Summary
Certain oral bacteria, including motile rods and Prevotella intermedia, are linked to gingivitis in pubertal children. These findings aid in identifying individuals at higher risk for worsening gum inflammation.
Area of Science:
- Microbiology
- Periodontology
- Pediatric Dentistry
Background:
- Gingivitis is common in adolescents, but the specific subgingival microflora associated with its progression remains incompletely understood.
- Understanding microbial differences between pubertal children and young adults can offer insights into age-related oral health changes.
Purpose of the Study:
- To investigate the subgingival microflora in pubertal children and young adults.
- To identify specific bacterial species correlated with gingivitis and bleeding on probing in adolescents.
- To explore microbial clustering for predicting high-risk individuals for severe gingivitis.
Main Methods:
- Subgingival plaque samples were analyzed using anaerobic culture and phase contrast microscopy.
- Gingival Index (GI) and bleeding on probing were assessed.
- Pubertal children were clustered based on microbial profiles.
Main Results:
- Motile rods, spirochetes, and Prevotella intermedia were proportionally elevated in pubertal children with gingivitis.
- These bacteria positively correlated with bleeding on probing and GI.
- Three distinct microbial clusters were identified; clusters 1 and 2 contained gingivitis subjects, with higher proportions of motile rods, P. intermedia, and Eikenella corrodens in cluster 2.
Conclusions:
- Motile rods, P. intermedia, and Eikenella corrodens are key indicators differentiating gingivitis severity in pubertal children.
- These microbial markers can potentially be used for screening high-risk individuals prone to severe gum inflammation.
