THE EFFECTIVENESS OF TOOTH BRUSHING WITH BASS AND ROLL METHOD ON DECREASIN PLAQUE INDEX IN DEAF STUDENTS

Abstract

ABSTRACT. The cause of plaque is caused by an unclean mouth and teeth. For example, the case
experienced by deaf students at SDLB-B Karya Mulia Surabaya has a poor category plaque index of
3.55. This case tends to be experienced by children with special needs because they do not
understand well the correct tooth brushing methods so that the condition of the mouth and teeth
can remain clean. The objective of the research is to ascertain the effectiveness of different tooth
brushing methods for reducing the plaque index in deaf students at SDLB-B Karya Mulia Surabaya.
The sample data implemented in the research is deaf students at SDLB-B Karya Mulia Surabaya aged
9-12 years with a total of 50 students. Then the students will be divided into two groups, where each
group will be tested quasi-experimentally through the application of pre-test and post-test.
Furthermore, the measurement of plaque index both after and before brushing teeth by
implementing the Podshadley and Haley method. The results of this study showed a reduction in
plaque index within both groups before and after brushing using both methods. The observed
results, with a significance value of 0.344 (2-tailed), suggest that there is no significant difference
between the two groups in terms of the effectiveness of brushing teeth in reducing the plaque
index. Brushing teeth with bass and roll methods shows the same effectiveness in decreasing the
plaque index.
