Abstract

Abstract: Background: Tobacco smoking compromises the prognosis of dental implant treatment and is associated with increased risk of peri‐implant bone loss and increased implant failure rate. There is a dearth of studies that have compared clinical, radiographic, and immunological peri‐implant parameters among cigarette smokers (CS), individuals vaping e‐cigarettes (e‐cigs), and non‐smokers (NS). This study aimed to compare clinical and radiographic peri‐implant parameters and levels of matrix metalloproteinase (MMP)‐9 and interleukin (IL)‐1β levels among CS, individuals' vaping e‐cigs, and NS. Methods: Thirty‐two CS (group 1), 31 individuals vaping e‐cigs (group 2), and 32 NS (group 3) 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 marginal bone loss (MBL) were assessed using standardized digital radiographs. Enzyme‐linked immunosorbent assay was used to assess levels of MMP‐9 and IL‐1β in peri‐implant sulcular fluid. Pearson correlation coefficient was used to analyze for correlations of MMP‐9 and IL‐1β levels with peri‐implant parameters. Results: BOP showed significantly higher values in group 3 as compared with groups 1 and 2 ( P < 0.01). PI ( P < 0.01), PD ≥ 4 mm ( P < 0.01), and mean concentrations of MMP‐9 ( P < 0.001) and IL‐1β ( P < 0.01) were significantly higher in groups 1 and 2 than group 3. MBL was significantly higher in group 1 as compared with group 2 and group 3 ( P < 0.01). Significant positive correlations were found between MMP‐9 ( P = 0.0198) and IL‐1β ( P = 0.0047) levels and MBL in group 1; and a significant positive correlation between IL‐1β and MBL in group 2 ( P = 0.0031). Conclusions: Peri‐implant health was compromised among CS than vaping individuals and NS. Increased levels of proinflammatory cytokines in CS and vaping individuals may suggest greater peri‐implant inflammatory response.
