VAZ, Irene Pina et al. Treatment of upper central incisors after trauma. RGO, Rev. gaúch. odontol. (Online) [online]. 2011, vol.59, n.2, pp. 305-311. ISSN 1981-8637.

Presently, dental trauma is one of the main causes for seeking a dental surgeon. The present paper presents a case report of dental trauma, addressing the different pulp reactions of the affected teeth and a treatment plan. The authors identified two distinct types of pulp reactions in teeth (tooth 21 and 11) subject to the same trauma. After clinical and radiographic examination, the differential diagnosis between periapical lesion on tooth 21 and radiolucency of the nasopalatine foramen was performed. Pulpal necrosis, without periapical lesion, was diagnosed in tooth 21, and live pulp in tooth 11, with internal and external root resorption. A treatment plan was designed, which included root canal treatment of teeth 21 and 11, as well as aesthetical restoration of both using internal and external bleaching techniques. This treatment resulted in optimal aesthetic outcome with relatively low cost. The 2-year follow-up confirmed the success and longevity of the treatment
