Prevalence of Taurodontism in Premolars among Patients at a Tertiary Care Institution in Trinidad



Objectives: A study was undertaken to assess the prevalence of taurodontism in premolars in a group of adult dental patients in Trinidad and Tobago since there is no such data available for the region.

Methods: Periapical and orthopantomograms of 1090 randomly selected patients were examined for the presence of an apically displaced pulp chamber without the usual constriction at the cementoenamel junction.

Results: Prevalence of taurodontism in a sample of 1090 patients was 11.28%. Of the 5324 premolars examined, 4.79% were taurodonts. Prevalence of taurodontism was higher in males (6.46%) compared to females (3.66%). A Statistically significant difference (p < 0.0001) was observed in the prevalence of taurodontism in mandibular premolars compared to maxillary premolars (9.07% vs 0.56%).

Conclusion: Prevalence of taurodontism in premolars among Trinidadian patients, as assessed by radiographic study, was 4.79% and it was higher in the males compared to females. Significant differences were also observed between mandibular and maxillary premolars.
