Winner of the Standing Ovation Award for “Best PowerPoint Templates” from Presentations Magazine. Effect of carbamide peroxide and hydrogen peroxide on enamel surface: an in vitro study. Step 1: Material Selection the ability to achieve a good finish and polish on anterior composites is determined by two very important fac­ tors—access to the right materials and the artistic ability of the dentist. An improved marginal integrity was seen with the alkasite material. Purpose: The purpose of this study was to assess the marginal integrity of composite and glass-ionomer restorations as a function of finishing technique, restorative material and margin location. After finishing, all four factors had a significant influence on the marginal integrity. 0000042292 00000 n 0000058185 00000 n As a result, now you can take your restorative practice to the next level with a new generation of CAD/CAM composites offering high flexural strength, better marginal integrity, fast milling, and tooth-resembling esthetics. 0000017165 00000 n The marginal integrity of each restoration at the four time periods was quantified with a 6‐point photo rating scale.

Marginal integrity of the highest standard The special ORMOCER® compound molecules in Admira Fusion reduce the volume shrinkage to an extremely low level (1.25 % by volume) in conjunction with very low shrinkage stress (3.87 MPa). Table 1 summarized the quality assessment of restorative mate-rials according to certain restoration’s quality criteria, such as: longevity, wear resistance, fracture resistance, marginal adapta-tion, indication, aesthetics, conservation of tooth structure, and a price. 0000047844 00000 n Marginal integrity and microleakage of Direct and Indirect Compos-ite Inlays – SEM and stereomicroscopic evaluation. Tooth-bleaching procedures and their controversial effects: a literature review. During bleaching, hydrogen peroxide (HP) ionizes to release free radicals and nascent oxygen, which break down the larger chromogenic pigments to smaller less intensive ones thereby lightening the color of the tooth (. Comparative microleakage analysis of a newer restorative material – an exvivo study. Ltd., Mumbai, India) formed the experimental bleaching solution (HSP). 37 Amalgam contains a mixture of metals such as silver, copper, and tin, in addition to approximately 50 percent mercury. There is no currently avail- able materials that meet all the requirements for the ideal ma-terial, and each possess its own advantages and disadvantages. These materials are ionic composite resins which combine the biocompatibility, chemical bond and the ability to release fluoride of glass ionomers with the mechanical properties, esthetic and durability of composite resins. This can be ascribed to the presence of enzyme catalase and other antioxidants in SPE (. 0000053887 00000 n Materials and methods: One hundred twenty (120) intact human molars were randomly divided into 12 groups, with three different cavity designs: 1. undermined enamel, 2. box-shaped, and 3. proximal bevel.

MARGINAL INTEGRITY:- The marginal integrity of restorations is an important parameter as marginal gap formation is associated with recurrent caries and pulpal disease. Testing of marginal integrity in vitro is viewed with uncertainty due to interactions and interpretation problems. The aim of this chapter is to describe the armamentarium that can be used to finish and polish different types of restorative material. To overcome this problem, new materials with greater strength were pursued.
