More complex causes of periodontal disease, the total is divided into local and systemic factors in two aspects. Has a very important role in local factors, systemic factors can affect the periodontal tissues of the local stimuli between the two are closely related.

Local factors

1. Dental plaque is the adhesion to the surface of microorganisms, can not use mouthwash, water washed to remove. Is now recognized that plaque is a dynamic factor beginning of periodontal disease is the major pathogenic factor in causing periodontal disease.

2. Calculus is deposited on the tooth surface mineralization of dental plaque. Calculus also according to their location and nature of the sediment is divided into subgingival calculus and subgingival calculus on the two kinds. Gingival calculus in the gingival margin on the tooth surface more than the naked eye can be seen directly. Deposition in the neck, more teeth, especially in the large salivary duct openings, such as opposite to the buccal side of maxillary molars and mandibular anterior teeth lingual deposition more. Subgingival calculus in the gingival margin below the gingival or periodontal pocket bag the root surface, the naked eye can not look straight, we must use probe exploration, can only idea on the location and deposition of sediment volume. Subgingival calculus on the teeth can be in any shape, but more adjacent surfaces and lingual.

Supragingival plaque is the major source of inorganic salts in the saliva of calcium, phosphorus and other mineral salts. Subgingival calculus is mainly gingival crevicular fluid and exudate to provide mineral salts.

Calculus of the periodontal tissue damage, mainly that it constitutes a plaque and bacteria attached to a good environment for breeding. Calculus itself hampered the maintenance of oral hygiene, which further accelerated the formation of plaque on the gingival tissues to stimulate the formation of.

3. Traumatic occlusion in the occlusion, if the direction of bite force is too large or unusual, beyond the periodontal tissues can bear together, resulting in periodontal tissue damage occurs bite, known as the traumatic occlusion. Traumatic occlusion from time to time, including the early occlusal contacts, occlusal interference, such as night-time teeth.

4. Others include food impaction, poor restorations, mouth breathing and other factors also contributed to the process of periodontal tissue inflammation.

Systemic factors

The occurrence of periodontal disease, local factors are dominant. Systemic factors in the development of periodontal disease are promoting factor, systemic factors that can reduce or change the periodontal tissue resistance to external stimuli to make it vulnerable to disease and may contribute to the development of gingivitis and periodontitis.

Systemic factors include: endocrine disorders, such as sex hormones, adrenal cortical hormone, thyroid hormone secretion such as abnormal. Diet and nutrition may have a lack of vitamin C, vitamin D and calcium, phosphorus, or the lack of imbalances, malnutrition. Blood disease and the close relationship between periodontal tissue, leukemia patients often appeared swollen gums, ulcers, bleeding. Hemophilia spontaneous bleeding gums may occur. The long-term use of certain drugs such as phenytoin can occur fibrous gingival hyperplasia; of certain types of periodontal disease, such as adolescents tend to have a family history of periodontitis, thus considering genetic factors. In short, the cause of periodontal disease more complicated, in the treatment not only to pay attention to the elimination of local factors, but also taking into account the state of the body in order to obtain a better therapeutic effect.
