A new type of lichenoid reaction on the lips, potentially linked to microorganisms, was compared to oral lichen planus (OLP). Chlorhexidine treatment showed positive results, suggesting a microbial cause for lip lichenoid reactions.

Area of Science:

  • Oral Medicine
  • Dermatology
  • Microbiology

Background:

  • Oral lichenoid reactions (OLR) and oral lichen planus (OLP) are distinct conditions.
  • A novel OLR subtype on the lip mucosa, associated with microorganisms, requires differentiation from OLP.

Purpose of the Study:

  • To compare a new lip mucosal OLR with reticular OLP of the buccal mucosa.
  • To investigate the potential microbial etiology of the lip OLR.

Main Methods:

  • A comparative study involving 25 patients with lip OLR and a matched OLP group.
  • Clinical observation and patient medication history analysis.
  • Assessment of treatment response to chlorhexidine.

Main Results:

  • Both groups had a mean age of 66, with 62% female predominance.

  • Patients with lip OLR were more frequently on polypharmacy (≥3 drugs) and cardiovascular medications.
  • 80% of lip OLR patients treated with chlorhexidine showed lesion improvement, suggesting a microbial link.

    • Conclusions:

    • Lip mucosal lichenoid reactions may be triggered by microbial plaque on anterior teeth.
    • This finding aids in differentiating lip OLR from OLP and suggests targeted treatment approaches.
