Efficacy of a Chitosan Dressing in Pulpotomy of Immature Permanent Teeth

December 31, 2025 updated by: Salsabil Mohammed Naguib, Minia University

Efficacy of a Chitosan Dressing in Pulpotomy of Immature Permanent Teeth:Randomized Clinical Trial

Immature permanent teeth, also known as young permanent teeth, are used to describe teeth with incomplete root formation. Immature permanent teeth are prone to caries and trauma which can cause exposure and degeneration of pulp. Pulp degeneration stops root formation, leaving teeth with open apex. It is vital to preserve the pulp vitality otherwise the incompletion of root might result in the fragility of teeth. Pulpotomy is one of the most widely used methods in preserving vital pulp in teeth, which is of great significance in achieving continue root formation in immature permanent teeth suffering from dental caries or trauma. Pulpotomy is recommended by the American Association of Pediatric Dentistry for the management of pulp exposure in immature permanent teeth to achieve apexogenesis (continued root formation and closure of apex). In this procedure, coronal pulp tissue is removed in order to eliminate the infected or contaminated pulp and to reach the healthy vital pulp followed by coverage with biocompatible material.

Detailed Description

Immature permanent teeth, also known as young permanent teeth, are used to describe teeth with incomplete root formation. Immature permanent teeth are prone to caries and trauma which can cause exposure and degeneration of pulp. Pulp degeneration stops root formation, leaving teeth with open apex. It is vital to preserve the pulp vitality otherwise the incompletion of root might result in the fragility of teeth. Pulpotomy is one of the most widely used methods in preserving vital pulp in teeth, which is of great significance in achieving continue root formation in immature permanent teeth suffering from dental caries or trauma. Pulpotomy is recommended by the American Association of Pediatric Dentistry for the management of pulp exposure in immature permanent teeth to achieve apexogenesis (continued root formation and closure of apex). In this procedure, coronal pulp tissue is removed in order to eliminate the infected or contaminated pulp and to reach the healthy vital pulp followed by coverage with biocompatible material.

Clinically, the characteristic and the extent of pulpal hemorrhage at the exposure site are the most important outcome predictors for assessing pulpal status.

reported that excessive bleeding from the pulp revealed a significantly lower incidence of success compared with moderate bleeding. A variety of solutions and methods have been used to obtain pulpal hemostasis. Despite its limited effect on pulpal healing, sterile saline is a frequently used agent. Sodium hypochlorite (NaOCl), in concentrations of 0.5percent, achieves hemostasis without affecting pulpal repair mechanism and healing.

Hemostatic dressings have emerged as valuable adjuncts in dentistry, offering effective and efficient control of bleeding during various dental procedures. The different types of hemostatic dressings, including oxidized cellulose, gelatin- based, chitosan, and calcium-based dressings, provide localized hemostasis, reduce chair time, and improve patient outcomes.

Recently, the concept of lesion sterilization and tissue repair therapy involve the use of a mixture of antibacterial drugs for disinfection. Repair of damaged tissues can be expected if lesions are disinfected.

Chitosan is a natural and non-toxic polysaccharide with unique biological properties such as antimicrobial, anti- fungal, anti-inflammatory, antiseptic, antitumor, hemostatic,

immune adjuvant, regenerative effect and wound healing. In dentistry, it can be used as a dental pulp capping material, mouth rinse, chewing gum, drug device for root canal disinfection, topical treatment of periodontitis and blood hemostasis after tooth extraction.

Chitosan is the most abundant biopolymer on the earth derived from chitin. It shows a remarkable effective broad spectrum antibacterial action attributed to its cationic nature. It interacts with the -ve charged bacterial cell membranes, leading to leakage of the intracellular constituents and ultimately cell death due to increasing the membrane permeability. Also, chitosan possesses a variety of other biological properties as being biodegradable, biocompatible.
