Radiographic Assessment of Root/Crown Ratio and Short Root Anomaly: A Retrospective Study in Chinese Population

Research suggested that racial and gender differences may exist in tooth root development and the prevalence of short root anomaly (SRA). However, data on Asian and specifically Chinese populations were limited. This retrospective study aimed to evaluate the prevalence of SRA and the characteristics of the root-to-crown ratio (R/C ratio) within the Chinese population.
