title: The incidence, classification, etiology, and embryology of oral clefts.
abstract: There are numerous problems encountered among individuals with a cleft lip and/or cleft palate. Addressing these problems necessitates a multidisciplinary approach, requiring a team of experts to facilitate care for these individuals. Dentists play a vital role on the team. An orthodontist, pediatric dentist, oral maxillofacial surgeon, and prosthodontist usually represent the dental members of the team. The success of this team depends on expertise within each discipline but also depends on each member having a broad base of knowledge in general about oral clefts. An understanding of other disciplines and how they approach the treatment of oral clefts is important for each team member. Also, each team representative should appreciate the need to understand the causes of oral clefts, how clefts develop in utero, how various populations are affected, and how to recognize and classify an oral cleft. It is difficult to communicate effectively within the team if we fail to recognize the importance of expanding our knowledge to include other aspects of oral clefts beyond treatment perspectives. This article provides the orthodontist with basic information as it relates to the etiology of oral clefts (ie, genetics, teratogens, and medical conditions), the demographics and incidence of oral clefts, the embryology and classification of clefts.
