Avaliação de dentes reimplantados submetidos a um novo protocolo terapêutico

O objetivo do presente estudo foi avaliar clinica e radiograficamente a utilizacao da associacao do hidroxido de calcio, clorexidina gel 2% e oxido de zinco (2:1:2), como pasta obturadora, sem substituicoes periodicas, em dentes reimplantados. Foram examinados dentes unirradiculares de (n=18) de 18 pacientes, de ambos os generos, na faixa etaria de 7 a 25 anos, atendidos no Servico te de Traumatismos Dentarios da Faculdade de Odontologia de Piracicaba FOP- Unicamp, icrea de Endodontia. O periodo medio de permanencia da pasta obturadora foi de 2 anos e foram observados sinais clinicos e radiograficos antes e apos sua insercao nos canais radiculares. Os dados registrados foram: presenca de dor espontânea, dor a percussao vertical e horizontal, dor a palpacao, infraposicao, presenca da lâmina dura, reabsorcoes radiculares inflamatorias e por substituicao, areas de radioluscencia periapical e a insolubilidade da pasta obturadora apos periodo de ate 4 anos, sem trocas periodicas. Verificou-se que houve uma diferenca estatisticamente significante em relacao a dor espontânea, a percussao e a palpacao (teste Mcnemarj p 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 canais. 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
