Background: The preoperative fasting guidelines are adhered to reduce the risk of pulmonary aspiration in pediatric patients. This study was planned to evaluate the effect of parental awareness on preoperative fasting compliance in children undergoing ambulatory dental treatment under general anesthesia (GA) and to determine the factors affecting this. Methods: Parents of 88 ASAI-II pediatric patients were included in this study. In the first part of the study, parents received instructions regarding their child's preoperative fasting through both verbal and written instructions during the anesthesia consultation. In the second part, when the patients came to the GA operating room, the parents were given a questionnaire to fill out by the anesthesiologist responsible for the surgical procedure. Results: The average fasting period in patients before GA was 10 hours for solid foods and 8 hours for clear liquids. The solid food fasting period of patients whose parents had high school education was found to be longer than the other groups, with an average of 11 hours (p = 0.017). To the question 'What could be the reason for starving your patient?', the patients whose parents answered, "Risk of vomiting" and "Risk of food escaping into the respiratory tract" had shorter periods of liquid fasting than those who gave other answers (p=0.002). To the question 'Why Did Your Patient Stay Fast for Longer Than Recommended?', 64 (72.7%) parents answered, 'I Didn't Want to Disrupt His Sleep,’, and 24 (27.3%) parents answered, 'No Reason.' Conclusion: Clear instructions, reminder calls, educational videos, and communication resources are necessary to better adapt parents and alleviate their concerns regarding children's fasting periods during the preoperative period.
