Objectives:
The aim of this study was to compare the impact of two different tooth replacement strategies on the nutritional status of partially dentate older patients. Nutritional status was measured using the full version of the Mini Nutritional Assessment (MNA) and the short form of the Mini Nutritional Assessment (MNA-SF).
Materials And Methods:
A randomised controlled clinical trial was conducted (Trial Registration no. ISRCTN26302774). Partially dentate patients aged 65 years and older were recruited and randomly allocated to the two different treatment groups: the removable partial dentures (RPD) group and the shortened dental arch (SDA) group. Nutritional status was measured using the MNA and MNA-SF administered at baseline and 1, 6 and 12 months after treatment intervention by a research nurse blinded to the treatment group allocation of all participants.
Results:
Data collected using the full version of the MNA showed significant improvements in mean MNA scores over the length of the study (p < 0.05). For the entire patient group, there was a mean increase of 0.15 points at 6 months and a further increase of 0.19 points at 12 months. These increases were similar within the treatment groups (p > 0.05). For MNA-SF, the analysis showed that there were no significant differences recorded over the data collection points after treatment intervention (p < 0.05).
Conclusion:
Tooth replacement using conventional and functionally orientated treatment for the partially dentate elderly showed significant improvements in MNA score 12 months after intervention.
Clinical Relevance:
Prosthodontic rehabilitation may play an important role in the nutritional status of partially dentate elders.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
