BMI was evaluated by measuring subjects weights and height. Simplified oral hygiene index (OHI-S) was determined by GreenVermillion. The data gained was analyzed by using chi-square and its correlation is determined by contingence coefficient. Result. statistical test result shows that t-value (6, 793) < t-table (12, 592) which means there is no relationship between BMI with OHI-S. The contingency coefficient test gives the result of C=0, 177 which is belong to interval of 0.00< C < 0.25 identifying that the correlation between BMI and OHI-S is included in degree of weak association.
