Official title
Efficacy of Buffered Versus Conventional Local Anesthesia for Reducing Pain and Anxiety During Dental Treatment in School-Aged Children Diagnosed With Pulpitis: A Randomized Controlled Clinical Trial
Overview
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
Interventions
- Drug Buffered Lidocaine with Epinephrine
Local anesthetic solution buffered with sodium bicarbonate prior to administration in order to increase pH and potentially improve onset and patient comfort during dental procedures. - Drug idocaine with Epinephrine (Conventional)
Standard commercially available local anesthetic solution used in routine dental practice without pH modification
Primary outcome measures
- FLACC PAIN SCORE [Time frame: Baseline (before local anesthetic administration), during anesthetic injection, cavity access (pulpotomy/pulpectomy), and final restoration phase (immediately during procedure)]
Secondary outcome measures (5)
- Physiological indicators (Heart Rate) [Time frame: Baseline, during anesthetic injection, cavity access (pulpotomy/pulpectomy), and final restoration phase (immediately during procedure)]
- Physiological indicators (Skin Conductance) [Time frame: Baseline, during anesthetic injection, cavity access (pulpotomy/pulpectomy), and final restoration phase (immediately during procedure)]
- Wong-Baker Faces Pain Rating Scale Score [Time frame: Baseline (before local anesthetic administration, during anesthetic injection, cavity access (pulpotomy/pulpectomy), and final restoration phase (immediately during procedure)]
- Onset of local anesthesia [Time frame: From completion of anesthetic injection until confirmation of pulpal anesthesia during the treatment visit.]
- Duration of soft tissue anesthesia [Time frame: From confirmation of soft tissue anesthesia immediately after injection until complete recovery of sensation, assessed up to 6 hours after treatment.]
