About

Effective intraoperative pain management is vital in paediatric dentistry, especially during vital pulp therapy (VPT) for reversible pulpitis. Although NSAIDs are widely used postoperatively, their role in controlling pain during treatment is less understood. To investigate the effect of preoperative ibuprofen on pain perception and physiological stress during VPT in children.

Full description

This prospective, randomized, controlled clinical trial will investigate the effect of preoperative ibuprofen administration on intraoperative pain during vital pulp therapy (VPT) in pediatric patients diagnosed with reversible pulpitis. The study will be conducted at the Department of Pediatric Dentistry, Faculty of Dentistry, Inonu University. Ethical approval has been obtained from the Institutional Clinical Research Ethics Committee of Inonu University (Approval No: 2024-KAEK-08; Date: 25.12.2024). Written informed consent will be obtained from the parents of all participants.

A total of 44 children aged 7 to 13 years, in good general health, with deep carious lesions in a mandibular first permanent molar and a clinical diagnosis of reversible pulpitis will be included in the study. Participants will be randomly assigned in equal numbers (n=22 per group) to the intervention and control groups using a computer-generated randomization sequence and the sealed envelope method.

Children in the intervention group will receive oral ibuprofen (10 mg/kg) 40 minutes prior to treatment. The control group will receive no preoperative medication. A single-blind study design will be employed: the clinician performing the procedures will be aware of group allocation, while the statistician responsible for data analysis will remain blinded.

All participants will receive an inferior alveolar nerve block (IANB) before the procedure. Anesthesia will be verified with a cold test, and treatment will begin only after adequate anesthesia is confirmed. All procedures will be performed by the same pediatric dentist, following a standardized clinical protocol. The specific type of VPT (protective liner, direct pulp capping, partial pulpotomy, or coronal pulpotomy) will be selected based on clinical presentation.

Intraoperative pain will be assessed using both physiological and subjective measures. Pulse rate will be continuously monitored with a fingertip pulse oximeter, with a focus on readings taken when the bur approaches within close proximity to the pulp. Subjective pain will be measured using a Visual Analogue Scale (VAS), shown to the patient at the most sensitive moment of the procedure. Postoperative VAS scores will be recorded on Days 1, 3, and 7.

---

46 participants in 2 patient groups

control group

No Intervention group

Description:

Children in this group received no preoperative medication before undergoing vital pulp therapy. Standard local anesthesia was administered prior to the procedure.

ibuprofen group

Experimental group

Description:

Children in this group received a single dose of ibuprofen (10 mg/kg) orally, 40 minutes prior to vital pulp therapy. The goal was to evaluate the effect of preoperative ibuprofen on intraoperative pain and physiological stress.

Treatment:

Drug: Ibuprofen 10 mg/kg
