Early sucking activity may influence the growth of the craniofacial complex. It was well documented that the processes of breast feeding and bottle feeding involve different oro-facial muscles, leading to different effects on the harmonic growth of maxilla and dental arches . The aim of this study was to analyze the influence of breast, bottle and complementary feeding on the presence of non nutritive sucking habits in children after their first year of life and to assess the effects of non nutritive sucking habits on occlusion in mixed dentition. A group of 1500 healthy Egyptian children aged seven to eleven years old, were selected. Data about the child feeding method and the occurrence of oral habit such as dummy and pacifier sucking and the duration of habit were collected by a questionnaire and confirmed by personal interview. Clinical examination was performed in centric occlusion and occlusal evaluation included detecting the presence or absence of anterior open bite and posterior crossbite . The results showed that there was a statistically significant difference between feeding methods and development of oral habits and also between feeding methods and malocclusion. However, there was no correlation found between oral habits and malocclusion
