For covering of hypersensitive, morphologically disturbed and non-esthetic cervical (wedge-shaped) defects of hard dental tissues, dentine adhesive composite systems are suitable for a careful and less invasive preparation. Presumption is a smooth and at probing hard-touched defect surface. A clinical 2 year study (15 patients with 143 cervical lesions) using 5 different dentine adhesive composite systems resulted in superiority of the hybrid composite P-30 in view of low filling losses (after 1 year: 1 of 28 fillings after 2 years: 2 of 27 fillings), the acceptable bond zone morphology (after 1 and 2 years clinical intact bond zones), and a constant volume behaviour (after 1 and 2 years no clinical changes of volume). The micromorphological evaluation correlated in a lot of cases with the clinical findings after 2 years. It has to be expected that improved dentine adhesive composite systems together with changed setting mechanisms of dentine adhesives will be able to eliminate filling losses in the treated indication.
