Two-Year Healing Success Rates after Endodontic Treatment Using 3D Cleaning Technique: A Prospective Multicenter Clinical Study

Abstract

Background: Various irrigation techniques for cleansing the endodontic space have been proposed, and internal heating combined with ultrasonic activation (3D cleaning technique) is considered an effective technique. This prospective multicenter clinical study aims to evaluate healing rates for teeth after root canal treatment utilizing the 3D cleaning technique and to report predictive values for success. Material and Methods: Ninety patients referred for a root canal treatment were included. All enrolled patients were treated with the 3D cleaning protocol. Four endodontists performed the clinical procedures and follow-up evaluations. Preoperative, postoperative and follow-up data were gathered from the consented patients. Each patient was assessed for any clinical signs or symptoms. Afterwards, two trained, blinded, and independent evaluators scored the subject’s periapical radiographs. This score was made by checking for the presence or absence of apical periodontitis using the periapical index (PAI). Then, the teeth were classified as healing or healed and were considered a success based on a cumulative success rate of healing. Statistical analysis was performed using the Fisher’s exact test, Pearson correlation, and logistic regression analyses of the preoperative prognostic factors at a 0.05 significance level. Results: 90 patients were evaluated at two years with a follow-up rate of 97.7%. The cumulative success rate of healing was 95.4%. Eight predicting aspects were identified by employing bivariate analyses. Then, using logistic analyses, the two prognostic significant variables directly correlated to healing were the preoperative presence of periapical index (p value = 0.016). Conclusions: In this two-year clinical study, the cumulative success rate of healing was 95.4% when patients were treated with the 3D cleaning protocol.

Intentional Replantation of Single-Rooted and Multi-Rooted Teeth: A Systematic Review

“…Remarkably, however, the teeth in these cases were stored in a moist environment to preserve the viability of the PDL cells [3,7,8,[11][12][13]18,19,90], suggesting that extra-alveolar stay time should be considered in the context of tooth conservation approaches. In this context, it has been previously suggested [8,10,91] that preservation of the tooth in an extra-oral humid environment, such as water, saline, and saliva, may positively influence the results of IR, making the procedure more predictable and thus supporting the hypothesis that the periodic submersion of the tooth in a bath of Hank's balanced salt solution during the root resection phase may be the best approach to avoid root desiccation [91].…”

Dentinal tubule penetration following ultrasonic, sonic, and single-cone technique of a biosealer: An ex vivo study

“…Consequently, a better obturation phase with an adequate apical seal (both lateral anatomies and dentinal tubules) increases the success rates of endodontic treatment. [ 23 24 ] The protocol adopted in this article aims to accomplish this result, which, from the data that emerged, is achievable with the activation of bioceramic cement utilizing ultrasonic tips.…”

“…Thus, remnant tissue and biofilms in such anatomies could be an infection source. [ 84 ] From this perspective, irrigant activation methods could be used to increase the efficacy of disinfection in root canals. [ 21 ] Irrigant activation can consist of several methods, such as subsonic, sonic, and ultrasonic activation and preheating of the irrigant.…”
