| Abstract: | PurposeThe purpose of the present study was to investigate the non-nutritive sucking habits of 18-month-old and 42-month-old children in order to determine the best method of advice to stop sucking habits.MethodWe examined the present situation of oral habits, the time of commencement and the time of discontinuation of the habits, the condition of occlusion, and the nursing behavior during the first 3 months from birth in the subjects.ResultsThe incidences of finger sucking and pacifier sucking habits in the 18-month-old children were 25.6% and 16.9%, respectively, and the incidences of the habits in the 42-month-old children were 27.2% and 16.8%, respectively. Most cases of the finger sucking habit continued until after 3 years of age, but the pacifier sucking habit was discontinued before 42 months of age. Open bite or maxillary protrusion was found in 70.7% of the 42-month-old children with persistent non-nutritive sucking habits but in only 6.8% of the 42-month-old participating children who had broken their sucking habits. We examined the correlation between non-nutritive sucking habits and nursing behavior. The incidence of oral habits was significantly higher in bottle-fed children than in breast-fed children. Pacifier sucking was more prevalent in children with a short breast feeding duration than in children with a normal feeding duration.ConclusionThe incidence of finger sucking is higher than that of pacifier sucking in Japan. Malocclusion caused by a sucking habit is more frequent in pacifier suckers than in finger suckers. The incidence of oral habits is higher in bottle-fed children than in breast-fed children. |
