BACKGROUNDMost cases of tooth agenesis are presented in the form of hypodontia with different patterns of missing teeth. In addition, there is a frequent clinical association between tooth agenesis and other anomalies.OBJECTIVETo systematically analyze the literature on the prevalence of agenesis of permanent teeth associated with other dental anomalies in nonsyndromic patients.MATERIAL AND METHODSAn electronic search was performed in seven primary databases (Embase, LILACS, BBO, MedLine via PubMed, SciELO, Scopus, and Web of Science) and two additional ones (OATD, and ProQuest) to partially capture the "gray literature." The PECO strategy was used to identify observational studies evaluating the prevalence of agenesis of permanent teeth associated with other dental anomalies in nonsyndromic patients, without restrictions on publication language or year. Two reviewers extracted the data and assessed the individual risk of bias of the eligible studies using the JBI Critical Appraisal Tools for use in JBI Systematic Reviews - Checklist for Cross-sectional, Case-Control, and Cohort Studies.RESULTSThe electronic search revealed 8659 records, seven of which met the eligibility criteria, and were included in the qualitative synthesis. The studies were published from 1961 to 2024. Patients with agenesis were more likely to present taurodontism, microdontia, enamel hypoplasia and distoangulation of the second premolar. Ectopic eruption, infraocclusion of the first deciduous molar and impacted tooth showed mixed results among the eligible studies.CONCLUSIONBased on limited evidence, tooth agenesis was positively associated with the prevalence of other concomitant tooth agenesis.

Advanced Endodontic Techniques for Treating Root Perforation in a Hypertaurodont Molar: A Case Report.

Article

Author: Chamani, Ali ; Zarei, Mina ; Soltaninezhad, Pouria ; Forghani, Maryam

Taurodontism is a dental anomaly characterized by an enlarged pulp chamber and apically displaced pulpal floor. This disorder poses significant challenges in endodontic treatment, especially when perforations occur. The present case study details the endodontic retreatment of a hypertaurodont maxillary second molar in a 36-year-old female patient with a mesial canal perforation. The procedure employed a dental operating microscope for enhanced visualization and precision. Canals were prepared using a crown-down technique, with the perforation site managed using MTA and bioceramic material applied via the second mesiobuccal canal. The remaining canals were obturated using gutta-percha and bioceramic sealer. At the 1-year follow-up, the tooth was functional and asymptomatic, with radiographic evidence of a normal periodontal ligament space. This case demonstrates the efficacy of contemporary endodontic techniques, including bioceramic materials and advanced magnification, in managing the unique challenges posed by taurodontism.

Endodontic Management of Hypertaurodontic Teeth: A Report of Three Cases.

Author: Chamani, Ali ; Zarei, Mina ; Soltaninezhad, Pouria ; Jamali, Seyyedeh Zahra ; Sadeghnezhad, Pegah

Taurodontism is a dental anomaly characterized by the absence of cervical constriction at the cemento-enamel junction, apical shifting of the pulpal floor, and an expanded pulp chamber. 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.
