Exam Plan are you ready

Create a DANB's IS Study Plan

  1. Review exam requirements: Check the Dental Assisting National Board's requirements for the DANB's Isolation exam to make sure your studying approach suits the exam's format and content.

  2. Identify your learning style: Everyone learns differently, and most of us learn best when we get the same information in a variety of delivery methods. Identify the learning styles and studying approaches that best work for you to maximize your study efforts.

  3. Create a study schedule: Set aside dedicated study time each week to ensure you're making consistent progress. You might consider having dedicated sessions for each content area, such as a day or week dedicated to different sections of the exam. Plan to take practice tests at regular intervals to chart your progress.

  4. Take DANB's Isolation practice tests: Practice exams will give you an idea of the types and format of questions that you can expect on test day. Our practice tests replicate the DANB's IS exam format, with 60 unique question on each practice test. By getting you comfortable with test-taking and getting the most out of your practice tests, our practice tests can help you ace your exam on test day.

General DANB's Isolation Study Tips

  • Find a study partner: Do you have a colleague, classmate, or friend who is also pursuing a DANB's Isolation certification? Studying with a partner can help keep you accountable and provide an opportunity for discussion and clarification. Practicing test questions together might be an opportunity for some friendly competition too!

  • Take breaks: Regular breaks can help prevent burnout and improve retention of information. As you study, give yourself regular pauses to decompress and process what you are learning.

  • Stay organized: Keep your notes, study materials, and practice exams organized to avoid feeling overwhelmed. Whether you prefer a physical or digital studying environment (for instance, taking notes by hand versus typing them into your Notes app), a tidy space and methodical approach will help you stay focused on your test prep.

  • Take care of your physical health: A healthy body leads to a healthy mind, so make sure your test prep routine also prioritizes exercise, nutrition, and sleep during your study period. During the lead-up to your DANB's IS test day, don't cram - get plenty of rest so your brain is sharp!

  • Utilize test-taking strategies: Techniques, like the process of elimination, can help improve your chances of success. If you are stuck on a difficult practice exam question, try to rule out one or two options to narrow down the possible answer. Exam Edge's test-taking system allows you to flag practice test questions you want to return to - use these features to your advantage!
By incorporating these study tips into your preparation process, you will be well on your way to success with the DANB's IS exam. Remember, success requires dedication and hard work - don't give up!

DANB's Isolation - Study Plan Tips Sample Questions

Which of the following is NOT a beneficial characteristic of utilizing a dental dam? 





Correct Answer:
eliminates the need for any suction to be utilized


when discussing the use of a dental dam during dental procedures, it is important to understand both the benefits and limitations associated with its use. the dental dam is a thin sheet of latex or nitrile used to isolate the operative site (one or more teeth) from the rest of the mouth. this isolation is crucial for several reasons, primarily involving safety and cleanliness.

one key benefit of using a dental dam is that it protects the patient's oral cavity from contact with debris, dental materials, and infectious materials potentially emanating from an infected tooth. this is particularly important during procedures such as root canals, where the risk of infection or contamination is high. additionally, the dental dam helps in protecting the tooth being worked on from contamination by saliva or other debris. this ensures that the treatment area remains as sterile as possible, which is crucial for the success of many dental treatments.

furthermore, the dental dam provides the highest level of moisture control. by isolating the tooth from the rest of the mouth, it prevents saliva from interfering with dental materials such as adhesives, resins, or cements that require a dry environment to work effectively. this isolation helps in achieving better results and prolongs the durability of dental restorations.

however, contrary to one of the statements in the question, the use of a dental dam does not eliminate the need for suction. in fact, when utilizing a dental dam, it is still necessary to employ both the saliva ejector and the high-volume evacuator (hve). the saliva ejector is used to remove any accumulating saliva from beneath the dental dam. meanwhile, the hve is crucial during procedures involving high-speed handpieces, as it helps in reducing aerosol contamination—a significant concern in the spread of infectious diseases, especially post the covid-19 pandemic.

thus, the statement that the dental dam "eliminates the need for any suction to be utilized" is incorrect and is not a beneficial characteristic of utilizing a dental dam. suction remains a vital component during dental procedures to ensure that the field remains clear and to maintain a high standard of infection control.

Which of the following identifies how a sectional matrix is retained? 





Correct Answer:
retained with a tension ring


a sectional matrix system is a dental tool used primarily in restorative dentistry, particularly when working on interproximal cavities or when placing composite restorations in posterior teeth. the purpose of the sectional matrix is to recreate the natural anatomy of the tooth once the cavity has been filled. this ensures that the restored tooth has proper contact with its neighboring teeth, which is crucial for functional and aesthetic reasons.

to effectively use a sectional matrix, it must be properly retained around the tooth. this is typically achieved using a tension ring, also known as a separation ring. the tension ring plays a vital role in the sectional matrix system by providing the necessary force to tightly secure the matrix band around the tooth. this ensures that the matrix band adapts closely to the contours of the tooth, creating a tight seal that prevents the filling material from escaping and helps in forming the correct shape of the tooth.

the tension ring is usually made from a resilient material and is designed to fit over the matrix band and the tooth. it exerts a continuous outward force, which tightens the matrix band against the sides of the cavity. this setup not only stabilizes the matrix band during the filling process but also helps in achieving the correct pressure between the teeth, essential for creating tight and anatomically correct contact points between the restored tooth and its neighbors.

other methods, such as using a wedge, floss ligature, or a tofflemire retainer, are also known in dentistry but serve different purposes or are used in different contexts. for example, wedges are typically used to separate the teeth slightly and to seal the matrix band at the gingival margin of the preparation. floss ligatures may be used in anterior teeth where a tension ring might not be suitable. the tofflemire retainer, on the other hand, is generally used with a circumferential matrix band for class ii amalgam restorations and is not typically used with sectional matrix systems.

in conclusion, a sectional matrix is most effectively retained by a tension ring. this method provides the necessary stability and accuracy needed for high-quality restorative dental work, particularly in the posterior teeth where precision and durability of the restoration are critical.
