Thesis Abstract
Early detection of dental caries in primary teeth remains a significant challenge in pediatric dentistry due to limitations in conventional diagnostic methods, which often result in late diagnosis and increased risk of secondary complications. This study aims to develop an artificial intelligence (AI)-powered diagnostic tool capable of identifying early-stage caries in primary teeth with high accuracy, thereby enabling prompt intervention and improved oral health outcomes among children. The research focuses on designing, training, and validating a machine learning model that leverages dental imaging data, including intraoral photographs and radiographs, to facilitate real-time caries detection. The primary objectives include (1) collecting a comprehensive dataset of annotated dental images of primary teeth from a sample population of 600 children aged 3 to 6 years across dental clinics; (2) developing a convolutional neural network (CNN) model trained to distinguish between healthy and early carious lesions; (3) evaluating the model’s diagnostic accuracy through metrics such as precision, recall, F1 score, and area under the receiver operating characteristic (ROC) curve; and (4) comparing the AI tool’s performance with that of expert pediatric dentists to establish its clinical viability. Employing an exploratory sequential mixed-methods design, the study integrates quantitative data analysis with qualitative expert assessments. The population comprises children presenting for routine dental check-ups at urban pediatric dental clinics. The sample size of 600 images was determined based on power analysis to achieve 80% sensitivity and 95% confidence level, with stratified random sampling to ensure representation of various lesion stages. Data collection involved digital intraoral photographs and bitewing radiographs, which were annotated by a panel of three experienced pediatric dentists using a standardized classification system for carious lesions. The research utilized TensorFlow and Keras libraries to develop and train the CNN, employing transfer learning with pretrained models such as ResNet50 to optimize performance. Cross-validation techniques and hyperparameter tuning were applied to prevent overfitting and enhance model generalizability. The diagnostic performance was analyzed through statistical tests, including McNemar’s test for paired proportions and receiver operating characteristic (ROC) analysis. Expected findings indicate that the developed AI diagnostic tool will demonstrate a sensitivity of approximately 89%, specificity of 85%, and an area under the ROC curve (AUC) of 0.91, outperforming traditional visual-tactile examination and comparable to expert clinicians. The model's interpretability will be enhanced through saliency mapping techniques such as Grad-CAM, providing visual explanations of the regions influencing diagnosis. The study contributes novel insights into the application of advanced deep learning architectures in pediatric dental diagnostics, bridging the gap in early detection technology, and offers a scalable, accessible instrument for routine clinical and community-based screenings. The study concludes that integrating AI-driven diagnostic tools into pediatric dental practices significantly enhances early caries detection accuracy, facilitating timely preventive measures. Recommendations include further validation with larger, diverse populations, integration strategies for electronic health records, and training modules for clinicians to effectively utilize AI tools. Future research should explore longitudinal assessments of AI-assisted diagnosis impacting treatment outcomes and patient satisfaction, reinforcing the potential of ICT innovations to transform pediatric dental healthcare delivery.Thesis Overview
This research focuses on developing a computer-based tool that uses artificial intelligence (AI) to detect early signs of tooth decay, called caries, in primary (baby) teeth. Early detection of caries is important because it allows for timely treatment, which can prevent more serious dental problems later on. Currently, dentists use visual examinations and X-rays to diagnose early caries, but these methods can sometimes miss subtle signs or expose patients to radiation. The goal of this study is to create a more accurate, safe, and efficient diagnostic method using AI. The researcher will begin by reviewing existing dental imaging techniques and AI methods used in medical diagnosis. The next step involves collecting a dataset of images of primary teeth, including healthy teeth and those with early caries, obtained from dental clinics. These images will be labeled and classified by experienced dentists to serve as training data. Using machine learning algorithms such as convolutional neural networks (CNNs), the AI model will be trained to recognize patterns associated with early caries. The performance of the model will be tested with a separate set of images, and its accuracy, sensitivity, and specificity will be evaluated through statistical analysis. The researcher will analyze the results using metrics such as confusion matrices and ROC curves to determine how well the AI tool can classify teeth accurately. The study aims to identify key visual features that the AI concentrates on when detecting early decay, contributing new insights into the visual markers of initial caries. This research will contribute to knowledge by providing a novel, automated diagnostic tool that can be integrated into routine dental practice, making early detection more accessible, consistent, and safe. The expected outcome is an AI system capable of significantly improving early caries diagnosis in primary teeth, ultimately supporting better preventive dental care for children. The study could pave the way for further advancements in computer-aided diagnosis in pediatric dentistry.Blazingprojects Mobile App
