Effect of Smoking on Saliva Composition and the Development of Dental Erosion
Study Details
Study Description
Brief Summary
The aim of this study is to investigate whether smoking is associated with changes in salivary composition and/or predisposition to erosion.
Healthy volunteers are observationally wearing an intraoral device with both bovine tooth specimens (enamel and dentin) and resin specimens twice for two hours each. Afterwards, specimens are eroded extraorally and calcium release into the acid is measured.
Total protein concentration and protein composition of the salivary pellicles on the resin samples are measured. Additionally, salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity, and total protein content as well as concentration of inorganic calcium, phosphate, and fluoride) are measured.

Outcome Measures
Primary Outcome Measures
- Calcium release from bovine enamel and dentin specimens by extraoral erosion (nmol/Square Millimeter). [Immediately after the intraoral device has been worn once for two hours.]
Secondary Outcome Measures
- Determination of unstimulated and stimulated saliva flow rate (mL/min). [Saliva samples are collected for 5 min each on three visits.]
- Determination of saliva pH (pH). [Saliva samples are collected for 5 min each on three visits.]
- Determination of salivary buffer capacity (pH). [Saliva samples are collected for 5 min each on three visits.]
- Determination of total protein content (mg/L) in saliva. [Saliva samples are collected for 5 min each on three visits.]
- Determination of inorganic calcium (mmol/l), phosphate (mmol/L) and fluoride (µmol/L) in saliva. [Saliva samples are collected for 5 min each on three visits.]
- Determination of total protein concentration (ng/Square Millimeter) and protein composition (qualitatively) within the salivary pellicles. [Immediately after the intraoral device with resin samples has been worn once for two hours.]
