It is a scene common to the dental office.
You come in for your six-month recall appointment. The hygienist cleans your teeth and then has the doctor come in to “check.” This doctor exam is the shortest part of the appointment, but contains vital information. Three areas are assessed: soft tissue health, which includes an oral cancer screening, periodontal health, and tooth health, where the teeth are examined for cavities, fractures and failing restorations.
One area of this exam that I would like to discuss in this week’s blog entry is the periodontal assessment. In assessing periodontal health, I ask the hygienist several questions. The first is how the “pocket depths” were, if there was “any bleeding upon probing or instrumentation” and how you are doing with “home care”.
What am I trying to assess? Pocket depths, or probing depths, measure the depth of the pocket of tissue around the tooth. A normal probing depth is between 1-3 mm. When the hygienist alerts me that there are areas of probing depths greater than 3 mm, I begin to ask more questions, as this may indicate the start of periodontal disease. When I ask if there is bleeding upon probing or instrumentation, I am trying to assess if there is any inflammation in the tissues. This inflammation suggests bacterial infection and is indicative of either gingivitis or, in periodontal patients, the return to a state of infection. Finally, when I ask about homecare, I am asking the hygienist to give an assessment of how you are doing at home with routine oral hygiene. Are you brushing at least twice per day, once in the morning and once before bed? Are you flossing at night before bed? How much plaque and calculus are found on your teeth? Is it a light, moderate or heavy amount?
Based on the answers to the questions, the hygienist and I can give you an accurate status of your periodontal health.
Patients Fall Into One of Three Main Categories
- Healthy Periodontal Patients: Those whose tissues are free from pocketing, inflammation and bleeding
- Patients With Gingivitis: Those who have a reversible inflammation of the gums
- Patients With Periodontal Disease: Those who have either had or currently have active periodontal disease.
The goal in our office is to have people without a history of periodontal disease to remain healthy and disease-free; for those with a history of periodontal disease to remain stable and not have the disease progress; and for those with active periodontal disease to become, and remain, stable.
Until next time, keep flossing!
