“…Additionally, in order to reduce selection bias, trials that seek to assess the caries-preventive effect of fissure sealants should aim to recruit children soon after the eruption of their first molars. Previous publications (2,12,40) have highlighted a number of factors that could potentially affect the cariespreventive effect of fissure sealants. Only some of the trials have reported on these factors.…”

Abstract:The purpose of this quantitative systematic review was to appraise the evidence on the caries-preventive effect of glass ionomer cement (GIC) in relation to resin-based fissure sealants. Nine English and two Portuguese databases were searched (15 January 2008). Randomized clinical trials and systematic reviews were considered for inclusion. Trial exclusion criteria were: drop-out rates > 33%; no randomization; baseline differences in groups not statistically adjusted; and no clinically important outcomes were presented. Two authors reviewed the articles independently. The outcome measure for the caries preventive effect was caries absence on sealed teeth. Of the 112 identified articles, 25 were selected for review. Of these, 14 were excluded and 11 accepted (8 trials; 3 systematic reviews). The accepted reviews provided no evidence of superiority of either sealant material. Six trials were included for meta-analysis. The pooled odds ratio was 0.96, 95% CI 0.62-1.49, indicating no difference in the caries-preventive effect of GIC and resin-based fissure sealant material. This systematic review with meta-analysis found no evidence that either material was superior to the other in the prevention of dental caries. Thus, both materials appear equally suitable for clinical application as a fissure sealant material. (J Oral Sci 51, 373-382, 2009)

“…An alternative to allow a more efficient biofilm control in this area is the use of dental sealants. 43 The sealing of occlusal surfaces in a preventive approach has shown positive results (caries risk reduction of 33-65%); [44][45][46][47][48] however, it will depend on a series of variables. Ahovuo-Saloranta et al, 48 through a systematic review of the literature, showed that the effectiveness of sealants is obvious for high caries-risk individuals, but information on the benefits of sealing to patients with different caries-risk levels is lacking.…”

The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene), among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene) should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

“…A systematic review published in the early 1990s found that the preventive fraction (PF), that is the proportion of occlusal decay prevented, among children receiving a one-time application of autopolymerizing sealant was 71%. 5 This preventive fraction PF is given by (I 0 -I 1 )/ I 0 where I 1 is the incidence of dental caries in the group treated with fissure sealants and I 0 is the incidence in the control group. Ultra-violet light polymerized sealant had a PF of 46%, but this 'first generation' product is no longer available.…”
