With the increasing popularity of oral hygiene knowledge, people are paying more and more attention to the cleanliness and beauty of their teeth. Dental clinics often encounter patients who ask for “scaling”. The so-called “scaling” is the medical term “oral scaling”, not only for the aesthetic cleaning of teeth, in fact, it is a periodontal disease treatment, here to talk about the knowledge of this area, so that we can better dental We would like to talk about this so that we can have better dental care. Due to the environment in which the teeth are located, the tooth surface is often deposited by salivary proteins, bacteria, food debris and other soft film deposits, if these deposits are not thoroughly removed in a timely manner, calcium and phosphorus ions in the saliva will be deposited, forming hard, calcified, can not be brushed away calculus, in the food or drink under the influence of pigment and turn black or yellow, affecting the beauty of teeth. Tartar is often deposited on the surface of the teeth or at the gingival margin of the neck of the teeth, where it is not easily brushed. The presence of calculus hinders oral hygiene and often causes oral odor; calculus itself and its surface bacteria and bacterial metabolites stimulate gingival and periodontal tissues, causing gingivitis, periodontitis, periodontal abscess, bleeding from brushing, bad breath, etc.; too much calculus deposition presses the gums and alveolar bone to recede, resulting in root exposure, loose teeth, and no chewing. The excessive deposition of dental calculus can press on the gums and receding alveolar bone, leading to root exposure, loose teeth, chewing weakness, etc. Therefore, calculus is the main cause of the development of periodontal disease, and timely removal of calculus is extremely important to maintain oral hygiene and protect the health of gums and other periodontal tissues. Since calculus is firmly adhered to the tooth surface, it must be removed with the help of medical equipment. The ultrasonic scaler is commonly used in oral clinics to remove calculus, which is clinically referred to as “oral scaling”, mainly to prevent and stop the development of periodontal disease and treatment, focusing on the removal of calculus from the neck of the teeth, above and below the gingival margin, rather than simply cleaning the teeth to make them change. It is not simply a method of cleaning teeth to make them white or treating gingivitis and bad breath. In addition, frequent smokers or tea drinkers often deposit dark brown pigments and smoke spots on their teeth, which are caused by the wear and tear of the tooth surface, or by the corrosion of acidic beverages and foods that do not smooth the tooth surface. People with more calculus are more likely to deposit pigments. These pigments are different from the calculus in the neck of the teeth and have no obvious pathological significance, but affect the aesthetics, especially on the labial surface of the front teeth. Since the working tip of the ultrasonic scaler is relatively small, it cannot remove the discoloration evenly. It needs to be combined with sandblasting rinsing to effectively remove the discoloration and restore the color and luster of the teeth to achieve a cosmetic effect. This is the “sandblast scaling” for the aesthetics of the teeth. The formation of calculus is related to the oral environment, such as the amount and viscosity of saliva, oral hygiene habits, dietary habits, the body’s endocrine and other factors, just like the scale deposited in the kettle, generally speaking, it is not easy to prevent, of course, eat less soft and sticky food, eat more vegetables and fruits and other fiber-rich food, and develop good oral hygiene habits, to a certain extent, can reduce or delay the deposition of calculus. With the increase of age, the surface of teeth may deposit some calculus more or less. In the early stage of calculus deposition, there are no conscious symptoms when it does not cause gingivitis, so it is easy to be ignored. Therefore, if you have the conditions, you should have regular oral health checkups (about half a year) so that you can detect and remove calculus in time to protect the health of periodontal tissues.
