  This short article is the abstract of the part of the " Crown and Bridge 3-day practical course " for ADC practical examination A variety of factors have to be considered for the construction of a bridge. Span of the edentulous area Type of the teeth being replaced Quality of supporting teeth Conditions of the teeth in the opposing arch Age of the patient Patients’ ability to bear the treatment cost Span of the edentulous area  means how many teeth have to be replaced by bridge. The greater number of teeth to be replaced, the longer will be the bridge; that in turn, will cause more stress in the bridge itself as well as onto the supporting teeth known as abutments. More stressed bridge will get more fractured ceramic from the metal part. Type of the teeth  decides as to how much masticatory load will have to be borne by the abutments. In case of the lateral incisor pontic, supported by one central incision and one canine, the masticatory load over abutments will be mini...

A dentist who has got a bachelor's degree from a non-Australian institution needs to pass the skill assessment examination conducted by the Australian Dental Council (ADC) and then needs to register oneself in Dental Board of Australia to practise as a general dentist in Australia or to get a job in public or private sector.   The ADC examination is a screening examination to establish that dentists trained in dental schools which is not formally reviewed and accredited by the ADC, have the necessary competence to practise dentistry in Australia.   Following are the steps, an overseas dentist needs to go through to qualify the ADC examination:  

Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus (HBV). It can cause chronic infection and puts people at high risk of death from cirrhosis and liver cancer. In the first part of the article, you have read the epidemiology, mode of transmission of Hepatitis B virus, its sign and symptoms, groups at risk, the relationship of HBV and HIV infection, and how the diagnosis is confirmed. In this part of the article, we shall discuss about its treatment and prevention. You can also take a free mock test on Hepatitis B.

Overview   Hepatitis is an inflammation of the liver that's caused by a variety of contagious viruses and non-infectious  agents leading to a range of health problems, some of which can be fatal. There are five main strains of the hepatitis virus, known as types A, B, C, D and E. While their infection results in liver disease, they differ in important ways including modes of transmission, severity of the illness, geographical distribution and prevention methods.   Particularly types B and C lead to chronic disease in hundreds of millions of people and together are the most common cause of liver cirrhosis, liver cancer and viral hepatitis related deaths.   An estimated 354 million people worldwide having no access to testing and treatment live with hepatitis B or C.   Some types of hepatitis are preventable through vaccination. A WHO study found that an estimated 4.5 million premature deaths could be averted in low-and middle- income countries by 2030 through vac...

The 'custom trays' also known as 'special trays' are fabricated so that the final impression of the patient’s edentulous mouth can be made accurately using selective pressure technique with proper border extensions. The selective pressure technique helps in making the impression in such a way that when the newly fabricated dentures are in function in the mouth of the patient, they exert pressure only on those areas of the mouth that can withstand the masticatory load. The selective pressure technique of impression making spares the non-pressure bearing areas of the edentulous jaw and thus eliminates the possibility of trauma resulting in ulceration and pain in the oral mucosa.   The special tray is made on the primary cast that has been prepared of plaster of Paris by pouring the primary impression made in alginate or impression compound. The impression taken in impression compound records the mucosa in a compressed state whereas the impression taken with alginate rec...

Traumatic ulcers in healing stage caused by sharp teeth An ulcer is a tissue defect which has penetrated the epithelial-connective tissue border, with its base at a deep level in the submucosa, or even within muscle or periosteum. An ulcer is a deeper breach of the epithelium than an erosion or an excoriation, and involves damage to both epithelium and lamina propria.

Schematic diagram showing implant components and how a crown is placed on implant which in turn placed in a bony socket in the jaw bone People often ask me; can I get a fixed artificial teeth? While most of the time, they can get it, but in few unfortunate one, it remained impossible to provide a fixed partial denture due to their unfavourable oral conditions. In those cases, we suggest them, “you should take an implant supported prosthesis”.

Schematic diagram showing implant components and how a crown is placed on implant which in turn placed in a bony socket in the jaw bone Implant supported prostheses that include over-dentures, crowns and bridges are the treatment of choice in modern dentistry. They are very predictable in nature and have a track record of very successful life span serving their purpose. But, there are certain conditions where the dental implants cannot be provided due to the inherent nature of the disease. The implant supported prostheses are contraindicated in the following conditions: Immune disorders (leukemia) Cancer Disorders of coagulation (anticoagulants, liver cirrhosis, thrombocytopenia, tendency to hemorrhage) Rheumatoid disease (steroid medication) Unstable endocrine disorders Chemotherapy (i.e. bisphosphonates) and radiotherapy within the last 5 years Patients under 16 years old (incomplete development of bones) Psychosis Pregnancy

Therefore, it becomes paramount important for a dentist to know the effects of large doses of ionizing radiation on oral mucosa. In this section, we shall talk about the effects of radiation on oral tissues.
