“…A questionnaire used previously in other studies 14,15 was administered to all the participants (n = 121) to investigate socioeconomic variables, possible sources of exposure and health effects, and confounding variables for the evaluation of exposure to the metals. Following the interview, blood samples were taken (n = 119) as the biomarker for exposure to Pb 3 and urine samples as the biomarker for exposure to Hg 4 (n = 109).…”

The objective was to assess the level of exposure to lead and mercury in a population in the Pantanal region in Mato Grosso State, Brazil. Blood lead (PbB) (n = 119) and urinary mercury (HgU) (n = 109) in local residents were measured by atomic absorption spectrometry. Comparison of means and correlations between variables used analysis of variance (ANOVA) and linear regression, respectively, with 95% confidence intervals. Mean PbB was 2.82 ± 1.53µg dL-1. The comparison of PbB stratified by collection site (p ≤ 0.01), work activity (p ≤ 0.01), and consumption of locally produced cow's milk (p ≤ 0.05) showed statistically significant differences. There were also positive associations between PbB and collection site (p ≤ 0.01), participants' profession (p ≤ 0.05), local milk (p ≤ 0.01), and source of drinking water (p ≤ 0.01). Mean HgU was 1.41 ± 0.98µg L-1. The levels only showed significant differences for participants' profession (p ≤ 0.01), and positive associations emerged between HgU and work activity (p ≤ 0.01) and body mass index (p ≤ 0.01). The samples showed low lead and mercury levels, similar to those found in other environmentally exposed populations. Despite these low concentrations, current knowledge on the toxicity of these metals shows that health effects can already be felt at levels that were previously considered safe, thus characterizing a health hazard.

Background: Amalgam fillings were invented and introduced to dentistry in France and England during the 1800s. It has since become one of the most reliable dental filling materials to treat dental caries. Dental amalgam contains approximately 50% elemental mercury, a source of occupational exposure among dental personnel and non-occupational exposure among patients. Objective: This study describes the use of dental amalgam in Makkah region dental clinics as a direct restorative material compared to composite and glass ionomer cement. Methods: This longitudinal retrospective study included 335 dental clinics in Makkah and Jeddah, the two largest cities in the Makkah region, Kingdom of Saudi Arabia. Annual statistical data were obtained from the Directorate of Dentistry, Makkah and Jeddah Health Affairs, Ministry of Health. Data related to the restorative materials used (composite, glass ionomer cement (GIC), and amalgam) were counted for 11 years starting from 2009 to 2019 for Makkah city, and the restorative materials used (composite, GIC, and amalgam) from 2018 to the first quarter of 2021 for Jeddah city. Results: There was a slight increase in the number of amalgam restorations in Makkah from 2009 (37.15%) to 2011 (43.52%), followed by a gradual decrease until 2019 (1.39%). In Jeddah, there was a slight increase in amalgam restorations from 2018 (9.39%) to 2019 (11.03%). However, the use of amalgam restorations reduced sharply in 2020 (3.27%) and in the first quarter of 2021 (3.53%). Conclusion: There is a recognizable decreased trend in amalgam utilization in the Makkah region. Amalgam use is being phased down despite the lack of official regulation on its use.
