Summary
Microbial analysis of root canals in chronic diffuse periapical lesions revealed heavy bacterial infection. Cocci were the most prevalent morphotype, followed by bacilli, coccobacilli, fungi, and spirochetes.
Area of Science:
- Microbiology
- Endodontics
- Oral Pathology
Background:
- Chronic diffuse periapical lesions often indicate persistent root canal infection.
- Understanding the microbial composition is crucial for effective endodontic treatment outcomes.
Purpose of the Study:
- To identify and quantify various microbial morphotypes present in root canal infections associated with chronic diffuse periapical lesions.
Main Methods:
- Specimens were collected from root canals of 40 asymptomatic teeth with diagnosed periapical lesions.
- Samples underwent fixation and examination using four distinct staining methods under microscopy.
Main Results:
- All examined root canal specimens showed heavy bacterial infection.
- Cocci were the most frequent (92%), including Gram-positive diplococci and cocci in clusters.
- Bacilli (67%), coccobacilli (37%), fungi (17%), and spirochetes (5%) were also identified.
Conclusions:
- Root canal infections in chronic diffuse periapical lesions harbor a diverse microbial community, predominantly cocci.
- The findings highlight the polymicrobial nature of these infections, guiding therapeutic strategies.
