The mean OHI-S and oral health knowledge scores were compared and evaluated using the parametric t-test for dependent samples. Oral hygiene before education score was 2.04 ± 0.77 and improve after education score was 1.37 ± 0.59 (p = 0.00, 95% CI). Oral health knowledge before education score was 63.8 ± 1.28 and increased after education score was 83.8 ± 1.09 (p = 0.00, 95% CI). The oral
