Cause of periodontal disease is more complex, the total is divided into two aspects of local and systemic factors. Local factors have a very important role in systemic factors can affect the pe 00004000 riodontal tissues of the local stimuli between the two are closely related.
Periodontal local factors:
1. Plaque is the adhesion of microorganisms on the surface of the teeth, can not use mouthwash, water washed to remove. It is well established, plaque is the initiating factor of periodontal disease, periodontal disease is caused by a major factor.
2. Calculus is deposited on the tooth surface mineralization of plaque. Calculus and according to its deposition site and are divided into supragingival calculus and subgingival calculus two. Subgingival calculus on the teeth at the gingival margin above the surface, the naked eye can be seen directly. Deposition Dental Reviews in the neck more teeth, especially in the large salivary duct openings, such as opposite the maxillary molar buccal and lingual mandibular anterior teeth deposition more.
Subgingival calculus in the gingival margin below the gingival or periodontal pocket bags of root surface, the naked eye can not look straight into the probe with the probe must be before they can know the location and deposition of sediment. Subgingival calculus on the teeth can be in any form, but more proximal and lingual.
Subgingival plaque is the main source of inorganic salts in saliva of calcium, phosphorus and other mineral salts. Subgingival calculus is mainly exudate in gingival crevicular fluid and mineral salts available.
Calculus of the periodontal tissue damage, mainly because it constitutes a plaque and bacteria attached to a good environment. Calculus itself impede the maintenance of oral hygiene, to more accelerated plaque formation, the formation of stimulating the gum tissue.
3. Occlusion in occlusal trauma, if the direction of bite force is too large or unusual, beyond the periodontal tissue can withstand the force, resulting in periodontal tissue damage bite, called traumatic occlusion. Traumatic What is the relationship of protein and caries occlusion bite from time to time, including early contact, occlusal interference, such as teeth at night.
4. Others include food impaction, poor restorations, mouth breathing and other factors also contributed to the periodontal inflammatory process.
Periodontal disease systemic factors:
The occurrence of periodontal disease, local factors are the main. Systemic factors in the development of periodontal disease are promoting factor, systemic factors can reduce or change
