Sažetak
INTRODUCTON: Internal root resorption in permanent teeth is a complex interaction of inflammatory and resorbing cells, resulting in the formation of multinucleated giant cells and resorption of dental hard tissues. Traumatic injury, infection and orthodontic treatment have been suggested as etiological factors for internal resorption. INITIAL STATE: A 38-year-old male patient attended the Dental clinic at University of Rijeka, Faculty of Medicine, Rijeka, Croatia, complaining the inflammation in the buccal region of the mandibullary right central incisor with a sinus tract presented without any pain. The tooth had been traumatized in a football accident during adolescence. Upon clinical examination a sinus tract was observed in the medial third of the root. Radiographic examination revealed the presence of a radiolucent image in the middle third of the root internally, in addition to a well defined periapical bone resorption on the mandibullary right central incisor (Fig.1). On the left incisor, only the periapical leason was presented. DIAGNOSIS: These findings suggest internal root resorption and chronical periapical periodontitis. TREATMENT PROCESS: During the first session, after placement of a rubber dam, the root canal treatment was performed with step-back instrumentation technique (Fig.2). The canal was irrigated with 2.5% sodium hypochlorite followed by final irrigation with 17% EDTA solution for 3 min. Next, a calcium hydroxide paste with saline was applied 2 times in a 30 days period by the end of which the sinus tract had disappeared. Before root canal obturation, the calcium hydroxide paste was removed from the root canal using the working length file and the canal was irrigated with 2.5% sodium hypochlorite solution, followed by final irrigation with 2 ml of EDTA for 3 min and drying with absorbent paper points. The root canal obturation was performed one month after initial therapy using the Obtura II system (Obtura Spartan, Fenton, USA) as a back-filling technique (Fig.3). The cavity was sealed with composite restorative material. RESULTS: In the follow-up after 2.5 years, clinically examination revealed that the patient had no symptoms, without sinus tract and with a normal configuration of the adjacent soft tissue. The radiographic examination showed periodontal bone repair with no signs of internal root resorption enlargement (Fig.4). RECOMMENDATIONS: This case indicates that the correct diagnosis and treatment planning are critical for clinical management and success. In the presence of internal root resorption the use of injected thermo plasticized gutta-percha techniques are recommended.
