“…All the dental procedures were analysed as an uniform group, which might be a reason for the result discussed in their study 3 . In the research conducted by Abdelkarim et al, the contaminated surface area using a high-speed air turbine reached 77.3%, but use of dental lasers caused only 3.8% to 7.3% of surfaces to be contaminated 13 . The proportion of surfaces contaminated is shown to be strictly related to the dental technique used, and for this reason, in periodontology manual scaling and polishing was recommended instead of ultrasonic techniques 24 , but some of the contamination might have been caused even from the removal of impacted third molars or routine extractions 11 .…”

“…Special precautions in dental studies during the pandemic period were based on the risk of operating in the open oral cavity with the use of aerosol-generating procedures (AGPs) 1 , 9 , 10 , 11 . Common AGPs in the dental office involve the use of such equipment as high-speed air turbines 12 , 13 . To avoid the potential spread of SARS-CoV-2 during dental AGPs, a high level of personal protective equipment (PPE) is required 3 .…”

Objectives Since the SARS-CoV-2 outbreak in 2019, special safety protocols were introduced in dentistry. Dental professions were established mostly at risk of gaining the virus because of aerosol generating procedures used. This preliminary study, starts the cycle of the laboratory protocols describing the quality and efficacy of laboratory tests in the SARS-CoV-2 IgG detection in the serum of asymptomatic dental personnel during the last quarter of 2020. Methods IgG levels were measured with the use of semi-quantitative enzyme-linked immunosorbent assay (ELISA) in vitro diagnostic (IVD) kit in the serum of study group that consisted of 127 employees of the dental clinic, divided into three subgroups: SUB1: dentists (n=67), SUB2: dental assistants, dental hygienists, nurses, laboratory workers (n=40), SUB3: administrative workers (n=20). Pearson analysis of results from the questionnaires attached to the study protocol were provided, to assure the results compare to the subjects impressions about their general health. Results Positive ELISA IgG results were received in 6% (4 subjects) of the SUB1 group, 7.50% (3 subjects) from the SUB2 group, and 5% from the SUB3 group. Percentage of subjects without work interruption from the beginning of pandemics involved 54% of dentists and 60% of chairside assistants. Conclusion Serum IgG prevalence with the use of semi-quantitative test was low, and further research on the biobanked samples has to be followed, to conclude the levels of IgG with quantitative methods and/or to evaluate the presence of neutralizing antibodies in dental personnel. Since the low representation of seropositivity studies in this group, it will be crucial to confirm the risk of COVID-19 transmission in dental offices.

“…Abdelkarim-Elafifi et al reported that Er,Cr:YSGG reduced the contaminated area by 70% compared to high-speed air turbine. 48 Similarly, aerosol produced by Er:YAG produces less aerosol during orthodontic bracket debonding and root canal irrigation than initial aerosol quantity. 52 However, among dental lasers, high power lasers generate more aerosol or laser plume than low power lasers.…”

Background The advent of dental lasers has overcome the drawbacks of conventional clinical practice. It is considered to be a safer alternative during and post-coronavirus disease 2019 (COVID-19) pandemic in terms of infection control and reduced aerosol production. The study aims to assess the knowledge and practice of dentists toward dental lasers and their use during and post-COVID-19 pandemic scenario. Methodology This is a cross-sectional, analytical study conducted among dental professionals in South India. A total of 444 dental professionals participated in the study. A self-administered questionnaire with 15 closed questions was given to the participants. Chi-square test was used to analyze the obtained data. Results The results indicated that the majority of the dental professionals were aware of the use, the types, watts, wavelength, and types of emission of dental lasers. They had good knowledge about the common uses of lasers in dentistry. Majority of the dental professionals had not used dental lasers anytime in their practice, but are willing to adopt it as a safer alternative option during and post-pandemic scenario. Conclusion Application of knowledge of dental laser into clinical practice is beneficial in improving dental care and to enhance infection control.

Introducción. Históricamente se ha invertido esfuerzo en el diseño de nuevos instrumentos que superen las desventajas del estándar de referencia en cirugía, el bisturí. Como consecuencia de esto, han surgido equipos electrónicos como el electrobisturí y los diferentes dispositivos de tecnología láser. La información disponible sobre estos instrumentos sugiere que la respuesta del tejido intervenido está influenciada por los principios físicos y biológicos de corte del instrumento.Objetivo. Comparar los cambios histológicos en muestras de encía asociados al corte quirúrgico realizado con láser de diodo de 940 nm, láser de erbio, cromo: itrio-escandiogalio-granate (Er,Cr:YSGG) (2780nm) y electrobisturí mediante una presentación de serie de casos.Presentación de los casos. Se presentan tres casos de pacientes sanos sometidos a cirugía estética. El examen clínico reveló la exposición de una banda gingival queratinizada mayor de 4 mm, tejido gingival de color y textura normales, de consistencia firme y sin sangrado al sondaje periodontal. Se indicó gingivectomía con los siguientes protocolos: láser de diodo de 940 nm a 1 W, en modo continuo; láser de Er,Cr:YSGG de 2780 nm a 2,5 W, 75 Hz, modo H, aire 20, agua 40, punta de oro MT4; y bisturí eléctrico en modo de corte, a nivel de potencia cuatro. Se tomaron muestras de tejido gingival y se almacenaron en formaldehído al 10 % para su análisis histológico.Conclusión. Los tres instrumentos de corte generaron cambios histológicos producidos por el efecto térmico; los principales fueron coagulación del colágeno y carbonización.
