Abstract(s)
Objetivos: O estudo teve como finalidade avaliar a prevalência de erupções ectópicas de primeiros molares permanentes, e o seu grau de impactação, assim como sinais da sua autocorreção, através da análise de radiografias panorâmicas de pacientes pediátricos.
Materiais e métodos: O estudo foi realizado através da leitura das radiografias panorâmicas que constavam no arquivo das fichas clínicas dos pacientes que frequentam ou frequentaram a Clínica Pedagógica de Medicina Dentária da Faculdade de Ciências da Saúde da Universidade Fernando Pessoa.
Resultados: A prevalência de erupção ectópica de primeiros molares permanentes obtida foi de 3,2%, sendo que a maioria dos casos ocorreu na maxila e o dente mais comumente impactado foi o 26. O sexo masculino e crianças com idade igual ou inferior a 8,33 anos apresentaram uma frequência superior de erupção ectópica. Segundo as escalas utilizadas, os graus moderado e severo de impactação do primeiro molar permanente foram os mais observados. A prevalência da reabsorção no segundo molar temporário foi de 5,3 %, sendo superior na maxila. Crianças do sexo masculino e com idade igual ou inferior a 8,33 anos foram as mais afetadas. Dos casos analisados, 2% autocorrigiram-se.
Conclusões: Esta patologia requer uma atenção reforçada do médico dentista para ser diagnosticada, uma vez que na maioria dos casos se trata de um achado radiográfico. O acompanhamento ao longo do tempo e o estabelecimento de um plano de tratamento adequado são essenciais para prevenir uma má-oclusão.
Objectives: The purpose of the study was to assess the prevalence of ectopic eruptions of first permanent molars, and their degree of impaction, as well as signs of their self-correction, through the analysis of panoramic radiographs of pediatric patients. Materials and methods: The study was carried out by reading the panoramic radiographs that were included in the archive of the clinical records from patients who attend or have attended the Clínica Pedagógica de Medicina Dentária da Faculdade de Ciências da Saúde da Universidade Fernando Pessoa. Results: The prevalence of ectopic eruption of permanent first molars obtained was 3.2%, with most cases occurring in the maxilla and the most impacted tooth was 26. Males and children aged the same or younger to 8.33 years had a higher frequency of ectopic eruption. According to the scales used, the moderate and severe degrees of im-paction of the first permanent molar were the most frequently observed. The prevalence of resorption in the second temporary molar was 5.3%, with a higher occurrence in the maxilla. Male children aged 8.33 years or younger were the most affected. Among the cases, 2% self-corrected. Conclusions: This pathology requires increased attention from the dentist to be diagnosed, since in most cases it is a radiographic finding. Monitoring over time and establishing an adequate treatment plan are essential to prevent malocclusion.
