Sampaio Nikeila C. de Oliveira Conde The role of dentin cleaning is to remove debris that may impair adaptation and marginal sealing, quantitatively reducing microorganisms. The aim of this study was to investigate through scanning electron microscopy (SEM) the morphology of the dentin surface, cut and treated with copaiba oil emulsions (CO) and suspension of ethanol extract of propolis (EP). Twenty four upper pre-molars teeth, divided into eight groups (n=3), were used: G1: no cleaning, G2: air/water spray, G3: 10% CO, G4: 10% CO + A, G5: 30% CO, G6: 30% CO + A, G7: 1% EP, G8: 2% Chlorhexidine. The specimens were dentin discs (1 mm Ø). The SEM photomicrographs were classified and the results were: G1 - Debris dentin on the entire image / countless microorganisms, G2 and G7 - 50-100 debris / countless microorganisms and G3, G4, G5, G6 and G8 - 0-50 debris / countable microorganisms (50-100 colonies). Conclusion: The present results suggest that copaiba oil emulsions (CO) and suspension of ethanol extract of propolis (EP) have feasibility to be used as bioactive dental cleaning agents. 05 11 2016 182 187 TODENTJ-10-182 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2015-12-30 2016-1-10 2016-1-28 2016-05-11 https://creativecommons.org/licenses/by/4.0/legalcode 10.2174/1874210601610010182 1553506456 https://opendentistryjournal.com/VOLUME/10/PAGE/182/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-182/TODENTJ-10-182.xml Int J Laser Dent Ajilal S.K. 2 1 2012 10.5005/jp-journals-10022-1009 Ajilal SK, Sam RJ, Babu R, Suganthan P.
