Rajeevan Mahendran, Addison Dental Practice, United Kingdom

I feel that I am an important health professional.

Why you might ask? As a dental surgeon, I promote oral health and prevention of dental disease and am privileged to work closely with patients.

Wide appreciation of general medicine

Although my primary concern is with oral health, there is a wide appreciation of general medicine. There is a general application of applied oral science which involves the investigation of the causes and prevention of tooth erosion and wear. The application of molecular oral science focuses on fundamental issues in cell biology and microbiology as related to health and disease, integrating basic science research with clinical priorities and outcomes.

A dental surgeon has undergone an aggressive course of study involving anatomy, physiology, pathology and microbiology of the human body and other sciences such as biochemistry, pharmacology and oral medicine/oral surgery. These have direct impact on the way treatment is carried out. For example, pathology and microbiology involve inflammation, immunology, control of infectious disease, infectious diseases of body systems, molecular and cellular basis of cancer. Paediatric dentistry involve dental care of children, prevention, restoration and casualty care for healthy children with straight forward dental needs.

“The treatments for the patients on this day…”

I work at The Addison Dental Practice, which covers about 20,000 or so patients of all ages for various problems. There are four dentists in this practice and each have their own lists. On the 12th April, my list consisted of 18 patients out of which two were new.

The treatments for the patients listed on this day were categorized as fillings, extraction, cleaning, root canals, cosmetic dentistry, orthodontics, treatment of gum disease, and dental implants. Tooth decay is a common problem caused by bacteria and improper dental care which leads to cavities. In extreme cases teeth are extracted. Investigation is carried out with the aid of x-rays. Other dental treatments are root canals (endodontics), treatment of gum disease (periodontics), crowns and bridges (prosthodontics).

Orthodontics is a branch of dentistry concerned with straightening of the teeth. Its aim is to produce a healthy functional site, creating greater resistance to disease and improving personal appearance. Dental implants are small titanium cylinders that are surgically inserted into the bone of the jaw. A restoration or denture is then anchored to the implants.

Teeth whitening is part of cosmetic dentistry. Here, a high concentration whitening gel is carefully applied and activated with a high density light. Hydrogen peroxide in the gel penetrates the enamel and removes underlying stains and discolouration. All the treatments that were carried out during the day were according to proven scientific procedures that have been established in this profession.

Professional responsibility


Like any other health professional, I am ultimately responsible for leading my own team of staff. I am able to develop a high standard of professional responsibility by working closely with my patients. I feel that this is an intellectually stimulating career, largely based on scientific principles, but which can encompass artistic flair. A continuing commitment to education is needed due to the constant presence of new challenges with the introduction of new techniques and use of new materials.
