Gingivitis and periodontitis - causes, symptoms, diagnosis, treatment, pathology
TLDRGingivitis and periodontitis are dental conditions that involve inflammation and potential damage to the gums and tooth-supporting structures. Gingivitis, characterized by red, swollen, and bleeding gums, is a reversible condition caused by bacterial imbalance in the mouth, leading to the formation of dental plaque. If left untreated, it can progress to periodontitis, a more severe disease with a higher concentration of pathogenic bacteria, resulting in periodontal pockets, immune response issues, and possible tooth loss. Diagnosis is typically done through visual inspection, X-rays, and probing, while treatment ranges from daily oral hygiene to antibiotics and surgery for severe cases.
Takeaways
- 🦷 **Gingivitis and Periodontitis**: Gingivitis is inflammation of the gums, while periodontitis is inflammation and destruction of the tooth's supporting structures.
- 🔄 **Spectrum of Disease**: The conditions range from simple gingivitis to more severe periodontitis if left untreated.
- 💡 **Anatomy of a Tooth**: The tooth and its structures include the mandible, maxilla, alveolus, periodontal ligament, root, cementum, neck, crown, and enamel.
- 🌱 **Gingival Crevice**: The space between the free gingiva and the crown where gingival crevicular fluid, containing immune cells and proteins, flows.
- 🦠 **Bacterial Balance**: A healthy mouth maintains a balance of commensal bacteria, which is disrupted in gingivitis and periodontitis due to an increase in pathogenic bacteria.
- 🧑🔬 **Dental Plaque Formation**: Plaque is a biofilm of bacteria, saliva proteins, and dead mouth cells that can lead to inflammation if not removed.

Q & A
What is the medical term for inflammation of the gums?
-The medical term for inflammation of the gums is 'gingivitis'.
What does 'peri-' mean in the context of periodontitis?
-'Peri-' means around, so in 'periodontitis', it refers to inflammation and destruction around the tooth.
What is the bone beneath the bottom row of teeth called?
-The bone beneath the bottom row of teeth is called the mandible.
What is the term for the socket that holds each tooth in the jawbone?
-The socket that holds each tooth in the jawbone is called an 'alveolus'.
What is the name of the soft tissue that covers the alveolus on the outside?
-The soft tissue that covers the alveolus on the outside is called the 'gingiva' or gums.
What is the hardest substance in the human body?
-The hardest substance in the human body is 'enamel', which covers the crown of the tooth.
What is the space between the free gingiva and the crown called?
-The space between the free gingiva and the crown is called the 'gingival crevice' or 'gingival sulcus'.
What is the term for a state of imbalance in the mouth's bacterial organisms?
-The term for a state of imbalance in the mouth's bacterial organisms is 'dysbiosis'.
What is dental plaque and how does it form?
-Dental plaque is a sticky collection of bacteria, proteins from saliva, and dead cells from the mouth's lining. It forms when individual bacteria multiply to create microcolonies that coalesce into a biofilm.
How does dental calculus contribute to the development of gingivitis?
-Dental calculus creates a hard mass that is difficult to remove, providing a space for bacterial plaque formation, which can then invade the gingival sulcus and cause inflammation or gingivitis.
What are the typical symptoms of gingivitis?
-The symptoms of gingivitis typically include redness, swelling, and bleeding of the gums, especially after brushing or flossing.
How is periodontitis diagnosed and what treatment options are available?
-Periodontitis is diagnosed by visual inspection for swollen or bleeding gums, probing the gingival sulcus to determine depth, and X-rays to evaluate bone levels. Treatment can range from daily brushing and flossing to the use of antimicrobial agents, and in severe cases, antibiotics and surgery may be necessary.

