There is no register of PDT studies evaluating protocols to minimize that concern. The present study evaluated the efficiency of chemical adjuncts in methylene blue dye (MB) removal after PDT. Materials and methods: Forty single-rooted teeth, after root canal preparation, were filled with 0.01% MB for 5 min, and irradiated with diode laser 660 nm at 40 mW for 240 sec (total energy 9.6 J). The specimens were divided into four groups (n = 10), according to the chemical adjuncts used for dye removal: (a) 2.5% sodium hypochlorite (NaOCl); (b) 2.5% NaOCl + Endo-PTC cream; (c) 70% ethyl alcohol and (d) saline (control). The crowns were sectioned and fixed in a device. Photographs were taken before the PDT (T0), immediately after (T1) and upon dye removal (T2). The chromatic alterations were evaluated using Adobe Photoshop and K values were determined in four fixed points of each crown. Results: K values (dental staining) increased in all groups when comparing T0 and T1. The effectiveness of the tested adjuncts was, in decreasing order: G1 (−3.11) > G2 (−2.97) > G3 (−1.28) > G4 (−1.19), not observing significant statistical differences (p < 0.05) between G1 and G2 and also between G3 and G4. Conclusions: Protocols to remove photosensitizing dyes should be applied after PDT in order to minimize dental stain. The protocols tested in this study by using 2.5% NaOCl, associated or not with Endo-PTC cream, were effective in avoiding tooth staining caused by MB during PDT.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-04-15T13:34:24Z No. of bitstreams: 1 Silvio José Albergaria.pdf: 253021 bytes, checksum: 3fdb7fd466b6cafed0c85ba41b63e930 (MD5)Approved for entry into archive by Flávia Ferreira (flaviaccf@yahoo.com.br) on 2014-08-18T16:58:00Z (GMT) No. of bitstreams: 1 Silvio José Albergaria.pdf: 253021 bytes, checksum: 3fdb7fd466b6cafed0c85ba41b63e930 (MD5)Made available in DSpace on 2014-08-18T16:58:00Z (GMT).
