NCRP 145 gives effective doses for intraoral full mouth series and 5-10 mrem per series with film is a good ballpark.  With digital receptors you can cut that by up to half.  Technique, cone length and cone shape all make a difference here too.

Panoramic is somewhere circa 1-2 millirem per scan (values vary again with technique, unit, etc...).

Dental CBCT has effective doses from about 6 to 26+ per scan depending on unit, scan area and technique factors.
