Thực trạng viêm lợi và độ nhạy, độ đặc hiệu của chẩn đoán viêm lợi qua ảnh chụp bằng điện thoại smartphone trên học sinh 15 tuổi tại Hưng Yên

Abstract

The objective was to describe the prevalence of gingivitis and determine the sensitivity and specificity of gingivitis through smartphone images compared to clinical examination in 15 years old students. A cross-sectional study was conducted on 404 students selected randomly from 4 secondary schools in Hung Yen. We conducted clinical examination and oral imaging to diagnose gingivitis and classify according to the gingival index. Prevalence of gingivitis from the clinical examination was 83.7% and mostly in grade I (GI), 57.4%. Smartphone images had the sensitivity and specificity in diagnosing gingivitis, at 97.0% and 42.4%, with the accuracy of 88.1%. The level of agreement between the two diagnostic methods was moderate (Kappa=0,48). The prevalence of Grade I (GI) gingivitis in 15 year-old students in Hung Yen is high at 83.7% . The sensitivity and accuracy of smartphone images in the diagnosis of gingivitis are high and acceptable. However, the specificity is low. Dentists can use smartphone photographs to selectively diagnose gingivitis in 15 years old children, prioritizing in areas with high incidences.
