Knowledge and attitude of patients indicated extraction or impacted third molar surgery toward antibiotic use

Abstract

In Thailand, there is a significant gap in public knowledge about the use of antibiotics, and antibiotics are easily accessible. People prefer self-medication, leading to antibiotic resistance. Dentists play a role in the use of antibiotics. This study was designed to determine knowledge and attitude of patients related to antibiotic use if extraction or impacted third molar surgery is indicated. A cross-sectional survey with questionnaire was conducted at the Faculty of Dentistry, Chulalongkorn University. The questionnaire consisted of two main sections: demographic data and an evaluation of knowledge and attitude. A 5-point Likert scale was used. Bivariate analysis was conducted to explore the association between demographic data, knowledge, attitude, and the decision to use antibiotics. Independent variables with a p-value < 0.2 were entered into multiple logistic regression models. A significant association was found between respondents' knowledge or attitude and their decision to use antibiotics. Respondents who believed that antibiotics do not reduce pain and inflammation, aware that antibiotics are effective against bacteria, or thought that antibiotics do not accelerate recovery were less likely to use antibiotics after a dental procedure. In conclusion, patients' decision on self-medication with antibiotics after impacted third molar surgery or extraction is influenced by their knowledge and attitude.
