An assessment of the association of taurodontism with various dental anomalies, syndromes, systemic diseases and/or genetic diseases, and its role in identification

The aims of the study are to determine the association of taurodontism with numerical, dimensional, formal and structural dental anomalies, various syndromes, systemic diseases and/or genetic diseases, and to represent the clinical implications of the anomaly for clinicians and future forensic and genetic studies. The records of patients examined at the Department of Pedodontics, Faculty of Dentistry, Suleyman Demirel University were retrospectively analysed. A final sample of 837 patients with various dental anomalies, syndromes, systemic and/or genetic disorders was selected and evaluated to detect the presence of taurodontism. A chi-square goodness of fit test was performed to assess the distribution of this anomaly according to gender and localization. Further, Pearson’s correlation coefficient was calculated. Taurodontism was detected in 199 patients. It was mostly encountered with tooth agenesis. The differences of the distribution of this anomaly between the upper/lower jaws were statistically significant. Bilateral taurodontism was more frequent than unilateral taurodontism and was mainly seen on the maxillary first molars. No statistically significant correlation was found between the missing and taurodont teeth. Identifying individuals with multiple dental anomalies and/or with the syndromes and systemic diseases could serve as a guide for further forensic and genetic studies.

An extremely rare case of bilateral taurodontism in mandibular molars with bilateral pyramidal maxillary first molars: A case report of a rare morphology

Endodontic treatment can only be successfully achieved with the adequate knowledge of root canal morphology and its variations. In this case report, intraoral periapical radiograph revealed single-root with centrally located single canal bilaterally in the maxillary first molar and bilateral taurodontism in both the first and second molar which is the most rear of the rear. To the best of our knowledge, this is a very rare case reported of both bilateral taurodontism and pyramidal teeth in the primary dentition in the literature.

Bilateral taurodontism in primary and permanent molars associated with hypodontia

The article is to present a case of bilateral taurodontism in primary and permanent molars associated with hypodontia and to discuss the endodontic aspects. Taurodontism in permanent molars are most commonly affected and it has a very low incidence, and very fewer cases are reported in the literature in the deciduous dentition. A 12-year-old boy presented with irregularly placed tooth in upper right back region of the jaw. Orthopantomogramrevealed taurodontism in seven teeth including both primary and permanent teeth, associated with congenitally missing three premolars and permanent mandibular central incisors. Taurodontism is more frequent in nonsyndromic familial tooth agenesis. Individuals in families with second premolar and molar oligodontia are more likely to have taurodontism. Since there is a wide variation in size and shape of pulp chamber with varying degree of obliteration and canal configuration, root canal therapy becomes a challenge so it is essential to recognize and render preventive care for these teeth.

Prevalence of taurodontism among the patients visiting a dental teaching hospital in Pune, India: A retrospective orthopantomogram study

Introduction: Taurodontism is a morpho-anatomic variation in the shape of teeth that chiefly affects molars in primary as well as secondary dentition. Aim: The aim was to assess the prevalence of taurodontism in premolars and molars by studying the orthopantomogram (OPGs) of the patients visiting a dental teaching hospital in Pune, India. Materials and Methods: A retrospective, cross-sectional study was carried out, wherein the panoramic radiographs of 525 randomly selected patients were evaluated for taurodontism. A detailed medical and family history record of the patients was also obtained. Radiographic analysis for taurodontism was carried out in premolars and molars. Prevalence of taurodontism was assessed, and a comparison among male and female prevalence was done using the z -test. Results: Prevalence of taurodontism was 11.8%. Taurodontism was exhibited in 12.5% females and 9.7% males. Unilateral taurodontism was seen in 24 (4.57%) and bilateral taurodontism in 38 (7.23%) of the 525 OPGs. Mandibular second molars were the teeth most commonly affected by taurodontism. Conclusion: There was a high prevalence of taurodontism in patients visiting the dental teaching institute. Orthopantamogram can be used effectively to detect taurodontism. The findings of this study revealed that premolars may also be affected with taurodontism.

