mercury toxicity in conservative dentistry

Mercury Level in Dentists Mercury levels in whole blood were not high in exposed dentists, although it was reported that dentists have almost twice the concentration of mercury in their blood as non-dentists. The search strategy reported above was designed for MEDLINE PubMed and then adapted to the other three databases. The results of the meta-analysis were expressed using a random-effects model, and their power was assessed through the trial sequential analysis (TSA). 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). 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.

The authors decided to conduct the systematic review by including only RCTs since they are considered as having high strength of evidence. No statistically significant differences were found in any outcome. Dental caries is a progressive disease affecting the hard tissues of the tooth that originates from its surface and that could proceed until involving the dental pulp with an inflammatory process. This was a 7-year trial starting in January 1997, which enrolled children aged 8–10 years during the recruitment phase. Such checklist was administered to a parent at baseline prior to dental treatment and 5 years later, at the completion of the trial. 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. reported data belonging to the two areas [24]. With the aim of highlighting any relationship between dental amalgam and neurotoxicity and nephrotoxicity, the authors defined as primary outcome the Hg concentration in various biological fluids (urine, hair, blood, and saliva).

One of the most investigated topics was antibiotic resistance. Please enable it to take advantage of the complete set of features! This list includes but is not limited to: Headache, fatigue, loss of concentration, irritability, depression, insomnia, and dizziness. 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). Children were included if they had no previous amalgam restorations, if they had at least two dental caries, both located in posterior teeth including occlusal surfaces, and in absence of physician-diagnosed psychological, behavioural, neurological, immunosuppressive, or renal disease. 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. 2020 Jun 19;36:110. doi: 10.11604/pamj.2020.36.110.19623. 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. Two publications reported data gathered from the CPSST. Chronic low-level mercury exposure, BDNF polymorphism, and associations with self-reported symptoms and mood. 2 . Following the new directives of the European Union, which foresee the amalgam ban, the debate on its hypothetical toxicity has started again. 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). Cohen’s kappa value for global interreviewer agreement was excellent, being 0.82 ± 0.12. Background and Purpose. So all data of the single trials were entered into the TSA software; the alpha error was set at 0.05 and the beta error at 20%. 1. 2020, Article ID 8857238, 12 pages, 2020. https://doi.org/10.1155/2020/8857238, 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 analysis of NHSs and positional tremor revealed differences between the groups and among the years, but they never reached statistical significance; furthermore, not even the trend of modifications seemed to be consistent since higher NHSs rate in the amalgam group was seen only in the 1st, 2nd, 4th, and 6th year time points. (7) L.Kantor et al,"Mercury vapor in the dental office-does carpeting make a difference? Since only values regarding the urinary levels of mercury were homogenously reported in publications showing data from NECAT and CPSST, the authors decided to carry out a quantitative analysis only regarding that data. Keywords: Anyway, starting from the first year of experimentation, mercury urinary levels were found to be significantly higher in the amalgam group ( < 0.001). mercury. Randomization of children was performed with a stratification following their geographical origin or the school they attended. In the 18th and 19th centuries, hatters would use mercury compounds in order to manufacture felt. Mercury is a dangerous heavy metal found in old amalgam fillings along with many of the foods we eat. 2019 Mar 5;11(3):147. doi: 10.3390/toxins11030147. eCollection 2020. To prevent mercury exposure, talk to a holistic, mercury-safe dentist like Dr. Boyajian who is a specialist in mercury filling removal. Mercury forms various compounds, well known for their toxicity … 2. Mercury Toxicity of Dental Amalgam. This inorganic form has similar propertie… The WISC-III was administered 3 times: at baseline prior to caries restoration and 3 and 5 years after baseline. After careful evaluation of all the selected full-text, only six RCT were included in this review. © 2018 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society). 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. Despite these very conflicting opinions, in July 2018, the European Union (EU) started a global expiring one year policy for reducing the use of amalgam for dental treatment of children under 15 years and of pregnant or breastfeeding women unless deemed strictly necessary by the dental practitioner on the ground of specific medical needs of the patient [17]. This review included six studies. Statistically significant higher rate of NSSs was found in the composite resin group at the second time point. Bellinger et al. 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. The level of urinary mercury was measured five years after the enrolment; the authors found that patients belonging to the amalgam group had a significantly higher level than children whose caries were restored with composite resin (0.9 μg/g vs. 0.6 μg/g;  < 0.001). MERCURY HAZARDS AND TOXICITY Under the guidance of : Dept of conservative dentistry and endodontics NORTH BENGAL DENTAL COLLEGE AND HOSPITAL. Since RCTs are the studies that give the strongest scientific evidence, the authors decided to include all available RCTs published between January 1995 and March 2020, conducted on adults or children comparing the use of dental amalgam with composite resins. Results. In 1996, a Colorado state judge recommended that Huggins's dental license be revoked, for tricking chronically ill patients into thinking that the true cause of their illness was mercury. Also neurological and social-behavioural effects were evaluated as secondary outcomes. Even if the result of the meta-analysis was found not to be significant, the adjunctive TSA revealed that such nonsignificance was not due to a hypothetical equivalency between the two interventions but rather to a lack of statistical power. The meta-analysis results underwent an adjunctive analysis with the aim of correcting them for the presence of alpha and beta errors and assessing the power of the analysis; for this scope, the authors used the trial sequential analysis (TSA) software (version 0.9 beta, http://www.ctu.dk/tsa). There was then a discussion about how to remove the fillings. Our Nashville practice offers mercury-free fillings at the Centre for Holistic and Biological Dentistry. Elemental mercury (Hg) is found in liquid form, which easily vaporizes at room temperature and is well absorbed (80%) through inhalation. 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. Indeed, most of the evidence supporting the thesis of a link between oral mucosal reactions and dental amalgam are based on case reports [56–62]. 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. 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). Additional urine samples were collected in day 180 from patients belonging to group A. Mercury concentration was determined through cold vapour atomic absorption spectrometry with a gold trap (Hg-Mess-2–87, Leunawerke, Leuna, Germany). The publications investigated eventual nephrotoxicity or neurotoxicity of dental amalgam restorations in children. Mercury poisoning (also Known as hydrargyria or me- rcurialism) is a disease caused By exposure to mercury or its Compound .mercury (Hg) is a Heavy metal occurring in several forms, All of which can produce toxic effects in High enough doses The most significant danger is from mercury vapor. Sci Total Environ. All available randomized controlled trials (RCT) published from January 1995 to March 2020 conducted on humans were selected. Even in the subscales, patients belonging to the amalgam group demonstrated better improvements than the nonamalgam group patients. If you are concerned about Mercury Toxicity, Dr. Boyajian is properly trained in mercury filling removal and focuses on safe mercury removal. The main areas analysed by the checklist were: competence, internalizing behaviour problems, externalizing behaviour problems, and total problem behaviours.

