Abstract
INTRODUCTION: Dental anomaly patterns (DAP) are associated dental abnormalities that are observed together much more frequently than con be explained by chance alone. The inclusion of taurodontism within the group of DAP has been met with controversy. OBJECTIVE: To investigate the association between hypodontia and taurodontism to support its possible inclusion in the DAP. METHODS: Presence of taurodontism of tooth 36 was analyzed in OPGs performed in 100 patients with hypodontia and 100 control subjects obtained from the database of the Orthodontics Unit of Fundación Jiménez Díaz Hospital (Madrid]. To define taurodontism a visual method was used, consisting of a chart comparison with 4 images depicting normal pulp chamber, hypotaurodontism, and moderate and severe taurodontism. Possible association between taurodontism and agenesia was assessed by means of Fisher's exact test. RESULTS. 9% of patient with hypodontia and only 3% of control cases revealed pulp sizes that were consistent with the visual diagnosis of taurodontism. This difference did not reach statistical significance. CONCLUSION. Although the presence of taurodontism was higher among the patients with hypodontia than in controls, the differences observed did not permit the unquestionable inclusion of this anomaly in the DAP. Further studies are required to clarify this possible association.
