The study is planned to correlate the existence of dental anomalies with different types of malocclusion as the occurrence of anomalies is common in malocclusion.
The present study was conducted among 430 patients with different types of malocclusion as 161 patients having Class I, 203 with Class II, and 66 with Class III malocclusion. The age of the patients ranged from 12 to 15 years. Diagnosis was done on the basis of history, clinical, cephalometric, radiographs, and dental cast examination. The level of significance was set at P = 0.05.
Most common anomaly was rotation of teeth (18.80%), followed by hypodontia (10.90%), and least occurring was gemination, fusion, talon's cusp, and dilacerations. 31.4% showed one dental anomaly, whereas 11.9% exhibited two or more dental anomalies. The highest mean value of all the dental anomalies was seen with severe cases of malocclusion and also significant differences were observed according to gender.
The present study investigated various dental anomalies in relation to malocclusion. It was found that 31.4% showed one dental anomaly, whereas 11.9% exhibited two or more dental anomalies. Hence, careful prior investigation of dental anomalies is necessary for better orthodontic treatment planning to reduce the complications.
由于牙齿异常在错牙合畸形中很常见，本研究旨在将牙齿异常的存在与不同类型的错牙合畸形相关联。
本研究对430例不同类型错牙合畸形患者进行，其中161例为I类错牙合畸形，203例为II类错牙合畸形，66例为III类错牙合畸形。患者年龄在12至15岁之间。根据病史、临床检查、头影测量、X光片和牙模检查进行诊断。显著性水平设定为P = 0.05。
最常见的异常是牙齿旋转（18.80%），其次是缺牙（10.90%），最少见的是双生牙、融合牙、畸形中央尖和牙折。31.4%的患者有1种牙齿异常，而11.9%的患者有2种或更多种牙齿异常。在严重错牙合畸形病例中，所有牙齿异常的平均数值最高，并且根据性别也观察到了显著差异。
本研究调查了与错牙合畸形相关的各种牙齿异常。发现31.4%的患者有1种牙齿异常，而11.9%的患者有2种或更多种牙齿异常。因此，为了更好地进行正畸治疗计划以减少并发症，有必要在术前仔细检查牙齿异常情况。
