Objective: To study the patient satisfaction and its influencing factors on out-patients of stomatology departments in Shenzhen.Methods: In October 2021，a questionnaire survey of outpatients was conducted in 60 institutions providing dental care services in Shenzhen through a face-to-face format.Descriptive statistics，chi-square test and binary logistic regression were used to analyze patient satisfaction and its influencing factors.Results: The results of analysis indicated that 88.21 %of out-patients were satisfied with medical treatment.The type of medical insurance，treatment area，difficulty of registration，waiting time for treatment，and medical expense were all significant influencing factors for the satisfaction of out-patients in the dental clinics (P＜0.05).Self-paying patients and patients from western dental medical institutions were more likely to be dissatisfied.More difficult to register，longer waiting time for treatment，and higher medical expense were negative factors that affected patient satisfaction.Conclusion: The patient satisfaction of out-patients of stomatology departments in Shenzhen was generally good，but there were some aspects to improve.It was suggested that the government should further improve the patient satisfaction by expanding the coverage of medical insurance and improving physical environment of waiting areas in medical institutions.
