Abstract Aim To determine retrospectively the clinical and radiographic success rate of single‐visit root canal treatment performed in a busy endodontic practice using contemporary techniques of canal cleaning, shaping and obturation. Summary Seven hundred and sixty‐eight single‐visit cases, of which 223 presented for a re‐examination appointment ranging from 6 months to 4 years from the day of treatment, were considered. Four endodontists provided examinations for both root canal treatment and re‐examinations. Clinical and radiographic data were used to form an overall impression of the outcomes for each case at the time of re‐examination. Available demographics and treatment information of these 223 cases were compiled for comparison. The number of treatment visits was not determined by a pretreatment diagnosis or a re‐assessment of the pulp status upon entry into the tooth; therefore both vital and necrotic cases, as well as those with and without periradicular pathosis, were included. Statistical analysis was carried out using Chi‐square tests and considered variations in failure rates based on gender, provider, tooth type, position and arch. A t ‐test was used to evaluate data on age. The overall success rate was 89.2%. No statistically significant differences were seen based on gender, age, arch or provider. Statistically, anterior teeth were more successful than posterior teeth. Key learning points • The success rate of single‐visit root canal treatment in this study is comparable to previous studies of teeth treated in a single visit, as well as those treated in multiple visits, with the placement of interappointment calcium hydroxide. • The provision of single‐visit root canal treatment using modern techniques of root canal cleaning, shaping and obturation can be considered as a viable method for the retention of natural teeth within contemporary treatment planning concepts. • Future studies on the outcomes of contemporary endodontic treatment should be designed and implemented to use prospective, randomized clinical trials in which the re‐examination rate is high.
