It is well documented that the selection of nutritional items is decisively influenced by the dental status. However, there is only little information whether this is also reflected in the individual nutritional status and consequently in typical nutritional-blood-markers.


Hence it was the aim of this clinical study to analyse potential correlations between the dental status and three nutritional-blood-markers in elderly patients. The following null hypothesis was tested: The dental status does not affect the blood-markers a) folate, b) albumin and c) cobalamin.

Material and Methods

In eighty patients (Department of Geriatrics, Bonifatius Hospital Lingen/Ems, Germany; minimum age 60 years) the following parameters were investigated: The blood-markers folate, albumin and cobalamin, the dental status (score 1: no treatment necessary to 4: treatment obligatory) and the Mini Nutritional Assessment® (MNA®, score 0: normal nutritional status, 1: at risk of malnutrition, 2: malnourished). Additionally a masticatory function test (comminution of a carrot slice, diameter 2cm and height 1cm, chewing time 45s, score 1: excellent comminution to 6: comminution impossible, Fig. 1) was carried out. For statistical analysis (SPSS 17.0) of normally distributed data Oneway Anova was used; otherwise a Kruskal-Wallis H-test was applied. Furthermore a Spearman regression for the dental status and the masticatory function test was calculated.

The mean score (Mean ± StD) for the dental status was 3.0 ± 0.8 and 0.8 ± 0.6 for the MNA® (Tab. 1). A significant correlation (Spearman, p < 0.05) between dental status and the masticatory function test (3.8 ± 1.6) (Fig. 2) as well as albumin could be observed. However, there was no correlation between dental status and the MNA®, folate (7.0 ± 3.7 ng/ml) or cobalamin (394.9 ± 270.9 pg/ml). Thus only part b of the null hypothesis could be rejected.

As multimorbidity and thus multimedication is typical for elderly people our data may be influenced otherwise. Though patients with known problems in their reported history concerning multimedication were excluded from the study, probably some were not aware of their medical status and did not fully report.
Since all folate and cobalamin mean values are within the normal range and all albumin mean values (except the dental status) are also within the normal range regardless of the dental status no general correlation between dental status and blood-markers could be identified.
