Factors Effecting Survival Of Teeth With Nonsurgical Root Canal Therapy Including A Multi-State Outcome Analysis, Alex Moore
Master's Theses (2009 -)
Objective: To study the factors effecting the survival of teeth with non-surgical root canal therapy (NS-RCT) and to compare the transitions between failure states for teeth treated with NS-RCT based on initial provider type. Methods: Insurance claims were analyzed for 438,487 initial NS-RCT procedures to determine the effect of provider type, patient age, tooth position, presence of post/core, and crown at 90 days on tooth survival. Kaplan Meier survival estimates were evaluated for 1, 3, 5, and 10 years and adjusted hazard ratios (aHR’s) were calculated. A multi-state model with six transitions was created using the ‘mstate’ R package. Results: …
