INFECTION CONTROL ISSUE | AUGUST 2022
Infection control is a critical element in dentistry. The spread of disease happens swiftly and can result in devastating consequences. At times, the standards and guidelines can seem daunting to maintain and follow; however, with the help of scientific articles and publications guiding our way, we can more easily control and stop the chain of infection.
Remnant oral biofilm and microorganisms after autoclaving sterilization of retrieved healing abutments
J Periodontal Res 2021, Pedro Barreiros et al
Dental implants have gained popularity for many reasons. More clinicians feel comfortable placing them, and they confer a huge benefit to patients who may otherwise struggle with a smile that they feel self-conscious about or even ill-fitting dentures that require more retention. Implants, however, come with a significant price tag not just for patients but for dental offices as well. For this reason, many offices make it common practice to reuse their healing abutments by means of standard cleaning and sterilization procedures. This practice, however, comes with the risk of potentially causing infections due to remnant biofilm that has adhered to the retentive regions of the abutment. The purpose of the following study is to evaluate the effectiveness of sterilizing healing abutments against the biofilms that are adhered to them in order to be safely re-used in patients.
Aerosol-generating dental procedures: a reappraisal of analysis methods and infection control measures.
J Hosp Infect. 2021, K.S Tan et al
Aerosols are a common occurrence in dental offices since the majority of our procedures involve handpieces, ultrasonic scalers, and air/water syringes. Taking into consideration the number of bacteria found in plaque as well as the bacteria that make their way into the oral cavity from our respiratory tract, special care should always be taken when considering the infection control parameters we choose to implement in the office. Such parameters are often decided based on past studies. However, there is a chance that these studies have underestimated the extent of the contamination that is possible following an aerosol-generated procedure (AGP). The following study aims to establish a monitoring protocol that may detect the extent of contamination following an AGP that could then be adopted into future studies to overcome the limitations found in the existing literature.
