Evaluation of shear bond strength of silorane resin to conventional, resin-modified glass ionomers and nano-ionomer cements.

Aim: To evaluate the shear bond strength of silorane composite resin to conventional and resin-modified glass ionomer cements.

Materials And Methods: Shear bond strengths of Vitrebond (Group I), Ketac N100 (Group II) and Ketac Bond (Group III) glass ionomer cements to the composite Filtek P90 were evaluated. The bond strength was tested using a universal testing machine at a cross-head speed of 0.

The effect of various surface contaminants on the microleakage of two different generation bonding agents: A stereomicroscopic study.

Aim: The aim of this in vitro study was to evaluate the microleakage of two different generation bonding agents in the presence of various surface contaminants.

Materials And Methods: Class V cavities were prepared on 150 extracted human permanent molars. The samples were randomly divided into two main groups of 75 teeth each.

Dental ceramics: An update.

In the last few decades, there have been tremendous advances in the mechanical properties and methods of fabrication of ceramic materials. While porcelain-based materials are still a major component of the market, there have been moves to replace metal ceramics systems with all ceramic systems. Advances in bonding techniques have increased the range and scope for use of ceramics in dentistry.

Endo-perio lesions: diagnosis and clinical considerations.

The interrelationship between periodontal and endodontic disease has aroused confusion, queries and controversy. Differentiating between periodontal and endodontic problems can be difficult. A symptomatic tooth may have pain of periodontal and/or pulpal origin.

Nonsurgical management of endodontic mishaps in a case of radix entomolaris.

Anatomic variations can significantly contribute to the incidence of endodontic mishaps. Perforations and separated instruments form the bulk of such mishaps. Furcal perforations are undesired complications of endodontic treatment, which result in the loss of integrity of the root and further destruction of the adjacent periodontal tissues.

Is it the end of the road for dental amalgam? A critical review.

The longevity of dental restorations is dependent on many factors, including those related to materials, the dentist, and the patient. Dental amalgams have successfully served the profession for over a century. The main reasons for restoration failure are secondary caries, fracture of the bulk of the restoration or of the tooth, and marginal deficiencies and wear.
