Background and Objective: was to compare single visit root canal treatment post- operative pain with different manual and rotary instrumentation techniques on vital teeth.

Methods and Materials: a single visit root canal treatments was performed on 34 single rooted with one canal vital teeth, 3 patients drooped of (4 teeth), and the final sample included 30 tooth.

Root canal treatment was done with different instrumentation techniques under rubber dam isolation and were randomly distributed into three groups: group 1: manual preparation Step-Back (control), group 2: manual Protaper, group 3: Rotary Protaper.

The obturation technique was lateral condensation for the three groups.

Pain was detected during the treatment and after 6, 24, 48 hours and one week, using two scales (the visual analog and descriptive scales).Results were analyzed throw SSPS 13 edition throw ANOVA and T Student tests with 95% significance level.

Results: there were no differences between the three groups regarding post-operative pain within different monitoring periods P>0.05.

Pain levels increased after 24 and 48 hours in the 3rd group (Rotary ProTaper) comparing with other monitoring periods and then decreased after a week P<0.05.

Pain almost disappeared in the three groups after one week of the treatment.

Pain levels were higher during and after 6 hours of root canal treatment in teeth that suffered from pre-operative symptoms P<0.05.

Conclusions: within the limits of this study we can conclude the following: - No relation between the root canal preparation technique (Manual or Rotary) and Pain during and after treatment.

- Post-operative pain increased clearly in rotary group and decreased almost disappearing after one week.

- There is a relation between pain incidence during treatment and appearance after 6 hours of treatment, and pre-operative symptoms.
