An In Vivo Comparative study To Evaluate Postopexetive Pain After Root Canal Treatment Using Three Different Filling Techniques

Post-obturation pain is one of the primary problems following root canal treatment. Although in most cases pain does not last long, but could be a source of embarrassment to the dentist and annoying for the patient. This study was conducted to investigate and compare the incidence of postoperative pain after one-visit root canal treatment (RCT) on teeth with vital pulps using three different obturation techniques. 90 cases were assigned into three treatment groups, each group 30 cases(10 anterior, 10 premolar, 10 molars), The canals of all teeth were prepared using Protaper rotary system and then filled at the same visit using one of the three obturation techniques (lateral condensation technique, HEROFILL technique, E&Q PLUS technique). The postoperative pain was recorded on a visual analogue scale (VAS) of 0 - 100 after 2 hours, 24 hours, 48 hours and 7 days.

Simulated in-vivo effect of root canal filling pastes of primary teeth on Enterococcus Faecalis biofilm

Enterococcus faecalis is associated with different root canal infections, and it is the main cause of chronic periapical lesions farthermore , it is difficult to eliminate from root canal in one visit or more, so The aim of this study was to isolate E. faecalis from asymptomatic necrotic root canals of primary teeth
