^*SP-stimulated parotid; UP- unstimulated parotid; SS- stimulated submandibular/sublingual; US- unstimulated submandibular/sublingual. T-car – number of teeth with coronal caries, r-car – number of teeth with root caries, ts-car – the number of tooth surfaces with coronal caries and rs-car number of tooth surfaces with root caries
