Halitosis in periodontitis patients is linked to tongue coating and plaque, not directly to periodontal inflammation measures like PISA. Good oral hygiene appears crucial for managing bad breath in these individuals.
Area of Science:
- Oral Medicine
- Periodontology
- Halitosis Research
Background:
- Halitosis (oral malodour) is common in periodontitis patients, but the relationship requires further clarification.
- Understanding the factors contributing to halitosis in periodontitis is essential for effective management.
Purpose of the Study:
- To investigate the association between halitosis indicators, periodontitis clinical markers, tongue coating, and Periodontal Inflamed Surface Area (PISA).
Main Methods:
- Assessed halitosis using organoleptic scores and a portable sulphide monitor in 10 periodontitis patients.
- Conducted comprehensive periodontal exams, measuring probing depth, recession, attachment level, bleeding on probing, plaque, and tongue coating.
- Calculated Periodontal Inflamed Surface Area (PISA) based on clinical attachment level, gingival recession, and bleeding on probing.
Main Results:
- Organoleptic scores correlated significantly with tongue coating (r=0.554) and plaque (r=0.614).
- No correlation was found between halitosis measures and probing depth or PISA.
- A strong correlation existed between organoleptic scores and volatile sulphur compounds (r=0.931).
Conclusions:
- Halitosis in periodontitis is multifactorial, involving a complex interplay of factors.
- Tongue coating and oral hygiene practices appear to play a significant role in halitosis development in periodontitis patients.
