Summary

Periodontitis is an inflammatory pathology that destroys periodontitis and causes tooth loosening. Its high incidence, combined with very high oral and systemic morbidity, places this pathology at the heart of global public health priorities. The current therapeutic management of periodontitis is not satisfactory because it often leads to a stabilization of the disease, marked by frequent recurrences, especially severe forms. Improving the treatment of patients with periodontitis is therefore an essential priority.

If gingival bacterial dysbiosis is a major contributing factor, this model has clinical-biological limitations that suggest that other etiological factors are involved, and worsen the pathology. In particular, the literature provides clear evidence that periodontal lesions are mostly infected with Herpes EBV, CMV and HSV-1 viruses and that periodontal infection with these viruses is very directly correlated with disease progression (severity). In addition, our work provides new cellular and molecular data that demonstrate mechanisms of active EBV infection of cells and periodontal structures, and highlight inflammatory and necrotic effects associated with this infection. Given these observations and the high pathogenicity of herpes viruses, all known to be powerful inflammatory, lytic and immunomodulatory agents, it seems difficult not to evoke a direct etiopathogenic role of these viruses capable of acting synergistically with periodontopathogenic bacteria.

In this context, the use of an antiviral appears as a very attractive therapeutic proposal to effectively treat periodontitis in combination with conventional treatments. This original and innovative proposal can also be easily and quickly validated in a randomized therapeutic trial through the availability of antiviral molecules that are non-toxic and very specific to human herpes viruses that are derivatives of aciclovir.

Conditions

  • Periodontitis Chronic Generalized Severe

Interventions

DRUG

Antiviral treatment with conventional non-surgical treatment

Valaciclovir, a antiviral treatment will be added to the conventional non-surgical treatment of generalized periodontitis. One gram per day will be administered during 28 days.

DRUG

Placebo with conventional non-surgical treatment

Placebo of valaciclovir (same composition, without active substance) will be added to the conventional non-surgical treatment of generalized periodontitis. One gram a day will be administered during 28 days.
