Tooth size measurements from the deciduous dentitions of 52 Spanish children.

Dataset of mesiodistal and buccolingual crown measurements from 712 deciduous teeth (incisors, canines, and molars) belonging to 52 Spanish children. This collection is unusual and especially valuable because it represents at least ten associated teeth from each individual. Measurements were obtained following standardized odontometric protocols to ensure accuracy and comparability. Unlike other studies, here we provide all individual measurements, making it the first openly available reference collection of raw deciduous tooth metrics derived from a well-documented and ethically-sourced sample. These data enable exploration of variability in primary tooth size, facilitate comparisons with other populations, and support studies on growth, development, and child forensic identification. By making this original dataset publicly available, we contribute a valuable tool for multiple scientific disciplines such as pediatric dentistry, forensic sciences, bioarchaeology, dental anthropology or human evolution among other disciplines.本数据集包含来自52名西班牙儿童的712颗乳牙的牙冠近远中径（mesiodistal）与颊舌径（buccolingual）测量数据，涉及牙齿类型包括切牙、尖牙及磨牙。该数据集的特殊性与珍贵性在于，每一位受试儿童均提供至少10颗关联牙齿的测量数据。所有测量均遵循标准化牙测量学（odontometric）规程开展，以确保数据的准确性与可比性。与其他同类研究不同，本数据集公开了全部单颗牙齿的原始测量数据，是首个源自记录完备且伦理合规样本的公开可用乳牙原始测量指标参考数据集。该数据集可用于探索乳牙尺寸的变异特征，便于与其他人群的相关数据开展对比研究，同时可为生长发育、儿童法医身份鉴定等领域的研究提供支持。通过公开该原始数据集，本研究为儿童牙科学、法医学、生物考古学、牙科人类学以及人类演化等多个学科领域提供了极具价值的研究工具。
