Interventions

Using ultrasonic-activated sodium hypochlorite in the canals of primary molars can significantly enhance root canal disinfection by improving the irrigant's penetration and effectiveness. Primary molars often have complex and irregular canal anatomies, which can limit the reach of traditional irrigation methods. Ultrasonic activation creates acoustic streaming and cavitation effects, allowing sodium hypochlorite to better dissolve organic tissue and disrupt bacterial biofilms, especially in hard-to-reach areas. This leads to more thorough cleaning, reduced microbial load, and potentially better clinical outcomes in pediatric endodontics

Intervention group 1

using ultrasonic-activated saline within the canals of primary teeth lies in its ability to enhance mechanical debridement and improve irrigation effectiveness without the risks associated with stronger chemical agents. Although saline lacks inherent antimicrobial properties, ultrasonic activation generates acoustic streaming and cavitation, which help dislodge debris, disrupt biofilms, and clean intricate canal anatomy more efficiently than passive irrigation. This makes it a safer alternative in pediatric patients, minimizing the risk of cytotoxic effects or damage to developing permanent tooth buds while still improving cleaning outcomes.

Intervention group 2

using sodium hypochlorite (NaOCl) within the canals of primary molars is its excellent antimicrobial and tissue-dissolving properties, which are essential for effective root canal disinfection. Primary molars often have complex and irregular canal systems that harbor bacteria and necrotic tissue. Sodium hypochlorite not only helps eliminate a broad spectrum of microorganisms but also dissolves organic debris, improving canal cleanliness and reducing the risk of post-treatment infection. When used in appropriate concentrations, it can significantly enhance the success of pulpectomy procedures in pediatric patients while maintaining safety.

Intervention group 3
SalineOTHER

Saline is commonly used as an irrigant in the root canal treatment of primary molars due to its excellent biocompatibility and safety profile. It is a non-toxic, isotonic solution that poses no risk to the surrounding periapical tissues, which is particularly important in primary teeth where root resorption and open apices are common. This minimizes the chance of damaging the underlying permanent tooth germ, a critical consideration in pediatric dentistry. Saline is also safe if accidentally extruded beyond the apex or ingested, making it a suitable choice for young children.
