Post-operative Pain Following Glide Path Preparation Using Rotary Neoniti GPS File and Manual K-files

Post-operative Pain Following Glide Path Preparation Using Rotary Neoniti GPS File and Manual K-files in Non-vital Lower Molars: A Randomized Controlled Trial

The aim of this study is to clinically compare the incidence of post-operative pain after using rotary glide path file (Neoniti GPS), on post-operative pain when compared to manual glide path preparation in lower molars with asymptomatic non-vital pulp.

Inclusion Criteria:

1. Systemically healthy patients (ASA I or II)
2. Lower permanent molar teeth with:

Asymptomatic non-vital pulps, No response of pulp tissue to cold pulp tester (ethyl chloride spray), with or without periapical lesions.

Exclusion Criteria:

1. Medically compromised patients having significant systemic disorders. (ASA III or IV).
2. History of intolerance to NSAIDS.
3. Patients with two or more adjacent teeth requiring endodontic treatment.
4. TMJ problems, bruxism, clenching or traumatic occlusion.
5. Inability to perceive the given instructions.
6. Teeth with:

Vital pulp tissues. Association with swelling. Acute periapical abscess. Mobility Grade II or III. Pocket depth more than 5mm. Previous root canal therapy. Non-restorability.
