“…The results of non‐surgical retreatment in this study (67% by strict criteria and 89% by lenient) were comparable to recent reports (Laukkanen et al, 2019; Signor et al, 2021) and systematic reviews of outcome after non‐surgical retreatment (Ng et al, 2008; Torabinejad et al, 2009). Establishment and maintenance of asepsis, treatment complications and quality of the root filling and coronal restoration are factors considered important for non‐surgical retreatments (Kirkevang & Vaeth, 2020).…”

Aims To evaluate and compare the treatment outcome of root filled teeth with apical periodontitis treated either non‐surgically or by endodontic microsurgery, and to assess the influence of an intra‐radicular post, clinical and demographic factors. Methodology Clinical and radiological data from 1157 patients with apical periodontitis in previously root filled teeth treated by postgraduate students at the Department of Endodontics, University of Oslo, between September 2010 and January 2020 with recall data at least 11 months from completion were studied. Surgical cases were scored using the Rud/Molven criteria and grouped into success, uncertain or failure at control. Non‐surgical cases were scored with the periapical index (PAI) and similarly grouped into success, uncertain or failure at control. Chi‐square analyses were used for comparison of subgroups of teeth treated and logistic regression analyses for assessment of the influence of clinical variables. Results Non‐surgical retreatment was performed on 351 teeth and 107 teeth were treated with endodontic microsurgery, with overall success rates of 65.5% and 77.6%, respectively. The difference was statistically significant. Teeth with an intra‐radicular post treated non‐surgically (n = 30) were successful in 73.3% of cases, whereas teeth with intra‐radicular post treated with endodontic microsurgery (n = 30) had a lower, 66.7% success rate. The distribution of tooth groups (anterior, premolar and molar) differed significantly between surgical and non‐surgical cases, with maxillary anterior and premolar teeth more often treated surgically. Non‐surgical retreatment cases were significantly influenced by patients' age (older patients had poorer outcome) and pre‐operative PAI score (negatively correlated with outcome). Surgical cases were not significantly influenced by the factors studied here. Conclusions The tooth type differed significantly for teeth treated by surgical versus non‐surgical methods. Microsurgical treatment with apicectomy and retrograde filling showed significantly better treatment results than non‐surgical retreatment of teeth with apical periodontitis, whereas treatment outcome in teeth with posts after non‐surgical treatment tended to be better than after surgical treatment. Outcome of non‐surgical retreatment was negatively influenced by older age and higher pre‐operative PAI score.

“…The success rate of primary root canal treatment in teeth with apical periodontitis completed at least 1 year previously ranges considerably, from 68% to more than 85% (Ng et al., 2007). Reported success rates for retreatments vary even more, from 53% to 80% (Jokinen et al., 1978; Ng et al., 2008; Ponsri & Jirathanyanatt, 2022; Signor et al., 2021). We found a success rate by strict criteria of 75% for primary apical periodontitis and 65% for retreatments, corresponding well to data reported in the literature.…”

AimThe aim of this prospective cohort study was to compare the radiographic outcome of endodontic treatment and retreatment of teeth with apical periodontitis using either 1% sodium hypochlorite (NaOCl) or 2% chlorhexidine digluconate (CHX) for root canal irrigation.Materials and MethodsIn the years from 2013 to 2015 standard irrigation varied by semester between NaOCl and CHX at the Department of Endodontics at the Faculty of Dentistry. During that time, 912 teeth received treatment for apical periodontitis in 744 patients, of whom 532 responded to the request for a 1‐year follow‐up. Only one tooth per person (the most distally located) were included; 285 teeth treated with NaOCl and 247 with CHX. One hundred cases were then randomly sampled from each irrigation group and analysed for outcome by periapical index (PAI) scoring using criteria for success, uncertain and failure. Clinical and other radiographic parameters were scored or recorded and analysed for associations with radiographic outcome using chi‐square, ANOVA and regression analyses.ResultsSuccess rates (PAI score 1 or 2 at control) were nearly identical for the two irrigation liquids. The use of irrigating solution also did not significantly influence the outcome in chi‐square analyses of subgroups of teeth or regression analyses with other variables included. Ordinal regression analysis established that preoperative lesion size or preoperative PAI score were significantly associated with outcome, and teeth in the mandible had significantly better outcomes than in the maxilla.ConclusionsNo significant differences in the radiographic outcome using either 1% NaOCl or 2% CHX as irrigants were found. The outcome was better for teeth with small lesions or lower PAI scores at completion of treatment and for mandibular teeth.

Observational studies play a critical role in evaluating the prevalence and incidence of conditions or diseases in populations as well as in defining the benefits and potential hazards of health‐related interventions. There are currently no reporting guidelines for observational studies in the field of Endodontics. The Preferred Reporting Items for study Designs in Endodontology (PRIDE) team has developed and published new reporting guidelines for observational‐based studies called the ‘Preferred Reporting items for OBservational studies in Endodontics (PROBE) 2023’ guidelines. The PROBE 2023 guidelines were developed exclusively for the speciality of Endodontics by integrating and adapting the ‘STrengthening the Reporting of OBservational studies in Epidemiology (STROBE)’ checklist and the ‘Clinical and Laboratory Images in Publications (CLIP)’ principles. The recommendations of the Guidance for Developers of Health Research Reporting Guidelines were adhered to throughout the process of developing the guidelines. The purpose of this document is to serve as a guide for authors by providing an explanation for each of the items in the PROBE 2023 checklist along with relevant examples from the literature. The document also offers advice to authors on how they can address each item in their manuscript before submission to a journal. The PROBE 2023 checklist is freely accessible and downloadable from the PRIDE website (http://pride-endodonticguidelines.org/probe/).
