摘要: 目的:构建基于深度学习的人工智能模型,利用便携式口腔内窥镜图像实现牙周疾病的早期筛查与检测。方法:收集内窥镜拍摄的1206张牙周病变图像,经整理、清洗与规范标注后,按7∶1∶1划分为训练集、验证集和测试集。采用YOLOv11模型进行训练与测试,使用精确度、召回率、F1分数及平均精度均值评估模型性能。结果:测试集中,模型在交并比(intersection over union,IoU)阈值为0.5时的平均精度为0.8044,F1分数为0.7953。牙龈退缩、牙龈红肿和牙结石的识别平均精度分别为0.7861、0.8511和0.7761。结论:所构建的深度学习模型能够低成本实现牙周疾病的早期筛查,为人工智能在牙周病早期检测中的应用提供了重要参考。

Abstract: Objective: To develop a deep learning-based AI model for early screening and detection of periodontal diseases using images from a portable oral endoscope. Methods: A dataset of 1206 periodontal disease images captured by the endoscope was constructed. After data curation, cleaning, and standardized annotation, the dataset was split into training, validation, and test sets in a 7∶1∶1 ratio. The YOLOv11 model was employed for training and evaluation, with performance assessed using precision, recall, F1-score, and mean average precision (mAP). Results: On the test set, the model achieved an mAP of 0.8044 at an IoU threshold of 0.5 and an F1-score of 0.7953. The average precision for detecting gingival recession, gingival redness and swelling, and dental calculus was 0.7861, 0.8511, and 0.7761, respectively. Conclusion: The developed deep learning model enables low-cost early screening of periodontal diseases and provides a valuable reference for the application of AI in early periodontal disease detection.
