Prevalence and Factors Associated with the Use of Denture Adhesives by Older Complete Denture Wearers

This study investigated the prevalence and the factors affecting the use of denture adhesives (DA) by older complete denture wearers. One hundred patients were interviewed and clinically examined for dentures' retention, stability and occlusion. A total of 31% used DA on a regular basis or sometimes; 14% used DA on both dentures, 19% on the maxillary denture and 26% on the mandibular one. DA use on the maxillary denture was significantly associated with younger age (p=0.026) and lower frequency of dentures' use (p⟨0.005), while their use on the mandibular denture was associated with the lower frequency of dentures' use (p⟨0.05) and good retention and stability of the maxillary denture (p=0.007). Multiple logistic regression analyses revealed that the DA use on maxillary dentures was significantly associated with younger age (odds ratio=0.938, p=0.026), while their use on the mandibular one was associated with good retention and stability of maxillary denture (odds ratio=1.451, p=0.007). These findings suggested that patient-driven factors, such as patients' age and denture's use habits had more significant effect on DA use than the denture's technical characteristics. Those factors should be further investigated to guide dentists in personalised recommendations on DA use to improve denture patients' quality of life.
