Digit sucking, a form of non-nutritive sucking, is a habit of concern to specialist in various fields such as psychiatrist, psychologist, pediatricians, pediatric dentists, orthodontist, speech pathologist and plastic surgeon. The habits have harmful unbalanced pressures to be born by the immature highly malleable alveolar ridges. Sucking behaviors have long been recognized to affect occlusion and dental arch characteristics. As early as 1870s, Campbell and Chandler recognized that prolonged finger or thumb sucking habits had deleterious effects on certain occlusal traits including anterior open bite, increased over jet and class II canine and molar relationships. However, little is known about digit sucking habit and its effect in a cleft lip and palate child as there is no literature till now reported on the digit sucking in a cleft lip patient.
吮指是一种非营养性吸吮形式，是精神病学家、心理学家、儿科医生、儿童牙医、正畸医生、言语病理学家和整形外科医生等各个领域的专家所关注的一种习惯。这些习惯会对尚未成熟且可塑性很强的牙槽嵴产生有害的不均衡压力。长期以来，人们一直认识到吸吮行为会影响咬合和牙弓特征。早在19世纪70年代，坎贝尔和钱德勒就认识到，长期的吮指或吮拇习惯会对某些咬合特征产生有害影响，包括前牙开合、覆盖增加以及Ⅱ类犬牙和磨牙关系。然而，对于唇腭裂患儿的吮指习惯及其影响知之甚少，因为迄今为止尚无关于唇裂患者吮指情况的文献报道。
