Root canal treatment in necrotic primary molars

Area of Science:

• Pediatric Dentistry
• Endodontics
• Dental Materials

Background:

• Necrotic primary teeth pose treatment challenges in children.
• Effective root canal treatment is crucial for maintaining primary dentition.
• Limited studies evaluate specific paste formulations for pediatric endodontic success.

Purpose of the Study:

• To evaluate the clinical and radiographic success of KRI-1 paste combined with calcium hydroxide and formocresol.
• To assess the long-term outcomes of this specific root canal filling material in primary teeth.
• To provide evidence for an effective treatment option for necrotic primary teeth.

Main Methods:

• Fifty-three children with necrotic primary teeth underwent root canal treatment.
• A KRI-1 paste formulation with calcium hydroxide and formocresol was used as the root canal filling.
• Patients were followed clinically and radiographically for 6 to 24 months, with some histological assessment.

Main Results:

• All treated cases showed clinical success.
• Radiographic evaluations confirmed successful outcomes in all patients.
• Histological data, where available, supported the clinical and radiographic findings.

Conclusions:

• The KRI-1 paste formulation with calcium hydroxide and formocresol is a clinically and radiographically successful treatment for necrotic primary teeth.
• This endodontic approach offers a viable solution for managing infected primary teeth in pediatric patients.
• Further research can explore long-term histological integration and tissue response.
