The position of the canine has a key role in facial harmony, dental aesthetics, functional occlusion, and health of temperomandibular joint. Maxillary canine impaction is the second most common tooth after third molars impaction. Maxillary canines are more prone to impaction due to longer path of eruption.
All the patients were examined in the Dental Chair light and referred to the department of Oral Radiology for Orthopantomogram. Yamamoto's classification was used to classify maxillary canine impaction. Position of mandibular canine from cement-enamel junction was used for mandibular canine impaction.
The study was performed on 2300 patients who consulted the orthodontic department from January 2018 to July 2022. Orthopantomogram of each patient was examined for canine impaction, retained deciduous teeth, cyst, and other anomalies. The incidence and pattern of canine impaction was assessed.
The data was then statistically analyzed using Graph Pad Prism software. The incidence of impacted canine was evaluated. The effect of gender was evaluated using a -test.
A total of 2300 subjects were examined out of which 52 individuals were diagnosed with canine impaction. The incidence of canine impaction among orthodontic patients is 2.26%. The amount of canine impaction in females (60%) is higher than males (40%). The ratio of canine impaction of the maxilla and mandible is 2.5.
The incidence of canine impaction was found to be 2.26 percent in the tribal dominant population of Jharkhand. Type II (50%) pattern in the maxilla and Level A (57%) impaction in the mandible was found to be the highest.
犬齿的位置在面部和谐、牙齿美观、功能咬合以及颞下颌关节健康方面起着关键作用。上颌犬齿阻生是继第三磨牙阻生之后第二常见的牙齿阻生情况。由于萌出路径较长,上颌犬齿更易发生阻生。
所有患者均在牙科椅灯光下进行检查,并被转至口腔放射科拍摄全景曲面断层片。采用山本分类法对上颌犬齿阻生进行分类。以下颌犬齿牙骨质-釉质界的位置来判断下颌犬齿阻生情况。
该研究对2018年1月至2022年7月期间到正畸科就诊的2300例患者进行。检查每位患者的全景曲面断层片,以确定是否存在犬齿阻生、乳牙滞留、囊肿及其他异常情况。评估犬齿阻生的发生率和模式。
然后使用Graph Pad Prism软件对数据进行统计分析。评估阻生犬齿的发生率。使用t检验评估性别因素的影响。
共检查了2300名受试者,其中52人被诊断为犬齿阻生。正畸患者中犬齿阻生的发生率为2.26%。女性犬齿阻生的比例(60%)高于男性(40%)。上颌与下颌犬齿阻生的比例为2.5。
在贾坎德邦部落主导人群中,发现犬齿阻生的发生率为2.26%。发现上颌中II型(50%)模式和下颌中A级(57%)阻生最为常见。
