To determine the effect of intraligamentary injection of Lornoxicam on the intensity of post-operative endodontic pain in the tooth with symptomatic irreversible pulpitis.

Condition Intervention Phase
Post Operative Endodontic Pain Drug: Lornoxicam Drug: normal saline Drug: no injection Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: the Effect of Intraligamentary Injection of Lornoxicam on the Intensity of Post-operative Endodontic Pain in the Tooth With Symptomatic Irreversible Pulpitis

Further study details as provided by Mandana Abedi Tari, Islamic Azad University, Tehran:

Primary Outcome Measures:
  • Post operative endodontic's pain [ Time Frame: 6,12,24,48 hours after drug's injection ]
    The measuring method of the pain is VAS(Visual Analogue Scale).

Enrollment: 60
Study Start Date: September 2011
Study Completion Date: December 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Lornoxicam Drug: Lornoxicam
PDL injection of 0/2 ml of lornoxicam (4mg/ml),before the root therapy and after the inferior alveolar injection
Other Names:
  • Xefo
  • (904111)
Placebo Comparator: normal saline Drug: normal saline
PDl injection of 0/2 ml normal saline before the root therapy and after inferior alveolar injection
Placebo Comparator: no injection Drug: no injection
inject nothing after inferior alveolar injection and before root canal therapy

Detailed Description:
sixty qualified samples (initial estimate which will be come more accurate after the pilot study on 6 patients) will be divided randomly in three groups which all of them will have an inferior Alveolar injection and before the beginning of the treatment the primary group will receive an injection of 0.4 mL ( 0.2 mL in mesio buccal and 0.2 mL in disto buccal) of Lornoxicam and the second group will be injected with 0.4 mL of normal saline( 0.2 mL in mesio buccal and 0.2 mL in disto buccal) ,in third group we will only pretend the injection but actually there is no substance injected ,making the patient believe that there was an injection . Then the patients' pain will be evaluated with visual Analogue Scale analysis (VAS) 0-170 mm in time intervals of 6, 12, 24 and 48 hours after the treatment.
