Risk variables of external apical root resorption during orthodontic treatment

Abstract

INTRODUCTION: External apical root resorption (EARR) is an adverse outcome of the orthodontic treatment. So far, no single or associated factor has been identified as responsible for EARR due to tooth movement. OBJECTIVE: This study investigated the association of risk variables (age, gender, extraction for orthodontic treatment and Angle classification) with EARR and orthodontic treatment. METHOD: The sample (n=72) was divided into two groups according to presence (n=32) or absence (n=40) of EARR in maxillary central and lateral incisors after orthodontic treatment. RESULTS: There were no statistically significant differences in EARR according to age, gender, extraction or type of malocclusion (p>0.05). CONCLUSION: The risk variables examined were not associated with EARR in the study population

Evaluation of apical root resorption occurrence in orthodontic patients treated with fixed braces depending on selected clinical parameters

“…In the study group the youngest patient was 9, and the oldest one -37, while in the control group respectively 11 and 43. Some researchers also did not prove any influence of age on root resorption [35][36][37]. Only Sameshima and Sinclair observed that resorption is more common in adults than in children [38].…”

“…Various studies prove that there is no relationship between root resorption and type of malocclusion [35,37,39,40]. In the study conducted by Harris et al, skeletal class was evaluated on the basis of ANB angle and Wits appraisal (AOBO).…”

Terdapat banyak penelitian yang menghubungkan berbagai variabel ini dengan kondisi resorpsi akar apikal eksternal, tapi ditemukan hanya ada sedikit kesepakatan di antara peneliti mengenai pengaruh faktor ini.…”

Reabsorção radicular em tratamento ortodôntico

“…Segundo a Associação Americana de Ortodontia, a Ortodontia é o ramo da Medicina Dentária que se ocupa da supervisão, orientação e correção do crescimento e maturação das estruturas dentofaciais, incluindo as condições que necessitam de movimentos dentários, ou da correção das relações deficientes, ISSN 1983-5183 ou das deformações de estruturas associadas por meio do ajuste das relações entre os dentes e os ossos faciais pela aplicação de forças e/ou estímulo e redirecionamento das forças funcionais dentro do complexo craniofacial 6 . O tratamento ortodôntico, contudo, é um tratamento com riscos intrínsecos, inevitáveis, apesar de considerados clinicamente aceitáveis, quando controlados 7 .…”

“…A reabsorção radicular é uma das mais comuns e indesejáveis sequelas do tratamento ortodôntico, resultante da perda permanente da estrutura dentária a partir do ápice da raiz, podendo comprometer o benefício e o sucesso do tratamento ortodôntico 7 .…”
