The distribution of the attachment of the maxillary labial frenum in the children of different ethnic backgrounds has not been studied extensively.
The purpose of this cross-sectional study was to examine the prevalence of the various types of maxillary labial frenum attachment in the children of different ethnic backgrounds.
Children (aged 1-18) attending a public health clinic in Lavrion, Greece, were clinically examined for maxillary frenum attachment location. Demographic information was recorded. Parents provided written informed consent.
The examined children were 226, with mean (± standard deviation) age of 8.5 ± 3.0 years. They were of Greek (51%), Albanian (20%), Turkish (12%), and Afghan (11%) descent. The prevalence of the maxillary labial frenum attachment was mucosal (10.2%), gingival (41.6%), papillary (22.1%), and papillary penetrating (26.1%). Frenum attachment differed significantly by age (P = 0.001). The age of children with mucosal- or gingival-type frenum was significantly greater than the age of children with papillary penetrating-type frenum. Frenum attachment did not differ by gender or ethnic background (P ≥ 0.20).
The results of this study suggest that, in children, ethnic background and gender are not associated with maxillary labial frenum attachment type, whereas age is strongly associated.
不同种族背景儿童的上唇系带附着分布尚未得到广泛研究。
本横断面研究旨在检查不同种族背景儿童的上唇系带附着的各种类型的患病率。
在希腊拉夫里翁的一家公共卫生诊所，对儿童的上唇系带附着位置进行临床检查。记录人口统计学信息。家长提供书面知情同意书。
检查的儿童为 226 名，平均（±标准差）年龄为 8.5 ± 3.0 岁。他们分别来自希腊裔（51%）、阿尔巴尼亚裔（20%）、土耳其裔（12%）和阿富汗裔（11%）。上唇系带附着的发生率为黏膜（10.2%）、牙龈（41.6%）、乳突（22.1%）和乳突穿透（26.1%）。系带附着在年龄上差异有统计学意义（P = 0.001）。具有黏膜或牙龈型系带的儿童的年龄明显大于具有乳突穿透型系带的儿童的年龄。系带附着在性别或种族背景上没有差异（P ≥ 0.20）。
本研究结果表明，在儿童中，种族背景和性别与上唇系带附着类型无关，而年龄与上唇系带附着类型密切相关。
