A clinician is having difficulty keeping the lower shank parallel to the long axis of tooth #3 which has a 6 mm pocket. The clinician is using a Gracey 13/14 curet with a miniature working end and an extended lower shank. Which of the following would MOST LIKELY improve access in this distolingual surface?
a. Use a straight, slim-diameter ultrasonic tip
b. Use a universal curet with an extended shank
c. Use a rigid Gracey curet instead
d. Switching to advanced fulcrum
What is a switch to advanced fulcrum
Rationale: An advanced fulcrum would facilitate maintaining the lower shank parallel to the tooth surface; note that tooth #3 has a deep periodontal pocket, making access more difficult.

A heavy tea drinker just purchased over-the-counter whitening strips to see if her discolored teeth could be whitened. She wants to know if using whitening strips is better than using the professional custom bleaching tray system at home. You want to provide an evidence-based answer (based on a search of the research literature).
Which type of study will provide the BEST evidence to answer the client’s question?
a. Case-control studies
b. Randomized controlled clinical trials
c. In vitro research
d. Case reports
What is b, randomized controlled clinical trials
Randomized controlled clinical trials provide the best evidence for therapy questions because they are carefully planned investigations that observe and measure the effect of a therapy on real clients under controlled conditions, reducing the potential for error and allowing for unbiased comparison between groups. Cause and effect relationships can be determined.
A. Case-control studies are less reliable than randomized controlled trials and relate to individuals who have a specific condition compared with individuals who do not. Cause and effect relationships cannot be established from this type of study.
C. In vitro research is less reliable than randomized controlled trials because it is based on laboratory research, not on individuals. Findings may not be applicable to the real world setting.
D. Case reports are collections of reports on the treatment of individuals; they do not use control groups with which to compare outcomes, so there is no statistical validity.
