Study Notes
Gingivitis and Periodontitis
- The main difference between gingivitis and periodontitis is that gingivitis is a reversible inflammation of the gums, while periodontitis is a more severe infection that can lead to tooth loss.
Bacteria Associated with Periodontitis
- Adult periodontitis is commonly associated with bacteria such as Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, and Tannerella forsythia.
Predisposing Factors for Gingivitis and Periodontitis
- Predisposing factors of the host that are important in the development of gingivitis and periodontitis include genetic factors, smoking, and systemic diseases such as diabetes.
Etiology of Plaque-Induced Gingivitis
- The etiology of plaque-induced gingivitis is the accumulation of bacterial plaque on the teeth, leading to an inflammatory response.
Types of Periodontitis
- The most frequent type of periodontitis is chronic periodontitis, characterized by slow evolution.
- Early-onset periodontitis is characterized by rapid evolution and a poor response to treatment.
Characteristics of Gingivitis and Periodontitis
- Gingivitis is characterized by inflammation and redness of the gums, while periodontitis is characterized by inflammation and destruction of the periodontal tissues.
Bacteria and Periodontal Disease
- Porphyromonas gingivalis produces gingipains that destroy collagen in the periodontal ligament.
- Aggregatibacter actinomycetemcomitans is known for producing toxic metabolites like butyric acid and sulfur compounds.
- Tannerella forsythia can evade the host response by inhibiting B cells and causing destruction of components of the complement system and immunoglobulins.
Pathogenicity and Host Response
- The invasion of periodontal tissue by different bacteria is characterized by a type of pathogenicity that involves the evasion of the host response.
- Hyperresponsiveness leads to an exaggerated inflammatory response, which can contribute to the development of periodontal disease.
Diagnosis of Periodontal Disease
- The detection of intracytoplasmic enzymes in periodontal disease has diagnostic implications for the presence of periodontal pathogens.
- Socransky's postulate states that pathogens are associated with periodontal disease, and if eliminated, the disease would resolve.
- PCR (polymerase chain reaction) allows for the detection of specific bacteria from the periodontal pocket.
- Analyzing gingival fluid and peripheral blood markers can provide diagnostic information for periodontal disease.
Risk Factors and Prevention
- Genetic factors, such as family history, are a risk factor associated with periodontitis.
- Behavioral risk factors, such as smoking, are associated with periodontitis.
- The detection of PGE2 and interleukins in gingival fluid is related to the inflammatory response in periodontal disease.
