RESUMO
AIM: The monocyte-to-high-density lipoprotein cholesterol ratio (MHR) has currently been proposed as an indicator of inflammation. The aim of the present study was to assess the relationship between the monocyte-to-high-density lipoprotein cholesterol ratio and periodontal health and disease. MATERIALS AND METHODS: A total of 90 patients were selected for the study - 30 healthy patients (group I) and 60 periodontitis patients (groups II and III). All the patients were subjected to blood sampling and serum malondialdehyde (MDA), high-density lipoprotein cholesterol (HDL) levels and monocyte counts were estimated. RESULTS: Monocyte-to-high-density lipoprotein cholesterol ratio was 80.64 ± 28.71 for patients with moderate periodontitis (group II), 95.14 ± 53.21 in severe periodontitis (group III), and 14.28 ± 16.05 for the healthy patients. Monocyte-to-high-density lipoprotein cholesterol ratio values were found to be statistically significantly higher than the control group (p < 0.001). Monocyte-to-high-density lipoprotein cholesterol ratio also showed significantly positive correlation with the severity of periodontitis. CONCLUSION: Malondialdehyde and MHR are increased in periodontal disease and correlate with severity of the periodontal disease. CLINICAL SIGNIFICANCE: Monocyte-to-high-density lipoprotein cholesterol ratio is a novel, readily available inflammatory and oxidative stress marker in patients with periodontitis and can be useful to evaluate periodontitis and disease severity.
