Abstract(s)
Este trabalho teve como objetivo estudar a prevalência e distribuição de desgaste dentário erosivo numa amostra de pacientes da Clínica Universitária Egas Moniz (CUEM).
Para este estudo piloto, descritivo e transversal, foi selecionada aleatoriamente uma amostra de 50 pacientes, com idades compreendidas entre os 20 e os 44 anos. O desgaste dentário erosivo foi avaliado, sempre pelo mesmo observador, usando o índice BEWE (Basic Erosive Wear Examination). Foi realizada previamente uma calibração do observador com um observador experiente na área, para o uso do índice. Para tal foram observados separadamente, pelos dois observadores, 10 pacientes da mesma clínica, também selecionados aleatoriamente, e calculou-se o nível de concordância 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”.
Encontrou-se uma prevalência de 92% de Erosão Global na amostra estudada. Não se verificou uma associação estatisticamente significativa tanto para as variáveis Idade e Erosão Global (p = 0.652) como para Género e Erosão Global (p = 0.408). Da mesma forma, não foi encontrada uma relação estatisticamente significativa entre o Desgaste Anterior e a Erosão Global (p = 0.433) nem entre o Desgaste Anterior e a Idade (p = 0.617). Pelo contrário, foi observada uma correlação significativa entre a distribuição dos níveis de desgaste erosivo na maxila e na mandíbula (p = 0.002), bem como entre a Erosão Global e as variáveis Erosão Mandibular (p ≤ 0.001) e Erosão Maxilar (p ≤ 0.001). Já no que diz respeito à correlação das variáveis Desgaste Anterior e Género (p ≤ 0.001), foi encontrada igualmente uma associação estatisticamente significativa.
Concluiu-se que a prevalência de desgaste dentário erosivo global, na amostra estudada, embora elevada, não apresenta relação com a idade, o género ou com o desgaste anterior.
The aim of this study was to estimate the prevalence and distribution of erosive tooth wear in a sample of patients from Clínica Universitária Egas Moniz (CUEM). A sample of fifty randomly selected patients, aged 20 to 44 years old, were examined using the Basic Erosive Wear Evaluation index (BEWE) by the same observer. Prior to the study, the observer was calibrated with an experienced observer, by examining separately 10 randomly selected patients from CUEM, and the Cohen’s kappa was calculated. The correlation between the dependent variables “Total Erosion”, “Maxillary Erosion”, “Mandibular Erosion” and “Anterior Wear”, which were calculated from the BEWE classification, and the independent variables “Age” and “Gender”, were statistically analyzed. A prevalence of 92% was found for Total Erosion. A non-statistically significant association was found for Total Erosion and Age (p = 0.652) and Total Erosion and Gender (p = 0.408). Similarly, no statistically significant relationship was found between Anterior Wear and Total Erosion (p = 0.433) nor between Anterior Wear and Age (p = 0.617). On the contrary, a significant correlation was observed between the distribution of erosive wear levels in the maxilla and mandible (p = 0.002), as well as between Total Erosion and the variables Mandibular Erosion (p ≤ 0.001) and Maxillary Erosion (p ≤ 0.001). Regarding the correlation between the variables Anterior Wear and Gender (p ≤ 0.001), a statistically significant association was also found. It was concluded that the prevalence of erosive wear, in this group of patients, was relatively high, and seemed not to be related to age, gender or wear in the anterior teeth.
