研究目的: |
构建人工智能模型解读CBCT影像,实现对三维龋坏病损和髓腔影像的自动分割,评价龋坏深度,并计算剩余牙本质厚度;阐明模型测量的龋坏深度与组织学龋坏深度及牙髓炎症程度的相关性。辅助医生高效评价龋坏深度、牙髓炎症状态和预测露髓风险,为深龋和牙髓炎治疗方案的制定和术式决策提供帮助。 |
||||||||||||||||||||||
|
Objectives of Study: |
Develop an AI model for interpreting CBCT images to achieve automatic segmentation of 3D carious lesions and pulp chamber morphology, automatically evaluate caries depth, and calculate remaining dentin thickness. Establish the correlation between model-measured caries depth and histological caries depth/pulp inflammation severity. This system will assist clinicians in efficiently assessing caries progression, evaluating pulp inflammatory status, and predicting pulp exposure risks, thereby providing decision-making support for treatment planning selection and operative strategy formulation in deep caries and pulpitis management. |
