Association between root caries occurrence and periodontal state

Area of Science:

• Dentistry
• Periodontology
• Cariology

Background:

• Root caries is a significant oral health concern, particularly in adults.
• The relationship between periodontal disease and root caries requires further investigation.

Purpose of the Study:

• To investigate the association between periodontal status and the prevalence of root caries in Finnish adults.
• To identify specific periodontal factors linked to increased root caries risk.

Main Methods:

• Clinical examination of a representative sample of 4,777 Finnish adults aged 30 and older.
• Assessment of root caries, gingival inflammation, periodontal pockets, and subgingival calculus.
• Statistical analysis to determine correlations between periodontal health and root caries.

Main Results:

• Only 4% of subjects with healthy periodontium had root caries.
• Prevalence increased to 15% with gingival inflammation and 17% with deepened periodontal pockets.
• Deeper pockets correlated with higher root caries frequency in men; subgingival plaque retention showed a strong association.

Conclusions:

• Periodontal health is a critical factor in root caries development.
• Adults with signs of periodontal disease, particularly men, face a higher risk of root caries.
• Effective plaque control is essential for preventing root caries in compromised periodontal states.
