Buffered Versus Conventional Local Anesthesia for Pain and Anxiety Reduction in School-Aged Children With Pulpitis
Mexico60 participantsStarted 2026-03-02
Plain-language summary
The objective of this clinical trial is to evaluate whether buffered local anesthesia is more effective than conventional local anesthesia in reducing pain responses in school-aged children requiring dental treatment for pulpitis. The study will also assess differences in physiological and self-reported indicators of pain and anxiety, as well as anesthetic onset and duration.
The main questions it aims to answer are:
Does buffered local anesthesia reduce behavioral pain scores measured by the FLACC scale compared to conventional local anesthesia? Does buffered local anesthesia improve physiological and psychometric indicators of pain and anxiety during dental procedures?
Methodology: The researchers will compare buffered local anesthesia with conventional local anesthesia during routine dental treatment procedures such as pulpotomy or pulpectomy in primary molars.
Participants will:
Receive either buffered or conventional local anesthesia during dental treatment Undergo pulpotomy or pulpectomy depending on clinical diagnosis Be monitored for pain and anxiety using FLACC scale, heart rate, skin conductance, and Wong-Baker Faces Pain Scale at different stages of treatment Have the onset and duration of anesthesia recorded during and after the procedure Be followed until recovery of soft tissue sensation after treatment

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
