Clinical Analysis of Three Different Sealing Materials

The aim of the study was to evaluate clinically the retention rate of different dental materials, used as fissure sealants, over a 12-months period. The study sample was made up of 73 patients. 150 healthy permanent molars were randomly divided into three groups and sealed with three different dental materials. 48 teeth were sealed with Teethmate F1 (Kuraray), 52 teeth were sealed with Helioseal Clear Chroma (Vivadent) and 50 teeth were sealed with Tetric Flow (Vivadent) sealing material. The retention rate and secondary carious lesions were assesed following the criteria proposed by Kilpatrick et al (1996.): 0-total retention, 1-partial loss of 1/3 of sealant, 2-partial loss of 2/3 of sealant, 3-total loss (more than 2/3 of material). Secondary carious lesions were evaluated following these criteria: 0-no carious lesion, 1-carious lesion. Over a 12-months period, the total retention for Teethmate F1 was 77.1%. For Helioseal Clear Chroma the retention rate was 76.9% and for Tetric Flow sealing material the rate was 84%. Although the retention of Tetric Flow sealing material was greatest, the difference is not statistically significant (p=0.287). In the group of 150 sealed teeth, carious lesions could be found only in 3 teeth ; 2 in the group sealed with Teethmate F1 and 1 in the group sealed with Helioseal Clear Chroma. No carious lesions were observed in teeth sealed with Tetric Flow. These results show that the retention rate of flowable composite, used as fissure sealant, is better compared with conventional fissure sealing materials, but the difference is not statistically significant. Low incidence of carious lesions at fissure sealings shows optimal preventive function of sealing materials.
