Quantitative and qualitative analysis of operator inhaled aerosols during routine motorised equine dental treatment.

Abstract: Routine equine odontoplasty is performed by both Veterinary Surgeons and Equine Dental Technicians. The production of aerosolised particulates from motorised equipment has been well documented in human orthodontics but has yet to be investigated in the veterinary industry. Objective: To assess the size, quantity and composition of particulates produced during routine motorised odontoplasty and to model their deposition in the human respiratory tree. Methods: Analytic observational study. Methods: Fifteen-minute routine motorised odontoplasties were performed on cadaver heads with monitoring equipment placed 30 cm away from the oral cavity to simulate the position of the operator's face. For quantitative analysis, an active air sampling photometric monitor was used to detect the concentration of fully respirable (<4.25 µm) particles produced. The use of water and non-water-cooled equipment and 2 different types of face mask (standard surgical and FFP3) were compared. An 8-stage Marple Personal Cascade Impactor modelled the deposition of the particulates in relation to the human respiratory tree. Qualitative analysis of these particulates was performed using scanning electron microscopy and energy dispersive x-ray spectroscopy. Results: Motorised odontoplasty created aerosolised particulates that could reach all levels of the human respiratory tree. These particulates were composed mostly of calcium and phosphate, although traces of metals were found. The concentration of fully respirable particulates exceeded the recommended exposure limits set by the Health and Safety Executive. The use of an FFP-3 face mask significantly reduced the level of inhaled particulates. Conclusions: This was a simulated experiment. It does not take into account the variety of environments in which routine treatment takes place. Conclusions: There are possible health risks in performing a large amount of routine motorised dentistry due to inhalation of aerosolised particulates. The use of an adequate face mask lowers exposure levels to within acceptable limits and, therefore, should be worn.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research study examined the size, quantity, and composition of aerosolized particulates produced during routine equine (horse) dental procedures performed with motorized equipment. They also examined their potential deposition in the human respiratory system. The study revealed that this procedure creates inhalable particles that can reach all areas of the human respiratory system, exposing the surgeon or technician to potential health risks. However, the use of a specific type of face mask, the FFP3, significantly reduced these risks.

Research Methodology

  • The research was carried out using an analytic observational study approach.
  • The experiment mimicked standard 15-minute equine dental treatments performed on horse cadaver heads employing motorized equipment.
  • The recording monitor was placed 30cm away from the horse’s mouth to simulate the position of a human’s face during treatment.
  • To gauge the concentration of fully inhalable particles, an active air sampling photometric monitor was employed. Various equipment configurations were compared, including water and non-water-cooled devices.
  • Two types of face masks, standard surgical and FFP3, were also compared for their effectiveness.
  • An 8-stage Marple Personal Cascade Impactor was used to model deposition of the particles in relation to the human respiratory system.
  • Scanning electron microscopy and energy dispersive x-ray spectroscopy were utilized for a qualitative analysis of the particulates.

Research Findings

  • During horse dental procedures with motorized tools, aerosolized particulates can be created that can reach all areas of the human respiratory system. These mostly contained calcium and phosphate, although traces of metals were also found.
  • The concentration of respirable particulates exceeded the health and safety limits set by the Health and Safety Executive.
  • The FFP3 face mask was more effective at reducing inhaled particulates than the standard surgical mask.

Study Conclusions and Implications

  • The research was conducted under controlled, simulated conditions and does not take into account the variety of real-world environments in which routine treatments take place.
  • This means while its findings provide important insights, they may not perfectly represent actual treatment conditions.
  • Nonetheless, the study establishes potential health risks for those performing routine horse dentistry due to inhalation of aerosolized particulates.
  • It suggests that using an adequate face mask, specifically an FFP3, can lower exposure levels to within acceptable limits and is therefore recommended for those performing these procedures.
