Check pulpal response using EPT/Cold Test at intervals of 1 week, 3 months and 6 months post-procedure.

Overview

Brief Summary

This clinical trial will be conducted in the Department of Conservative Dentistry and Endodontics, Himachal Dental College & Hospital, Sundernagar, Himachal Pradesh.

After obtaining informed consent from the patients (Annexure I attached), they will be randomly allocated into three groups:

Group A: Calcium Hydroxide

Group B: Bio-C Repair

Group C: Calcimol LC

For the purpose of the clinical trial, the pulpal response using Electric Pulp Test (EPT) and cold test will be recorded as a baseline reference.

If required (in cases of severe sensitivity during cavity preparation, rinsing, or in patients with dental phobia), the tooth will be anesthetized using 2% lignocaine containing 1:80,000 adrenaline. Isolation of the tooth will be achieved using a rubber dam.

A sterile diamond bur will be used in a high-speed handpiece under constant water spray. Carious tissue will be identified and removed with the aid of a caries detector dye. The dye will be applied to cavity walls to stain demineralized carious tissue, allowing precise identification of infected dentine.

Stained, demineralized tissue will be removed, starting from the peripheral walls toward the center of the lesion. Selective caries removal will be done carefully to reach relatively firm, non-stained dentine. This step will be guided by both visual and tactile feedback to avoid accidental pulp exposure.

Necrotic carious fragments will be removed with a spoon excavator, followed by a round bur in a low-speed handpiece with water cooling. A fresh sterile bur will be used in deeper areas of the lesion to reduce microbial contamination and prevent the introduction of infected dentine into the pulp.

The prepared cavity will be rinsed with normal saline to remove residual dye and then gently dried.

Pulp capping material (based on group allocation) will be applied to the cavity floor. This material will be covered by a layer of Glass Ionomer Cement (GIC).

Subsequently, the cavity will be restored with composite resin.

Pulpal response using EPT and cold test will be evaluated at 1 week, 3 months, and 6 months post-procedure for follow-up and clinical assessment.
