Datasets of relative fluorescence units obtained by spectrofluorometric analysis of filter paper samples and air samples from the environment in a dental clinical setting during simulated dental procedures in a mannequin. Fluorescein was used as a tracer, and an air-turbine or electric micromotor handpiece was used to perform a 10-minuite crown preparation on an upper incisor tooth. Medium volume suction was used concurrently.

Datasets of particle counts, temperature, and relative humidity obtained using an optical particle counter under the same conditions.

Micromotor handpieces were used at three speeds: 60,000 rpm (60K); 120,000 rpm (120K); and 200,000 rpm (200k).

Air sampling and particle counting data were obtained at three distances from the source: 0.5 m; 1.5 m; 1.7 m.
