What is alveolar bone loss?
Cumulative alveolar bone loss results in a weakening of the supporting structures of the teeth and predisposes the patient to tooth mobility and loss. It is one of the hallmarks of periodontitis.
What is the new periodontal classification?
The new classification, which introduces the concept of staging, supports a multidimensional view of periodontitis, incorporating severity, tooth loss due to periodontitis, and complexity of management of the patient’s periodontal and overall oral rehabilitation needs.
How do you calculate RBL?
Staging severity using RBL calculation:
- CEJ to the Apex of the Root – 2mm = Healthy Bone Level.
- Current Bone Height to the Apex of the Root = Current Bone level.
- Healthy Bone Level – Current Bone Level = Bone Loss Level.
- (Bone Loss Level ÷ Healthy Bone Level) x 100 = % Bone Loss.
What are the three categories of periodontal health?
Staging of periodontitis:
- Stage I (initial)
- Stage II (moderate)
- Stage III (severe with potential for additional tooth loss)
- Stage IV (severe with potential for loss of dentition)
What type of bone is alveolar bone?
Although the alveolar process is made up of compact bone, it may also be called the cribriform plate as it contains various holes where Volkmann canals pass from the alveolar bone and into the PDL. The alveolar bone proper is also called the bundle bone because of the Sharpey fibers.
How is alveolar bone loss treated?
Treating Alveolar Bone Loss The process provides a sound structure for the implants and helps stimulate the bone to grow and rebuild itself. Bone grafting can also be used to repair damaged and lost bone around any teeth with deep pockets caused by gum disease.
What is Cal in dentistry?
Clinical attachment loss which is also known as CAL, is the presence of periodontal disease. Periodontal disease, or gum disease, is a set of inflammatory conditions which affect the tissues that surround the teeth. In the early stage, the condition is called gingivitis.
What is RBL in dentistry?
The process of classifying the severity of a patient’s disease. The primary determinant = clinical attachment loss (CAL) at the point of greatest loss (the worst tooth). If CAL not available, radiographic bone loss (RBL) can be used.
What is RBL in periodontal disease?
Initial stage should be determined using clinical attachment loss (CAL). If CAL is not available, radiographic bone loss (RBL) should be used. Tooth loss due to periodontitis may modify stage definition. One or more complexity factors may shift the stage to a higher level.
How do you classify reduced Periodontium?
Clinical gingival health on a reduced periodontium is characterized by an absence of bleeding on probing, erythema, edema and patient symptoms in the presence of reduced clinical attachment and bone levels….
| Reduced periodontium | ||
|---|---|---|
| Non-periodontitis patient | Health | Gingivitis |
| Radiological bone loss | Possible | Possible |
What are the classification of gingivitis?
Two broad categories of gingival diseases include dental plaque-induced gingivitis and non-dental plaque biofilm-induced gingival diseases.
What is the alveolar bone made of?
calcium hydroxyapatite crystals
Composition. Inorganic matrix: The alveolar bone is made up of 67% inorganic material by its weight. The inorganic material is primarily composed of calcium and phosphate. The mineral content is typically in the form of calcium hydroxyapatite crystals.
Which of the following has been linked to alveolar bone loss?
Periodontal disease , also known as gum disease is the major cause of this condition, which makes gum disease treatment an important step in preventing alveolar bone loss.
