sRANKL and its correlation with metabolic syndrome parameters in children

摘要

Background Activating receptor ligand for nuclear factor (RANKL) has been identified as a ligand attached to the cell membrane of osteoblasts and odontoclasts. Aim To determine a possible association of sRANKL in saliva and serum with the parameters of metabolic syndrome (MS) in paediatric population aged 8‐12?years. Design This was a clinical, analytical and comparative study. Students between 6 and 12?years with good oral hygiene were included. Anthropometry, clinical analysis, dentobacterial plaque registration were registered as well as sRANKL in total saliva and serum through the ELISA technique. Results A total of 43 children were enrolled, with a mean age of 9.7 (±0.8?years). Contrasting the groups by the presence or absence of the waist circumference above the normal limit, the difference in serum sRANKL concentration was statistically significant ( P? ≤ ? 0.05). A negative statistical significance was found in the correlation between serum sRANKL and HDLc ( r 2 ?=??0.310, P?=? 0.046). Saliva sRANKL did not show statistical difference between neither gender nor body mass index and was not correlated with any parameter of the MS. Conclusions A good oral hygiene seems to avoid the effects of MS on the oral cavity.
