Abstract

Objective: To evaluate the effects of an electric toothbrush with vibrational frequencies of 125 Hz and 150 Hz on the orthodontic tooth movement (OTM) rate and the production of prostaglandin E2 (PGE2).

Methods: Out of thirty patients (aged 18-25 years; 16 females and 14 males), ten patients each formed Group A and B, who used electric toothbrushes with 125 Hz and 150 Hz vibrations, respectively. The remaining ten patients (Group C) served as the control group and did not use electric toothbrushes. The rate of OTM and levels of PGE2 using microcapillary pipettes were calculated before the start of retraction (T0), on the 30th day (T1), on the 60th day (T2), and on the 90th day (T3) from the start of retraction in all the groups.

Results: There was a statistically significant difference in the mean OTM values and PGE2 levels in all three groups at different time intervals, with the maximum difference seen in Group B compared to Group A and least in Group C at T1, T2 and T3.

Conclusions: The rate of OTM and levels of PGE2 were highest in patients who used an electric toothbrush with 150 Hz mechanical vibration compared to those who used an electric toothbrush with 125 Hz mechanical vibration and least in patients who did not use an electric toothbrush. Mechanical vibration led to an increase in the PGE2 levels and accelerated the OTM.

125Hz和150Hz振动频率电动牙刷对正畸牙齿移动速率和前列腺素E2水平的影响。

目的：评价125Hz和150Hz振动频率的电动牙刷对正畸牙齿运动（OTM）速率和前列腺素E2（PGE2）产生的影响。方法：在30名患者（年龄18-25岁；16名女性和14名男性）中，10名患者分别组成A组和B组，分别使用125 Hz和150 Hz振动的电动牙刷。其余10名患者（C组）作为对照组，不使用电动牙刷。使用微毛细管移液管在所有组的回缩开始前（T0）、第30天（T1）、第60天（T2）和第90天（T3）计算OTM的速率和PGE2的水平。结果：三组在不同时间间隔的平均OTM值和PGE2水平均存在统计学显著差异，其中B组与a组相比差异最大，C组在T1时差异最小，结论：与使用125Hz机械振动电动牙刷的患者相比，使用150Hz机械振动的电动牙刷的OTM发生率和PGE2水平最高，而不使用电动牙刷的病人OTM和PGE2含量最低。机械振动导致PGE2水平升高并加速OTM。

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
