Comparison of the effectiveness of fissure sealants in Finland, Sweden, and Greece

Abstract

The sealing of all molar fissures proved to be no more effective than sealing risk fissures of subjects. Early sealing did not result in any better outcome than late sealing. The effectiveness of sealant treatment in preventing dental restorations is dependent on the caries risk of individuals and caries prevalence of the country.

Clinical comparison of Fuji VII and a resin sealant in children at high and low risk of caries

“…But this does not mean that sealing strategies are unnecessary in HR children. Recently published systematic reviews recommend fissure sealing in children at high risk of caries 39) , and sealants have been shown to be more cost effective if used in patients with a high rather than low caries risk 18,19) . These results indicate a need for comprehensive health promotion work to reduce overall caries activity in HR adolescents, including shorter recall intervals, professional tooth cleaning, changing children's carbohydrate intake and oral hygiene habits, resealing in cases of sealant loss and combined use of topical fluoride 20,34) For molars sealed with Fuji VII, the rates of development of caries LR and HR subjects were 6.3% and 11.1% respectively and there was no significant difference.…”

“…The results of studies assessing the effectiveness of fissure sealant according to patients' caries risk status have been contradictory 17,18) . Some studies have shown that fissure sealants are more effective if used in HR rather than low risk (LR) children 18,19) ; others have found that the higher the dft, the higher the risk of fissure sealant failure 20) , though such sealants are effective in individuals with low or moderate carious activity 21) . There has been no study discussing the preventive effect of Fuji VII in children of different caries risk status.…”

Retention and caries-preventive effect of glass ionomer and resin-based sealants: An 18-month-randomized clinical trial

“…This outcome is in agreement with the findings of earlier investigations where baseline caries experience was associated with caries development 22,33,43) . It has been reported that the great variability in the reduction of caries is related to the prevalence of caries in the individuals and populations 44) . Our study was conducted among children from a high risk population which may explain the obtained results.…”

Classical and Modern Methods in Caries Epidemiology

“…All these studies used the nonparametric Kaplan-Meier method or Bayesian analysis for comparing the tooth-specific survival data. The non-parametric methods have been used for the determination of the survival time of each tooth remaining caries-free, either from the tooth emergence Larmas, 1995, Suni et al, 1998) or from the birth of the subject up to 20 years of age (Leskinen et al, 2008a). The results show that onset of caries occurs immediately after tooth emergence in first and second molars, equally on left and right sides (probably indicating that caries commits these two molar teeth at the same time on the left and right sides), but caries onsets on maxillary and mandibular molars differ (significantly), mandibular molars being more caries prone.…”
