Pit and fissure sealants are thin, protective coatings applied to the grooves of back teeth to prevent dental caries, especially in children and adolescents.What they are and why used Pit and fissure sealants are flowable materials placed mainly on the occlusal surfaces of premolars and molars to block food and bacteria from collecting in deep pits and grooves. These areas are more prone to decay than smooth surfaces because they are harder to clean and receive less protection from fluoride.Types of sealant materials The two main categories are resin‑based sealants and glass ionomer sealants. Resin‑based sealants are usually preferred for their better retention, while glass ionomer sealants are useful when moisture control is difficult and provide fluoride release over time.Indications and effectiveness Sealants are recommended for newly erupted permanent molars and premolars with deep or stained fissures, especially in patients at moderate or high caries risk and without obvious cavitated lesions. When properly placed and maintained, sealants significantly reduce occlusal caries, with long‑term studies showing high success rates where retention is maintained.Basic application steps Typical clinical steps include cleaning the tooth, isolating it from saliva, etching the enamel (commonly with 37% phosphoric acid), rinsing and drying, applying the sealant to all susceptible pits and fissures, then light‑curing and checking occlusion. Adequate isolation and avoiding salivary contamination are critical because moisture greatly reduces retention of traditional hydrophobic resin sealants.Newer developments Newer moisture‑tolerant (hydrophilic) resin sealants have been developed to improve performance when perfect dryness is hard to achieve, such as in erupting molars. These materials aim to combine good retention with easier clinical handling and, in some products, bioactive or fluoride‑releasing properties. advances in pit and fissure sealants advantages and disadvantages of pit and fissure sealants advantages of pit and fissure sealants application of pit and fissure sealants application of pit and fissure sealants for dental assistants armamentarium for pit and fissure sealants benefits of pit and fissure sealants best pit and fissure sealant material best pit and fissure sealants classification of pit and fissure sealants colored pit and fissure sealants commonly used pit and fissure sealants composition of pit and fissure sealants contraindications of pit and fissure sealants cost effectiveness of pit and fissure sealants cost of pit and fissure sealants curing time for pit and fissure sealants definition of pit and fissure sealants dental pit and fissure sealants how long do pit and fissure sealants last how to apply pit and fissure sealants how to do pit and fissure sealants how to place pit and fissure sealants how to use pit and fissure sealant ideal properties of pit and fissure sealants if a hygienist places pit and fissure sealants the dentist indications for pit and fissure sealants indications of pit and fissure sealants is pit and fissure sealants ivoclar pit and fissure sealants new pit and fissure sealants pit and fissure sealant application steps best dental clinic in south delhi best dental clinic south delhi best dental implants in south delhi best dental in south delhi best dental surgeon in south delhi dental clinic near me english dental clinic near me indian dental clinic south delhi dental implants cost in south delhi dental implants south delhi dentist south ex dentists in south delhi where is dental clinic near me who is the best dentist in delhi why dental treatment so expensive in india
