mercury toxicity in conservative dentistry

In fact, the TSA cumulative z-curve did not cross the alpha-spending function and the conventional boundaries; moreover, it did not reach the RIS threshold (Figure 5). Methodological quality of trials was also analysed for the purposes of the TSA, and one study was considered as at low risk of bias [24], while the other one included in the analysis was considered as at high risk [32]. conducted a further analysis from the CPSST, in which they found an around 5–10% increase of mercury-associated porphyrins in subjects belonging to the dental amalgam group when compared with children whose caries were filled with composite resin [44]. The authors declare that there are no conflicts of interest regarding the publication of this paper. There are many factors to consider when choosing a dentist in general, but when the decision is whether to choose a conventional or holistic dentist, careful consideration is suggested. The quantitative analysis was conducted only on the unique outcome homogenously reported at least on two trials: urinary mercury concentration in children 5 years after restoration of dental caries with dental amalgam or composite resin. Read More . The evaluation of the risk of bias of the included studies is summarized in Figures 2 and 3. Randomization of children was performed with a stratification following their geographical origin or the school they attended. Dental amalgam is a liquid mercury and metal alloy mixture mainly used in dentistry to fill cavities produced by the treatment of dental caries. Subsequent research showed that the exposure time of these factors also plays a crucial role [2]. B-cells functionality demonstrated no differences between the various time points and the two groups. 2020, Article ID 8857238, 12 pages, 2020., 1Department of Head, Neck and Sense Organs, School of Dentistry, Fondazione Policlinico Universitario A.

M. Sechenov First Moscow State Medical University, Moscow 119146, Russia. The search strategy reported above was designed for MEDLINE PubMed and then adapted to the other three databases. There was then a discussion about how to remove the fillings. A manual search was conducted on European Journal of Oral Sciences, Journal of Oral Pathology and Medicine, British Dental Journal, Clinical Oral Investigations, Gerodontology, Journal of Dental Research, and Dental Materials analysing all available RCTs published between January 1995 and March 2020. Following the new directives of the European Union, which foresee the amalgam ban, the debate on its hypothetical toxicity has started again. Only two articles were eligible for quantitative analysis. Therefore, it seems right to clarify and underline the most updated evidence on the subject as dental amalgam could remain the material of choice for the conservative treatment of enamel and dentin lesions in some categories of patients, such as special patient needs, in which a compliance that is essential for the success of caries treatment with composite resins can be achieved rarely. The same concentrations in red cells, on the contrary, raised in the composite group at the first time point (day 60), while in the amalgam group, they diminished slowly in the first year of observation until reaching the baseline level at the end of the study period.

Such measurements were conducted at the time of prescreening and after randomization into groups. Because of the different appearance of the materials to be evaluated in the trials, participants could not be blinded; for this reason, the reviewers decided to exclude participants’ blindness from the judgment regarding the performance bias. Bottom line: there is no “harmless” level of mercury vapor exposure. Qualitative analysis was carried out about the other data. Instead it’s simply being “phased out” of use in dentistry by legislators in most Westernised countries! The same analytic method as per urinary mercury was also used for the analysis of mercury deposits in hair. This was a 7-year trial starting in January 1997, which enrolled children aged 8–10 years during the recruitment phase. A comprehensive systematic literature search was performed in four databases (Ovid via PubMed, Web of Science, Scopus, and CENTRAL) by two calibrated examiners (FG and AC). Social-behavioural effects were evaluated as secondary outcomes. Yet mercury toxicity from dental amalgams is still not recognised as a factor in chronic health conditions within the established medical community. Mercury is a dangerous heavy metal found in old amalgam fillings along with many of the foods we eat. The increase of mercury concentrations in breast milk, umbilical cord, and amniotic fluid was found to be statistically significant in the majority of publication reports about this topic [45–49], whereas controversial results have been published regarding the hypothetical influence of dental amalgam on the onset of mental disorders (mainly Parkinson and Alzheimer disease) [50–52] and of lichen planus and associated lesions [53–55]. A wide variety of symptoms is attributed to toxicity resulting from mercury amalgam.  |  Even though the mercury is still doing systemic, physiological damage, the patient may not be showing signs or symptoms. The shortcomings mostly concerned domains 3, 4, and 5 (blinding of personnel, outcome assessors, and incomplete outcome data) because of the lack of information regarding the blinding of medical and laboratory staff and the high rate of dropouts. Background and Purpose. The authors declared a significant dropout rate since 55 patients did not complete the study through the first 5 years, and additional 96 were lost in the last two years. Romeo Patini and Gianrico Spagnuolo share co-first authorship. Patients were thereby excluded if they reported any type of physical illness or mental disorder. Trials having at least three domains assessed at high or unclear risk of bias were defined as at high risk, and trials with less than three domains assessed at high or unclear risk of bias were considered as having low risk. Numerous studies have reported neurobehavioural effects in dental personnel occupationally exposed to chronic low levels of mercury (Hg). 2004 Oct;81(2):354-63. doi: 10.1093/toxsci/kfh220. Mercury Toxicity of Dental Amalgam. Conclusions. Rev Saude Publica. No statistically significant differences were detected regarding urinary mercury. Composite resins are a material, which guarantee a much better aesthetic result than dental amalgam. cognitive functions; dental personnel; mercury; mood and symptoms; motor functions. The enrolment phase took place between April 1998 and July 2002. 2. Title and abstract analysis led to the elimination of 2293 articles, so 15 results were selected for full-text analysis. In 1960, Keys [1] identified a triad of factors involved in the aetiology and pathogenesis of the disease: a specific bacterial flora, some predisposing factors of the host, and a diet rich in fermentable carbohydrates. These requirements can be easily achieved with the use of the rubber dam, but this tool requires patient compliance, which, in uncooperative patients, cannot be achieved. The meta-analysis was conducted with a fixed-effects model comparing mean differences and standard deviations in case of continuous data. Anyway, all the scores of the amalgam group increased more than the ones of the resin composite group. [Mercury exposure and dentists' health status in two regions of centrall Morocco: descriptive cross-sectional survey]. ““EU mercury regulation implementation tracker,” 2020, R. Patini, E. Staderini, and P. Gallenzi, “Multidisciplinary surgical management of Cowden syndrome: report of a case,”. Randomization of patients was performed stratifying them according to the total number of tooth surfaces filled with amalgam (1–12, 13–18, and 19–25 surfaces) within each group. Unfortunately, Mercury toxicity can cause significant problems in any tissue that gets in its way. Anyway, starting from the first year of experimentation, mercury urinary levels were found to be significantly higher in the amalgam group ( < 0.001). Mercury is a type of toxic metal that comes in different forms within the environment. Mercury Toxicity. Literally amalgam means “mixed with mercury,” and in dental terms, this is true because the composition of the ones used in fillings is formed by 50% Mercury (Hg) and other metals as silver, copper, zinc and tin, that when mixed it hardens in a few minutes at room temperature. Review Manager (RevMan) software was used for the assessment of heterogeneity of the studies included in the meta-analysis [20]. Statistically significant higher rate of NSSs was found in the composite resin group at the second time point. However, if you have symptoms which may be mercury-related, then you should get your fillings changed by a dentist specialising in mercury-free dentistry. Mercury is a highly toxic heavy metal and the mental, physical and emotional effects of mercury on the body have been well documented and known for centuries. The main areas analysed by the checklist were: competence, internalizing behaviour problems, externalizing behaviour problems, and total problem behaviours. In the 18th and 19th centuries, hatters would use mercury compounds in order to manufacture felt. Hg exposure from dental work may also induce various chronic conditions such as elevation of amyloid protein expression, deterioration of microtubules and increase or inhibition of transmitter release at motor nerve terminal endings. NLM In case of a not-negligible heterogeneity (>50%) among studies, a random-effects model was used. Mercury in dental amalgams is released in the form of vapor and can be inhaled and absorbed by the lungs. In 2006, DeRouen et al. Jonidi Jafari A, Esrafili A, Moradi Y, Mahmoudi N. J Environ Health Sci Eng. GRADE summary of findings for meta-analysis on urinary mercury concentration after 5 years of exposure to dental amalgam or composite resin in children. [Mercury and health in the dental practice]. Diverticulosis, stomach cramps, bloating, loss of appetite, and gastrointestinal disturbances. Once in solution, mercury salts are more easily converted by bacterial and fungal metabolic process to the highly hazardous natural kinds of mercury, such as methyl mercury; plus, mercury salts themselves can be about 1000 times more toxic than metallic mercury. The evaluation of the methodological quality of the included studies was performed through the use of the Cochrane Collaboration’s tool for assessing risk of bias in randomised trials. reported data belonging to the two areas [24]. 