Design outcomes

Primary

Measure	Time frame
This study compares the changes in serum albumin value from baseline between the group where patients receive a dietary advice after new denture delivery (Group A) and the group where parients receive a dietary advice (Group B).	—

Secondary

Measure	Time frame
(1) Evaluation of nutritional status a. Blood tests: prealbumin, serum total protein, cholinesterase, total cholesterol, zinc, serum calcium, folic acid, retinol binding protein, transferrin, HDL/LDL cholesterol, white blood cell count, white blood cell picture, total peripheral blood lymphocyte count, hemoglobin level, serum vitamin C, amino acid analysis, C-reactive protein b. Body mass index (BMI) c. Assessment of dietary intake: Evaluation using Brief-type Self-administered Diet History Questionnaire (BDHQ) (2) Assessment of living environment: Evaluation using self-administered questionnaire (3) Subjective evaluation of denture quality (patient, dentist): Esthetic and stability evaluation using Visual Analog Scale (VAS) (4) Evaluation of oral-related quality of life: Evaluation using Oral Health Impact Profile (OHIP) (5) Evaluation of masticatory function: glucose elution from gummy jelly chewing, occlusal force, occlusal contact area	—
