Quick tips to get to the root of periodontal disease

If pets in your veterinary clinic are plagued by plaque, take a moment to review Dr. Barden Greenfield’s advice on pockets, probing and why you should always keep a backup scaler tip.

And this huge number may be on the rise thanks to an increase in the popularity of smaller dogs, which typically experience periodontal disease at a younger age.

CVC educator Barden Greenfield, DVM, DAVDC, explains that at the root of periodontal disease is plaque (which contains 100 trillion bacterial cells in every gram) under the gum line. It causes “pockets” to form around teeth as bone and gum tissue, which normally fit tightly around each tooth, are destroyed.

The goal of periodontal therapy is to prevent bone loss, because bone loss is a big deal. In humans, alveolar bone loss increases risk of death more than smoking.

To determine the amount of bone loss, Dr. Greenfield says you’ll need to use a probe to measure periodontal pocket depths. Radiographs can’t detect cortical bone loss until it reaches 40%. Thus, it’s important to trust your probes because it’s possible to have significant bone loss before it shows up on a radiograph. Dr. Greenfield specifically recommends Williams probes.

Gram-positive bacteria in the mouth aren’t a source of worry, Dr. Greenfield says. It’s when they convert to the gram-negative anaerobes that they wreak havoc. Plaque bacteria are 100 times more resistant to antiseptics, and antibiotics won’t resolve the problem either. But mechanical removal will.

When removing the plaque under the gums, don’t forget to also remove the subgingival epithelium. And remember to change your scaler tips every month or so too. Doing so will save you time in the long run. Dr. Greenfield advises to always keep a backup scaler tip. (I learned the importance of this the hard way when the scaler tip broke halfway through a dental. The client never came back to finish.)
