2009 FDI World Dental Congress

Blogged under Dental Education by DrJean on Tuesday 8 September 2009 at 9:03 am

I just returned home from Singapore after attending  the FDI Annual World Dental Congress(AWDC) held at the Suntec Convention Centre there from the 2nd to 5th September. The FDI AWDC plays an important role in the advancement of dentistry. This internationally recognised event is held in a different city every year.And it was so good (and definitely so much more economical for me) that this year,it was held relatively close to home because most of the time it is held in the American or European continent.

This event comprises of scientific programmes,exhibitions and meetings by representatives from all over the world to strategize,plan and make policies for the advancement of dentistry in the future.

The scientific programme is an educational event with speakers from around the world presenting on the latest scientific topics affecting the dental profession globally. We had 4 days of lectures to attend,which covered all the various aspects of dentistry.It is quite awesome to be a part of  this huge group of dental practitioners from all over the world,who had gathered together to learn.The speakers were truly chosen from among the best.They go beyond excellence,bringing dentistry to a different level ,in the things they do,whether it be in the area of research or clinical work.

I felt  privileged to be a participant in this event as there is this increasing realisation that dentistry is moving in a direction where changes are occuring so rapidly.We are in the era of practising evidence-based dentistry.We do not just do what the textbooks say and definitely not what we learnt in dental school around 2 decades ago(well at least I am speaking for myself). Things have changed so much that it unnerves me to think that a big chunk of what I learnt in dental school is actually obsolete. Well,it just goes to prove that learning is an ongoing and a life-long process.

The dental exhibition was showcase of state-of-the-art advanced dental technology, equipment and products. Some of the products exhibited were being launched for the first time.

I guess one of the main things that I took home is the assurance that I am doing the right things in my practice and using the right materials for different cases.

Managed to take some pictures with my mobile phone…

It’s the month of Ramadhan again and we took the opportunity to go for “buka puasa”(breaking of fast)dinner together at a hotel in downtown Kuala Lumpur with our team and family members. As usual,we had lots of fun and laughter together…



    and pretty good food too.

Intraoral Xrays

Blogged under Dental Education,Technology by DrJean on Thursday 3 September 2009 at 9:05 am

I take quite a number of intraoral radiographs or Xrays in my daily practice.Most of the time it is the routine few that I need to take in the course of root canal treatment for my patients.I also take them very often to help me diagnose an existing  condition or when I suspect that there is a condition.It is such an essential part of my practice that it is without a doubt that a dentist cannot practice proper dentistry without an Xray facility in his or her office.

Occasionally I get the question of “Is is OK to take so many Xrays?” when I take more than a couple for one patient,which is quite normal in the course of a root canal treatment. I give them the assurance that intraoral Xrays are really extremely low in the radiation it emmits.

An intraoral Xrays emmits an estimated 0.009 mSV. (A millisievert (mSV) is a unit of measure that allows for some comparison between radiation sources that expose the entire body (such as natural background radiation) and those that only expose a portion of the body (such as radiographs). Don’t worry if you do not understand this statement,neither do I!!). Compare that to a chest Xray which emmits approximately 0.080 mSV. This is using conventional Xray films.In the advent of modern technology,we are now moving towards digital Xrays and the radiation used for digital Xrays are reduced by between 70-80%.

Dental radiographs or Xrays are images taken when Xrays pass through your mouth during a dental examination.

How it works is when the Xrays are taken,more rays are absorbed by teeth and bone,which are more dense than the cheeks and gums. The image created is called a radiograph. This can be in the form of a film or an image on the computer screen.

Teeth and bony structures will appear lighter whereas tooth decay, infections and signs of gum disease will, appear darker because of more Xray penetration. Dental fillings  may appear lighter or darker, depending on the type of material used for the particular filling.

Your dentist will be able to observe and  interpretation  these radiographs and can therefore come to a more accurate diagnosis.

Dental  Xrays can provide essential information about the condition of our teeth and our jaw. It is also imperative as a record in the event of identification of a particular individual,for example in forensic cases.

Dental Xrays can show small areas of decay between teeth or under an existing filling,which is usually not detectable by your dentist in the mouth.It can also show bone loss due to tooth infection or gum infection.Some tumours and cysts are also visible from dental XRays,and certain developmental abnormalities can be detected from them. They are also very useful for determining the position of unerupted teeth in the jaw.In cases of trauma,dental XRays play a vital role in observing possible fractures and also the position of the fracture lines.

Hence,we are able to detect and treat many dental conditions in the early stage.

I probably sound redundant,but,dental Xrays are really something we dental practitioners  cannot do without if we want to provide proper dental care to our patients.
