Hereditary lip prints have been studied by several researchers. However, the literature shows no consensus among the scientific community regarding this topic. Therefore, the aim of this study was to conduct a systematic review to gather evidence to clarify whether the surface structure of lip prints is hereditary and, consequently, if a familial relationship between individuals can be established through the analysis of lip prints. The systematic review was performed following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. A bibliographic survey was conducted in PubMed, Scopus, and Web of Science databases, restricted to articles published between 2010 and 2020. Studies were selected according to eligibility criteria, and then the study data were collected. The risk of bias of each study was assessed and applied as additional inclusion or exclusion criteria. The results of the articles eligible for analysis were synthesized by a descriptive approach. In the seven included studies, methodological variations, including the definition of similarity, that contribute to the heterogeneity of results were identified. The data gathered allowed to conclude that there is no strong scientific evidence to support the hypothesis of the existence of heredity in the surface structure of lip prints, since it was not proven that similarities between parents and children occur systematically in all families.
已有多位研究人员对遗传性唇纹进行了研究。然而，科学界在这一主题上并未达成共识。因此，本研究旨在进行系统综述，以收集证据来阐明唇纹的表面结构是否具有遗传性，以及是否可以通过唇纹分析来确定个体之间的家族关系。该系统评价按照 PRISMA（系统评价和荟萃分析的首选报告项目）指南进行。在 PubMed、Scopus 和 Web of Science 数据库中进行了文献检索，限制在 2010 年至 2020 年期间发表的文章。根据入选标准选择研究，并收集研究数据。评估了每个研究的偏倚风险，并将其作为额外的纳入或排除标准。通过描述性方法对符合分析条件的文章的结果进行综合。在纳入的 7 项研究中，发现了方法学上的差异，包括相似性的定义，这些差异导致了结果的异质性。所收集的数据表明，没有强有力的科学证据支持唇纹表面结构存在遗传性的假设，因为尚未证明父母和子女之间的相似性在所有家庭中都会系统地出现。
