AIM To microscopically examine the cleanliness of root canal walls that remained unprepared as revealed by micro-CT. METHODOLOGY The root canals of 10 freshly extracted mandibular premolars with necrotic pulps and apical periodontitis along with the mesiobuccal canals of 11 mandibular molars with vital pulps were prepared using Reciproc instruments R40 and R25, respectively, and 2.5% sodium hypochlorite irrigation. Specimens were scanned in micro-CT before and after preparation, and the… CONTINUE READING
