BACKGROUND Dental caries among children is one of the greatest challenges faced by dentists globally; especially that of susceptible surfaces like the Pit and fissures. Dental sealants have proved to be an effective way to prevent caries development. The Clinical success of any material depends upon its adhesion to tooth structure, resistance to wear and ability to withstand the masticatory or ...

PURPOSE The aim of this study was to determine if flowable composites can be used as pit and fissure sealants without bonding agents. METHODS Three flowable composites (Filtek Flow, Tetric Flow, Charmfil Flow) and a filled sealant (Ultraseal XT Plus) were used. The patterns of resin tag formation in the 4 sealant materials were compared using scanning electron microscopy. For the microleakage...

OBJECTIVES The objective of this one-year clinical study was to investigate the effect of two adhesive systems (Adper Single Bond, a two-step etch-and-rinse and Clearfil SE Bond, a two-step self-etch system) on pit-and-fissure sealant retention in newly-erupted teeth. This study compared the success of the sealants in mesial and distopalatal grooves with and without these two adhesive systems. ...

BACKGROUND The incorporation of fluoride into sealants has been viewed as a viable way to prevent pit-and-fissure caries by potential inhibition of demineralization through the release of fluoride to enamel. The authors conducted a study to examine the effect of a recently introduced fluoride-releasing sealant (ProSeal, Reliance Orthodontic Products, Itasca, Ill.) on enamel demineralization in ...

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...

The effect of sealant placement and sealant loss on caries-like lesion formation was studied using an artificial caries technique and polarized light microscopy. The results indicate that lesion formation does not occur subjacent to an intact sealant. Even enamel which had lost is sealant was found to be caries-free. It is concluded that resin tags may be responsible for the ability of sealants...

The aim of this study was to compare the shear bond strengths (SBS), failure modes (adhesive, cohesive, or mixed), and marginal microleakage occurrence of conventional resin (CR)-based, glass ionomer (GI)-based, and self-adhesive resin (SAR)-based fissure sealants with or without prior phosphoric acid (PA) etching. Fifty extracted premolars were randomly and equally assigned into five groups -G...

Four different commercially available sealants were placed in caries-free permanent premolars and molars for a total of 381 teeth in 53 young participants. The volumetric loss of sealant material was evaluated over a two-year period using a tooth replica technique previously published. The pattern of progressive sealant loss was similar for all materials and for molars and premolars. Approximat...

Oral diseases are progressive, cumulative, and become more intricate to treat with advancement. While dental caries is an infectious transmissible disease with children being at the highest risk, primary prevention can reduce this risk. Primary prevention in dentistry is usually considered to be community fluoridated water supplies, professional fluoride treatments, and pit and fissure sealants...

A survey was conducted to identify and compare sealant knowledge and sources of sealant information of parents whose children had and had not received fissure sealants. The socioeconomic characteristics of these individuals were also compared. The sealant group was composed of the parents of children found to have a sealant on at least one permanent tooth during dental examinations of 2,036 ele...
