Cervical restoration of a premolar tooth is challenging task as it involves structural modification to ensure the functional integrity tooth. The lack retention in cervical area, with cavity margins on dentin and nonavailability enamel, makes for restoration. high organic content dentin, along its tubular structure outward flow fluid, make bonding difficult attain. objective this study evaluate...

OBJECTIVE Re-examining the well accepted concept that Zinc-Oxide-Eugenol bases (ZOE) have a negative effect on composite restoration materials microhardness, in light of the advancement in composite materials and newer publications. METHODS Five modern composite restoration materials were used, including hybrid (Xtra-fill and Z250), micro-fill hybrid (G-aenial and Gradia-direct) and methacryl...

immediate restoration after vital pulp therapy is essential in order to create and maintain effective coronal seal.the aim of this study was to evaluate the shear bond strength of recently used pulp capping materials: white mineral trioxide aggregate (mta), and calcium enriched mixture cement (cem) to composite resin with the use of etch-and-rinse and self-etch adhesive systems and compare them...

Secondary caries, the lesion at the margin of a restoration, has been widely considered as the most important and common reason for restoration replacement, regardless of the restorative material type [Collins et al., 1998; Dahl and Eriksen, 1978; Deligeorgi et al., 2001; Friedl et al., 1995; Mjör, 2005; Mjör and Toffenetti, 2000;]. As it develops after the initial caries has been removed and r...

BACKGROUND Hair restoration surgery has evolved into a scientifically based cosmetic surgical discipline over the last half century. A recent hair surgical technique to evolve, Follicular Unit Extraction (FUE), is a donor harvesting technique removing single "follicular units "one unit at a time" with a small round punch. OBJECTIVE Describe the origins, current practices and controversies in ...

Amalgam has been used in the restoration of structurally compromised posterior teeth for many years. When placing large amalgam restorations, replacement of weak cusps with restorative material is recommended to prevent tooth fracture. This recommendation can be modified with new guidelines using modern adhesive techniques. Semidirect and indirect inlay/onlay composite restorations have progres...

UNLABELLED The restoration of posterior teeth with directly placed resin-bonded composite requires meticulous operative technique in order to ensure success. Case and material selection; cavity preparation; matrix selection; isolation; bonding; management of polymerization shrinkage; placement; finishing and curing of posterior composites--all present a series of challenges that dentists must m...

Wood as a natural organic material is susceptible to biodeterioration by insects, fungi, and bacteria. There is almost no wooden artefact or old wooden element, which is not infected and not damaged, at least partly, by wood-destroying organisms. As ancient wood and wooden artefacts are invaluable, their appropriate restoration is of particular importance. The first step in restoration is the d...
