The use of caries preventive approaches, such as community water fluoridation, topical fluoride therapy, plaque control, and dietary sugar control, has been generally seen to be the cause of the overall decline of caries prevalence, which in turn has had a greater effect on smooth surface carious lesion reduction.

A systematic review that included six studies reported that sealing was associated with at least a 10-fold decrease in bacterial counts. GI sealant can also be useful in deeply fissured, primary molars that are difficult to isolate due to a childs pre-cooperative behavior [20]. Sofan E., Sofan A., Palaia G., Tenore G., Romeo U., Migliau G. Classification review of dental adhesive systems: From the IV generation to the universal type. About 31% of children, aged 68 years old, 49% of children, aged 911, and 43% of adolescents, aged 1219, had at least one sealed permanent tooth [2,3,6] (Table 1). A possible reason behind the caries preventive effect of of GIC, despite it not being as retentive as RBS, is that GI remains in the deepest areas of the fissures, even though it is not clinically evident [44]. Chadwick B.L., Treasure E.T., Playle R.A. A randomised controlled trial to determine the effectiveness of glass ionomer sealants in pre-school children. Received 2017 Oct 19; Accepted 2017 Dec 6. A 48-month randomized controlled trial of caries prevention effect of a one-time application of glass ionomer sealant versus resin sealant. Its resin component has improved its physical characteristics, compared to conventional GI [22]. PMC legacy view Sealant retention should also be checked using the explorer in attempt to remove the sealant. If the sealant is dislodged, the fissures should be re-checked for any remaining food debris that may have caused the debonding of the sealant material. Griffin S.O., Gray S.K., Malvitz D.M., Gooch B.F. Caries risk in formerly sealed teeth. Pit and fissure sealants for preventing dental decay in permanent teeth. The addition of filler particles to fissure sealant material seems to have only a small effect on clinical outcomes. Accessibility This paper reviews the literature and discusses the latest updates on the use of pit and fissure sealants. In other words, teeth with partial or complete sealant loss are not at a higher risk of developing caries compared to never-sealed teeth, and the relative risk (RR) ranged between 0.693 and 1.083 [95]. 1 NHANES: national health and nutrition examination survey. Dental caries is a multifactorial disease caused by alteration in the composition of the bacterial biofilm, leading to an imbalance between the demineralization and remineralization processes and manifested by the formation of caries lesions in primary and permanent dentitions [1]. The site is secure. After three years of follow-up, 17.5% of the fluoride varnish group and 19.6% of the fissure sealant group developed caries in their dentin. Since then, the retention rate has become the true determinant and a valid surrogate endpoint for sealant effectiveness in preventing caries [24,46]. Dentists should think about how to protect such teeth from getting carious and whether to seal at an early or late stage of eruption. Arrest of non-cavitated dentinal occlusal caries by sealing pits and fissures: A 36-month, randomised controlled clinical trial. Once the protective role of pit and fissure sealants was established in the 1980s, this type of study design became unethical. 3,179,623 A. Buonocore M.

Muller-Bolla M., Lupi-Pgurier L., Tardieu C., Velly A.M., Antomarchi C. Retention of resin-based pit and fissure sealants: A systematic review. Four of them sealed non-cavitated lesions and the other two used sealant over restorations. A recent update of a Cochrane review concluded that there is only a low quality of evidence that pit and fissure sealants have a superior outcome, when compared to fluoride varnish application, in the prevention of occlusal caries. Ahovuo-Saloranta A., Forss H., Hiiri A., Nordblad A., Makela M. Pit and fissure sealants versus fluoride varnishes for preventing dental decay in the permanent teeth of children and adolescents. Trends in oral health status: United States, 19881994 and 19992004. Nevertheless,in a recent update, the American Dental Association recommendations, in collaboration with the American Academy of Pediatric Dentistry, could not draw any conclusion as to which of the two sealant materials was better due to the very low quality of the evidence available. Feigal and Quelhas in 2003, for example, reported similar retention rates of 61% at 24 months. The aim of this paper was to review the literature regarding the latest updates on the use of pit and fissure sealants on primary and permanent molars in children and adolescents. De Amorim R.G., Leal S.C., Frencken J.E. Maintenance is essential and the reapplication of sealants, when required, is important to maximize the effectiveness of the treatment. Moreover, the shorter etching time decreases the chance of saliva contamination, particularly in pre-cooperative children. The https:// ensures that you are connecting to the Newly erupted permanent first molars should also be seen as susceptible teeth, prior to full eruption. De Assuncao I.V., da Costa Gde F., Borges B.C. Frencken J.E. The filled sealants usually require occlusal adjustments, which lengthen the procedure unnecessarily. Pit-and-fissure sealants were found to be retained on primary molars at a rate of 74 to 96.3% at one year and 70.676.5% at 2.8 years [58]. In Europe, sealant prevalence in adolescents was found to be about 58.8% in Portugal and 8% in Greece [9,10]. Sealants are classified into three sealant materials (Figure 1). Nuva-Seal (LD. It is therefore recommended that, to be more cost-effective, sealants be used only in children at a caries risk of develping caries [32]. Data from NHANES in 20112012, when compared to that from a previous survey in 19992004, showed an increase in the use of sealants in permanent teeth. Both types of sealants had no significant difference in their retention rates; however, the marginal staining was significantly higher for RBS. Nunn J., Murray J., Smallridge J. British Society of Paediatric Dentistry. Oulis C.J., Berdouses E.D., Mamai-Homata E., Polychronopoulou A. In other words, it was no longer acceptable to leave teeth with no sealant as a control after the efficiency of sealant in preventing caries had been proven. The anti-caries effect is also related to the fluoride release property of the cement [45]. Complete retention was 53.57% for filled RBS and 64.39% for unfilled RBS, but the difference was not statistically significant.

