Resumo: The aim of this study was to evaluate the antiseptic efficacy of rotary instrumentation associated with calcium hydroxide-based pastes prepared with different vehicles and antiseptics. Chronic periapical lesions were experimentally induced in 72 premolar root canals of four dogs. Under controlled asepsis, after initial microbiological sampling (A1), the root canals were instrumented using the ProFile system in conjunction with 5.25% sodium hypochlorite and the intracanal medication was placed. Four experimental groups were formed according to the pastes used: group 1- Calen (n=18), group 2- Calen+CPMC (n=20), group 3- Ca(OH)2 p.a.+ anaesthetic solution (n=16) and group 4- Ca(OH)2 p.a.+ 2% chlorhexidine digluconate (n=18). After 21 days, the pastes were removed; the canals were emptied and 96 hours later a second microbiological sample was obtained (A2). The incidence of positive microbiological cultures and the number of cfus in stages A1 and A2 were compared statistically by the Wilcoxon test while the influence of the different treatments in intracanal infection was evaluated by Kruskal-Wallis test at 5% significance level (p

Lesões periapicais crônicas foram experimentalmente induzidas em 72 canais radiculares de pré-molares de 4 cães. Sob controlada assepsia, após amostras microbiológicas iniciais (A1), fez-se a instrumentação com o sistema ProFile coadjuvado pela solução de hipoclorito de sódio a 5,25%, seguido de medicação intracanal. Em função das pastas utilizadas obtiveram-se 4 grupos: grupo 1- Calen (n=18), grupo 2- Calen+PMCC (n=20), grupo 3- Ca(OH)2 p.a.+ solução anestésica (n=16) e grupo 4- Ca(OH)2 p.a.+ solução de digluconato de clorexidina a 2% (n=18). Transcorridos 21 dias, removeram-se as pastas, deixando os canais radiculares vazios e 96 horas após obteve-se a segunda amostragem microbiológica (A2). O número de unidades formadoras de colônias de microrganismos (ufc) e a incidência de culturas positivas antes e após cada tratamento foram analisados pelo teste de Wilcoxon enquanto a influência dos diferentes tratamentos na infecção intracanal foi avaliada pelo teste de Kruskal-Wallis com nível de signficância de 5,0%. Verificaram-se nas amostras A1 elevadas quantidades de anaeróbios obrigatórios, facultativos e estreptococos do grupo viridans em 100% dos canais radiculares. Nas amostras A2, todos os tratamentos proporcionaram significativa redução do número de ufc e de culturas positivas (pUniversidade de São Paulo.
