Objective: In order to compare the dental plaque removal effect on the proximal area and around the bracket for orthodontic dental patient between by using the electric interdental brush and by using the manual one.
Methods: Electric interdental brush was designed and developed by Industry and Academy Co-Operation Center of Honam University on December in 2018, and used it as experimental group and the manual interdental brush which was the similar shaped of the brush head with the electric one was used as a control group. Fifty times of tooth-brushing at the proximal side and around the bracket was done with use of two kinds of interdental brushes at the right side and left side for a patient, in order to compare the plaque removal effect after using them after checking of the residual plaque.
Results: The comparison of the removal amounts of the dental plaque by use of two types of interdental brush. 3 Electric 30 3.79±3.08, 3 Manual 30 1.10±0.24 5 Electric 30 4.92±5.46, 5 Manual 30 1.36±0.51.
Conclusion: Electric interdental brush which was developed for the experiment was effective to remove the dental plaque at the proximal side and around the bracket for the orthodontic dental patient, and recommended to use for fixed typed orthodontic dental patient in clinical.
