This PubMed-based review comprehensively evaluates seven distinct VPT techniques; including their historical development, broad definitions, clinical protocols and treatment outcomes as evidenced by systematic reviews and meta-analyses. The VPT modalities covered in this review include stepwise excavation, indirect pulp capping, direct pulp capping, miniature pulpotomy, partial pulpotomy, full pulpotomy and partial pulpectomy. Stepwise excavation, as a minimally-invasive option, has demonstrated effectiveness in reducing the risk of pulp exposure, particularly in permanent teeth. Clinical outcomes of indirect and direct pulp capping are promising; specifically with the application of advanced calcium silicate cements. Miniature and partial pulpotomies emphasize the importance of precise definitions and standardised protocols due to their subtle differences. Full pulpotomy has emerged as a viable alternative to root canal treatment, achieving comparable success rates in managing irreversible pulpitis. While partial pulpectomy remains the most invasive approach, it has shown potential in managing complex cases, such as root resorption, through selective tissue preservation. Despite advancements in biomaterials and technique standardisation, challenges remain, including variability in clinical protocols, limited high-quality evidence, and the need for long-term studies to better evaluate anticipated outcomes. Nevertheless, emerging biotechnologies hold promise for enhancing the precision and predictability of VPT procedures in the future.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e2"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399212","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 sensory loss may be the result of a reversible and/or irreversible nerve damage, and it can be caused by local or systemic factors. Local factors include traumatic injuries caused by impacted teeth, local injection, endodontic therapy, implant placement and exposure to toxic materials. This article reports a paresthesia by anesthetic injection. A 44-year-old man reported moderate pain during chewing and exposure to cold. Upon clinical examination, extension of the tooth fracture line was in the mesiodistal region of the mandibular left second premolar crown and was detected with 16× magnification of microscope. The diagnosis was cracked tooth syndrome, and root canal treatment was indicated. After the first appointment the patient reported altered sensation on left side of mandible, numbness and electric shock sensation, and therefore was diagnosed with mental nerve paresthesia. Diclofenac sodium, thiamine, cyanocobalamin, and pyridoxine were prescribed for 7 days as part of the treatment, and then root canal and restorative treatments were completed. Patient was scheduled for follow-up appointments after 1, 3, 6, and 8 months. After the first month, the feeling of paresthesia was still present and the patient was experiencing a painful \"electric shock\". At the 8-month follow-up visit, the paresthesia had been resolved with return of normal sensation.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e5"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11808329/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399195","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}
