幾個牙醫的聯合的診所

In my area, I have one "幾個牙醫的聯合的診所". But it seems those kinds of dental offices all have very poor dental equipments. The one I have visited before uses old x-rays machine, not digital one. Old x-ray has much high radiation compared to the digital one.

Don't know where I can find 牙科學院的臨床牙科.
