Microbiological root canal sampling (MRS) adoption by dentists showed slow but steady growth over 25 years. While most practitioners used MRS selectively, they generally produced valid samples for diagnosing root canal infections.

Area of Science:

  • Oral microbiology
  • Dental public health
  • Health technology diffusion

Background:

  • The adoption of new diagnostic technologies in dentistry is crucial for improving patient care.
  • Microbiological root canal sampling (MRS) offers a method for diagnosing endodontic infections.
  • Understanding the diffusion patterns of MRS among general dental practitioners is important for assessing its integration into routine practice.

Purpose of the Study:

  • To analyze the 25-year diffusion of microbiological root canal sampling (MRS) among general dental practitioners in Gothenburg.
  • To categorize the adoption levels of MRS and assess its diagnostic accuracy.

Main Methods:

  • Longitudinal study observing MRS adoption from 1966 to 1991 using laboratory records.
  • Categorization of adopters into 'occasional', 'selective', and 'regular' based on sample frequency.

  • Diagnostic accuracy assessment through culturing of 574 referred root canal samples from 1986.

    • Main Results:

    • MRS acceptance rate ranged from 2.9% to 5.1%, with a peak of 10.1% in 1986.
    • A minority of practitioners adopted MRS as a standard procedure; most used it selectively for specific cases.
    • Culturing results showed a predominance of facultative bacteria, with practitioners generally obtaining valid microbiological samples despite some contamination.

    Conclusions:

    • The diffusion of MRS in general dental practice has been gradual, with selective use being the predominant pattern.
    • Despite challenges with contamination, general dental practitioners were largely capable of producing valid microbiological samples for root canal infections.
    • Further strategies may be needed to encourage wider adoption and standardization of MRS in endodontic diagnosis.
