ABSTRACT

Objectives: The Aim Of This Prospective Randomized Clinical Trial Was To Compare The Degree Of Post-operative Pain And Analgesic Intake At 0, 4, 12, 24, 48, 72-hrs And 7 Days After The Use Of Two Different Irrigation Needles. Subjects And Methods: Thirty Eight Participants Diagnosed With Symptomatic Or Asymptomatic Irreversible Pulpitis In Mandibular Posterior Teeth Received Single-visit Root Canal Treatment And Were Divided Randomly Into Two Groups According To The Type Of Needle Used During Irrigation Either NaviTip 29-gauge, 27 Mm With End-Vented Needle (EVN) Or NaviTip 31-gauge, 27 Mm With Double Sideport Irrigator Tip (SVN). Post-operative Pain Was Measured Using Numeric Rating Scale (NRS) Pre-operatively, Immediate Post-operatively And At 4, 12, 24, 48, 72-hrs And 7 Days. Placebo And Analgesic Intake Was Recorded At The Different Time Intervals.

Results: There Was No Difference Between Both Groups In The NRS Scores At All The Post-operative Time Intervals. An Observable Increase In Pain Levels Was Recorded At 4-hrs Followed By An Observable Drop In Pain Levels At 12, 24 And 48-hrs Post-operatively Until Pain Disappeared At 7 Days With No Difference In Drug Intake Post-operatively Between Both Groups.
