ABSTRACT
The purpose of the present study was to assess the irrigant penetration and cleaning ability of a new irrigation system, the Clean Jet Endo (Produits Dentaires SA, Switzerland) in comparison to conventional irrigation followed or not by sonic activation. Irrigant penetration was evaluated on resin blocks simulators by measuring the methylene blue absorbance thanks to a UV/visible spectrophotometer and cleaning ability was assessed in an ex vivo experiment according to the debris score in an artificial canal extension before and after the final irrigation protocol. A statistical analysis was carried out in order to highlight the significant differences between the irrigation techniques. Clean Jet Endo permitted to better eliminate the methylene blue into the simulated canals. A significant difference between the 2 techniques was observed in the middle third (p = 0.005) as well as in the apical third (p < 0.2). An additional microscope observation (16X) confirmed that Clean Jet Endo@ usage led to a better penetration of irrigant within the lateral canals of the simulators. Likewise, this irrigating system permitted to better eliminate the debris in the lateral groove than the other techniques. In conclusion, our findings implied the potential of this new irrigation system to enhance root canal debridement and disinfection.

Chez de nombreux patients; le port d'anciennes protheses completes peut etre a l'origine de diverses lesions au niveau de la muqueuse buccale. Ces lesions peuvent etre hyperplasiques; de type epulis fissuratum ou cretes flottantes ou non tumorales telles que la stomatite sous prothetique. Cet article; expose a travers un cas clinique; les demarches therapeutiques des lesions de la fibro-muqueuse; secondaires au port de protheses mal adaptees et ce; en vue d'une rehabilitation prothetique conventionnelle
