The study aimed to assess the clinical evaluation of two different types of pit and fissure sealants after treating with two different remineralizing agents in preventive resin restorations.

Primary objectives:

Assessment of retention rate and marginal integrity of two types of pit and fissure sealants when using two types of remeneralizing agents using Ryge's criteria and Simonsen's criteria.

Secondary objectives:

Assessment of stability of results after 3, 6 and 9months.

Dental caries is one of the most common intraoral diseases, with serious consequences for both the individual patient and for the public in terms of medical, social, and economic concerns. The individual patient suffers from pain, dysfunction of the oral system, and reduced quality of life.

Caries predominantly attack the occlusal surfaces of premolars and molars during their eruption . On the other hand, smooth surface caries have shown a significant decline, likely a result of increased worldwide access to fluoride . In previous reports, an incomplete post-eruptive maturation , and the presence of narrow and deep fissures were blamed for the increased caries susceptibility of occlusal surfaces . It has been more than 40 years since the pit and fissure sealants were first used clinically. During this time, pit and fissure sealants have been shown to be effective in reducing the risk of occlusal caries . A study aimed to evaluate the effect of the previous application of a casein phosphopeptide-amorphous calcium phosphate paste (MI Paste, MI) and adhesive systems on the bond durability of a fissure sealant. Ninety-eight enamel blocks were obtained from proximal surfaces of erupted third molars.

Anthor study evaluated the effect of treating the enamel with topical fluoride gel prior to acid etching on sealant retention clinically (Part I) and in vitro (Part II). Results showed no statistically significant differences between the test and control groups either clinically or in vitro. It is concluded that topical fluoride application prior to acid etching does not have a deleterious effect on sealant retention .

The study aimed to assess the clinical evaluation of two different types of pit and fissure sealants after treating with two different remineralizing agents in preventive resin restorations.
