Pregnant women have gingivitis or cause premature fetus

In real life, we can see that the number of pregnant women during pregnancy, some of the common oral diseases, such as: gingivitis, periodontal disease, tooth decay, tooth ache, etc., but these symptoms did not cause the attention of the mothers who, some people even ignore it. In fact, pregnancy oral hygiene is not only related to the health of pregnant women, but also related to the safety of her unborn child.

Pregnant women, estrogen and progesterone levels increased significantly, especially falconoid levels raise very high, make the gums vasodilator, increased vascular permeability, easily lead to swollen gums are likely to cause bleeding gums, which is called as "pregnancy gingivitis." Not to women suffering from gingivitis before pregnancy, the pregnancy rate and dental instruments the extent of the troubles "pregnancy gingivitis" low before pregnancy of women with gingivitis, inflammation will increase after pregnancy, the gums will appear hyperplasia, swelling , bleeding and severe impact of a meal, thus affecting pregnant women's nutrition absorption.

When pregnant women with gingivitis, bacteria can enter the bloodstream through the placenta and infect the fetus, resulting in the premature fetus and premature rupture of membranes. Premature fetuses due to the various systems is not yet mature the survival rate and quality of life significantly less than the full-term children. Premature rupture of membranes not only can induce premature labor, but also occurred to pregnant women to intrauterine infection and good basic nursing care is fundamental umbilical cord prolapsed. The occurrence of these conditions will increase the family burden, so that had a happy birth cast a shadow.

Therefore, during pregnancy, if periodontal disease should be promptly to the regular dental hospital for oral health and oral examination.

Four you abide by the rules to protect the teeth

1. Sour things and sweet things are harmful to the teeth.

Sugar not only will destroy the enemy of dental health, the lower pH of the sour food will soften the teeth, such as acid, sugar, soft drinks, fruit juice. As a result, incurred by the enamel layer of corrosion, smaller teeth. Citric acid is the most harmful to your teeth acid. So, every day you should be concerned with the acid corrosion of the teeth.

2. The enamel is the hardest substance in the body, but easy to break.

Ice, popcorn kernels pierced tongue and lips can cause teeth to rupture. With skin, teeth can not regenerate. Eat popcorn grain like to eat "stone", the ice is sharp and fragile, these foods may damage the tooth enamel, especially his mouth full of things you need to be carefully.

3. Too much fluoride is harmful to the teeth.

We know of fluoride on dental health is very important. But at 8 years old or less than 8 years old, the children's permanent teeth are in the developmental process; this time excessive intake of fluoride will make them suffer from fluorosis disease.

Unfortunately, fluorosis is intrinsic, which means that the dentist can not easily wipe the surface spots. In order to ensure that children do not swallow the toothpaste, parents must tell the children extrusion of toothpaste should not be dental instruments more than one pea size. Most cases of fluorosis and children excessive use of toothpaste.

4. Orthoses can cause tooth decay.

The braces around the food, bacteria and Advanced orthodontic treatment dentition status acid make tooth loss; the result is tooth becomes difficult to see.

In fact, the cavities formed in the appliance bay around. Although the rot does not fully formed cavities, but it can lead to the removal of mineralized, making the teeth appear spot. With the larger cavities of the spot will be black.

Fixed partial denture the patient's oral health care

The rugged, fixed partial denture wear-resistant, beautiful, comfortable, do not need to pick to wear characteristics, is easily accepted by the patients. However, due to health knowledge after the majority of patients with lack of repair, restoration may be secondary to inflammation of the mouth after the remaining teeth and periodontal tissue lesions, an excessive burden on the remaining teeth. So should the knowledge of educational and behavioral guidance, to extend the duration of use of the denture and to achieve the desired results after the repair.

One. Fixed partial denture hygiene instruction

In recent years, natural crude fiber food is dwindling, soft diet gradually increased due to the fixed bridge is a fixed prosthesis in the oral cavity, soft food in the natural surface of the teeth and denture fissure with the formation of soft dirt, hard to dental instruments remove tartar affect oral hygiene, so Zhu Huanzhe eating solid food, or with including fiber-rich foods or regular teeth cleaning.

