Abstract
Objective: To determine if there is a difference in the survival of implant and root canal treatments completed in a dental school setting over a 3-year time period. Materials/Methods: This was an IRB approved retrospective study of implant and root canal (RCT) survival using existing data. We identified patients who received either or both treatments in 2005-2006 at the Henry M. Goldman School of Dental Medicine and followed them for three years after placement. Patient records (physical and electronic) were used to collect information on patient age, insurance, gender, medical conditions, type of tooth (anterior, premolar and molar) and treatment. Survival was defined as when the tooth or implant was in the mouth and did not require a retreatment, surgery, or removal. Data were double entered, cleaned, and cross referenced as needed to ensure accuracy. Simple and multivariable regression modeled survival at 1, 2 and 3 years by treatment type (RCT versus implant). Results: A total of 568 implants and 688 root canals were completed on 788 patients. The 1, 2, and 3 year survival rates for RCT were 95.64%, 93.46%, 92.15%; for implants survival rates were 97.59%, 97.22%, 91.28%. At 1 year there was a borderline difference in the survival of implants compared to root canals (p=0.0655). At two years there was a significant difference in survival in favor of implants versus root canals; p =0.0025. At 3 years there was no significant difference in survival of implants versus root canals. At 3 years, being on Medicaid, number of medications, and number of RCT were significant covariates for lowering survival rates for root canals. At 3 years, number of medications increased the survival of implants and history of arthritis/joint pain were significant covariates for lowering implant survival rates. Conclusion: There was a borderline difference in survival favoring implants at 1 year, a significant difference in favor of implant survival at 2 years, and no difference at 3 years for implant and root canal survival.
