French guidelines for the management of oral lichen planus (excluding pharmacological therapy)

INTRODUCTION

Oral lichen is a chronic inflammatory disease for which diagnostic management and follow-up are heterogeneous given the absence of specific guidelines in France. Our objective was to develop French multidisciplinary guidelines for the management of oral lichen.

MATERIALS AND METHODS

Working groups from the Groupe d'Etude de la Muqueuse Buccale (GEMUB) formulated a list of research questions and the corresponding recommendations according to the "formal consensus" method for developing practice guidelines. These recommendations were submitted to a group of experts and the degree of agreement for each recommendation was assessed by a scoring group.

RESULTS

Twenty-two research questions, divided into 3 themes (nosological classification and initial assessment, induced oral lichenoid lesions, and follow-up) resulted in 22 recommendations. Initial biopsy for histology is recommended in the absence of reticulated lesions. Biopsy for direct immunofluorescence is recommended for ulcerated, erosive, bullous types and for diffuse erythematous gingivitis. Management should include a periodontal and dental check-up, and investigation for extra-oral lesions. Hepatitis C testing is recommended only if risk factors are present. Definitions, triggering factors and the management of "induced oral lichenoid lesions" were clarified. Oral lichen must be monitored by a practitioner familiar with the disease at least once a year, using objective tools.

CONCLUSION

This formalised consensus of multidisciplinary experts provides clinical practice guidelines on the management and monitoring of oral lichen.

Topical hyaluronic acid in the management of oral lichen planus: A comparative study

AIM

Oral lichen planus (OLP) is a chronic mucocutaneous disorder seen in clinical dental practice. Despite the progress in research and advances in knowledge, the successful management of OLP is still difficult to achieve. The aim of the present study was to compare the therapeutic effects of triamcinolone (TA) preparation (0.1%) with hyaluronic acid (HA) preparation (0.2%) in the management of OLP.

METHODS

In total, 40 patients of any age or sex who had symptomatic OLP were selected and randomly divided into two groups. Group I received topical 0.1% TA, and group II received topical 0.2% HA preparation three times per day for a period of 4 weeks. Basement data were recorded for each patient. Patients were evaluated on days 14 and 21, and after completing the course of treatment. The visual analog scale (VAS) was used for evaluating pain and burning sensation, along with an evaluation of the degree of erythema and mean area of the lesion. Data were analyzed by SPSS 17.0 software using Mann-Whitney and t test. P ≤ 0.05 was considered statistically significant.

RESULTS

Our results showed considerable improvement in all of the parameters evaluated. Baseline characteristics, including pain score, size, and clinical characteristics of the lesions, were not different between the two treatment groups. Both TA and HA were found to reduce the VAS score, the degree of erythema, and size of the lesions after treatment.

CONCLUSION

The application of HA is suggested, and is an effective substitute for TA in the treatment of OLP.
