Introdução: A má oclusão Classe II caracteriza-se por uma discrepância dentária ântero-posterior, frequentemente acompanhada de alterações esqueléticas, e pode ser dividida em divisão 1 (protusão dos incisivos superiores) e divisão 2 (retroinclinação dos incisivos superiores). O seu reconhecimento precoce permite a implementação de estratégias preventivas e corretivas pelos médicos dentistas.
Objetivo: Identificar a prevalência da má oclusão dentária de Classe II na população odontopediátrica da Clínica Pedagógica de Medicina Dentária da Universidade Fernando Pessoa, assim como compreender a sua distribuição por sexo.
Materiais e Métodos: Estudo transversal com dados recolhidos de 180 pacientes entre 6 e 15 anos, registados na base de dados NEWSOFTDS18® entre 2018 e 2024. A oclusão foi classificada segundo a definição de Angle.
Resultados: Entre os pacientes com relação molar diagnosticável, 43,4% dos rapazes e 48,1% das raparigas apresentaram Classe II. Na relação canina, a prevalência foi de 61,6% no sexo masculino e 54,32% no feminino. Quanto à subdivisão da Classe II, a divisão 1 foi mais prevalente (23,3% no total da amostra) que a divisão 2 (15,5%).
Conclusão: A má oclusão de Classe II é altamente prevalente nesta população, realçando a importância do diagnóstico precoce e do encaminhamento para tratamento ortodôntico, a fim de prevenir alterações funcionais e estéticas permanentes.
Introduction: Class II malocclusion is characterized by an anteroposterior dental discrepancy, often accompanied by skeletal alterations, and is classified into division 1 (protrusion of upper incisors) and division 2 (retroclination of upper incisors). Early identification enables preventive and corrective interventions by dentists. Objective: To determine the prevalence of Class II dental malocclusion in the pediatric dental population at the Pedagogical Clinic of Dental Medicine at Universidade Fernando Pessoa, as well as its distribution by sex. Materials and Methods: A cross-sectional study of 180 patients aged 6 to 15, based on clinical records from 2018 to 2024 using the NEWSOFTDS18® system. Occlusion was classified according to Angle’s definition. Results: Among patients with diagnosable molar relationship, 43.4% of males and 48.1% of females presented Class II. Regarding canine relationship, prevalence was 61.6% for males and 54.32% for females. Division 1 was more frequent (23.3%) than division 2 (15.5%) in the total sample. Conclusion: Class II malocclusion is highly prevalent in this pediatric population, highlighting the importance of early diagnosis and orthodontic intervention to prevent permanent functional and aesthetic consequences.
