Infection control in the dental clinic

Blogged under Dental Education by DrJean on Friday 28 December 2007 at 11:35 pm

The mouth carries a large amount of potentially infective microorganisms.Saliva and blood are common vectors of infection.Most people who are carriers of various micoorganisms are totally unaware of it.In other words,you don’t know what kind of bugs your neighbour or your colleague or even your spouse has in his or her system.

Therefore,there must be a consistent infection control protocol that needs to be adopted for all in the dental clinic.

As much as possible,there should be liberal use of disposable equipments.These are single-use items that are used once and discarded.In the dental clinic,examples of disposables would be the patient’s bib,rinsing cup,saliva ejector(the suction thingy that they put in your mouth to get rid of all the water and saliva),local anaesthetic needles and catridges,surgical blades etc.

The other instruments or equipments that have to be reused will have to be properly sterilised.

Decontamination should be primarily done away from the surgery in a designated sterilisation area.This area would have the autoclave,the ultrasonic cleaner and sinks to wash the instruments.


All instruments contaminated with oral fluids should be thoroughly cleaned and sterilised.Cleaning can be done by hand or by using the ultrasonic cleaner before proceeding to sterilise them.

The method of choice for sterilisation is autoclaving.The autoclave has the capacity to sterilise dental instruments  from 134-137 degrees Celcius. This would eliminate practically all microorganisms as well as spores.


For instruments that cannot be placed in such high temperature,they have to be soaked for a designated time frame in a cold sterilisation solution in order for these instruments to be completely free of microorganisms and spores.

Once sterilised,the instruments need to be stored and covered.Sterilisation pouches can be used to store instruments to keep them sterile until the next use.

In the surgery,in between each patient,surface decontamination needs to be carried out.All work surfaces should be thoroughly cleaned  and disinfected with a suitable surface disinfectant.

It is the resposibility of your dentist and the staff of the clinic to ensure that all precautions are taken to prevent any form of cross infection between patients.

We love celebrations!

I love celebrations.I would jump at any opportunity to celebrate.My children will be able to tell that we celebrate quite a bit at home.Not just birthdays ,anniversaries or festivals.We went for MacDonalds(which is a treat to my children) when my daughter got the “Most Helpful Student” award in her 4-year-old kindie class.We went for ice cream when my older son participated in his first Sports Day event.When my husband and I completed our first 10km run,we celebrated,of course.

Naturally,this culture of celebration has rubbed off at work.Apart from the occasional meals we organise,we would steal some time at work to sing birthday songs and blow candles for one another in our little pantry.



Caper Diem! and a very happy New Year to all.

Snapshots from Christmas 2007

Blogged under Personal by DrJean on Thursday 27 December 2007 at 7:15 am

Christmas has come and gone,again….how fast time flies!

It is a time for me to count my blessings and to be thankful yet again for so many things,mainly for my health and my family.And friends.

It is also time for me to share,and sharing food is one thing I can do fairly well 🙂

And here are some pictures to share…


As usual,the iSmile team and their spouses went out to have a nice meal,something we have grown REALLY good at!


Some cakes are just too pretty to eat!



The UM Dental Faculty Students had their annual Christmas party at my home.


And this year,I decided to give the turkey a miss after finding out how exorbitant the price is.Instead, I got my SS2 market chicken seller to source for the biggest chickens she could find.She did well and even delivered the chickens to my house.And they taste just as good,stuffed and roasted.


My children were involved in a Children’s Christmas production in church.
