CDCA Dental Hygiene (ADEX) - Test Reviews Sample Questions

The root of the tooth is held in position by the:

Correct Answer:
alveolar process

the tooth is a complex structure primarily composed of a crown (the part visible above the gum line) and a root (the part embedded in the jawbone). the stability and positioning of the tooth's root are crucial for its function and longevity. one of the key structures responsible for maintaining the position and health of the tooth's root is the alveolar process.

the alveolar process is part of the jawbone specifically adapted to support the teeth. it contains the alveoli, or sockets, into which the roots of the teeth are anchored. this bony ridge is not static; it remodels and adapts throughout a person's life depending on the presence or absence of the teeth it supports. when a tooth is lost, the alveolar process can begin to resorb or diminish, which can affect facial structure and the ability to install dental prostheses like implants or dentures.

several other processes and parts of the jaw are important in the broader context of oral anatomy but do not directly support the tooth's root like the alveolar process does. for instance, the palatal process refers to a part of the maxillary bones that forms the roof of the mouth but is not directly involved in tooth support. similarly, ionomers and coalesced processes, while potentially relevant in other contexts, do not pertain to the physical support of the tooth's root within the jawbone.

in dental anatomy and oral health, understanding the role of the alveolar process is fundamental. it highlights why maintaining good oral hygiene and addressing any dental issues promptly is crucial to prevent bone loss and ensure the longevity of both natural teeth and dental prosthetics. the alveolar process provides the necessary bone support that teeth require to withstand the forces of chewing and other oral functions.

When a radiographer is mounting and viewing the mandibular and maxillary molar radiographs, what landmark can they use to distinguish between the two?

Correct Answer:
the maxillary sinus.

when a radiographer is analyzing radiographs, particularly those pertaining to the oral region, it is crucial to correctly identify the specific areas being examined, such as the mandibular and maxillary molars. the distinction between these two areas is vital for accurate diagnosis and treatment planning. one of the most reliable anatomical landmarks used for this purpose is the maxillary sinus.

the maxillary sinus is a large, pyramidal-shaped cavity within the maxillary bone, located above the upper teeth and below the eyes. it is one of the four paired paranasal sinuses and is the largest sinus in the human body. its prominence and unique location make it an excellent landmark for identifying maxillary molar radiographs. when viewing radiographs, the presence of the maxillary sinus indicates that the image is of the maxilla, not the mandible.

in contrast, radiographs of the mandibular molars will not show the maxillary sinus, as this sinus is exclusive to the maxilla. instead, mandibular molar radiographs might display other landmarks such as the mandibular canal, which houses the inferior alveolar nerve, and the mental foramen. these features are absent in the maxillary radiographs and thus help in distinguishing between the two.

therefore, when mounting and viewing molar radiographs, observing the presence or absence of the maxillary sinus is a definitive method to determine whether the radiographs are of the maxillary or mandibular molars. this identification aids in accurate diagnostic interpretations and subsequent dental treatments. understanding and utilizing these anatomical landmarks are essential skills for a radiographer working in the field of dentistry.
