Received: January 03, 2017; Accepted: January 11, 2017; Published: January 14, 2017 Biofilm acids lead to secondary caries, which is a main reason for dental restoration failures. Incorporation both protein-repellent and antibacterial agents into dental composite resulted in a much greater inhibition in biofilm activity. This new class of bioactive dental composite with antibacterial and protei...

Repeated symmetry-breaking and restoration phase transitions occur as one traverses the parameter space of interactions competing to align the vacuum. This phenomenon, augmented with a topcolor-like interaction, can make a composite Higgs boson’s mass and vacuum expectation value naturally much less than its underlying structure scale, without introducing new symmetries and their associated TeV...

A definitive cavity design, without pins, that enhances retention and resistance form for simple and complex Class IV composite restorations is proposed. An extracted tooth model and diagrams illustrate the incisal step 4 5 O bevel design for simple cavities and the incisal step veneer bevel design for complex cavities. A case report of a complex Class IV composite restoration is presented. (Re...

Endodontically treated teeth can be restored with a wide range of techniques of varying complexity. This paper presents a straightforward technique for the restoration of endodontically treated teeth that meet certain standards. Criteria are provided for the utilization of crowns, composite resins, cast gold post cores, amalgam or composite build-ups, and passive, parallel, small diameter stain...

This in vitro study investigated strain produced in the placement and polymerization of Class II posterior composite resin restorations in primary teeth. Mesio-occlusodistal preparations were placed in primary teeth, followed by posterior composite resin restoration placement, using 3 different application techniques (technique I--placement and polymerization in 1 complete unit; technique II--p...

o bjectives: caries and dental trauma are common reasons for primary anterior teeth restorations in children. this non-control clinical trial was designed to eva- luate crown restorations reinforced with a sectioned file post for the restoration of severely damaged primary maxillary incisors. materials and methods: thirty-eight primary maxillary incisors of 12 children (3-5 years old) with earl...

AIM The purpose of this study was to investigate the effect of different temperatures on the efficacy of polymerization during the insertion of composite resin using different light curing units. METHODS AND MATERIALS A total of 45 disc-shaped specimens were fabricated from Z250 composite resin (3M/ESPE, St. Paul, MN, USA) with 15 each prepared at three different temperatures (refrigerated to...

abstract: introduction: ditching and marginal defects of amalgam restorations can cause microleakage, recurrent carries, pulp hypersensitivity and finally loss of the tooth. the complete replacement of large restoration is time consuming, difficult and may potentially damage the pulp. therefore in cases were there is no sings of recurrent caries, composite repair can be chosen as an alternative...

periodontal disease, or endodontic failure is a true esthetic emergency for a patient. A missing anterior tooth has implications for how we present ourselves to others and affects how we feel about ourselves. If the tooth or tooth crown is still intact and the patient brings it with them to the dental office, it is easiest to use it as a natural tooth pontic, joining it to the adjacent teeth wi...

AIM Although the demand for aesthetic restoration of primary molars has increased, techniques for producing aesthetic, direct full-crown restorations using light-cured composite resin for primary molars and the associated clinical outcome are not well established. The aim of this study was to describe the use of new techniques to produce aesthetic, direct full-crown restorations using light-cur...
