| Popis: | 93 Background: Although “Modified Bass method”had been promoted by China Dental Association for many years for schoolchildren who could learn correct method of toothbrushing. But the pattern of change-hand operation is too complicated and hard for children to learn this method. Teachers should make more effort to let children understanding with which hand to brush which part of teeth. It will be better choice if we could simplify the way of change-hand and keeping the same benefit. Study purposes: The purposes of this research were to design an improvement of “modified Bass method”, Which can be applied to educational curriculum on 4th grade children of primary school, and to investigate the different result with the standard method. Methods: There were 131 schoolchildren of 4th grade from the same primary school at the downtown of Kaohsiung City. The experiment group had 64 schoolchildren, and the control group had 67 schoolchildren. At the first stage, schoolchildren in both groups finished pre-test dental plaque index, control group had modified Boss method curriculum; the experimental group accepter the“Improved Boss method”intervention. There were 2 classes (40 min each ) for both groups, and received post-test plaque count record (PCR). The statistical analyses were performed by JMP5. Results: 1. It was found that the full mouth score changes on plaque index (0.09±20, P-value=0.0091) from pre- to post-test were statistically significantly better in the experiment group. 2. In the arrears where is easily brushing for example buccal side of upper-central incisor＆posterial-left teeth, there was no difference for both groups. But in the area where is not so convenient cleansing, for example lingual side of right-upper posterial teeth and lower incisors. PCR improvement of experiment group were statistically significantly better that the control group. Conclusion: The plaque index was improved significantly after fist intervention of the Improved Bass-method. But the modified method even getting worse. It means that Improved method is easier accepted by schoolchildren, it’s more effective toothbrushing method for oral health promotion. |
