An optimized neural network can predict recurrent aphthous ulceration (RAU) using factors like gender, diet, and specific health markers. This AI model aids in understanding and forecasting RAU occurrence.

Area of Science:

  • Biomedical Informatics
  • Artificial Intelligence in Medicine
  • Oral Health Research

Background:

  • Recurrent aphthous ulceration (RAU) is a common oral condition with multifactorial etiology.
  • Accurate prediction of RAU occurrence can aid in early intervention and management.
  • Developing predictive models requires identifying key predisposing factors.

Purpose of the Study:

  • To develop and optimize an artificial neural network (ANN) for predicting recurrent aphthous ulceration (RAU).
  • To identify the most significant input data features for accurate RAU prediction using ANNs.

Main Methods:

  • Utilized artificial neural network (ANN) software with genetic algorithms for architecture optimization.
  • Trained ANNs using input/output data from 86 participants, including predisposing factors and RAU status.

  • Validated the optimized ANNs on a separate dataset of 10 participants.

    • Main Results:

    • The best-performing neural network incorporated gender, hematological (including ferritin), and mycological data.
    • Dietary factors such as vegetable and fruit consumption, alongside tooth brushing frequency, were significant predictors.
    • The model accurately predicted the presence or absence of recurrent aphthous ulceration.

    Conclusions:

    • Key factors for predicting RAU include gender, hemoglobin, vitamin B12, ferritin, red cell folate, and salivary candidal counts.
    • Oral hygiene practices (tooth brushing frequency) and dietary habits (fruit/vegetable intake) are crucial.
    • These identified factors are suitable for constructing ANNs to predict recurrent aphthous ulceration.
