Ankylosis of deciduous molar associated with other dental anomalies: report of three cases.

Résumé

Aim Report three cases of primary molar ankylosis associated to dental anomalies, such as hypomineralization of tooth enamel, anodontia, supernumerary teeth, taurodontism and conoid teeth. Background Dentoalveolar ankylosis is an anomaly of eruption which results in the abnormal fusion of the alveolar bone with cementum or dentine. It is commonly observed in deciduous molars, and has no defined etiology. Cases Description It was reported three cases of primary molar ankylosis associated to one or more dental anomaly, like hypomineralization of tooth enamel, anodontia, supernumerary teeth, taurodontism and conical teeth. Summary Although ankylosis is a common anomaly observed in pediatric patients, sometimes it is associated with other alterations, such as dental anomalies of number, form and enamel development. Clinical Significance The coexistence of anomalies may enhance unwanted sequels. Therefore, professionals should consider the possibility of the patient in having associated anomalies with tooth ankylosis, and thus offer adequate treatments and follow-up.
