Lightning Round: The 3 musketeers of dental work

It's that time again! Jim Cramer rang the lightning round bell, which means he gave his take on caller favorite stocks at rapid speed:

Ziopharm Oncology: "I think that they've got good partners, but you have to understand that this is one of those companies that when you have a Celgene, you have a Biogen, when you have an Amgen still well off their highs, you want to go with the higher, bigger guy! That's my suggestion."

ConocoPhillips: "They say the dividend is safe, the problem is that it is often out of control as we learned with Kinder Morgan. I know that the rating agencies want to downgrade these guys repeatedly. I am not a fan of ConocoPhillips."

Box Inc: "I think it's an inexpensive stock. People don't want to own these kinds of stocks right now, and I think you are going to be wrong and there is real value at $13. Maybe $18, no, but $13 yes."

Henry Schein Inc: "Henry Schein, Sirona Dental and Patterson are the three musketeers of dental work! I like them all."
