[Follow-up investigation of the effect of Ca(OH)2 on the teeth with necrotic pulps and immature root development and surrounding periodontal tissues].

Abstract

In this study Ca(OH)2 + distilled water was applied to the traumatized necrotic incisor teeth with immature root development. After necessary mechanical and chemical root canal disinfection the paste was applied to 13 teeth of 9 patients. Periodontologic problems in vestibule gingiva of the teeth prior to the treatment doubted if the primary lesion was the necrotic pulp or periodontal infection. After control periods (6 weeks, 3 months, 6,9,12,18,24 months) the cases were evaluated roentgenographically whether the apical closure was obtained. After observation of calcified tissue in the apex the canals were filled with sectioned warm gutta percha with vertical condensation. All the cases were successful except one and after treatment restorations were performed. In case all the patients experienced periodontologic problems from the teeth prior to treatment, after endodontic treatments and application of Ca(OH)2 to the canal, healing of periodontal tissues were also observed. This finding shows the importance of differential diagnose of periodontal problems caused by pulpal necrosis.
