Summary
This summary is machine-generated.

Using size 08 K-Flex files or size 10 reamers for apical patency in root canals resulted in minimal transportation. However, XF finger spreaders significantly increased root canal transportation at the major foramen.

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Maintaining apical patency is crucial during root canal treatment.
  • The choice of instrument for patency can influence root canal anatomy, specifically apical transportation.

Purpose of the Study:

  • To compare root canal transportation at the major foramen using size 08 K-Flex files, size 10 reamers, and XF finger spreaders as patency instruments.

Main Methods:

  • 102 mesiobuccal canals were divided into three groups, each using a different patency instrument.
  • Pre- and post-instrumentation images of the major foramen were analyzed using Photoshop to quantify apical transportation.
  • Chi-squared test was used for statistical analysis.

Main Results:

  • Overall, 22% of specimens showed transportation.
  • Group A (size 08 K-Flex files) had 9% transportation.
  • Group B (size 10 reamers) had 12% transportation.
  • Group C (XF finger spreaders) showed significantly higher transportation at 44%.

Conclusions:

  • Size 08 K-Flex files and size 10 stainless steel reamers demonstrated minimal root canal transportation when used for apical patency.
  • XF finger spreaders, when employed for maintaining apical patency, led to the most significant transportation of the major foramen.
