Effectiveness of Chewable Tooth Brush in Children-A Prospective Clinical Study

Dental plaque is one of the aetiological factors in causation of dental caries. Effective removal of plaque can reduce the incidence of caries. Various agents for removing plaque has been introduced, of which, chewable brush is a recent advance. There is limited evidence assessing the effectiveness of using chewable brush in children.

The aim of this study was to evaluate the effectiveness of chewable brush in relation to efficiency in plaque removal and reduction in S.mutans counts in saliva.

Ten children of six-nine years with their first molars erupted were included in the study and the children were supervised for their normal brushing for 7 days. The baseline Oral Hygiene Index-Simplified (OHI-S), Plaque Index (PI) and Decay, Missing Filled Tooth Index (DMFT-I) were noted and the saliva sample was collected from the children. The sample was sent for microbiological examination of S.mutans count and the pH of the saliva was also determined. The children were advised to brush their teeth twice daily for seven days using chewable brush. On the seventh day, the indices were noted again and the saliva sample was collected and sent for microbiological examination. Statistical analysis was done using paired t-test to compare the pre and post-brushing index scores, S. mutans count and salivary pH.

There was a significant reduction in the debris index (p<0.001), oral hygiene index (p<0.000), plaque index (p<0.001), pH of the saliva (p<0.037) and S. mutans level (p<0.006) before and after brushing with chewable brush. However, the calculus index remained unchanged (p=0.168).

Chewable brush can be used as an effective alternative to manual brushing in children.
