A randomized controlled trial of changes in nutritional status of edentulous patients by prosthodontic treatment and dietary counseling

A study of changes in the nutrition status of patients with complete dentures by denture replacement and dietary advice

47

The selection criteria for study participants included edentulous individuals with maxillary, mandibular, or both maxillary and mandibular edentulism who were receiving treatment at the Department of Prosthodontics or the Department of Oral Function Management at Showa University Dental Hospital. Participants were required to possess functional dentures and provide written informed consent. The mean age of the participants was 73.4 +- 10.6 years, and a total of 39 individuals (17 males and 22 females) were included in the study.

Informed consent was obtained from 47 participants, who were then randomly assigned to Group A (n = 25) and Group B (n = 22). Among them, eight participants discontinued the study, and data from the remaining 39 participants were included in the final analysis.

No

After treatment, both groups exhibited a significant increase in occlusal force; however, no improvement in albumin levels was observed. Dietary assessment using the BDHQ indicated a significant post-treatment increase in seafood consumption in Group B. Furthermore, compared to Group A, Group B demonstrated a significant improvement in "methionine," "lysine," and "total essential amino acid" levels, as assessed by blood amino acid analysis, as well as a significant increase in seafood intake.

Prosthetic treatment was shown to improve masticatory function. Furthermore, the combination of prosthetic rehabilitation with dietary guidance likely contributed to an increase in dietary diversity, particularly in seafood consumption, which may have led to greater changes in blood amino acid concentrations.

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).

(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
