To assess the correlation between different cheiloscopic patterns with the permanent molar relationships.
300 children who are 14-16 years old with completely erupted 2nd permanent molars upto occlusal table were recruited and the pattern of molar terminal plane was recorded in the proforma. Lip prints of these subjects were recorded with lipstick-cellophane method and middle 10mm of lower lip was analysed for the lip print pattern as suggested by Sivapathasundharam et al. The pattern were classified based on Tsuchihashi and Suzuki classification.
Type II (branched) pattern was the most predominant cheiloscopic pattern. The predominant patterns which related to the Angle's classification were; type I (complete vertical) pattern for class I, type IV (reticular) pattern for class II and presence of type IV (reticular) pattern and absence of type I' (incomplete vertical) pattern for class III. In class III molar relationship, males showed an increased type II (branched) pattern and females showed an increased type IV (reticluar) pattern.
Lip prints can provide an alternative to dermatoglyphics to predict malocclusions in permanent dentition. Further studies with larger sample size are required to provide an insight into its significant correlations. Cheiloscopy, Angle's classification, malocclusion.
评估不同唇纹模式与恒牙磨牙关系之间的相关性。
招募300名14 - 16岁、第二恒磨牙完全萌出至咬合平面的儿童，并在表格中记录磨牙终末平面的模式。采用口红 - 玻璃纸法记录这些受试者的唇纹，并按照西瓦帕塔桑德拉姆等人的建议，分析下唇中间10毫米的唇纹模式。根据土桥和铃木分类法对模式进行分类。
II型（分支型）模式是最主要的唇纹模式。与安氏分类相关的主要模式为：I类为I型（完全垂直型）模式，II类为IV型（网状型）模式，III类为IV型（网状型）模式且无I'型（不完全垂直型）模式。在III类磨牙关系中，男性II型（分支型）模式增加，女性IV型（网状型）模式增加。
唇纹可为预测恒牙列错牙合提供一种替代皮纹学的方法。需要进一步进行更大样本量的研究，以深入了解其显著相关性。唇纹学、安氏分类、错牙合。
