Hello,\nI have seen many dentists changing the pressure regulator setting. They are doing it to compensate the de-graded performance of Airotors. How often does a Dentist required change the pressure? Importantly, whether it is correct to change the factory setting of pressure? Does anyone know about any regulations/guidelines/standards to be followed? Increasing the pressure could be a potential risk to the Patient as well as Dentist. Please provide your opinion.