The authors designed a detailed protocol following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement [19]. Bottom line: there is no “harmless” level of mercury vapor exposure. The purpose of this MiniReview is to evaluate the evidence of possible relevance between Hg exposure in dentistry and idiopathic disturbances in motor functions, cognitive skills and affective reactions, as well as dose-response relationships. Today we know that the amalgam mercury filling gives off mercury constantly, making it perhaps the greatest personal source of mercury and most hazardous product ever used in dentistry or in health care. In recent years, however, the use of dental amalgam has decreased considerably as some scientific evidence has revealed that amalgam vapours can be released during chewing and penetrate the systemic circulation by raising blood Hg levels above the threshold values [7]; other studies have correlated urinary Hg concentrations with possible nephrotoxicity and immune system pathologies [8–10]; more recent evidence, moreover, has focused on the hypothesis of neurotoxicity linked to the use of dental amalgam [11] or to the possibility of generating bacterial resistance to Hg and that these resistances can then transmit to other subjects through the exchange of oral fluids [12–15]. Bjørklund G, Crisponi G, Nurchi VM, Cappai R, Buha Djordjevic A, Aaseth J. Molecules. 2004 Oct;81(2):354-63. doi: 10.1093/toxsci/kfh220. Numerous studies have reported neurobehavioural effects in dental personnel occupationally exposed to chronic low levels of mercury (Hg). 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. Search strategy comprehended a combination of free text words and MeSH terms reported as follows: (“dental amalgam”[Title/Abstract/MeSH]) AND (“gingival crevicular fluid” OR “health status” OR “mercury” OR “mercury poisoning” OR “lichen planus” OR “lichenoid eruptions” OR “mouth diseases” OR “mouth mucosa” OR “wound healing” OR “xerostomia” OR “corrosion” OR “craniomandibular disorders” OR “patient satisfaction” OR “hypersensitivity”[Title/Abstract/MeSH]). The same analytic method as per urinary mercury was also used for the analysis of mercury deposits in hair. Analyses were carried out at baseline (patients enrolment), 7 days, and 6, 12, and 60 months after the enrolment [36]. Dental amalgams were first documented in a Tang Dynasty medical text written by Su Gong (苏恭) in 659, and appeared in Germany in 1528. cognitive functions; dental personnel; mercury; mood and symptoms; motor functions. 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]. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Six studies were included in the review (Figure 1). Nine studies were excluded after full-text evaluation; their references are listed in the excluded studies table along with rationale for exclusion (Table 1). Observational studies conducted on adult populations mainly focused on three big areas: mental disorders, hypersensitivity, and lichenoid lesions and perinatal medicine. Epub 2003 Apr 4. 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. Risk of bias graph with overall percentages of bias for each domain. We are committed to sharing findings related to COVID-19 as quickly as possible. 2003 Apr;37(2):266-72. doi: 10.1590/s0034-89102003000200018. To ensure safe and sustainable outcomes in any dental procedure, it is a good idea to select a dentist who offers mercury safe dental treatments in Anderson SC. In both plasma and red cells, the levels of inorganic mercury showed a very similar trend: in the composite group, the levels decreased until reaching a steady-state (around day 60), while in the amalgam group, they remained constant. No additional publications were found through the manual search or in the bibliographies of the included studies. Mercury poisoning symptoms can arise from dental amalgam mercury fillings, also called silver fillings, as they continuously release mercury vapor. 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. 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]. 1986 Jan-Dec;6(1-4):297-309. doi: 10.1515/reveh.1986.6.1-4.297.

