Objectives: The present study aimed to assess the level of mothers' knowledge toward cleft lip and palate and their experience concerning presurgical orthopedic management.

Materials and methods: This was a cross-sectional study where the mothers were invited to complete a self-administered validated and reliable questionnaire. The questionnaire included questions that aimed to assess mother's knowledge related to the most prevalent aspects of cleft lip and palate anomaly itself and additionally, questions associated with presurgical orthopedic treatment as an adjunct therapy. Descriptive statistics were used to define the characteristics of the study variables. Chi-square test was utilized to assess relationships between categorical variables.

Results: Totally, 145 mothers completed the survey (response rate was 73%). Forty-six (46%) of the mothers provided an incomplete or improper definition of the anomaly and 35 (24%) claimed that they know the cause of the anomaly. The majority of mothers did not identify family history as a risk factor; consanguinity was identified in 29% (n = 42). Of the total, 58 mothers (40%) agreed that dental management of CLP requires teamwork and the majority (n = 126, 87%) recognized the plastic surgeon as the most important specialist. Mothers aged 20-30 years old (n = 42, 53%), and those who are university graduates (n = 38, 48%), as well as employed mothers (n = 52, 66%) have in general a higher degree of knowledge regarding cleft lip and palate (P < 0.001). More than half of the mothers (n = 70, 57%) reported that presurgical orthopedic treatment was useful and needed for their infants.

Conclusions: Most of the mothers reported a high level of knowledge about cleft lip and palate and they experienced the usefulness of the orthopedic appliances for their infants. However, there was uncertainty in some parts such as definition, diagnosis, causes, and risk factors for cleft lip and palate. Therefore, understanding the causes of cleft lip and palate, as well as comprehensive education concerning the essential role of the orthopedic appliances to improve cleft lip and palate are crucial for mothers to improve their infants' quality of life.
