Abstract
The objective of the present study provides further data comparing retention, marginal integrity and caries preventive effects of two fissure sealants (glass ionomer based; GC Fuji VII Capsule [Fuji VII] and ormocer based; Admira Seal [AS]) in children. This study was designed as a randomized single-blind clinical trial. The permanent first molars (PFMs) of 50 children, 7-13 years of age (mean age: 8.9 +/- 1.3 years), were sealed with a split-mouth design. Fissure sealants applied to the PFMs according to the manufacturer's recommendations by one pediatric dentist. Clinical evaluation of the sealants was carried out to record retention, marginal integrity and presence of caries at 6, 12, 18 and 24 months after placement by the other pediatric dentist. Kaplan-Meier survival analysis and Cox's regression models were used to estimate the probability of two sealants success. Alpha and Bravo retention rates at the end of follow-up were 13% and 80% for Fuji VII and 3% and 83% for AS, respectively. For retention and marginal integrity between fissure sealants was found similar survival rates (p > 0.05). After 24 months, presence of caries was 16% for Fuji VII and 32% for AS (p < 0.05). Fuji VII and AS exhibited similar retention and marginal integrity during 24 months. However Fuji VII was showed better results than AS for caries preventive effect. Consequently, Fuji VII sealants may be a better choice for preventing occlusal caries.

A Two-Year Clinical Evaluation of Glass Ionomer and Ormocer Based Fissure Sealants
268 The Journal of Clinical Pediatric Dentistry Volume 37, Number 3/2013
    • "Next, we excluded 426 articles, which we had assessed by means of full-text screenings, and we included 24 articles, 1,19-41 which represented 23 studies, in this review (Figure 1). 19,21,23,25,27,29,30,32,[34][35][36][37]40 Table 2summarizes the characteristics of the included populations, which investigators described as including children and adolescents aged 3 to 16 years who were living in settings with and without water fluoridation. We did not identify any studies that met the selection criteria whose investigators had provided information about the effect of sealants in an adult population. "
    [Show abstract] [Hide abstract] ABSTRACT: National Health and Nutrition Examination Survey 2011-2012 data indicated that, in the United States, nearly one-fourth of children and over one-half of adolescents experienced dental caries in their permanent teeth. The purpose of this review was to summarize the available clinical evidence regarding the effect of dental sealants for the prevention and management of pit-and-fissure occlusal carious lesions in primary and permanent molars, compared with a control without sealants, with fluoride varnishes, or with other head-to head comparisons.

    • "A Medline search via Pubmed using the Clinical Query option identified six clinical trials that evaluated the caries preventive effect of different dental sealing materials and were published after the date of the end of the search performed in the Cochrane review. These studies tested and compared the caries preventive effect of high-viscosity glassionomer cements, fluoride-releasing resin-based sealants, a flowable composite resin, glass carbomer sealants and an ormocer sealant212223242526. Most of them had a split-mouth design and only two found that one material performed better than the other; the results of one study favored a highviscosity glass-ionomer sealant over an ormocer sealant and those of another study favored a high-viscosity glass-ionomer cement over a glass carbomer sealant. "
    [Show abstract] [Hide abstract] ABSTRACT: Objectives: (1) To describe caries lesions development and the role of fluoride in controlling disease progression; (2) to evaluate whether the use of fluoride-releasing pit and fissure sealants, bonding orthodontic agents and restorative materials, in comparison to a non-fluoride releasing material, reduces caries incidence in children or adults, and (3) to discuss how the anti-caries properties of these materials have been evaluated in vitro and in situ. Methods: The search was performed on the Cochrane Database of Systematic Reviews and on Medline via Pubmed. Results: Caries is a biofilm-sugar dependent disease and as such it provokes progressive destruction of mineral structure of any dental surface - intact, sealed or restored - where biofilm remains accumulated and is regularly exposed to sugar. The mechanism of action of fluoride released from dental materials on caries is similar to that of fluoride found in dentifrices or other vehicles of fluoride delivery. Fluoride-releasing materials are unable to interfere with the formation of biofilm on dental surfaces adjacent to them or to inhibit acid production by dental biofilms. However, the fluoride released slows down the progression of caries lesions in tooth surfaces adjacent to dental materials. This effect has been clearly shown by in vitro and in situ studies but not in randomized clinical trials. Significance: The anti-caries effect of fluoride releasing materials is still not based on clinical evidence, and, in addition, it can be overwhelmed by fluoride delivered from dentifrices.
