Tokyo, March 20 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000060981) titled 'Development of a radiation dose reduction method for cone-beam CT for dental use with small-data MTANN AI imaging' on March 19.
Study Type:
Interventional
Study Design:
Basic Design - Parallel
Randomization - Non-randomized
Blinding - Double blind -all involved are blinded
Control - Dose comparison
Primary Sponsor:
Institute - Institute of Science Tokyo
Condition:
Condition - A research of Cone-beam CT imaging for periodontitis.
Classification by malignancy - Others
Genomic information - NO
Objective:
Narrative objectives1 - Cone-beam CT for dental use (CBCT) is widely used in dental care, but it tends to result in higher patient radiation doses compared to other X-ray examinations such as periapical radiography and panoramic radiography. In this study, we applied a Massive Training Artificial Neural Network (MTANN), a small-data AI, to CBCT images and developed an AI model that predicts high-dose images even under low-dose conditions. The purpose of this study is to investigate whether this AI model is effective for actual clinical images.
Basic objectives2 - Efficacy
Intervention:
Interventions/Control_1 - From June 2025 to March 2028, patients who visit the periodontal disease outpatient clinic at Institute of Science Tokyo Hospital and meet the criteria of Section 4.2 of the research protocol (selection policy for research subjects) will undergo low-dose radiography in addition to standard clinical dose radiography. The planned number of cases is 60.
