plants grown in each section. Broecker said they are looking at conducting long-term experiments (perhaps decades-long) that emphasize perennial plants. They will look at factors such as the quality of fruits and nuts, as well as water-use efficiency. Many questions remain about what experiments to conduct, what pla...