In addition, we also necessary in the church of the patients after each repair, improve their awareness of oral health care. Maintaining good oral hygiene to ensure the denture wear, periodontal tissue health, to prevent the remaining teeth with caries and extend the duration of use of the denture, fixed prosthesis is always to maintain good function and satisfactory repair effect.

Two. Health care measures

1. Adhere to brush your teeth is an effective way to maintain oral and denture cleaning. Fixed partial dentures can not remove the cleaning brush your teeth to remove tartar and dental calculus deposition, to prevent bad breath and gum from the protection and the role of massage to promote periodontal tissue blood circulation and improve their resistance to diseases and can increase appetite, reduce the mouth as a causal factor.

2. The right choice toothbrush and using the correct method of brushing. The correct brushing method of vertical brush force should be the appropriate action can not be too fast; you can achieve the purpose of massage gums and will not damage the teeth and gums.

3. Mouthwash is a necessary complement to brush your teeth, maintain oral hygiene. As one of the complementary method of brushing teeth, gargle easy and the current rush to massage the gums.

Cobalt-chromium alloy porcelain teeth good?

Porcelain teeth, a dental prosthesis is currently very popular, and it helps a lot of tooth loss in patients with a friend to regain a healthy white teeth. A type of porcelain teeth, cobalt chromium alloy porcelain tooth is one of them.

The most popular method is the treatment of tooth defects porcelain teeth, porcelain teeth, is a relative in the oral long-term retention and difficult saliva corrosion of dental restorations. Will not hurt the teeth, can restore the teeth in the chewing function. Many different types of porcelain teeth, metal porcelain teeth, within the crown porcelain teeth, cobalt chrome, porcelain teeth. According to the comprehensive reference of the costs, effectiveness, security, cobalt chromium alloy porcelain teeth is a very high cost.

The advantages of cobalt chromium alloy porcelain teeth mainly due to:

1. Realistic appearance: the color of the teeth after the treatment and true tooth color, and permanent discoloration, outsiders with real teeth. Does not lead to a class of black gum line.

2. Wide: it is suitable for various are not satisfied with teeth, such as: too loose teeth, broken teeth, missing teeth and so this method to make up.

3. Biocompatibility: does not irritate in the treatment of oral tissues, easy to clean, good biocompatibility, is generally not allergic organization.

4. High intensity: the cobalt-chromium alloy porcelain teeth are semi-precious metal porcelain teeth, high hardness of the cobalt and chromium alloy porcelain teeth. Can have sufficient strength to withstand the force of chewing mouth and dental equipment wear.

5 Affordable: the price is relatively cheaper metal and word porcelain teeth, has been accepted by more and more people.

In addition, the price of cobalt chromium alloy porcelain teeth is relatively modest; but to do the technical and professional requirements of porcelain teeth are Teeth whitening technologies are the technical advantages very high, and should go to a professional formal Dental Clinic. Do not formal diagnosis and treatment institutions for treatment, in order to avoid lay hidden dangers to our security.

Occlusal design of the dental implant rehabilitation program

Difference due to the presence of structural features of the implant denture with natural teeth, implant restoration of the occlusal design should take into account many factors.

Bite design bite force related to the implant size and conduction direction, in principle, be transmitted to the implant restoration bite force on the body control in patients with stomatognathic system able to withstand the physiological limits, and try to avoid the role of the lateral force.

Biomechanical study on bone tissue: to withstand the strongest bone of the axial load, the tension, shear force, poor endurance, reduced to 30%, 60%;

Compressive strength and tensile strength limit of the bone will be reduced as the power angle increases, the compressive strength and tensile strength of 300 of the lateral force can bone decreased by 10% and 25%, 600 decreased by 30% and 55% respectively;

The lateral force on the one hand weaken the mechanical properties of bone tissue, on the other hand, significantly increased the shear stress and tensile stress, a threat to the dental instruments weak integration between the implant and the bone. Using the finite element method for measuring the lateral force can shear stress and tensile stress increased by 10 times.

Occlusal design in terms of the bite force of the size of the implant and Orthodontics to bypass the "myths" to go conduction direction should be done to reduce the axial force and the elimination of lateral forces.

