Upon endodontic access, a vertical crack extending into the mesial canal walls was observed. Root canals were identified and shaped using rotary instruments. Calcium hydroxide was placed as an intracanal dressing. After one week, the patient returned without inflammatory signs. The root canals were filled with gutta-percha and bioceramic cement. Biodentine repair cement was applied 2.0 mm beyond the orifice to seal and reinforce the area. The endodontic access cavity was restored with composite resin. Clinical and radiographic follow-ups at 12 months revealed significant periapical healing and the absence of inflammatory signs. A radiographic and computed tomography scan at 48 months confirmed substantial bone repair and continued tooth functionality. The intraorifice barrier with Biodentine demonstrated notable effectiveness, aligning with literature on its benefits. The protocol, integrating modern techniques and timely restoration, shows promise in managing cracked teeth with root extension, enhancing tooth preservation in complex cases.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e27"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12318318/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144775383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inclusion criteria consisted of all in vitro studies up to October 2024 that documented the application of cone-beam computed tomography in creating a guide for endodontic retreatment cases. The reviewers assessed the quality of the selected studies using the QUIN tool. Data regarding the first author and publication year, sample size, tooth type, retreatment application, computer-aided navigation technique, groups, image acquisition method, outcome measures, guided technique results, conventional technique results, and the main results were extracted using a predefined template.Results: Based on our criteria, seven studies were included in this review. The studies demonstrated variability in the techniques utilized. Iatrogenic errors were less frequent in guided groups, regardless of the operator's level of experience. Most studies indicated that guided endodontics was more effective than conventional methods, particularly in fiber post-removal and access through MTA, minimizing volumetric loss of tooth structure, and preserving fracture resistance. However, when using guided techniques for removal of separated instruments, more iatrogenic errors occurred, and more time was required compared to the freehand technique.Conclusion: Guided endodontics has shown promise in improving the outcomes of non-surgical retreatment by reducing complications. However, as all included studies were in vitro, clinical evidence is lacking, and the generalization of these results should be done cautiously. Further well-designed clinical studies are required to confirm these findings.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e3"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808322/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This condition presents unique challenges in endodontic diagnosis and treatment due to its variable morphology, deeply located orifices, and complex root canal system. This paper reports three cases of hypertaurodontism (Taurodont Index ≈ 50), including a maxillary first molar, mandibular third molar, and mandibular second premolar in systemically healthy patients. The identification and treatment planning were facilitated by cone-beam computed tomography (CBCT). Root canal therapy was performed under a dental operating microscope, with careful exploration, chemomechanical instrumentation using rotary files, copious irrigation with 5.25% sodium hypochlorite, and warm vertical obturation. Twelve months later, follow-up visits showed that all patients were clinically and radiographically asymptomatic, indicating successful outcomes. Taurodontism presents significant challenges due to its anatomical complexities. A multifaceted approach involving CBCT, dental operating microscopes, ultrasonic irrigation, and warm vertical obturation is recommended. This case series demonstrates that with advanced diagnostic aids and meticulous techniques, even hypertaurodontic teeth can be effectively managed.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e12"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11980998/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This report highlights 14 diverse cases where bio-obturation was employed to manage complications such as internal and external resorption, root perforations, draining sinus tracts, mechanical obstructions, and trauma-related injuries. The outcomes demonstrate notable healing and resolution of various tooth related pathologies in failed primary root canal treatments. Root perforations and canal blockages were successfully sealed, restoring the integrity of the root canal system and ensuring continued tooth function and retention. Bio-obturation facilitated stabilization and regeneration of periradicular and supporting tissues in trauma cases, including avulsed teeth and inflammatory root resorption. Cases involving open apices, dens invaginatus, and complex root canal anatomy also showed favorable results. Overall, bio-obturation offers a transformative alternative to conventional root canal filling by promoting enhanced biological sealing and improved periradicular healing, thus increasing the probability of sustainable long-term clinical success. While calcium-enriched mixture cement served as the bioactive material in these cases, this approach may also be effectively implemented using other advanced calcium silicate-based biomaterials, broadening its applicability in challenging endodontic scenarios.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e15"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11980999/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144009599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study describes three cases in which contemporary restorative techniques were employed and suggests that applying Ribbond tape (RT) to ETT can improve fracture resistance and better prevent the propagation of cracks compared with traditional methods. Although extensive in vitro research has been conducted on fiber-reinforced composites, studies evaluating the clinical use and durability of fiber-reinforced composites to restore ETT are limited. This report strictly adhered to the case report (CARE) guidelines, and the treatments were initiated only after signed informed consents were obtained from the patients. Therefore, the old restorations were removed from the teeth that required intervention and composite resin core build-up was created, followed by endodontic treatments or retreatment. Subsequently, the endodontic accesses were reinforced with RT. The protective restorations were performed and bonded. The two-year follow-ups showed that the patients had complete remission of signs and symptoms, and they remain under monitoring. The study emphasizes the importance of internal reinforcement of ETT and strengthening weakened walls with a resin core build-up reinforced with fibers like RT. This approach enhances mechanical retention, inhibit fracture propagation, and establish a strong chemical bond between RT and resin. It is suggested to be a promising strategy for increasing the longevity and strength of the teeth, providing a conservative and effective alternative to traditional methods.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e13"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11980996/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144001148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The extraoral examination revealed atypical anatomy, while vitality and percussion tests were negative, palpation test was positive. Edema was observed in the adjacent gingival mucosa. Based on clinical and tomographic findings, the diagnosis was pulp necrosis with chronic periapical abscess and Oehlers' type II dens invaginatus. In the first session, access surgery was performed with spherical drills with the aid of an operating microscope (OM) and an ultrasonic diamond tip. Four canals were located, and they were partially debrided and medicated. In the second session, odontometry and chemical-mechanical preparation with nickel-titanium instruments were performed. The irrigation solution was 2.5% sodium hypochlorite. The root canals were filled with calcium hydroxide paste and the chamber was temporarily sealed. During the third session, ultrasonic irrigation was applied for final washing and the root canals were filled with Bio-C sealer using the classic single-cone technique. At 6-month follow-up, the tooth was asymptomatic and the radiography revealed significant bone repair. It was concluded that tomography, operating microscope, ultrasonic irrigation, and materials with greater flow, such as bioceramic sealers, enhanced the clinical success of the clinical case.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e7"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808323/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
