Parulis, dog

Parulis, dog

Dog with a draining sinus tract (parulis) associated with an endodontically compromised tooth or root. Note the inflamed granulation tissue opening near the mucogingival junction within the oral cavity. Note also the subtle pink discoloration of the right maxillary canine tooth, an indication that this tooth is nonvital.
