Dermatoglyphics can be utilised in clinical settings to identify those who are more likely to have impacted teeth. Additionally, dermatoglyphics looks to have potential as a non-invasive diagnostic method for predicting the presence or absence of an impacted tooth. The goal of this study was to look at the most common dermatoglyphic pattern in people who had or didn't have an impacted mandibular third molar teeth and see if there was a dermatoglyphic signature. A cross-sectional study with 180 participants was conducted (90 cases and 90 controls). The rolling impression technique was used to apply blue duplicating ink to participants' fingertips, which was then recorded. There was an increase in the frequency of the whorl-plain pattern in the right-hand ring finger (60%; p=0.028) and left-hand little finger (33.3%; p=0.009), as well as the loop-ulnar pattern in the right-hand middle finger (74.4%; p=0.024) in individuals with a predisposition to the presence of impacted teeth. The left-hand little finger was found to be the most predictive for impaction in a forward stepwise binary logistic regression analysis. Dermatoglyphics could be used as a non-invasive sign to predict whether or not a tooth is affected. Its value comes in early detection, which helps to avoid the surgical problems that come with symptomatic extraction of an impacted tooth.
指纹学可用于临床环境中，以识别那些更有可能出现阻生牙的人。此外，指纹学有望成为一种非侵入性诊断方法，用于预测阻生牙的存在或不存在。本研究的目的是观察有或没有下颌第三磨牙阻生的人中最常见的指纹模式，看看是否存在指纹特征。这是一项横断面研究，共有 180 名参与者（90 例病例和 90 例对照）。采用滚印技术将蓝色复制墨水应用于参与者的指尖，然后记录下来。在易发生阻生牙的个体中，右手无名指（60%；p=0.028）和左手小指（33.3%；p=0.009）的涡纹-平纹模式以及右手中指（74.4%；p=0.024）的环斗纹模式的出现频率增加。在向前逐步二元逻辑回归分析中，左手小指被发现对阻生最具预测性。指纹学可作为一种非侵入性标志，用于预测牙齿是否受到影响。它的价值在于早期发现，这有助于避免因阻生牙出现症状而进行手术拔除所带来的问题。
