dental materials that are used in dentistry should be harmless to oral tissues, so they should not contain any leachable toxic and diffusible substances that can cause some side effects. reports about probable biologic hazards, in relation to dental resins, have increased interest to this topic in dentists. the present paper reviews the articles published about biocompatibility of resin-restora...

The clinical effectiveness of Delton (Johnson and Johnson Dental Products Company, East Windsor, New Jersey) fissure sealent was studied in 205 children 6 to 10 years of age (mean age, ;n/2). A total of 993 children in Grades 1, 3, and 4 was screened, and subjects were selected if there was evidence of previous dental caries in the mouth and if a pair of contralateral maxillary or mandibular fi...

We examined the light transmittance characteristics and refractive indices of light-activated pit and fissure sealants. Five commercial pit and fissure sealants and human enamel were studied, along with the CIE L*a*b* color values of the materials and enamel. The light transmittance spectra of the pit and fissure sealants showed a similar trend to the enamel, especially at wavelengths below 530...

AIM Dental caries in pits and fissures of molars is still very common in young people, despite a gradual reduction in their incidence and prevalence. Prevention with the aid of dental fissure sealants can help to reduce the onset of decay. In vitro tests were conducted to compare the bond strength to enamel of self-etching sealants versus those applied using the conventional procedure. METHOD...

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...

PURPOSE To assess the knowledge, attitude and utilisation regarding fissure sealants (FS) and preventive resin restorations (PRR) among Malaysian dentists. MATERIALS AND METHODS A questionnaire consisting of 35 questions was distributed by mail or an online survey to 425 registered dentists selected according to place of work by stratified random sampling. RESULTS One hundred fifty-three de...

This study evaluated the effects of three modes of education on dentists' knowledge, attitudes, and use of pit and fissure sealants. A randomly selected group of dentists was invited to participate in a sealant education initiative. During a 12-month period, a total of 662 dentists either (1) attended continuing education courses, (2) received written materials and videotapes by mail, or (3) re...
