Kids under the age of 5 years generally spend most of their time with their parents. It has been found that young children's oral health maintenance and outcomes are influenced by their parent's knowledge and beliefs. This study was done to assess the parent's knowledge about the oral health of their kids aged 1-5 years. The study bases it findings on the survey conducted at the Diagnosis Clinic of the King Khalid University, Abha through a 20-items questionnaire, which was distributed to 425 parents by the researchers. Responses of the parents were recorded on a Likert Scale and multiple choices questions written in Arabic language. The results show insufficient knowledge of Saudi parents about their kids oral health. It also shows that oral health care awareness programs are very important to secure a healthy oral condition among kids. ª 2015 The Authors.
