Necrotizing Periodontal Diseases
Necrotizing periodontal (NPD) include necrotizing ulcerative gingivitis
(contest) and necrotizing ulcerative periodontitis (NUP). Today there is enough evidence to establish whether necrotizing ulcerative necrotizing ulcerative gingivitis and periodontitis-two unique diseases or different stages of the same disease that progresses from the results of the contest on the stump. As long as the difference between necrotizing ulcerative necrotizing ulcerative gingivitis and periodontitis can be clarified, the results of the competition and of the tap are classified together under the category of necrotizing periodontal disease. Both the results of the competition and tap relating to reduce systemic resistance to bacterial infection.
1. Necrotizing periodontal (NPD) is an inflammatory and destructive infection of periodontal tissues, including tissue necrosis (localized tissue death). Both the results of the competition and tap painful infections, sores, swelling, and excessive off dead epithelial tissue of the gums.
A. Necrotizing ulcerative gingivitis (the results of the competition)-tissue necrosis, limited gingival tissues (box 17-7).
B. Necrotizing ulcerative periodontitis (NUP)-tissue necrosis gum tissue combined with loss of attachment and alveolar bone loss (box 17-8).
1. NUP is a painful infection is characterized by necrosis of tissues of the gums, periodontal ligament and alveolar bone.
2. NUP is extremely quick and destructive forms of periodontitis, which may produce a loss of periodontal attachment in a few days.
2. Alternative Terminology. These conditions were previously known as trench mouth, Vincent infection, acute necrotizing ulcerative gingivitis (ANUG), and necrotizing ulcerative gingivostomatitis.
3. The signs and symptoms of Necrotizing periodontal disease
And verbal signs and symptoms. The clinical picture necrotizing periodontal noticeably different from any other periodontal disease [18-20].
1. Necrotizing periodontal disease is a painful infection in the first place, with the participation of interdental and marginal gums.
2. Necrotizing periodontal disease is characterized and ulcerative necrotic and gingival papilla field, pretending papillae and gums fields were "black" or "craters" (Fig. 17-8). At the ulcer margin is washed by the red halo.
3. Necrotic areas of the gums covered with yellowish-white or grey fabric Slough, which is called pseudomembrane.
a. In pseudomembrane consists mainly of fibrin and necrotic tissues with leukocytes, erythrocytes, and the masses of bacteria. (Fibrin is sticky protein formed in the process of formation of blood clots.)
B. The term, pseudomembrane, however, is misleading, because the bog is no consistency and not like a real membrane. This is easily wiped off with gauze, exposing area of fiery red, shiny gums.
c. In pseudomembrane can lead to gum several teeth or she can cover all of the gums.
d. In sloughing off dead gingival epithelium sets out the connective tissue.
4. Fiery red gums with spontaneous or bleeding, bleeding gums, so gentle touch.
5. Necrotic lesions develop quickly and painfully. Intensive oral pain causes patients to seek dental treatment. This symptom is unusual as gingivitis and periodontitis, as a rule, are not painful.
6. First lesions are often found interproximally in front of the lower jaw with a sextant, but can occur in either remove deposits papilla. As a rule, the nipples swell quickly and develop a rounded contour (Fig. 17-9).
7. Pronounced, stinking oral smell (bad breath)may be present, and can vary in intensity and in some cases it is not very noticeable.
a. Pain associated with necrotizing periodontal usually causes a person to stop brush.
B. Materia Alba, memorial plaque biofilm, folded tissue, blood, and stagnation to collect saliva in the mouth, causing oral smell.
8. Necrotizing periodontal disease may be associated with excessive salivation.
9. As developing tissue necrosis, remove deposits are formed craters.
a. For several days, participate papillae often divided into one personal and one speaking part with necrotic depression between them.
B. This Central destruction of the tissue between the skin and speaking part papilla results in interdental crater.
c. After removal of sediments are formed craters, pathological process usually involves the periodontal ligament and alveolar bone, resulting in loss of investment.
d. Deep craters in interdental alveolar bone characterize necrotizing ulcerative periodontitis.
e. In deep periodontal pockets seen in other forms of periodontitis are not common in the tap because tissue necrosis destroys limit epithelial and connective tissue, as a result of the recession gingival edge (Fig. 17-10). The progression remove deposits in the disease process often leads to the destruction of most of bone tissue interdental.
10. The result is pain, it is often difficult for patients to eat.
B. systemic signs and symptoms
1. Swollen lymph nodes, especially in the submandibular and cervical lymph nodes can occur in the NDP.
2. Fever and malaise is not the essential characteristic of the NPD. Studies show that a fever is not common [21,22].
