A 20 year old female patient attended the dental hospital of the Regional Military Hospital, Guadalajara, Jalisco. The patient's complaint was tooth discoloration. Exploration revealed dyschromia in the upper central right incisor. Sensitivity tests elicited negative results, radiographic examination revealed lack of radio-lucid areas. Emitted diagnosis was pulp necrosis. Root canal treatment was conducted in one single visit. Intra-coronary whitening with thermo-catalytic technique was achieved at a later date. Clinical and radiographic follow-up were conducted 3, 6 and 12 months after procedure. At these sessions the following traits were observed: suitable clinical evolution, absence of symptomatology, radio-lucid area and suitable coloring of dental tissues.
