BACKGROUND The long-term capability of resin sealants and glass ionomer cements to release fluoride is associated to a reduction in pit and fissure caries. The regular use of fluoride varnishes/toothpastes can result in the absorption of fluoride into the sealant. The objective of the present study was to assess the fluoride release/uptake capacities of different fissure sealants. MATERIAL AN...

PURPOSE The purpose of this study was to formulate and characterize experimental antibacterial fluoride-releasing sealants and compare them with commercial sealants for fluoride release, recharge, adhesion, and microleakage. METHODS Two experimental sealants (Exp-1, Exp-2) containing a synthesized antibacterial fluoride-releasing monomer and fluoride-releasing filler were formulated. Exp-2 al...

Nowadays there are various kinds of insulating glass available on the global market. The most popular type is the double sealed insulating glass unit (IGU). Polysulfide, polyurethane and silicone based sealants are the premium elastic sealants used as secondary seal. Provided they are formulated to the state-of-art these sealants meet all requirements on manufacture and service properties of we...

Dental caries is an oral disease, which has a high worldwide prevalence despite the availability of various prophylactic means, including the daily use of fluoride toothpastes, water fluoridation, dental sealants, oral health educational programs and various antiseptic mouth-rinses. One important reason for this is uncontrolled increase in consumption of foods containing considerable sucrose co...

Few studies have specifically compared the prevalence of dental caries among contemporary Australian Aboriginal and non-Aboriginal children. Historically, Aboriginal groups have had substantially fewer dental caries than non-Aboriginal peoples. More recently, however, this trend appears to have been reversed, with improvements in the oral health of non-Aboriginal children and a deterioration in...

The objectives were to demonstrate that a combination of preventive regimens could significantly reduce dental disease in a school population, to demonstrate the feasibility of a school-based program in relation to sustained benefits. There were 1286 students in 1st and 6th grades enrolled in the study. Subjects were stratified by grade, sex, and race and randomly placed in a treatment or educa...

OBJECTIVES This study investigated socio-economic factors associated with the placement of fissure sealants in a population of South African adolescents. METHOD The study participants were high school students aged 12 to layers who provided baseline data during 2005 in a tobacco-use prevention trial, and consented to oral examination (n=1103). Information was obtained using a self-administere...

BACKGROUND Surface sealants have been successfully used in the prevention of erosive tooth wear. However, when multiple tooth surfaces should be sealed, the light-curing procedure is very time-consuming. Therefore, the aim of this study was to investigate whether reduced light-curing time (while maintaining similar energy density) has an influence on resin-based surface sealant cytotoxicity. ...

The resins used in sealants are Bis-GMA and urethane dimethacrylate diluted with appropriate dimethacrylate resins. 8,9 Recently, inorganic fillers have been added to sealants to allow the materials to be both esthetically pleasing and more visible clinically. 1°,11 As a result, the issue of proper polymer tag formation that is essential for sealant retention becomes important,a, 1113 Although ...
