As reabsorções radiculares múltiplas ou severas não estão relacionadas a fatores sistêmicos, suscetibilidade individual, tendência familiar e predisposição individual

Dental concussion: suggested protocol for controlling its consequences, treatment, prognosis and follow-up

“…Cases in which internal resorption dangerously approaches the root surface require thorough evaluation of how weak the root surface has become. 1,2 As in cases of internal resorption compromising both the cervical and middle thirds and approaching the root surface, therapeutic intervention might consist in osseointegrated implant replacement. Cases of more apically located internal resorption, even if near the root surface, might require apical endodontic surgery and apical third removal, before or after endodontic treatment, at clinical convenience.…”

“…In comparison, orthodontic movement produces less intense loads than that produced by occlusal trauma and concussion-like dental trauma. 1,2 Occlusal trauma and orthodontic movement forces do not have the characteristics that warrant the occurrence of rupture of fibers, vessels, nerves and tissue necrosis areas. In other words, since orthodontic and occlusal trauma forces are neither as intense nor suddenly applied, they do not lead to the same consequences of concussion-like dental trauma.…”

Root Resorption in Orthodontics: An Evidence-Based Approach

“…Immune cells migrate out of the capillaries in the periodontal ligament and interact with locally residing cells by elaborating a large array of signal molecules (Jäger et al, 2005). According Consolaro et al (2011), the causes of root resorption should be related to the loss of root surface cementoblasts.…”

“…Relevant details, such as mild trauma (concussion and subluxation) should be analyzed in detail (Consolaro et al, 2011).…”

“…The root resorption may compromise the continued existence and functional capacity of the affected tooth, depending on their magnitude (Brezniak & Wasserstein, 1993a, Brezniak & Wasserstein, 1993b, since the root structure (volume and contour) is changed (Consolaro, 2002). However, as the process of root resorption during orthodontic treatment is usually smooth and ends when the force is removed Levander et al, 1994) some authors have pointed out that the aesthetic and functional improvements justify the risks .…”
