Introdução: A má oclusão de Classe III é caracterizada por um maxilar inferior avançado em relação ao superior. Isso pode levar a um perfil facial côncavo e resultar numa discrepância significativa entre o tamanho das arcadas dentárias superior e inferior. Nesta má oclusão de Classe III, a relação molar é caracterizada por um avanço dos molares inferiores em relação aos superiores. Isto pode criar uma oclusão invertida nos incisivos centrais, com os molares inferiores posicionados anteriormente aos molares superiores. As relações caninas podem refletir a discrepância molar, evidenciando frequentemente avanço dos caninos inferiores em relação aos caninos superiores. A correção desta má oclusão muitas vezes requer tratamento ortodôntico precoce, de forma a minimizar a severidade da má oclusão, permitindo uma melhor função dentária e estética. Objetivo: O seguinte estudo teve como objetivo identificar qual a má oclusão mais prevalente na população odontopediátrica que recorre à Clínica Pedagógica de Medicina Dentária da Universidade Fernando Pessoa (UFP). Metodologia: O estudo consiste na análise de dados recolhidos através dos ficheiros clínicos, tais como a data de nascimento e o sexo e os parâmetros da oclusão no plano vertical, transversal e horizontal. Com recurso aos arquivos no programa NEWSOFTDS18 da Clínica Pedagógica de Medicina Dentária UFP, foram procurados todos os pacientes com idade compreendida entre os 6 anos e 15 anos. Em cada paciente foram recolhidas as informações relativas à má oclusão dentária. Inicialmente foi realizada a recolha dos parâmetros da oclusão no plano sagital para avaliar a prevalência da má oclusão dentária de Classe III na população odontopediátrica na Clínica Pedagógica de Medicina Dentária da UFP. Posteriormente, foi criada uma tabela com os dados obtidos, de forma a se poder fazer uma análise comparativa dos mesmos. Resultados: O estudo analisou uma amostra composta por 87 indivíduos do género masculino (48,3% da população total) e 93 do género feminino (51,7% da população total). Os intervalos de confiança para essas proporções foram de 40,8%–55,9% e 44,1%–59,2%, respetivamente. Durante a recolha dos dados, dos 87 pacientes do sexo masculino, em apenas 76 foi possível identificar a relação molar, sendo que apenas 10 pacientes tinham uma relação molar de Classe III, representando uma prevalência de 13,2%. Relativamente à relação canina, apenas foi possível identificar em 73 pacientes, sendo que apenas 9 apresentaram uma relação canina de Classe III, representando uma prevalência de 12,3%. Para os 93 pacientes do sexo feminino analisados, em 77 pacientes foi possível identificar a relação molar, com apenas 8 pacientes a apresentarem uma relação molar de Classe III, representando uma prevalência de 10,4%. No que diz respeito à relação canina, dos 93 pacientes femininos, apenas foi identificada a relação canina em 81, sendo que apenas 7 tinham uma relação canina de Classe III, representando uma prevalência de 8,64%. Conclusão: A prevalência de má oclusão de Classe III, de acordo com os resultados deste estudo na população odontopediátrica da Clínica Pedagógica de Medicina Dentária da UFP, é inferior quando comparada com a má oclusão de Classe I e de Classe II. Por isso, é fundamental o diagnóstico precoce da má oclusão de Classe III, de forma a poderem ser implementadas intervenções terapêuticas funcionais eficazes, permitindo um melhor controlo do crescimento, evitando uma maior severidade da má oclusão. O que poderá resultar em tratamentos mais previsíveis e menos complexos e com melhores resultados funcionais e estéticos.
Introduction: Class III malocclusion is characterized by an advanced lower jaw in relation to the upper jaw. This can lead to a concave facial profile and result in a significant discrepancy between the size of the upper and lower dental arches. In this Class III malocclusion, the molar ratio is characterized by an advancement of the lower molars in relation to the upper molars. This can create an inverted occlusion in the central incisors, with the lower molars positioned anterior to the upper molars. Canine relationships may reflect molar discrepancy, often showing advancement of the lower canines relative to the upper canines. Correction of this malocclusion often requires early orthodontic treatment in order to minimize the severity of the malocclusion, allowing for better dental function and aesthetics. Objective: The following study aimed to identify the most prevalent malocclusion in the pediatric dentistry population that uses the Pedagogical Dentistry Clinic at Fernando Pessoa University (UFP). Methodology: The study consists of the analysis of data collected through clinical files, such as date of birth and sex and occlusion parameters in the vertical, transversal and horizontal plane. Using the files in the NEWSOFTDS18 program of the UFP Dental Pedagogical Clinic, all patients aged between 6 years and 15 years were sought. Information regarding dental malocclusion was collected for each patient. Initially, occlusion parameters were collected in the sagittal plan to evaluate the prevalence of Class III dental malocclusion in the pediatric dentistry population at the Pedagogical Dentistry Clinic at UFP. Secondarily, a table was created with the data obtained, in order to make a comparative analysis of them. Results: The study analyzed a sample composed of 87 male individuals (48.3% of the total population) and 93 female individuals (51.7% of the total population). The confidence intervals for these proportions were 40.8%–55.9% and 44.1%–59.2%, respectively. During data collection, of the 87 male patients, it was possible to identify the molar relationship in only 76, with only 10 patients having a Class III molar relationship, representing a prevalence of 13.2%. Regarding the canine relationship, it was only possible to identify it in 73 patients, of which only 9 presented a Class III canine relationship, representing a prevalence of 12.3%. For the 93 female patients analyzed, it was possible to identify the molar relationship in 77 patients, with only 8 patients presenting a Class III molar relationship, representing a prevalence of 10.4%. Regarding the canine relationship, of the 93 female patients, only the canine relationship was identified in 81, with only 7 having a Class III canine relationship, representing a prevalence of 8.64%. Conclusion: The prevalence of Class III malocclusion, according to the results of this study in the pediatric dental population of the Pedagogical Dentistry Clinic of UFP, is lower when compared to Class I and Class II malocclusion. Therefore, early diagnosis of Class III malocclusion is essential so that effective functional therapeutic interventions can be implemented, allowing better growth control and avoiding greater severity of the malocclusion. This could result in more predictable and less complex treatments with better functional and aesthetic results.
