(PR138) The 10-year Survival Rate of Initial Nonsurgical Root Canal Therapy on Adults Aged 65 and Over: A Retrospective Study

Objective: The average age of the world population is ever-increasing, and so is the desire for tooth retention. While there have been several systematic reviews concerning the appropriate considerations for nonsurgical root canal therapy in older adults, there is still a lack of evidence-based data concerning this topic. To increase our understanding of NSRCTs using modern materials and techniques in patients of advanced age, it is necessary to analyze the available existing data. The object of this study is to determine the survival rate of initial NSRCT in patients 65 and over.

Methods: This study included initial NSRCTs performed on patients of record ≥65 years of age from 2007-2013 at Southern Illinois University. Each tooth was assessed for survival at 10 years post treatment.

Results: >99 cases of initial NSRCT were assessed. The survival rate was 56.6 after 10 years. Data will be further analyzed to determine if extraction was due to endodontic failure, or restorative reasons.

Conclusion: Findings indicate that initial NSRCT is a viable long term treatment option for older patients, but the survival is less than that of the general population. More research is needed in order to determine the reason for extraction of teeth treated with initial NSRCT and to improve treatment outcomes in the older population.
