The aim of the present study was to present detailed information regarding the impacted maxillary and mandibular canines and their patterns of presentation into the oral cavity and to evaluate the prevalence of different canine anomalies, such as ectopic canine, transmigration, transposition and agenesis of permanent canines among central Indian population.
A total of 1593 patients OPG's were thoroughly evaluated and the prevalence of different canine anomalies like impacted maxillary and mandibular canine, transmigration, transposition, agenesis and ectopic canine eruptions were evaluated. The canine angulation, vertical position in relation to occlusal surface of adjacent tooth's and the overlapping of adjacent teeth's crown by impacted canine was evaluated by tracings.
Out of 1593 subjects, 22 patients had impacted canines. The prevalence of canine impaction was1.38%, with maxillary canine impaction of 0.93%, mandibular canine impaction of 0.37%, canine agenesis 0.06%, transmigration 0.12%, canine transposition 0.18% and the ectopic canine was 5.5%.
There is no gender difference in canine impaction. The prevalence of canine impaction is 1.38%.
本研究的目的是提供有关上颌和下颌阻生尖牙及其进入口腔的表现模式的详细信息,并评估印度中部人群中不同尖牙异常的患病率,如异位尖牙、移位、易位和恒牙尖牙先天缺失。
对总共1593例患者的口腔全景片进行了全面评估,并评估了不同尖牙异常的患病率,如上颌和下颌阻生尖牙、移位、易位、先天缺失和异位尖牙萌出。通过描图评估尖牙的角度、相对于相邻牙齿咬合面的垂直位置以及阻生尖牙对相邻牙齿牙冠的重叠情况。
在1593名受试者中,有22例患者存在阻生尖牙。尖牙阻生的患病率为1.38%,其中上颌尖牙阻生率为0.93%,下颌尖牙阻生率为0.37%,尖牙先天缺失率为0.06%,移位率为0.12%,尖牙易位率为0.18%,异位尖牙率为5.5%。
尖牙阻生不存在性别差异。尖牙阻生的患病率为1.38%。
