Zirconia is a polycrystalline ceramic without a glassy phase and exists in several forms. Recently, zirconia has been used to fabricate ceramic fixed dental prosthesis FDPs with relatively high strength and good aesthetics.  The aim of this systematic review was to assess zirconia-based FDPs in terms of survival and complications. Veneering techniques for porcelain application [read the full story…]

Glass fibre-reinforced posts performed better at 5 years in endodontically treated teeth


Post systems are used in the restoration of endodontically treated teeth where there has been significant loss of the clinical crown. A post provides a method to secure filing material to the tooth.  The aim of this trial was to  assess the survival rate of two different post systems after 5 years of service. Patients [read the full story…]

Tooth coloured adhesive filling materials are in common use in dentistry providing good results. However, their success relies on the adhesive systems that provide this bond which has allowed a more conservative approach to cavity preparation.  The aim of this review was to assess the effectiveness of these systems in non-carious cervical lesions (NCCLs).   The [read the full story…]
