Abstract(s)
A agenesia dentária é uma anomalia que indica a ausência de um ou mais dentes devido a um defeito de desenvolvimento. A agenesia dentária de terceiros molares é a mais frequente e tem impacto no planeamento dos cuidados em medicina dentária. A ausência congénita do terceiro molar pode ser vista não como uma anomalia, mas como uma evolução humana. Quando uma anomalia representa quase 25% da população, deverá continuar a ser considerada como tal?
O objetivo desta tese de investigação é avaliar a prevalência de agenesia de terceiros molares numa amostra de pacientes que frequentam as Clínicas Pedagógicas de Medicina Dentária da Faculdade de Ciências da Saúde da Universidade Fernando Pessoa (CPMD FCS-UFP), numa população jovem da zona norte de Portugal. Os pacientes avaliados tinham entre 12 e 18 anos aquando da aquisição da radiografia panorâmica. Esta investigação visa recolher dados exatos para um estudo de maior escala, procurando determinar se se trata de uma tendência progressiva. Para isso, foi realizada uma pesquisa bibliográfica nas bases de dados online PubMed, ScienceAdvances e ScienceDirect, e foi feita uma recolha de dados posteriormente analisada em programas estatísticos.
Os resultados obtidos mostram uma prevalência de 22,1% de agenesia na população jovem da zona norte de Portugal, sendo notória a diferença entre a agenesia na maxila e na mandíbula. Não foi identificado dimorfismo sexual ou diferença entre os lados. Além disso, não houve evidência estatisticamente significativa de uma evolução no aparecimento da agenesia de terceiros molares dentro da mesma geração.
Tooth agenesis is an anomaly that indicates the absence of one or more teeth due to a developmental defect. Third molar agenesis is the most common type of dental agenesis and has an impact on treatment planning in dentistry. The congenital absence of third molars can be seen not as an anomaly, but as human evolution. When an anomaly represents almost 25% of the population, should it still be considered as such? The objective of this research thesis is to evaluate the prevalence of third molar agenesis in a sample of patients attending the Dental Medicine Pedagogical Clinics of the Faculty of Health Sciences at Fernando Pessoa University (CPMD FCS-UFP) within a young population from northern Portugal. The patients evaluated were between 12 and 18 years old at the time of panoramic radiograph acquisition. This investigation aims to gather accurate data for a larger-scale study to determine whether this is actually a progressive trend. To this end, a bibliographical search was conducted in online databases such as PubMed, ScienceAdvances, and ScienceDirect, and data was subsequently analyzed using statistical software. The results show a prevalence of 22.1% of agenesis in the young population of northern Portugal, with a notable difference between agenesis in the maxilla and mandible. No sexual dimorphism or difference between sides was identified. Additionally, there was no statistically significant evidence of an evolutionary trend in third molar agenesis within the same generation.
