Introduction : oral health is a prerequisite for a good chewing function, which may have an impact on food choices and nutritional well-being. Thus this study was carried out to evaluate the association between oral health and the nutritional studies of elderly patients with diabetes in the Yaounde Central Hospital. Methods : we carried out a cross-sectional descriptive and analytical study at the National Obesity Centre of the Yaounde Central hospital. We included consecutively 90 elderly patients with diabetes (60 years and above). We assessed their oral health by carrying out a complete oral examination and a subjective oral health assessment of the participants was also carried out. We then assessed the nutritional status of participants using anthropometric parameters, Mini nutritional assessment (MNA) and fasting serum albumin concentrations. Results : ninety participants (60 females and 30 males) aged 66.9 ± 6.1 years were included in our study. With 37% of our participants haven been known diabetic for more than 10 years. Severe and moderate periodontitis was observed in 56(62.2%) and 29(32.2%) of our participants respectively. At least a decay tooth was present in the mouth of 70(77.8%) of our participants. Half 45((50.0%) of our participants declared to be unsatisfied with their oral health, 52(57.8%) limit their food choice because of their oral health. Using the percentage total body fat, 19(63.3%) men and 11(36.7%) women were underweight. The mean BMI of the study population was 27.6 ± 5.26. Seventeen (18.9%) of our participants were malnourished, 70(77.8%) at risk of malnutrition. Mean serum albumin concentration was 29.4 ± 2.2g/l. There was a statistical significance between CPI severity and serum albumin levels of our participants (P value = 0.02) and also between remaining natural teeth and MNA score (P value = 0.001). Conclusion : oral health problems were frequent in our study population, all our participants had moderate to severe periodontitis with some to the extent of edentulism. We found a strong relation between the severity of periodontitis, number of remaining natural teeth and the nutritional status of our study participants.