Retention of resin-based filled and unfilled pit and fissure sealants: A comparative clinical study. Evidence-based clinical practice guideline for the use of pit-and-fissure sealants: A report of the American Dental Association and the American Academy of Pediatric Dentistry. GI sealants can be classified into low viscosity and high viscosity types. evaluated the fissure sealant retention rate with or without the use of an adhesive system and also compared the retention rate of sealants when using etch-and-rinse adhesive systems (fourth or fifth generations) versus the rate achieved when self-etching adhesive systems (sixth or seventh generations) were used. When there was no radiographic evidence of caries extending to dentin, only 38.2% of the dentists claimed that they would seal the tooths occlusal surface, and 23% chose the option of opening the fissure [91]. They reported a significantly greater retention on fluoridated teeth when LRBS was used and no significant difference in retention when ARBS was used. An evidence-based 2008 report from the American Dental Association and the American Academy of Pediatric Dentistry supports the use of adhesive systems before sealant application for better sealant retention [32,58].

American Academy of Pediatric Dentistry Guideline on Restorative Dentistry. The use of moisture control systems, such as the Isolite system (Innerlite Incorporation, Santa Barbara, CA, USA) provides less time for the procedure and offers comparable sealant retention rates to cotton roll isolation or the use of a rubber dam [60]. One more study also evaluated sealant retention when treating the enamel with a topical fluoride gel before acid etching clinically and in-vitro. Pit and fissure sealant is an effective means of preventing pit and fissure caries in primary and permanent teeth. Rock W.P., Potts A.J., Marchment M.D., Clayton-Smith A.J., Galuszka M.A. Surveillance for dental caries, dental sealants, tooth retention, edentulism, and enamel fluorosis United States, 19881994 and 19992002. It bonds chemically to enamel and dentin through an acid-base reaction between an aqueous-based polyacrylic acid solution and fluoroaluminosilicate glass powder [28]. On the basis of caries risk assessment, primary teeth can be judged to be at risk due to fissure anatomy or patient caries risk factors, and would therefore benefit from sealant application [55]. Most of the manufacturers instructions for the use of fissure sealants recommend careful cleaning of the pits and fissures before acid etching. Previously, when investigating the effectiveness of sealants in preventing caries, half-mouth study designs were used, in which sealed teeth were compared with unsealed teeth as controls. It has been reported in a systematic review that high levels of BPA were found in saliva samples that had been collected immediately or one hour after resin-based sealant placement. It was found that there was no statistically significant difference between the retention rate of the sealant applied after tooth surface treatment with topical fluoride and the control group that did not receive any fluoride treatment prior to the sealant application [56]. It is therefore important to evaluate to what extent other preventive approaches are used, such as professional topical fluoride application, regular daily toothbrushing with fluoridated toothpaste, the use of fluoride supplements, and diet counseling [59,84]. Tellez M., Gray S.L., Gray S., Lim S., Ismail A.I. in 1993 when they used hydrophilic bonding materials to aid the bond strength when the sealant is applied in a moist environment [65]. A polyacid-modified resin-based sealant has a better adhesion property to enamel and dentin and is also less water-soluble, compared to GI sealant material [33], and less technique-sensitive, compared to resin-based sealants.
