“…This was done for the gravitometric settling of airborne bacteria. Although splatter aerosols settle very quickly on surfaces the droplet nuclei (<50 µm) remain suspended in air for longer time and can infect person by direct inhalation and penetration deep in lungs [10]. The aerosol peaks decreased to the background levels within 10 and 30 min caused by rapid deposition of particles after aerosol generation at patient head height.…”

Background and Objectives: The purpose of the present study was to determine the microbial atmospheric contamination during initial periodontal treatment using a modern piezoelectric scaler and to evaluate the efficacy of two commercially available mouth rinses (0.2% Chlorhexidine mouth rinse and Listerine) in reducing bacterial contamination when used as a pre-procedural rinse, with and without high volume evacuation (Aerosol reduction device).

“…Certified particulate respirators have been shown to have superior filtering protection compared to high quality surgical masks in the dental setting 36) . If masks are used, face seal masks have been shown to protect against and reduce the exposure to aerosolised microorganisms 37) . The use of personal protective measures is particularly important as it is not always possible to determine HBV or HIV status from a patient's self-reported history and / or clinical examination.…”

Occupational Health Problems in Modern Dentistry: A Review

2007

View full text Add to dashboard Cite

Despite numerous technical advances in recent years, many occupational health problems still persist in modern dentistry. These include percutaneous exposure incidents (PEI); exposure to infectious diseases (including bioaerosols), radiation, dental materials, and noise; musculoskeletal disorders; dermatitis and respiratory disorders; eye injuries; and psychological problems. PEI remain a particular concern, as there is an almost constant risk of exposure to serious infectious agents. Strategies to minimise PEI and their consequences should continue to be employed, including sound infection control practices, continuing education and hepatitis B immunisation. As part of any infection control protocols, dentists should continue to utilise personal protective measures and appropriate sterilisation or other high-level disinfection techniques. Aside from biological hazards, dentists continue to suffer a high prevalence of musculoskeletal disorders (MSD), especially of the back, neck and shoulders. To fully understand the nature of these problems, further studies are needed to identify causative factors and other correlates of MSD. Continuing education and investigation of appropriate interventions to help reduce the prevalence of MSD and contact dermatitis are also needed. For these reasons, it is therefore important that dentists remain constantly informed regarding up-to-date measures on how to deal with newer technologies and dental materials.

“…Besides, how far the spread of aerosol and the level of contamination are still in attention. 11 According to Bennet et al 5 , aerosol peak decreased to the background level within 10 minutes and 30 minutes due to the rapid deposition from particles after the high level of aerosol in the patient's head (about 1 m from the base), particularly with scaling procedure.…”

“…Those instruments are used in patient's oral cavity with various microorganisms derived from saliva, blood, and dental plaque. 5,6,7,8,9 Therefore, the dentists are often exposed to microorganisms that harmful to the health. 10 Mikitka et al 11 said that there is some evidence for greater prevalence of respiratory disease.…”

“…Aerosol contains many microorganisms derived from blood, saliva, debris, dental plaque, calculus, and restorative materials produced by ultrasonic scaler when used with water spray. 5,6,7,11,14 Each of the patients has different aerosol composition depends on the teeth condition in the operative area and the level of microorganisms in patients' oral cavity. 6,13 The use of pre-procedural mouthwash before ultrasonic scaling treatment is one of some methods to reduce aerosol contamination.…”

The Difference of Bacterial Aerosol Quantity Based on Blood Agar Plate Position

2017

Objective: The purpose of this study was to determine the difference of bacterial aerosol quantity based on blood agarplate position with and without using chlorhexidine as pre-procedural mouthwash in ultrasonic scaling treatment. Methods:The 16 samples rinsed using chlorhexidine and other 16 samples rinsed using sterile water before ultrasonic scaling treatment was started. Bacterial aerosol was collected using blood agar plate for 10 minutes during ultrasonic scaling treatment and placed at three different positions: chest of patient (P-I), right side of patient-8 o'clock (P-II), left side of patient-4 o'clock (P-III). Results:The Friedman test result showed that p= 0.223 (group I) and p< 0.001 (group II). The p= 0.223 showed that there was no significant difference of bacterial aerosol quantity based on blood agar plate position. Conclusion:Chlorhexidine can be used on bacterial aerosol reduction during ultrasonic scaling treatment.
