Abstract
Aim
It is the aim of this paper to present data on the survival of resin composite restorations by analysis of the time to re-intervention on the restorations and time to extraction of the restored tooth, and to discuss the factors which may influence this.
Results
Data for more than three million different patients and more than 25 million courses of treatment were included in the analysis. Included were all records for adults (aged 18 or over at date of acceptance). Overall, 3.5 million restorations in resin composite were included, of which over 1.3 million had a re-intervention over the 15-year duration of the dataset. Kaplan-Meier analysis indicates that circa 34% survive 15 years without re-intervention, and circa 83% without extraction. Variation by tooth position, dentist characteristics, patient characteristics and associated treatment were explored.
Conclusions
Overall, around 34% of resin composite restorations teeth have survived at 15 years, with factors influencing survival including patient age, dentist age, and patient treatment need.
