Official Title: Incidence of Post-Operative Pain After Single Visit Root Canal Treatment in Necrotic Teeth Using Two Different Rotary Systems (Protaper Nex t& Neolix File)

Brief Summary: this prospective in vivo randomized clinical is to evaluate the post operative pain (incidence ,degree and duration) with multiple full rotation file (protaper next ®) and single full rotation file (Neolix®) in treating maxillary and mandibular anterior and premolar with chronic pulpitis .Together with our aim from this trial ; we are trying to provide an evidence for the dentists in order to provide the best quality service with the least expenses and thus gaining the patients' trust and saving time, money and effort.

Detailed Summary:

Interventions:

Using neolix file (Ori kam SAS,France)

Control:

Using Protaper next files (Dentsply ,Maillefer , Switzerland)

Treatment in all cases will be completed in one session as follows:

  • Full medical and dental history using a schematic dental chart will be obtained from all patients treated during this study. Each tooth will be evaluated for vitality (sensitivity) of pulp tissues using electric pulp tester (Kerr, Analytic Technology Crop, Redmond, WA).
  • Patient will be anesthetized; teeth will be isolated with rubber dam.
  • Make access and working length will be determined using an electronic apex locator (Root ZX, J.Morita USA, Irvine, CA.) then confirmed with intraoral periapical radiograph, to be 0.5-1 mm, shorter than radiographic apex.

  • Cleaning and shaping will be done using crown down preparation technique with rotary files either
