What is the periodontium made up of?
What is the periodontium made up of?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
What is periodontal tissue?
Periodontal tissues include four defined structures: gingiva, cementum, alveolar bone, and the periodontal ligament. The following landmarks are crucial to the understanding of the support structures of the tooth and the aetiopathogenesis of periodontal disease.
What are the connective tissues that surround and support the teeth?
The periodontium is the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones. The word comes from the Greek terms περί peri-, meaning “around” and -odont, meaning “tooth”.
How the tooth is related to its periodontium?
The teeth are connected with the walls of the tooth sockets and anchored in the jaws by the periodontal ligament and the cementum. The ligament is made up of connective tissue and contains collagen fibers. These fibers are especially strong so that the teeth can withstand the great pressure put on them while we chew.
What is the main cause of periodontal disease?
Periodontal (gum) disease is an infection of the tissues that hold your teeth in place. It’s typically caused by poor brushing and flossing habits that allow plaque—a sticky film of bacteria—to build up on the teeth and harden.
What is a healthy periodontium?
Using our current knowledge base as well as cultural standards and values, the proposed definition of a healthy periodontium, in a state of wellness, should include simple characteristics that are coherent in allowing an individual to attain positive goals consistent with a positive quality of life (Figure 1).
What is the first tissue to be destroyed in periodontal disease?
In some people, gingivitis progresses to periodontitis – with the destruction of the gingival fibers, the gum tissues separate from the tooth and deepened sulcus, called a periodontal pocket.
What is the hardest substance in the human body?
Tooth enamel
1. Tooth enamel is the hardest substance in the body. The shiny, white enamel that covers your teeth is even stronger than bone. This resilient surface is 96 percent mineral, the highest percentage of any tissue in your body – making it durable and damage-resistant.
How deep are your teeth roots?
It’s in the sulcus that our bodies fight bacteria, called plaque, that collect on the teeth. In a healthy mouth, the sulcus measures between 1 and 3 millimeters. In a mouth that is fighting infection caused by bacteria, the gum tissue recedes and the sulcus deepens to 4 millimeters or more.
Are teeth anchored in bone?
The jaw bone, also called the alveolar bone, is the bone that contains the tooth sockets and surrounds the teeth’s roots; it holds the teeth in place.
What are the 4 stages of periodontal disease?
Periodontal disease is broken up into four separate stages: gingivitis, slight periodontal disease, moderate periodontal disease, and advanced periodontal disease.
Can periodontitis be stopped?
Periodontitis can only be treated but cannot be cured. Gingivitis, on the other hand, can be prevented by maintaining proper oral hygiene practices and visiting the dentist for checkups and exams.
