The current study was aimed towards evaluating retention of the sealants on the first permanent molars of low socioeconomic class children 5 years post application. Also presence and absence of dental caries was determined. It is a follow up study to evaluate the retention of sealants placed during a randomized control trial conducted in children of low socioeconomic class school of Karachi in ...

PURPOSE The objectives of this study were to investigate the fluoride levels in plaque and saliva before and after applying fluoride-containing pit and fissure sealants, and compare the fluoride release of 2 types of sealants at the different time intervals. METHODS Eighteen children ages 6 to 9 years were randomly divided into 2 groups: Group 1--sealant containing fluorosilicate glass (Helio...

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...

Dental adhesive systems used for bonding dental resins to enamel and dentin have evolved through several “generations,” with changes in chemistry, mechanism, number of bottles, application technique, and clinical effectiveness. The trend in the latest generation of dental bonding systems is to reduce the number of components and clinical placement steps. The introduction of i bond, a single-bot...

PURPOSE The purposes of this study were to: (1) evaluate the ability of a laser fluorescence (LF) unit to detect simulated caries under pit and fissure sealants; (2) determine the effect of an opacifying agent in sealants on LF values; and (3) determine interexaminer reproducibility values of the unit in a highly controlled, laboratory setting. Sealant characteristics specifically considered we...

Sealing occlusal pits and fissures in teeth is a common and highly effective preventive method. The main purpose of sealing the pits and fissures is to prevent plaque microflora and food debris accumulation in the fissures where saliva cannot reach and clean the debris, re-mineralise initial lesions, and buffer the acid produced by cariogenic bacteria. Resin-based sealants, as well as glass ion...

The penetration coefficients (PC) and tensile bond strengths of two pit and fissure sealants and a low viscosity bonding resin were evaluated. The penetration coeftYcients of the resin systems were determined at 22°C. Five determinations were done with each resin. Bonded test specimens were loaded to failure in the tensile mode in an Instron testing macl~’ne. Ten specimens were prepared with ea...

Arresting occlusal enamel caries lesions with pit and fissure sealants The aim of this study was to evaluate the feasibility of pit and fissure sealants and the effectiveness of the two sealant methods applied in every-day practice in public dental health care in Finland. Two sealant methods were evaluated according to their effectiveness in preventing dentin caries at occlusal surfaces and sea...
