Physical agent detection ability of occupational health technical service institutions in Guangdong Province / 中国职业医学

@#Objective To analyze the physical agent detection ability of occupational health technical service institutions in Methods Guangdong Province. A total of 92 institutions in Guangdong Province that participated in the inter laboratory comparison of physical agents organized in 2020 were taken as the research subjects using purposive sampling method. The ， Results certified physical factor items number of measuring instruments and measurement standards were investigated. The ， ， certification and accreditation project on physical agents in 92 institutions with certification and accreditation rate >80.0% ， ， ， - were noise high temperature ultraviolet radiation hand transmitted vibration and illumination. The certification approval rates ， ， ， ， of power frequency magnetic field 1 Hz to 100 kHz electric field 1 Hz to 100 kHz magnetic field laser radiation physical ， - < （ ） labor intensity and whole body vibration were 60.0%. The certification and accreditation rate of noise 98.9% was the ， （ ） （P< ） ， highest and that of the physical labor intensity 3.3% was the lowest 0.01 . As for the number of measuring instruments （ ） the number of noise measuring instruments accounted for the highest proportion 52.6% in 92 institutions. The number of ， （P< ） measuring instruments from the most to the least was grade A grade B and unqualified institutions 0.01 . The number of - （P< ） measuring instruments in private institutions was greater than that in non private institutions 0.01 . In the measurement ， ， standards some institutions that have certified power frequency electric field power frequency magnetic field and microclimate ， - projects still used the abandoned standard. Some institutions that have certified microclimate illuminance and whole body Conclusion ， vibration used the wrong measurement standards. Among the physical agents the certification and accreditation ， rate of noise is the highest and the number of noise related measuring instruments is the largest. The qualified institutions and private institutions have greater number of certification and accreditation projects on physical agents and measuring instruments.

El ruido en el ambiente laboral estomatológico / Noise in the stomatological working environment

Se realizó un estudio observacional, descriptivo y transversal de 59 trabajadores que se encontraban laborando físicamente en el Servicio de Estomatología del Policlínico Docente Julián Grimau García de Santiago de Cuba, desde julio de 2015 hasta igual mes de 2016, con el objetivo de identificar los niveles de ruido existentes en el ambiente laboral de dicho Servicio. En la serie se obtuvo que los departamentos de mayor nivel de ruido resultaron ser: Prótesis (73,2 dB), Ortodoncia y Periodoncia (72,7 dB) y Conservadora (71,2 dB), en ese orden; asimismo, en cuanto al ruido de fondo, las mayores mediciones se registraron en los departamentos de Conservadora y de Prótesis (68,6 y 68,1 dB, respectivamente). Por otra parte, 62,7 por ciento del total de trabajadores presentaron problemas de hipoacusia por estar expuestos permanentemente a este agente físico negativo

An observational, descriptive and cross-sectional study of 59 workers that were physically working in the Stomatology Service of Julián Grimau Teaching Polyclinic in Santiago de Cuba was carried out from July, 2015 to the same month in 2016, aimed at identifying the noise level existing in the working environment of this Service. The departments with higher noise level according to the series were: Prosthesis department (73.2 dB), Orthodontics and Periodontics departments (72.7 dB) and Conservative department (71.2 dB), in that order; as for the back noise, the higher measurements were recorded in the Conservative and Prosthesis departments (68.6 and 68.1 dB, respectively. On the other hand, 62.7 percent of all the workers presented hearing deficit for being permanently exposed to this negative physical agent

La iluminación como agente físico negativo en un servicio estomatológico / Illumination as negative physical agent in a stomatological service

Se realizó un estudio observacional, descriptivo y transversal de 59 trabajadores que se encontraban laborando físicamente en el Servicio de Estomatología del Policlínico Docente Julián Grimau de Santiago de Cuba, desde julio de 2015 hasta igual mes de 2016, con el fin de identificar la iluminación como agente físico negativo en el ambiente laboral. En la serie predominaron el sexo femenino (93,2 por ciento), el grupo etario de 50-54 años (23,7 por ciento), los estomatólogos generales integrales (44,0 por ciento), así como el departamento de Ortodoncia y Periodoncia como el de menor iluminación. Por otra parte, 81,4 por ciento de los trabajadores estaban expuestos a esta problemática y 93,8 por ciento presentaban afecciones oculares. Se evidenció que la iluminación deficiente encontrada en todos los departamentos del mencionado centro resulta perjudicial para la salud de los profesionales de la estomatología

An observational, descriptive and cross-sectional study of 59 workers that were physically working in the Stomatological Service of Julián Grimau Teaching Polyclinic in Santiago de Cuba, was carried out from July, 2015 to the same month in 2016, with the purpose of identifying the illumination as negative physical agent in the working environment. In the series there was a prevalence of the female sex (93.2 percent), the 50-54 years age group (23.7 percent), the comprehensive general dentists (44.0 percent), as well as the Orthodontics and Periodontics department as that of less illumination. On the other hand, 81.4 percent of the workers were exposed to this problem and 93.8 percent presented ocular disorders. It was evidenced that poor illumination found in all the departments of the mentioned center is harmful for the stomatology professionals health
