Pit and fissure sealants – an update

##Purpose To evaluate evidence on pit and fissure sealants available since the publication: Pit and fissure Sealants: Evidence-based guidance on the use of sealants for the prevention and management of pit and fissure caries (2010) and assess whether there is a need to adapt current practice, considering the Covid-19 pandemic. ##Process Search Strategy: PubMed, Cochrane Library, Guideline International Network and Medline through PubMed databases were searched from January 2010 to June 2020. The guidelines that were used as a basis for the original guideline were also searched for updates. Ninety-six relevant papers were identified. In-vitro studies and review papers were excluded, and the 35 remaining studies were critically appraised, with results from relevant studies tabulated including the strength of the evidence. ##Results 1. Pit and fissure sealants are effective and should be placed on first and second permanent molars. 2. Non-operative cleaning of fissures using a toothbrush or bristle brush is recommended. Mechanical preparation of fissures is not recommended. 3. Patients should be recalled at six-month intervals, or more frequently based on caries risk level. 4. Fluoride application can be considered when pit and fissure sealants cannot be satisfactorily placed and patients recalled within three to six months depending on caries risk level. Further research is required to establish: 5. The use of self-etching agents. 6. The use of a bonding agent when placing sealants. ##Conclusions Processes should be put in place to ensure regular updating of guidelines.
