Abstract
The one ID card to every health facility of the 30-baht universal coverage project aims to increase
access to dental care services for Thai people based on primary care concept with services close to their
home including private dental clinics that registered as service units to the project. The objectives of this
cross-sectional study were to examine the relationship between factors influencing private dental clinics’
decision to participate, and the tendency to remain in the project. A questionnaire was developed
specifically as the research tool of this study. The questionnaire covered questions on the benefits to
the public sector, to the government sector, to entrepreneurs, and obstacles. The data were collected
between 3–13 June 2024 directed to all 63 dental clinics registered as service units in the National Health
Security system of Nakhon Ratchasima province. The rate of responses was equal to 57%. The results
revealed as follows. All aspects of the factors influencing decision making to participate in the project
of private dental clinics were not related to the tendency to remain in the one ID 30-Baht universal
coverage project (p > 0.05). Rates of payment per visit to private dental clinics were significantly related
to tendency to remain in the project (p = 0.003). Dental clinics viewing proper compensation rates tended to remain in the project. Such tendency was 10.7 times higher than clinics viewing that the compensation rate was too low (odds ratio = 10.7).