2019 Mar 5;11(3):147. doi: 10.3390/toxins11030147. This list includes but is not limited to: Headache, fatigue, loss of concentration, irritability, depression, insomnia, and dizziness. For children belonging to the CPSST, the urinary mercury analyses were performed with continuous cold-flow, cold-vapour atomic spectrofluorometry and a PSA Merlin mercury analysis (Questron Corp, Mercerville, NJ) [32, 34]. Therefore, clinical studies of Hg toxicity in dentistry may provide new knowledge about disturbed metal homeostasis in neurodegenerative diseases such as Alzheimer's disease, multiple sclerosis and mood disorders. The excretion of urinary mercury from dental personnel. In light of this, it is crucial to note that a recent systematic review that analysed studies published from 1996 to 2003 asserts that there is no evidence between amalgam and health problems [16]. In 2008, another research group published data about the psychosocial status of children enrolled in the NECAT [35]. Dent. Such checklist was administered to a parent at baseline prior to dental treatment and 5 years later, at the completion of the trial. 2020 Oct 8;18(2):1655-1669. doi: 10.1007/s40201-020-00558-w. eCollection 2020 Dec. Attiya N, Fattahi R, El-Haidani A, Lahrach N, Amarouch MY, Filali-Zegzouti Y. Pan Afr Med J. Studies indicate that chronic exposure to mercury, even at low levels, can cause the following: Cardiovascular conditions. Cohen’s kappa value for global interreviewer agreement was excellent, being 0.82 ± 0.12. Trial sequential analysis for urinary mercury concentration after 5 years of exposure to dental amalgam or composite resin in children. Even if the meta-analysis has drawn conclusions from RCT that should be considered as the best evidence in scientific literature, data regarding the level of urinary mercury in children after 5 years of restoring dental caries with dental amalgam or composite resin were considered to have only moderate strength of evidence because of the high heterogeneity among studies and the presence of one study assessed as having high risk of bias. Your Biological Dentist in Lincoln, NE explains… Again, it is important to note that because mercury is a cumulative toxin, it is quite possible for a patient to have a mouthful of “silver fillings” and not be symptomatic. Make an appointment with Dr. James Groeber of Anderson Aesthetic & Family Dentistry today. Sci Total Environ. Rojas M, Guevara H, Rincón R, Rodríguez M, Olivet C. Rev Environ Health. Only little and not significant deviations were observed in organic mercury concentrations of plasma over the whole study period in both groups. in 2006 presented data regarding mercury levels in urine and hair and about three neuropsychological outcomes (WISC-III full-scale IQ, general memory index, and visuomotor composite) in 534 children [24]. The meta-analysis of the two included trials (one assessed as having high risk of bias and the other one as having moderate risk) analysed data of 859 patients and did not find evidence to determine that dental amalgam restorations in children increased the urinary mercury levels after 5 years of observation (mean difference: 0.77 μg/g; 95% CI: −0.21 to 1.75 ( value: 0.12), heterogeneity: Chi2 = 15.47, df = 1 ( value: < 0.0001); I2: 94%) (Figure 4). He found that when he removed the fillings of people who were very ill, many of them recovered from a variety of medical conditions, including rheumatoid arthritis and neurological impairments like Parkinson’s disease and amyotrophic lateral sclerosis (ALS). Sign up here as a reviewer to help fast-track new submissions. eCollection 2020. Each publication investigated and gave results about different aspects of the health of children whose caries were restored using either dental amalgam or mercury-free composite materials. Moreover, it has to be reported that some authors published cases of burning mouth syndrome and orofacial granulomatosis arisen in patients previously treated with dental amalgam [63, 64]. Results. Such intervention can be considered a step forward to line up with the previous “Minamata Convention on Mercury,” an international treaty that aimed at protecting human health environment from emissions and releases of mercury and its compounds [18]. Number of studies according to meta-analysis, P. H. Keyes, “Recent advances in dental research: bacteriology,”, B. H. Clarkson, “Introduction to cariology,”, V. Moraschini, C. K. Fai, R. M. Alto, and G. O. dos Santos, “Amalgam and resin composite longevity of posterior restorations: a systematic review and meta-analysis,”, D. Hurst, “Amalgam or composite fillings—which material lasts longer?”