Abstract: The research aimed to study the effect of mouthwash on the genetic damage of root tip cells of garlic, different concentrations of mouthwash were used separately to treat the root tip of garlic for 8, 12 and 24 h. The results showed that mouthwash induced the aberration of chromosomal and nuclear, the higher concentrations of mouthwash induced higher frequency of micronucleus rates(P<0.05). while he number of mitosis cell of divisions and mitotic index decreased(P<0.05), which were negatively correlated with the treatment time and dose of mouthwash. These results suggested mouthwash caused the genetic damage.

Key words: mouthwash, micronucleus rate, micronucleus index, mitotic index
