ADC Exam Preparation | How to Become Registered Dentist in Australia

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-Part 2: Treatment and Prevention

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.

Hepatitis B: Part 1 - Epidemiology and Clinical Features

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 vaccination, individual tests, drugs and education campaigns. WHO’s global hepatitis strategy, championed by all WHO Member States, aims to reduce new hepatitis infections by 90 and deaths by 65 between 2016 and 2030.

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.

Design of a Custom Tray for Final Impression for Complete Denture

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 records the mucosa in a non-compressed state. From these two opposite states of mucosal records, a dentist proceeds to prepare a special tray that is used to make an impression with pressure on the mucosa in selected areas. We will learn here as to how to make a special tray on a cast that has been made from impression compound.

Oral Ulcers: Clinical features, Causes & Treatment

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.

Five reasons you should take an implant supported prosthesis

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”.

Crown and Bridge: Types and Crown Preparation features

Introduction

A crown is provided to protect the weakened natural tooth, regain its shape, maintain or enhance the esthetics and regain the functional ability of a person. A bridge is a prosthesis that is constructed to replace the one or more missing teeth and is supported by the neighbouring teeth.

They can be constructed in variety of the materials as follows:

Nine reason you should not go for implant supported prosthesis

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:

1. Immune disorders (leukemia)
2. Cancer
3. Disorders of coagulation (anticoagulants, liver cirrhosis, thrombocytopenia, tendency to hemorrhage)
4. Rheumatoid disease (steroid medication)
5. Unstable endocrine disorders
6. Chemotherapy (i.e. bisphosphonates) and radiotherapy within the last 5 years
7. Patients under 16 years old (incomplete development of bones)
8. Psychosis
9. Pregnancy
