The goal of this study is to evaluate bone wound healing following extraction and alveolar ridge preservation (bone graft and membrane) clinically, histologically and in relation to gene expression in smokers and non-smokers. Data from a small group of participants will be analyzed after age-matched subjects undergo extraction and alveolar ridge preservation prior to implant placement. The data obtained in this pilot study will be used to plan a full-fledged study involving a larger number of smoking and non-smoking participants to compare the two groups.
Adult patients (18-75 years)
Good general health (controlled conditions)
Smokers (≥10 cigarettes/day for ≥5 years) and never smokers. Confirmation of smoking status will be done via use of a smokerlyzer. The cut-off point for distinguishing smokers from non-smokers is 8 carbon monoxide parts per million (ppm).
Periodontal status: periodontal health, gingivitis on intact or reduced periodontium, treated periodontitis
Uncontrolled periodontal disease
Uncontrolled systemic disease
Pregnancy
Use of therapy and/or medication that impairs wound healing (e.g., bisphosphonates, steroids, chemotherapy, radiotherapy etc.)
Patients scheduled for tooth extraction and alveolar ridge preservation (bone graft and membrane) in the Graduate Periodontics Clinic at Marquette University School of Dentistry.
