Abstract Orthodontically induced external apical root resorption (OIEARR) is a major concern regarding periodontal status after nonsurgical orthodontic treatment. The aim of this study was to assess this sequel by a systematic review of published data. For assessment, we performed an electronic search of one database for comprehensive data, using keywords in different combinations: “root resorption”, “periodontics” and “nonsurgical orthodontic treatment”. We supplemented the results searching by hand in published journals and we cross-referenced with the accessed articles. Patients included in the results presented a good general health status, with no previous history of OIEARR and no other associated pathologies. Finally, twenty-three studies were selected and included in this review. A high prevalence (69–98%) and moderate severity of OIEARR (<5 mm and <1/3 from original root length) were reported. No difference in root resorption was found regarding the sex of the patients. A moderate positive correlation between treatment duration and root resorption was found. Also, a mild correlation regarding antero-posterior apical displacement and root resorption was found.

OBJECTIVE: To determine the normative orthodontic treatment need among 12-year-old Brazilian schoolchildren, in the municipality of Juiz de Fora, Minas Gerais, Brazil, and compare with the need as perceived by the children themselves and their parents or caregivers, assessing putative associated sociodemographic factors. METHODS: Four hundred and fifty one children without a previous history of orthodontic treatment were randomly selected from a population of 7,993 schoolchildren regularly attending the public and private educational sectors of the municipality of Juiz de Fora, Minas Gerais, Brazil. RESULTS: The prevalence of normative orthodontic treatment need in 12-year-old children, assessed with the Dental Aesthetic Index (DAI) was 65.6% (n = 155). The need perceived by the caregivers was 85.6%, and by the children was 83.8%. Only the perception by the caregivers maintained a significant correlation with the normative need of treatment when adjusted to the parents' schooling and economical level (p = 0.023). CONCLUSIONS: There is a high prevalence (65.6%) of malocclusion requiring orthodontic treatment in 12-year-old Brazilian schoolchildren. The most prevalent malocclusions in the study were: Crowding, Class II molar relationship and increased overjet. There was no significant correlation between the Index of Orthodontic Treatment Need - Aesthetic Component (IOTN-AC) related to dental aesthetic perception and the normative treatment need assessed with the DAI.

The aim of this paper is to provide a review on the role of inflammation in orthodontically induced inflammatory root resorption (OIIRR) and accelerating orthodontic tooth movement (AOTM) in orthodontic treatment. Orthodontic tooth movement (OTM) is stimulated by remodeling of the periodontal ligament (PDL) and alveolar bone. These remodeling activities and tooth displacement are involved in the occurrence of an inflammatory process in the periodontium, in response to orthodontic forces. Inflammatory mediators such as prostaglandins (PGs), interleukins (Ils; IL-1, -6, -17), the tumor necrosis factor (TNF)-α superfamily, and receptor activator of nuclear factor (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) are increased in the PDL during OTM. OIIRR is one of the accidental symptoms, and inflammatory mediators have been detected in resorbed roots, PDL, and alveolar bone exposed to heavy orthodontic force. Therefore, these inflammatory mediators are involved with the occurrence of OIIRR during orthodontic tooth movement. On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

21168 Background: Bevacizumab is an increasingly used anti-cancer treatment with common side effects including hypertension (htn) and proteinuria which occur in approximately 10% and 20% of the patients, respectively. Little is known regarding ethnic variations of bevacizumab induced htn and proteinuria, particularly in African-Americans (AA) who have a high prevalence of htn and susceptibility to kidney disease. Methods: We conducted a retrospective chart review of patients who completed bevacizumab alone or as a chemotherapy regimen at the University of Illinois at Chicago for an 18-month study period. We collected blood pressure (BP) measurements and urinanalyses before starting bevacizumab, during bevacizumab and after stopping bevacizumab, in addition to concurrent medications, past medical history and demographics. Htn and proteinuria were graded by CTC v3.0. Patients with less than two successive doses of bevacizumab or unreliable ethnicity were excluded. Results: 27 subjects were eligible. Eighteen AA (67%) and 9 (33%) non-AA were included. Twenty-two (81%) had colorectal cancer. AA received a median of 10 cycles and non-AA received a median of 6 cycles. Six subjects (22%) developed any grade htn toxicity; maximum grade: grade 2=4 (15%), grade 3=2 (7%). Htn toxicity occurred in 28% AA and 11% non-AA (p=NS). Previous history of hypertension was found in 15 subjects (55%): AA=14 vs. non-AA=1 (p=0.002) and was not correlated with hypertensive toxicity. Twelve subjects (44%) developed any grade proteinuria; maximum grade: grade 1=9 (33%), grade 2=3 (11%). Proteinuria toxicity occurred in 50% AA and 33% non-AA (p=NS). Presence of hypertensive toxicity was associated with increased risk of proteinuria. Clinical benefit (PR, SD) was seen in 15 subjects (55%). Rate of clinical benefit was 67% in AA and 33% in non-AA (p=NS). Clinical benefit did not correlate with hypertensive or proteinuria toxicities. Conclusions: AA were more prone than non-AA to bevacizumab induced hypertension and proteinuria toxicity in this retrospective study. Higher clinical benefit was seen in AA.
