This study aims to estimate the prevalence of congenitally missing lateral incisors in a sample of 2662 dental patients in Palestine.
A total of 2662 digital panoramic radiographs were retrospectively examined for the presence of congenitally missing permanent lateral incisors. The radiographs were obtained from the archival records of patients attending a local dental center at the city of Nablus in Palestine.
The prevalence of missing lateral incisors among the examined population (n = 2662) was found to be 1.91%. Unilateral agenesis accounted for 66.6% of the total cases that showed at least one missing lateral incisor. Around 79% of the unilateral cases were on the left side while 21% were on the right side. Bilateral agenesis accounted for 33.3% of 34 cases that had at least one congenitally missing permanent maxillary lateral incisor.
The prevalence of missing maxillary lateral incisors in this study population was 1.91%) which was within the range reported in different populations.
本研究旨在估计巴勒斯坦2662名牙科患者样本中先天性侧切牙缺失的患病率。
回顾性检查了总共2662张数字化全景X线片，以确定是否存在先天性恒牙侧切牙缺失。这些X线片取自巴勒斯坦纳布卢斯市一家当地牙科中心患者的档案记录。
在所检查的人群（n = 2662）中，侧切牙缺失的患病率为1.91%。单侧发育不全占至少有一颗侧切牙缺失的总病例数的66.6%。约79%的单侧病例发生在左侧，21%发生在右侧。双侧发育不全占34例至少有一颗先天性恒牙上颌侧切牙缺失病例的33.3%。
本研究人群中上颌侧切牙缺失的患病率为1.91%，在不同人群报告的范围内。
