Some studies indicate that Veillonella spp. can inhibit the acid production by S. mutans, potentially reducing the cariogenic process. Another aspect is the competition for substrates. Veillonella spp. utilize lactic acid, which is a by product of S. mutans metabolism, as a source of carbon.

The purpose of this study was to predict stunting in Rwanda using ANNs and the most recent DHS data from 2020.</p><p><strong>Methods: </strong>DHS 2020 dataset was used to train and test an ANN model for predicting stunting in children. The dataset, which included various child, parental, and socio-demographic characteristics, was split into 80% training data and 20% testing and validation data.
