To investigate the distribution of individual tooth impaction in general dental patients of Northern India.
Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi.
Hospital based crossectional study.
General dental patients were examined clinically and impacted teeth were diagnosed from radiographs. The distribution of impacted teeth (excluding third molars) with respect to the arch, side and gender were recorded. The results were analyzed with respect to the prevalence of individual tooth impaction. The distribution of teeth impaction was evaluated by using the Chi-square test. A p-value of < 0.05 was considered as statistically significant.
Of 27,529 general dental patients examined, 134 (0.49%) had at least one-impacted tooth and a total of 220 impacted teeth were recorded. The most frequently impacted teeth were maxillary canines (52.27%) and the least frequently impacted teeth were maxillary first and second molars (0%).
The prevalence of teeth impaction in the North Indian dental patients was less when compared with the other populations. The most frequently impacted teeth were maxillary canines and the least frequently impacted teeth were maxillary first and second molars.
调查印度北部普通牙科患者中个别牙齿阻生的分布情况。
新德里全印度医学科学研究所牙科教育与研究中心。
基于医院的横断面研究。
对普通牙科患者进行临床检查，并通过X光片诊断阻生牙。记录阻生牙（不包括第三磨牙）在牙弓、侧别和性别的分布情况。根据个别牙齿阻生的患病率对结果进行分析。使用卡方检验评估牙齿阻生的分布情况。p值<0.05被认为具有统计学意义。
在检查的27529名普通牙科患者中，134名（0.49%）至少有一颗阻生牙，共记录到220颗阻生牙。最常发生阻生的牙齿是上颌尖牙（52.27%），最不常发生阻生的牙齿是上颌第一和第二磨牙（0%）。
与其他人群相比，印度北部牙科患者中牙齿阻生的患病率较低。最常发生阻生的牙齿是上颌尖牙，最不常发生阻生的牙齿是上颌第一和第二磨牙。
