Effect of a Denture Adhesive on Saliva Secretion and Orofacial Sicca Symptoms
Objectives: To determine, whether a 3-week continuous use of denture adhesives (DAs) influences the unstimulated whole saliva (UWS), the palatal (PS) and labial saliva (LS) flow rates, and to investigate the possible changes in the subjective Orofacial Sicca Symptoms (OSS).
Methods: Twenty-eight elderly maxillary complete denture wearing patients (average age: 70 ± 10 years) were investigated. DA (Blend-a-Dent Extra Stark Neutral (Procter & Gamble, Hungary) was administered to the patients for regular daily use during the 3 weeks of the examination. A standardized questionnaire was used to evaluate subjective orofacial and extraoral sicca symptoms. UWS was determined by the spitting method, PS and LS flow rates were measured with filter paper discs, using the Periotron device at the initial, first, second and third weeks. The statistical analysis methods employed were the followings: subjective values - χ2-test; flow rates - ANOVA, paired Student's t-test.
Results: According to the questionnaire, the ratio or severity of xerostomia was not changed. A significant increase in the subjective feeling of “saliva thickness” (p=0.027), and a non-significant increase in the feeling of “insufficient amount of saliva” and of the nasal dryness could be detected, but other subjective parameters remained unchanged. Among salivary parameters, PS flow rates decreased significantly by week 3 (p=0.024), but there was no significant change in UWS and LS flow rates.
Conclusions: Regular use of DA did not influence the ratio or severity of xerostomia, but may cause a subjective feeling of “increased saliva thickness” and reduce palatal minor salivary gland flow rates among complete maxillary denture wearers.
