Therefore, oral health refers to good oral hygiene, good oral function and no oral diseases.
Causes and prevention of dental caries
Although the cause of dental caries is not completely clear at present, it is preliminarily determined that the occurrence of dental caries is related to the following four factors:
A. the role of bacteria bacteria form plaque on the surface of teeth, decompose sugar in food to produce acid, which leads to demineralization of teeth.
B. food factors: food is too thin and sticky, and it is easy to stick to the tooth surface. The sugar in food is too high, which easily leads to the proliferation of bacteria.
C teeth with obvious anatomical defects (such as deep pits and cracks) or irregular arrangement are easy to cause food accumulation, which is conducive to bacterial reproduction and acid production.
D. the longer the time above the time factor, the higher the probability of caries.
Prevention is the main way to prevent dental caries, and the key to prevent dental caries is to maintain oral hygiene.
A Master the correct method of brushing teeth, form a good habit of brushing teeth after meals, and use dental floss regularly.
B. Conduct oral examination regularly to achieve early detection and early treatment. The treatment of early dental caries is simple, painless and effective. Once dental caries progress to pulp pain, the treatment procedure is complicated, which requires repeated follow-up, resulting in great treatment response and poor dental prognosis.
C. To improve the caries prevention ability of teeth, fluoride toothpaste can be used, and children can also drink fluoride water and rinse their mouths with 0.5% sodium fluoride solution. For children's newly erupted molars, pit and fissure sealing can be performed.
Who needs pit and fissure sealing? When is it suitable for pit and fissure sealing?
1. Generally speaking, deep pits and trenches, especially those that can jam the probe (including suspected caries);
2. The other teeth of the patient, especially the teeth with the same name or tendency to suffer from caries on the opposite side, should be sealed with pit and fissure;
3. It is suitable for pit and fissure sealing when children's teeth reach the occlusal plane after eruption, generally within 4 years after eruption;
4. The best sealing time is: deciduous molars are 3-4 years old, first permanent molars are 6-7 years old, second permanent molars are11-3 years old, and bicuspids are 9- 13 years old.
The method of pit and fissure sealing is very simple, which can be completed by tooth washing, acid etching, tooth washing and air drying, sealing agent coating and curing. After curing, the material is closely attached to the ditch wall, which has certain chewing resistance and is harmless to eating. And after curing, the material is non-toxic and harmless to human body. However, it should be emphasized that pit and fissure sealing requires professional operation and necessary instruments and equipment. The sign of successful pit and fissure sealing is that the sealing agent can exist completely, and it is suspected that it is worn but cannot fall off, so it needs to be checked regularly, and the material falls off and needs to be re-sealed.
What are the possibilities of abnormal tooth color?
1. Enamel hypoplasia: It is caused by poor mineralization during enamel development.
2. Dental fluorosis: Living in areas with high fluorine content for a long time.
3. Tetracycline teeth: Take tetracycline drugs during the mineralization period of tooth development.
4. Dental pulp necrosis: dental pulp infection caused by various reasons and tooth discoloration after necrosis.
5. Tooth coloring: Smoking, drinking tea and coffee will all cause tooth coloring.
When do you need dental implants? What's the harm in not doing it?
Except for a few missing teeth, most missing teeth and complete missing teeth, after proper treatment, the shape and function of teeth can be restored by repairing the dead pulp teeth and residual roots of crown caries. Therefore, the residual roots and crowns should not be pulled out hastily, and it is best to ask a restorer to see if it is valuable. In addition, dental fluorosis, tetracycline teeth and discolored teeth with dead pulp can also be fixed with porcelain to improve their appearance. Generally speaking, it takes 2-3 months to plant teeth after tooth extraction. At this time, the wound healed completely, alveolar bone absorption and reconstruction were completed, and the denture was relatively stable after dental implantation.
Long-term failure to repair missing teeth will not only affect the appearance and pronunciation, but also affect the chewing function. It will also lead to occlusal disorder, secondary temporomandibular joint disease, occlusal trauma, periodontal disease and the health of the remaining teeth.
What is the difference between removable dentures and fixed dentures? Under what circumstances are removable dentures and fixed dentures implanted?
Removable dentures are called removable dentures in medicine, and patients can take them off freely. This kind of denture has the advantages of less cutting and grinding of real teeth, convenient manufacture and low cost, but it is bulky, has a foreign body sensation when worn, and some will affect pronunciation, and has poor stability and limited recovery of chewing function. Fixed denture is a fixed denture, which is stuck in the patient's mouth without taking it off. They have the advantages of small size, stability, firmness, comfort, no influence on pronunciation and effective recovery of chewing function. However, before dental implantation, more natural teeth are cut and ground, and the cost is higher than that of removable dentures.
