In orthodontics, apart from essential diagnostic aids, there are so many soft tissue analyses in which lips are major part of concern. However, lip prints have never been used in orthodontics as diagnostic aid or forensic tool. Therefore, this study was designed to explore the possible association of lip prints with skeletal malocclusion.
A sample of 114 subjects in the age group of 18-30 years, from North Indian adult population were selected on the basis of skeletal class I, class II and class III malocclusion, each comprising of 38 subjects with equal number of males and females. Lip prints of all the individuals were recorded and digital soft copies of lateral cephalograms were taken. Lip prints were compared between different skeletal malocclusions.
It was found that branched lip pattern was most common in North Indian adult population with no sexual dimorphism. The Z-test for proportion showed that the prevalence of vertical lip pattern was significantly higher in subjects having skeletal class III malocclusion.
A definite co-relation of vertical lip patterns with skeletal class III malocclusion was revealed.
在正畸学中，除了基本的诊断辅助手段外，有许多软组织分析，其中嘴唇是主要关注部分。然而，唇纹从未在正畸学中用作诊断辅助手段或法医工具。因此，本研究旨在探讨唇纹与骨骼错合畸形之间可能存在的关联。
从北印度成年人群中选取114名年龄在18至30岁之间的受试者作为样本，根据骨骼I类、II类和III类错合畸形进行分组，每组38名受试者，男女数量相等。记录所有个体的唇纹，并拍摄头颅侧位片的数字软拷贝。比较不同骨骼错合畸形之间的唇纹。
发现分支状唇纹模式在北印度成年人群中最为常见，且不存在性别差异。比例的Z检验表明，骨骼III类错合畸形患者中垂直唇纹模式的患病率显著更高。
揭示了垂直唇纹模式与骨骼III类错合畸形之间存在明确的相关性。
