Reporting items for root and canal morphology in case reports

Section	Number	Checklist item	Listed on page number
Type of report	1	Case report, case series.
Ethnic group/population	2	Details on ethnic group or population
Age*	3	The age range of the patient(s) must be reported.
Gender*	4	The gender of patient(s) must be reported.
Tooth type	5	Tooth (teeth) type included in the report.
Number of teeth included	6	Number of teeth included in the report.
Diagnostic device specifications and technique	7	This includes machine type, exposure settings Kv, mA, voxel size (if applicable), FOV (if applicable),angulation techniques, etc. Software(s) used for the analysis.
Qualitative analysis	8	Such as root canal configurations, evaluation of root canal shapes.
Quantitative analysis	9	Such as measuring volumes, areas, diameters, distances, angles.
How the evaluation process was performed	10	Such as examining the coronal/axial/sagittal sections in 3D imaging, or observing the canalbifurcations in 2D imaging under magnification, etc.
Magnification	11	Operating microscope or dental loupes or other.
		Magnification step and assisted illumination (if used) have to mentioned.
Modification of the access cavity	12	Conventional or changing the access cavity configuration to detect anatomy.
Exploration	13	Such as DG16 or other explorers.
Negotiation with or without troughing	14	Using ultrasonic tips or burs (troughing) or pre-curved files (without troughing).
Other special clinical observations	15	Such as bleeding point, NaOCl bubbling, etc.
Classification used	16	Classification for root canal configurations (with clear definitions for the orifice location and intercanal communications),root anomalies, accessory canals, etc.

^*In few occasions, case reports may have a presentation of both clinical case and extracted tooth – authors can mention “NA” if related information were not recorded for the extracted tooth
