Can government-supported preventive fluoride varnish application service reduce pulp-involved primary molars?

摘要: OBJECTIVES Fluoride varnishes are reported to reduce 37-43% of dental caries; however, it remains unclear whether they can prevent severe decay. The study investigated the association between government-supported preventive fluoride varnish application service (FVAS) and risk undergoing treatments pulp-involved primary molars. METHODS Children who were younger than 6 years did not receive any treatment first last services within 2 years defined as "preventive-FVAS group." After matching process, 45,296 children selected for further analysis until end 2013. log-rank test Cox proportional hazard models employed estimate effects preventive-FVAS on molars, including pulpectomy early extraction before age 8 years. RESULTS adjusting confounding factors, adjusted ratios molars received 0.96 (95% CI = 0.92-1.00) initiation pulpectomy, 0.93 CI = 0.86-1.00) completion 0.87 CI = 0.82-0.92, P < 0.0001) extraction, especially those three or more FVAS. CONCLUSIONS Although preventive-FVASs associated with a 4-13% decreased lower subset, we suggest implementation current Taiwan FVAS program needs be modified. Further studies warranted evaluate would better strategy if focused only high-risk group.
