Taurodontism is a morphologic change characterized by wide pulp chambers, displaced toward the apical floor of the tooth and short roots.
To describe the characteristics of multiple bilateral taurodontism in a female patient.
A 13-year-old female patient evaluated for ectopic eruption of the lower right canine. Physical examination revealed no alteration or apparent mental retardation. Intraoral exam detected multiple carious lesions. Periapical and panoramic X-rays revealed short roots and wide and elongated pulp chambers in the second upper and lower molars. Taurodontism was determined in 2, 15, 18, and 31.
Findings emphasize the importance of radiographic assessment for diagnosing taurodontism, which might present unusual characteristics, such as multiple and bilateral appearance. The absence of a syndrome should not be used to rule out the possible manifestation of this morphologic variation.
尖牙型是一种形态学变化,其特征为宽大的牙髓腔,向牙根尖地板方向移位,以及短根。
描述一名女性患者的多发双侧尖牙型特征。
一名 13 岁女性患者因右下尖牙异位萌出就诊。体格检查未见异常,也无明显智力迟钝。口腔内检查发现多处龋齿。根尖片和全景片显示第二上下磨牙的根短,牙髓腔宽大且拉长。2、15、18 和 31 号牙诊断为尖牙型。
这些发现强调了影像学评估对诊断尖牙型的重要性,其可能具有不寻常的特征,如多发和双侧表现。没有综合征不应作为排除这种形态变异表现的依据。
