Introdução: O número, tamanho e forma dentária podem surgir alteradas. Anomalias dentárias são morfologicamente diversas e refletem distúrbios de um ou mais estádios da odontogénese. A agenesia de dentes permanentes é a anomalia dentária mais frequente e uma das anomalias de desenvolvimento mais prevalente em humanos. Os pacientes ortodônticos aparentam uma maior prevalência de agenesias face à população geral. No entanto, mesmo verificando-se tal prevalência, muitas das vezes estas condições não são
consideradas pelos clínicos. A resolução destes casos requer equipas multi-disciplinares.
Objetivo: Avaliar a prevalência de anomalias dentárias numéricas (agenesias e supranumerários) excluindo terceiros molares, numa população clínica e aferir quais os dentes/região da cavidade oral mais afetada por este tipo de ocorrências e verificar se existe associação destas anomalias com o género.
Materiais e métodos: Foi elaborada uma revisão de literatura com base em artigos atuais e relevantes, os quais foram pesquisados no PubMed, Google Académico e Biblioteca Cochrane. Após uma pesquisa do estado de arte, deu-se início ao trabalho de investigação cujo material de estudo acentou na análise de um total de 421 processos clínicos de pacientes ortodônticos. Aplicaram-se critérios de inclusão e exclusão, viabilizando-se uma amostra final constituída por 147 indivíduos. Avaliou-se a história clínica e ortopantomografia maxilar desses 147 pacientes, registando-se o género, idade e a presença anomalias dentárias de número (agenesias e supranumerários).
Resultados e Conclusões: A amostra foi constituída por 86 indivíduos do sexo feminino (58,5%) e 61 do sexo masculino (41,5%). Desses indivíduos, 24 apresentavam algum tipo de anomalia numérica. A agenesia foi a anomalia mais registada e mais prevalente no sexo feminino enquanto que supranumerários foram mais prevalentes no sexo masculino.
Não foi possível estabelecer uma relação estatisticamente significativa entre a presença de anomalias e o género (p> 0,05).
Introduction: The number, size and shape of teeth may be altered. Dental anomalies are morphologically diverse and reflect disorders of one or more stages of odontogenesis. Agenesis of permanent teeth is a common dental anomaly and one of the most prevalent developmental anomalies in humans. Orthodontic patients appear to have a higher prevalence of agenesis compared to the general population. However, even with such prevalence, these conditions are often not considered by orthodontists. The resolution of these cases requires multidisciplinary teams. Objective: the objective is to evaluate the pre of numerical dental anomalies (agenesis and supernumerary teeth), excluding third molars, in a clinical population and to assess which teeth/region of the oral cavity are most affected by this type of occurrence and to verify if there is an association of these anomalies with gender. The aim of this dissertation was also to do a review of literature using articles that were accessed on PubMed, Google Academics and Cochrane library. Materials and methods: A literature review was prepared based on current and relevant articles, which were searched in PubMed, Google Academic and Cochrane Library. After a state-of-the-art survey, the investigation work began, whose study material was focused on the analysis of a total of 421 clinical files of orthodontic patients. Inclusion and exclusion criteria were applied, enabling a final sample consisting of 147 individuals. The clinical history and maxillary orthopantomography of these 147 patients were evaluated, recording the gender, age and presence of dental anomalies in number (agenesis and supernumerary). Results and Conclusions: The sample consisted in 86 females (58.5%) and 61 males (41.5%). Of these 147, 24 had some type of numerical anomalies. Agenesis was the most common and most prevalent anomaly in females, while supernumeraries were more prevalent in males. It was not possible to establish a statistically significant relationship between the presence of anomalies and gender (p>0.05).
