“…Al‐Nuaimi et al . () concluded that a favourable outcome was more likely when at least 30% residual tooth structure was present at the commencement of root canal retreatment. In a pooled analysis of 354 root filled teeth (123 primary treatments and 231 retreatments), the success rate for root canal treatment was lower when assessed using CBCT compared to PR.…”

The use of cone beam computed tomography (CBCT) in the diagnosis and/or management of endodontic problems is increasing and is reflected in the exponential rise in publications on this topic in the last two decades. The aim of this paper is to: (i) Review current literature on the endodontic applications of CBCT; (ii) Based on current evidence make recommendations for the use of CBCT in Endodontics; (iii) Highlight the areas in which more research is required.

“…The majority of the clinical studies assessing the outcome of root canal treatment have only analysed the effect of individual variables on post-treatment healing (Ørstavik et al 2004). In order to improve understanding on this essential issue, several clinical studies have evaluated multiple predictors of outcome (Friedman et al 2003, de Chevigny et al 2008, Liang et al 2011, Fern andez et al 2013, Touboul et al 2014, Davies et al 2015, Al-Nuaimi et al 2017). However, except for some studies (Patel et al 2012, Fern andez et al 2013, Davies et al 2015, Al-Nuaimi et al 2017, Nascimento et al 2018) only periapical radiographs have been used in most previous outcome studies.…”

Prognosis of root canal treatment in teeth with preoperative apical periodontitis: a study with cone‐beam computed tomography and digital periapical radiography

Aim This observational cohort study aimed: (i) to determine retrospectively after a 1‐ to 12‐year follow‐up period, the strength and independence of the association of various patient‐, tooth‐ and treatment‐related prognostic variables with the outcome of root canal treatment in patients with pre‐therapeutic apical periodontitis; and (ii) to establish the concordance between those predictors evaluated by both cone‐beam computed tomography (CBCT) and digital periapical radiography (DPR). Methodology The study cohort included 125 teeth in 84 individuals. The postoperative clinical signs/symptoms, plus DPR/CBCT‐PAI estimations, were used to determine the healing outcome. For statistical analysis, results were dichotomized into completely healed periapical structures versus persistent disease cases. The association between candidate predictor variables with persistent disease was analysed individually and adjusted for confounders using a multivariate binary logistic regression model. Results The success rate was 53.6%. After logistic regression analysis, mandibular tooth location, periapical lesion size >10 mm, poor quality of the coronal restoration, lack of magnification/illumination, lack of disinfection of gutta‐percha, time elapsed to definitive coronal restoration >1 week and poor density of root canal filling remained as robust predictors of failures. Concordance between DPR and CBCT scores varied from moderate to almost perfect agreement. Conclusions The findings of this study suggest that several tooth‐ and treatment‐related predictor variables, including tooth location, periapical radiolucency size, quality of the coronal restoration, magnification/illumination, disinfection of gutta‐percha, time elapsed to definitive coronal restoration, as well as, the density of root canal filling may act strongly and independently for determining the root canal treatment outcome in teeth with pre‐therapeutic apical periodontitis.

“…Ethical approval by the Health Research Authority, UK (IRAS: 233932) was gained to collect patient data from the clinical records of patients who had already been successfully recruited as part of a prospective cohort study, which investigated the outcome of retreated posterior teeth with varying degrees of coronal tooth structure loss (Al‐Nuaimi et al ).…”

“…The amount of residual tooth structure is one of the most important parameters determining the survival of (re-)treated teeth (Reeh et al 1989, Gulabivala 2004, Nagasiri & Chitmongkolsuk 2005, Ng et al 2006, Creugers et al, 2012, Al-Nuaimi et al 2017. Teeth diagnosed with endodontic disease often lack structural integrity and are compromised as a result of caries, existing restoration(s), cracks and fractures (Larson et al 1981, Eakle et al 1986, Tan et al 2006).…”

Aim To assess the effectiveness of the Dental Practicality Index (DPI) in predicting the outcome of root canal retreatment in posterior teeth. Methodology One hundred and thirty‐seven posterior teeth with symptoms and/or signs of post‐treatment endodontic disease requiring root canal retreatment and previously included in a clinical trial were selected. Clinical and radiographic examinations including digital periapical and cone beam computed tomography (CBCT) were obtained pre‐treatment and 1‐year postoperatively from a previous study. Two calibrated and trained assessors who were unaware of the treatment outcome assessed the pre‐treatment clinical records of these cases using the DPI. The DPI score was then compared to the outcome of the root canal retreatment. A Chi‐square/Fisher’s exact test was used to establish a relationship between categorical variables, the total score of DPI vs outcome. Results Retreated teeth with DPI scores equal to 6 or above had an unfavourable outcome of 50% vs 14% of teeth with DPI below 6. Teeth with DPI score equal to 3 or above had an unfavourable outcome of 23% versus 2%, for teeth below 3. Molar teeth with a DPI score below 3 had a favourable outcome percentage of 96%. Conclusions This study highlighted that using the DPI gave a good outcome prediction for root canal retreatments. However, further research, including the prospective assessment of a wider range of cases undertaken by a larger group of examiners is needed to further validate the DPI.
