A comparison between three different pit and fissure sealants with regard to marginal integrity

Abstract

Aim:The aim of this study is to compare the occurrence of enamel fractures, sealant fractures and marginal fissures after placement of three sealants: Helioseal F, Conseal F and Clinpro.Materials and Methods:Thirty individuals between 13 and 15 years of age, diagnosed with pit and fissure caries by visual and DIAGNOdent examination, were chosen for sealant placement on their mandibular molars. The sealants were placed at random, after which, impressions were made with polyvinyl siloxane and casts were fabricated. Dies were prepared, each of which were sputter coated with gold in order to be examined under a scanning electron microscope. The following morphologies were analyzed from dies from each of the sealant groups: Continuous margins, sealant fractures, marginal fissures and enamel fractures. After six months, they were recalled for impression making. Dies were prepared and microscopically analyzed as mentioned. Based on the time of evaluation, there were two groups: Initial group (soon after placement) and final group (after six months). Statistical analysis was done using the paired ‘t’ test and One-way analysis of variance (ANOVA).Results and Conclusions:Clinpro had the greatest fracture resistance, followed by Conseal F and Helioseal F. The occurrence of marginal fissure was found to be least with Clinpro.

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

“…Occlusal surface accounts for 12.5% of the total tooth areas of teeth. [ 1 ] Fissure caries is most common in children due to deep pit and fissures. [ 2 ] Pit and fissures are classified as self-cleansable (V and U type) and nonself cleansable (I and k type).…”

“…Unfavorable morphology makes these fissures difficult for salivary access and minimizes fluoride deposition for preventive effect. [ 1 2 3 ] Fissure caries accounts for 50% of all the carious lesions. [ 1 ] Pit and fissures areas on the occlusal surface of the teeth make them susceptible to dental caries which need to be prevented or restored.…”

“…[ 4 5 6 7 ] Simonsen advocated preventive resin restoration to fill the vulnerable fissures with composite sealant after opening with small tapered fissure bur. [ 1 ] Various types of fit and fissure sealants have been suggested such as glass ionomer cement, resin based (filled or unfilled), flowable composite, and fluoride releasing. [ 2 4 8 9 ] Filler content in the sealant increases its viscosity and decreases wear resistance.…”

Effectiveness of Seven Types of Sealants: Retention after One Year

“…Regarding resin-based sealants, our results revealed that unfilled resin sealer Clinpro showed a high retention rate than filled resin sealant Helioseal F. Other studies also concluded the same results. 10,14,24 Low filler content of Clinpro when compared to Helioseal F resulted in low viscosity. 24 Low viscosity of unfilled resin sealant enables it to penetrate deeper in the narrow and irregular anatomy of the fissures.…”

Effect of beverages on surface properties of resin-based sealants

“…Sealants have been the subject of numerous studies evaluating effectiveness, adaptation and penetration into fissures and fluoride release 4,9 . In the oral environment, dental material is also subjected to chemical and physical insults.…”
