Filter input/htmlentities is necessary when using prepared statements?

When i'm using prepared statements...

1 - Should i use filter inputs? (eg. validade int/sanitize strings) 2 - Should i use htmlentities() when outputing the data from database?

Or filter input still increase the security for the web online application?

Thank you.
