PURPOSE More than five hundred million direct dental restorations are placed each year worldwide. In about 55% of the cases, resin composites or compomers are used, and in 45% amalgam. The longevity of posterior resin restorations is well documented. However, data on resin composites that are placed without enamel/dentin conditioning and resin composites placed with self-etching adhesive system...

Luting materials for fixed prosthesis must fulfill special requirements in order to retain indirect restorations and fully maintain the integrity of abutments. The main requirements (inhibition of plaque accumulation, sealing of interface, possible antibacterial effects, acceptable solubility, wear, mechanical properties, adhesion, radiopacity, film thickness, type of curing, esthetics, storage...

In the described technique, a vinyl polysiloxane material is used as a matrix for the indirect fabrication of multiple custom-cast posts and cores. The matrix technique enables the clinician to fabricate multiple posts and cores in a short period of time. The form, harmony, and common axis of preparation for all cores are well controlled before the definitive crown/fixed partial denture restora...

BACKGROUND: There are several treatment options available to reduce the post-operative sensitivity (POS) of indirect resin composite restorations. AIM: This study was evaluate effect air abrasion on delayed dentin sealing POS for MATERIALS AND METHODS: Twenty-eight patients between ages 18 and 30 were enrolled randomly assigned one two groups, with 14 teeth (n = 14) in each group. Following col...

Coronal rehabilitation of a severely damaged teeth is a challenge for clinician. The Endocrown is indicated for restoration of severely damaged molar, which requires specific restoration technique. This therapy promotes the stability and retention of the indirect restoration, without the need of a cast metal core or reconstruction with intracanal post, thereby reducing the treatment time. The m...

introduction: one of the clinical problems in orthodontics is the bonding of brackets tocomposite restorations. the aim of this study was to evaluate the shear bondstrength of brackets bonded to composite restorations using excite. methods:forty brackets were bonded to composite surfaces, which were embedded inacrylic resin. one of the following four protocols was employed for surfacepreparatio...

Submit Manuscript | http://medcraveonline.com Teeth presenting diastema and misalignment are a common finding in the anterior maxillary dentition, and this fact can strongly affect the appearance of a smile, besides being displeasing for the patients.1 The current literature suggests several approaches for the correction of diastemas and misaligned teeth, such as orthodontic intervention, direc...
