Comparison Of Tooth Replacement Strategies On The Nutritional Status Of Older Patients: A Randomised Controlled Clinical Trial



Diet plays a key role in disease prevention in older age. Although nutritional state is influenced by various factors, dental status can have an important impact.  Poor oral health and loss of teeth can have significant negative effects on dietary intake and nutritional status for older patients. Increasingly, patients are retaining some natural teeth into old age (partially dentate). Many receive removable partial dentures to replace all missing teeth despite their potential to increase the risk of further dental disease. Alternative, functionally-orientated treatments exist including the shortened dental arch (SDA).  Instead of aiming to replace all missing teeth, this provides patients with 10 pairs of teeth which are easy to maintain whilst ensuring acceptable function and aesthetics.  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. The study compared conventional treatment using removable partial dentures and functionally-orientated treatment based on the SDA.



50 partially dentate patients (mean age 68.8 years) completed a randomised controlled clinical trial. 26 patients were allocated to conventional treatment with removable partial dentures and 24 were allocated to functionally-orientated treatment with adhesive bridgework used to create 10 pairs of teeth. Nutritional status was assessed at baseline and 1 month after treatment using a range of haematological markers and the Mini Nutritional Assessment (MNA).



1 month after treatment intervention, haematological measures did not illustrate a clear picture of improvement for either group. For the conventional group average levels of vitamin B12 (p=0.68), albumin (p=0.20) and cholesterol (p=0.50) all increased. For the functionally-orientated group average levels of vitamin B12 (p=0.62), albumin (p=0.16) and vitamin D (p=0.37) all increased. MNA scores improved for both treatment groups post operatively. For the conventional group mean MNA score increased from 23.3 to 24.4 (p=0.03). For the functionally-orientated group mean MNA score increased from 23.2 to 24.1 (p=0.03).  



Haematological markers did not demonstrate any statistically significant improvements in nutritional status for either treatment group. However, MNA scores improved for both conventional and functionally-orientated groups after treatment intervention (p=0.03).
