Abstract:

Aim: Comparative assessment of the wear and preventive effect of two materials – conventional sealant and glass-ionomer cement (GIC), in the coating of sound occlusal fissures of the first permanent molars. Materials and method: The study included 60 teeth in 30 children in the age group of 6 to 9 years. The teeth were diagnosed as “healthy” with code 0 (according to ICDAS II) by visual inspection. The diagnosis was also supported by the SoproLife camera. The teeth were divided into two groups: in 30 teeth the preventive sealing was made with light-curing sealant 3M Clinpro Syringe refill, in the other 30 teeth with GC Fuji IX GP. The follow-up period was 18 months and assessment and comparison of the abrasion of the used materials and their preventive effect was made. Results: According to the criteria used to assess their abrasion, the two materials show similarly very good results over the follow-up period. In both cases there is no loss of the material thickness, which would decrease their preventive effect. No occlusal carious lesion was reported during the observation period. Conclusion: Both materials are equally effective in preventing occlusal carious lesions in newly erupted first permanent molars. The glass ionomer cement used as a preventive sealant is probably the better material for less cooperative children, given its lower sensitivity to moisture when implementing the application protocol.
