Doctors are also human being. Doctors attribute to their profession behind closed doors. As patients, we are so overwhelmed with our own problems. We fail to notice that our doctor may be battling her own problems with a complicated system. They are stuck in a systemic mess. Patients bargaining and don’t pay up regularly. Medico Legal threats. Costs are rising in every things day by day but when doctors rise treatment costs, they have to give justification so much. Life-and-death ethical dilemmas. Burnout. Loss of value in society.

A child's age is not always an accurate indicator of dental development This means that some children develop and grow their teeth quickly while others do not. There are a variety of causes for delayed dental development and in most cases they are not given an importance and concern as long as permanent teeth grow eventually. Every child should be seen...
