AB  - OBJECTIVE: The aim of this study was to evaluate the effect of photodynamic 
      therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in 
      root canals. MATERIAL AND METHODS: Sixty single-rooted premolars were used. The 
      teeth were prepared using a crown-down technique. NaOCl and EDTA were used for 
      irrigation and smear layer removal, respectively. The root canals were divided 
      into three groups: control, PDT, and NTP. After treatments, the roots were filled 
      using gutta-percha and either AH Plus (AHP) or MTA Fillapex (MTAF) sealers. 
      Samples were sectioned at 4, 8, and 12 mm from the apex (1-mm slices)and analyzed 
      by the push-out bond strength test (adhesion) and confocal laser scanning 
      microscopy (sealer penetration). Data were statistically evaluated using 
      Kruskal-Wallis, Dunn's, and Spearman's tests. RESULTS: Regarding AHP, bond 
      strength was similar in the NTP group and in the control group, but significantly 
      lower in the PDT group. As to MTAF, both therapies showed lower values than the 
      control group. In the confocal analysis of AHP, maximum and mean penetration, and 
      penetrated area were statistically higher in the control group than in the PDT 
      and NTP groups. Penetrated perimeter was similar among groups. Regarding MTAF, 
      all parameters yielded better results in the NTP than in the control group. The 
      PDT and control groups showed similar results except for penetrated area. 
      CONCLUSION: PDT and plasma therapy affected the adhesion and sealer penetration 
      of root canals filled with AH Plus and MTA Fillapex and there is no positive 
      correlation between adhesion and sealer penetration.
