Objective: Cerebral palsy (CP) is a postural syndrome and nonprogressive motor disorder due to pyramida and extrapyramidal tract damaged that causes limited motor activity and often accompanied by cognitive impairment or visual deficits. Limited motor activity causes the process of brushing teeth to be hampered so that oral hygiene becomes low. Nowadays there many types of toothbrushes that required difficult motor activities so it is not effective for children with CP. Wall Mounted Automatic Toothbrush with an automation system es expected to help CP children maintained their oral hygiene. Material and Methods: This study was clinical experimental with one group pretest posttest design in 5 samples in SMPLB and SMALB D YPAC Jember. Data analysis was the One Way Anova and Post-Hoc test using the Least Significat Diffferent. The Material of this study is wall mounted automatic tootthbrush and manual toothbrush, both of them is used by children with cerebral palsy Results: There are significant differences between all treatment groups. The lowest of Silness and Loe plaque index of all treatment groups is the treatment group after brushing teeth with manual toothbrush. Conclusion: The conclusion of this study is wall mounted automatic toothbrush can improve oral hygiene measured by the Silness and Loe plaque index.