🦷 Understanding Gingivitis and Periodontitis
The first paragraph explains the medical terms 'gingivitis' and 'periodontitis', which refer to inflammation and destruction of gum and tooth-supporting structures, respectively. It describes the anatomy of the mouth, including the mandible, maxilla, alveolus, periodontal ligament, and gingiva. The tooth is divided into the root, neck, and crown, with the root covered by cementum and the crown by enamel. The gingival crevice is where gingival crevicular fluid, containing immune cells, is found. The balance of bacteria in the mouth is crucial, and an imbalance can lead to the formation of dental plaque and biofilm, which can cause gingivitis. If left untreated, gingivitis can progress to periodontitis, which is characterized by more severe bacterial dysbiosis and damage to the gums and supporting structures. The paragraph also discusses the role of dental calculus in plaque formation and the immune response in the progression of these diseases.
🦠 Bacterial Complexes and Their Role in Periodontitis
The second paragraph delves into the progression of periodontitis, focusing on the role of specific bacterial complexes. It introduces the 'orange-complex' and 'red-complex' of bacteria, which are associated with the disease's development. The red-complex includes Tannerella forsythia, Treponema denticola, and Porphyromonas gingivalis (P. gingivalis), known for impairing immune cells. The paragraph suggests that it's not just the presence of these bacteria but the overall shift in the bacterial community that leads to periodontitis. The immune response to these bacteria results in a periodontal pocket, further damaging the gingival cells. The release of chemicals like histamine and substance P causes swelling, while cytokines like interleukin-1 attract more immune cells, escalating the inflammation. P. gingivalis's ability to hinder the immune system allows other bacteria to thrive. The immune response and bacterial activity create a feedback loop that exacerbates the infection. Osteoclasts are activated, leading to bone dissolution and tooth loosening. Symptoms of gingivitis include redness, swelling, and bleeding, but some individuals may not show signs, especially early on. If severe, periodontitis can result in tooth loss. Diagnosis involves visual inspection, probing, and X-rays to assess bone levels. Treatment ranges from daily oral hygiene to antibiotics and surgery for severe cases.

Highlights
Gingivitis refers to the inflammation of the gums, while periodontitis involves inflammation and destruction of the tooth's supporting structures.
The spectrum of gum diseases ranges from simple gingivitis to more severe periodontitis if left untreated.
The mandible and maxilla are the bones that support the teeth, each featuring an alveolus or socket for each tooth.
The periodontal ligament lines the alveolus, attaching to the cementum covering the tooth's root.
The gingiva, or gums, are a layer of soft tissue that protect the alveolus and sit on top of the bone.
The tooth is divided into the root, covered by cementum, and the crown, which is visible and covered in enamel.
Enamel is the hardest substance in the human body due to its high mineral content.
The free gingiva is the portion of the gum not anchored to the tooth, and the space between it and the crown is the gingival crevice.
Gingival crevicular fluid, containing immune proteins and cells, flows into the gingival crevice.
A healthy mouth maintains a balance of commensal bacteria, kept in check by the mouth's immune factors.
Gingivitis and periodontitis result from an imbalance of bacteria, or dysbiosis, leading to a relative increase in pathogenic bacteria.
Dental plaque is a biofilm formed by pathogenic bacteria, saliva proteins, and dead mouth cells.
Bacteria in a biofilm communicate and work together, creating a complex system for survival and nutrient acquisition.
Dental calculus, a hard mass that forms from dental plaque, provides an environment for further bacterial growth and inflammation.
Gingivitis is characterized by redness, swelling, and bleeding of the gums, and is often reversible with treatment.
Periodontitis involves a more extreme dysbiosis with flourishing disease-causing bacteria, potentially leading to tooth loss.
The presence of specific bacterial complexes, such as orange- and red-complex bacteria, are associated with the progression of periodontitis.
The immune response in periodontitis can cause further damage, leading to a feedback loop that exacerbates the infection.
Diagnosis of gingivitis and periodontitis involves visual inspection, probing the gums, and X-rays to evaluate bone levels.
Treatment options range from daily oral hygiene and antimicrobial agents to antibiotics and surgery for severe cases.
