A Two-Year Clinical Evaluation of Fluoride and Non-Fluoride Resin-Based Pit-and-Fissure Sealants

Clinical success of fluoride-releasing fissure sealant in permanent first molars: 5-year retrospective atudy

Background/Aim: It is important to prevent caries on permanent first molars. Fissure sealants are very effective in protecting fissures from caries. The study aimed to determine the clinical success of fluoride-releasing fissure sealants in permanent first molars in the long term. Material and Methods: 64 children with 256 healthy erupted first permanent molars and followed for 5 years, comprised the study. Children who received a fluoride-releasing fissure sealant and came regularly to controls throughout 5 years were evaluated by retention rate and development of new caries and compared with a control group. Results: The complete retention rate of fluoride-releasing fissure sealants was 48.5% and 10.7 % of the sealed teeth had caries after 5 years. 25% of the teeth without fissure sealant were decayed after five years. There was no significant difference between the rate of retention of fissure sealants and the frequency of tooth brushing after 1 year. There was no significant difference between the rate of retention of fissure sealants and oral hygiene status of children after 1 year. Conclusions: The fluoride-releasing fissure sealants were effective for the prevention of caries on pit and fissures of permanent molars and long-term clinical success was satisfying.

In vitro evaluation of shear bond strength and microleakage of different pit and fissure sealants

Aim and Objectives:

Fissure caries is most common in children due to deep pit and fissures. Pit and fissure areas on the occlusal surface of the teeth make them susceptible to dental caries, which need to be prevented or restored. Fissures sealant reduces the risk of occlusal caries. The present study was done to evaluate microleakage and shear bond strength of various fissure sealants.

Materials and Methods:

Thirty-six extracted molars were randomly allocated equally (n = 12) into three groups with three different sealants to evaluate shear bond strength and microleakage at sealant space. The shear bond strengths was evaluated with one-way analysis of variance and microleakage by Kruskal-Wallis nonparametric test using the Statistical Package for the Social Sciences version 18.0 (Chicago: SPSS Inc, 2009).

Results:

Tetric flow (16.8 MPa) recorded the highest shear bond strength and the difference was statistically significant with enamel loc (12.8 MPa). There was no statistically significant difference in relation to microleakage (P > 0.05) in the tested groups.

Conclusions:

Tetric flow recorded the highest shear bond strength and the difference was statistically significant with enamel loc. However, there was no statistically significant difference among the groups regarding microleakage.
