Relação entre má oclusão e hábitos orais em respiradores orais

Abstract

The objective of this study was to verify the relationship between malocclusion and deleterious oral habits in a group of mouth breathing. This study was accomplished through the analysis of data of the 41 children’s handbooks, with ages between 7 and 12 years, being 21 of the masculine sex and 20 of the feminine sex, all mouth breathing. The collected information was organized in a database in the program Excel, being considered the variables: age, sex, presence and type of oral habit, and presence and type of malocclusion. The obtained results demonstrated that, all of the children presented some type of malocclusion, with prevalence of class II of Angle, and accentuated overjet; among the habits, the more incident was it of placement of objects in the mouth, although all of the children have presented a, or more deleterious habits; in the crossing of the variables, the only relationship found significant statistics was between the habit of licking lips and accentuated overjet. It could be ended that, in that sample, the presence of deleterious habits didn’t go decisive for the installation of the malocclusions, that the mouth breathing might have unchained the malocclusions in that group and that, the association of the deleterious habits with the mouth breathing, might have acted as aggravating factor for the installation, or development of the malocclusions in those children.
