Abstract :

Aim: The aim of this study was to compare the efficacy of six techniques for placement of calcium hydroxide intracanal medicament into the root canal system. Materials and methods: Total 30 extracted human mandibular premolars were decoronated to standardize the root length and subsequently prepared with Heroshaper rotary file system upto file 25 4%. After cleaning and shaping of the canals the roots were divided into six groups on the basis of six insertion techniques for calcium hydroxide paste: group 1: conventional technique using handfiles (MAN); group 2: rotary lentulo spirals; group 3: combination of handfile and sonic activation through EndoActivator (EA), group 4: sonic devices MM sonic (Micromega), group 5: Gutta Percha cones and group 6: Pastinject (Micromega). The quality of calcium hydroxide fillings in the root canal system was evaluated at coronal, middle and apical third of the canal with the help of NNT viewer software of CBCT. Result: In general, calcium hydroxide paste was nearest to the apex in MM sonic and Endoactivator groups as compared to other groups. Conclusion: the present study results showed that sonic devices used in the present study provide a superior coating of calcium hydroxide intracanal medicament than other techniques used
