Causes and Grades of Calculus Formation
The
appearance of dental calculus in the mouth is mainly due to the minerals
contained in human saliva, which reacts with the acid secretions in the oral
cavity. The physiological needs of a person determine that a large amount of
saliva must be secreted every day.
Due
to the secretion of saliva, the minerals in the saliva have the conditions for
long-term continuous reaction with the oral acidic liquid. As a result of this
long-term reaction, acidic compounds are generated and become the cause of the
formation of tooth "stone". These reactants are easily attached to
the tooth surface , Or the joints between gums and teeth, which are difficult
to clean when brushing your teeth. After a long time, it becomes a stubborn derivative-calculus.
Dental
calculus usually exists on the surface of the teeth at the opening of the
salivary glands (such as the lingual surface of the anterior teeth of the jaw,
the buccal surface of the posterior teeth of the upper jaw) and the neck of the
teeth, and the surface of the teeth where the oral mucosa cannot move.
Dental
calculus is soft at first and will harden due to gradual calcification. It is
composed of 75% calcium phosphate, 15-25% water, organic matter, manganese
phosphate, calcium mineralate and trace amounts of potassium, sodium, iron, and
appears yellow, brown, or black. There are several reasons for its formation:
1.
The concentration of carbon dioxide in saliva is reduced, which promotes the
precipitation of inorganic salts on the tooth surface.
Second,
the phosphate enzymes of the degenerated cells hydrolyze the organic phosphorus
to produce phosphorus precipitated on the tooth surface.
3.
The bacteria make saliva's acidity and alkalinity increase to be alkaline,
causing the protein in saliva to decompose, release calcium salts, and deposit
on the surface of teeth.
4.
It is related to the saliva concentration. The greater the concentration, the
easier it is to settle. The rate, shape and hardness of dental calculus vary
from person to person. Generally speaking, it takes twelve to fifteen hours for
new calculus.
Fast-forming
calculus is softer and more broken than slowly-forming calculus. The resulting
calculus is soft and soft, and after a period of calcification, it will
gradually harden. Between derivatives and derivatives, there is a mixed state
between physiological and physical. So far, it seems that there is no way in
the world to remove stains and calculus from teeth except for tooth cleaning.
That is, tooth cleaning is the only effective way to remove stains and calculus
quickly.
Dental
calculus is a foreign object to the oral cavity. It will continuously stimulate
the periodontal tissues, and it will compress the gums and affect the blood
circulation, causing bacterial infection of the periodontal tissues, causing
inflammation and shrinkage of the gums, forming periodontal pockets. When the
periodontal pocket is formed, it is easier to accumulate food debris, plaque,
and calculus. This new accumulation further destroys the deeper periodontal
membrane. The result of such a continuous vicious cycle ends in the tooth. The
Zhou support organization was completely destroyed, making it difficult for
teeth to escape the bad luck.
How
to prevent the formation of dental calculus?
Brushing
your teeth is a simple and effective method to prevent the formation of
calculus. The deposition of dental calculus is gradually formed from few to
many. Regular brushing can remove tartar and calculus that have just started to
deposit on the tooth surface. Therefore, children should be allowed to brush
their teeth persistently. If the calculus is thick and adheres tightly, it
cannot be brushed off and must be removed by the dentist.
In
addition, due to the high viscosity and heavy sugar content of fine food, it is
easy to deposit on the tooth surface. Therefore, children should be warned to
eat less fine food, or to brush their teeth after eating. In particular, eating
fine foods such as biscuits and cakes before bedtime is not only easy to form
calculus, but also can cause caries. Therefore, we must develop a good habit of
brushing teeth and maintaining oral hygiene.
Treatment
of dental calculus
1.
Brush your teeth
Brushing
your teeth sooner or later and gargle after meals are the most important measures
to prevent the formation of calculus. Use a health toothbrush, use fluoride
toothpaste, use the correct method-vertical brush method to brush teeth,
correct the horizontal brush method. This not only removes food debris, dental
plaque, tartar and dirt, prevents the formation and deposition of calculus, but
also massages the gums, promotes blood circulation, and enhances the disease
resistance of periodontal tissues.
2.
Diet
Reasonable
nutrition, matching thickness. Eat more vitamin-rich crude fiber foods, such as
meat, eggs, various vegetables and fruits, and chew fully to help clean the
teeth. Eat less sweets and sticky foods, and no snacks.
3.
Wash your teeth
Ultrasonic
tooth cleaning is aimed at removing parts of tooth stones. Because calculus is
more likely to cause the accumulation of dental bacteria, causing gingivitis,
bleeding gums, and periodontal disease, it is a medical act to remove calculus.
You need to wash your teeth 1-2 times a year.
Of
course, at the same time of treatment, the stones on the tooth neck and the
adjacent surface are removed, and the teeth will be slightly whitened. It is
worth mentioning that at present, some people are driven by economic interests
and do not clean their teeth without systematic formal learning and training. The
technical level and equipment disinfection measures do not meet the
requirements. Can not achieve the purpose of cleaning teeth, and it is easy to
cause cross infection, so if you need to clean your teeth must go to regular
hospitals and clinics.
Grade
of calculus
Clinicians
and researchers often use the amount of calculus as one of the indicators for
studying periodontal disease; individuals can understand the amount of calculus
to measure the quality of their own brushing and use it as a reference for
cleaning the oral cavity.
1
degree: a little soft dirt or calculus, but not more than l/3 of the tooth
surface.
2
degrees: There are calculus, and it is more than 1/3 of the crown surface, and
there are a few subgingival stones.
3
degrees: dental calculus does not exceed 2/3 of the crown surface, there are
more subgingival stones.
4
degrees: The calculus is about the same size as the tooth, and it is rare in
the clinic.
