Coronavirus disease (COVID-19)  is a new strain that was discovered in 2019 and has not been previously identified in humans. The new virus is dangerous - so far, around 20 per cent of confirmed cases have been classed as severe or critical. So far, around 15 to 20 per cent of hospital cases have been classed as "severe" and the current death rate varies between 0.7 per cent and 3.4 per cent depending on the location and, crucially, access to good hospital care. This is much lower than fatality rates for Mers (30 per cent) and Sars (10 per cent), but still a significant threat. HOW DOES IT SPREAD? Like cold and flu bugs, the virus is spread via droplets when a person coughs or sneezes. The droplets land on s...

WHAT IS PULPECTOMY?? Every human tooth has three parts in the crown (part visible in the oral cavity)- hard tissue structures called the enamel and dentin and a soft tissue pulp on the inside. Correspondingly, the root of the tooth has two hard tissues known as the cementum and dentin and a soft tissue structure pulp on the inside. While the enamel , cementum and dentin on the outer layers of the teeth are tough and lifeless, the pulp inside is soft, living, highly sensitive and consists of nerves and blood vessles which provide nutrition and vitality to the tooth. When the outer layers of the tooth are damaged, it is possible for the pulp inside to become infected. In some cases to save the tooth, it may be required that the pulp be removed. This procedure of removal of infected pulp, cleaning of the pulp canals and then filling it with a suitable resorbing material in a milk tooth is known as pulpectomy. WHAT HAPPENS DURING TREATMENT? A pulpectomy is similar to a ...
