"It's still difficult to say nichrome roast porcelain tooth what questions there are finally now, we need, understand patient install roast the intersection of porcelain and the intersection of assembly and situation at the tooth, use material,etc. could be assessed behind the overall message at that time. " This staff member says, online information still remains to further verify. It is loaded the roast porcelain tooth yesterday of nickel chromium with that the reporter investigated most suitable persons, the ninth prosthodontics of the People's Hospital gate of market still stood in a long queue. In the team is mostly white collar women, there are men too.

" The roast porcelain tooth of small clinic costs 50 yuan for one In the oral cavity clinic of the roadside, the nichrome roast porcelain tooth nearly becomes the only choice. Yesterday, the reporter came to a small-scale dental clinic in this city, after hearing a reporter plans to install the roast porcelain tooth, the offering price of a staff member: "Original price is 660 yuan, we have favourable activities recently, give a discount the last one only needs 561 yuan. " The reporter questions: "What material is this to make? " "The most ordinary material, a lot of people use this material. " This staff member reveals finally, the roast porcelain tooth material of one of 561 yuan is the nichrome. "Is this kind of material safe? " The reporter asks. "Certainly safe, the people coming here have nearly all installed such roast porcelain tooth, quality rest assured, ensure all the life, use out of question decades. " This staff member explains. According to the introduction of insider, some illegal medical organizations type " 150 yuan for one of roast porcelain tooth " Signboard,it is that some lane little command at clinic price getting lower to 50 yuan every one even, it is not up to standard that the roast porcelain tooth of this kind of low price is not merely made, it is inferior to even bake the metal that the porcelain uses while precededding. The false tooth is processed to lower cost, some large drugmaker personages of hidden danger to reveal, the metal material quality of making the roast porcelain tooth at present is different, it is mainly a few false teeth to make the centre and process links to go wrong. As to roast the intersection of porcelain and source of tooth, one large-scale false tooth process, say such procedure by some director: The doctor does a model according to the patient's teeth, then send to the processing factory of false tooth and process. Because of making the metal of the roast porcelain tooth at present Material quality different, a few false tooth it makes centres or medical organizations to be safe consciousness thin or idea knowledge outmoded, in order to reduce?

The potential safety hazard is very great. Besides this, the patient's consciousness is not strong. A large-scale expert of stomatology department of hospital verifies, " generally all doctors leave and process only, then set up for the patient " . Moreover, " almost all the patients will not ask for the certificate of competency of the products, will not care about the question of the raw materials either " . Do not have conclusive evidence that prove to study the current situation abroad the nickel chromium roast porcelain tooth will cause a disease yesterday definitely, the reporter consults some foreign scholars' research thesis, find that much about study on respect influence such as the oral hygiene, health of roast porcelain tooth of nickel chromium, but point out and it is sure to cause a certain human disease to install the nickel chromium roast porcelain tooth clearly. A pathologic report delivered in May of 1985 is very noticeable, before the rank in the valley song was searched for of this pathologic report depended on very much too. The report is by expert of University of California Los Angeles medical college of branch school Dr. G Strauss in Franklin and the expert of institute's dentistry of oral cavity of University of Southern California David W each A doctor in Sri Lankan writes together, publishes on " American nephropathy magazine ". Say, they have found a disease: A woman patient is behind installing the nichrome roast porcelain tooth, symptoms such as the urine occult blood, urine albumen,etc. have appeared, symptom is relaxed to some extent behind excising the roast porcelain tooth. However, the report points out, this case is only " possible " An example of irritation and nephropathy caused by nickel, it is also not enough to make judgement, need further studying. Some university oral cavity of Sweden corrects researchers RonnyFors and MauritsPersson to once test, alloy tooth correct device and the intersection of installation and the intersection of nickel and tooth correct two groups of contrasts of person of device through install nickel, and reject through factors such as food intake nickel element,etc., the conclusion must happen finally: Nickel metal will be released on surface of tooth and saliva, the quantity released is different as time passes, nickel on the surface of tooth will increase. Publish in a thesis at " whether U.S.A. oral cavity correct and reshape and study the magazine the jaw " showing too, in the intersection of nickel and the intersection of alloy and the intersection of tooth and 2 months correct the device, of installing, nickel content in the urine rises notably. Experiment personnel have gathered the urine sample in front and at the back of installing the tooth of alloy of nickel and correcting the device of 21 patients. Found finally, 2 months after installing the tooth of alloy of nickel and correcting the device, nickel content obviously rose in the urine, and men and women all have this phenomenon. However, the thesis points out, mode and long-term influence that nickel releases also need to further follow and study. The domestic expert's view differs Xinhua hospital oral cavity head of the department Jiang LiPing: In view of long-term quality, the intersection of nichrome and roast the intersection of porcelain and really as other roast porcelain tooth of material tooth. In the clinic, the doctor will recommend the patient to try not to use the nichrome roast porcelain tooth. American, Japanese oral cavity expert come to Shanghai and will often mention the nichrome roast porcelain tooth has microelements to ooze out while giving lessons. The personnel engaged in tooth sale of the roast porcelain of a long-term: Have one human skin exposed to test result, indicate one or two people will appear nickel to be irritated after the use once. The intersection of nichrome and roast porcelain tooth material different, some process roast the intersection of porcelain and false tooth of tooth, make some select cheap apt metal beryllium that scrape for use, make in the roast porcelain precededding, bury the hidden danger of the health. The city eats the relevant personage of Bureau of Drugs Supervision: Just like any kind of medicine, medical equipment, the nichrome roast porcelain tooth needs the clinician, manufacturer to follow in an all-round way after going on the market. And there are few similar basic results of study at present. Nine hospitals of oral cavities of market repair the one of head of the department prosperous and strongly: Nickel the intersection of chromium and roast the intersection of porcelain and tooth as other roast porcelain teeth, but never it is said sending to the statement of nephropathy in professional fielded really. It is in oral cavity each is rich in electrolyte environment,the porcelain teeth roast of material in during appear for metal ion, the intersection of nickel and the intersection of chromium and roast the intersection of porcelain and tooth to so, study, reveal nickel the intersection of chromium and roast the intersection of porcelain and content that tooth appear very little too, within the safe range, so is unharmful to human body. Store Europe in, use the intersection of nickel and chromium roast porcelain tooth little really in the world, the intersection of Asia and multi-purpose the intersection of nickel and the intersection of chromium and roast the intersection of porcelain and contrast of tooth, but the key reason for this kind of state is not that the nickel chromium roast porcelain tooth has already caused the serious damage to the human body, but the economic condition determines. Another part of expert: This incident will impel more people to give up using the roast porcelain tooth of lowest priced nichrome. Is there suspicion of commercial speculation among them? It is doubtful. (old li are given)
