NCT06809478

Brief Summary

The goal of this clinical trial is to evaluate whether Chitosan liquid will show similar clinical and radiographical success rate compared to Formocresol when used in vital pulp therapy in primary molars. The main question it aims to answer is:

  • Will Chitosan liquid, in comparison to Formocresol, show similar clinical outcomes in relation to presence/absence of post-operative pain, swelling, sinus and/or fistula formation when used in vital pulpotomy in primary molars?
  • Will Chitosan liquid, in comparison to Formocresol, show similar radiographical outcomes in relation to presence/absence of furcal involvement, periapical lesion, pathological root resorption and/or widening of periodontal membrane space when used in vital pulpotomy in primary molars? Following conventional pulpotomy procedure, the primary investigator will evaluate the effect of placing a cotton pellet damp with Chitosan liquid directly on radicular vital pulp compared to that of placing a cotton pellet damp with Formocresol on radicular vital pulp. Primary teeth included in both arms of the study will be restored by zinc oxide and eugenol and covered by a stainless steel crown as final restoration. The clinical trail will be followed up for 1 year. Clinical outcomes will be evaluated every 3 months. Radiographic outcomes will be evaluated every 6 months.

Study Arms (2)

Pulpotomy using Chitosan

EXPERIMENTAL

Chitosan is a natural cationic polysaccharide polymer obtained from chitin deacetylation. It is a linear biopolymer consisting of 2-amino-2-deoxy-β-D-glucose (60-100%) and 2-acetamino -2-deoxy-β-D-glucoside (0-50%) bound together by ß (1→4) bonds. It is biocompatible and has antibacterial, anti-inflammatory and hemostatic properties.

Procedure: Pulpotomy using Chitosan liquid

Pulpotomy using Formocresol

ACTIVE COMPARATOR

Buckley's formocresol is composed of 31% water base, 15% glycerin to prevent formaldehyde from polymerizing to paraformaldehyde, 19% formaldehyde as an alkylating agent, and 35% tricresol as a protein-coagulating phenolic substance. A 1:5 concentration of Buckley's formocresol is used in this trial.

Procedure: Pulpotomy using Formocresol

Interventions

1. After complete hemostasis, a cotton pellet damp with chitosan liquid will be applied and gently placed over the pulp stumps for 5 minutes and removed. Then, a thick mix of zinc oxide and eugenol will be placed and gently condensed into the pulp chamber by a moistened cotton pellet. 2. Tooth will be restored with stainless steel crown.
