About this study
Official title: 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
vital pulp treatmentProcedure or surgery
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.
| Study group | Role | What they receive |
|---|---|---|
| Vital Pulp Treatment (VPT) | Experimental | 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. Receives: Procedure: vital pulp treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pulp survival: is overall clinical success at 12 months
Pulp survival: is overall clinical success at 12 months, defined according to COS-ENDO domains as the absence of patient-reported pain, absence of clinical signs of infection, maintenance of normal periradicular status radiographically, preservation of functional tooth structure, and no need for further intervention.
Measured: From enrollment to the end of 12 months follow-up

What does the primary outcome measure?
Pulp survival: is overall clinical success at 12 months (time frame: From enrollment to the end of 12 months follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07452614, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