First of all, the patient's missing teeth should be considered, and the real teeth on both sides of the missing teeth space should also be considered. Generally, when the anterior teeth are missing 1-4, when the real teeth on both sides of the missing tooth space have sufficient height, the root is stable, the tooth tissue is healthy, and the tooth position is normal without inclination and torsion, fixed dentures can be installed. Children with tooth dysplasia, periodontal tissue atrophy, tooth loosening and oblique dislocation are best not to choose fixed denture for restoration. As for removable dentures, most patients can install them.
How old are you to do orthodontics? Can adults do it?
Theoretically, wrong? There is no strict age limit for orthodontic treatment. As long as the periodontal tissue and jaw are in normal physiological anatomy, teeth can move in alveolar bone under the action of orthodontic force to correct malocclusion. .
The best time for orthodontic treatment is about 12 years old. At this time, the tooth replacement has been completed, and the development of craniofacial bone has been completed by 85%-90%. Wrong? The morphology is basically stable, but the patient is still at the peak of growth and development, and the maxillofacial region still has certain growth potential. Tissue reflects good orthodontic force, good orthodontic effect and relatively short course of treatment. But some backbone? Deformed children may need treatment at a younger age and begin treatment at the stage of changing teeth or even deciduous teeth. At this time, the purpose of treatment is to remove all kinds of interference factors that affect the development of bones, and to promote and guide the development of bones in a direction conducive to deformity correction. After tooth replacement, these patients need to receive regular orthodontic treatment and have established a normal dentition. Adults can also receive orthodontic treatment, but the adult bone development has been completed and the tissue has no growth potential. On the one hand, the teeth move slowly, on the other hand, there are some mistakes due to insufficient growth compensation? The correction effect should be discounted. In addition, adults often have dental caries, periodontal disease, temporomandibular joint disease, tooth loss, etc., and there may even be some general health factors that need to be considered in the design and treatment process. However, adults generally have the initiative in treatment and can actively cooperate with treatment. Therefore, as long as the periodontal health is good, satisfactory results can be obtained, and the course of treatment has not been significantly prolonged.
1 Why do you need regular oral examination?
Common oral diseases (such as dental caries and periodontal diseases). Most of them are chronic diseases, and the early symptoms are not obvious, which is easy to be ignored. Therefore, regular oral health examination is helpful for early detection, early diagnosis and early treatment.
The time limit standard of regular check-up varies with age, usually: children aged 2- 12 are checked once every six months; 12 years of age or older, physical examination once a year; Pregnant women can have a checkup every two to three months.
Why use disposable equipment and one person and one machine?
During oral treatment, the instrument is in direct contact with the saliva and blood of the patient. Use disposable instruments and international standard mobile phone disinfection equipment to ensure sterility, completely cut off the source of infection, and let you receive treatment with peace of mind.
3 why do you want to wash your teeth?
Due to long-term failure to wash teeth, tartar deposits to form tartar, which will cause gum swelling, bleeding and bad breath when brushing teeth, and will also lead to periodontitis, tooth loosening and falling off. Tooth washing should be carried out regularly, preferably from 6 months to 1 year.
4. Why should missing teeth be repaired on time?
Tooth can be restored 2.5 ~ 3 months after tooth extraction. If the missing teeth are not repaired in time, it may cause the following adverse consequences: (1) the adjacent teeth move and tilt towards the missing teeth space; (2) Maxillary tooth elongation can easily lead to food blockage, root exposure and dental caries; (3) The gingival atrophy and alveolar bone absorption in the edentulous part make it difficult to repair in the later stage; (4) affect the appearance and pronunciation; (5) Tooth loss causes food to be chewed, which is easy to cause digestive system diseases.
5 What are the hazards of dentofacial deformities?
Dentofacial deformity, also known as malocclusion, refers to abnormal dentition, which can be manifested as abnormal tooth arrangement, such as torsion, inclination, access or crowded disorder. And even if the dentition is arranged neatly, the occlusal relationship between the upper and lower teeth is abnormal, which leads to the protrusion of the upper teeth (commonly known as buckteeth) or the protrusion of the lower dental arch (commonly known as the floor cover).
Since it is deformed, it will first destroy a person's appearance. Severe dentofacial deformities will also make some patients feel pessimistic, thus causing psychological and mental disorders, which may also have a negative impact on job hunting, chewing, pronunciation, swallowing and oral hygiene maintenance, and increase the possibility of dental caries and periodontal disease.
Generally speaking, skeletal deformities should be corrected as soon as possible. If the teeth are not aligned, it is best to treat them at the age of 12- 17. Adults with 18 or above can correct dentition as long as their periodontal condition is good. .
