BUCK, Carmen Lucia Benetti Pardo et al. Evaluation of reimplanted teeth submitted to a new therapeutic protocol. Rev. Assoc. Paul. Cir. Dent. [online]. 2013, vol.67, n.1, pp. 22-26. ISSN 0004-5276.

The aim of this study was to evaluate clinically and radiographically the use of combination of calcium hydroxide, chlorhexidine gel 2% and zinc oxide (2:1:2) as a root canal filling paste without periodic replacements in reimplanted teeth. We examined single-rooted teeth (n=18), non vital, from 18 patients aged 7 to 25 years, irrespective of gender, treated at the Dental Trauma Service of the Endodontics Area, of the Piracicaba Dental School, State University of Campinas. The average time of root canal filling permanence was 2 years and during this period, clinical signs and radiographic findings were observed before and after insertion into the root canals. The data recorded was: occurrence of spontaneous pain, pain on vertical and horizontal percussion, pain on palpation, infraposition of replanted teeth, presence of lamina dura, inflammatory and/ or replacement root resorption, areas of periapical radiolucency and solubility of the root canal filling paste after a period of up to 4 years, without periodic exchanges. After therapy it was found that there was a significant statistically correlation between the absence of spontaneous pain, and percussion and palpation sensitivity (McNemar Test, p <0.05). The results also showed a significant reduction in cases of periradicular radiolucency and inflammatory resorption (Wilcoxon Test, p <0.05). It suggests that the root canal filling paste, used for long periods of time, without periodic replacements, can be an alternative for treatment of reimplanted teeth.
