Effect of overdentures on the amount of the gingival crevicular fluid flow of the abutment teeth

The amount of GCF flow of the abutments of ten overdenture patients wasstudied and compared with that of control teeth prepared in the same way andleft uncovered on the opposite arches of the same patients. The GCF wascollected using a standardized filter paper placed in the gingival crevice for30 seconds. A gingival fluid meter was used to quantitated the gingival fluidflow. Data were statistically analyzed. The results indicated that theoverdenture increases the amount of GCF flow of the abutment teeth
