objectives: this study aimed to compare the shear bond strength (sbs) of composite to stainless steel crowns (ssc) using two mechanical surface treatments (msts) and two bonding systems. materials and methods: eighty-four sscs were divided into six groups of 14; group1: no mst+scotchbond universal adhesive (n+u), group 2: surface roughening by a diamond bur+scotchbond universal adhesive (r+u), ...

statement of problem: shear bond strength (sbs) of home and office bleached enamel will be compromised by immediate application of composite restoration. antioxidant agent may overcome this problem. objectives: this in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. materials and methods: in this experimental ...

this study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal preventive resin restoration (prr). the purpose of the present study was to assess the microleakage at amalgam-composite interface and composite-composite interface in permanent tooth with prr.thirty-five premolar te...

Collapse in the anterior maxillary region is one of the most frequently found problems in patients who have endured extractions, especially in zones which represent a great aesthetical challenge. Treatment is often administered lacking proper case planning, and therefore might originate very important defects in the alveolar process periodontal architecture. There are periodontal and prosthetic...

UNLABELLED The provision of fixed prosthodontic restorations that meets the patient's functional and aesthetic demands can be challenging, especially in the anterior maxilla. It requires close communication with the technician and knowledge of the available options. This article will outline the options for pontic design and focus on the ovate pontic, which has the potential to provide the most...

The loss of anterior teeth can be hurtful to the patient both psychologically and socially. As the children are becoming more aware these days, they have also become conscious about their looks. Early loss of deciduous anterior teeth has a psychological effect on many children. In such young patients, paper replacement of the teeth can minimize these concerns. Many approaches have been describe...

Limpet teeth are striking examples of a biological fibrous nanocomposite consisting of goethite mineral within a polymeric chitin matrix. The mechanical function of limpet teeth is critically dependent on the efficient composite behaviour of goethite, formed as distinct discontinuous nanofibres, reinforcing the matrix. The mechanical properties of discrete volumes from a limpet tooth measured u...

Sudden tooth loss in the esthetic zone of maxillary or mandibular anterior region can be due to dental trauma, endodontic failure, extensive root resorption, advanced periodontal disease. The treatment options for replacing missing vary between removable temporary acrylic prosthesis, Resin-bonded bridges, Traditional metal, and ceramic fixed partial denture, implant-supported prosthesis. Irresp...
