The presence of two roots with separate canals, as defined by Vertucci's type V morphology, is extremely rare and presents diagnostic and technical challenges for nonsurgical endodontic treatment. This report describes the endodontic management of a maxillary right central incisor (tooth #11) exhibiting a sinus tract, negative responses to pulp sensibility tests, and radiographic evidence of apical periodontitis in a 24-year-old female patient. Cone-beam computed tomography (CBCT) revealed a two-rooted anatomy with independent canals splitting at the middle third. Under magnification, access was refined using ultrasonic tips. The palatal root canal was prepared with NiTi CM rotary files, while the wider buccal canal was instrumented with stainless steel K-files. Both canals were disinfected using passive ultrasonic irrigation with 2.5% sodium hypochlorite and 17% EDTA, followed by intracanal calcium hydroxide medication. Obturation was completed using the single-cone technique with a bioceramic sealer. Radiographic follow-up at 14 and 57 months confirmed complete periapical healing and absence of symptoms, demonstrating long-term clinical success. Atypical root canal anatomy in maxillary incisors necessitates advanced imaging/magnification. The use of CBCT, NiTi CM files, and bioceramic sealers enabled accurate diagnosis, conservative canal shaping, and a successful long-term outcome in this rare morphology case.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"21 1","pages":"e6"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12900521/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146201686","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}

Such diagnostic discrepancies highlight the limitations of conventional pulp testing and may create opportunities for biologically based treatment approaches. This case report describes the successful management of a mature permanent molar initially diagnosed as necrotic but found intraoperatively to contain vital radicular pulp tissue. A 36-year-old healthy patient presented with pain on chewing and tenderness to percussion in the left mandibular second molar. Clinical and radiographic examination revealed severe coronal destruction, a periapical radiolucency, and a negative response to cold testing, leading to a preoperative diagnosis of pulp necrosis with apical periodontitis and a treatment plan for root canal therapy. However, during access cavity preparation, profuse bright-red bleeding from the canal orifices indicated retained vital radicular pulp tissue. Consequently, treatment was changed to full pulpotomy. Because hemostasis could not be achieved after 5 minutes using 2.5% sodium hypochlorite-soaked cotton pellets, a tampon technique was performed with calcium-enriched mixture cement placed over the radicular pulp stumps, followed by definitive restoration. The patient became symptom-free within one week and remained asymptomatic throughout the 4-year follow-up period. Radiographic examination demonstrated complete resolution of the periapical lesion, re-establishment of the lamina dura, and normalization of the periodontal ligament space. This case demonstrates that teeth initially diagnosed as necrotic may still harbor maintainable vital radicular pulp tissue. Careful intraoperative assessment can alter both diagnosis and treatment strategy. Full pulpotomy using an endodontic biomaterial and a tampon technique resulted in complete clinical and radiographic healing over four years.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"21 1","pages":"e22"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13332818/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148390986","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 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}

Anatomical variations in mandibular second premolars are uncommon compared to other teeth, and the coexistence of a C-shaped root canal configuration with four independent canals and four separate apical foramina is exceptionally rare. This case report describes the nonsurgical endodontic management of a mandibular second premolar exhibiting this unique morphology, confirmed through cone-beam computed tomography (CBCT) and magnification. A 52-year-old male was referred by a prosthodontist for elective root canal treatment before post placement. CBCT imaging revealed a C-shaped root in the coronal third that bifurcated into four separate canals at the midroot level, each terminating in an independent apical foramen. Nonsurgical treatment was performed over two visits, using meticulous chemo-mechanical preparation, intracanal calcium hydroxide dressing, and warm vertical compaction obturation. At the 9-month follow-up, the tooth was functional, asymptomatic, and radiographically stable.

This classification indicates an increased likelihood of procedural errors. However, advancements in dental technology have simplified the endodontic treatment of calcified teeth. Guided endodontics uses cone-beam computed tomography (CBCT) and a three-dimensional (3D) printer to create a patient-specific guide, enhancing accuracy and predictability in complex cases. A healthy 60-year-old male was referred by a prosthodontist for root canal treatment on teeth #23, #24, and #25. Periapical radiographic examination revealed partial PCO in all teeth. After choosing guided endodontics treatment, CBCT imaging and intraoral 3D scanning were utilized to design a patient-specific endodontic guide. After verifying the stability of the endo-guide, access cavities were prepared using a Munce Discovery bur. Following the negotiation of the canals, the working length was determined. Root canal treatment was performed using rotary files up to size 25/0.04% and sodium hypochlorite irrigation. The obturation was completed using the warm condensation technique. Although PCO was present, no complications occurred during treatment. The teeth remained completely asymptomatic and functional, demonstrating the success of the treatment. Guided endodontics can be a practical and predictable approach for managing PCO in mandibular incisors. This technique provides accurate canal location, reduces procedural errors, and preserves tooth structure. Despite concerns about cost, radiation exposure, and challenges with anatomical variations, it represents a promising advancement in endodontic treatment.","PeriodicalId":14534,"journal":{"name":"Iranian Endodontic Journal","volume":"20 1","pages":"e21"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12318319/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144775399","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}

Based on the evaluated studies, probably the most significant advancement of dental lasers is in optimizing the treatment outcome of root canal therapy via enhanced disinfection of root canals. Moreover, various research has shown that dental lasers can also aid in diagnosing vitality of pulp, vital pulp therapy, apiectomy, regenerative treatments, pain management treatment after root canal therapy, access cavity preparation, sterilization and irrigation of root canals, treatment of periapical lesions, removing excess materials and broken instruments in canals, and prompting the healing process after root canal therapy. As evidenced by the obtained results, diode and erbium lasers have the most applications in endodontics with the lowest side effects. Nonetheless, all dental lasers face multiple limitations, including producing noticeable thermal changes and smoke and damaging surrounding structures at the emission site, which question their safe usage in clinical practice.
