OBJECTIVES: Parkinson's disease (PD) affects oral health, but prevalence of subjective and objective halitosis and the influence of hyposalivation remain unclear. We aimed to explore whether patients with PD suffer from halitosis and to define correlations between halitosis and hyposalivation. We hypothesised that patients with PD suffer more often from halitosis compared to healthy controls, influenced by dry mouth. MATERIALS AND METHODS: Subjective (halitosis, xerostomia visual analogue scale [VAS], short German Oral Health Impact Profile [OHIPG]-14) and objective scales (e.g., organoleptic score, volatile sulphur compounds [VSCs], stimulated whole saliva [SWS]) were assessed from 26 patients with PD and 26 healthy controls. RESULTS: The mean organoleptic score was 0.7 (SD: 0.7) in all patients, and VSCs were either comparable or significantly lower (dimethyl sulphide, P = .010) in PD patients compared with controls, yet more patients with PD perceived halitosis to be stronger (77% vs 54%, respectively; P = .059). Dry mouth was significantly more likely in patients with PD than controls: mean xerostomia VAS 4 (SD: 2) vs 1 (SD: 2), P = .010; SWS 0.4 (SD: 0.4) vs 0.7 (SD: 0.6) mL/min, P < .05); SWS did not correlate with subjective or objective halitosis. Oral health-related quality of life (OHRQoL) was lower in patients with PD than controls (mean OHIPG-14 score 12 (SD: 0.2) vs 5 (SD: 7.0), respectively; P < .05). CONCLUSIONS: Patients with PD suffer from subjective and objective halitosis, dry mouth and impaired OHRQoL. Dry mouth problems do not correlate with prevalence or intensity of halitosis.
