BACKGROUND
The aim of the study is to investigate the prevalence of talon cusps in a sample of Jordanians dental patients and their distribution among different types of teeth.
METHODS
The data were collected from radiographic examination of 3,024 periapical films showing 9,377 teeth from a random sample of 1,660 patients. A tooth was considered having talon cusp if there was a V-shape radiopaque structure superimposed the tooth structure.
RESULTS
Talon cusps were detected in 52 teeth (tooth prevalence = 0.55%). Maxillary canines were the most commonly affected teeth (46% of cases), followed by maxillary lateral incisor teeth (39% of cases) and maxillary central incisors teeth (15% of cases). Teeth with talon cusps were found in 40 subjects (person prevalence = 2.4%). Bilateral talon cusps were seen in 12 patients.
CONCLUSIONS
Attention should be paid to the presence of talon cusp and the treatment problems associated with it.
背景
本研究旨在调查约旦牙科患者样本中尖牙嵴的流行情况及其在不同类型牙齿中的分布。
方法
从随机抽取的 1660 名患者的 3024 张根尖片的放射学检查中收集数据。如果牙齿结构上有 V 形不透射线结构，则认为该牙齿存在尖牙嵴。
结果
在 52 颗牙齿（牙齿患病率=0.55%）中检测到尖牙嵴。上颌尖牙是最常受影响的牙齿（46%的病例），其次是上颌侧切牙（39%的病例）和上颌中切牙（15%的病例）。在 40 名受试者中发现了具有尖牙嵴的牙齿（人群患病率=2.4%）。12 名患者出现双侧尖牙嵴。
结论
应注意尖牙嵴的存在及其相关的治疗问题。
