Abstract:
Postoperative pain after endodontic procedures is an undesirable occurrence for both patients and clinicians. Certain factors may predispose to the development of postoperative pain. Knowledge of the causes and mechanisms behind interappointment pain in endodontics is of utmost importance for the clinician to properly prevent or manage this undesirable condition. The causative factors of interappointment pain encompass mechanical, chemical, and microbial injuries to the pulp or periradicular tissues, which are induced or exacerbated during root canal treatment. Ninety patients were recruited and included in this study out of one hundred and twenty patients, those patients requiring endodontic treatment on their permanent upper or lower molar teeth with asymptomatic irreversible pulpitis preoperatively, access opening and instrumentation was performed at the same visit.Patients ranged in age from 19 to 50 years old, and all were in good health, as determined from a written health history and oral interview.The patients were assigned randomly into three groups of 30 patients each : ? First group (n=30) : Teeth were instrumented using Universal ProTaper System (Full Rotary technique).? Second group (n=30) : Teeth were instrumented using ProTaper Next System (Full Rotary technique).? Third group (n=30) : Teeth were instrumented using WaveOne System (Reciprocating technique).Pain assessment carried out at day 1, 2, 3 & 7 using Verbal Rating Scale (4 - Point Scale). Patients recorded the incidence and severity of pain experienced.Patients were called at 24, 48 and 72 hours to obtain their reports for the first three days. Seven days after treatment their records were reviewed and percussion test was performed. Result showed that all groups induced Post - operative Pain, the difference is some systems cause more Post - Operative pain than other do : group 3 (WaveOne group) showed higher incidence and severity of PostoperativePain, followed by group 1 (Universal ProTaper group) that has shown less incidence and severity of Post - operative Pain than group 3 (WaveOne group), last group which it was group 2 (ProTaper Next group) has shown the lowest incidence and severity of Post - operative Pain. The data obtained were analyzed statistically using Chi Square test, total score for Verbal Rating Scale at day 1, 2, 3, and 7 showed that there was a highly significant differences between ProTaper Next group and other twogroups (P ? 0.001), and non - significant differences between ProTaper group and WaveOne group (P ? 0.05).
