Purpose: To evaluate the cleanliness of post space walls after using two different post space preparation (PSP), and three different root canal wall cleaning techniques.
Methods: 104 mandibular premolars were selected. After root canal preparation, specimens were divided into two groups (n = 52) for PSP treatment: conventional post space preparation (CPSP), and modified post space preparation (MPSP). Four subgroups (n = 13) were defined based on the cleaning method: control, SAF, PUI, and PIPS. Micro (µ)-CT scans of the teeth were performed before and after the post space cleaning techniques. Remaining residue volumes were measured to calculate cleaning percentages (%).
Results: After first µ-CT scan, there was a significant difference between CPSP and MPSP (P < 0.05). In both PSP techniques, significant differences were observed among the irrigation procedures (P < 0.05). Cleaning efficiency was highest for SAF in group CPSP, and PIPS in group MPSP (P < 0.05). Pairwise comparisons revealed a residue volume similarity between same cleaning techniques of the PSP groups (P > 0.05), except for the PIPS technique (P < 0.05).
Conclusion: CPSP could be preferred over the MPSP in clinical practice because it removed more residue. PIPS and SAF were more effective than PUI.
