cal

Clinical Attachment Level.

fgm

Free Gingival Margin.

filled

Number of filled surfaces.

decay_new

New decayed surfaces.

decay_recur

Recurrent decayed surfaces.

crown

Crown indicator; 1 = tooth has a crown, 0 = no crown.

endo

Endodontic therapy indicator; 1 = endo therapy performed, 0 = no endo therapy.

filled_tooth

Filled tooth indicator; 1 = filled, 0 = not filled.
