The improvement of a dental syringe includes the addition of a fluid control block. The fluid control block includes a barrel portion having a first connector for attachment to a syringe handle and a second connector for attachment to a delivery nozzle. The barrel portion defines a flow passage. A dial is rotatably mounted to the barrel portion and defines a plurality of differently sized flow orifices alignable one-at-a-time with the flow passage. Each of the flow orifices allows a predetermined level of fluid flow through the flow passage when aligned with the flow passage. The improved dental syringe can be employed to assess abfraction forces acting upon teeth, to assess the success or failure of an occlusal adjustment procedure, and to reduce splatter.
