Apache doesn't recognize "-" in my .htaccess

[palomino5]

I'm having a problem with my .htaccess

I don't know exactly what it's happenning but my apache is not recognizing "-" in my .htaccess.

For example, this rule is not being recognized:

RewriteRule ^p-dentista/(.*) /p-dentista.php?pa g=$1

If I use pdentista instead of p-dentista, it works.

Do you know what's happenning??

Thank yoU!!

This happens probably because the docs say:
- (dash)A dash indicates that no substitution should be performed (the existing path is passed through untouched). This is used when a flag (see below) needs to be applied without changing the path.

I think that it should be some apache configuration, because my htaccess was working well in my last server, but the problemas has begun when i moved the web to a new server.
