Study summary

Low-Dose CBCT Protocol for Pre-Surgical Evaluation of the Mandibular Third Molar.

CBCT investigations with standard and low dose protocol for evalutation of the mandibular third molar.

Read the detailed description

Two CBCT scans were acquired of each examination site: one scan using the standard clinical protocol (90kV, 5mA, 9.4s) and one, the low-dose protocol (90kV, 2mA, 9.4s). All exposures were made with a Veraviewepocs 3D F40 (J Morita Corp.; Kyoto, Japan) using a field of view (FOV) of 4.0 x 4.0 cm and a rotation mode of 180°, voxel size of 0.125 mm.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 30, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
