Plain English summary of protocol

Background and study aims
Root canal treatment (endodontics) is a dental procedure that treats infection at the centre of a tooth. Successful endodontic treatments require a comprehensive knowledge of the root canal anatomy, so the aim of this study was to investigate the root number and morphology of the maxillary second molars (back teeth on the upper jaw) in Syrian patients.

Who can participate?
Patients aged between 15 and 65 years who had cone beam computed tomography (CBCT) scan images taken for orthodontic or surgical reasons Damascus University Faculty of Dentistry from November 2020 to January 2022

What does the study involve?
The CBCT images were examined by two endodontists. The detailed analysis included the number of roots, the number of canals and their configurations, bilateral symmetry, and relation to gender.

What are the possible benefits and risks of participating?
This study could improve our understanding of root canal anatomy and improve the outcomes of endodontic treatment. There are no risks as the patients are not exposed to radiation (for the CBCT scan) because of this study but rather because of other orthodontic or surgical reasons.

Where is the study run from?
Damascus University (Syria)

When is the study starting and how long is it expected to run for?
September 2020 to January 2022

Who is funding the study?

Health condition(s) or problem(s) studiedThe number of roots and configuration of the root canals of maxillary second molars across various levels (axial, coronal, sagittal, oblique, and 3D)
InterventionTwo experienced Endodontics performed image evaluation and data analysis of 250 CBCT images containing 500 maxillary second molars in patients aged between 15 and 65 years. Subsequently, a third dental specialist researcher randomly reviewed 10% of the sample. The study investigated the number of roots and configuration of the root canals of maxillary second molars across various levels (axial, coronal, sagittal, oblique, and 3D).
Intervention typeOther
Primary outcome measureNumber of roots in maxillary second molars and root canal configuration, recorded after being observed visually by two experienced Endodontics who performed CBCT image evaluation and data analysis across various levels (axial, coronal, sagittal, oblique, and 3D). Measured at a single timepoint for each patient and two experienced endodontics examined the CBCT images again 2 months later to ensure the accuracy of the recorded results.
Secondary outcome measuresThe symmetry of the number of roots in maxillary second molars and symmetry in the numbers and configuration of the root canal, recorded after being observed visually by two experienced Endodontics who performed CBCT image evaluation and data analysis across various levels (axial, coronal, sagittal, oblique, and 3D). Measured at a single timepoint for each patient and two experienced endodontics examined the CBCT images again 2 months later to ensure the accuracy of the recorded results.
