Hybrid Glass Material and Injectable Composite: Dental Sealants Trials

Objectives: Dental care prevention best practices in the "Accessible Health Initiative" involve four aspects: (1) healthy diet; (2) good oral hygiene; (3) use of fluoride toothpaste and (4) pit and fissure sealants. These aspects focus on preventive dental care based on the early detection of the disease. Thus, the objective of the present clinical evaluation was to investigate the effect of a hybrid material of glass and high-strength injectable composite in fissures of permanent molars by the ART technique on retention rates and incidence of caries during a period of 6 months in a public school Brazilian from a low-income community.
Methods: 68 dental sealants were made using Equia Forte-GC Corporation (Group 1) on one side of the mouth and GC G-ænial™ Universal Injectable-GC Corporation (Group 2) on the other side, in 17 participants. Restorations were evaluated at 6 months using modified United States Public Health Service (USPHS) criteria. Akaike Information Criterion (AIC) and Likelihood Ratio Test (p<0.05) were used for statistical analysis.
Results: The seven-year-old girls presented 25% of failures, while the older ones 100% of successes. Boys had equal proportions of successes and failures at 7 years of age, at more advanced ages an increase in successes is observed, but percentages above 25% of failures are still observed at 8 and 9 years of age. Still, in general, the percentage of failures in group 2 was slightly higher than that of group 1. When considering boys, group 2 had a much higher percentage of failures when compared to group 1. In general, except for the age of 7 years, there is an increase in the percentage of correct answers for both groups.
Conclusions: The younger the age, the greater the chance of failure, and the ionomeric material was more effective than the resin material.
