Dental unit prototype with dental suction and handpiece micromotor parameters

Abstract

Abstract A dental unit is a device for dental examination and treatment, including drilling, filling, cleaning and examination. In 2018, Basic Health Research Center Indonesia recorded the proportion of oral and dental problems of 57.6% and 10.2% of those who received services from dental medical personnel. Equitable distribution of dental health services at public health centers for the middle to lower-income community still faces a lack of facilities due to the dental unit’s high cost. Judging from the above problems, the author wants to make an economical Dental Unit but has entered into the standard of a dental examination. In designing the dental suction device and handpiece, this micromotor utilizes an LCD display as a pressure reading on dental suction, which has been converted by the MPX4115C6U5V sensor as well as the micromotor handpiece. There are up and down buttons for selecting the rotation speed from 1000 RPM to 25000 RPM. The tests carried out include testing the suction pressure at dental suction and testing the rotational speed of the micromotor handpiece. Based on the results, the sensor used as a pressure reader for the calibrator tool has the largest correction value of 0.36 KPa at -10 KPa pressure measurement, the micromotor handpiece testing has the highest error of 2.2% and the lowest error of 0.3. %. Thus, it can be concluded that the design of the dental suction device and the micromotor handpiece can be used in the examination of teeth and mouth as a saliva suction device and tartar cleaning.
