Abstract

Patients with fixed orthodontic appliances frequently have increased levels of plaque accumulation leading to the possibility of gingivitis or enamel decalcification. Although many methods may be helpful in reducing dental plaque formation, the optimal mechanical removal of plaque is the most important factor during orthodontic treatment. The purpose of this study was to evaluate the efficacy of an electric toothbrush (with a specially designed orthodontic brush head) compared to a manual toothbrush in controlling plaque and gingivitis for patients with fixed orthodontic appliances. Oral hygiene status was measured in thirty-four patients using a plaque index, a gingival index and a bleeding index, before and four weeks after the attachment of fixed orthodontic appliances. Patients were randomly divided into two groups: electric and manual toothbrush groups. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B D9511 with Braun Oral-B Ortho OD 15-1 brush head was used as the electric toothbrush while the Butler G.U.M. 124 was given as the manual toothbrush. After four md eight weeks, oral hygiene status was measured again. Through a comparison between the electric and the manual toothbrush groups, the following results were obtained. 1. All oral hygiene indices showed an increasing tendency after four weeks of fixed orthodontic appliance. 2. All indices presented a decreasing tendency four and eight weeks after oral hygiene instruction. 3. In case of the gingival index and bleeding index, the decreasing tendency did not show a statistically significant difference between the electric and the manual toothbrush groups. 4. The decreasing tendency of plaque index presented a statistically significant difference between the two groups, showing that the electric toothbrush was more effective in terms of oral hygiene. These findings suggest that an electric toothbrush is useful to orthodontic patients with fixed appliances.

고정식 교정장치를 부착한 경우 장치주위의 치태 축적 가능성이 증가되고 이로 인해 치은염, 법랑질 탈회 등의 부작용이 초래 될 수 있는 바 치태 제거를 위한 효과적인 칫솔질이 필요하다. 본 연구는 교정환자에서 일반적으로 사용되고 있는 치솔에 비하여 전동치솔이 구강위생에 도움이 되는지 알아보기 위하여 시행되었다. 고정식 장치에 의한 교정치료 예정인 환자 34명을 본 연구의 대상으로 하여 고정식 교정장치 부착 전에 치태지수, 치은염지수, 치은출혈지수를 측정하였다. 장치 부착 4주 후에 각 지수를 측정한 다음, 연구대상을 치솔의 종류에 따라 전동치솔군과 수동치솔군으로 임의 구분하여 수동치솔 또는 전동치솔을 사용하도록 구강위생교육을 각각 시행하였다. 이때 전동치솔의 경우 본체는 Braun Oral-B D9511을 브러쉬 헤드는 Braun Oral-B Ortho OD 15-1을 사용하게 하였으며, 수동치솔의 경우는 Butler G.U.M 124를 사용하게 하였을. 구강위생교육 4주 및 8주 후에 각 지수를 측정한 다음 시간 경과에 따른 전동치솔군과 수동치솔군의 구강위생 상태를 비교 분석하여 다음과 같은 결과를 얻었다. 1. 고정식 교정장치 부착 4주 후 치태지수, 치은염지수, 치은출혈지수 모두 증가 양상을 나타내었다. 2. 구강위생교육 후 치태지수, 치은염지수, 치은출혈지수 모두 감소 양상을 나타내었다. 3. 치은염지수, 치은출혈지수의 경우 감소양상이 수동치솔과 전동치솔군 간의 유의한 차이를 보이지 않았다. 4. 치태지수의 경우 수동치솔에 비해 전동치솔군에서 감소효과가 유의하게 크게 나타났다. 이상의 연구 결과는 고정식 교정장치로 치료받는 환자에서 전동치솔이 구강위생에 도움이 됨을 시사하였다.
