A rinse syringe assembly comprising: a cylinder (21) that includes a cylindrical side wall (22) having an inner surface (23) defining a chamber (25) for retaining fluid, an open proximal end (27) and a distal end (28) that includes a distal wall (29) with a tip (31) extending distally therefrom and having a conduit (32) therethrough in fluid communication with said chamber； a plunger (37) including an elongated body part (38) having a proximal end (39) and a distal end (40), a stopper (41) slidably positioned in fluid tight engagement with said inner surface of said cylinder for expelling fluid out of said chamber (25) by the movement of said cap relative to said cylinder, said elongated body part (38) extending outward from said open proximal end of said cylinder； means for moving additional fluid distally in said conduit (32) after completing the rinsing procedure after the distal movement of said plunger (37) with respect to said cylinder (21) has stopped, said means for moving fluid comprise said stopper which includes a distal end (61) having a distal wall (62) and a cavity (59) therein defining an inner surface (60) and a proximal end (58), characterized in that said distal wall is sufficiently flexible to collapse at least partially into said cavity (59) under the pressure of the liquid of a rinse procedure and to return to its original form after completing the rinse procedure to force additional fluid into said duct (32) .Un conjunto de jeringuilla de enjuague que comprende: un cilindro (21) que incluye una pared (22) lateral cilíndrica que tiene una superficie (23) interior que define una cámara (25) para retener fluido, un extremo (27) proximal abierto y un extremo (28) distal que incluye una pared (29) distal con una punta (31) que se extiende distalmente desde la misma y que tiene un conducto (32) a través del mismo en comunicación fluida con dicha cámara； un émbolo (37) que incluye una parte (38) de cuerpo alargado que tiene un extremo (39) proximal y
