Application of glass ionomer and light-cured resin sealant to the pit and fissure of deciduous teeth / 中国组织工程研究

ABSTRACT

BACKGROUND: Traditional glass ion sealant has a poor abradability and a low rupture strength. The sealant on the occlusal surfaces easily fell off, and is difficult to replace resin sealant. OBJECTIVE: To observe the effects of traditional resin sealant and atraumatic restorative treatment (ART) glass ionomer-based pit and fissure sealant for the young children. METHODS: Randomized comparison method was used to compare ART glass ionomer-based pit on molars of one side with resin sealant on the opposite side in 89 3-year-old children. RESULTS AND CONCLUSION: The retention rates of ART glass ionomer sealant after 6 and 18 months were significantly lower than those of resin sealant (P < 0.05). The caducous position of ART gliass ionomer sealant was the second deciduous molar of the lower mandible, but the caducous position of resin sealant was the second deciduous molar of the upper mandible. The secondary caries rate of ART glass ionomer sealant was significantly lower than that of resin sealant at 6 months. No significant difference was determined between groups at 18 months. These suggest that ART glass ionomer pit and fissure sealant has lower drop-out rate, simple operation and low cost with excellent caries-preventing effect. Since it is economically superior to resin sealant, the method is worth popularizing in caries-preventing projects.
