Clinical factors related to noncompletion of root canal therapy.

OBJECTIVES: This study identified clinical factors related to noncompletion of root canal therapy (RCT) among patients in a dental health maintenance organization (HMO) based in Portland, OR. METHODS: A secondary analysis of a case-control study was conducted using data from 303 individuals enrolled continuously in the HMO from January 1, 1987, through December 31, 1994, who received endodontic access on a permanent nonwisdom tooth in 1987 or 1988. Person- and tooth-level characteristics were evaluated to compare patients whose accessed tooth was obturated by December 31, 1994, with patients whose accessed tooth was not obturated by that date. Written and electronic records were reviewed to ascertain study variables, and multivariate logistic regression models were developed to describe differences between the two groups. RESULTS: Incomplete RCT was more common among patients who were symptomatic prior to access and had more missing first molars at access. It also was more common among teeth that were decayed, had more pockets > or = 5 mm, and had fewer decayed or filled surfaces at access. CONCLUSIONS: Because patients with greater evidence of past and current oral disease were less likely to have completed RCT, they may require additional counseling about the importance of carrying through with prescribed treatment.

[Analysis of short-term pain occurrence applying different materials for root canal therapy].

OBJECTIVE: The aim of this study is to compare the occurrence of pain applying different materials of root canal therapy in vital teeth. METHODS: 288 vital teeth were divided into 4 groups, Cortisomol sealer+gutta-percha and Vitapex+gutta-percha were used respectively in 2 groups of one time method; while Cortisomol sealer+gutta-percha and Vitapex+gutta-percha were used after 24-48 hours drainage in the other 2 groups. The occurrence of pain after 1 week was recorded. RESULTS: In all treated teeth,the occurrence rate of self-healing pain after root canal therapy was 22.6%, the occurrence rate of non-self-healing was 2.08%; in the groups of one time method,the occurrence rate of pain using Cortisomol was lower than the group using Vitapex with significant difference(P<0.01); while in the groups of root canal filling after drainage,the occurrence of self-healing pain in the group using Cortisomol was lower than the group of using Vitapex without significant difference(P>0.05);the pain occurred within 72 hours in most of the teeth. CONCLUSION: Root canal treatment applying Cortisomol sealer+gutta-percha can decrease the rate of pain occurrence after root canal filling.
