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…]
