The upper labial frenum is a normal anatomic structure with inherent morphological variations. Frenum has variations depending upon the attachment of fibers along with the presence of structural variations.
The aim of this study was to evaluate the prevalence of frenal variations in a diverse ethnic population of Sundernagar, Himachal Pradesh.
This study was conducted on 500 subjects within age group of 16-40 years (285 females, 215 males). Intraoral examination was done to evaluate the variations in frenum and photographs were taken.
In this study, depending upon structural variations, normal frenum was most common followed by frenum with nodule while frenum with appendix was found to be least common. However, no significant difference was found between males and females (P > 0.05) with respect to all frenal attachments. Furthermore, other structural variations were found in the diverse population of Sundernagar, Himachal Pradesh.
Upper labial frenum is a small anatomical landmark in the oral cavity found to have diverse morphology. The dentist needs to give due importance for frenum assessment during the oral examination.
上唇系带是一种具有固有形态变异的正常解剖结构。系带会因纤维附着情况以及结构变异的存在而有所不同。
本研究的目的是评估喜马偕尔邦孙德讷格尔不同种族人群中系带变异的发生率。
本研究对500名年龄在16至40岁之间的受试者进行（285名女性，215名男性）。进行口腔检查以评估系带变异情况并拍摄照片。
在本研究中，根据结构变异，正常系带最为常见，其次是有结节的系带，而有阑尾样结构的系带最不常见。然而，在所有系带附着情况方面，男性和女性之间未发现显著差异（P > 0.05）。此外，在喜马偕尔邦孙德讷格尔的不同人群中还发现了其他结构变异。
上唇系带是口腔中一个小的解剖标志，具有多样的形态。牙医在口腔检查期间需要对系带评估给予应有的重视。
