Aim
Streptococcus mutans has been detected as one of the most invasive microbial pathogens in oral disease. The aim of the present study is to evaluate the antimicrobial potential of 980 nm diode laser against S. mutans species.
Method
In this in vitro study, ATCC 10,662 strain of Streptococcus mutans was provided, incubated, and then cultured in blood agar. The specimen was divided randomly into 5 groups, one control group and four experimental groups with 1, 1.5, 2, and 3 w output power respectively. Antimicrobial surveillance was evaluated by a microtube test, and the resulted data were analyzed using SPSS 22.0 and with 0.05 significance.
Results
The results of the following study showed that the average and minimum growth rate of the groups was the same (100 w) but the maximum rate of growth was 0 in the 1.5 w group which was lower than the other groups (100 w). The difference between groups was not statistically significant (p = 0.722).
Conclusion
The findings of the following study suggested that using 980 nm diode laser could not significantly reduce S. mutans growth rate, so it is suggested to perform further investigations with more equipment and further modalities.
