Effects of Different Irrigation Solutions on the Chemical Composition of Multi-Root Canals of Radicular Dentine in Upper Premolar Teeth

The objective of this research was to assess the effects several irrigation solutions (ISOLs) on two major (P and Ca) some minor (Fe, Zn, Sr) elements multi-root canals radicular dentin in upper premolar teeth using X-ray fluorescence analysis (XRF). Powder fifty specimens were prepared divided into five groups based treatments with different single combined ISOLs. These were: G1-distilled water (control); G2- sodium hypochlorite (NaOCl, 5.25%); G3- 5.25%) ethylendiaminetetraacetic acid (EDTA, 17%); G4- distilled a mixture tetracycline, an acid, detergent (MTAD); G5- 1.3%) MTAD. XRF results confirmed that ISOL G5 (Ca/P=1.6254) most effective one. ratio-to-ratio correlations revealed common origins Fe, Sr root dentin, which highly interacted P Ca each. interactions insignificantly affected by used Finally, is recommended as safe, fast, nondestructive, relatively not expensive technique analyze endodontic therapy teeth.
