This study aimed to investigate the radiological features of the permanent canines and the treatment carried out to ensure their eruption relative to certain features involved in Dental Anomaly Patterns (DAP).
The cross-sectional part of this retrospective register--based study focused on 1,315 dental panoramic tomographs (DPTs) of children aged 8.5-10.5 years, while the longitudinal part involved information on the treatment provided for 1,269 canines after the DPTs and on their eruption into the oral cavity.
The canines of the DAP children more often showed evidence of early treatment (p = 0.014), with girls having more frequently interceptive treatment (p = 0.004) and boys early headgear (p = 0.022). Delayed dental age was associated with early treatment (OR 3.29, 95% CI 1.08-9.99). Either no or clear overlapping of a canine with the lateral incisor occurred more often in the DAP children, whereas canine inclination did not differ between the groups. The root development stage of the canine was more often either beginning or well advanced in the DAP children.
The children with dental developmental abnormalities more often showed evidence of early treatment for the canines. Monitoring of the erupting canines after the first mixed stage is important to enable timely early treatment.
本研究旨在调查恒牙尖牙的放射学特征以及为确保其萌出而进行的治疗，这些治疗与牙列异常模式（DAP）所涉及的某些特征有关。
这项基于回顾性登记的研究的横断面部分聚焦于1315张8.5至10.5岁儿童的牙科全景断层扫描（DPT），而纵向部分涉及DPT之后为1269颗尖牙提供的治疗信息以及它们萌出到口腔中的情况。
DAP儿童的尖牙更常显示早期治疗的迹象（p = 0.014），女孩接受阻断性治疗的频率更高（p = 0.004），男孩使用早期头帽的频率更高（p = 0.022）。牙龄延迟与早期治疗相关（比值比3.29，95%可信区间1.08 - 9.99）。在DAP儿童中，尖牙与侧切牙无重叠或明显重叠的情况更常见，而两组之间尖牙倾斜度无差异。在DAP儿童中，尖牙的牙根发育阶段更常处于开始或进展良好的状态。
患有牙齿发育异常的儿童更常显示出尖牙早期治疗的迹象。在第一恒磨牙萌出阶段之后监测萌出的尖牙对于及时进行早期治疗很重要。
