“…A study by Sergl and Zentner [4] on the psychological side of the orthodontic patients found that about two-thirds were concerned about poor aesthetic. Nevertheless, the overall duration of orthodontic treatment not only worries the patients and parents, but also the orthodontists [5].…”

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/cm 2 . 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.

“…An increasing number of adults are undergoing orthodontic treatment and the most common concern for these patients is the treatment duration, in addition to the type of orthodontic appliance to be used in the treatment [5]. The average orthodontic treatment is from 2-3 years [6,7].…”

Factores que afectan la duración de los tratamientos de ortodoncia en un Servicio Público de Salud. Int. J. Odontostomat., 13(3):321-324, 2019. RESUMEN: La duración de los tratamientos de ortodoncia siempre ha sido una de las mayores preocupaciones, tanto en los pacientes como en los Ortodoncistas. El proposito de esta investigacion fue determinar la magnitud de las inasistencias a los controles por parte de los pacientes y como estas y otras variables, influyen en la duración de los tratamientos de Ortodoncia en el Centro de Salud Familiar (CESFAM) Dr. Victor Manuel Fernandez, Servicio de Salud de Concepcion, Chile. Se realizo un estudio descriptivo, de tipo transversal, retrospectivo, en el que se utilizaron las fichas clínicas de todos los pacientes que fueron dados de alta por los Ortodoncistas del CESFAM Dr. V. M. F. durante el año 2017. La tabulación se realizó en Microsoft Excel y el análisis estadístico se hizo en InfoStat 17. Se incluyeron 246 pacientes, con una edad de ingreso promedio de 13,6 años. La maloclusion predominante fue la Clase I de Angle (71 %). Estos pacientes tuvieron una duracion de tratamiento promedio de 33,9 meses. Se concluyó que a mayor cantidad de inasistencias, el tratamiento de ortodoncia tuvo una duración mayor.PALABRAS CLAVE: ortodoncia, duración de tratamiento, efectividad del tratamiento.

“…The impact of time on the treatment efficiency has been previously published. 24 A sample of 70 patients with Class I and Class II malocclusion treated by the same orthodontist during the same time period as the cases included in this study was considered. The aim was to determine whether or not there was a correlation between the year when treatment was started and the duration of orthodontic treatment.…”

Objective: The purpose of this study was to assess the efficiency of compensatory orthodontic treatment of patients with mild Class III malocclusion with two preadjusted bracket systems. Method: Fifty-six matched patients consecutively treated for mild Class III malocclusion through compensatory dentoalveolar movements were retrospectively evaluated after analysis of orthodontic records. The sample was divided into two groups according to the brackets used: Group 1 = non-Class III compensated preadjusted brackets, Roth prescription (n = 28); Group 2 = compensated Class III preadjusted brackets, Capelozza III prescription (n = 28). Cephalometric analysis, number of appointments and missed appointments, months using Class III elastics, and bond/band failures were considered. Treatment time, Peer Assessment Rating (PAR) index at the beginning (PAR T1) and end of treatment (PAR T2) were used to calculate treatment efficiency. Comparison was performed using a MANOVA at p< 0.05. Results: Missed appointments, bond or band failures, number of months using the Class III intermaxillary elastics, and cephalometric measurements showed no statistically significant difference (p> 0.05) between groups. Patients treated with Roth brackets had a treatment time 7 months longer (p= 0.01). Significant improvement in the patient’s occlusion (PAR T2-T1) was observed for both groups without difference (p= 0.22). Conclusions: Orthodontic brackets designed for compensation of mild Class III malocclusions appear to be more efficient than non-compensated straight-wire prescription brackets. Treatment time for Class III patients treated with brackets designed for compensation was shorter than with Roth prescription and no difference in the quality of the occlusal outcome was observed. A prospective randomized study is suggested to provide a deeper look into this subject.
