ABSTRACT

Introduction: The aim of the study was to measure the flow rate of unstimulated parotid saliva among the study volunteers with a history of using hand held mobile phones on dominant and non-dominant side using a simple chromatography filter paper technique based on Iodine Starch colour reaction. Materials & Methods: In this study 120 subjects with good health were included. Patients were asked to sit in a quiet room with the head slightly tilted down. The starch iodide loaded chromatic paper was held at the opening of Stenson’s Duct for 2 minutes on dominant and non-dominant side, one side at a time basis. After 2 minutes the paper was taken out and the colouring reagent was added drop wise to the wet spots on the paper. Results: Out of 120 study group subjects, maximum numbers of subjects (50) were found to have three coloured spots in dominant side, while maximum numbers of subjects (48) were found to have 0coloured spots in non-dominant side. Difference between dominant and non-dominant side was found to be statistically significant. Discussion & Conclusion: In this study salivary flow rate was assessed using chromatography paper based on the Iodine starch reaction. Three coloured spots appeared on the paper for patients with decreased salivary flow rate, whereas for healthy subjects with normal flow rate there was one coloured spot or none.
