The identification data of the participants about specific questions about the most frequent habits were collected in previously prepared files, the data were subjected to descriptive and statistics test. Results: the descriptive analysis showed that only 17% of the children had the characteristics of a normal occlusion, the remaining 83% had some type of malocclusion. Within the malocclusion, labial suction was the most prevalent with 16,1% of the entire sample. Class I molar and canine was the most frequent. Class molar I and canine was the most frequent. Chi square analysis determined that there is no dependency relationship between the type of habit and the prevalence of anterior open bite (p=0,69), whit a slightly higher proportion when considering labial suction.
