“…Our findings are thus less severe than those found by Smale et al 32 who reported that 8.5% of their patients had one or more maxillary incisors with index score 3 after 3 to 9 months of treatment. The corresponding number of maxillary incisors in our study was 3.1% ( Table 2).…”

“…The corresponding number of maxillary incisors in our study was 3.1% ( Table 2). The difference is even larger for the less severe resorption where Smale et al 32 found score 2 in one or more incisors in 40% of the patients, whereas score 2 was registered on maxillary incisors in 9.3% of the patients in the present study (Table 2). Levander and Malmgren 37 also investigated OIRR during initial orthodontic treatment.…”

Objectives: To investigate root resorption after 6 months of active orthodontic treatment and its relation to possible risk factors. Materials and Methods: Ninety-seven patients (10-18 years) with a Class I malocclusion and crowding treated with fixed appliance and premolar extractions were examined with cone beam computed tomography before and after 6 months of active treatment. The exposure covered all teeth from first molar to first molar in both jaws. The Malmgren index was used to evaluate the degree of root resorption. Irregular root contour (score 1) was seen in most teeth already before active treatment, and therefore resorptions were registered only as score 2 (,2 mm, minor resorption) or higher. Results: Minor root resorption was noted in 10% of the patients and severe root resorption, .2 mm (score 3) was found in four patients. Root resorption was more frequently seen in the upper jaw, especially the incisors. There was no statistically significant correlation of root resorption with any of the selected risk factors. Conclusions: After 6 months of treatment, clinically significant resorption was diagnosed in 4% of the patients, ie, in 96% of the patients the radiographic examination did not reveal any significant information. The selected risk factors did not have any impact on the amount of resorption after 6 months of active treatment. (Angle Orthod. 2012;82:196-201.)

“…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.

“…However, if pre-treatment radiographs show evidence of pre-existing root resorption or if, as described earlier, the root morphology indicates a risk of developing root resorption, then these patients should have progress radiographs taken at six to nine months. 12,16 With adult patients, the loss of alveolar bone and possible root resorption are risk factors that need special consideration and warrant the taking of progress radiographs Irrespective of age, for patients 3.…”
