Background: Calcium hydroxide (Ca(OH)2) has been shown to be an effective intracanal medicament during endodontic therapy. Aim of the study: To comparatively analyze the efficacy of manual and ultrasonic technique for removal of Calcium Hydroxide medicament from root canals. Materials and methods: On comparing the gray values before application and after application, there was a statistically significant difference which means after removal of CaOH2 from the canals, the canals did not attained its previous empty state. This difference was observed in both the techniques used. We observed that the difference was statistically non-significant between both the techniques. Results: We selected 30 extracted mandibular canines. Teeth with incompletely formed apex and having morphological and structural anomalies were excluded from the study. The root canals were prepared using NiTi rotary files at standardized canal length of 21 mm. After completion of canal preparation, canals were filled with Calcium Hydroxide (CaOH2).  Evaluation of the quality of filling was assessed by radiographs. After sealing the access cavity, the teeth were placed in an incubator at 370C for 30 days. After 30 days, teeth were removed from incubator and were divided into two groups, Group 1 and Group 2 based on the method of removal of CaOH2 from the canal. The optical thickness of radio opaque area was recorded in view of a size of 256 conceivable shades of grey, with dark symbolizing zero and white symbolizing 255. Conclusion: Within the limitations of current study we conclude that both the techniques are efficient in eliminating calcium hydroxide properly from the root canals.
