Objective: To compare retention, preventive effectiveness and longevity of two different highviscosity glass-ionomer sealants Ketac Molar ® and Maxxion R ® in the sealing of erupting and out-of-occlusion first permanent molar in children aged 5-7 years. Material and Methods: Children with past caries experience with healthy erupting first permanent molar were included in the study. Teeth 16 and 46 were sealed with Ketac Molar ® and teeth 26 and 36 were sealed with Maxxion R ®. After 8 months, the retention of sealants was evaluated using the following criteria: total retention; presence of sealant in two thirds of the occlusal surface; presence of sealant in one third of the surface; and total absence of the sealant. Results: Statistical difference between materials was observed, and Ketac Molar ® retention was superior to that of Maxxion R ® (p<0.05). Regarding the development of caries in sealed first permanent molar, none of the teeth sealed with Ketac Molar ® or Maxxion R ® developed caries lesion. Conclusion: Ketac Molar ® retention is significantly superior to that of Maxxion R ® , but the preventive effectiveness in the development of carious lesions is similar for both, which is extremely interesting for the field of public health, since the cost of the material is significantly lower.
Objective: To evaluate the sealing of cavities of dentinal occlusal caries lesions, reproduced in vitro, with flow resin compared to cavity restorations presenting healthy dentin using microhybrid composite resin. Methods: The sample consisted of 27 healthy deciduous molars where cavities of approximately 2 mm in the fossa region were performed and occlusal cleft of each tooth were sealed, impermeabilization was performed and the sample was randomly divided into 2 groups: group I underwent cariogenic challenge and occlusal sealing with resin flow. The teeth of group II were restored with microhybrid composite resin. The teeth were immersed in 5% methylene blue for 8 hours at 37° C and washed until all the dye was removed from the surface. The teeth were sectioned in the mesio-distal direction. The penetration of the dye was evaluated: 0- no penetration; 1- dye penetration up to 1/3 of the restoration; 2- dye penetration up to 2/3 of the restoration depth; 3 - penetration of dye into the pulp wall. The results were analyzed by the Biostat 4.0 program. Descriptive analysis and the mode among the examiners submitted to the Mann-Whitney test. Results: There was no significant difference in microleakage between restoration performed in healthy dentin with microhybrid composite resin or maintenance of infected dentin in primary teeth sealed with resin flow (p = 0.6035). Conclusion: It was concluded that the marginal infiltration of primary molars sealed with microhybrid composite resin and resin flow was not influenced by the removal -or not -of the carious tissue or the material used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
