3 Proper debridement, disinfection and obturation of root canal is difficult in such cases thus compromising root canal treatment. 1 2 The American Association of Endodontists included teeth with radiographic indiscernible root canals requiring treatment in high difficulty criteria. It does not store any personal data.Traumatised teeth usually develop pulp canal obliterations and are characterised by radiographic loss of pulp space and yellowish discoloration of clinical crown.

A protocol of localization, exploration, cleaning and shaping, plus use of intracanal medication and root canal filling, prevented iatrogenic complications and allowed the case to be successful.ĭental pulp calcification, Orthodontics, corrective, Tooth injuries, Conclusions: The PCO caused by the association of dental trauma with longterm orthodontic treatment may have evolved into pulp necrosis and consequently to apical periodontitis. Results: After 12 months, the patient showed no signs or symptoms and the periradicular lesions of the lower central incisors were completely healed. Instrumentation of the root canals were carried out by using the pre-enlargement technique, with a calcium hydroxide, paramonochlorophenol and glycerine- based paste being used as intracanal medication for 15 days, followed by thermoplastified obturation and restoration with photopolymerisable resin. One-quarter clockwise and counter-clockwise insertion, retraction and rotation movements, all common to precurved #10 K-files, were performed until reaching the apical patency. The endodontic treatment was conducted and the root canals were located by using an optical microscope at 25x magnification. Two years after the conclusion of an orthodontic treatment, radiolucent lesions involving the lower central incisors were observed and endodontic treatment was unsuccessfully initiated by a general practitioner, who could not locate the root canals due to PCO. Methods: A female 22-year-old patient sought dental care at the endodontic centre reporting to have suffered a dental trauma in the antero-inferior region, followed by a 5-year orthodontic treatment. Introduction: To describe the endodontic treatment of lower incisors with pulp canal obliteration (PCO) and apical periodontitis after dental trauma and long-term orthodontic treatment.
