Tooth Enamel Disorder Is a Feature of Kindler EB
TOPLINE:
METHODOLOGY:
- KEB or Kindler syndrome, a genetic skin-blistering disease associated with pathogenic variants in FERMT1, is the rarest type of EB. Early detection and preventive measures can minimize complications, such as gum disease and other oral health issues, that have been reported in patients with KEB.
- Amelogenesis imperfecta is a group of rare genetic developmental conditions characterized by tooth enamel defects and can be associated with hypersensitivity and eruption disturbances in teeth, as well as periodontal conditions.
- Researchers conducted a longitudinal study on 36 patients with KEB (age, 2 weeks to 70 years; 42% female) from two clinics in Germany and Chile from 2003 to 2023, with follow-up times of 1-24 years.
- The primary outcomes were presence of orofacial features, including amelogenesis imperfecta, intraoral wounds, and periodontal disease, and oral squamous cell carcinoma.
TAKEAWAY:
- All 11 patients with information on enamel structure in their records had pitted enamel anomalies (pitted amelogenesis imperfecta), with variable severity.
- Of patients whose enamel could not be analyzed, three had all teeth crowned in their 20s, suggesting enamel defects, and two had all teeth extracted in their teens or 20s, indicating severe periodontal disease.
- The most common orofacial features were periodontal disease (27 of 36 patients), intraoral lesions (16 of 22 patients), angular cheilitis (24 of 33 patients), and cheilitis (22 of 34 patients), gingival overgrowth (17 of 26 patients), microstomia (14 of 25 patients), and vestibular obliteration (8 of 16 patients).
- Oral squamous cell carcinoma was diagnosed at the site of chronic lip lesions in two patients, with lethal outcomes.
IN PRACTICE:
These findings highlight the extent and severity of oral manifestations in KEB, the authors concluded, adding that “oral care is mandatory” in patients with KEB.

This report, led by Susanne Krämer, DDS, MSc, of Medical Faculty and Medical Center, University of Freiburg, Freiburg im Breisgau, Germany, was published online in JAMA Dermatology.
LIMITATIONS:
The small sample size and the retrospective nature of the study could limit its generalizability.
DISCLOSURES:
The authors did not disclose any source of funding. The authors declared no conflicts of interest.
