ABSTRACT
OBJECTIVE: This study aims to audit the process of patient management with aerosol-generating procedure (ultrasonic scaling) while adherence to the guidelines for health care workers (HCWs) during the coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: Audits records at the Department of Periodontology at University College of Medicine and Dentistry Hospital, Lahore, Pakistan were collected (prospectively) over the period of October 1 to November 30, 2020 (1st cycle) and December 14, 2020 to February 12, 2021 (2nd cycle). The audit was divided into three components based on the guidelines: (1) physical environment, (2) patients/appointments, and (3) COVID standard operating procedures related to HCWs. RESULTS: The recommended physical layout and procedural factors, as suggested by the guidelines for dental clinics, were observed during the first cycle of audit, and discrepancy of ventilation system was fixed after the first cycle. Audit team reported the observance of fallow time three times daily, which revealed 83.3% observance of fallow time.Later in the second cycle when the extraoral high-volume air evacuator was installed, the fallow time was reduced to 15 minutes and not only five procedural slots per day were created but fallow time was also observed 100% of the time. CONCLUSION: Following the standard guidelines resulted in more efficient working environment and lesser risk for HCWs while performing aerosol-generating procedures.
ABSTRACT
BACKGROUND: Amalgam has been the gold standard for restorations in posterior teeth. Mercury, a major component of dental amalgam, is considered an environmental pollutant. The Minamata Convention on mercury recomends a reduction in the use of mercury-containing products. Since Pakistan is a signatory to the Convention, the same amalgam phase-out limitations are implemented in Pakistan. AIMS: To identify and assess the use of amalgam and its waste management by dentists in Pakistan post-Minamata Convention guidelines. METHODS: A cross-sectional study was conducted in Lahore among 520 general dental practitioners in 2019. RESULTS: The sample size for the study was calculated as 500; the questionnaire was distributed among 550 dentists. Dental amalgam was used by only 41.6% of the dentists in their practice; 55.0% perceived it to be a health risk. Most of the dentists (76.3%) were unaware of the proper disposal protocols for dental amalgam and 76.5% were unaware of any guidelines regarding amalgam use and disposal. CONCLUSION: Although there is a gap in knowledge among the dentists regarding amalgam disposal, dentists in Pakistan are reducing their use of dental amalgam in accordance with the guidelines of the Minamata Convention.
