DANB Expanded Functions General Dental Assisting - Additional Info Sample Questions

Which of the following calls for impacted extraction?

Correct Answer:
a tooth which is unable to erupt because it is covered with gingival tissue.


impacted tooth extraction is a dental procedure that becomes necessary when a tooth is unable to emerge properly into its expected position. this usually happens because the tooth is obstructed by either another tooth, excessive soft tissue, or bone. normally, teeth should erupt into the oral cavity without significant resistance; however, when an obstruction is present, it can prevent the natural eruption process, necessitating medical intervention.

there are several scenarios that might call for an impacted extraction, but the most relevant one in this context is when a tooth is unable to erupt due to being covered by gingival tissue. this situation typically falls under the category of soft tissue impaction. soft tissue impaction occurs when the tooth has erupted through the bone but not through the gum. this covering of gum tissue over the tooth can be partial or complete, depending on the extent of the impaction.

when a tooth is impacted by soft tissue or bone, it is unable to achieve its proper position in the mouth, which can lead to various dental issues. these issues include pain, infection, damage to adjacent teeth, and complications with biting and chewing. in such cases, the impacted tooth does not naturally resolve without dental intervention and thus requires extraction.

the procedure for extracting an impacted tooth typically involves surgical intervention under conscious sedation. this ensures that the patient is comfortable and pain-free throughout the process. the oral surgeon makes an incision in the gum tissue to expose the tooth and bone if necessary. depending on the complexity of the impaction, the tooth may be removed in small sections to minimize the amount of bone that needs to be removed.

it's important to address impacted teeth promptly as delaying treatment can lead to more severe complications, such as the development of cysts or tumors around the impacted tooth, misalignment of the surrounding teeth, and deterioration of jawbone structure. regular dental check-ups can help in early detection and management of impacted teeth before they become problematic.
