Impact of Different Prosthodontic Treatment Modalities on Nutritional Parameters of Elderly Patients

Abstract

Purpose: To assess dietary and nutritional changes among the elderly following pros-thodontic rehabilitation. Another objective was to study the relationship, if any, between diet and nutrition, with extent of edentulism and different types of prosthodontic treatment.

Materials and methods: One hundred and thirty-five patients who satisfied the inclu-sion and exclusion criteria and agreed to be a part of the study after informed consent were recruited to this longitudinal study. Following selection, they were investigated on four aspects: dental examination, dietary assessment, anthropometric assessment, and serum biochemical assessment. All measurements were collected twice, first at baseline and then 6 months following prosthodontic rehabilitation. Treatment modalities included were complete denture (CD), removable partial denture (RPD), and fixed partial denture (FPD). The RPD group was of two types: distal extension prosthesis (RPDD) and tooth-supported prosthesis (RPDT). Change (post-pre) in outcome measures was compared by one-way ANOVA, and significance of mean difference between the groups was done by Tukey's honestly significance difference post hoc test.

Results: The improvement in diet was found to be: CD > RPDD > RPDT > FPD. Significant improvement in weight (p < 0.001), BMI (p < 0.001), protein (p < 0.001), carbohydrate (p = 0.021), calorie (p < 0.001), iron (p = 0.002), and vitamin B (p < 0.001) in group CD as compared to partially edentulous patients (group RPDD + RPDT + FPD) was noted. The protein and calorie intake increased significantly in group RPD as compared to group FPD in partially edentulous patients.

Conclusion: Prosthetic rehabilitation becomes increasingly important as the level of edentulism increases to improve dietary, anthropometric, and biochemical parameters.
