When a person in is the pre-contemplative stage of change, where are they on the the importance ruler? - correct answer All are basic principles that are encouraged during motivational interviewing EXCEPT: Demonstrate genuine concern and empathy Reflect what the person is saying by paraphrasing Strive to understand the person's situation A tough approach is the best approach - correct answer A tough approach is the best approach What is your task as a health care provider trying to encourage tobacco cessation when the individual is in a pre-contemplation change stage? - correct answer Recommend quitting to the individual When an individual is in the action stage of change, where are they on the importance ruler? - correct answer When an individual is thinking about making a change, what change stage is he/she in? - correct answer contemplation What is your task as a health care provider trying to encourage tobacco cessation when the individual is in a preparation change stage? - correct answer Set a quit date What is your task as a health care provider trying to encourage tobacco cessation when the individual is in a maintenance change stage? - correct answer Identify strategies to prevent relapse The use of reflective listening in motivational interviewing lets the person know that you are listening and understand their point of view. - correct answer True
Knowledge about a habit one needs to change will always be a motivator for that person to change. - correct answer False What is your task as a health care provider trying to encourage tobacco cessation when the individual is in a contemplation change stage? - correct answer Have tobacco user evaluate pros and cons of tobacco use The following are examples of a helpful tobacco cessation professional EXCEPT one: Attempt to understand the person's frame of reference and motivation Affirming person's freedom of choice Provider decides the right time for patient to change Eliciting and reinforcing person's self motivational statements - correct answer Provider decides the right time for patient to change Increasing the power setting on the ultrasonic device increases the displacement amplitude of the tip, shortening the stroke - correct answer False Magnetostrictive devices (cavitron) employ an alternating electromagnetic field which causes magnetization resulting in elongation and contraction and high- frequency oscillation of the insert tip. Which metal is utilized within the Cavitron insert for magnetization to occur when in contact with the copper wire in the hand piece? - correct answer Nickel The magnetostrictive scalers utilized at WVU are 30 kilohertz. Convert these cycle per second (cps) mechanical vibrations to hertz. - correct answer30,000cps There are three operational variables to assess and adjust for effective calculus removal/root debridement/biofilm removal. Match the operational variable tern with the best description/definition. - correct answer power setting : length of oscillating strokes to affect the displacement amplitude of the tip water flow : Cool and maximize cavitation and microstraming activity at the activated tip
Select the best instrument for efficient periodontal therapy in tight grooves and furcation entrances. - correct answer narrow-diameter (slim), curved ultrasonic tip In the past, magnetostrictive scalers were avoided in patients with pace makers, vagus nerve stimulators for epilepsy or on pediatric patients. Modern shielded pacemaker's/vagus nerve stimulator's manufacturers and cardiologists are not concerned of the risk of electromagnetic interference with the function of these devices. On pediatric patients, sensitivity and pulpitis can be avoided by maintaining adequate water irrigation, tip movement with light pressure, and reduced power settings during usage. - correct answer True Select the appropriate sites to assess furcation involvement on mandibular molars. - correct answer mid-buccal, mid-lingual Valid research studies reflect healing following periodontal therapy analyzing the probe depth reduction in sites that were 5mm or greater prior to treatment and ignore the sites that were 4mm or less prior to treatment. This show a true reduction in probing depths rather than an average of healthy sites (<5mm) and unhealthy sites (>5mm) together which can minimize the amount of improvement. - correct answer True Select the reason that mean probing depth calculations for the entire mouth may make the magnitude of probing depth reduction seem less effective following non- surgical periodontal therapy. - correct answer mean probing depths is an average of all pockets in the mouth (4mm). Including the shallow pockets in the average calculation reduces the magnitude of depth reduction that occurred at the sites that were deep prior to treatment.

Which area specific curved tip is appropriately utilized? - correct answer Right Curved A curved insert tip is best utilized when instrumenting the root surfaces of posterior teeth with light calculus and biofilm. - correct answer True What are the four key elements of design of an ultrasonic insert tip that are assessed to make the correct tip selection for effective root debridement? - correct answer profile, geometry, shape, dimension The shape of an ultrasonic insert tip can be either rectangular or circular in cross section. The circular insert tip is more beneficial to the removal of heavy, tenacious calculus. - correct answer The first statement is true. The second statement is false. Ultrasonic Insert Tips that are designed for specifically for safe debridement of dental implants are include: - correct answer Plastic coated Carbon fiber There are three diameters of ultrasonic inserts; standard, slim and ultraslim. Match the name that these 3 diameters are referred to based on their dimension. - correct answer ultraslim : extra-thin tip
standard : traditional or scaling tip slim : thin, modified, micro-ultrasonic or period tip Select the ultrasonic insert tip's diameter that is most efficacious with moderate to heavy calculus removal when it is oscillating against calculus, not root surface. - correct answer Standard The point of an ultrasonic tip exerts a very concentrated output of energy.
