This paper reviews the recent evidence and discusses the development of pits and fissure sealants in dental practice. It also, covers the different factors affecting the retention of resin sealants in paediatric dentistry, the cost-effectiveness, and the economic implications of dental sealants in high caries risk children as well as the optimal time to review fissure sealants. It was concluded from this review that resin sealants by far is the most effective method in preventing occlusal caries and arresting its progression in high caries risk children. Also, it was evident that the success of resin sealants retention depends on multiple factors and its application considered a technique sensitive and required multiple clinical steps. Therefore, caries risk assessment prior to sealant application was recommended for optimal cost- effectiveness. Lastly, incorporating regular review of sealed teeth as a part of the child’s recall visits is crucial to ensure maximum retention and to maintain its caries preventive effect.48enFissure sealantsCariesRetentionThesis
