Arslan, E. Effect of Phytic Acid Used with Different Irrigation Techniques on Bond Strength of Epoxy Resin and Calcium Silicate Based Root Canal Filling Materials to Root Canal System. Hacettepe University Faculty of Dentistry Department of Endodontics, Specialization Thesis, Ankara 2018. The aim of this study was to evaluate the effect of phytic acid activated with different irrigation techniques on push-out bond strength of epoxy-resin based [AH Plus (DENTSPLY DeTrey, Konstanz, Germany)] and calcium silicate based [NeoMTA Plus (Avalon Biomed Inc, Bradenton, Florida, USA)] root canal materials. In the present study totally 128, freshly extracted, single-rooted human teeth were used. After crown removal, root canals were instrumented by using ProTaper Universal (Dentsply Maillefer, Ballaigues, Switzerland) rotary nickel-titanium system up to F3. The teeth were randomly divided into 2 subgroups according to the final irrigation solutions as follows: 1) 17% EDTA (ENDO-SOLution, Cerkamed, Nisko, Poland) and 2) 1% Phytic acid (Sigma Aldrich, Saint Louis, USA) (n=64/group). Then, these 2 groups were randomly divided into 4 subgroups according to the final irrigation techniques as follows: 1) Standard technique, 2) Sonically 3) Ultrasonically 4) Laser activated irrigation (n=16/group). After irrigation and drying the groups were randomly divided into two groups according to the root canal sealers as follows: 1) AH Plus 2) NeoMTA Plus (n=8/group). The push-out bond strength test was performed using universal test machine (Lloyd LRX; Lloyd Instruments Ltd, Fareham, UK). Data were statistically evaluated using three-way ANOVA and Games-Howell post-hoc tests. According to the bond strength results, no statistically significant differences were observed between irrigation techniques and root canal sealers (p>0.05). The groups used with phytic acid presented statistically higher bond strength values than EDTA (p<0.05). Phytic acid revealed favorable results and therefore, could be suggested as alternative to EDTA during root canal treatment.
