While I was working I have pushed my mousewheel while pushing the control key and the whole page began to turn. Is there a button or similiar to reset it?
It's called Canvas Rotation. You can reset via the View menu / Canvas Orientation / Reset Rotation. Or, look at the very bottom right of the screen. You'll see a box labelled 'R' where you enter degrees. Enter zero in the box and hit enter.

You can also right-click on the spinbox for a menu of sensible values, including zero. A lot of Inkscape's spinboxes offer similar menus, which can often be easier to use than typing a value.
If you don't want the possibility of accidentally rotating the canvas with the mousewheel, version 1.0.2 added the ability to turn this off. From the release notes:
Canvas rotation by Ctrl + middle mouse drag / Ctrl + Shift + Scroll can be prevented in two ways:
temporarily for the current document from View → Canvas Orientation → Lock Rotation
for all new Inkscape windows in Edit → Preferences → Interface: Lock canvas rotation by default
Even with it turned off, you can still rotate the canvas using the spinbox, should you wish to.
