description <i>Background and Objectives</i>: The aim of this study was to compare the effects of low-level laser therapy and continuous microwave diathermy on the growth of Gram-negative and Gram-positive bacteria and to establish their efficacy as an alternative therapeutic modality. <i>Materials and methods</i>: Laser fluence of 13 Joules (J)/cm<sup>2</sup>, 18 J/cm<sup>2</sup> and 30 J/cm<sup>2</sup> were used against several bacterial strains. Microwave dosages of 25, 50 and 100 watts (W) were used, respectively. <i>Results</i>: A significant difference between the three groups was observed using repeated analysis of variance (RANOVA) (F value: 0.74, and <i>p</i> value: 0.001). The Greenhouse&#8722;Geisser correction (GG) revealed significant results for laser irradiation alone. However, effect size calculation showed effects with microwave diathermy as well as laser fluence. <i>Conclusions</i>: Low-level laser therapy appears to be an effective modality of treatment when compared with continuous microwave diathermy on the Gram-negative and the Gram-positive bacterial strains tested. Microwave diathermy revealed large and medium effects on the bacterial cell counts with dominant effects on Gram-negative strains.
