Correlação entre a presença do ceceio anterior e os tipos de trespasse vertical interincisivos na dentadura decídua

Through a transversal epidemiological study, conducted with 333 Brazilian children, 157 males and 176 females, aged 3 to 6 years old, enrolled in a public preschool in São Paulo city, this study aimed to evaluate the prevalence of the different kinds of vertical interincisal trespass and the relationship between the occlusal aspects and anterior lisping. Metods: All children involved were submitted to a vertical interincisal trespass examination and to a phonoaudiologic evaluation. Besides the descriptive statistical analysis, including the calculation and tabulation of prevalence of the four kinds of interincisal trespass (normal overbite, deep overbite, edge to edge and open bite), the statistical significance was analyzed through the Qui-square test, at a significance level of 0.05 (95% confidence limits), in order to analyze possible associations between the factors. Results: The quantitative analysis of the data demonstrated the following prevalences: 1the different kinds of vertical interincisal trespass: 48.30% for normal overbite, 22.50% for deep overbite, 9.30% for edge to edge and 19.80% for open bite; and 2interdental lisping in relationship to the different kinds of vertical interincisal trespass: 42% for normal open bite, 12.50% for deep over bite, 12.50% for edge to edge and 33.30% for open bite. Conclusion: The statistical analysis of the data demonstrated that there was significance for individuals with anterior lisping in relation to open bite and statistical significance for individuals without anterior lisping in relation to deep overbite.
