Background: Microbiological plaque is the main etiological factor in the development of periodontal diseos Regular and effective removal of plaque from all surfaces of the teeth is essential for the prevention of the^ diseases.

The purpose of this study was to compare the plaque removal effectiveness of a battery powered and manual toothbrush by using plaque index and to compare differences in pocket depth and gingival index between the two groups over a 3-months period.

Material and methods: This study was randomized controlled and examine-blind designed.

Forty patients were included in the study, all'the subjects were non smokers male and they were stratified and randomized to one of the two brushing groups.

A total of 5 visits were planed for data recording, the clinical parameters include: - plaque index, gingival index, probing pocket depth.

Results Significant and highly significant differences was found for both groups during the study according to the Mest in PI and Gl, Also significant difference was found between the two groups in favor of manual tooth brush.

The longitudinal changes in pocket depth show significant and highly significant difference from the base line in the both groups and using f-test but No statistical difference was detected between the batteries powered brushing and manual brushing groups in the outcome measure of PD at any time point during the study.

Conclusion According to the results obtained both toothbrushes' mean difference between baseline and post-brushing plaque scores decreased.

Manual tooth brush plaque removal was more efficient in comparison to battery powered toothbrush also gingival health shows more improvement with manual tooth brush when compared with battery powered tooth brush; no significant difference in pocket depth was found with both types of tooth brushes.
