Secodontosaurus tooth?

Teeth from the Permian are often difficult, nigh impossible to identify with confidence. This tooth is strongly carinated, with the carinae proceeding to the base of the crown. It has no labio-lingual curvature and an irregular enamel texture. My best guess at the moment is a synapsid, something like Secodontosaurus.

After finding the redescription of the cranial material of the type specimen, I believe this tentative ID is still reasonable:

 

"All the preserved maxillary teeth have anterior and posterior cutting edges, but they lack serrations. The anterior cutting edge is present only along the apical half of the tooth and extends from the medial surface basally onto the anterior edge apically. The posterior cutting edge extends vertically almost the entire height of the tooth... The anterior dentary teeth are slender and sharply pointed...All the preserved dentary teeth have cutting edges of similar design to those on the maxillary series and also lack serrations." (Reisz et al. (1991))

 

Unfortunately part of the anterior carina is missing, so not a slam dunk.
