Pit And Fissure Sealant

Background: Pits and fissure sealants are widely used to prevent caries in children. Microleakage is one of the most crucial factors resulting in sealant compromise. Factors pertaining to microleakage like, pre-treatment of occlusal surfaces, moisture control, bonding systems, and flowability of the sealant, will determine the longevity of the treatment. In vitro microleakage studies are useful in predicting the marginal sealing ability of pit and fissure sealants. Aim: This in vitro study was undertaken to evaluate and compare the microleakage of ACP (Aegis®) containing pit and fissure sealant and moisture tolerant pit and fissure sealant (EmbraceTM WetbondTM). Study Design: In vitro study. Place and Duration of Study: Department of Pedodontics and Preventive Dentistry, Dr. D.Y. Patil Dental College and Hospital, Pune. between June 2020 and February 2021. Methodology: 26 permanent non- carious premolars extracted for orthodontic treatment were used. The sealants used for the analysis of microleakage were Aegis® and EmbraceTM WetbondTM pit and fissure sealants. The premolars were divided into two groups of 13 each. After sealant application, they were immersed in methylene blue dye. The teeth were subjected to thermocycling for 24 hours, after which The teeth were sectioned buccolingually and dye penetration was studied under a stereomicroscope (magnification 10X). Results: Both the groups were studied and statistically evaluated using Mann- Whitney U test. Aegis® showed higher microleakage in (46.2%) than Embrace (38%), though the results were not statistically significant. Conclusion: Both the materials showed microleakage, more In-vivo studies with longer follow- up periods are needed to evaluate and compare the clinical success of these pit & fissure sealants.

Background and aims. Pit and fissure sealant placement corresponds to an effective approach of the prevention of caries on occlusal surfaces. Fissure morphology and dental material characteristics are the key factors for sealant effectiveness. The aim of this in vitro study was to compare the penetration ability of two commercially available pit and fissure sealants. Methods. Twenty sound human premolars extracted for orthodontic purpose have been sealed according to manufacturer’s instructions as follows: Group I (n=10), light-cured unfilled resin-based sealant, Admira Seal® (Voco GmbH); Group II (n=10), resin modified glass ionomer sealant without varnish, GC Fuji Triage® (GC Corporation). The teeth have been sectioned buccal-lingually in the middle of the occlusal surface, and the sections were examined at 40x with an inverted microscope. Results. Penetration of the sealants was found to be greater in U-type fissure pattern (91.69%) followed by V-type (75.42%), IK-type (71.24%) and then in I-type (63.98%). The depth of penetration of GC Fuji Triage® (82.85%) demonstrated to be superior to Admira Seal® (76.28%). Conclusion. U fissure design was more common than other fissure patterns and showed significantly higher penetration for the two type of sealants evaluated. Resin modified glass ionomer sealant used in the present study perform comparably with the filled resin sealant.

The purpose of modern dental medicine is to prevent dental caries and promote minimally invasive techniques at the expense of invasive methods. Dental sealants are largely recommended for occlusal surfaces protection, but concerns are related about microleakage at material-enamel interface. This in vitro study aimed to investigate the association between chemical structure, sealing capacity and marginal infiltration for 2 fluoride F containing commercially available resin-based sealants: Pit&Fissure� Sealant (DMP) and Fissurit FX� (Voco) in order to achieve a better description and ensure adequate material selection in every day practice. An optimal resin-based sealant should mimic the structural, physical and mechanical characteristics of enamel. The main difference between the sealing materials tested is based on the amounts of inorganic filler and on the various shapes of the particles in the filler. Pit&Fisure� Sealant express less attachment at enamel interface, higher sorption and greater water solubility, when compared to Fissurit FX�. The better sealing capacity of Fissurit FX� can be described by the homogeneity of the material and the very small size of the inorganic fillers. Dental materials properties used as pit and fissure sealants are sensitive to mechanical, thermic and chemical stress from oral cavity. Regular dental check-up can detect the presence and integrity of sealant and ensure preventive effect in time.

<p><span>The objective of this study was to evaluate the marginal seal effectiveness and microleakage of a pit and fissure sealant containing silver nanoparticles (AgNPs). An experimental in vitro study was carried out using 40 extracted temporary molars without caries or incipient caries. These molars were divided into two groups: Group A (20 molars), to which a silver nanoparticle-containing sealant was applied, and Group B (20 molars), to which a conventional sealant was applied. The marginal seal and microleakage were evaluated. No significant differences in the marginal seal or microleakage were noted between the silver nanoparticle-containing sealant and the conventional sealant.The addition of AgNPs does not alter the adhesion or resistance of the sealant. </span></p>
