"Influence so wide a problem of surface, why trust an expert's investigation? Involve the chemical element, why did no chemist participate in? Find the market confused, why not renovate immediately? " Beijing prosperous lawyer, soldier of benevolence, Li, lawyer's office of promise, say he supervise department, trust Chinese the intersection of oral cavity and conclusion that investigation produce medical association make to full of querying to national medicine.
It is reported, on March 18, national medicine supervises the department and convenes the medical expert of oral cavity, " some consumers present the bad reaction behind installing the nickel chromium roast porcelain tooth " Question have a meeting, be lasted Chinese, whether oral cavity medical association lasted chromium porcelain tooth security roast.
March 21, one by name survey report of " domestic main the intersection of oral cavity and medicine study the nichrome of universities and colleges and bake the porcelain and repair the situation investigation " claim, "Chinese the intersection of oral cavity and medical association trust oral cavity repair professional the intersection of committee and the intersection of sea and blue General Board Feng investigate with greater influence 8 the intersection of oral cavity and oral cavity of medical college repair at home The department uses the situation that the nichrome bakes the porcelain and repairs " ,Draw the conclusion: "It is estimated that in these 20~30 years, these 8 units made about 900,000 units of nichrome and baked the porcelain and precededded together. Among them may cause the allergic one to have 5 examples (have allergic symptoms, but not done "anaphylactogen to check and further diagnose clearly, after using other materials instead, allergic symptom disappears) . Have not found the case which cause nephropathy. "
But one this investigate, receive the intersection of benevolence and the intersection of soldier,etc. and 5 strong query of lawyer Li. "According to our knowledge of realistic state and analysis on this survey report, we think this procedure investigating is unreasonable and investigating the course is insufficient, with more careless conclusion, it is difficult to make people believe. "
They think, national Bureau of Drugs Supervision authorizes the Chinese oral cavity medical association to investigate, Chinese oral cavity medical association trusts director Feng HaiLan to investigate again, this investigation is only finished by a stomatology department doctor finally, there are professional limitation and interests relevance, "the roast porcelain tooth incident of nickel chromium is the important problem that thousands upon thousands users and even national masses in the whole country pay close attention to, but the survey of this incident is only entrusted to a person, obviously, do such great investigation within extremely short time, the manpower allocated is far from enough. "
They query " whether the intersection of nickel and the intersection of chromium and roast porcelain tooth cause kidney trouble " still Originally dispute on the educational circles greatly, if wanting to obtain the final conclusion, must need to carry on sufficient and careful investigation and repeated research demonstration. But investigation claim " count, make how much the intersection of example and nichrome bake porcelain, preceded, have sure difficulty together all by virtue of time " ,Then, " since not all have enough time to finish to relevant statistics in 8 trivial hospitals to connect with, and how could finish complicated careful verification of science, study, prove within this limited time, and draw the conclusion with reliable science? "
Meanwhile, they think, only investigate the large-scale stomatological hospital, perhaps can't reflect the whole state in an all-round way, because in view of sample structure, investigate only to several famous stomatological hospitals, to choose either representative sample, can't reflect little dental clinic that the public suspect generally have the intersection of health and hidden danger in an all-round way. Concern national people's healthy investigation as one, the oral cavity that should collect each level of larger quantity at least makes a diagnosis organization's relevant situation is analyzed. "Moreover, because much the intersection of nickel chromium and roast the intersection of porcelain and the intersection of tooth and the intersection of user and disease send and hold the tooth after for a long time, generally speaking, even the bad reaction appears, the user will hardly link the disease to roast porcelain tooth, certainly will not basically report the condition to medical college of oral cavity and seek help voluntarily. So, only investigate the case which the organization grasps that the oral cavity makes a diagnosis, can not draw the appropriate conclusion, it is a link that should not be omitted either to carry on special visit and follow-up investigation to the roast porcelain tooth user of those representative nickel chromium. "
To the above questions, they call upon Chinese Health Ministry to order medicines to supervise the department to organize real science, rigorous investigation to the roast porcelain tooth question of nickel chromium. They propose, first, set up one in timing supervises department members by the medicine, medical expert, toxicologic expert, investigation group which the dermatosis expert, expert, roast porcelain tooth user of kidney trouble make up together of oral cavity, carry on throughgoing and painstaking investigations to the roast porcelain tooth user in the whole country again, visit the relation between roast porcelain tooth of clear nickel chromium and health. Second, make a diagnosis to roast porcelain tooth manufacturer and every oral cavity strictly in accordance with the law the organization supervises and inspects, and the mechanism of the condition is dealt with in accordance with the law to not reaching the requirement of laws and regulations. Third, announce the method, progress and result to investigate and check to the society in time, and release the behavioral guide of the roast porcelain tooth user of nickel chromium in view of the above.
Li RenBing lawyer think, cause a disease, hang doubt, solve in the course in the intersection of nickel and the intersection of chromium and roast the intersection of porcelain and tooth, many media's investigations find, this field is very confused on the domestic market at present, some bad trade companies produce the roast porcelain tooth not up to standard for saving cost, but some evil mind medical organizations order the use roast porcelain tooth not up to standard, all these had pathogenic risks, national medicine supervised the department since knew this situation, clear up and rectify on should unite other departments in time ing.
