Abstract

This study aims to propose a new model to predict the specific treatment effectiveness at site level by analyzing massive amounts of periodontal clinical data with deep learning methods.In light of the low accuracy of current tools, the proposed models cannot fully meet the needs of clinical effectiveness prediction and cannot be applied to on site level prognosis development and formulation of specific treatment plan.Periodontal examination data of 9273 Chinese patients were extracted and used to propose a Sequence-to-Sequence model after performing data management and reconstruction. The model was optimized by introducing the Attention mechanism.In the test set, the model obtained an average site-level probing depth (PD) accuracy (defined as the proportion of sites with <1 mm deviation of the predicted result from the true value) of 92.4% and high sensitivity (98.6%) for the pocket closure variable. For sites with baseline PD <5 mm, the model achieved a prediction accuracy of 94.6%, while it decreased to 79.9% at sites with PD ≥5 mm. In contrast, for teeth with initial mean PD ≥5 mm, the prediction accuracy significantly differed between molars and non-molars.Our model is the first to predict the site-level effectiveness with high accuracy and sensitivity. Future prediction models should incorporate deep learning for improved clinical prediction.© 2023 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
