Delayed root canal therapy: an analysis of treatment over time.

A retrospective study of 898 teeth receiving root canal therapy was performed to document the sequelae of delayed completion of root canal treatment. Teeth were categorized into a prompt treatment group and a delayed treatment group. Comparisons of prompt and delayed treatment groups were made with regard to preoperative pain, interappointment emergencies, postobturation pain, and final treatment. Findings from this study show that a palliative endodontic procedure is an extremely effective treatment. However, 56% of teeth with incomplete root canal therapy eventually were extracted compared with 2 to 3% for the root canal filling treatment groups. By emphasizing the potential loss of the tooth rather than the potential of interappointment emergencies, the clinician may be more effective in achieving compliance among patients receiving delayed treatment.

[Clinical observation of one-visit root canal therapy by microwave instrument]

OBJECTIVE:To analysis post-treatmental reaction and long-term effect of one-visit root canal therapy by microwave instrument. METHODS:Applying heat effect and the other ones of microwave,the changes of dentine tissue of extracted teeth were observated by SEM examination.48hs and 1 year post-treatmental effect of 47 patients of periapical periodontitis treated by one-visit root canal therapy were observated and compared with the results of 54 cases treated with common method.RESULTS:In the cases of acute and chronic periapical periodontitis microwave applied in root canal therapy can close the openings of dentine,enhance the effects of sterilization and decrease times of treatment.CONCLUSION:Microwave applied in one-visit root canal therapy is competent.

Success of root canal therapy in HIV-positive patients.

This retrospective study evaluated the success rate of root canal therapy in 157 HIV-positive patients who had undergone nonsurgical endodontic treatment in a dedicated clinic between 1998 and 2004. Dental records and radiographs were reviewed and information concerning age, gender, medical history, anti-retroviral medication, treatment dates, and follow-up evaluation was compiled. All root canal treatment was performed following the clinical guidelines of the American Association of Endodontists. A single practitioner who was responsible for seeing all of the patients at the six-month recall examination reviewed radiographs. Success was defined as the absence of pain and swelling as well as the absence of the periapical lesion (or a reduction in size compared to its preoperative radiographic size). At the six-month postoperative evaluation, a success rate of 90% was observed in the study group. No statistically significant differences were noted when the success of the root canal therapy was related to the symptomatic clinical presentation, the antiretroviral therapy, or the viral load.

Racial variations in dental procedures: the case of root canal therapy versus tooth extraction.

BACKGROUND: Racial disparities have been widely documented in medical care, but variations in dental care have not been well examined. OBJECTIVES: To determine if there is racial variation in use of root canal therapy versus tooth extraction across different levels of dental insurance coverage and adjusting for other factors known to influence treatment decisions. METHODS: Within 3 different categories of insurance coverage, we examined whether there were racial differences in the provision of the tooth-sparing treatment of root canal therapy (vs. tooth extraction) among 54,423 users of outpatient Veterans Affairs dental care in 1998. Regression analyses adjusted for the severity of tooth- and gum-related disease, age, sex, medical and psychiatric comorbidities, prior use of preventive dental services, tooth extraction and root canal therapy, and clustering by geographic region. RESULTS: In the adjusted regression models, black patients and those with unknown race were less likely overall to receive root canal therapy than whites, whereas Asians were more likely. Among patients with eligibility for continuing and comprehensive dental care, blacks were less likely and Asians more likely to receive root canals than whites. For patients covered only for emergency dental care, Hispanics had a higher likelihood of receiving root canal therapy. Among all other types of coverage, there were no significant racial differences in the care received. CONCLUSION: We observed substantial racial variations in the provision of root canal therapy among patients treated in Department of Veterans Affairs dental clinics. Future research should identify the causes of such variations.

Outcomes of vital primary incisor ferric sulfate pulpotomy and root canal therapy.

PURPOSE: To compare ferric sulfate (FS) pulpotomy and primary tooth root canal therapy (RCT) in cariously exposed vital pulps of primary incisors. METHODS: A total of 133 incisors in 50 children were randomly selected to be treated by FS pulpotomy (64) or RCT (69). RESULTS: Two years after treatment, 77 incisors (41 FS pulpotomy, 36 RCT) were available for clinical and radiographic examination. There was no clinical evidence of pathosis in 78% of FS pulpotomy-treated and 100% of RCT-treated incisors. Two independent pediatric dentists evaluated periapical radiographs of the treated incisors. Incisors were classified into 1 of 4 treatment outcomes: N, normal treated incisor; H, nonpathologic radiographic change present; PO, pathologic change present, but not requiring immediate extraction; PX, pathologic change present, extract immediately. Survival analysis was applied. A moderate level of agreement between raters was found for incisors with outcome PX (K = 0.54). Intra-rater reliability was substantial for incisors with outcome PX (K = 0.61). No difference was demonstrated in the proportion of FS pulpotomy- and RCT-treated incisors rated PX at the 2-year recall (x2 = 0.6). RCT incisors demonstrated a significantly higher survival rate than FS pulpotomy incisors at 2 years (p = 0.04). CONCLUSIONS: Treatment outcomes for RCT incisors were not significantly different from FS pulpotomy-treated incisors at 2 years; however, at 2 years the survival rate of RCT incisors was statistically greater than that of FS pulpotomy-treated incisors.
