We read with interest, Professor Burke's comments about our research article, reporting on the performance of directly bonded resin composite restorations placed at an increased occlusal vertical dimension for the treatment of generalized tooth wear.1 This research forms part of the overall Radboud Tooth Wear Project (RTWP), Radboudumc, Nijmegen, the Netherlands. In recent times, there has been much interest in the subject of tooth wear, especially given the known prevalence and impact of this condition on patients,2,3,4 and we are delighted to read about the Editor's interests in our work.
As part of the 2017, European Consensus Statement on the Management Guidelines for Severe Tooth Wear,5 when restorative intervention is indicated, a conservative and minimally invasive approach is recommended. Several studies have reported the performance of resin composite for the treatment of tooth wear; however, the data has been limited to relatively smaller sample sizes and/or shorter observation periods. Our study included a sample of patients with generalized moderate to severe tooth wear, where full mouth restorative treatment was indicated. In total, 1269 restorations were prescribed. Patients with potential risk factors for tooth wear such as severe bruxism or a marked gastro-oesophageal reflux, were not excluded. The patients were observed for a mean period of 62.4 months. With the relatively low annual failure rates reported (up to 2.2% and 2.9% for the anterior and posterior restorations, respectively) as well as a low overall rate of catastrophic failure (2.3%), it was concluded that this approach was justified for the medium-term treatment of patients with generalized tooth wear. We do hope that the outcomes of our investigation may help colleagues develop a better understanding of this contentious subject area.
