Aim: Comparative assessment of the wear and preventive effect of two materials -conventional sealant and glassionomer 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 lightcuring 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.
The aim of this review is to summarize biological products -plasmotherapy for regenerative endodontic therapy.Plasmotherapy (part of tissue engineering) is a relatively new method in medicine that stimulates the healing of hard and soft tissues by significantly relieving pain. The mechanism of action of bioproducts for plasmotherapy are considered, as well as the types of plasmotherapy products and protocols for their application.
