Abstract:
The present study investigated persistent digit sucking habits among referrals to a Hospital Orthodontic Department. In particular, the prevalence of habits and their effect on dentofacial morphology, dental occlusion and orthodontic treatment need were investigated. Over an eight month period 54 cases, or 6.1% of all new patients, were referred with persistent digit sucking habits. Two thirds were female, and the age range was 5 to 16 years. A Study Group of 44 cases over the age of 10 years was identified and compared with a Control Group of non digit sucking referred patients, matched for age and sex. The cephalometric data revealed digit sucking to be associated with a significant increase in maxillary prognathism, relative prognathism, maxillary incisor proclination and maxillary anteroposterior length, and to be associated with a significant reduction in interincisal angle and angulation of the maxillary plane to the cranial base. No significant differences were observed for mandibular incisor proclination, face height, maxillary mandibular plane angulation, mandibular length or cranial base characteristics. It was concluded that persistent digit sucking is an important aetiological factor for malocclusion in patients referred to a Hospital Orthodontic Department, exerting an influence in anteroposterior, vertical and transverse dimensions. Although some minor skeletal changes were detected, the changes were principally dentoalveolar.
