Abstract: Hyperuricemia has been studied extensively. However studies on salivary flow rate (SFR; ml/min) in unstimulated saliva (USS) and stimulated saliva (SS) conditions and oral dryness (OD) in subjects with hyperuricemia (HUS) have never been conducted. Current studies showed significantly decreased values in presence of OD (ODP) compared to absence of OD (ODA) in USS both for NUS (normouricemic subjects; p=0.0001) and HUS (p=0.0170). Furthermore, OD comparisons gave significantly decreased values in ODP compared to ODA in SS both for NUS (p=0.0049) and HUS (p=0.0444). In view of the significance in hyperuricemic subjects the “flow rate of unstimulated saliva (USS) and stimulated saliva (SS) decreases significantly in hyperuricemic subjects with oral dryness present (ODP)”. Conclusively, it is suggested that the salivary digestion affected in hyperuricemia can be diagnosed by investigating the salivary composition and flow rate.
