Plaque scores were determined at baseline, three and six months using the Turesky-Gilmore-Glickman Index. Likewise, gingival indices were determined using the Loe Silness Gingival Inflammation Index.
Group 1 (test) showed a 36.17% reduction in plaque from baseline to month six, compared to only 18.56% for the control group. Improvement in gingival health was 51.87% for the test group and 30.18% for the control group. The average changes in both plaque and gingival indices were statistically significant for the test group using the hyG IONIC toothbrush with an active battery.
The toothbrushes were identical except for the presence of the active battery. The ionic action from the three (3) volt lithium battery produced the significant plaque and gingival changes observed.
The Hukuba hyG IONIC toothbrush is a safe and effective oral cleansing device when used unsupervised on a regular basis in the removal of human dental plaque.
PLAQUE REMOVAL EFFECTIVENESS OF IONIC TOOTHBRUSH EMPLOYING THE LITHIUM BATTERY
Results:
-
Plaque removal. Estimates according to O'Leary's PCR (p<0.01) and PHP (p<0.05), the efficacies of the lithium battery toothbrush and the control toothbrush differed significantly.<0.01) and PHP (p<0.05), the efficacies of the lithium battery toothbrush and the control toothbrush differed significantly.
-
Improvements in gingivitis. In terms of the PMA index (p<0.05), the lithium battery toothbrush produced better results than the control toothbrush.<0.05), the lithium battery toothbrush produced better results than the control toothbrush.
-
Changes in bacterial levels. No changes in oral microorganism levels were observed after the experimental period, no matter which kind of toothbrush was used.
-
Plaque accumulation compared in terms of caries risk group. In the Low risk group, no significant differences were observed between the toothbrushes before and after the experimental period. In the High risk groups, however, the lithium battery toothbrush removed bacterial plaque more effectively.
