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.
The aim of this study was to examine the prevalence and relationship between periodontal disease and preterm low birth weight (PLBW) among Saudi mothers at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia. The periodontal status and the relative risk were also analyzed. The study consisted of 30 cases [infants <37 weeks and/or weighing ≥2.500 kilograms (kg)] and a daily random sample of 60 controls [≥ 37 weeks and/or weighing >2.500 kg]. Clinical periodontal indices were measured on the labor wards. Associated risk factors for periodontal disease and PLBW were ascertained by means of a structured questionnaire and maternal notes. The prevalence of the PLBW was found to be 11.3%, and the prevalence of periodontal disease was high among the study population. The risk of PLBW remained high with increasing periodontal disease (odds ratio [OR] 4.21, 95% confident interval [CI] 1.99-8.93) despite controlling the other risk factors such as age, smoking, and social class. In conclusion, there is a correlation between periodontal disease and PLBW in KKUH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
