PMR in dentistry stands for Periodontal Maintenance Recall, which is essentially maintenance cleaning specifically for patients with a history of gum disease (periodontitis) following initial treatment such as scaling and root planing.
Understanding Periodontal Maintenance Recall (PMR)
PMR is crucial for managing and preventing the recurrence of periodontitis. After a patient undergoes scaling and root planing (deep cleaning) to remove plaque and tartar from below the gum line, they enter a maintenance phase. This is where PMR becomes essential.
Key Aspects of PMR:
-
Follows Initial Treatment: PMR is always performed after scaling and root planing or other active periodontal therapy. It's not a substitute for initial treatment.
-
Regular Intervals: A dentist or dental hygienist typically performs PMR every three to four months. The frequency depends on the severity of the initial gum disease and the patient's individual needs and response to treatment.
-
Purpose: The goal is to disrupt and remove plaque and tartar buildup before it causes further damage to the gums and supporting bone. This is especially important because patients who have had periodontitis are more susceptible to recurrence.
-
What it Includes: A PMR appointment typically includes:
- Review of medical and dental history: To identify any changes that may affect periodontal health.
- Examination of the gums: Checking for inflammation, bleeding, and pocket depths.
- Assessment of plaque and tartar: Determining the amount of buildup.
- Scaling and root planing (if needed): Removal of plaque and tartar, both above and below the gum line. While the initial deep cleaning is more extensive, PMR cleanings address new buildup.
- Polishing: To smooth the teeth surfaces.
- Oral hygiene instructions: Reinforcement of proper brushing and flossing techniques.
- Assessment of oral hygiene: Evaluation of the patient's home care effectiveness.
- X-rays (periodically): To monitor bone levels and detect any changes.
-
Why it's important: Periodontitis is a chronic disease, meaning it can be managed but not necessarily cured. PMR helps to:
- Prevent disease recurrence.
- Maintain attachment levels (the connection between the gums and teeth).
- Control inflammation.
- Prevent tooth loss.
- Improve overall oral health.
Difference between PMR and Regular Cleaning:
While both involve removing plaque and tartar, PMR is distinct from a regular dental cleaning (prophylaxis) in several key ways:
| Feature | Regular Cleaning (Prophylaxis) | Periodontal Maintenance Recall (PMR) |
|---|---|---|
| Patient Status | Healthy gums or gingivitis only | History of periodontitis |
| Cleaning Depth | Primarily above the gum line | Both above and below the gum line |
| Focus | Preventative | Managing existing disease & preventing recurrence |
| Frequency | Typically every six months | Typically every three to four months |
| Instrumentation | Standard scaling instruments | Specialized periodontal instruments often used |
In summary, Periodontal Maintenance Recall is a vital component of long-term periodontal care, aimed at preserving oral health in patients with a history of gum disease. It is a specialized cleaning and maintenance program that goes beyond a routine dental cleaning.
