Abstract(s)
Objetivos: Este estudo piloto teve como objetivos a determinação da prevalência do desgaste dentário erosivo e sua distribuição em pacientes da Clínica Universitária Egas Moniz (CUEM).
Material e Métodos: Após aprovação da Comissão de Ética da Egas Moniz, 50 pacientes da CUEM foram selecionados aleatoriamente e assinaram um consentimento informado para participação no estudo. O desgaste dentário erosivo foi medido com o índice de Lussi, por um observador, calibrado previamente com um observador experiente na área. A calibração foi realizada em 10 pacientes da CUEM, escolhidos aleatoriamente, observados separadamente pelos dois observadores. O nível de concordância entre os dois observadores foi avaliado com a estatística kappa de Cohen.
Analisou-se estatisticamente a correlação entre as variáveis dependentes qualitativas:
“Erosão Global”, “Erosão Maxilar”, “Erosão Mandibular” e “Desgaste Anterior”, derivadas da classificação feita com o índice em estudo, e as variáveis independentes “Idade” e “Género”.
Resultados: A Erosão Global foi de 90% na amostra em estudo. Não foi encontrada uma associação estatisticamente significativa quer para as variáveis Idade e Erosão Global (p = 0.766) quer para Género e Erosão Global (p = 0.385). Mas, foi encontrada uma associação estatisticamente significativa entre a distribuição dos níveis de desgaste erosivo na maxila e na mandíbula (p = 0.007), bem como entre Erosão Global e Erosão Maxilar (p ≤ 0.001) e Erosão Global e Erosão Mandibular (p ≤ 0.001).
Conclusões: Concluiu-se que a prevalência de desgaste erosivo foi bastante elevada
neste estudo, no entanto este não está relacionado com idade nem género dos pacientes.
Parece haver uma relação entre os níveis de desgaste na arcada superior e inferior, que
deve ser estudada mais aprofundadamente em estudos futuros.
Objectives: This study evaluated the prevalence and distribution of erosive dental wear in patients from Clínica Universitária Moniz (CUEM). Material and Methods: Approval was obtained from the Ethics Committee of Egas Moniz. The sample of the study consisted of 50 patients from CUEM, randomly selected, who gave their informed and signed consent to participate. The erosive tooth wear was evaluated using the Lussi Index. All participants were evaluated by the same observer, after calibration with an experienced observer. This calibration was performed with 10 randomly selected patients from CUEM, who were separately evaluated by the 2 observers, and the level of agreement of calculated by the Cohen’s kappa value. The correlation between the dependent variables “Total Erosion”, “Maxillary Erosion”, “Mandibular Erosion” and “Anterior Wear”, which were calculated from the Lussi classification, and the independent variables “Age” and “Gender”, were statistically analyzed. Results: A prevalence of 90% was found for Total Erosion. No statistically significant association was found for either Age and Total Erosion (p = 0.766) nor for Gender and Total al Erosion (p = 0.385). However, a statistically significant association was found between the distribution of erosive wear levels in the maxilla and mandible (p = 0.007), as well as between Total Erosion and Maxillary Erosion (p ≤ 0.001) and Total Erosion and Mandibular Erosion (p ≤ 0.001). Conclusions: A high prevalence of Total Erosion was found for this patient sample, however no relationship could be found with either Age nor Gender. Apparently the erosive wear in the maxilla and mandíbula are related to each other, but this relationship needs to be further investigated.
