Abstract

Aim: To compare the effectiveness of self-examination, clinical examination and screening methods using 1% toluidine blue and Lugol's iodine in estimating the prevalence of lesions at risk of malignancy and oral malignant disease amongst the male inmates of Yerwada Central Jail, Pune. Material and Methods: Study was carried out on male inmates in two phases. In the first phase self-examination and clinical examination was carried out on 2,257 male inmates. 164 suspicious cases were subjected to phase II of the study out of whom, 82 participants were screened with 1% toluidine blue and 2% Lugol's iodine followed by biopsy procedure. Results: Sensitivity and specificity for self-examination with clinical examination was 92.2% and 96.6% respectively. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) and positive (+LR) and negative likelihood ratio (-LR) for Toluidine Blue were 88.1%, 66.6% 97.1%, 30%, 2.63 and 0.17 respectively while for Lugol's Iodine they were 94.7%, 83.8%, 98.6%, 55.5%, 5.67 and 0.06 respectively. Conclusions: Prevalence of lesions at risk of malignancy and oral malignant disease by self-examination was 7.8% and by clinical examination was 6.3%. Self-examination is an effective tool in early detection of oral cancer. Use of Lugol's iodine as a screening tool for oral lesions is highly effective in inmate populations.
