Analysis of Tooth Root Number

The aim of this cross-sectional study is to assess the number of roots in permanent teeth. For this reason, researchers will conduct an analysis of CBCT scans. The collected data will be used for epidemiological analysis, including an examination of differences in outcomes between male and female patients.

About this study

This study will involve analysis of anonymised CBCT images from Polish dental imaging facility. The analysis will include patients whose scans were obtained previously for diagnostic and therapeutic reasons and do not show significant artefacts. The primary outcome will be defined as the number of roots of each of the assessed teeth. Statistical analysis will be conducted in subgroups based on tooth type, patient gender, and patient age. This study has been approved by the bioethics committee.
