Uncertainty is significant when assessing a risk
of certain health care facility conditions
especially the facility that prone to the COVID
19 risk. One solution to deal with an uncertainty
in health situation assessment is through fuzzy
inference system. For that reason, this study
aims to develop fuzzy assisted system to assess
the safety of dental care related to the sets of
patient and environmental conditions. The fuzzy
system allows assessment based on the
patient body temperature, travel history,
dental care ventilation rate, and disinfection
frequency. The fuzzy system incorporates
several steps including fuzzification, fuzzy
regulation, and defuzzification. As a result of
this study, the fuzzy system is able to assess and
identify the risk of dental care according to the
patient health status and hygiene conditions
of dental care as well. To conclude, fuzzy
system used in this study has offered the
advantage of assessing at any situation as for
patient and environmental factor predicts the
safety of dental care.
