Use of Pit-and-Fissure Sealants.
BACKGROUND This article presents evidence -based clinical recommendations for the use of pit- and -fissure sealants on the occlusal surfaces of primary and permanent molars in children and adolescents . A guideline panel convened by the American Dental Association ( ADA ) Council on Scientific Affairs and the American Academy of Pediatric Dentistry conducted a systematic review and formulated recommendations to address clinical questions in relation to the efficacy , retention , and potential side effects of sealants to prevent dental caries ; their efficacy compared with fluoride varnishes ; and a head-to-head comparison of the different types of sealant material used to prevent caries on pits- and -fissures of occlusal surfaces . TYPES OF STUDIES REVIEW ED This is an up date of the ADA 2008 recommendations on the use of pit- and -fissure sealants on the occlusal surfaces of primary and permanent molars . The authors conducted a systematic search in MEDLINE , Embase , Cochrane Central Register of Controlled Trials , and other sources to identify r and omized controlled trials reporting on the effect of sealants ( available on the U.S. market ) when applied to the occlusal surfaces of primary and permanent molars . The authors used the Grading of Recommendations Assessment , Development , and Evaluation approach to assess the quality of the evidence and to move from the evidence to the decisions . RESULTS The guideline panel formulated 3 main recommendations . They concluded that sealants are effective in preventing and arresting pit- and -fissure occlusal carious lesions of primary and permanent molars in children and adolescents compared with the nonuse of sealants or use of fluoride varnishes . They also concluded that sealants could minimize the progression of non-cavitated occlusal carious lesions ( also referred to as initial lesions ) that receive a sealant . Finally , based on the available limited evidence , the panel was unable to provide specific recommendations on the relative merits of 1 type of sealant material over the others . Conclusions and practical implication s : These recommendations are design ed to inform practitioners during the clinical decision-making process in relation to the prevention of occlusal carious lesions in children and adolescents . Clinicians are encouraged to discuss the information in this guideline with patients or the parents of patients . The authors recommend that clinicians re-orient their efforts toward increasing the use of sealants on the occlusal surfaces of primary and permanent molars in children and adolescents