Bilateral taurodontism in primary and permanent molars associated with hypodontia

The aim of this article is to present a case of bilateral taurodontism in the primary and permanent molars associated with hypodontia and to discuss the endodontic aspects. Taurodontism in the permanent molars are most commonly affected, and it has a very low incidence and very few cases are reported in the literature in deciduous dentition. A 12-year-old boy presented with irregularly placed tooth in the upper right back region of his jaw. Orthopantamogram revealed taurodontism in seven teeth, including both primary and permanent teeth, associated with congenitally missing three premolars and permanent mandibular central incisors. Taurodontism is more frequent in non-syndromic familial tooth agenesis. Individuals in families with second premolar and molar oligodontia are more likely to have taurodontism. Because there is a wide variation in size and shape of pulp chamber with a varying degree of obliteration and canal configuration, root canal therapy becomes a challenge and, therefore, it is essential to recognize and render preventive care for these teeth.

Endodontic treatment of hypertaurodontism with multiple bilateral taurodontism

The term taurodontism is derived from the Latin word tauros, for “bull,” and the Greek term odus, for “tooth,” or “bull tooth.” Taurodontism is a morpho-anatomical developmental anomaly, which is seen infrequently in teeth only. It is characterized by a deficiency in the constriction at the cement-enamel junction, with lengthened pulp chambers and apical displacement of the pulpal floor. This gives the tooth a quadrilateral or cylindrical look. This report presents a case of multiple bilateral taurodontism and the successful endodontic treatment of the tooth that had hypertaurodontism. A male patient was referred to the endodontic clinic with decayed left maxillary first molar. Hypertaurodontism was confirmed after clinical and radiographic examination. Panaromic X-rays revealed that all of the patient's molar teeth were taurodontic. Taurodontism offers challenges to the practitioner during shaping and disinfection and at the time of filling the root canals.

Multiple Bilateral Taurodontism. A Case Report

Introduction Taurodontism is a morphologic change characterized by wide pulp chambers, displaced toward the apical floor of the tooth and short roots. Objective To describe the characteristics of multiple bilateral taurodontism in a female patient. Case Report A 13-year-old female patient evaluated for ectopic eruption of the lower right canine. Physical examination revealed no alteration or apparent mental retardation. Intraoral exam detected multiple carious lesions. Periapical and panoramic X-rays revealed short roots and wide and elongated pulp chambers in the second upper and lower molars. Taurodontism was determined in 2, 15, 18, and 31. Conclusion Findings emphasize the importance of radiographic assessment for diagnosing taurodontism, which might present unusual characteristics, such as multiple and bilateral appearance. The absence of a syndrome should not be used to rule out the possible manifestation of this morphologic variation.

Orodental findings of a family with lacrimo-auriculo-dento digital (LADD) syndrome

Lacrimo-auriculo-dento-digital (LADD) syndrome is an autosomal dominantly inherited disorder characterized mainly by hypoplasia/aplasia of lacrimal and salivary tracts, small cup-shaped and/or malformed ears, sensorineuronal or conductive hearing loss, abnormalities of the teeth, and variable anomalies of the hands and feet. In this case report, general and dentofacial features of 2 siblings and their father are described. Both siblings presented hypoplastic lacrimal puncta, cup-shaped/low-set ears with bilateral sensorineuronal hearing loss, broad first toes, and bilateral clinodactyly of the fifth toes. The 17-year-old female revealed mainly peg-shaped incisors, long thin-rooted teeth, malformed molars, microdontia, and enamel hypoplasia; and the 10-year-old male showed a short lingual frenulum, peg-shaped incisors, shallow cusps, agenesis of mandibular second premolars, and taurodontism. Father exhibited hypoplastic puncta, hypolacrimia, mild bilateral sensorineural hearing loss, taurodontism, and absence of some teeth. In conclusion, this case report of a family has demonstrated the various general and orofacial features encountered in LADD syndrome.
