“…This represents important protection for the dentist and dental hygienists, who are the main targets of the microorganisms generated during oral procedures. 6 It is important to emphasize that the dental/surface barriers, the methods most commonly used to minimize cross-infection in the dental office, do not reduce the levels of microorganisms in the environment. Pre-procedural rinsing provides a viable CPC: cetylpyridinium chloride; Zn: zinc lactate; F: sodium fluoride; CHX: chlorhexidine digluconate; %: percentage.…”

The aim of this randomized, single blinded clinical trial was to evaluate the effect of a pre-procedural mouthwash containing cetylpyridinium chloride (CPC), zinc lactate (Zn) and sodium fluoride (F) in the reduction of viable bacteria in oral aerosol after a dental prophylaxis with ultrasonic scaler. Sixty systemically healthy volunteers receiving dental prophylaxis were randomly assigned to one of the following experimental groups (15 per group): (i) rinsing with 0.075% CPC, 0.28% Zn and 0.05% F (CPC+Zn+F), (ii) water or (iii) 0.12% chlorhexidine digluconate (CHX), and (iv) no rinsing. Viable bacteria were collected from different locations in the dental office on enriched TSA plates and anaerobically incubated for 72 hours. The colonies were counted and species were then identified by Checkerboard DNA-DNA Hybridization. The total number of colony-forming units (CFUs) detected in the aerosols from volunteers who rinsed with CPC+Zn+F or CHX was statistically significantly (p<0.05) lower than of those subjects who did not rinse or who rinsed with water. When all locations were considered together, the aerosols from the CPC+Zn+F and CHX groups showed, respectively, 70% and 77% fewer CFUs than those from the No Rinsing group and 61% and 70% than those from the Water group. The mean proportions of bacterial species from the orange complex were statistically significantly (p<0.05) lower in aerosols from the CPC+Zn+F and CHX groups compared with the others two groups. In conclusion, the mouthwash containing CPC+Zn+F, is effective in reducing viable bacteria in oral aerosol after a dental prophylaxis with ultrasonic scaler.

“…The use of certain equipment such as ultrasonic devices, 1,2,3,4,5 highspeed dental handpieces 6,7 or three-way syringes 8 may spread aerosols and splatters containing microorganisms in the environment. These microorganisms may cause cross-infections in the dental office, jeopardizing the health of patients and dental professionals.…”

Four standardized locations of the operatory were chosen to be evaluated for each patient using blood agar plates placed at -operator's chest area, patient's chest area and at a distance of 12 and 24 inches from the operating area attached with the help of a headrest extension device 6 on a standardized chair with controlled frequency and water pressure during treatment procedures. the average distance between patient's mouth and his own chest was 12 inches and to dentist's chest was 10 -12 inches.…”

Aerosol and splatter are a concern in dentistry because of possible transmission of infectious agents and their potential effects on the health of patients and dental personnel. the aim of this study was to assess and compare amount of aerosol contamination produced by ultrasonic scaler and high speed air turbine hand piece in immediate vicinity of patient's mouth during dental procedures and to determine level and type of microbial contamination present on white coats of dental personnel in a rural dental setting. the study was conducted in two parts, with assessment and comparison of amount of aerosol contamination produced by ultrasonic scaler and high speed air turbine hand piece in first part and examination of fifty one white coat's contamination of dental personnel in second part. Higher colony count was seen during oral prophylaxis which was significantly than during cavity preparation; and the count was highest from patient's chest area. Dental procedures like scaling and cavity preparation cause considerable aerosol contamination in the immediate vicinity of the patient's mouth and of dentists' barrier clothing.

O objetivo do estudo foi avaliar a deposição de óxido de alumínio no campo operatório do cirurgião-dentista durante a utilização do sistema de abrasão a ar em consultório odontológico, bem como a efetividade da sucção de alta potência na captação desse pó. Por meio de um dispositivo para a coleta das partículas nos locais correspondentes às posições e distâncias de trabalho do profissional, dentes artificiais foram abrasionados. O sistema de sucção empregado para aspiração das partículas foi o de alta potência com sugador de saliva convencional e sugador com abertura ampliada por funil. A mensuração das partículas foi determinada pela quantidade em massa de óxido de alumínio depositada em placas de Petri. Os resultados obtidos por meio de estatística descritiva gráfica revelaram que a maior quantidade de pó se encontrava a 20 cm do operador e na posição de trabalho 9h, quando foi utilizado o sugador de saliva convencional. Uma vez comprovado que a sucção não é totalmente eficiente na aspiração do pó de óxido de alumínio, reforça-se a importância da proteção individual apropriada para o emprego seguro do sistema de abrasão a ar para pacientes e, principalmente, para os profissionais que trabalham com este tipo de tecnologia.
