Resumo(s)
Introdução: A Síndrome de Ardor Bucal (SAB) é uma condição crónica caraterizada pela presença de dor, do tipo ardor, sentida superficialmente na mucosa oral, por mais de 2 horas por dia durante mais de 3 meses, tendo sido excluídas eventuais causas locais ou sistémicas. Surge, muitas vezes, associada a sintomas como a xerostomia e a disgeusia. Vários estudos sugerem uma associação da SAB com fatores psicológicos ou psiquiátricos, como ansiedade, a depressão, a insónia ou a hipocondria. Objetivo: Este estudo tem como objetivo caracterizar clínica e epidemiologicamente os doentes diagnosticados com SAB na Faculdade de Medicina Dentária da Universidade de Lisboa, bem como identificar possíveis associações estatísticas entre variáveis clínicas, demográficas e psicossociais. Materiais e Métodos: Foi realizado um estudo observacional descritivo transversal, do tipo série de casos, baseado na análise de 28 processos clínicos de doentes com diagnóstico de SAB. Os dados foram recolhidos de processos em suporte papel e digital e analisados com recurso ao software SPSS (v29.0). Resultados: A amostra estudada foi composta por 24 mulheres (85.7%) e 4 homens (14.3%), com uma média de idades de 66.96 anos. A língua foi a localização mais frequente da sintomatologia (64.3%), sendo os sintomas predominantemente bilaterais. A xerostomia foi referida por 60.7% dos doentes, mas apenas 14.3% apresentavam hipossialia. Ansiedade foi reportada em 42.9% dos casos e 57.1% encontravam-se medicados com psicofármacos. A dor inicial teve uma média de 8.63 (escala de 0 a 10), reduzindo para 3.86 na última consulta. O fármaco mais utilizado foi o clonazepam. Não foi possível identificar relações estatisticamente significativas entre as variáveis estudadas. Conclusão: Os dados resultantes deste estudo estão de acordo com a literatura científica publicada, reforçando padrões já descritos. Verifica-se, no entanto, uma possível sobreposição da SAB com a Perturbação de Sintomas Somáticos, o que poderá contribuir para uma melhor compreensão desta complexa entidade clínica, com forte impacto negativo na qualidade de vida dos doentes.
Introduction: Burning Mouth Syndrome (BMS) is a chronic condition characterized by a burning-type pain felt superficially on the oral mucosa for more than 2 hours per day over a period longer than 3 months, after excluding possible local or systemic causes. It often appears in association with symptoms such as xerostomia and dysgeusia. Several studies suggest a link between BMS and psychological or psychiatric factors, such as anxiety, depression, insomnia, or hypochondria. Aim: This study aims to clinically and epidemiologically characterize patients diagnosed with BMS at the Faculty of Dental Medicine, University of Lisbon, as well as to identify possible statistical associations between clinical, demographic, and psychosocial variables. Materials and methods: An observational, descriptive, cross-sectional case series study was conducted, based on the analysis of 28 clinical records of patients diagnosed with BMS. Data were collected from both paper and digital records and analyzed using SPSS software (v29.0). Results: The study sample consisted of 24 women (85.7%) and 4 men (14.3%), with a mean age of 66.96 years. The tongue was the most common location of symptoms (64.3%), with symptoms predominantly bilateral. Xerostomia was reported by 60.7% of patients, but only 14.3% had hyposalivation. Anxiety was reported in 42.9% of cases, and 57.1% were taking psychotropic medication. The initial pain had a mean score of 8.63 (on a scale from 0 to 10), decreasing to 3.86 at the last appointment. The most commonly used drug was clonazepam. No statistically significant relationships were found between the studied variables. Conclusion: The results of this study are consistent with the published scientific literature, reinforcing previously described patterns. However, a possible overlap between BMS and Somatic Symptom Disorder was observed, which may contribute to a better understanding of this complex clinical entity, which has a strong negative impact on patients’ quality of life.
