3-Year Survival of direct composite resin restorations of permanent first molars with excessive material loss in children

Abstract

Aim: The aim of this retrospective study was to determine survival rates of direct composite resin (DCR) restorations of permanent first molars (PFMs) with excessive material loss at the end of 3 years. Material and methods: Children between the ages of 7-14 whose PFMs had 3-surfaced DCR restoration were included in the study. In restorations Ionofil Molar glass ionomer cement (VOCO,Cuxhaven,Germany) as base material, Clearfil SE Bond adhesive agent and Clearfil Majesty Posterior composite resin (Kuraray Noritake Dental Inc.,Okayama,Japan.) were used. Survival rates of the restorations after 3 years were evaluated using The United States Public Health Service criteria and the presence of symptoms indicating irreversible pulp damage and the need for root canal treatment such as provoked or spontaneous pain, percussion, abscess, fistula in the related teeth were examined clinically and radiographically. Chi-square and Kruskal Wallis analyzes were used for the statistical analysis. Results: Totally 58 DCR restorations of PFMs of 34 patients who agreed to come for the control visit at the end of 3 years were examined. The survival rate of restorations was 70.69% and findings indicating irreversible pulp damage were found in 15.5% of the restorations examined. Conclusion: Survival rate of DCR restorations applied to PFMs with excessive material loss is not satisfactory after 3 years, however it is thought that DCR applications will continue in PFMs with excessive material loss thanks to the developments in adhesive systems and composite resins. Therefore, long-term randomized controlled clinical studies on this subject should be continued.
