“…A most recent technology which provide 3-D radiographic image was cone beam computed tomography CBCT. It has a superior image quality in relation to conventional digital radiograph and give an accurate measurement for direction of the curvature of RE and position of its canal opening in relation to other canals in mandibular first molar for anatomical analysis (16)(17)(18)(19) . Hence digital perapical radiographs were used for initial monitoring of the existence of RE & CBCT were used for confirmation and detecting a variation in the position of RE.…”

Purpose: of this cross-sectional study was to determine the proportion of permanent mandibular first molar teeth with three roots among the Egyptian population. Material and methods:In total, 479 digital periapical radiographs were screened & evaluated to get 312 samples for the study. The 312 studied subject,137 male and 175 females, aged range from 19 to 70 years. Symmetry, gender, and frequency of existence of third root in mandibular first molars were assessed and analyzed using chi square test. Two examiner evaluated the radiographic characteristics of the radix entomolaris (RE). Cohen kappa test was used to assess intraexaminer variability. Results:The prevalence of RE was 2.91 % (4/10)in male, 3.42% (6/10) in female. Total Prevalence of RE in mandibular first molar was 3.12 %. There was no significant difference regarding to gender as p = 0.862. The Prevalence RE showed no statistically significant regarding to the position either unilateral or Bilateral (p=0.342) Conclusion:The overall prevalence of the RE is 3.12% in the mandibular first in the Egyptian population.
