Objectives: The purpose of this study was to evaluate the retention rate of fissure sealants with ACP versus sealants with fluoride in MIH molars at 3- and 6-month recalls.
Methods: This split-mouth double-blind trial was conducted in 6-8 years old children with bilateral hypomineralised first molars. Ninety-six hypomineralised molars in 48 children were randomly assigned to one of the two groups: resin sealant with ACP (Aegis®: treatment group) and resin sealant with fluoride (Teethmate-F®: control group). Retention of sealants was evaluated as completely retained, partially lost or completely lost. McNemar test was used to compare the retention rates between groups at 3 and 6 months.
Results: Complete retention rate of 100% was observed in both groups at 3 months. At 6 months, a partial loss of 5 sealants was observed in the treatment group and 3 sealants in the control group, resulting in the retention rates of 89.6% and 93.8% respectively (p = 0.69)
Conclusions: There was no difference in retention rate between resin sealants with ACP and fluoride in MIH teeth at 3 and 6 months. Further studies with longer follow-ups are needed to confirm these results. Supported by Research grants from Graduate School, Khon Kaen University (54211104).
