Oral cancer is a public health problem responsible for 13% of deaths worldwide in 2008 and screening programs can be useful to detect individuals more vulnerable to the disease, improving its prognosis.
The aim of the present study was to evaluate oral cancer calibration (in lux and in vivo methodologies) and diagnosis processes performed by dental surgeons (DSs) of the public health system in São Paulo, Brazil.
Thirty-three oral cancer photographs were examined during in lux calibration, while 560 individuals were examined during in vivo calibration. Oral conditions were coded as "0 - sound tissues", "1 - buccal lesions without malignant potential" and "2 - buccal lesions with malignant potential". The final sample for oral cancer screening was composed of 336 individuals, age-range 40 years or older.
Kappa values for interexaminer agreement were 0.67 and 0.45 for in lux and in vivo respectively. The accuracy of both methodologies was over 80%. Oral cancer screening revealed 48 healthy individuals, 273 oral lesions coded as "1" and 12 oral lesions coded as "2".
In spite of the low reproducibility, the validity of the visual examination in oral cancer screening was satisfactory, showing its importance as part of preventive oral cancer programs and public health system campaigns.
口腔癌是一个公共卫生问题，在2008年占全球死亡人数的13%，筛查项目有助于发现更易患该病的个体，改善其预后。
本研究旨在评估巴西圣保罗公共卫生系统的牙科医生（DSs）进行的口腔癌校准（在光照条件下和活体方法）及诊断过程。
在光照校准期间检查了33张口腔癌照片，在活体校准期间检查了560名个体。口腔状况被编码为“0 - 健康组织”、“1 - 无恶性潜能的颊部病变”和“2 - 有恶性潜能的颊部病变”。口腔癌筛查的最终样本由336名年龄在40岁及以上的个体组成。
光照校准和活体校准的检查者间一致性的Kappa值分别为0.67和0.45。两种方法的准确率均超过80%。口腔癌筛查发现48名健康个体、273个编码为“1”的口腔病变和12个编码为“2”的口腔病变。
尽管重复性较低，但视觉检查在口腔癌筛查中的有效性令人满意，表明其作为预防性口腔癌项目和公共卫生系统活动一部分的重要性。
