This study compares the clinical and radiographic effectiveness of Biodentine and Calcium Hydroxide as indirect pulp capping materials in mature permanent teeth with reversible pulpitis. A total of 76 patients were randomly assigned to two groups. Outcomes were assessed over 12 weeks based on pain, periapical radiolucency, and PDL widening. The goal was to determine which material better preserves pulp vitality
Introduction:
Preservation of pulp vitality is critical for the long-term health and functionality of teeth. The pulp can be compromised due to caries, trauma, or iatrogenic factors. One conservative treatment to preserve pulp vitality in teeth with deep carious lesions and reversible pulpitis is indirect pulp capping (IPC).
Traditionally, Calcium Hydroxide (Ca(OH)â‚‚) has been the gold standard material for IPC due to its antibacterial properties and its ability to stimulate the formation of reparative dentin. However, it has several limitations such as poor bonding to dentin, high solubility, and low mechanical strength, which may affect long-term success.
Biodentine, a newer bioactive dentin substitute, has emerged as a potential alternative due to its biocompatibility, bioactivity, antibacterial effect, good sealing ability, and high compressive strength. These properties suggest Biodentine may offer superior clinical outcomes in preserving pulp vitality when used as an indirect pulp capping material.
Objective:
To compare the clinical and radiographic effectiveness of Biodentine versus Calcium Hydroxide as indirect pulp capping agents in mature permanent teeth with reversible pulpitis.

2 weeks
6 weeks
12 weeks
Evaluation Criteria:
Clinical Parameters:
Pain (reversible or persistent)
Tenderness to percussion
Response to pulp vitality tests
Radiographic Parameters:
Presence or absence of periapical radiolucency
Periodontal ligament (PDL) space widening
Data Collection Tool:
Data was recorded using a structured proforma (Annexure-C), documenting all clinical and radiographic parameters at baseline and follow-up intervals.
Statistical Analysis:
Software: SPSS Version 26
Quantitative Variables: Mean ± standard deviation (e.g., age, weight)
Qualitative Variables: Frequency and percentage (e.g., pain, radiographic changes)
Test Used: Chi-square test
Level of Significance: p < 0.05 considered statistically significant
Ethical Considerations:
Approved by Institutional Review Board (IRB) and College Ethical Committee
Written informed consent obtained in both English and Urdu
Patient confidentiality strictly maintained
Participants allowed to withdraw at any time without affecting treatment
Budget and Funding:
Funded by Dental College, HITEC-IMS, Taxila
No financial burden on participants
Estimated duration for study completion: 1 year
Expected Outcome:
The study aims to determine whether Biodentine, with its superior physical and biological properties, provides better clinical and radiographic outcomes in indirect pulp capping procedures compared to Calcium Hydroxide in mature permanent teeth.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Biodentine Group | Experimental | Participants receive Biodentine as the indirect pulp capping material |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Biodentine - Indirect Pulp Capping | Procedure | Caries removal under rubber dam isolation using round bur (#BR-45) and water spray Tooth disinfection with 0.2% chlorhexidine Mixing of Biodentine (Septodont, France) in an amalgamator (30 seconds at 4000 rpm) Placement of Biodentine into the prepared cavity using an amalgam carrier and condensation After 1 week: Placement of self-cure GIC (Fuji, Japan) as a base Final restoration with light-cure composite resin Follow-up at 2, 6, and 12 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Radiographic assessment by Periapical Index (PAI) | PAI Scoring Criteria: Score Radiographic Features Interpretation
Application in my Study: At each follow-up (2, 6, 12 weeks), periapical radiographs should be: Evaluated using the PAI score Compared to baseline radiographs Scores ≤2 are generally considered favorable outcomes Scores ≥3 indicate disease or failure | Follow-up Timeline for Each Patient: Patients will be evaluated at the following intervals after the indirect pulp capping procedure: Baseline (Initial Treatment) 2 weeks follow-up 6 weeks follow-up 12 weeks follow-up |
| Visual Analog Scale (VAS) for Pain Measurement | 1. Pain Assessment Type: Spontaneous or provoked Tool: Patient history and Visual Analog Scale (VAS) for Pain Measurement Classification: No pain Mild/transient pain (indicative of successful pulp healing) Moderate to severe pain (suggestive of pulpal inflammation or failure) Interpretation: Absence of pain considered a positive outcome. Persistent or worsening pain may indicate treatment failure or progression to irreversible pulpitis Visual Analog Scale (VAS) for Pain Measurement Description: A 10 cm horizontal line representing a continuum of pain intensity. One end (0 cm) represents "No pain", and the other end (10 cm) represents "Worst possible pain". Scoring Criteria: VAS Score (cm) Pain Intensity 0 No pain 1-3 Mild pain 4-6 Moderate pain 7-10 Severe pain Application in my Study: Patients can be asked to mark their pain level on the scale at: Baseline 2-week 6-week 12-week follow-up visits | Patients pain level can be measured on the scale at: Baseline 2-week 6-week 12-week follow-up visits |
| Tenderness to Percussion | 2. Tenderness to Percussion Tool: Blunt end of dental mirror gently tapped on the occlusal surface Response Categories: Absent: No discomfort or pain on percussion (favorable response) Present: Pain on percussion, indicating potential periapical inflammation or pulp degeneration Interpretation: Lack of tenderness is a favorable clinical outcome. Positive percussion response may suggest underlying periapical involvement or pulpal pathology. |
