Participant demographic data (n = 655).

Background
Volunteering can be defined as activities a person does for free to help another person or group. Saudi Vision 2030 has a target of one million volunteers from the country by 2030. The aim of this study was to find out the frequencies of the motives, barriers, and experiences of volunteering dental students and dentists in Saudi Arabia.
Materials and methods
In this cross-sectional study, 655 dental students and dentists from 37 cities around Saudi Arabia answered a questionnaire of 59 questions derived from previous studies. The questionnaire was distributed through social media. SPSS software was used to analyze the data, with p-value of 0.05 as significant. Chi-square was used for analytical statistics.
Results
The chance to learn in a health-related field (84.58%) was the most motivating factor to volunteer, and the least motivating factor was financial compensation (46.72%). Females had multiple significantly higher motives percentages than males (p<0.05). The most prominent barrier was time constraints (74.50%), while the least important barrier was parents/family disapproval (28.85%). Lack of transportation was a more significant (p<0.001) barrier for females than males. Of the respondents, 74.50% had previously participated in volunteer work. Among those, 98.36% volunteered in Saudi Arabia and 6.97% volunteered outside of Saudi Arabia. Also, 46.31% volunteered during the COVID-19 pandemic.
Conclusions
A high percentage of dental students and dentists in Saudi Arabia engage in volunteer activities. Nevertheless, various impediments must be addressed to achieved the targeted key performance indicator of Saudi Arabia Vision 2030.
