Parental knowledge of dental erosion and erosion-related risk factors among preschool children in Saudi Arabia: a cross-sectional study

Introduction Dental erosion, represent an escalating issue within children in Saudi Arabia, characterized by the chemical degradation of dental enamel due to nonbacterial acids. This study focuses on assessing parental knowledge regarding dental erosion and its risk factors. Methodology A cross-sectional study was conducted using a structured Arabic-language questionnaire distributed online. Data from 396 parents of preschool children (aged 3–6 years) from different regions in Saudi Arabia were collected through convenient sampling via social media messaging platforms. The sample size was based on convenience sampling. Descriptive analyses were performed and counts and percentages were reported. Chi-square tests were conducted. Results Among the participants, 80% had heard of dental erosion. However, only 51.6% correctly identified acids as the cause, while 40% of respondents incorrectly linked it to dental caries. Understanding of dental erosion varied significantly by participants’ education level ( p < 0.05). Most participants recognized erosion as a serious condition (73.8%) and reported it affected general health (84.8%). However, only 30.2% were aware of available treatments, whereas 62.3% knew prevention methods. Conclusion Although most parents in the sample had heard of erosion, many reported limited knowledge of available treatment options. Educational level influences knowledge and dental care behaviors. Additionally, dietary habits and inconsistent dental visits remain prevalent, underscoring the need for targeted public health education.
