Predicting Vital Pulp Treatment Outcomes in Symptomatic Pulpits Using Metabolic Biomarker

March 26, 2026 updated by: Abeer Ghalib Abdul-khaliq

Efficacy of Metabolic Biomarkers in Predicting Twelve-Month Outcomes of Vital Pulp Treatment in Symptomatic Teeth With Carious Pulp Exposure: A Controlled Clinical Trial

This prospective controlled clinical trial investigates whether metabolic biomarkers measured in pulpal blood at the time of carious pulp exposure can predict the 12-month outcomes of vital pulp treatment in symptomatic permanent teeth. Eligible patients aged 16-50 years presenting with deep carious pulp exposure will undergo vital pulp therapy (partial pulpotomy or full pulpotomy). Pulpal blood samples will be collected at the time of exposure and analyzed using High-Performance Liquid Chromatography (HPLC). Treatment outcomes will be assessed clinically and radiographically at 12 months. The study aims to identify objective, measurable biomarkers that can improve pulpal diagnosis and guide clinical decision-making in vital pulp therapy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Vital Pulp Treatment (VPT)
Participants with symptomatic teeth and carious pulp exposure will receive vital pulp treatment after caries removal. The specific procedure will be determined intraoperatively based on clinical criteria. Pulpal blood samples will be collected for metabolic biomarker analysis, followed by placement of a calcium silicate- based material and definitive restoration. Clinical and radiographic outcomes will be assessed over 12 months.
Vital pulp treatment (VPT) is defined by the European Society of Endodontology as a group of biologically based procedures aimed at preserving the health and function of the dental pulp that has been exposed or is at risk of exposure. These procedures involve removal of infected or inflamed tissue where necessary, protection of the remaining vital pulp with a biocompatible material, and placement of a definitive restoration to achieve a hermetic seal and support healing.

Plan to Share Individual Participant Data (IPD)?

NO

IPD Plan Description

Individual participant data will not be shared due to ethical and privacy considerations. The study involves collection of biological samples (pulpal blood) and clinical data from patients at the University of Baghdad College of Dentistry. Participant confidentiality is protected under the terms of the signed informed consent forms, which do not include provisions for third-party data sharing. Additionally, as this is a PhD research protocol conducted within an institutional academic setting, data governance policies of the University of Baghdad restrict the external sharing of raw participant-level data. Summary-level findings will be disseminated through peer-reviewed publication.
