“…The results of the present study suggest that maintaining the presence of one of the chelating solutions in root canals during instrumentation with Reciproc instruments is beneficial. Previous studies stated that using either rotary full-sequence or reciprocating single-file instruments with EDTA gel (10,11) or the presence of RC Prep (containing EDTA, Well-Prep, Vericom Co., Anyang, Republic of Korea) (9) in root canals did not reduce crack formation. In the present study, chelating agents resulted in a lower number of cracked sections than that following the use of NaOCl or distilled water.…”

The present study aimed to evaluate the degree of crack formation during canal preparation using reciprocating files. A total of 120 incisor teeth were divided into eight groups according to irrigation protocol (n = 15). The irrigation solution and chelating agents included distilled water, sodium hypochlorite (NaOCl), citric acid, maleic acid, peracetic acid, ethylenediaminetetraacetic acid (EDTA) gel, and EDTA liquid. The root canals were prepared using reciprocating instruments while one of the agents was present within the root canals. A control group was subjected to neither preparation nor irrigation. The roots were horizontally sectioned 3, 6, and 9 mm away from the apices. The numbers of cracks were recorded. Statistical analyses were performed using a chi-squared test. The chelating agents resulted in similar numbers of cracked sections. The use of one of the chelating agents during preparation using reciprocating instruments appears to be beneficial in reducing crack formation.
