Study Notes
Smoking and Periodontitis
- Smoking significantly increases the risk of periodontitis, influencing prevalence, extent, and severity.
- Clinical outcomes for both surgical and non-surgical treatments may be adversely affected by smoking.
- The long-term success of dental implants is compromised in smokers.
- Tobacco smoke contains harmful compounds like carbon monoxide, hydrogen cyanide, and nicotine, which may modify the host response in periodontitis.
Classification of Smokers
- Current smokers: Individuals who have smoked 100 or more cigarettes in their lifetime and continue to smoke at the time of the assessment.
- Former smokers: Individuals who have smoked 100 or more cigarettes but have quit smoking.
- Non-smokers: Individuals who have never smoked 100 or more cigarettes.
- Light smokers: Individuals who smoke fewer than 19 cigarettes daily.
- Heavy smokers: Individuals who smoke 19 or more cigarettes daily.
Forms of Tobacco
- Smoking tobacco: Includes cigarettes, cigars, pipes, hookah, and beedis.
- Smokeless tobacco: Comprises products like guthka, pouch, khaini, and snuff.
Nicotine and Its Local Effects
- Nicotine, an alkaloid in tobacco, makes up about 0.6-3.0% of tobacco's dry weight.
- It causes vasoconstriction, impairing blood flow to the gums, which negatively impacts healing in periodontal procedures.
Effects of Smoking on Periodontal Disease
- Gingivitis: Smokers exhibit reduced inflammatory response to plaque, leading to less gingival bleeding.
- Gingival blood flow: Smokers show less bleeding on probing due to nicotine’s vasoconstrictive effects.
- Periodontitis: Increased severity and prevalence of periodontal issues like pocket depth, attachment loss, and alveolar bone loss in smokers compared to non-smokers.
Notable Impacts of Smoking
- Gingivitis leads to decreased gingival inflammation and probing bleeding.
- Periodontitis results in a higher rate of periodontal destruction, increased pocket depth, attachment loss, and tooth loss.
- Severity of periodontal disease correlates with the amount smoked daily.
- Smoking cessation leads to a decrease in the prevalence and severity of periodontal disease.
Pathogenesis and Etiology of Periodontal Disease
- Smoking alters host-bacterial interactions, causing more aggressive periodontal breakdown.
- Changes in subgingival plaque composition or host responses contribute to this increased destruction.
Effects on Plaque Development
- Smokers typically have higher dental plaque prevalence, correlating with more severe periodontal disease.
- Smoking may lower the resting flow rate of gingival crevicular fluid (GCF), impacting periodontal health.
Microflora Changes in Smokers
- Research indicates that smokers have a distinct subgingival microflora, potentially contributing to their increased periodontal disease risk.
