Photodynamic therapy
Convencional endodontic treatment for deciduous teeth, with Surgical chemical preparation with series of Kerr files appropriate for each case, using initial file and an additional two files of larger size, with irrigation and aspiration with 1% sodium hypochlorite (Milton's solution) and endo PTC (Fórmula & Ação) with each change of file. Filling of root canals with calcium hydroxide (Ultra-cal, Ultradent, Brazil); base of thin gutta-percha and filling with glass ionomer cement; restorative treatment performed in subsequent session.
Endodontic Treatment with photodynamic terapy Irrigation of the root canal system Insertion of sterile paper cone immersed in Chimiolux® methylene blue for three minutes; administration of wireless Therapy XT EC laser device (DMC - São Carlos, Brazil) after removal of cone; energy density: 4 J/cm², power: 100 mw; wavelength: 660 nm; exposure time: 40 seconds Filling of root canals with calcium hydroxide (Ultra-cal, Ultradent, Brazil); base of thin gutta-percha and filling with glass ionomer cement; restorative treatment performed in subsequent session
