This item was used during my student days, but it's in good condition for a used item. It contains descriptions of systemic diseases, infectious diseases, mental illnesses, and pregnant women. I think it's content that's beneficial to know not only for dental hygienists but also as general knowledge. Medical books are expensive and difficult to buy individually, so I would be happy to sell it at a low price to those who want to study(*´`) Feel free to negotiate the price.
