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.
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.
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%).
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.
由于特立尼达和多巴哥地区尚无此类数据，因此开展了一项研究，以评估一组成年牙科患者前磨牙牛牙症的患病率。
对1090名随机选择的患者的根尖片和全景片进行检查，以确定是否存在根尖移位的牙髓腔，且在牙骨质釉质界处无通常的缩窄。
1090名患者样本中牛牙症的患病率为11.28%。在检查的5324颗前磨牙中，4.79%为牛牙症。男性牛牙症患病率（6.46%）高于女性（3.66%）。与上颌前磨牙相比，下颌前磨牙牛牙症患病率存在统计学显著差异（p < 0.0001）（9.07%对0.56%）。
通过影像学研究评估，特立尼达患者前磨牙牛牙症患病率为4.79%，男性患病率高于女性。下颌和上颌前磨牙之间也观察到显著差异。
