Aim: the aim of this study is to investigate unstimulated salivary flow (USF) and stimulated salivary flow (SSF) in a sample of patients affected by Juvenile Idiopathic Arthritis (JIA). Methods: USF and SSF were collected from 38 randomly selected JIA patients visiting Orthodontics Clinic at Ospedale Maggiore Policlinico in Milan. The spitting method was used to collect repeated saliva samples. 3 samples were collected without stimulation consecutively for 5’ and 3 more samples were collected after stimulation by citric acid. A 1’ interval was spent measuring the sample with a graduated syringe after each 5’ period. The collection was performed between 9 a.m. and 10 a.m., at least 2 hours after the last intake of food or drink. The flow rate was calculated in milliliters per minute. Results: the sample included 30 females and 8 males. Age ranged between 6 and 28 years (mean = 13,5; median = 12). Mean flow rates resulted as follows: USF rate after 5’ = 0,395158; USF rate after 10’ = 0,365526 mL/min; USF after 15’ = 0,427895 mL/min. SSF rate after 5’ = 0,976474 mL/min; SSF rate after10’ = 0,991211 mL/min; SSF after 15’ = 1,011526mL/ min. SSF/USF ratio was maximum after 10’ (2,711735) and minimum after 15’ (2,363961). 22 patients wore orthodontic appliance and the 15 did not. No statistical difference in mean USF or mean SSF between these two groups has been appreciated. Conclusion: data confirm that JIA patients have lower USF and SSF compared to the general population. Salivary flow rates remain stable over a period of 15’. Orthodontic appliances seem not to influence USF and SSF.

Abstract
Aim: the aim of this study is to investigate unstimulated salivary flow (USF) and stimulated salivary flow (SSF) in a sample of patients affected by Juvenile Idiopathic Arthritis (JIA). Methods: USF and SSF were collected from 38 randomly selected JIA patients visiting Orthodontics Clinic at Ospedale Maggiore Policlinico in Milan. The spitting method was used to collect repeated saliva samples. 3 samples were collected without stimulation consecutively for 5’ and 3 more samples were collected after stimulation by citric acid. A 1’ interval was spent measuring the sample with a graduated syringe after each 5’ period. The collection was performed between 9 a.m. and 10 a.m., at least 2 hours after the last intake of food or drink. The flow rate was calculated in milliliters per minute. Results: the sample included 30 females and 8 males. Age ranged between 6 and 28 years (mean = 13,5; median = 12). Mean flow rates resulted as follows: USF rate after 5’ = 0,395158; USF rate after 10’ = 0,365526 mL/min; USF after 15’ = 0,427895 mL/min. SSF rate after 5’ = 0,976474 mL/min; SSF rate after10’ = 0,991211 mL/min; SSF after 15’ = 1,011526mL/ min. SSF/USF ratio was maximum after 10’ (2,711735) and minimum after 15’ (2,363961). 22 patients wore orthodontic appliance and the 15 did not. No statistical difference in mean USF or mean SSF between these two groups has been appreciated. Conclusion: data confirm that JIA patients have lower USF and SSF compared to the general population.
