Summary
Psoriasis patients show significantly more bone loss and missing teeth, indicating a higher prevalence of destructive periodontitis compared to healthy individuals. This suggests a link between the skin condition and severe gum disease.
Area of Science:
- Periodontology
- Dermatology
- Immunology
Background:
- Destructive periodontitis is a common bacterial infection.
- Psoriasis is a prevalent inflammatory skin condition.
- Both conditions involve immune system overreactions to microbial factors.
Purpose of the Study:
- To investigate the prevalence of periodontal disease in psoriasis patients.
- To compare periodontal health in psoriasis patients versus controls.
Main Methods:
- 155 psoriasis patients and 155 age/gender-matched controls participated.
- Dental bite-wing X-rays were analyzed for bone loss and tooth loss.
- Bone level and missing teeth were used as endpoints for destructive periodontitis.
Main Results:
- Psoriasis patients had significantly lower radiographic bone levels (p < 0.001).
- Psoriasis patients exhibited a significantly higher number of missing teeth (p < 0.001).
Conclusions:
- Psoriasis patients experience greater bone loss compared to controls.
- The findings suggest a higher prevalence of destructive periodontitis in individuals with psoriasis.
