Resumo: Objetivos: O objetivo deste estudo foi avaliar, ex vivo, a porcentagem da obtenção de patência apical nos canais radiculares dos primeiros molares superiores permanentes e a influência da ampliação cervical nesta verificação. Método: Foram analisados 73 primeiros molares superiores permanentes, selecionados através de exame visual e radiográfico. Para a execução do estudo, os dentes foram previamente abordados e os canais radiculares localizados. A patência apical foi verificada utilizando-se instrumentos de aço inoxidável #08 ou #10, de acordo com o diâmetro de cada canal radicular. Quando não se conseguia a patência apical, o terço cervical foi ampliado, com brocas de Gates-Glidden #1 e #2, seguidas de brocas LA Axxess #20 e a tentativa de obtenção de patência, executada novamente. Resultados: Os resultados obtidos, com relação à presença de patência apical, foram de 79,45% para os canais radiculares mesiovestibulares, 29,62% para os canais radiculares mesiopalatinos, 72,60% para os canais radiculares distovestibulares e 84,93% para os canais radiculares palatinos. Conclusão: Pode-se concluir que a ampliação do terço cervical aumentou em 8,42% a obtenção de patência apical em todos os canais radiculares.

Abstract: Aim: The aim of this study was to evaluate, ex vivo, the percentage of patency in the root canals system of the first maxillary permanent molars and the influence of the cervical prepare in this maneuver. Methods: Seventy-three first maxillary permanent molars were analyzed and selected by visual and radiograph examination. To execute the study, the teeth were previously accessed and the canals were located. The patency was verified by using stainless steel instruments #08 or #10, according to the diameter of each root canal. When the patency could not be achieved, the cervical third was enlarged with Gates-Glidden drills #1 and #2, followed by LA Axxess drills #20 and attempts to reach patency again. Results: The results for the presence of patency, were 79.45% for mesiobuccal root canals, 29.62% for second J Oral Invest 1(2): 17-21, 2012 mesiobuccal root canals, 72.60% for distobuccal root canals and 84.93% for palatine root canals. Conclusion: It can be concluded that the cervical prepare increases in 8.42% the presence of patency in all root canals.
