RESUMO
This study was carried out to evaluate the knowledge and source of information about teeth bleaching among the adult population of Saudi Arabia. Moreover, to determine the level of satisfaction with the results after bleaching treatment. Methods: A cross-sectional study based on a self-administered online questionnaire. A simple random sample comprising of 1126 participants distributed across the five geographical regions of Saudi Arabia (middle, northern, southern, eastern and western). The data obtained was analyzed utilizing frequency distribution and Chi-square test (P ≤ 0.05). Results: There was no statistically significant difference in knowledge of bleaching in relation to geographical regions but the age and gender had a significant influence (p=0. 000), (p=0. 001) respectively. Respondents with age group (18- 24 years old) had a higher knowledge than other age groups. In addition, female participants have a higher knowledge than males. 52.6 % of these participants were satisfied with the results achieved after bleaching. Conclusion: There still exist certain doubts and misconceptions regarding the awareness of bleaching procedure and products, hence, more effort should be carried out to provide the public with proper information so that any decision made regarding teeth bleaching would be based on sound foundations.
