Abstract(s)
Introdução: A disfunção temporomandibular (DTM) dolorosa está frequentemente associada a dor crónica, conduzindo limitações funcionais da mandíbula, níveis elevados de stresse e uma diminuição substancial da qualidade de vida. Compreender essas associações é essencial para orientar intervenções terapêuticas mais eficazes.
Objetivos: O estudo tem como objetivo comparar os níveis de stresse, qualidade de vida e funcionalidade mandibular entre adultos com DTM dolorosa e não dolorosa.
Materiais e Métodos: Foi conduzido um estudo descritivo, observacional e transversal, através de um questionário online aplicado através da plataforma Google Forms a 65 participantes da clínica dentária da Egas Moniz. Os participantes foram distribuídos em dois grupos: com DTM dolorosa e sem DTM dolorosa, com base na avaliação da dor por meio da Escala Visual Analógica (EVA). Utilizaram-se os instrumentos PSS-10, OHIP- 14 e JFLS-20 para avaliar, respetivamente, os níveis de stresse, a qualidade de vida relacionada com a saúde oral e a funcionalidade mandibular.
Resultados e Discussão: Os pacientes com DTM dolorosa tiveram escores significativamente superiores no OHIP-14 e JFLS-20 em comparação com os participantes sem dor (p < 0,001), confirmando o impacto negativo da dor na qualidade de vida e na função mandibular. No entanto, não se verificaram diferenças significativas
nos resultados do PSS-10 entre os grupos (p = 0,397), sugerindo que a dor crónica associada à DTM pode não influenciar diretamente os níveis de stresse percebido.
Verificou-se uma forte correlação entre os escores do OHIP-14 e do JFLS-20, sendo mais elevados em mulheres e participantes com 35 anos ou mais.
Conclusões: A DTM dolorosa compromete significativamente a qualidade de vida relacionada com a saúde oral e a função mandibular, embora não pareça afetar os níveis de stresse percebido. A forte correlação entre os resultados do JFLS-20 e do OHIP-14 evidencia que maiores limitações funcionais da mandíbula se traduzem diretamente num impacto negativo na vida quotidiana.
Introduction: Painful temporomandibular disorder (TMD) is often associated with chronic pain, leading to functional limitations of the jaw, high levels of stress, and a significant decrease in quality of life. Understanding these associations is essential for guiding more effective therapeutic interventions. Objectives: The aim of the study is to compare the levels of stress, quality of life, and mandibular functionality between adults with painful and non-painful TMD. Materials and Methods: A descriptive, observational, and cross-sectional study was conducted through an online questionnaire administered via the Google Forms platform to 65 participants from the Egas Moniz dental clinic. The participants were divided into two groups: with painful TMD and without painful TMD, based on pain assessment using the Visual Analog Scale (VAS). The instruments PSS-10, OHIP-14, and JFLS-20 were used to assess, respectively, stress levels, oral health-related quality of life, and mandibular functionality. Results and Discussion: Patients with painful TMD had significantly higher scores on the OHIP-14 and JFLS-20 compared to participants without pain (p < 0.001), confirming the negative impact of pain on quality of life and mandibular function. However, no significant differences were found in the PSS-10 results between the groups (p = 0.397), suggesting that chronic pain associated with TMD may not directly influence perceived stress levels. A strong positive correlation was observed between the OHIP-14 and JFLS-20 scores. Additionally, women and participants aged 35 or older showed higher scores on both scales. Conclusions: Painful TMD significantly compromises oral health-related quality of life and mandibular function, although it does not appear to affect perceived stress levels. The strong correlation between the JFLS-20 and OHIP-14 results highlights that greater functional limitations of the jaw directly translate into a negative impact on daily life.
