The Impact of Using Different Final Irrigation Modes on Postoperative Pain Following Root Canal Treatment of Non-vital Mandibular First Molar With Periapical Lesion.
Necrotic Pulp With Symptomatic Apical Periodontitis
Investigational drug(s) / intervention(s)
root canal treatment
root canal treatment: single visit root canal treatment with final irrigation protocol according to arm
Study summary
The goal of this clinical trial is to learn which rinsing of root canals method works best to lower pain after a root canal in adults. The study focuses on participants aged 20 to 40 with an infection in a lower back tooth (mandibular first molar) and a small area of bone loss at the root tip.
The main questions it aims to answer are:
Does the type of tool used to rinse the tooth root canal change how much pain a participant feels after treatment?
Does the cleaning method lower the number of painkillers a participant needs to take?
Researchers will compare four different rinsing tools-ranging from a standard needle to advanced vacuum and vibration devices-to see if using suction and sound waves can lower pain levels.
Participants will:
Receive a complete root canal treatment in a single visit
Be randomly assigned to one of four cleaning groups (standard rinse, vibration, vacuum, or a combination of both)
Rate their pain on a scale of 0 to 10 at five specific times: before the visit, and at 6, 12, 24, and 48 hours after treatment
Record how many painkiller tablets (Ibuprofen) they take during the two days following the procedure

Primary outcome measure(s)
postoperative pain — Before treatment, 6 hours after treatment, 12 hours after treatment, 1 day after treatment, 2 days after treatment. modifies visual analog scale (vas) with values from 0 to 10, where 0 value means no pain and 10 means worst pain and 6 faces describing the comfort, where the first face means "does not hurt" up to the last face "hurts worst"
