DANB Expanded Functions General Dental Assisting - Features Sample Questions

Which of the following would you choose to open a tooth for restoration?





Correct Answer:
pear shaped bur.


in dentistry, the choice of dental bur is crucial for effectively performing different dental procedures, particularly when it comes to preparing a tooth for restoration or endodontic treatment. the type of bur selected depends on the specific requirements of the procedure, such as cutting efficiency, precision, and the shape of the preparation needed. here, we discuss various types of burs and their typical uses to understand why a particular type may be chosen for opening a tooth for restoration.

firstly, the plain fissure tapered bur is commonly used for creating initial entry into the tooth and extending cavity preparations. its design allows for a smooth, tapered cut that widens gradually, which is ideal for general cavity shaping. however, when it comes to opening a tooth specifically for restoration purposes, this type of bur may not always be the most efficient, especially if precise contouring of the cavity walls is required.

the pear-shaped bur, on the other hand, is particularly well-suited for opening teeth for restorative treatments. its shape allows for excellent access and visibility within the cavity. the rounded, tapered end of the pear-shaped bur is ideal for removing carious tooth material and creating a smooth, rounded internal outline of the cavity. this is crucial in ensuring that the filling material adheres well and that all parts of the diseased or decayed material are effectively removed.

inverted cone burs are another option and are typically used for creating retention in the floors of cavity preparations and in establishing sharp internal line angles. while useful for certain aspects of cavity preparation, their design can be less efficient for the initial opening of a tooth for a restoration, as they might create too sharp angles which are not generally desired in initial cavity preparations.

finally, cross cut fissure straight burs are excellent for rapid cutting and extending straight walls of cavity preparations. they are particularly useful when a flat, smooth wall is needed. however, similar to plain fissure burs, they may not be as efficient as pear-shaped burs in providing the necessary contouring of cavity walls for restorative procedures.

given these considerations, for the specific task of opening a tooth for restoration, pear-shaped burs are generally the preferred choice. they provide the necessary precision and shape for effective cavity preparation that facilitates subsequent restorative treatment. the pear-shaped bur’s design helps in creating a cavity that is conducive to both the effective removal of decay and the successful placement and retention of the restoration material.

The lip bumper is used for:





Correct Answer:
expanding the mandibular arch.


a lip bumper is an orthodontic appliance primarily used for expanding the mandibular arch. this expansion is crucial for creating more space within the lower dental arch, which is often necessary when there is crowding or alignment issues among the teeth. the device effectively utilizes the natural forces exerted by the lower lip, redirecting them to create space and expand the arch.

the lip bumper is designed with a wire that extends from one molar to the other across the inside of the lower teeth. this wire is cushioned by a plastic or acrylic shield that rests against the inner surface of the lips and cheeks. when the lip and cheek muscles push against this shield, the force is transferred to the wire, which in turn applies a gentle outward pressure on the molars. this pressure helps in pushing the molars backward, thereby increasing the space available in the dental arch.

contrary to some beliefs, the lip bumper is not typically used for shifting the midline or aligning the central axis of the teeth directly. its primary role is in arch development. this expansion can indirectly assist in better alignment and spacing of the teeth, as increased arch space allows for easier adjustments of tooth positioning in other orthodontic treatments.

additionally, the lip bumper is not directly involved in closing spaces between teeth. while it does help in creating overall space within the lower arch, the closing of individual gaps between teeth typically requires other orthodontic tools and techniques, such as braces or aligners, which can apply more targeted pressure to specific areas.

in summary, the main function of a lip bumper is to expand the mandibular arch. this is achieved by harnessing the natural muscular forces from the lip and cheek area to exert pressure on the molars, pushing them backward and thereby increasing space within the lower jaw. this expanded space can then facilitate other orthodontic treatments aimed at correcting malpositions and aligning the teeth properly within the newly augmented arch.
