CASE STUDY #3: Your patient is an international graduate student who is new to the United States and has never had an appointment with a dental hygienist before. They have never experienced the ultrasonic power scaler and are curious about how it works and what it is used for.  They are studying physics and are interested in the technology. Based on the amount of moderate to heavy calculus you choose to start with a standard tip, then follow up with the ultraslim thinsert. The patient asks questions about tip choice, why water is used, is this instrument more effective than hand instruments, among others. Use this information to answer questions for this patient. QUESTION: Why was the ultraslim thinsert not the first insert that you used?

Case Study #5: You are completing a extra/intra oral head and neck exam on your new patient and charting your findings.  Most of the findings are within the normal limits of anatomy, but you have discovered a few areas that you would like to talk with your faculty member. These include a lesion behind the ear, a variation in color of the sclera that you recognize as jaundice/liver issues, and lymph nodes on the right side of the neck that are firm and palpable.

CASE STUDY #2: You are getting ready to see a difficult .3 periodontal maintenance patient. You want to verify that you are using sharp instruments throughout the appointment so you check and sharpen them carefully.  You work carefully during instrumentation to make sure that you are using accurate scaling strokes to avoid incomplete removal of the calculus. Use this information to answer the next 5 questions. QUESTION: How will you position a hand scaling instrument to remove the calculus?

Case Study #3: Your first patient in clinic is a healthy 24 year old with probe depths 1-3mm and tight, resilient tissue. They report that they do not floss and have not had a dental visit in 6 years. They have generalized calculus interproximal and you are using the sickle scalers to access the calculus.  You notice that you don’t have a sharpening card in your cassette, so you begin scaling without sharpening. While you are scaling, you place the instrument at the proper location on each tooth and use light, sweeping, supragingival strokes using your fingers. When your clinic instructor checks your scaling progress, they indicate that you have missed several areas of calculus in the middle of the proximals and have burnished other areas of calculus. In summary, you have not made much progress with your scaling. Use this information to answer the following questions. QUESTION: To what depth should sickles scalers be used to scale calculus on this patient?

CASE STUDY #1: Your patient is a 72 year old man who has had both knees replaced and has a history of heart conditions including hypertension, a heart attack and a triple bypass in 2018.  He is not allergic to any medications and is taking the hypertensive medication Losartan and is on the anti-coagulant medication Warfarin.  His physician wants him to take a pre-medication before dental visits. His vitals with you today are BP: 130/86, pulse 80 and respirations 12.  He says that he has been having some chest pains lately and has scheduled an appointment to see his physician.  During your appointment, he starts to have some pain in the chest.  Using this scenario to answer the next 4 questions. QUESTION: Regarding the Warfarin, what number do you need to ask him about and what range should it be in to safely treat him?
