Alopecia and Periodontitis: Exploring the Connecting Dots

The review investigates a potential link between alopecia areata (AA) and periodontitis, both involving autoimmune mechanisms and infection foci. It suggests that AA, an autoimmune condition causing hair loss, may be influenced by oral infections like periodontitis, which is characterized by bacterial infection and immune response. Stress is noted as a common exacerbating factor for both conditions. Case reports indicate that treating oral infections can lead to hair regrowth in AA patients, suggesting a connection between oral health and AA. The authors advocate for further research and a multidisciplinary approach to understand this association, recommending dental evaluations for AA patients and calling for long-term clinical trials to establish a definitive diagnosis.