. On the contrary, no differences were detected at subsequent time points (6, 12, or 60 months). Your Dental Amalgams and Mercury Toxicity Symptoms. The studies that present critical issues with regard to amalgam, however, correlate the hypothetical adverse effects to the number of surfaces treated. The WISC-III was administered 3 times: at baseline prior to caries restoration and 3 and 5 years after baseline. Mercury fillings are a mercury hazard. In fact, as demonstrated by Bowers et al. Nine studies were excluded after full-text evaluation; their references are listed in the excluded studies table along with rationale for exclusion (Table 1). Its indisputable advantages in the treatment of very young patients and in those suffering from systemic syndromes that compromise their collaboration make it a material that can still have a fair use in dental clinical practice. in 2008 investigated some neurological parameters in the population that made up the sample of the CPSST [34]. Dental amalgam is a liquid mercury and metal alloy mixture used in dentistry to fill cavities caused by tooth decay. The results of the TSA analysis are presented as a graph with a cumulative z-curve and its relationship with the other curves (trial sequential monitoring boundary, the futility boundary, and the RIS threshold). For this reason, a quantitative analysis was possible only for the data reported homogenously in at least two studies. Among the four main scales of the CBCL, a significant improvement was noted in the amalgam group with respect to the composite group on the domain “Total Problem Behaviour” ( < 0.007), and a weaker but still significant improvement was noted for the amalgam group in the “Internalizing” domain ( < 0.03). COVID-19 is an emerging, rapidly evolving situation. The qualitative analysis of studies included in the present review revealed a general and transversal lack of evidence towards the potential adverse and toxic effects of amalgam; this could have clinical implications in daily dental practice and induce to resize the policies implemented by various states of the EU deliberately against the use of amalgam in dentistry. His views on amalgam toxicity were featured on 60 Minutes and he was later criticized as a dentist, "prospecting for disease" and having only an "aura of science" by Consumer Reports. NIH [Occupational exposure and health effects of metallic mercury among dentists and dental assistants: a preliminary study. The bibliographies of all articles included were consulted with the aim of analysing as many articles as possible. Heyer NJ, Echeverria D, Bittner AC Jr, Farin FM, Garabedian CC, Woods JS. The statistical analyses carried out in the present systematic review demonstrate the absence of sufficient evidence to ban the use of dental amalgam for caries conservative treatments both in adults and in children. A systematic literature search was conducted in four electronic databases (Ovid via PubMed, Web of Science, Scopus, and CENTRAL) including all available randomised controlled trials published in the last 15 years comparing the use of dental amalgam with composite resins in humans with a follow-up period of at least one year. in 2008 [36]. Mercury toxicity is a concern in dentistry because mercury and its chemical compounds are toxic to the kidneys and the central nervous system. The TSA confirmed this evidence revealing that it was due to a lack of statistical power since the required information size (RIS) threshold is not reached. Low-copper amalgam commonly consists of mercury (50%), silver (~22–32%), tin (~14%), zinc (~8%) and other trace metals.. Several materials can be used for filling cavities left by the removal of the infected tissues, but the most used are dental amalgam and composite resins. Two authors (FG and AC) dealt with the screening of the studies independently and in duplicate. Proper handling of mercury will prevent harm to office staff. Trials took place in USA, Portugal, and Germany giving birth to three, two, and one publications, respectively. No language restrictions were applied. On the contrary, concentration of mercury in hair was found to be similar between groups (0.4 μg/g vs. 0.5 μg/g). The mercury contained in the amalgam leaches out as a vapour into your body for the lifetime of the filling. Urinary mercury was measured also in children belonging to the NECAT with the help of an immunochemical nephelometric method from Beckman Coulter (Fullerton, Calif).

This review included six studies. NHSs are considered predictive of damage to specific neural structures; on the other hand, NSSs are rather predictive of central nervous system dysfunctions.

Special designed data extraction forms were used for this purpose. For this reason, the design of longer RCTs for assessing various types of adverse effects linked to the use of dental amalgam is strongly suggested. [33]. Even in the subscales, patients belonging to the amalgam group demonstrated better improvements than the nonamalgam group patients.
