目的:本研究的目的是评估与没有颅面疾病的对照组相比,德国非综合征性唇裂和/或腭裂和Robin裂的正畸患者的牙齿发育不全。
方法:使用牙齿机构代码(TAC)的二元系统(不包括第三磨牙)检查了总共108张全景X射线照片。将患者分为颅面障碍1组(n=43)和健康对照组2(n=65)。参数,如骨骼类畸形,性别,裂口的定位,颅面疾病,和观察者间的可靠性进行了评估。
结果:在第1组中观察到44%的永久性牙齿发育不全,在第2组中观察到14%的永久性牙齿发育不全,具有统计学上的显着较高患病率(p=0.00162(χ2))。在第1组中观察到14种不同的TAC模式,其中10种在单独的患者中仅发生一次。第2组中TAC代码的分布显示了TAC代码模式的9种不同可能性;七个TAC是唯一的。在第1组中,最常见的缺牙是左侧的上颌侧切牙(30%);在第2组中,右侧的下颌第二前磨牙(9%)。男性颅面疾病患者的牙齿发育不全比例高于女性。
结论:此处提供的数据显示,德国非综合征性颅面部疾病患者的牙齿发育不全患病率具有统计学意义。
结论:射线照相评估可以诊断牙齿发育不全。在开发长期和全面的跨学科治疗时,尽早认识到显示颅面疾病的患者牙齿发育不全的患病率较高是一个重要问题。
OBJECTIVE: The study objective was to evaluate the tooth agenesis in German orthodontic patients with non-syndromic cleft lip and/or palate and Robin sequence compared to a control group without craniofacial disorder.
METHODS: A total of 108 panoramic radiographs were examined using the binary system of Tooth Agenesis Code (TAC) (excluding the third molar). Patients were divided into the craniofacial disorder group 1 (n = 43) and the healthy control group 2 (n = 65). Parameters such as skeletal class malformation, sex, localization of the cleft, craniofacial disorder, and interobserver reliability were assessed.
RESULTS: Permanent tooth agenesis was observed in 44% of group 1 and 14% in group 2 with a statistically significant higher prevalence (p = 0.00162 (χ2)). Fourteen different TAC patterns were observed in group 1, ten of these occurring only once in separate patients. The distribution of the TAC codes in group 2 showed nine different possibilities of TAC code patterns; seven TACs were unique. In group 1, the most frequently absent teeth were the maxillary lateral incisor of the left side (30%); in group 2, the second premolar of the lower jaw on the right side (9%). Male patients with craniofacial disorder showed a higher percentage of tooth agenesis than female.
CONCLUSIONS: The data presented here shows a statistically significant higher prevalence of tooth agenesis in German patients with non-syndromic craniofacial disorder.
CONCLUSIONS: Radiographic evaluation enables the diagnosis of tooth agenesis. Recognizing early on the higher prevalence of tooth agenesis in patients exhibiting a craniofacial disorder is an important issue when developing long-term and comprehensive interdisciplinary treatment.
