OBJECTIVES: This study aims to assess the difference in microbial contamination of a toothbrush with a smooth handle versus a toothbrush with a grooved handle design. METHODS: Twenty-six volunteers were randomized into two groups. The first group used a smooth handle toothbrush for two months, followed by a grooved handle toothbrush for two months. The second group had the order reversed. Following the two-month use, the toothbrushes were submitted for microbial analysis. Effect size, as well as Wilcoxon signed-rank test were used to calculate the differences between total colony count, bacterial DNA, and endotoxin levels from the two toothbrush handle types. RESULTS: There was no significant difference in colony count between the smooth (mean 580 CFU/mL, SD 1,684 CFU/mL) and grooved (mean 19,059 CFU/mL, SD 80,972 CFU/mL) handles (p = 0.12). Total DNA count was significantly less (p = 0.01) on the smooth handle (mean 68,038 RFU/mL, SD 81,659) compared to the grooved handle (mean 209,312 RFU/mL, SD 257,169 RFU/mL). Endotoxin levels were significantly less (p = 0.01) on the smooth handle (mean 0.16 EU/mL, SD 0.30 EU/mL) compared to the grooved handle (mean 0.43 EU/mL, SD 0.49 EU/mL). CONCLUSIONS: The smooth handle toothbrush had significantly less bacterial contamination compared to the grooved handle toothbrush, as measured by total DNA count and endotoxin levels.