The patient's jaw reconstruction involves the location of the implant and natural teeth implant number, length, angle, diameter, and repair of the way.

Occlusal design principles are: 1. Establish a stable middle of the jaw, the bilateral contact relationship of jaw to establish the maximum tip nest, as far as possible bite force for the axial, reduce the angle of the lateral stress. Two. Mandibular occlusal freedom without deflection to the side and protrusive movement. 3. To establish the middle of the free domain, and the receding contact (RCP) and the cusp intercostals position (ICP) is consistent.

Teeth whitening there are two errors

Misunderstanding one: for whitening harm the teeth.

     

Pursuit of the beautiful appearance of the teeth and bring irreversible damage to the tooth itself can be said that oral health care a top regret. Take the "tetracycline", at this stage, many clinics have also taken to the crown finely ground, then put on the practice of a porcelain crown, the tooth is pretty, but over time will be revealed. Have been okay with finely ground the teeth tend to become sensitive, fragile, porcelain crowns, metal parts are easy to stimulate the gums, so that black gums, shrinking.

Experts recommend the use of 3D white patch. This is the most safe and natural teeth whitening methods. 3D white patch after a few computer simulation, first the tooth surface friction out a thin layer, then use the 3D camera image in the mouth, carved out of teeth worn part is completely consistent with the artificial enamel restorations will this layer of the white patch embedded dental instruments in the original teeth, so that the pure white patch with teeth combined.

Misunderstanding two: dental amalgam and other materials.

Cavities patched with silver amalgam, in fact, such materials have been eliminated in developed countries. Amalgam color pretty, most of the repair, the following dental defect and the posterior region of the amalgam can not be generated with the teeth closely integrated easily lead to secondary caries and intensity shortcomings, heavy metals but also on the body negative impact. More than half or more teeth defect repair worn more natural teeth, making the braces. In recent years, widespread use of ceramic materials is the ceramic powder at high temperatures barbecue, rapid cooling from the drawback is hard and brittle, easy to crack and color, easy to damage the teeth with bite. This is a compressed ceramic powder vacuum firing porcelain material, which after a slow cooling, and NO extraction can quickly correct deformities teeth its density is uniform, not easily cracked, good transparency, and repaired to make the teeth look very natural. After ten years of clinical experience in a foreign country that, up to 98% of the wear degrees and the natural tooth enamel.

White enamel hardness decline

A new study shows that the use of home teeth whitening products make people's enamel hardness decreased. According to the person in charge of the study, said Shereen Azer, assistant professor of prosthodontics, Ohio State University, USA, whitening of teeth, enamel hardness by an average of 1.2 to 2 nanometers. Teeth whitening products contain different concentrations of hydrogen peroxide or car amide peroxide; they produce free radicals that attack the enamel integral part of the pigment molecules, so as to achieve the whitening effect.

Azer said that some research trying to figure out the impact of the teeth whitening products on enamel hardness, but study results are inconclusive. He added that, prior to the micron level, the scholars in the reduced enamel hardness, and he used in the study nonsocial. In the study, he removed teeth whitening paste and bay filled with whitening gum, and use of atomic force microscope to observe the teeth on the nanometer scale. A different product for tooth hardness and dental instruments elastic modulus change is roughly the same. However, single and single-bay there are significant differences reduce the hardness of enamel, single bracket than single-whitening paste whitening paste.

Although the study did not rise the hardness recovery whitening teeth, but Azer noted that the large number of studies has shown that fluoride treatment can promote the re-mineralization of enamel. According to the results of the study, he suggested that the new teeth whitening products in the future there should be improved in an effort to Fixed dentures and denture relative to comparative advantage reduce the occurrence of these side effects. The enamel is the hardest structure of the human body. Teeth whitening products may weaken this natural barrier.

Laser teeth whitening

Laser teeth whitening is a bleaching effect of a higher concentration of bleach (hydrogen peroxide), with an appropriate dose of the laser, such as Nd: YAG laser, catalytic peroxide to increase and accelerate the peroxides and selective the role of the pigment particles deposited on the teeth, the tooth within the organic pigment bleaching their loved ones by the carbon ring structure water-based pigment-free structure.

