Comparative effectiveness of chewing stick and toothbrush: a randomized clinical trial

With the increasing rate of oral diseases, the global necessity of effective and economical products for its prevention and treatment has intensified.

THIS STUDY WAS TO COMPARE THE EFFECTIVENESS OF TWO ORAL HYGIENE AIDS: Chewing stick and manual toothbrush, for plaque removal and gingival health after one month of a randomized clinical trial.

Dental students (age 18-22 years) of a public sector dental hospital were recruited. Sample size was determined using the American Dental Association guidelines. Participants were randomized into two interventional groups and provided with either chewing sticks or toothbrushes. Pre- and post-intervention examinations were executed by two blind and calibrated examiners using plaque and gingival dental indices. Statistical analysis included descriptive statistics, paired t-test, and two sample independent t-tests.

Fifty subjects were recruited with mean age 20 ± 0.66 years (80% were females and 20% were males). Except for the mean plaque scores of toothbrush users (which increased at post-intervention examination), all other scores showed reduction. In contrast to the final mean gingival scores, a significant difference (P = < 0.0001) in the final mean plaque score was observed for the two respective interventional groups.

Chewing stick has revealed parallel and at times greater mechanical and chemical cleansing of oral tissues as compared to a toothbrush.
