Objective: The aim of the present observational case-control study was to compare the levels of Receptor activator of NF-kappa B ligand (RANKL) and osteoprotegerin (OPG) in the gingival crevicular fluid (GCF) of cigarette- and waterpipe-smokers and electronic-nicotine-delivery-systems (ENDS)-users.

Methods: Demographic data was collected using a questionnaire. Clinical periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD] and clinical attachment loss [CAL]) were measured; and GCF samples were collected from the deepest periodontal pocket of the mandibular right first molar.
