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-h 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 Side-port 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-h And 7 Days. Placebo And Analgesic Intake Was Recorded At The Different Time Intervals.

Results: There Was A Statistically Significance Difference In Post-operative Pain Between Both Groups At 12, 24, 48 And 72-h Post-operatively. A Significant Increase In Pain Level Was Recorded After 4-h Compared To The Immediate Post-operative In The End-vented Needle Group, Followed By A Gradual Decrease In Pain Levels Until Pain Disappeared At 7 Days With No Difference In Medication (placebo And/or Analgesic) Intake Post-operatively Between Both Groups.
