Centenary year of scientific papers in the British Dental Journal.

This final part of the centenary series covers Kramer and McLean's paper, 'The response of the human pulp to self-polymerising acrylic restorations', which was one of the first papers to give such a detailed account and assessment of such changes. It is reviewed by Dr Graham Mount, who first met John McLean in 1973 and has worked closely with him since then.

Evolução dos sistemas adesivos / Evolution of bonding systems

No breve histórico sobre adesivos dentinários, nos considerados de 1ª e 2ª gerações, não se promovem nenhum pré-tratamento de dentina, possuindo propriedades hidrofóbicas formando uma ligação fraca entre o dente e o material restaurador. Já os de 3ª, 4ª e 5ª gerações, considerados hidrofílicos, permitem uma ligação mais efetiva do material com as estruturas duras do dente

Dentinal bonding agents versus glass-ionomer cements.

The long-term bonding of dental material to dentin remains an area of great controversy and the results of in vitro testing do not always reflect those found in vivo. The clinician is faced with a large number of dentinal bonding agents that have had limited testing in vivo and are frequently replaced before any long-term clinical testing has been completed. Glass-ionomer cements, although having a longer history of good adhesion to dentin, are not suitable for use in high-stress-bearing areas. The selection of materials for specific clinical situations has become more and more difficult. This paper gave a personal view of the history and evolution of both resin bonding agents and glass-ionomer cements and their potential in clinical use.

Dentin bonding system. Part I: Literature review.

Currently, clinicians face choices of restoration including amalgams (mercury-based, gallium-based alloys, or mercury-free silver-based substitutes), composite resins, ceramics, and gold alloy. In order to choose an appropriate restorative material, many parameters are involved; they include preparation time requirements, finishing and polishing, marginal integrity, anatomy and contours, chipping and fracture, sensitivity, microleakage, wear resistance, and corrosion resistance. It is generally believed that amalgams are still evaluated as the best of all restorative materials as far as the aforementioned parameters are concerned. It is claimed that the amalgams exhibit in the range of 10 to 25 service years, while the composite resin exhibits ranging between 7 and 11 service years. When a composite resin requires a mass large enough for indirect fabrication, a bonding system is demanded with which this restoration should form an instantaneous, impervious, and stable bond to the tooth structure. Roughly a quarter century has passed since the research and development of a promising dentin bonding system was initiated. We are now in the fifth generation of the dentin bonding system, during the research and development of which various types of bonding agents as well as bonding models have been introduced. In this article, the history of development of the bonding agents and the understanding of the bonding mechanism will be reviewed.

Bonding to enamel and dentin: a brief history and state of the art, 1995.

The acid-etch technique for bonding composite resins to enamel has revolutionized the practice of restorative dentistry. The ability of clinicians to bond restorative materials to enamel has fundamentally changed such diverse areas as cavity preparation, caries prevention, and esthetic treatment options. Although bonding of resin to dentin has proved to be a difficult challenge, ongoing advances are improving the reliability and predictability of dentinal adhesion. The purpose of this article is to provide a brief history of enamel and dentinal bonding, as well as an overview of the current state of the art.

[Scotchbond from 1983 to 1992. The history of a market setter reflected in the literature. A review of the literature]. / Scotchbond von 1983 bis 1992: Die Geschichte eines Marktrenners im Spiegel der Literatur. Eine Literaturübersicht.

In this critical literature review 140 [correction of 136] publications dealing with Scotchbond were chronologically compiled since 1983 when Scotchbond was introduced to the dental market. The publications dealing with dentinal bonding were analyzed. Critical statements were predominant in the in-vivo- as well as in the in-vitro-studies. The literature reviewed for a period of ten years clearly demonstrated that the expectations created by the manufacturer and some initial studies concerning dentinal bonding did not become true. Long before private practitioners realized that Scotchbond didn't live up to the standards promised by the manufacturer, independent scientists had doubted the efficiency of the product. The conflict between market orientated and objective information for the private practitioners becomes obvious in this literature review.
