. We quantified the prevalence of impacted maxillary canines (IMC) and their association with other dental anomalies (DAs). . A retrospective study was done with 860 patients 12 to 39 years of age. The prevalence of IMC was calculated and compared by sex. The sample was divided into a control group and an impaction group, and the prevalence was calculated in both for a series of anomalies: agenesis, supernumerary teeth, shape anomalies of the upper laterals (microdontia, peg and barrel shape, and talon cusp), fusion, gemination, other impacted teeth, transposition, and amelogenesis imperfecta. The prevalence values for both groups were compared (Pearson's test, ≤ 0.05). . IMC were present in 6.04% of the sample with no difference by sex ( = 0.540). Other DAs occurred in 51.92% of the IMC group and in 20.17% of the controls ( < 0.05). Significant associations ( < 0.05) were identified between IMC and four other DAs: microdontia, barrel shape, other impacted teeth, and transposition. The prevalence of all anomalies was lower in the control group. . IMC were seen in 6.04% of patients. Patients with this condition also had a higher prevalence of other DAs. These other anomalies should be used as risk indicators for early diagnosis.
我们对埋伏上颌尖牙（IMC）的患病率及其与其他牙齿异常（DA）的关联进行了量化。对860名年龄在12至39岁之间的患者进行了一项回顾性研究。计算了IMC的患病率并按性别进行比较。将样本分为对照组和埋伏组，计算两组中一系列异常情况的患病率：牙胚缺失、多生牙、上颌侧切牙形态异常（过小牙、钉状和桶状以及尖牙）、融合、双生牙、其他埋伏牙、易位和釉质发育不全。比较两组的患病率值（Pearson检验，P≤0.05）。IMC在6.04%的样本中存在，性别间无差异（P = 0.540）。其他牙齿异常在IMC组中的发生率为51.92%，在对照组中的发生率为20.17%（P<0.05）。在IMC与其他四种牙齿异常之间发现了显著关联（P<0.05）：过小牙、桶状、其他埋伏牙和易位。对照组中所有异常的患病率较低。6.04%的患者存在IMC。患有这种情况的患者其他牙齿异常的患病率也较高。这些其他异常应作为早期诊断的风险指标。
