“…But the success of the sealant for caries prevention depends on long-term retention. [7][8][9] The study done by Janet C Hitt, 10 investigated bond strength in vitro, when bonding agent was used beneath sealants under varied conditions of contamination. Bonding agent used without contamination yielded bond strengths significantly greater than the bond strength obtained when using sealant alone without contamination.…”

Aim:The aim of the study is to evaluate the retention of fissure sealants following the use of self-etch priming agent and traditional acid-etch method. Materials and methods:Thirty subjects around the age 8 to 12 years old school children was recruited to this study by two dental professionals. Paired lower molars were the principal unit of analysis. Pit and fissure sealant placement lower molars followed by traditional acid-etching done on 36 and self-etch primer (3M ESPE) on 46. After 6 months the retention was evaluated using Smales RJ and Wong KC (1999) retention evaluation criteria. The Chi-square test was used to evaluate the difference in the retention rates. Results:The total retention in the self-etch sealant group seems to be high, the difference between the groups was not statistically significant. The chi-square computed value was found to be c 2 = 0.417, df = 1 and p = 0.519. This means that there was no significance difference between the retention rate of self-etch sealant compared to conventional acid-etch technique. Hence, this study conclude that self-etch primer (3M ESPE Adper) is effective in bonding sealant to enamel and that the simplified method dramatically shortens treatment time and treatment complexity.

“…Fluoride is incorporated into resins by two waysthe first utilizes a soluble fluoride salt which, after application, dissolves releasing fluoride ions,which may compromise the integrity of the resin [18] .This method has been questioned, because fluoride release resulting from the dissolution of a soluble salt might weaken the sealant and thereby might reduce its usefulness as a preventive agent [19]. The other system uses an organic fluoride that is subsequently released by an exchange with other ions in the system [20].…”

Aim-to review about the colour changing and fluoride releasing pit and fissure sealants. Background-dental caries is the most important and the most common intra oral disease that is seen both in children and adults. This being the era of preventive dentistry, the main aim of the dentist is to prevent the teeth from any carious involvement. Earlier,two main methods prophylactic restoration and prophylactic odontotomy were used in the management of pit and fissure caries.it is even possible to establish a caries free dentition in childhood with the increasing advancements in pit and fissure sealants. This article mainly aims to review the recent advancements in pit and fissure sealants like color changing sealants,fluoride releasing sealants and resin based sealants. Reason-to understand more about the colour changing and fluoride releasing pit and fissure sealants. …………………………………………………………………………………………………….... Introduction:-Dental sealants are preventive dental treatment where pit and fissure of primary or permanent molar and premolar are filled with material thereby preventing caries [1]. Aim of pit and fissure sealant is to prevent developing caries which is achieved by blocking the surface and prevents bacteria from getting attached to it [2]. Deep pits and fissures favor food retention and are difficult to clean by routine brushing. It provides a favorable environment for the oral microorganisms to thrive and convert the carbohydrates to acids, leading to demineralization of the enamel. [3] Previously, during the early 1920s two main procedures were done for the management of pit and fissure caries, they are prophylactic restoration and prophylactic odontotomy. Which was later followed by Kline and Knutson who discovered treatment of pit and fissure caries with ammoniacal silver nitrate and Bowen RL et al who discovered Bis-GMA ( Bisphenol A -Glycidyl Methacrylate) a resin sealant material. Thus, resin sealant methods were born [4].Sealants are the most effective clinical technique to prevent pit and fissure caries.The cost effectiveness of sealants,naturally, is based upon sealant retention. While the rates of sealant retention on occlusal surfaces are relatively high at five years, [5][6][7][8] sealant retention for buccal and lingual pits and fissures of molars is considerably lower [9].A recent ,significant development with resin based sealants is the development of moisture-tolerant chemistry.In the past,isolation and exclusion of moisture with resin-based sealantswasrequired.A moisture tolerant,resin-based sealant does not require an additional bonding agent [10][11][12].

“…While autopolymerizing sealants have been observed for as long as 15 years, newer materials have only been subject to short-term follow-up. Since the highest rate of sealant loss occurs during the first year after application, 6 the calculation of annualized loss rates can mean that sealants observed for short periods of time can appear to be less effective. Nevertheless, currently available evidence indicates the following: 7 • Autopolymerizing sealants have high longterm retention rates, with 60% of surfaces remaining covered after 5 to 7 years.…”
