Dissemination of aerosol and splatter during ultrasonic scaling: A pilot study
Journal of infection and public health, 2015Co-Authors: S. Mahantesha, Preethi A. Joseph, Sudhir R. Patil, Suvarna H. PatilAbstract:Summary Context Routine dental procedures produce aerosol and splatter, which pose a potential risk to the clinician and dental personnel, as well as the immunocompromised patient. Reports indicate that the ultrasonic scaler is the greatest producer of aerosol and splatter. Aims The study aimed to evaluate the contamination distance, contamination amount and contamination duration of aerosol produced during ultrasonic scaling. Methods and materials The study was performed on a mannequin fitted with phantom jaws on a dental chair. Mock scaling was done for 15 min using an auto-tuned magnetostrictive ultrasonic scaler with the simultaneous use of a low volume Saliva Ejector. An ultrafiltrate-containing fluorescent dye was used in the reservoir supplying the scaler unit. Filter paper discs were placed in different positions and distances in the operatory. Immediately following scaling, the filter paper discs were replaced with new ones. This was done every 30 min for a total duration of 90 min. Results Maximum contamination was found on the right arm of the operator and left arm of the assistant. Contamination was also found on the head, chest and inner surface of the face mask of the operator and of the assistant. The aerosol was found to remain in the air up to 30 min after scaling. Conclusions The occupational health hazards of dental aerosols can be minimized by following simple, inexpensive precautions.

Comparison of suction device with Saliva Ejector for aerosol and spatter reduction during ultrasonic scaling.
Journal of the American Dental Association (1939), 2014Co-Authors: Jessica L. Holloman, Sally M. Mauriello, Luiz André Freire Pimenta, Roland R. ArnoldAbstract:Abstract Background Aerosols and spatter are concerns in health care owing to their potential adverse health effects. The Isolite illuminated isolation system (Isolite Systems) and a Saliva Ejector were compared for aerosol and spatter reduction during and after ultrasonic scaling. Methods Fifty participants were randomized to control (n = 25, Saliva Ejector) or test (n = 25, Isolite) groups and received a prophylaxis with an ultrasonic scaler. Aerosols were collected in a petri dish containing transport media, dispersed, and plated to anaerobic blood agar to determine colony-forming units (CFUs). The authors analyzed the data using a t test. Results No significant difference occurred between groups in aerosol and spatter reduction ( P = .25). Mean (standard deviation) of log 10 CFUs per milliliter collected during ultrasonic scaling in the control and test groups were 3.61 (0.95) and 3.30 (0.88), respectively. All samples contained α-hemolytic streptococci, and many samples contained strictly oral anaerobes. Conclusions A significant amount of contamination occurred during ultrasonic scaling in both groups, as indicated by high numbers of CFUs and the identification of strictly oral anaerobes in all plates. Practical Implications Neither device reduced aerosols and spatter effectively, and there was no significant difference in reduction between the 2 devices. Additional measures should be taken with these devices to reduce the likelihood of disease transmission.

Quantity & quality analysis and associated management practices of solid waste generated in the general dentistry offices in the city of Arak, 2015
Arak Medical University Journal, 2016Co-Authors: Ali Koolivand, Mohammad Javad Ghanadzadeh, Mohammad Sadegh Rajaee, Masoumeh, Rahim MousaviAbstract:Background & objectives: As dental solid waste are among the most important environmental pollutants due to its high contents of toxic and hazardous agents, suitable treatment and management of it are of great importance. The objective of this study was to quantity & quality analyses of dental solid waste and associated management practices in the general dentistry offices in the city of Arak. Materials & Methods: 15 samples of solid waste were taken from the 5 selected general dentistry offices, classified into 66 components and 4 fractions, and then the quantity & quality characteristics were evaluated. Management practices of the solid waste were also investigated by using a questionnaire. Results: According to the results, per capita and the average generation rate of each dentistry office were 66.71 g/day-patient and 1340.45 g/day, respectively. Potential infectious, domestic-type, chemical & pharmaceutical, and toxic wastes consisted of 54.25%, 35.14%, 8.19%, and 2.14% of the waste generated, respectively. 10 components including latex gloves, nylon & plastic, Saliva & blood-contaminated kleenex, paper & cardboard, used ampoules, Saliva Ejector tubes, gypsum, food waste, Saliva & blood-contaminated dental rolls, and nylon gloves were responsible for more than 80% of the total waste generated, respectively. Conclusions: Each fraction of dental solid waste (toxic, chemical & pharmaceutical, potential infectious and domestic-type wastes) should be separately collected and disposed of according to the related criteria.

Investigation on the characteristics and management of dental waste in Urmia, Iran
Journal of Material Cycles and Waste Management, 2015Co-Authors: Ali Koolivand, Fathollah Gholami-borujeni, Heshmatollah NourmoradiAbstract:The objective of this study was to identify the components, composition, generation rate and management of dental waste in Urmia, Iran. Fifteen dental centers including eight general dental offices, five specialist dental offices and two dental clinics were selected and two samples were taken from each office. Then, the wastes were manually separated in 31 components and weighted. The results showed that total dental waste generation in all general dental offices, specialist dental offices and dental clinics were 58.94, 17.92 and 10.22 kg/day, respectively. Domestic, potentially infectious, toxic and chemical and pharmaceutical waste also constituted 35.46, 34.24, 11.83 and 5.56 % of total waste, respectively. Only 11 components including blood-contaminated paper towel, Saliva-contaminated paper towel, Saliva-contaminated cotton, extracted teeth, blood-contaminated gauze, inseparable components, nylon glove, tongue blade, latex glove, Saliva Ejector and blood-contaminated cotton constituted more than 80 % of total infectious waste generation. There was no management program (waste minimization, separation, reuse and recycling) in the dental offices. Source reduction, separation, reuse and recycling activities should be conducted to decrease the hazards of dental wastes. It is also suggested that each fraction of dental waste should be separately collected and disposed in the accordance with its related criteria.
