Brief summary

Oral dryness causes significant health problems both functional (difficulty speaking, chewing and swallowing) and structural problems in teeth (increased number of infections) and oral mucosa. The main objective of this study is to show an alternative treatment to help to stimulate the salivary secretion thus improving the quality of life of the patient. In this study, a salivary stimulation equipment using vibrotactile stimuli is shown. The system has been placed bilaterally in the parotid glands and assessed the efficacy of the salivary secretion by sialometry before and after the stimulation. The new proposal is capable of stimulating salivary secretion, in a significative way after 7 minutes of use, at least in the cases analyzed, and fulfills low-cost, easy-to-use and safe technical restrictions. In this setting, this paper suggests the performance of a deep clinical trial to measure the exact efficacy of the prototype and the times and frequencies needed to state the optimal treatment depending in each case

Intervention model description

The central idea of the device resides in transmitting the vibration generated by two vibrating modules to the two parotid glands through the superficial contact established between each vibrating module and the respective parotid gland, achieving the stimulation of both parotid glands simultaneously.
