Vol. 12 – Number 47 – 2021 NOTEBOOK OF CLINICAL DENTISTRY Case report Page 76-83 Taurodontism – series of case reports in non-syndromic and syndromic young patients associated to hypodontia Renato Barcellos Rédua¹ Giuliane Ribeiro Viana² Maryana Heinze Sechim³ Abstract Several human dentition developmental anomalies are reported in the literature. The etiology of these occurrences is related to genetic, environmental or sometimes idiopathic factors. Taurodontism is defined as apical displacement of the pulp floor and consequent enlargement of the pulp chamber in multiradicular teeth. It is a result of the failure to invaginate Hertwigs epithelial sheath horizontally and commonly expresses bilaterally. This morphological pattern of molars is observed in ruminant animals and was also found in ancient Neanderthals. Association of this condition to syndromes is not exclusive, it may be associated with genetic disorders such as Down Syndrome, Klinefelter Syndrome, among others. The diagnosis is exclusively radiographic, with no alterations in the dental element crown. Among the consequences is the complexity of endodontic treatment, greater fragility of taurodontic teeth submitted to endodontics and lower orthodontic anchorage of these elements. In this paper, three case reports of patients with taurodontism are described, two of them associated with hypodontia and one in a Down Syndrome patient. This paper also includes a literature review and discussion with the main clinical implications of this occurrence.
