Summary

Certain bacterial species, like Actinomyces viscosus or mutans streptococci and Lactobacillus, drive root surface caries progression. Dominance of single acidogenic species correlates with high mineral loss in dental caries.

Area of Science:

  • Oral microbiology
  • Dental caries research
  • Periodontology

Background:

  • Root surface caries is a significant oral health concern, particularly in elderly individuals.
  • Understanding the microbial composition of active root caries lesions is crucial for developing targeted prevention and treatment strategies.

Purpose of the Study:

  • To characterize the microflora associated with actively progressing root surface caries lesions.
  • To correlate specific bacterial species with the degree of mineral loss in experimental caries.

Main Methods:

  • Experimental induction of root surface caries in human molar specimens worn by elderly individuals.
  • Collection of plaque and dentin samples using a punch technique.
  • Identification of 780 bacterial isolates from 13 plaque and 6 dentin samples.

Main Results:

  • Distinct individual differences in microflora composition were observed.
  • High mineral loss lesions were dominated by Actinomyces viscosus or a combination of mutans streptococci and Lactobacillus species.
  • Lesions with less mineral loss showed a more complex microflora with variations in Actinomyces, mutans streptococci, and Veillonella species.

Conclusions:

  • Specific bacterial species or combinations are more cariogenic, contributing to root surface caries.
  • Dominance of single acidogenic species is strongly associated with high caries activity and mineral loss.
