摘要
材料和方法这项以登记为基础的回顾性研究的横断面部分主要针对1315名8-5-10.5岁儿童的牙科全景断层扫描(DPT)。结果DAP儿童的犬齿更常显示出早期治疗的证据(p = 0.014),其中女孩更常接受阻生治疗(p = 0.004),男孩更常接受早期头套治疗(p = 0.022)。牙龄延迟与早期治疗有关(OR 3.29,95% CI 1.08-9.99)。在牙龄不足期的儿童中,犬齿与侧切牙没有重叠或明显重叠的情况更常见,而犬齿的倾斜度在各组之间没有差异。结论牙齿发育异常儿童的犬齿多显示出早期治疗的迹象。在第一个混合阶段之后对犬齿萌出进行监测对于及时进行早期治疗非常重要。
Radiological features and treatment of erupting maxillary canines in relation to the occurrence of dental developmental abnormalities.
OBJECTIVE
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).
MATERIAL AND METHODS
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.
RESULTS
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.
CONCLUSIONS
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.
