简要总结
Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs. Various preventive strategies for dental caries have been tried and are still being developed. The occlusal pits and fissures of posterior teeth are highly susceptible to caries because of the anatomy of pit and fissure surfaces, which favours stagnation of bacteria and substrates. Fissure sealing has been shown to be an evidence-based caries preventive method for protecting the occlusal surfaces against caries. Non- sealed teeth need to be restored approximately 50% more frequently compared to their sealed counterpart. Sealants are effective caries preventive agents as long as they remain bonded to teeth.
It has been proposed that sealants should be placed on both sound teeth and incipient non-cavitated carious lesions on permanent teeth of high caries risk patients in order to prevent the onset of caries and its progression. According to the American Dental Association Guidelines for the use of pit and fissure sealants, ICDAS II codes 0, 1 and 2 are recommended for sealant application.A variety of dental materials have been used as sealants using different application techniques. Their effectiveness depends on the formation of a complete seal and is increased by correct technique and moisture control, appropriate follow-up and resealing as necessary. Resin-based conventional sealants are preferred choice, however use of phosphoric acid demineralizes the enamel layer and have elongated treatment time and is more technique sensitive.

It has been proposed that sealants should be placed on both sound teeth and incipient non-cavitated carious lesions on permanent teeth of high caries risk patients in order to prevent the onset of caries and its progression. According to the American Dental Association Guidelines for the use of pit and fissure sealants, ICDAS II codes 0, 1 and 2 are recommended for sealant application. A variety of dental materials have been used as sealants using different application techniques. Their effectiveness depends on the formation of a complete seal and is increased by correct technique and moisture control, appropriate follow-up and resealing as necessary. Resin-based conventional sealants are preferred choice, however use of phosphoric acid demineralizes the enamel layer and have elongated treatment time and is more technique sensitive3.
A new bioactive hybrid material (giomer) that combined the advantages of resin composites with glass ionomer cements has been introduced, it based on pre-reacted glass ionomer (PRG) filler technology in which fluoroaluminosilicate glass particles that have previously reacted with the polyacrylic acid were dispersed in resin. Giomer based pit and fissure sealant using self-etch primer eliminates phosphoric acid etch and rinse, thus conserving the enamel and reducing chair side time. However, retention of self-etch adhesive as compared to conventional sealants is questionable4.
A new method for sealant application using air- abrasive technology is less technique sensitive and allows for further cleaning of the grooves prior to sealant placement. The abrasive particles used in air abrasion effectively remove organic plug material from the grooves and allow for deeper penetration of the sealant material into the grooves5.
Aim of the study:
The aim of study is to evaluate retention rate and caries prevention of giomer based sealant with and without pre-treatment by bioactive glass air abrasion in young adults over one year

结局指标
主要结局
Loss of sealant's retention
时间窗: 6 months
Simonsen's criteria Full retention (FR) The material was fully present on the occlusal surfaces Partially lost (PL) The material was present, but as a result of either wear or loss of the material, part of a previously sealed pit or fissure, or both, was exposed \- Totally lost (TL) No trace of the material was detected on the surface.
次要结局
- Secondary Caries(6 months)
