PRISMA Diagram, Data Extraction Tables, and Risk of Bias Assessments: Pink Teeth Systematic Review

This dataset contains supplementary materials supporting the article “A Systematic Review of the Postmortem Pink Teeth Phenomenon: Perspectives from Forensic Photography, Radiology, and Histopathology.” The systematic review, registered in PROSPERO (CRD420251083393) and conducted according to PRISMA 2020 guidelines, examined the forensic significance of the postmortem pink teeth phenomenon through photography, radiology, and histopathology.The dataset includes the PRISMA 2020 flow diagram, data extraction tables summarizing methodological characteristics and findings from 15 eligible studies, and risk of bias assessments performed using the Joanna Briggs Institute (JBI) checklist. These supplementary materials provide transparency, enable replication, and facilitate further analysis of how hemolyzed hemoglobin infiltration, environmental conditions, and forensic methods contribute to the discoloration of teeth after death.By making these materials openly accessible, the dataset enhances reproducibility, supports interdisciplinary research in forensic odontology, and strengthens the scientific basis for interpreting pink teeth as a supplementary indicator in medicolegal death investigations.本数据集包含支持论文《死后粉色牙齿现象的系统综述：法医摄影、放射学与组织病理学视角》的补充材料。该系统综述已在PROSPERO平台注册（编号：CRD420251083393），并严格遵循PRISMA 2020指南开展研究，通过法医摄影、放射学及组织病理学三个维度，探讨了死后粉色牙齿现象的法医学意义。数据集涵盖PRISMA 2020流程图、汇总15项符合纳入标准研究的方法学特征与研究结果的数据提取表，以及采用乔安娜·布里格斯研究所（Joanna Briggs Institute, JBI）偏倚风险清单完成的偏倚风险评估内容。这些补充材料可提升研究透明度、支持研究复现，并便于学界进一步分析溶血血红蛋白浸润、环境条件及法医检测方法如何导致死后牙齿变色。通过公开开放这些补充材料，本数据集可提升研究可复现性，助力法医牙科学领域的跨学科研究，并强化将粉色牙齿作为法医学死亡调查中补充性指标的科学解读依据。
