Effect of composite/amalgam thickness on fracture resistance of maxillary premolar teeth, restored with combined amalgam-composite restorations
BACKGROUND Combined amalgam-composite restorations have been used through many years to benefit from the advantages of both dental amalgam and composite resin. Two variations have been mentioned for this technique, this study investigated the fracture resistance of maxillary premolar teeth with extended mesio-occluso-distal (MOD) cavities, restored with the two variations of combined amalgam-co...
متن کاملComparison of the Effect of Three methods of Porcelain Surface Treatment on Shear Bond Strength of Composite to Porcelain
Background and Aim: Several methods are available for intraoral repair of chipped porcelain restorations by composite resin. Also, there is still controversy regarding the best method of porcelain repair in terms of bond strength and cost effectiveness. This study aimed to compare three methods of porcelain surface treatment on shear bond strength (SBS) of composite to porcelain. Materials a...
متن کاملEffect of Alkaline Vs Acid Surface Treatment on Bond Strength of Adhesives Used for Amalgam Repair
Objective: To assess the effect of alkaline versus acid surface treatment on bond strength of adhesives used for amalgam repair. Materials and Method: Sixty cylindrical samples were prepared by condensing amalgam into plastic tubes of 4mm diameter and 10mm length. Tubes were filled up to 5.0mm with admixed amalgam. They were allowed to set hard for three months. The samples were divided into A1...

متن کاملEvaluation of Shears Strength of Dowel Amalgam and Post-amalgam in Root Canal-treated Teeth
Introduction: Amalgam, which can be applied with or without dowel, is one of the commonly used restorative materials for core restoration in pulpless teeth. The current study aimed to compare the shear strength of amalgam cores with and without dowel. Methods: A total number of 20 recently extracted mandibular premolars were assigned to two groups of 10 equal s...
متن کاملBrittle fracture of dental amalgam.
The brittleness of dental amalgam limits its use to sites in which tensile stresses can be kept at a minimum. If the cause for the brittleness could be ascertained, then an approach to correct this problem could be devised. Physical properties of metals are ultimately manifested in, and can be explained by, their microstructure. Through the work of several researchers,1-3 means of identifying t...
