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
