BACKGROUND: The association between light-polymerised resin-based fluoride-releasing sealants and pit-and-fissure caries on primary molars is unclear.
AIM: To investigate the efficacy of resin-based fissure sealants in preventing caries on primary molars.
DESIGN: In this retrospective study of patients attending a tertiary dental hospital for at least 30 months, records of 106 children (275 teeth) were reviewed. Sealant placement on primary molars in the outpatient clinic (OPC) and under general anaesthesia (GA) was recorded, measuring caries incidence over time.
RESULTS: Of the 275 teeth, 94 (34.2%) developed caries during this period. Among those carious teeth, 17 teeth (18.1%) were sealed compared to the 77 (81.9%) non-sealed (p < 0.001). In molars that developed caries, those sealed under GA were associated with longer caries-free mean duration compared to the non-sealed molars (3.07 years compared with 2.32 years, respectively, p < 0.001). Among teeth sealed in OPC, one tooth developed caries. An adjusted hazard ratio of 0.048 (95% CI: 0.025-0.090, p < 0.001) demonstrated a 95.2% lower hazard of caries development in the sealant group compared to the non-sealant group.
CONCLUSION: Sealed primary molars are less likely to develop pit-and-fissure caries in OPC and GA, with a substantial long-term protective effect observed in the GA-treated group.
