AI-Powered Classification of Oral Lesions: Improving Early Detection and Diagnosis

Öz

Oral malignancies pose significant global health challenges, with oral squamous cell carcinoma (OSCC) being the most prevalent form. Early detection of potentially malignant oral disorders (OPMDs) such as leukoplakia and oral submucous fibrosis is crucial for improving patient prognosis. Traditional diagnostic approaches often face limitations like subjective interpretation and potential delays. This study aimed to develop and evaluate a deep learning-based model for the classification of oral lesions as benign or malignant using publicly available image datasets. Utilizing a modified VGG16 architecture and optimized preprocessing techniques, the model was trained on 330 annotated intraoral images and achieved an overall accuracy of 94.79%. Key performance metrics included a precision of 95.11%, sensitivity and specificity of 94.58%, and an F1 score of 94.74%. The model’s performance was comparable to or exceeded existing models with larger datasets, demonstrating its capability for effective feature extraction and reliable classification. The high area under the curve (AUC) value of 0.96 reinforced its potential for clinical application. While the model showed strong diagnostic capability, expanding the dataset size and incorporating a broader range of cases could further enhance generalizability. Future work should also consider integrating real-time image acquisition and optimizing computational processes for practical deployment. The findings underscore the promise of AI-driven diagnostic tools in supporting healthcare professionals by enabling timely, accurate, and scalable detection of oral malignancies, thereby contributing to improved patient care and outcomes. This study represents a significant step toward the practical application of AI in oral health diagnostics.

Yapay Zeka Destekli Oral Lezyon Sınıflandırması: Erken Tespit ve Tanıyı İyileştirme

Öz

"Ağız maligniteleri, oral skuamöz hücreli karsinomun (OSCC) en yaygın form olmasıyla birlikte önemli küresel sağlık sorunları oluşturmaktadır. Lökoplaki ve oral submuköz fibrozis gibi potansiyel olarak malign oral bozuklukların (OPMB) erken teşhisi, hasta prognozunu iyileştirmek açısından kritik öneme sahiptir. Geleneksel tanı yaklaşımları genellikle öznel yorumlama ve olası gecikmeler gibi sınırlamalarla karşı karşıya kalmaktadır. Bu çalışma, kamuya açık görüntü veri setlerini kullanarak oral lezyonların benign veya malign olarak sınıflandırılması için derin öğrenme tabanlı bir model geliştirmeyi ve değerlendirmeyi amaçlamıştır. Modifiye edilmiş bir VGG16 mimarisi ve optimize edilmiş ön işleme teknikleri kullanılarak model, 330 anotasyonlu intraoral görüntü üzerinde eğitilmiş ve %94,79 genel doğruluk elde etmiştir. Temel performans ölçütleri arasında %95,11 hassasiyet (precision), %94,58 duyarlılık (sensitivity) ve özgüllük (specificity) ile %94,74 F1 skoru bulunmaktadır. Modelin performansı, daha büyük veri setlerine sahip mevcut modellerle karşılaştırılabilir veya daha üstün olarak değerlendirilmiş ve etkili özellik çıkarımı ile güvenilir sınıflandırma yapma yeteneğini göstermiştir. 0,96’lık yüksek ROC eğrisi altındaki alan (AUC) değeri, klinik uygulama potansiyelini güçlendirmiştir. Model güçlü bir tanısal yetenek sergilemekle birlikte, veri setinin boyutunun genişletilmesi ve daha geniş bir vaka yelpazesinin dahil edilmesi, genelleştirilebilirliği daha da artırabilir. Gelecekteki çalışmalar, gerçek zamanlı görüntü alımını entegre etmeyi ve pratik uygulama için hesaplama süreçlerini optimize etmeyi de dikkate almalıdır. Bulgular, ağız malignitelerinin zamanında, doğru ve ölçeklenebilir bir şekilde tespit edilmesine olanak tanıyan AI tabanlı tanı araçlarının sağlık profesyonellerine destek sağlama vaadini vurgulamakta ve hasta bakımı ile sonuçlarının iyileştirilmesine katkıda bulunmaktadır. Bu çalışma, yapay zekânın ağız sağlığı tanısındaki pratik uygulamasına yönelik önemli bir adımı temsil etmektedir."
