Summary
Periodontitis patients in supportive periodontal care (SPC) experienced low tooth loss rates. Prognostic systems identified high-risk cases, but their accuracy for predicting tooth loss needs improvement.
Area of Science:
- Periodontology
- Dental Public Health
- Clinical Periodontics
Background:
- Periodontitis management requires long-term supportive periodontal care (SPC).
- Predicting tooth loss risk in periodontitis patients is crucial for treatment planning.
- Understanding factors influencing tooth loss during SPC is essential for patient outcomes.
Purpose of the Study:
- To evaluate periodontal stability in patients undergoing supportive periodontal care (SPC).
- To identify tooth- and patient-related factors associated with tooth loss during SPC.
- To assess the efficacy of prognostic systems in predicting tooth loss.
Main Methods:
- A prospective observational study followed 143 previously treated periodontitis patients for 5 years in SPC.
- Periodontal Risk Assessment (PRA) scoring was used to categorize patients into low, moderate, and high-risk groups at baseline.
- Tooth loss rates and associated factors were analyzed.
Main Results:
- The overall annual tooth loss rate was low (0.07 teeth/patient/year).
- Older age, smoking, and disease staging/grading were linked to increased tooth loss.
- Most extracted teeth were from patients in the PRA high-risk group.
- Prognostic systems showed high negative but low positive predictive value for tooth loss.
Conclusions:
- Periodontitis patients in SPC demonstrate low tooth loss rates in private practice settings.
- Prognostic systems can identify high-risk individuals, but their positive predictive value for tooth loss requires enhancement.
- Further refinement of prognostic tools is needed to improve prediction accuracy for tooth loss during SPC.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
