Eugenol ist ein einfaches Molekül, das jedoch viele positive Eigenschaften für Menschen, Tiere und Pflanzen besitzt. Der Wirkungsmechanismus in einigen Fällen ist noch unbekannt. Die von Forschern am meisten begehrte Eigenschaft ist die antibiofilmische Aktivität von Eugenol, die nach wie vor eine hervorragende Alternative zur Verwendung von Antibiotika darstellt. Eugenol wird in verschiedenen Bereichen der Biotechnologie eingesetzt, besitzt eine geringe Toxizität und ist in kommerziellen Mengen relativ leicht erhältlich.

Eugenol is a simple molecule, but it has many beneficial properties for humans, animals and plants. The mechanism of action, in some cases, is still poorly understood. The property most coveted by researchers is eugenol's antibiofilm activity, making it an excellent alternative to antibiotics. Eugenol has many uses in different sectors of biotechnology, is low in toxicity and is readily available in commercial quantities.

The dental medicine unit at the Jebeniana regional hospital at the end of the 2022 fiscal year comprises two dentists, a nurse, a care assistant and a worker. The activity of the unit's dentists consists of consultation days, school outings and Covid-19 vaccination. - During 2022, two major events marked the operation of the dental unit: the reform of a dental chair in February 2022, and the reduction in the number of dentists from 3 to 2 in October 2022. Despite these two unfavorable events, the unit's activity in terms of quantity and quality improved markedly during 2022, with a peak in November.

Dental biofilm is a stable ecosystem in the form of several microbial colonies that modifies the characteristic physiology of the oral mucosa. It's an ecosystem that dynamically replaces dead cells, and its maturity enables it to shape a primitive circulatory system. This system controls the diffusion or expulsion of nutrients or other substances as required by the biofilm. This characteristic gives it the appearance of a living entity with integrity in its own right. Dental biofilm is a dynamic entity, and must therefore be studied in its microbiological context. The means of exploration, especially staining, are still limited. This difficulty, in addition to the differences between environments and individuals within the biofilm, leaves many mechanisms, especially interactive ones, unknown. The bacteriophage viruses and amoebae that exist in dental biofilms are unquantifiable, making it impossible to study the biological interactions of parasitism (bacteriophage viruses - bacteria) and predation (amoebae - bacteria).
