Objective: This study was performed to investigate the particular matter of indoor air quality in dental clinic based on the legally PM10 concentration indoor reference value 100 μm/m3, and the result will be presented to the regulation and management.
Methods: This study is aimed to investigate the indoor air quality in the waiting room and treatment office, using the Dustmate for 7 hours, which had been set to work every 2 minutes an hour. The treatment office where dental personnel stays for a long period of time was measured, using the Dustmate for 24 hours, which had been set to work every 30 minutes an hour.
Results: The dental institution measurement for each location, the 2 multiuse facilities didn't exceed the Standard Act criteria 100 μm/m3. As a result of natural ventilation (morning treatment) and after the natural ventilation (afternoon treatment) by using natural ventilator during the lunch time, the standard concentration of PM10 has been reduced. After comparing the PM10 of treatment office and outdoor for 24 hours, both didn't exceed the indoor air quality standard level.
Conclusion: The dental personnel needs to clean the dental clinic regularly, and it is required to systematically manage by regular cleaning, and the installing an air purifier. An appropriate response plan needs to be considered for the dust problems.
