Effectiveness of electric toothbrush as vibration method on orthodontic tooth movement: a split-mouth study

Abstract

Objective: To investigate the effects of application of vibratory stimuli, using an electric toothbrush, on the rate of orthodontic tooth movement during maxillary canine retraction. Methods: A split-mouth study was conducted in 28 subjects (mean age = 20.8 years; ranging from 18 to 24 years) whose bilateral maxillary first premolars were extracted with subsequent canine retraction. On the Vibration side, light force (100 g) was applied to the canine for 90 days, in combination with vibratory stimuli provided by an electric toothbrush; only orthodontic force was applied to the canine on the non-vibration side. Amount of canine movement was measured monthly. Related to electronic toothbrush usage, a diary was provided to each patient for recording discomfort during experimental period, having 100-mm visual analogue scale (VAS). The paired t-test was used to assess the differences in amount of tooth movement between canines of the vibration and non-vibration sides. Results: The amount of tooth movement was similar for canines on the vibration side and on the non-vibration side (mean 0.81 ± 0.10 mm and 0.82 ± 0.11 mm, respectively, p> 0.05). Plaque accumulation was minimal in any subject throughout the study. No subject reported discomfort as a result of using the electric toothbrush. Conclusions: This study demonstrates that application of vibratory stimuli using an electric toothbrush, in combination with light orthodontic force, do not accelerate orthodontic tooth movement.

“…Another alternative device for providing vibration therapy are the electrical toothbrushes. Following electrical toothbrushes can be used for this purpose  Electrical toothbrushes (Hamming Bird, Oral B, Braun, P&G company, Cincinnati, Ohio, USA)-113 Hz for 10min/day (RCT by Liao et al [9] They were considered clinically beneficial)  Electrical toothbrushes (Colgate Motion-Multi Action, Colgate-Palmolive Company, New York, USA)-125 Hz for 15min/day (RCT by Leethanakul et al [10] Vibratory stimuli increased tooth movement)  Electrical toothbrushes (Oral-B Triumph, OD17; P&G company, Cincinnati, Ohio, USA)-125 Hz for 20min/day (RCT by Azeem et al [11] Vibrations generated did not accelerate tooth movement) Mao was the inventor of the concept behind vibrating force to enhance and accelerate tooth movement [12] . In a monkey model, tooth movement rates up to 40% faster were demonstrated in response to vibration as early as 1986 by Shimizu et al [13] H. Utomo (Airlangga University) has suggested via literature search that patients who regularly chews gum (a crude form of vibratory force application) exhibit accelerated rates of tooth movement.…”

Analysis of Cosmetic Effect of Nanocomposite Resin on Anterior Teeth

“…Note that the CPI probe should be used with a force of less than or equal to 20 g. The score is shown in Table 2. Pain scale: Visual Analogue Scale (VAS) was used to assess patients' pain at 4, 8, and 12 weeks after repair [12]. Detection method: scale values of 0-10 cm scale plate were used to represent different degrees of pain.…”

Are Mechanical Vibrations an Effective Alternative to Accelerate Orthodontic Tooth Movement in Humans? A Systematic Review

“…According to eligibility criteria, it was decided to exclude six of them. Fifteen RCT studies were included in the synthesis review [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The process of identifying, selecting, and excluding studies are shown in a flow chart according to the PRISMA statement (Figure 1).…”

“…Ten studies used low-frequency vibrations [23,24,[26][27][28][32][33][34][35][36], and five studies analyzed the high-frequency vibrations [22,25,[29][30][31]. The devices used to generate the vibrations were as follows: AcceleDent (OrthoAccel Technologies, Inc., Bellaire, TX, USA) device [23,24,26,27,32,34,36], VPro5 (Propel Orthodontics, Ossining, NY, USA) [30], five studies applied the mechanical vibration with toothbrushes [25,28,29,31,33], one custom-made vibratory device [29], and one performed it with a dental massager whose brand was not specified [22].…”

“…The dental movement rate was measured by a digital caliper and by clinical inspections [23,28,32], measurements on plaster models [22,[24][25][26]29,31], digitized plaster models [27,33,35], or intraoral scanning [30,34,36].…”
