Advanced Science, EarlyView.Atomically correlated phosphorus–sulphur sites are introduced into graphitic carbon nitride to regulate charge distribution, suppress localized trapping, and enhance oxygen activation. The resulting metal‐free photocatalyst selectively promotes the two‐electron oxygen reduction pathway, enabling efficient hydrogen peroxide production in pure water ...

Australian Dental Journal, 1974
AbstractThe adhesive bonding of a fast‐setting system consisting of three different monomers to etched human enamel surfaces was investigated. Combinations of MMA, methacrylic acid, and adducts of glycidyl methacrylate andp‐substituted phenols have been employed. Best results were obtained with hydrogen ort‐butyl‐substituted phenols. It is shown that a

Characteristics of Fissure Sealants
Journal of Dental Research, 1981In this paper the nature and some of the properties of bis-GMA and other related products were characterized using infrared spectroscopy, viscometry, and refractive index studies. Then, using the determined constituents of these products, simulated formulations were prepared.

Caries Research, 1978
This study was carried out to investigate the retention of several fissure sealant materials in occlusal fissures in vitro. 400 sound human teeth were coated with varnish leaving occlusal and smooth surface sites unpainted and exposed for experiment.

Swiss dent, 1990
Compared to the situation in Japan, the USA or Great Britain fissure sealing for caries prevention seems to be less popular in Switzerland. Each Swiss dentist used per year (i.e. statistical average in 1988) sealants for an amount of sfr 40.00 compared to e.g. sfr 50.00 in the USA or sfr 55.00 in Japan.

Thermocycling of Pit and Fissure Sealants
Journal of Dental Research, 1976Two commercial pit and fissure sealants were compared in vitro for thermocyclic failure. Both products failed; however, one was three times more resistant to failure than was the other.

Newly erupted posterior teeth in both the primary and permanent dentitions are vulnerable to dental caries attack due to deep, uncoalesced, and not-so-soundly mineralized pits and fissures as compared to their matured counterparts. Therefore, it is more important to “catch them young” before it becomes too late to save them from the deleterious effects

Modern Thoughts on Fissure Sealants
Dental Update, 2000It has long been known that fissure sealants are an important part of the prevention and control of dental caries in pits and fissures. However, their usage is still sporadic and generally not related to evidence-based guidelines. Caries prevalence has changed since sealants were introduced and this has significant implications for the criteria on ...

The Effectiveness of Pit and Fissure Sealants
Journal of Public Health Dentistry, 1989AbstractThis review addresses two major issues related to the use of pit and fissure sealants. First, the epidemiology of occlusal caries for children and adults is examined to determine if there is a basis for administering sealant programs to different age groups.
