“…Esses aparelhos lan-110 çam, até aproximadamente um metro ao redor da área operatória, aerossol salivar repleto de microrganismos provenientes da cavidade bucal. As mãos contaminadas do profissional em contato com diversas superfícies também contribuem para espalhar microrganismos, proporcionando o aumento do risco no processo de transmissão desses microrganismos entre pacientes e entre os membros da equipe odontológica 3,15,16,24 . Dentre os microrganismos encontrados, observou-se maior prevalência de estreptococos bucais, presentes em todas as superfícies analisadas (Tabela 1), totalizando uma média de 7,8 ufc/placa.…”

RESUMO:Desinfecção de superfície é um procedimento realizado nas áreas externas do equipamento odontológico e demais itens do consultório. O objetivo deste trabalho foi analisar a ação de quatro desinfetantes utilizados em Odontologia: álcool etílico a 77°GL, composto fenólico (Duplofen), iodóforo (PVP-I) e solução de álcool etílico a 77°GL com 5% de clorexidina para desinfecção de superfície. Foram analisados quatro pontos em cada equipamento ("carter", pia de lavagem de mãos, encosto de cabeça da cadeira e superfície frontal externa do refletor), utilizando-se a técnica de "spray-wipe-spray". De cada ponto, foram coletadas amostras utilizando-se placas de superfície contendo ágar Mitis Salivarius bacitracina sacarose, ágar Sabouraud Dextrose com cloranfenicol, ágar MacConkey e ágar-sangue para contagem de estreptococos do grupo mutans, leveduras do gênero Candida, bactérias gram-negativas e contagem total de microrganismos, respectivamente (ufc/placa). Os resultados foram analisados estatisticamente utilizando-se teste t de Student para comparação entre as médias de ufc/placa. O desinfetante que demonstrou ser mais efetivo na redução microbiana foi a solução alcoólica de clorexidina, principalmente para bactérias gram-positivas. O iodo e o composto fenólico mostraram ser bastante eficazes na redução microbiana. O álcool etílico a 77°GL foi o menos eficaz dos quatro desinfetantes analisados, mas apesar de não ser indicado como desinfetante de superfície, mostrou, no presente trabalho, redução microbiana estatisticamente significativa após o processo de desinfecção.

The aim of this study was to analyze the efficacy of 4 surface disinfectants utilized in dentistry: 77°GL alcohol, phenolic compound (Duplofen), iodophor (PVP-I) and 77°GL alcohol with 5% of chlorhexidine. Four surfaces of the equipment were analyzed in the study (the carter, the washbasin for hand-washing, the headrest of the chair and the external surface of the reflector), and the spray-wipe-spray procedure was carried out. From each surface, samples were collected by means of surface plates containing Mitis Salivarius bacitracin sucrose agar, Sabouraud Dextrose agar with chloramphenicol, MacConkey agar and blood agar, for counting mutans streptococci, Candida yeasts, gram-negative bacteria and total microorganisms, respectively (ufc/plate). The results were statistically analyzed by means of the Student's t test in order to compare the mean ufc/plate values. The most effective disinfectant was 77°GL alcohol with 5% of chlorhexidine, mainly against gram-positive bacteria. Iodophor and phenolic compound were also effective in microbial reduction. 77°GL alcohol was the least effective product -however, although it is not considered as a surface disinfectant, it produced, in this study, statistically significant microbial reduction after t...

“…Studies of similar nature have demonstrated that immunization of dental teams toward bacterial and viral infections by diseasespecific or nonspecific (e.g., gamma globulin) vaccines remains important [27]. One research in Melbourne, Australia, showed that just 5 out of 14 dental clinics processed and disposed of their hazardous waste according to the guidelines [28]. A research carried out in New Zealand observed that 24.45% of sharps discarded from dental clinics were discarded as household waste [29].…”

Aims and Objectives. This study aims to assess the knowledge, attitude, and perceptions of dental asepsis and sterilization among dental assistants in Pakistan. Materials and Methods. A cross-sectional study was carried out. A 27-item prepilot tested close-ended questionnaire was designed and administered online to collect data on knowledge of asepsis, sterilization, instrument handling, disinfection, hand-hygiene practices, dental practice, age, education, and experience level from March 2020 to June 2020. Results. Out of 70 dental assistants, the majority were aged between 21 and 29 years (44.30%), more than two-thirds (85.41%) of the dental assistants were working in a hospital, while 14.29% were working in private clinics, only 7.1% had a diploma in the dental assistant program, and 74% had more than 2 years of experience in practice. Dental assistants working in private practice (76.30) had a higher mean knowledge scores compared to those working in hospital (74.25), while those with less than 2 years of experience (75.61) had a higher scores compared to those with 2–5 years of experience (73.96). Conclusion. Better compliance with recommended infection control and waste management practices is needed for all dental assistants. Continuing education programs targeting such awareness are vital to improve the management of hazardous waste practices among dental assistants.

“…Based on the results of a study conducted in Sydney, all 14 dental offices in the city used autoclaves for sterilizing equipment; 12 had chemical disinfectants for disinfection of surfaces. 27 Ensuring the proper function of these devices for sterilization can be an effective step to control infections transmitted through dental instruments and equipment.…”
