ABSTRACT Objectives:  To evaluate the effects of low-intensity pulsed ultrasound (LIPUS) on orthodontically induced tooth root resorption caused by torque in human subjects. Materials and Methods:  Ten healthy patients (12–35 years of age) who required extraction of all first premolars as a part of their routine orthodontic treatment were recruited. A 15° twist was applied in the arch wire using 0.019 × 0.025-inch TMA in a 0.022-inch bracket system (Synergy R) that produced a buccal root torque of approximately 5 N/mm at the bracket level. Using a split mouth design, randomization, and blinding, one side of the arch received LIPUS for 20 minutes per day for 4 weeks at an incident intensity of 30 mW/cm2 of the transducers’ surface area. The other side served as a self-control, which received a sham transducer. After 4 weeks, all first premolars were extracted and micro–computed tomographic analysis was performed on these extracted teeth. A linear mixed-model statistical analysis was used. Results:  LIPUS-treated teeth showed significantly less total volume of resorption lacunae compared to control teeth by a mean difference of (0.54 ± 0.09 mm3) (P < .001) and percentage of root resorption by a mean difference of (0.33 ± 0.05 mm3) (P < .001). In addition, significantly fewer resorption lacunae were found on all root surfaces in the LIPUS group compared to the control except in the instance of the distal surface. Limitations:  This study was performed on limited number of cases during a 4-week period. Conclusions:  LIPUS minimizes root resorption when applied during torque tooth movement over a 4-week period.

The aim of this study was to evaluate the possible effect of low intensity pulsed ultrasound (LIPUS) on tooth movement and root resorption in orthodontic patients. Twenty-one patients were included in a split-mouth study design (group 1). Ten additional patients were included with no LIPUS device being used and this group was used as the negative control group (group 2). Group 1 patients were given LIPUS devices that were randomly assigned to right or left side on upper or lower arches. LIPUS was applied to the assigned side that was obtained by randomization, using transducers that produce ultrasound with a pulse frequency of 1.5 MHz, a pulse repetition rate of 1 kHz, and average output intensity of 30 mW/cm2. Cone-beam computed tomography (CBCT) images were taken before and after treatment. The extraction space dimensions were measured every four weeks and root lengths of canines were measured before and after treatment. The data were analyzed using paired t-test. The study outcome showed that the mean rate of tooth movement in LIPUS side was 0.266 ± 0.092 mm/week and on the control side was 0.232 ± 0.085 mm/week and the difference was statistically significant. LIPUS increased the rate of tooth movement by an average of 29%. For orthodontic root resorption, the LIPUS side (0.0092 ± 0.022 mm/week) showed a statistically significant decrease as compared to control side (0.0223 ± 0.022 mm/week). The LIPUS application accelerated tooth movement and minimized orthodontically induced tooth root resorption at the same time.

Acceptable speed of tooth movement in orthodontics is main limiting factor in treatment time. Although there are many devices and accessories which helps to move teeth – big forces in small period can cause complications like tooth resorption. The paper aimed to verify low-intensity pulsed ultrasound as method to accelerate orthodontic movement. A literature review from 2002-2020 using data bases like PubMed and Medline was performed. LIPUS orthodontics, LIPUS in dentistry, low-intensity pulsed ultrasound. 35 articles associated with the aim of this review were chosen and analyzed. Low-intensity pulsed ultrasounds start biological sequence on molecular level. Reactions on cellular structures accelerate bone healing and reduce negative effects and complications during treatment. Low-intensity pulsed ultrasounds have positive impact on bone wounds healing, treating developmental bone defects, cartilage and soft tissues reactions, tooth resorption, teeth tissue and periodontal regeneration and on orthodontic treatment acceleration.
