What level of supervision is required for a Florida licensed Dental Hygienist to perform the scaling and root planing?

The area of dentistry concerned with the diagnosis and nature of the diseases that affect the oral cavity.

The most widely used method of sterilization in a dental office is the moist heat sterilization unit (autoclave or statim). The moist heat sterilization unit requires a longer processing time as compared to the dry heat sterilization unit.

What is the sequence for donning your personal protective equipment (PPE)?

(a).         A 632 nm light enters a liquid from air at an angle of 34° with respect to the normal and is refracted into the liquid at an angle of 28° with respect to the normal.  (i).          What is the angle between the incident rays and the reflected ray?                                                  (1.0 point) (ii).         What is the index of refraction of the liquid?                                                                                       (1.5 points) (iii).        Calculate the speed and frequency of the light in the liquid?                                                                                          (3.0 points) (b).         A 2.0 m tall object is 40 cm in front of a converging lens that has a 20 cm focal length. Determine the position of the image.                                                                                                                                                                                                                      (3.0 points)                                                                                                                                                           

(a).      A driver slows down his 1200 kg car from 90.0 km/h to 13.3 m/s in 15.0 s. What is the force of your car?                       (4.0 points)                                       (b).         A 1.10 kg falcon catches an absent minded 0.160 kg dove from behind in midair. What is their velocity after impact if the falcon’s velocity is initially 20.0 m/s              and the dove’s velocity is 8.00 m/s?                                                                                                 (2.5 points)                                                                                                                                            (c).    A 50.0 g object is thrown vertically up at a speed of 30 m/s. How far from the thrown position will the object go up before falling back down to the original location         (ignore air friction)?                                                                    (1.5 points)
