Oral Malodour and Periodontal Disease-related Parameters
|Study Design:||Observational Model: Case Control
Time Perspective: Cross-Sectional
|Official Title:||Oral Malodour and Periodontal Disease-related Parameters. Clinical and Real-time PCR Findings|
- Halitosis presence [ Time Frame: At a single time point ] [ Designated as safety issue: No ]Subjects were designated as halitosis positive (+) when either the organoleptic score of the whole mouth air was two or more, and/or the readings of the Halimeter® exceeded 140 p.p.b.
- Tongue coating [ Time Frame: At a single time point ] [ Designated as safety issue: No ]
Assessment of tongue coating:
The Winkel Tongue Coating Index (Winkel et al., 2003) was visually determined by dividing the dorsum of the tongue into sextants. A score between zero and two was given to each sextant according to the amount of deposits and these scores were added giving a total ranging from zero to 12.
- Putative periodontal pathogens [ Time Frame: At a single time point ] [ Designated as safety issue: No ]A specimen was collected from the rear of the tongue dorsum for quantitative analysis of two putative periodontal pathogens, P. gingivalis and F. nucleatum, by real-time PCR.
- Periodontal clinical indices [ Time Frame: At a single time point ] [ Designated as safety issue: No ]plaque index, clinical probing depth, clinical attachment levels and bleeding on probing.

Chronic periodontitis patients
Chronic periodontitis patients had at least one site per quadrant with clinical probing depth (CPD) > 5mm and radiographic evidence of bone loss
Generalised chronic gingivitis patients
Generalised chronic gingivitis patients presented with bleeding on probing (BOP) at > 30% of sites, CPDs < 4mm and no evidence of bone loss
Periodontally healthy subjects
Healthy subjects had < 10% sites with BOP and no sites with CPD > 3mm
