Abstract：AIM:To evaluate the apical sealing ability of iRoot SP and AH-Plus in oval shaped canals. METHODS:40 recently extracted human premolars with single oval canal were divided randomly into 2 experimental groups (n=1 5 )and positive and negative control groups (n=5 ).The root canals were instrumented using Reciproc file to 0.06 taper,#40,and were obturated with iRoot SP with single -cone obturation technique (group iRoot SP) and AH-Plus with single-cone obturation technique (group AH-Plus)respectively.The apical microleakage was eval-uated by dye penetration method.Linear dye penetration was measured and analyzed by SPSS 1 3.0 software package. RESULTS:Mean depth of leakage of iRoot SP and AH-Plus group was(2.27 ±0.72)mm and (2.68 ±0.75)mm re-spectively(P>0.05),that of positive and negative control group was(1 1 .75 ±0.72)mm and 0 respectively.CON-CLUSION:iRoot SP has similar apical sealing ability to AH-plus when using a single-cone obturation technique in o-val canals.
