the first drinking simulator unit

introduction: current thermal cycling units fail to simulate the drinking behaviors, and oral balancing temperature. they cannot also simulate other oral conditions such as drink coloring, and chemicals like tea, coffee, carbonated and noncarbonated, citrus juices as well as alcoholic and nonalcoholic drinks and also saliva and milk itself. the main objective of this study is to introduce the designing and manufacturing the first drinking simulator unit (dsu) that reproduces the thermal, color and chemicalcycling as well as the drinking behavior and oral temperature in lab conditions uniquely. methods: the invented system generally has two parts: the hardware and the software parts. the hardware consists of the mechanical and electronic parts. the software part is responsible for controlling the heating and cooling systems, electric valves, the pumps, and automatic filling systems of tanks as well as the sensors of the machine. results: dsu is the first unit can reproduce the thermal, color and chemical cycling as well as the drinking behavior and oral temperature in lab conditions. different kinds of colored and acidic drinks and also other chemical materials such as bleaching substances as well as detergents and antiseptics used for dentistry, industrial and medical purposes can be tested by dsu. dsu has also to be considered as an appliance performing in-vitro researches on dental structures. conclusion: the invented system can greatly improve and validate the results of such researches.
