RESUMO
Muscular activity of the lips, cheeks, and the tongue are important factors, which not only guide the occlusal development but also affect the growth of the jaws. Bottle feeding has been known to cause a myriad of changes in the oro-facial development. But the adverse effects of feeding practices with respect to developing dentition has been a subject of controversy. Hence a study was designed with the aim and objectives to check the commonly adopted feeding practices in South Kanara, to compare the occlusion of 3-to 5-year-old children with breast feeding, bottle feeding or combination, and to check whether prolonged feeding has any adverse influence on developing dentition. A total of 250 questionnaires were distributed to parents of 3- to 5-year-old children of which 153 were chosen for recording the impression and for studying the occlusion under various parameters. The results of the study indicated definite potential hazards of prolonged breast and bottle feeding especially with a tendency to develop openbite and posterior crossbite. It also suggested that an early preventive and interceptive approach.
