Abstract. On the unit ball of an Orlicz function space the (weak star) denting points and (weak star) quasi-denting points coincide. But in Orlicz sequence space the (weak star) quasi-denting points are different from (weak star) denting points. We also show that in Orlitz space the weak star drop property and the Kadec-Klee property are equivalent. Hence the weak drop property and the weak star drop property are independent in Banach spaces.
