Deterioration of Resilient Denture Liners and Patient Characteristics

NCT02587676 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 100

No results posted yet for this study

Summary

Thirty complete maxillary denture wearers were recruited after obtaining informed consent. One investigator measured the Shore D hardness of the commercially available RDLs using a Vesmeter®. The salivary flow rates and pH values and the occlusal force were measured for all patients before initiation of the study.

T-tests and Pearson's correlation coefficients were used for statistical analyses.

A p-value of \<0.05 was considered statistically significant.

The deterioration of RDLs may differ between in vitro conditions and the conditions encountered in denture wearers. We conducted an in vivo study to investigate how resilient denture liners (RDLs) changed in hardness when embedded in complete maxillary dentures worn by patients for one month in a clinical setting. We hypothesized that the hardness one month after application of the RDLs would be affected by the age, the condition of the saliva, the occlusal force, type of denture used, the patients habits related to smoking, drinking, wearing dentures while sleeping, and using a denture cleanser.
