Aberrant maxillary frenal attachment pose a problem of midline diastema and gingival recession. In children, they also cause difficulty in maintaining oral hygiene, accumulation of plaque which ultimately results in dental caries. Thus, a study was conducted with the objective of determining the prevalence of frenum in children. A total of 369 children from Kanti Children's Hospital (KCH) visiting the dental department were recruited in the study. The frenum was examined and classified by Placek's classification and Sewerin's classification. Chi-square test was used for showing association between frenum with age and gender. The most prevalent frenum type on the basis of type of attachment was gingival (51.2%), followed by the mucosal type (43.6%), papillary penetrating type (2.7%), and papillary type (2.5%). According to the morphological type, the most common frenum was found to be simple frenum (81%), simple frenum with appendix (7.9%), frenum with nodule (6.5%), persistent tectolabial (2.2%), simple with nichum (1.6%), and bifid labial frenum (0.8%). The most common frenum was gingival frenum and simple frenum in children. Morphological frenum variants were associated with gender. The attachment of frenum fibres showed association with age. As the age progressed, the frenum was observed to migrate apically.
上颌系带异常附着会导致中线牙缝和牙龈退缩问题。在儿童中，它们还会导致口腔卫生维护困难、牙菌斑堆积，最终导致龋齿。因此，开展了一项研究，目的是确定儿童中系带的患病率。该研究共招募了369名来自坎蒂儿童医院牙科的儿童。根据普拉塞克分类法和塞韦林分类法对系带进行检查和分类。采用卡方检验来显示系带与年龄和性别的关联。根据附着类型，最常见的系带类型是牙龈型（51.2%），其次是黏膜型（43.6%）、乳头穿透型（2.7%）和乳头型（2.5%）。根据形态学类型，最常见的系带是单纯系带（81%）、带阑尾的单纯系带（7.9%）、带结节的系带（6.5%）、持续性唇腭系带（2.2%）、带尼楚姆的单纯系带（1.6%）和双叉唇系带（0.8%）。儿童中最常见的系带是牙龈系带和单纯系带。形态学上的系带变异与性别有关。系带纤维的附着与年龄有关。随着年龄的增长，观察到系带向根尖迁移。
