Infection control in Dental Healthcare

Infection prevention and control is required to prevent the transmission of communicable diseases in all health care settings. Infection prevention and control demands a basic understanding of the spread of diseases; risk factors that increase patient susceptibility to infection; and the practices, procedures and treatments that may result in infections.

How does your dentist protect you?

When you first sit in the dental chair, chances are the first thing you'll see is your dentist washing his or her hands. Hands are washed at the start of the day, before putting on and taking off gloves and after touching any potentially contaminated surface. Your dentist may use a variety of protective items that are used once and then thrown away, including gloves, masks, paper drapes, suction/ water tube tips and needles. Dentists and their assistants can use different kinds of protective gloves. Latex or vinyl gloves are used for patient examinations and procedures and are worn whenever skin could be in contact with body fluids. Between patients, the gloves are thrown away, the hands washed and a new set of gloves used to treat the next patient. For cleaning and sterilizing instruments, heavy rubber utility gloves are used. If you are allergic to rubber or latex, your dentist can wear nitrile gloves, which do not contain any latex rubber proteins etc.

Purpose of infection control in dental healthcare

The purpose of infection control is to reduce the occurrence of infectious diseases. These diseases are usually caused by bacteria or viruses and can be spread by human to human contact, human contact with an infected surface, airborne transmission through tiny droplets of infectious agents suspended in the air, and, finally, by such common vehicles as food or water. In dental healthcare, transmission of infection may occur from the dentist to the patient, from the patient to the dentist or from patient to patient. Patient to patient transmission, although being reported only in medical settings so far, may potentially occur in dental practices.

How dentists prevent transfer of infection

Usually, dental instruments are placed in an ultrasonic bath that contain a detergent/ enzymatic cleaner, which vibrates and removes debris from the instruments. After rinsing, these instruments are placed in an autoclave to sterilize (through intense heat and pressure). Quality control of the autoclave is done weekly with bacterial spore testing. Disposable items and barriers are discarded. Needles and scalpel blades go into a sharps container. Amalgam waste is saved and discarded by a professional service that does annual cleaning of the amalgam separator (the amalgam stuff we drill out doesn't go into regular waste for obvious reasons). Items like handpieces cannot go into an ultrasonic bath (for it can ruin costly equipment), but they do get lubricated and autoclaved. Surfaces (tables, chairs etc.) and others less critical items are wiped with disinfectant (Cavicide) that is bacterialcidal (including TB, HIV, Hep C)

Infection control in Healthcare

Infection control is a series of steps that healthcare facilities and hospitals take to prevent the spread of infectious diseases. It is estimated that approximately 1.7 million preventable illnesses are spread each year. To prevent further spreading of disease, steps that many facilities take include:

  • Ensuring hand hygiene compliance
  • Tracking staff contact with assets and patients
  • Ensuring appropriate environmental conditions for medication, vaccines and biological material

Dr. Harleen helped me with my tooth that was hurting me since 6 months now. I really thank her for the painless and quick treatment. After being treated by Dr. Harleen, I can say that I am no more scared of visiting "Dentists". The staff was very helpful as well and the clinic is very hygienic and well maintained. Thank you Meraki Dental Studio for relieving me of my problem.

Believing in the dictum that no news is good news, I have never ever visited a dentist in my 43 years of existence, till the time I met Dr Harleen - mainly for fear that a dentist might give me some bad news which I didn't want to hear. I think what clinched the deal in her favour - and compelled me to break my informal vow to not see a dentist - was her professional knowledge about her chosen field. It certainly adds to her advantage that she can empathise with a patient's apprehensions regarding a visit to a dentist, which makes her work doubly hard to ensure that each patient, including children, who come to her, have a happy, painless experience. She also makes an effort to keep herself updated about the latest developments & practices in dentistry, which inspires confidence in not just the patient who's visiting, but also to refer her as a dentist of choice to one's friends and family. Add to that her generally sunny disposition & warmth and one can safely say that Dr Harleen is one dentist whom you look forward to visit. One wishes her greater success in her profession.

Who doesn't love painless treatments especially when it comes to visiting a dentist. I am sure everyone has this fear of going to a dentist but not anymore. I am happily satisfied to share my case with Dr. Harleen, a very knowledgeable and warming dentist indeed. She explains and suggest treatments so nicely that the patient would want to trust her blindly. She believes in providing the patient with a complete oral health which not only prevents a person from future oral risks but also providing them with an aesthetically beautiful smile. The assistant and front desk people are also very caring and professional. So if you want to pamper your smile then this is the place. I have found my lifetime dentist for sure and recommend everyone out there to visit Meraki Dental Studio. Kudos to you and your team.

I would like to place on record an appreciation for Dr. Harleen Kalsi of Meraki Dental Studio, South Extension. My twelve-year-old son – Royen – required braces to correct the teeth alignment. He has always been apprehensive about the procedure. On his first visit itself, Dr. Harleen made him completely settled with the procedure and made him willing to take it on. The eventual teeth extractions were painless for him and say that he didn’t even realize when the tooth came off. The following sittings to put the braces and thereafter, were extremely comfortable and relaxing for Royen. He has been well taken care off. The team demonstrated the true spirit of ‘Meraki’ when Royen had visited them alone. They took extra care of him and went out of the way to arrange for his transport back home. They do put in a lot of heart & soul in their noble profession. I am glad that Dr. Harleen Kalsi, of Meraki Dental Studio is there to take care of my family’s oral wellbeing. All the best.

Mr. Rohit Bhatla

Dr. Harleen makes going to a dentist such a happy affair. Her calm demeanor, her professional expertise and her advise take away all the fears one associates with a dentist visit. Thank you Dr. Harleen. May you thrive and cherish, so our smiles, we may cherish.
