All patients did not receive antibiotics for three days at less, to state the relationship between gender, smoking, miswak, toothpaste, milk and sugar with black tea with gingivitis. Streptococcus mutans was isolated with 100%. S. mutans was isolated with 75% from males and 25% from females depending on the morphological and biochemical tests.
