  1. CSRCs: C-shaped root canals, RGs: radicular grooves, MFPs: mandibular first premolars, MSPs: mandibular second premolars, MFMs: mandibular first molars, MSMs: mandibular second molars.
  2. aThe prevalence of CSRCs in MFPs of males was higher than that in females, while the prevalence of CSRCs in MSMs of females was higher than that in males.
