   Root canal treatment (Wikipedia)

   “Root canal treatment (also known as endodontic therapy, endodontic treatment, or root canal therapy) is a treatment sequence for the infected pulp of a tooth—an abscess—that is intended to result in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion. It is generally done when the cavity is too big for a normal filling. Root canals, and their associated pulp chamber, are the physical hollows within a tooth that are naturally inhabited by nerve tissue, blood vessels and other cellular entities. Endodontic therapy involves the removal of these structures, disinfection and the subsequent shaping, cleaning, and decontamination of the hollows with small files and irrigating solutions, and the obturation (filling) of the decontaminated canals. Filling of the cleaned and decontaminated canals is done with an inert filling such as gutta-percha and typically a zinc oxide eugenol-based cement. Epoxy resin is employed to bind gutta-percha in some root canal procedures. In the past, in the discredited Sargenti method, an antiseptic filling material containing paraformaldehyde like N2 was used.”

   “There was no evidence of a survival difference between pathways (log-rank p = 0.785). Implant replacement was not associated with a lower adjusted hazard of failure (hazard ratio [HR] 0.87; 95% confidence interval (CI) 0.47-1.62; p = 0.666), whereas current tobacco use increased failure risk (HR 2.01; 95% CI 1.05-3.86; p = 0.036). Patient-reported oral health-related quality of life (OHRQoL) and satisfaction were comparable. IMPLANT involved more visits, greater downtime, and higher initial, total observed, and cost-per-year-of-function expenses (all p ConclusionIn this private-practice cohort, appropriately indicated tooth preservation and implant replacement demonstrated comparable survival and patient-reported outcomes within the observed follow-up period. The two options should not be treated as interchangeable substitutes; rather, selection should be individualized according to restorability, ferrule feasibility, periodontal and occlusal risk, strategic value, patient preference, maintenance burden, and cost trajectory.”

   Factors Influencing Tooth Preservation Decisions among U.S. General Dentists: A Cross-sectional Vignette Study.

   “Clinician-related variables were evaluated as follows: age, gender, years of experience, primary practice setting, and participation with payment systems. Kruskal-Wallis tests were used to compare the treatment decision with Likert-scale responses for clinical decision-making. A logistic regression model investigated the effect of clinician factors on the treatment decision.ResultsOne hundred thirteen eligible dentists completed the survey. For the presented case, a maxillary first molar, 54% of general dentists recommended initial RCT, and 46% recommended extraction. 37.2% of dentists responded that the patient's tooth was somewhat or very likely restorable. None of the evaluated clinician factors were statistically significant in predicting the treatment decision. Borderline significance (P = .05) was noted for general dentists primarily practicing in academic settings; they had 3.57 times the odds of recommending tooth extraction than dentists primarily in private practice (P = .05).ConclusionsThis study found that general dentists' decision to either save a tooth with initial root canal therapy or extract was primarily associated with perceived tooth restorability.”

   Evaluation of Treatment Decision-Making for Teeth with Post-Treatment Apical Periodontitis Among Dental Students, General Dentists, and Endodontists in Chile.

   “GDP and DS were significantly more likely to recommend extraction (p < 0.001 for both), particularly among GDPs aged 36-45 years (p = 0.003) and those working in the public sector. All tooth-related variables significantly influenced decisions. Teeth with indirect restorations were associated with higher extraction rates, especially among GDP (p < 0.001). Inadequate root canal fillings significantly increased extraction decisions by GDPs (p < 0.001). GDPs also had a strong tendency to extract teeth with medium (p < 0.001) and large apical lesions (p = 0.001).ConclusionsSignificant differences were observed across professional groups, with E demonstrating a greater tendency toward tooth preservation. Improving clinical decision-making in undergraduate and continuing dental education may help reduce unnecessary extractions and support evidence-based health planning in underserved areas with limited access to specialist care.”

   Root canal treatment vs implants: Survival and costs in a national cohort.

   Journal of dentistry (Mota et al.)Published Aug 25, 2026Checked Oct 17, 2026

   “RMST was 5.8 yrs for ENDO and 6.6 yrs for IMPLANT and respective mean cumulative costs were USD 1243 and USD 2667. With the exception of mandibular anterior sites, IMPLANT showed longer mean function times. The overall ICER was USD 1874 per yr gained, ranging from USD 1352 (maxillary molar sites) to USD 4836 (maxillary anterior sites).ConclusionsOverall, survival and function time of implants replacing endodontically diseased teeth was greater than that of teeth following root canal treatment. Cumulative costs were higher for implant therapy. At mandibular anterior sites, however, root canal treatment resulted in higher survival and function time, at lower costs.Clinical significanceWhile implant-based tooth replacement provided greater survival and function time than root canal treatment in general, benefits came at considerably higher cumulative costs. Site-specific differences were also evident as root canal treatment at anterior sites in the mandible resulted in both higher survival and lower treatment costs.”

   Root Canal Therapy Versus Single-Tooth Dental Implants for Compromised Teeth: A Retrospective Comparative Study.

   “Effect estimates are reported with 95% confidence intervals (CIs). Statistical significance was set at p ResultsTreatment survival was 100% following RCT and 96% following implant treatment (risk difference: 4.0%, 95% CI: -3.7 to 13.5; p = 0.495). Clinical and radiographic success did not differ significantly. Biological complications were less frequent after RCT than after implant treatment (4% versus 20%; risk difference: -16.0%, 95% CI: -29.4 to -3.1; Fisher's exact test, p = 0.028). RCT was associated with fewer visits (mean difference: -2.12, 95% CI: -2.47 to -1.77), a shorter treatment duration (-87.10 days, 95% CI: -96.57 to -77.63), and a lower direct cost (-INR: 29,966, 95% CI: -32,203 to -27,729); all p ConclusionsBoth treatments demonstrated favorable short- to intermediate-term outcomes. In this retrospective cohort, RCT was associated with fewer biological complications, lower treatment burden and cost, and higher satisfaction. Because treatment was not randomized, these associations may partly reflect treatment-selection differences, and natural-tooth preservation should be considered when a compromised tooth remains predictably restorable.”
