Abstract(s)
A reabsorção radicular dentária é caracterizada por perda da estrutura mineralizada da raiz do dente. Esse processo pode ser definido como fisiológico quando ocorre em decíduos que se encontram em processo de esfoliação ou patológico, quando se apresenta em dentes permanentes.
A Ortodontia é provavelmente a única especialidade odontológica que realmente usa o processo inflamatório como um meio de resolver os problemas funcionais e estéticos. Eles devem conhecer os fatores de risco de reabsorção radicular e fazer tudo para reduzir a ocorrência de reabsorção radicular. O tratamento ortodôntico é um tratamento com riscos próprios, inevitáveis apesar de considerados clinicamente aceitáveis, quando controlados. A reabsorção radicular é uma das mais comuns e indesejáveis sequências deste tratamento, resultante da perda permanente da estrutura dentária a partir do ápice da raiz, podendo comprometer o sucesso do tratamento ortodôntico. A reabsorção radicular apical externa é um problema comum e, às vezes, crítico, relacionado com o tratamento ortodôntico. Esta ocorre devido às forças mecânicas compressivas aplicadas no periodonto e leva à perda de tecido dentário radicular (cemento e dentina), tendo pouca previsibilidade a tendência individual ou a extensão das possíveis lesões. A ocorrência de reabsorção radicular apical externa tem sido relatada com e sem tratamento ortodôntico e pode ser diagnosticada por ortodontistas durante a rotina de diagnóstico, de progresso e pós-tratamento através de radiografias. A reabsorção radicular apical externa (EARR) é um fenótipo multifatorial complexo, determinado pelo hospedeiro e por factores ambientais, que ainda não estão claramente identificados. É fundamental um bom diagnóstico e uma prevenção através de controlo radiológico.
The dental root resorption is characterized by loss of the tooth root of the mineralized structure. This process can be defined as physiologic when it occurs in deciduous which are exfoliation process or pathological, when present in permanent teeth. Orthodontics is probably the only dental specialty that actually uses the inflammatory process as a means of solving the functional and aesthetic problems. They should know the root resorption risk factors and do everything to reduce the occurrence of root resorption. Orthodontic treatment is a treatment with own risks unavoidable despite clinically acceptable where controlled. The root resorption is one of the most common and undesirable sequences of this treatment, resulting in permanent loss of tooth structure from the root apex, which can compromise the success of orthodontic treatment. External apical root resorption is a common problem and sometimes critical, related to orthodontic treatment. This occurs due to compressive mechanical forces applied in the periodontium leads to loss and root dental tissue (cementum and dentin), having little predictability individual trend or the extent of possible injury. The occurrence of external apical root resorption has been reported with and without orthodontic treatment can be diagnosed by orthodontists during routine diagnosis, progress and post-treatment by X-rays. The external apical root resorption (EARR) is a complex multifactorial phenotype determined by the host and environmental factors which are not clearly identified. A good diagnosis and prevention through radiological control is crucial.
