“…composites and amalgams as well as materials used for drilling and polishing. Van Landuyt et al (2014) indicated that such increase of metallic element concentrations is related to significant amounts of particles released into the airborne phase during various mechanical treatments of dental materials which contain these elements. The increased concentration of elements may also be attributed to dental enamel treatment and the use of polishing or prophylactic paste (Sen et al, 2002).…”

“…They also demonstrated a significant elevation of certain trace elements in the generated particles. Van Landuyt et al (2014) indicated that high concentrations of nanoparticles ( 4 10 6 pt/cm 3 ) are released during abrasive procedures such as shaping, finishing or removing composite restorations. The conducted elemental analysis confirmed that airborne particles originate from these composites.…”

“…Dental procedures that involves with those composites could generate nanoparticles with a median size between 38 and 69 nm. [15] Associated health symptoms and diseases with prolonged exposure to PM include increased respiratory disease (i.e., decreased lung function, chronic bronchitis, and premature death due to respiratory problems). [16] The objective of this study was to determine VOC and PM 10 levels associated with activities in a Taiwanese dental clinic and, further, to identify specific VOCs for examining potential health risks to the dental personnel in the dental clinic.…”

This study was conducted to assess (1) levels of volatile organic compounds (VOCs) and particulate matter (PM) in a dental clinic in southern Taiwan and (2) dental care personnel's health risks associated with due to chronic exposure to VOCs. An automatic, continuous sampling system and a multi-gas monitor were employed to quantify the air pollutants, along with environmental comfort factors, including temperature, CO2, and relative humidity at six sampling sites in the clinic over eight days. Specific VOC compounds were identified and their concentrations were quantified. Both non-carcinogenic and carcinogenic VOC compounds were assessed based on the US Environmental Protection Agency's Principles of Health Risk Assessment in terms of whether those indoor air pollutants increased health risks for the full-time dental care professionals at the clinic. Increased levels of VOCs were recorded during business hours and exceeded limits recommended by the Taiwan Environmental Protection Agency. A total of 68 VOC compounds were identified in the study area. Methylene methacrylate (2.8 ppm) and acetone (0.176 ppm) were the only two non-carcinogenic compounds that posed increased risks for human health, yielding hazard indexes of 16.4 and 4.1, respectively. None of the carcinogenic compounds increased cancer risk. All detected PM10 levels ranged from 20 to 150 μg/m(3), which met the Taiwan EPA and international limits. The average PM10 level during business hours was significantly higher than that during non-business hours (P = 0.04). Improved ventilation capacity in the air conditioning system was recommended to reduce VOCs and PM levels.

“…For instance, handling or polishing of dental materials can generate respirable airborne NPs, increasing NP concentration in air from 10 to 45 times [136][137][138]. Exposure limits for these NMs have not been established yet, though as reported by the European Agency for Safety and Health at Work (EU-OSHA), they are expected to be about two orders of magnitude lower than for bulk materials [139].…”

Nanomaterials release quantification and characterization is crucial for risk assessment studies, and experimental simulation studies provide the most concrete basis for estimating the release of nanomaterials in any stage of its life cycle. Nanomaterials are used in a broad range of applications, in different forms (embedded, as coatings, suspended, etc.) and with different size ranges. With all these variables, the number of scenarios where release of nanomaterials could occur is huge. In this chapter, we aim to review use-phase release scenarios that are usually considered in the literature, as well as the results of such studies and the protocols used for product ageing and for nanomaterial quantification and characterization. Finally, we point out the gaps in nanomaterials release studies and identify future research needs.
