Coronal fractures of the anterior teeth are a common form of dental trauma. If the original tooth fragment is retained following fracture, reattachment of the fractured fragment to the remaining tooth can provide better and long-lasting esthetics, improved function, a positive psychological response and is a faster and less complicated procedure. This paper reports on two coronal tooth fracture...

Background: Luting agents used to fix artificial prostheses, such as fixed partial denture (FPD) to tooth are basically viscous in nature and show chemical reaction for fixation. Postcementation hypersensitivity is a frequent complaint of patients. The present study was conducted to compare postcementation hypersensitivity with zinc phosphate and self-adhesive resin in complete coverage crown. ...

Graphene is the thinnest, strongest and stiffest imaginable material. The biocompatible property of graphene oxide can initiate facilitate cell adhesion, proliferation differentiation periodontal ligament, osteogenic oral epithelial cells. Furthermore, antibiofilm anti-adhesion properties in prevention dental biofilm infections, caries, erosion as well for implant surface modification an...

Copper deficiency resulting in hypocupremia is a rare cause of pancytopenia associated with a neurological syndrome. Hypocupremia may also occur as a consequence of excessive oral zinc consumption as described by Brewer et al and several other groups. Dental fixatives have been described as a potential source of hyperzincemia in patients. Despite the recently modified dental fixatives with safe...

This study examined the extent of organic solvent and water retention in comonomer blends with different hydrophilicity (Hoy’s solubility parameter for hydrogen bonding, δh) after solvent evaporation, and the extent of tracer penetration in polymerised films prepared from these resins. For each comonomer blend, adhesive/solvent mixtures were prepared by addition of [1] 50wt% acetone; [2] 50wt% ...

BACKGROUND Regardless of the technique and the material used, the goal of obturation remained the same that is to seal every portal of exit in the root canal system. It's not only the apical openings that need to be sealed but also lateral openings, coronal access opening and perforations if they exist failure of the adhesive root canal sealer has led to the idea of usage of dentin bonding agen...

The development and reliability of adhesive resin composite systems have offered clinicians a further option for the management of tooth-surface loss. Patients with minimum, moderate, and severe hard tissue wear can be treated based on the application of minimally invasive adhesive composite restorations for posterior and anterior worn dentition. This article presents the "index technique", a n...

OBJECTIVES Endodontically treated teeth with insufficient tooth structure are often restored with esthetic restorations. This study evaluated the cytotoxicity and biological effects of yttria partially stabilized zirconia (Y-TZP) blocks in combination with several dental cements. MATERIALS AND METHODS Pairs of zirconia cylinders with medium alone or cemented with three types of dental cement ...
