Abstract

Abstract: Introduction and aim: To determine whether the continuous use of gel-type denture adhesives influence the unstimulated whole saliva, the palatal and labial saliva flow rates, and to assess the possible changes of subjective orofacial sicca symptoms. Method: 28 maxillary complete denture wearing patients (average age: 70 ± 10 years) were investigated. A gel-type denture adhesive was administered to the patients for regular use during the 3 weeks of examination. A questionnaire of 16 questions was used to evaluate subjective orofacial sicca symptoms. Unstimulated whole saliva was determined by the spitting method, palatal and labial saliva flow rates were measured by the Periotron® device with filter paper discs at the initial, first, second and third weeks. Statistical analysis: The following tests were used: subjective values – χ2-test; flow rates – ANOVA, paired Student’s t-test. Results: According to the questionnaire, the ratio or severity of xerostomia did not change. A significant increase in the subjective feeling of “saliva thickness” could be detected (p = 0.027), but the other subjective parameters remained unchanged. Palatal saliva flow rates decreased significantly by week 3 (week 0: 4.21 ± 3.96 µl/cm2/min; week 3: 2.21 ± 2.30 µl/cm2/min; p = 0.024). On the other hand, there was no significant change in the unstimulated whole saliva (week 0: 0.37 ± 0.36 ml/min; week 3: 0.39 ± 0.35 ml/min) and labial saliva (week 0: 3.99 ± 3.75 µl/cm2/min; week 3: 2.58 ± 3.39 µl/cm2/min) flow rates. Conclusions: The regular use of denture adhesives did not influence xerostomia and the majority of subjective orofacial sicca symptoms, but may cause a subjective feeling of “increased saliva thickness” and reduce palatal minor salivary gland flow rates among complete maxillary denture wearers.