Difference between groups was around 1.5 μg/g in the first 3 years of follow-up, and then, it declined to around 1.0 μg/g in the subsequent years. 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. A fluctuation of lymphocytes, monocytes, and neutrophils was observed but without statistically significant differences. Total WBC enumeration and distribution of immune cells were performed through the haemocytometer and flow cytometer. The authors stated a significant dropout rate during the study. The unit of measures were the same reported in CPSST. Risk of bias summary across all included studies. An author supervisor (RP) was consulted in case of disagreement. All trials had a parallel group design, except for Halbach et al. WBC, T-cell, B-cell, and neutrophil and monocyte responsiveness, Quality assessment and outcome: urinary mercury levels after 5 years of exposure to dental amalgam or composite resin in children. Three publications, among the six included in the present review, presented the results of a RCT known as NECAT and conducted between September 1997 and March 2005 in five community health dental clinics in Boston (Mass) and one in Farmington (Me). So, observational studies have been conducted with the aim of investigating the possible association between dental amalgam and the developing of antibiotic resistance in oral cavity bacteria. The NHSs and NSSs analyses were performed by two neurologists once a year for 7 years starting from the baseline for NHSs and starting from year 2 for NSSs. Keywords:Mercury toxicity, Dental amalgam, adverse effect, Hazardous waste Introduction Mercury combines readily with other metals to form solid amalgams, which have been used continuously in dentistry for nearly 200 years to reconstruct decayed teeth. An adjunctive analysis was performed independently by two reviewers (FG and AC) regarding the overall quality of evidence at the outcome level using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) system. 1990 May 15;94(3):179-85. doi: 10.1016/0048-9697(90)90169-u. Clinical Effects of Mercury in Conservative Dentistry: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Controlled Trials Romeo Patini , 1 Gianrico Spagnuolo , 2 , 3 Federica Guglielmi , 1 Edoardo Staderini , 1 Michele Simeone , 2 Andrea Camodeca , 1 and Patrizia Gallenzi 1 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. Another limitation of the present review has to be pointed out: even if generally RCTs are considered “gold standard” for clinical research, they may not be long enough to assess the long-term effect of an intervention such as detection of long-term adverse effects after chronic exposure. We follow biological dentistry principles, offering general, cosmetic, and mercury-free dentistry.The latest techniques and technologies, personalized care, and a comfortable and environmentally responsible practice are our hallmarks. in 2008 [36]. NIH In NECAT also the social-behavioural outcomes contained into the Child Behaviour Checklist (CBCL) were analysed [39]. In the article by Shenker et al., reporting analysis of data gathered from a subgroup of children enrolled in the NECAT, immunological parameters were evaluated: white blood cell enumeration, assessment of T- and B-cell responsiveness, and analysis of neutrophil and monocyte responsiveness. Where can I find a dentist trained in these techniques? The Wide Range Assessment of Visual Motor Ability and the Wide Range Assessment of Memory and Learning were administered twice: at the baseline and after 4 years. Five studies enrolled a population of children (between 6 and 12 years), whereas only one enrolled adult people (20–50 years). But because mercury toxicity is a cumulative toxicity and as such, can store itself in many tissues of the body for years, it is possible that your fillings may be the cause of chronic maladies that have affected you for years. To prevent additional mercury exposure, patients should inquire about the amalgam removal protocols: IAOMT Protocols for Mercury Filling Removal. Special designed data extraction forms were used for this purpose. For this reason, a quantitative analysis was possible only for the data reported homogenously in at least two studies. 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. However, in the literature, there are numerous observational studies and case reports that detected a high amount of side effects related to the use of dental amalgam. Title and abstract analysis led to the elimination of 2293 articles, so 15 results were selected for full-text analysis. Final Thoughts on Mercury Toxicity. 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. Publications showing data from the NECAT presented also data on full-scale IQ (according to the Wechsler Intelligence Scale for Children, Third Edition, WISC-III), on visuomotor ability assessment index and the general memory index (gathered from the Wide Range Assessment of Visual Motor Ability and from the Wide Range Assessment of Memory and Learning, respectively). Even though the mercury is still doing systemic, physiological damage, the patient may not be showing signs or symptoms. Tremor was recorded apart since it is one of the most frequent manifestations of mercury toxicity. What Are the Symptoms of Mercury Toxicity?  |  [33]. Conclusions. The methodological quality of the included studies was moderate for one study [24] and low for the other 5 studies [32–36]. Dental amalgams are 50% mercury. 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].
