Measurement of Basic Structural Data of Chinese Teeth: This dataset collects normal physiological structural data of the oral and maxillofacial region, as well as relevant measurement data of deciduous and permanent teeth in Chinese populations. The specific measurement items include: a. Anatomical data of tooth morphology, covering total length of deciduous and permanent teeth, crown length, crown width, crown thickness, cervical width, cervical thickness, root length and root morphology; b. Anatomical data of pulp cavities and root canals, including pulp cavity morphology and root canal morphology system. The recruited subjects are strictly screened and divided into adults and children. Data collection is conducted strictly in accordance with standardized data acquisition protocols, with scientifically validated measurement methods, and the obtained numerical values are scientifically rigorous and reasonable.
