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 on the periodontal health of patients with fixed orthodontic appliances Forty patients were randomly divided into two groups. the electric and the manual toothbrush groups, 1 month after attachment of fixed orthodontic appliances. Periodontal status was measured using a plaque index, a gingival index. a bleeding index, a pocket depth and a relative attachment loss, at baseline and after 3 months. 6 months, 9 mouths. and 12 mouths. The Braun Oral-B Plak Control with 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. In the manual toothbrush group, the giugival and bleeding indices showed no statistically significant differences, but the plaque index was significantly decreased (P<0.001) and pocket depth as well as relative attachment loss were significantly increased (p<0.01). In the electric toothbrush group. the bleeding index, pocket depth and relative attachment loss showed no statistically significant differences. but the plaque and gingival indices were significantly decreased (p<0.001). In the case of the plaque. giugival and bleeding indices, there were no statistically significant differences between the electric and the manual toothbrush groups. On the contrary, in the case of pocket depth and relative attachment loss, there were statistically significant differences between the electric and the manual toothbrush groups: an increase in the manual toothbrush groups unlike the electric toothbrush group which kept the same state (P<0.05) These findings suggest that an electric toothbrush is useful for orthodontic patients with fixed appliances.

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.

Purpose: The purpose of this study was to evaluate the antimicrobial effects of a toothbrush with light-emitting diodes (LEDs) on periodontitis-associated dental biofilm attached to a zirconia surface by static and dynamic methods. Materials and Methods: Zirconia disks (12 mm diameter, 2.5 mm thickness) were inserted into a 24-well plate (static method) or inside a Center for Disease Control and Prevention (CDC) biofilm reactor (dynamic method) to form dental biofilms using Streptococcus gordonii and Fusobacterium nucleatum. The disks with biofilm were subdivided into five treatment groups-control, commercial photodynamic therapy (PDT), toothbrush alone (B), brush with LED (BL), and brush with LED+erythrosine (BLE). After treatment, the disks were agitated to detach the bacteria, and the resulting solutions were spread directly on selective agar. The number of viable bacteria and percentage of bacterial reduction were determined from colony counts. Scanning electron microscopy (SEM) was performed to visualize alterations in bacterial morphology. Results: No significant difference in biofilm formation was observed between dynamic and static methods. A significant difference was observed in the number of viable bacteria between the control and all experimental groups (P < 0.05). The percentage of bacterial reduction in the BLE group was significantly higher than in the other treated groups (P < 0.05). SEM revealed damaged bacterial cell walls in the PDT, BL, and BLE groups, but intact cell walls in the control and B groups. Conclusion: The findings suggest that an LED toothbrush with erythrosine is more effective than other treatments in reducing the viability of periodontitis-associated bacteria attached to zirconia in vitro.

치아의 건강은 오복중의 하나라고 할 만큼 우리에게 소중한 신체기관이다. 치아가 건강하지 않다면 인생사의 즐거움 중의 하나인 '먹는 즐거움'을 누릴 수가 없다는 것은 부연의 여지가 없다. 그러나 갖가지 다양한 음식물과 여러 가지 질병들, 그리고 우리 자신의 소홀함 등으로 인해 치과질환을 앓는 사람들은 경제성장의 속도와 비례해서 날로 증가하고 있다. 예로부터 깨끗한 이, 고른 이는 미인의 조건이라고 얘기되어져 왔다. 이것은 타고 나는 복일 수도 있지만, 생활 속에서 조금이라도 더 관심을 가지고 관리해 나가는 것이 자신의 건강을 위해서도 좋겠고, 많은 사람들을 상대해야 하는 오늘날 사회생활의 예의이기도 할 것이다.
