“…Another study compared mercury contamination in dentists and dental assistants in Monastir (Tunisia) to a population not exposed occupationally. Similar results were reached since the exposed group had levels of Hg-U below the safe limit and a correlation was found between Hg-U and the number of dental fillings made per week (Chaari et al, 2009).…”

“…In a work developed in Turkey, Hg levels in the urine of the dentists exposed (6.29 ± 3.5 μg L -1 ) were three fold those found in the control group (1.98 ± 0.9 μg L -1 ) (Karahalil, Rahravi, & Ertas, 2005). However, in Tunisia, the group exposed presented Hg-U significantly higher than controls (about 29.1 ± 60.6 and 0.06 ± 0.4 μg L -1 , respectively) (Chaari et al, 2009). The highest levels of contamination among professionals from developing countries suggest an ordinary negligence of these workers regarding to occupational safety.…”

This work evaluated the impact of exposure to mercury on the health of workers comparing dentists and dental assistants exposed to mercury by handling amalgam in a public dental clinic with a reference group which, in private offices, did not make use of the metal in their professional routine. Data collection included mercury levels in urine and air samples determined by cold vapor atomic absorption spectrometry, questionnaires and direct observation. The difference between urine and air samples in both groups was statistically significant while mercury levels in air and urine showed positive associations. Mercury concentration in urine correlated with gender, practice time, and age of workers. Half of those exposed had complaints compatible with mercury contamination. Among the exposed, the most common complaints were cognitive and neurocognitive symptoms. Correlations between symptoms and exposure time and also number of amalgam fillings placed per week were positive. Amalgam handling resulted in environmental and biological contamination by mercury.

“…The absence of an amalgam separator, equipment placed in-line and designed to capture dental amalgam particles from a dental facility wastewater, is a common finding in research on the topic [9,22,38]. A study financed by the American Dental Association estimated that 50% of mercury found in the sewage systems in US cities came from dental offices [7].…”

This study investigated how 14 dentists and five dental assistants dealt with the waste produced in a dental clinic of the public health service in the city of Rio de Janeiro. The method of direct observation associated with information obtained through a self-filling questionnaire and interviews with the participants were used. The findings pointed out the improper disposal of biological and sharps waste as well as those from dental amalgams. Only radiological waste received an appropriate treatment. Most health professionals ignored the law posing risks to the public health, environment and their own health. The lack of knowledge concerning the procedures recommended by health authorities is responsible for most of the negligent actions used in dentistry. Knowledge about the importance of the proper disposal of waste should begin in professional training courses.

The aim of this work was to evaluate the occupational risks of exposure to mercury utilized in dentistry, to which dental auxiliaries from the public health system of the city of Araguaína, Tocantins, Brazil are exposed. The dentistry process from the city health system was rigorously studied based on an assessment, in the DATASUS database, of the number of amalgam restorations conducted in the period from January 2003 to December 2009. In this study, we evaluated the storage conditions of mercury residuals in the public dental offices in the studied municipality. Different barrier solutions for the storage of mercury residuals were studied regarding their efficacy in controlling the emission of mercury vapor in the environment. The solution containing ammonia presented the best time of storage of residuals (19 days at 37 °C), followed by the so lution containing photographic fixative (12 days) and the sodium bicarbonate solution (7 days). Based on these information, a profile of the dental auxiliaries actuating in the public dental offices of the city of Araguaína was characterized according to age, sex, level of exposure to mercury and conducted biosecurity procedures. The study allowed the elaboration of a database regarding handling and discard of amalgam residuals, with the purpose to assist public health policies to modify risk situations to which the professionals and/or their patients are exposed. A biological monitoring program was also carried out using as marker the presence of mercury in urine samples (HgU) from members of the dentistry team of the Araguaína public health system and from students from the Araguaína unit of the health care technical school who actuated as dental auxiliaries in other municipalities of the north region of the state (n=91). For comparison, a group of "not exposed" to mercury was evaluated (n=43), determining their HgU values. The research allowed to conclude that the HgU values from the dentistry team were within the limits set by Regulatory Norm nº 7 by the Brazilian Ministry of Labor (up to 35 µgHg.g-1 CR). Regarding mercury contamination, the average HgU concentration for the "exposed" group (5,61 µgHg.g-1 CR) was approximately 8 times higher when compared to the values from the "not exposed" group (0,65 µgHg.g-1 CR), making evident the need for a professional training and residuals management program, as well as for a more effective actuation in the realization of periodical biological monitoring in the professionals from the dentistry team.
