[Changes in the dental hard tissues and supporting structures in tetanic syndrome. I. Review of the literature].

The authors give a survey of the literature on the tetanic syndrome and its effects on the dental hard tissues and the tooth supporting structures. In cases of normocalcaemic tetany, no pathological alterations have been observed in the dental hard tissues, the pulp and the periodontium. On the contrary, enamel hypoplasia, broad pulp chambers, shortened tooth rootsdelayed dentition, hypodontia, inflammatory changes and bleedings from the periodontal ligament, bone densification and chronic gingivitis have been found in patients with hypocalcaemic tetany.
