Breaking the chain of infection

27 December 2023

Julia Svec details the essential steps to take to reduce transmission.

‘Prevention’ is an important topic across many areas of dentistry, including when reducing the spread of infection. To protect patients and staff, dental practices must have strict protocols in place, which are continually evaluated to ensure optimal measures are being implemented. Pathogens spread easily in environments like a dental practice, so the team must be vigilant against all the possible avenues of infection.

Don’t weaken your defences

If the past few years have taught us anything, it is that infection spreads incredibly quickly, and everybody plays a vital part in its prevention. Within the practice, there are several modes of infection transmission: direct contact with bodily fluids; indirect contact with contaminated instruments, surfaces or equipment; infected droplets entering the airway from coughing, sneezing or talking; and airborne transmission due to microorganisms remaining suspended in the airflow for extended periods of time. All practices must follow strict regulations, in addition to continually assessing whether any areas of their infection control need improving. This way, you can rest assured that you are disrupting the chain of infection and that your practice is safe and clean.

It is necessary to review all areas of your decontamination and disinfection processes to ensure there are no weaknesses in your preventative workflow.

Hand hygiene

Addressing the range of threats that present themselves in the practice and ascertaining where improvements can be made requires a team effort. Oftentimes, education and reiteration of the basics can be imperative, as they are usually the measures that ensure the greatest protection. For example, hand hygiene is considered the gold standard in preventing the spread of infection. According to the World Health Organization (WHO), thorough hand hygiene measures prevent up to 50 per cent of avoidable infections acquired during health care delivery, and that includes those which can impact the staff. This simple yet vital step is the first line of defence against infection. Ensuring that both staff and patients are practising better hand hygiene habits should be a top priority. The utilisation of posters and signage can help to prompt both patients and staff to keep their hands clean: providing high-quality soap and hand sanitiser, especially in the bathrooms and waiting rooms, are likewise handy reminders.

Surface disinfection

Surfaces are another area where contamination can easily occur and be transmitted to other objects and personnel. Even with meticulous hand hygiene, a contaminated surface can re-contaminate the skin and, therefore, renew the threat of infection. Research postulates that many species of bacteria can survive for extended periods of time on a range of surfaces. For example, Mycobacterium tuberculosis and C. difficile can survive for months, viruses like astrovirus and hepatitis A for around two months, and herpes between two hours and eight weeks. Survival periods are dependent on the environment and surface; regardless, all surfaces (especially those frequently touched) must be decontaminated regularly.

Of course, in addition to decontaminating surfaces in the ‘dirty zone’, such as the dental chair, equipment and cabinetry, surfaces in the waiting/reception area should not escape scrutiny. This is especially true of touchpoints like door handles, chairs, computer keyboards and other surfaces that are routinely in contact with different people. The literature supports the notion that education, training and targeted microbiological control play a key role in improving cleaning performance and infection prevention.

The right products for the job

Together, stringent hand hygiene and surface decontamination are effective at protecting patients and staff from the spread of infection. Alongside continual compliance, you need to use the right products for the job. This should be a carefully considered decision as solutions must be compatible with the variety of surfaces in the practice. Nowadays, there is a heightened focus on products that utilise more natural ingredients, with no compromise in protection. Many cleaning products contain chemicals and agents that, while traditionally effective against pathogens, can be potentially harmful to health.

The Citrox Protect range of solutions, distributed by Oraldent, features a non-toxic, non-allergenic, non-corrosive and non-carcinogenic formula based on organic acids and containing Citrox complex. Independently proven effective against a variety of pathogens, you can rest assured that Citrox Protect products provide peace of mind. The portfolio includes surface disinfectants, hand sanitisers and textile sealing products: a comprehensive range to suit the complex needs of dental practices.

Getting the basics right

Infection control must always be stringent in the dental practice. However, the risk of transmission is always omnipresent so avoiding weak areas in your infection control protocols is essential. With continuous assessment, team training, education and the right products, you can ensure that the transmission of infection is kept to as much a minimum as possible, making your dental practice a consistently safe and clean environment.
