Ludwig's angina is the bilateral involvement of infections in the submandibular, submental and sublingual spaces.
As far as cavernous sinus thrombosis goes, realistically, most all spaces can contribute to it. Since there is not counter current system in place, most of the veins in the head have a route where blood can make it to the cavernous sinus. Therefore, if an infection in pretty much any space occurs and it makes it into the blood stream, then it can make it into the cavernous sinus. One space where these are uncommon, but do occur is the infratemporal space where dental infections in the maxillary 3rds.

Bad dental infections in the maxilla => Cavernous sinus
Bad dental infections in the mandible => Ludiwig's
Hope the pictures help related the tissue spaces, the venous drainage and the spread of the bacteria causing the problems. With cst, you have to remember they spread through the venous drainage system anastomoses from the face and orbit to the cavernous sinus and ludwigs spreads through the facial spaces.
