Peri-implant parameters, tumor necrosis factor-alpha, and interleukin-1 beta levels in vaping individuals

BackgroundTo the author's knowledge, there has been no study that has assessed clinical, radiographic, and immunological peri-implant parameters among individuals vaping e-cigarette (e-cig). PurposeThis pilot study aimed to compare clinical and radiographic peri-implant parameters and levels of tumor necrosis factor alpha (TNF-) and interleukin (IL)-1 levels among individuals vaping e-cigs and never smoker (NS). Materials and MethodsForty-seven individuals vaping e-cigs (group-1) and 45 NS (group-2) were included. Demographic and implant-related data were collected using a structured baseline questionnaire. Peri-implant plaque index (PI), bleeding on probing (BOP), and probing depth (PD) were recorded and peri-implant bone loss (PIBL) were assessed using standardized digital radiographs. Enzyme-linked immunosorbent assay was used to assess the levels of TNF- and IL-1 in peri-implant sulcular fluid. ResultsBleeding on probing showed statistically significantly higher values in group-2 patients as compared to group-1 patients (P<.01). Probing depth4 mm and PIBL was statistically significantly higher in group-1 patients as compared to group-2 patients (P<.05). Mean concentrations of TNF- (P<.001) and IL-1 (P<.01) were statistically significantly increased in individuals in group 1 as compared with group 2. A significant positive correlations were found between TNF- levels and BOP (P=.024) and PIBL (P=.016); and significant positive correlation was found between IL-1 and PIBL (P=.018) in group 1, respectively. ConclusionsClinical and radiographic peri-implant parameters are compromised among vaping individuals. Increased levels of proinflammatory cytokines in peri-implant sulcular fluid may suggest greater local inflammatory response in vaping individuals for peri-implant inflammation.
