Automatic Dental Biofilm Detection Based on Deep Learning

alexandrossfakianakis shared this article with you from Inoreader Automatic Dental Biofilm Detection Based on Deep Learning via Journal of Clinical Periodontology Abstract Aim To estimate the automated biofilm detection capacity of the U-Net neural network on tooth images. Material and methods Two datasets of intraoral photographs taken in the frontal and lateral views of permanent and deciduous dentitions were employed. The first dataset consisted of 96 photographs taken before and after applying a disclosing agent and was used to validate the domain's expert biofilm annotation (intraclass correlation coefficient = 0.93). The second dataset comprised 480 photos, with or without orthodontic appliances, without disclosing agents, and was used to train the neural network to segment the biofilm. Dental biofilm labeled by the dentist (without disclosing agents) was considered the ground-truth. Segmentation performance was measured using accuracy, F1 score, sensitivity, and specificity. Results The U-Net model achieved an accuracy of 91.8%, F1 score of 60.6%, specificity of 94.4%, and sensitivity of 67.2%. The accuracy was higher in the presence of orthodontic appliances (92.6%). Conclusion Visually segmenting dental biofilm employing a U-Net is feasible and can assist professionals and patients in identifying dental biofilm, thus improving oral hygiene and health.
