Comparative study of the reliability and accuracy of anterior tooth root angulation measurements in lateral skull tele-radiography and CBCT from an image bank of the faculty of dentistry of the University of Cuenca

Purpose: The aim of the present study was to compare the reliability and accuracy of central incisor root angulation measurements performed by two different methods: CBCT and lateral skull teleradiography.

Materials and methods: The inclination angle in the vestibule-lingual direction of the upper and lower central incisor of 40 patients was measured by lateral skull teleradiography and CBCT and used excel 2016.

Results: The angulation of anterior tooth roots presented a statistically significant difference in the measurements performed in the lateral skull teleradiography and CBCT (p < 0.05).

Conclusion: Measurements of the vestibule­lingual inclination of the upper and lower central incisors performed on CBCT showed greater efficacy and reliability compared to measurements taken on TeleRx.
