What is marginal periodontitis?
Marginal periodontitis is a disease of the marginal periodontium characterized by inflammation and resorption of the alveolar crest. Clinically it must be differentiated from gingivitis and senile atrophy.
What is marginal gingivitis?
Accumulations of dental plaque adjacent to the gingival margin which result in gingival inflammation have been termed marginal gingivitis. Recently an international consensus report defined gingival disease. The two broad categories were plaque-induced disease and non-plaque-induced disease.
What is the periodontium of teeth?
The periodontium is a complex structure composed of the gingiva, periodontal ligament (PDL), cementum, and alveolar bone (Figure 11-1). The primary functions of the periodontium are to allow the tooth to be attached to the bone and to provide a barrier for the underlying structures from the oral microflora.
How is marginal gingivitis treated?
The treatment of marginal gingivitis is basically to remove all the accumulations of food debris so that the intensity of the bacterial attack is reduced.
What is alveolar crest?
The alveolar crest is the most cervical rim found in the alveolar bone proper. When it is healthy, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by about 1.5-2 mm. The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy.
Is gingivitis serious?
Gingivitis is an inflammation of the gums, usually caused by a bacterial infection. If left untreated, it can become a more serious infection known as periodontitis. Gingivitis and periodontitis are major causes of tooth loss in adults, according to the American Dental Association.
How long does it take to reverse gingivitis?
Treatment Time for Gingivitis But for those with gingivitis due to poor oral hygiene, the average time it takes for gingivitis to go away is about 10 to 14 days after your treatment, along with proper oral healthcare.
What are the 4 components of the periodontium?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
What is periodontium Slideshare?
The tissues that surround and support the teeth are known as the periodontium. It includes: 1- The gingiva. 2- The periodontal ligament. 3- The root cementum. 4- The alveolar bone.
How long does it take for gums to heal from gingivitis?
Is alveolar bone cancellous?
The trabecular bone contains cancellous bone, which is located between the alveolar bone proper in addition to the plates of cortical bone. The alveolar bone is located between two neighboring teeth is the interdental septum.
Marginal periodontitis is a disease of the marginal periodontium characterized by inflammation and resorption of the alveolar crest. Clinically it must be differentiated from gingivitis and senile atrophy.
What is the structure of periodontium?
Periodontium is a complex structure, consisting of epithelial tissue (gum) and connective (periodontal ligament) and mineralized tissue (cementum and alveolar bone) (Figure 15.6 ).
What are the two mineralized tissues of the periodontium?
The two mineralized tissues, cementum and alveolar bone, are the abutments to which the fibrous periodontal ligament anchors the tooth into the skeleton. The gingiva is the covering tissue of the periodontium and offers immediate protection for the underlying tissues as well as additional attachment of the tooth.
What are the radiographic changes seen in periodontal disease?
As bone is lost, the center of rotation moves toward the apex Normal Anatomy Normal Anatomy Radiographic Changes seen in Periodontal Disease Periodontal disease causes inflammatory lesions in the marginal bone Both osteoblastic and osteoclastic activity is seen Osteoclastic activity will cause changes in the morphology of the crestal bone
