“…The levels of OIIRR in each group were similar and correspond to previous reports for orthodontic treatment using fixed appliances. [4][5][6][7]10,44 Additionally, OIIRR measured at the maxillary central incisor was not significantly influenced by age or sex of the patient, initial root length, history of dentoalveolar trauma during treatment, relative duration of the alignment phase or pain experience during this phase. Finally, the proportion of patients with severe OIIRR (>2 mm) was in agreement with previous studies 4,9,45 , similar amongst experimental groups and therefore not influenced by the use of vibrational force.…”

“…OIIRR most commonly affects the maxillary incisor, mandibular incisor and first permanent molar teeth 4,5 and is usually mild in nature, with only around 16% of orthodontic patients having clinically-relevant shortening of at least one tooth. [6][7][8][9] The aetiology of OIIRR is believed to be multifactorial with many factors influencing outcome, including root morphology, 10 history of dentoalveolar trauma, 4 patient age 6 and the presence of any underlying systemic inflammatory condition, such as asthma or allergy. [11][12][13] Factors related to orthodontic treatment include the level and direction of force, [14][15][16][17][18] type of force 19,20 and contact of tooth roots with cortical bone.…”

INTRODUCTION A multicenter parallel 3-arm randomized clinical trial was carried out in 1 university and 2 district hospitals in the United Kingdom to investigate the effect of supplemental vibrational force on orthodontically induced inflammatory root resorption (OIIRR) during the alignment phase of fixed appliance therapy. METHODS Eighty-one subjects less than 20 years old with mandibular incisor irregularity undergoing extraction-based fixed-appliance treatment were randomly allocated to supplementary (20 minutes a day) use of an intraoral vibrational device (AcceleDent; OrthoAccel Technologies, Houston, Tex) (n = 29), an identical nonfunctional (sham) device (n = 25), or fixed appliances only (n = 27). OIIRR was measured blindly from long-cone periapical radiographs of the maxillary right central incisor taken at the start of treatment and the end of alignment when a 0.019 × 0.025-in stainless steel archwire was placed (mean follow-up, 201.6 days; 95% confidence interval [CI], 188.6-214.6 days). Data were analyzed blindly on a per-protocol basis because losses to follow-up were minimal, with descriptive statistics, 1-way analysis of variance, and univariable and multivariable regression modeling. RESULTS Nine patients were excluded from the analysis; they were evenly distributed across the groups. Mean overall OIIRR measured among the 72 patients was 1.08 mm (95% CI, 0.89-1.27 mm). Multivariable regression indicated no significant difference in OIIRR for the AcceleDent (difference, 0.22 mm; 95% CI, -0.14-0.72; P = 0.184) and AcceleDent sham groups (difference, 0.29 mm; 95% CI, -0.15-0.99; P = 0.147) compared with the fixed-appliance-only group, after accounting for patient sex, age, malocclusion, extraction pattern, alignment time, maximum pain experienced, history of dentoalveolar trauma, and initial root length of the maxillary right central incisor. No other side-effects were recorded apart from pain and OIIRR. CONCLUSIONS The use of supplemental vibrational force during the alignment phase of fixed appliance orthodontic treatment does not affect OIIRR associated with the maxillary central incisor. REGISTRATION ClinicalTrials.gov (NCT02314975). PROTOCOL The protocol was not published before trial commencement. FUNDING Functional and sham AcceleDent units were donated by the manufacturer; there was no contribution to the conduct or the writing of this study.

“…Early investigators of this phenomenon such as Ketcham(1) and Phillips(2) found maxillary incisors to be the most susceptible. At this time, evidence indicates that a routine course of orthodontic treatment will lead to an average apical resorption of 1 to 2 millimeters(mm) for upper incisors (3,4,5,6,7,8) with 2 3% of patients showing a loss of 4 mm or more (4,7,9).…”

“…The teeth more susceptible to ARR are the maxillary and mandibular incisors, and especially the maxillary lateral incisors (Linge & Linge, 1983;Mirabella & Artun, 1995). The introduction of self-ligating brackets provoked the investigation of archwire ligation on ARR.…”
