Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study

Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests a 6-month nutritional program for adults aged 60–80 who wear complete dentures. Participants receive personalized dietary advice, meal plans, cooking workshops, and a mobile app. The goal is to see if the program improves diet quality, chewing ability, muscle strength, cognitive performance, and quality of life compared to usual eating habits.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Nutritional intervention (dietary counseling, meal plans, cooking workshops, mobile app)
What this could lead to
If effective, this dietary program could help older denture-wearers eat better, maintain muscle strength, and stay mentally sharp.
What could go wrong
This is a small early-stage study with only 40 participants, so results may not apply broadly. The intervention requires significant commitment and may not work for everyone.

Inclusion Criteria: * Men and women aged 60 to 80 years. * Systemically healthy individuals or those with controlled chronic systemic conditions under regular medical supervision. * Functionally independent individuals, or those with a dedicated family member or caregiver available to provide support throughout the study period. * Wearers of both maxillary and mandibular complete removable dentures. * Adequate stability, retention, and functionality of both complete dentures allowing the participant to chew effectively during daily meals (accepting minor retention or stability limitations in the mandibular prosthesis, provided routine functional mastication is maintained). * Acceptable centric occlusion and jaw relationship allowing functional mastication. * Intact oral mucosa without active lesions or severe soreness in the denture-bearing areas. Exclusion Criteria: * Altered salivary flow (hyposalivation or xerostomia) identified via anamnesis and sialometry, with an unstimulated salivary flow rate \< 0.1 mL/min or a stimulated salivary flow rate \< 0.5 mL/min. * Active oral mucosa diseases or lesions (e.g., cheilitis, denture stomatitis, ulcers, or aphthae) verified through intraoral examination. * Diagnosis of a major neurocognitive disorder by a qualified professional, verified via medical records and/or caregiver interview. * Color blindness (daltonism or color vision deficiency). * Presence of signs or symptoms of temporomandibular disorders (TMD). * Known history of allergy to peanuts or latex. * Underweight or severe undernutrition, defined as a Body Mass Index (BMI) \< 18.5 kg/m².