Tooth structure suction Everbrite molecules break into small molecules, eliminating the absorbance, and safe whitening efficacy.

Appropriate doses of laser irradiation can be closed dentinal tubules, reducing dentin permeability, reducing the symptoms of dentine dental instruments hypersensitivity occurred in the tooth bleaching process.

Reminder:

Condenser results in the laser teeth whitening a large range of radiation, high temperature, a slight mistake on the tooth nerve, the teeth surrounding tissue is likely to cause injuries. Therefore best to choose the more secure the teeth whitening methods.

Mandibular incisor root canal shape: Mandibular Incisors

Narrow and flat in the labial-lingual dimension, the mandibular incisors are the smallest human adult teeth. Visible radio graphically from only one plane, they often appear more accessible than they really are. The narrow lingual crown offers a limited area for access. Smaller fissure burs and no. 2 round burs cause less mutilation of coronal dentition. The access cavity should be ovoid, with attention given to a lingual approach. Frequently the mandibular incisors have two canals. One study reported that 41.4% of mandibular incisors studied had two separate canals, of these, only 1.3% had two separate foramina. The clinician should search for the second canal immediately upon completing the access cavity. Endodontic failures in mandibular incisors usually arise from unlearned canals, most commonly toward the lingual.

Access may be extended incisally when indicated to permit maximum labial lingual freedom. Although labial perforations are common, they may be dental instruments avoided if the clinician remembers that it is nearly impossible to perforate in a lingual direction because of the bur shank's contacting the incisal edge. The ribbon -shaped canal is common enough to be considered normal and demands special attention in cleaning and shaping. Ribbon-shaped canals in narrow hourglass cross-sectional anatomy invite lateral perforation by endodontic files and Several hot spots of the clinical orthodontic correction Gates-Glidden drills. Minimal flaring and dowel space preparation are indicated to ensure against ripping through proximal root walls. Apical curvatures and accessory canals are common in mandibular incisors.

Healthy teeth whitening

There are snow-white teeth, and have smiles on their faces. If the teeth are not white, I'm afraid the laugh is not so natural. Social progress, more and more advanced teeth whitening methods. Teeth whitening, and beautiful to the teeth, it became fashionable men and women to catch up with the trend.

There are snow-white teeth, and have smiles on their faces. If the teeth are not white, I'm afraid the laugh is not so natural. Social progress, more and more advanced teeth whitening methods. Teeth whitening, to a "beautiful teeth", it became fashionable men and women to catch up with the trend.

However, everything has a teeth whitening beauty is nothing wrong, but too much whitening, improper whitening, it may hurt their teeth, and even other organizations of the oral cavity.

Some people's teeth yellow or dark, which is mainly there are two possibilities, one is caused by eating and living habits, like eating some more food pigment, such as betel nut, or smoke, drink coffee, tea, red wine, the pigment will be calm in the teeth, but the dental instruments main surface of the teeth. Another is because the drug effects, pigmentation of teeth within the organization, such as the so-called tetracycline and dental fluorosis.

The experts Reminder: each person to select the appropriate tooth whitening their teeth, do not blindly follow the trend. If your teeth yellow, black, or stubborn tetracycline, dental fluorosis, then it may be pumped empty, to be 360 ° IPL teeth whitening spa, there will be make your surprise whitening effect !

More appropriate when the teeth in the elderly after tooth extraction

Recently for some friends do not understand the elderly extraction when the denture is more appropriate for this tooth dot com invited experts elderly tooth extraction when the denture is more appropriate to talk about.

Many elderly patients want in the shortest possible time after tooth extraction dentures fitted, especially in patients with dental instruments defects in anterior teeth require some teeth feel more urgent. The extraction of the elderly when the dentures most appropriate it?

We know that in the alveolar bone, the tooth was removed leaving a cavity called Socket. In general, the front teeth only one root, the wounds grow faster, about 30-45 days after tooth extraction teeth. Then the teeth due to Teeth whitening health remedies root more so after tooth extraction 60-90 genius is the best time of the teeth. Elderly friend's body will be weak, so the time required may grow a little.

These are on the extraction of the elderly when the denture is more appropriate.
