Bisphenol a absent and hydrophilic pit and fissure resins- a review

Dental caries is one of the most common oral diseases seen in children and Pit and fissure sealants are used as a prophylactic measure to prevent these caries in the pit and fissure surfaces of the posterior teeth.
The pit and fissure sealants are mainly composed of Bisphenol A or BPA based epoxy resins which have an oestrogen like releasing affect and are hydrophobic in nature which requires adequate isolation and moisture control to have the desired effect.
Therefore, recent advances in pit and fissure sealants have been made to reduce and eliminate the unwanted effects. The aim of the review is to study the effects and properties of two newly introduced pit and fissure sealants that are the non-Bisphenol A containing pit and fissure sealants and Hydrophilic pit and fissure sealants.
