It literally means "bad" occlusion or deviation from the ideal

What is malocclusion?

100

Bleeding and inflammation of the gingiva with NO bone loss

What is gingivitis?

100

The alveolus is lined with this thin layer of compact bone that can be seen on a radiograph.

What is the lamina dura?

100

A rhomboid shaped tooth with an oblique and transverse ridge on its occlusal surface.

What is the maxillary first molar

100

This gland is the largest salivary gland in the mouth, but only supplies about 25% of the total saliva volume.

What is the parotid gland

200

The amount of horizontal overlap between the mandibular incisors and the maxillary incisors

What is overjet?

200

A radiograph reveals furcation involvement of all the molars and probing depths of 6mms throughout the patient's mouth, with 10 teeth lost to disease. The dental hygienist tells the patient they have this perio staging.

What is Stage IV?

200

This band of tissue is at the most apical portion of the gingival sulcus. It attaches gingiva to cementum with specialized cell junctions.

What is junctional epithelium

200

This molar has 5 cusps, 3 of which are distal; a distobuccal, a distolingual, and a distal cusp.

What is the mandibular first molar

200

The junction between the hard and soft palate.

What is the vibrating line

300

This term describes the junction of the upper and lower lips at the left and right sides of the mouth

What are the labial commissures

300

An organized layer consisting mainly of microorganisms that adhere to the teeth and contribute to the development of gingival and periodontal diseases.

What is biofilm?

300

We use this term to describe how much bone and gingival support has been lost in our assessment of periodontal diseases.

What is Clinical Attachment Loss

300

These molars are commonly missing, misshaped, or have fused or shortened roots.

What are the third molars

300

This type of ridge is on posterior teeth and extends from a cusp tip toward the depression or sulcus near the middle of the occlusal surface.

What is the triangular ridge.

400

These are mesio-distal ridges or lines on the cervical third of the labial surface of anterior teeth.

What are imbrication lines

400

An area that is lacking the bony covering and allows the root surface to be exposed prematurely

What is dehiscence?

400

A tough outer tissue that is resistant to bacteria, chemicals, thermal, and mechanical irritations.

What is keratinized epithelium

400

This molar will often have a fifth cusp that is located on the mesiolingual surface.

What is the maxillary first molar

400

Continuous spaces that surround the contact areas between adjacent teeth.

What are embrasure spaces

500

These fibers of the PDL, aid in protecting the tooth from side/diagonal pressures or movements in the alveolus.

What are oblique fibers

500

When the gingival margin has moved apically from the cementoenamel junction.

What is recession?

500
This substance in our body creates pigmentation of our skin, gingiva, eyes, and hair. The more of it you have, the darker your tissues become.

What is melanin pigmentation

500

This mandibular molar has a longer trunk and straighter roots are not as splayed out as its neighbor.

What is the mandibular second molar

500

This papillae type is found near the junction of the body and the root of the tongue. It contains numerous taste buds.

What is the circumvallate papillae
