A smart rotary technique versus conventional pulpectomy for primary teeth: A randomized controlled clinical study

Area of Science:

• Pediatric Dentistry
• Endodontics

Background:

• Accurate working length determination and reduced treatment time are crucial for pulpectomy in pediatric dentistry.
• The study addresses the need for efficient and precise endodontic procedures in primary teeth.

Purpose of the Study:

• To evaluate the accuracy of the Root ZX II electronic apex locator for root canal length measurement.
• To assess the efficiency of a rotary system in pulpectomy of primary teeth.
• To compare these methods with conventional techniques.

Main Methods:

• A randomized controlled clinical trial involving 80 primary molars in children aged 4-6 years.
• Pulpectomy performed using either conventional methods or the Root ZX II apex locator with Mtwo rotary files.
• Statistical analysis using Mann-Whitney and Chi-Square tests.

Main Results:

• No significant difference in the accuracy of root canal length determination between the electronic apex locator and conventional methods.
• Significantly shorter instrumentation time was observed when using the rotary system (P=0.000).

Conclusions:

• The Root ZX II apex locator and rotary system provide comparable accuracy to conventional methods for pulpectomy in primary teeth.
• The combined approach offers a considerable reduction in instrumentation time.
• This technique is a viable and potentially advantageous option for pulpectomy in primary molar teeth.
