MARTINEZ LOZANO, MA; FORNER NAVARRO, L  e  SANCHEZ CORTES, JL. Clinical considerations on external root resorptions caused by dental impactation. Av Odontoestomatol [online]. 2003, vol.19, n.1, pp.29-33. ISSN 2340-3152.

Pressure external root resorption (PERR) is a loss of dental root tissues (dentine and cementum) that begin in the periodontal area caused by a impacted teeth. We show three cases with differents clinical situations and therapeutical aspects. Pulpal injurie and difficulty in the post-endodontic cavity acces are characteristiques of these processes. Depending on the level of tissue destruction we discusse the therapeutical orientation in each case. Some treatments like class V type 5 cavities or fillings with cermet glass-ionomer in the more atipical situations (generally after an endodontic treatment) are a good choice in these situations.
