Objectives: To determine the financial expenses incurred over the duration of the undergraduate dental course in Thailand Methods: A cross-sectional survey was conducted among all 658 dental undergraduates in Mahidol University, Thailand. Data were collected through the self-administered questionnaire, including (1) “Background”: household income, hometown, and residence during study, financial source(s), (2) "Expenses": Living costs including foods, transportations, rents, utility bills, and recreational expenses; Education-related expensesincluding textbooks, stationeries, uniforms, and student activities fees. A cost-median was used as a representation of the actual cost of each item. The mean differences of all expenses between groups before estimation was assessed by analysis of variance (ANOVA). The statistically significant difference was at p < 0.001. Results: A higher proportion of the participants' families financially supported, with household income between THB50,001 - 100,000 (2,118.1 – 4,235 USD), while only 5% have additional funding. Students who rented accommodation spent significantly higher yearly expenses than those who were not (p<0.001). The estimated adjusted cost of becoming a dentist is THB1,265,027 (53,580 USD) and THB1,823,027 (77,214 USD) for students living at home and renting accommodation, respectively. Conclusion: The cost of Thai dental education can be a significant financial burden, especially for students from disadvantaged socioeconomic status.

Objectives To determine the overall estimated financial impact and related expenses incurred over the duration of the undergraduate Dental Degree in Thailand. Methods A cross-sectional survey was conducted among all 658 dental undergraduates in Mahidol University, Thailand. Data was collected through a self-administered questionnaire, including the following information: (1) “Background and Demographics”: household income, hometown, residence during study and source(s) of any financial aid received; (2) “Living Expenses”: Living costs including food, transportation, rent, utility bills, and recreational expenses; (3) ”Education related expenses”: Including textbooks, stationeries, uniforms, and student activities fees. A cost-median was used as a baseline representation for the actual cost of each item. The mean differences of all expenses between groups before estimation was assessed by using the analysis of variance (ANOVA) method. The statistically significant differences were identified at p < 0.001. Results The estimated adjusted cost of becoming a dentist in Thailand is THB1,265,027 (36,143.63 USD) for students living at home and THB1,823,027 (52,086.49 USD) for those renting accommodation. Students who rented accommodation incurred significantly higher yearly living expenses than those who were living at home. (p < 0.001). The majority of participants (78.4%) were in households having a middle-to-high socioeconomic status. Ninety-five percentages of the participants’ received 100% financial support from their families with no additional source of income, which reflects no real diversity in the socioeconomic background of Dental Degree students. Conclusion The cost of a higher education Dental Degree in Thailand can be a significant barrier to entry and financial burden, especially for students from disadvantaged socioeconomic backgrounds. Government and Educational Policy makers need to pay more attention to this issue in order to provide equal opportunities for obtaining a University Dental Degree for all Thai students wishing to pursue this career path.
