ABSTRACT

Abstract Panoramic radiographs (PR) can display radiopaque images suggestive of calcified atheroma in the carotid artery in asymptomatic patients. The aim of this study was to evaluate the prevalence of these images on PR and their linkage with hypertension, obesity, age, gender and smoking habits. PR of 505 patients were evaluated. They were older than 30 years old and their PR had been taken for different clinical reasons. Their body mass index was calculated; their waist circumference was also taken into consideration. Information about smoking habits and hypertension was obtained. The observers analyzed the presence of radiopaque mass in the region of the cervical vertebrae C3-C4 through the PR, confirmed by an antero-posterior (AP) radiograph. The results showed a 7.92% prevalence of suggestive images of calcifications on PR and on AP radiograph. The adjusted Odds Ratio showed association with age and smoking habits. The calcification process is almost nine times higher for the elderly when compared to the young. As far as smokers are concerned, this process is twice worse when compared to no smokers. In conclusion, 7.92% of the group studied presented suggestive images of carotid atherosclerosis on PR, which is directly associated with the age and smoking habits.


Resumo As radiografias panorâmicas (RP) podem exibir imagens radiopacas sugestivas de ateromas calcificados na artéria carótida em pacientes assintomáticos. O objetivo deste estudo foi avaliar a prevalência destas imagens na RP e sua relação com hipertensão, obesidade, idade, sexo e tabagismo. Foram avaliadas RP de 505 pacientes acima de trinta anos, que realizaram esse exame por diversos motivos clínicos. Seu índice de massa corpórea foi calculado; sua circunferência abdominal também foi considerada. Informações sobre hipertensão e tabagismo foram obtidas. Os observadores avaliaram as RP para a presença de massas radiopacas na região das vértebras cervicais C3-C4, confirmadas por meio de uma radiografia ântero-posterior (AP). Os resultados mostraram prevalência de 7,92% de imagens sugestivas de calcificações em RP e na radiografia AP. A razão de probabilidade (OR) ajustada mostrou associação com idade e tabagismo. O risco para as pessoas mais velhas aumenta até cerca de nove vezes quando comparado com aqueles mais jovens, enquanto para os fumantes, o risco é o dobro, quando comparado com não fumantes. Na população estudada, 7,92% de todos os sujeitos apresentaram imagens sugestivas de aterosclerose carotídea em RP e houve associação com idade e tabagismo.
