Background : Salivation is considered to be an important factor in the control of halitosis, and the amount of salivation has been shown to be closely related to the level of hydration. The purpose of our study was to evaluate the relationship between dehydration and halitosis.
Methods : Twenty healthy young women with no dental problem were recruited. All participants were asked to dehydrate and then over-hydrated. After inducing each hydration, the severity of hydration and halitosis factor(organoleptic scores, amounts of resting and functional saliva, gas examinations, tongue coatings) were measured. Hydration statuses were graded as dehydration, normal, or over-hydration according to urine osmolality. Cross sectional study with a cross over design was used.
Results : A dehydrated status was associated with the higher organoleptic scores than a normal or over-hydrated status(1.75±0.75 vs. 0.87±0.63 and 0.65±0.53, respectively, P <0.05). Mean values of CH3SH, (CH3)2S in gas chromatography for a dehydrated, normal, and over-hydrated status were 11.70±37.00, 6.75±13.50, 2.80±5.87 and 10.50±15.59, 7.25±10.87, 1.50±2.55 ppbv respectively, p>0.05). (CH3)2S(r =0.382, p=0.066) showed moderate correlations with dehydration status. The resting salivation rates were relatively lower for a dehydrated status than for a normal or over-hydrated status(p>0.05), and tongue coating results were also higher for a dehydrated status(p>0.05).
Conclusions : Dehydration status appears to be positively correlated with a low resting salivation rate, high gas chromatography results. This shows that dehydration might be an etiologic factor of halitosis.
