Gingivitis versus periodontitis: Dental assisting

Gingivitis and periodontitis are types of periodontal disease caused by bacterial plaque, also known as dental biofilm, which is a sticky, colorless coating that adheres to the teeth and oral mucosa. Periodontal disease is a communicable inflammatory process that affects the periodontium — the structures that surround, support, and attach to the teeth. If left unchecked, periodontal disease can trigger a cascade of inflammation resulting in a wide range of effects throughout the body. As a dental assistant, recognizing gingivitis and periodontitis is essential, and your role in spotting it early is key.

Alright, first let’s break down the difference between gingivitis and periodontitis. The term gingivitis comes from gingiva, meaning gums, and -itis, which means inflammation, so it literally means inflammation of the gums. Gingivitis is the earliest stage of periodontal disease; but here’s the good news: it’s reversible. With proper oral hygiene and care, the tissue can return to health.

Periodontitis, on the other hand, is a more serious condition. The word periodontitis comes from peri- meaning around, odont meaning tooth, and -itis for inflammation. It happens when the inflammation gets worse, and spreads to the soft tissue and bone surrounding the teeth, called the periodontium that support the teeth and hold them in place. As inflammation progresses, the periodontium breaks down, leading to destruction of the bone and loss of attachment. Once this damage occurs, it’s irreversible. As a dental assistant, knowing the difference helps you remind your patients about the importance of good oral hygiene.

So, just how does periodontal disease develop? The first step involves the formation of dental plaque that accumulates if it isn’t regularly removed by thorough toothbrushing and flossing. The bacteria in the plaque cause inflammation and produce enzymes and toxins that damage the periodontal tissues. Over time, the plaque can transform into a hard, stone-like deposit called a calculus, commonly known as tartar, that can only be removed by a dentist or dental hygienist using scaling instruments. Unfortunately, the rough surface of the calculus provides an ideal surface for additional growth of plaque, which leads to persistent inflammation.

Periodontitis develops as inflammation progresses and extends deeper, damaging the tissues that anchor the teeth, including the connective tissue and the alveolar bone which is the part of the jawbone that holds the teeth in place. The gums start to separate and form periodontal pockets between the teeth and gums, allowing bacteria to thrive and further destroy tissue.

Okay, now let’s talk about what signs and symptoms you’ll actually see. In gingivitis, the earliest sign is bleeding, especially during brushing or flossing. The gingiva may appear red, swollen, and shiny, but there is typically no pain. Importantly, there is no attachment loss and no bone loss at this stage, which is why gingivitis is reversible.
