Effect of denture adhesives on masticatory performance: Multicenter randomized controlled trial

Area of Science:

• Dentistry
• Biomaterials Science
• Clinical Trials

Background:

• Complete denture wearers often experience reduced masticatory performance.
• Denture adhesives are commonly used to improve denture stability and function.

Purpose of the Study:

• To evaluate the efficacy of powder and cream denture adhesives on masticatory performance in complete denture wearers.
• To compare the effects of denture adhesives against a saline control group.

Main Methods:

• A 10-center, parallel, randomized controlled trial involving complete denture wearers in Japan.
• Participants were randomized into powder-type adhesive, cream-type adhesive, or saline (control) groups.
• Masticatory performance was assessed using color-changeable chewing gum.

Main Results:

• All groups demonstrated significant improvements in masticatory performance post-intervention.
• No statistically significant differences in masticatory performance were found among the three groups.
• A negative correlation existed between changes in masticatory performance and intraoral condition scores.

Conclusions:

• Denture adhesives and saline yielded comparable improvements in masticatory performance for complete denture wearers.
• Denture adhesives may offer greater benefits for individuals with less favorable intraoral conditions.
