Abstract

"The presence on the dorsal tongue of additional irregularities such as fissures, grooves and the distribution of papillae constitutes a retention area for harbouring bacteria, particularly those that produce sulphur compounds. A protocol to study the morphology of the tongue in a macroscopic way was developed, aimed at better investigating on the relationship between the dorsal surface of the tongue, considered as a microbial ecosystem, and the oral halitosis (1). A patient affected by oral malodour was chosen and included in the study. A picture of his lingual dorsum was taken to show the areas where the coating was visible. Then, an impression with alginate was taken obtaining a replication in plaster and, on the base of this one, a sort of impression tray was modelled utilizing an impression material made of silicone putty. After this, a second impression was taken combining the tray in silicone putty with a silicone material having a very low-light density (using the 2-step double-mix impression technique). The impression obtained was divided and cut with a blade in six parts, according to Winkel Tongue Coated Index (2), and their contour was observed with the stereo-microscope. The images were analysed with the Image J programme, and the parameter considered was the depth among the papillae. The mean measure of this parameter, in the parts where the coating was visible, resulted in a range between 0,25 + 0,019 mm and 0,55 + 0,11 mm. The same measures in the parts where the coating was not visible swung instead in a range between 0,14 + 0,08 mm and 0,23 + 0,07 mm. This new protocol can be considered clinically relevant for the suitable diagnosis and for the personalized treatment of halitosis."
