Summary

The amoeba Entamoeba gingivalis colonizes the human oral cavity, where it can actively destroy tissue and cause local inflammation. Currently, there is no standard treatment for E. gingivalis infection. Even during treatment for periodontitis, there is no specific treatment targeting E. gingivalis, although this could significantly improve the effectiveness and long-term results of periodontitis therapy. Octenidine is an antiseptic agent used for disinfecting skin, mucous membranes, and wounds. It is effective against bacteria, fungi, and some viruses. octenident® is a commercially available cosmetic mouthwash containing octenidine as the active ingredient. Its efficacy against Entamoeba spp. will be tested in vitro. Because E. gingivalis is very difficult to cultivate under laboratory conditions, and in vitro testing may not be feasible, the effect of using the mouthwash octenident® (cosmetic product) twice daily for 30 seconds over a 7-day period on the quantity of E. gingivalis will be evaluated in healthy volunteers using quantitative real-time PCR, a technique enabling the comparison of E. gingivalis DNA before and after the use of octenident®.

Conditions

  • Parasite Infestation

Interventions

PROCEDURE

saliva and plaque sample collection for analysis

For collection of plaque two different gingival sites are selected for sampling in each participant. Prior to sampling, supragingival plaque is removed with a sterile instrument. Subgingival plaque is then collected from the same site using a sterile Gracey curette. Saliva samples are collected using a commercially available saliva collection kit (Sallivete®, SARSTEDT AG, Germany). Participants should open the Sallivete® tube, remove the synthetic swab, and place it in their mouth for 1-2 minutes, ensuring it moves around to facilitate optimal saliva collection while avoiding chewing.

OTHER

using commercial mouthwash

Participants use the commercial mouthwash octenident (cosmetic) twice daily after their normal dental routine for 30 seconds for consecutive seven days
