Dental Anatomy

What are 5 functions of primary teeth?

one of the functions of primary teeth is to serve as place holders for______________.

spaces between primary teeth that leave room for the jaw to grow, are known as

what are 2 areas where primate spaces are usually found?

true or false. It is very important to let the childs caregiver know about the importance of primary teeth, because they may not know themselves

What might occur if a child loses their primary teeth too early? What is done in this case?

young children have ground down black teeth, usually seen in other cultures. This may be a result of?

When should you first take your child to the dentist? What is a big reason why?

Why are primary teeth more susceptible to decay than secondary teeth?

true or false. Primary teeth have a larger pulp chamber than secondary teeth, thus creating a higher risk for pulpal exposure

In the primary dentition, what are 2 places that early aggressive periodontitis may occur?

bone loss around lower anterior incisors and mandibular 1st molars, and severe gingivitis in primary dentition might indicate what?

How many phases of arch development are there?

This phase occurs when the permanent first molars erupt

Which teeth, and during which phase, add dramatically to the chewing efficiency and jaw development during a period of rapid growth of a child?

during which phase of arch development is the jaw growing the most?

Which teeth, and during which phase, help support the jaws while the primary anterior teeth are being shed and the other permanent teeth are erupting?

true or false. During phase 1 of arch development, primate spaces remain to allow for future space for permanent teeth.

Which phase of arch development occurs with the eruption of the permanent anterior teeth near the midline of the oral cavity, which is usually the the centrals first, than the laterals.

The permanent anterior teeth near the midline of the oral cavity generally erupt lingual to the primary anterior roots, so when do they establish their final location?

What phase of arch development begins when the premolars erupt?

difference in the size mesially to distally between primary molars and permanent premolars; space allows for future former movement of the molars

required to preserve this space if permanent 2nd molars erupt prior to premolars or if a primary molar is lost prematurely

Which phase begins when the canines wedge themselves between the lateral incisors and the first premolars?

During which phase are the contact relations between the teeth established, and the arch is complete from the first molar forward?

2nd molars are erupting and_____________1st molars during the_____________ process.

What is the final phase of arch development that consists of eruption of the 3rd molars?

which phase of arch development never occurs in some people?

___________of the teeth contribute to the maintenance of the teeth within the dental arch

The maxillary arch is__________________occlusally, and the mandibular arch is_____________.

the anterposterior curvature (concave curve) that is produced by the curved alignment of all the teeth (especially evident when viewing the posterior teeth from the buccal side)

curve that results when a frontal section is taken through each set of both maxillary and mandibular molars, the firsts, seconds, then thirds (concave curve on mandible, and convex on maxilla)

Why do the curve of spee and curve of wilson tend to be lost with age?

Angulations of each tooth's root or roots within the alveolar bone are noted when a tooth is bisected by its what?

The angulation of each tooth's root, or roots allows for proper what?

What are 5 curvature functions?

How does the curvature of a tooth help prevent dental disease?

true or false. Curvature of teeth can disperse occlusal trauma, if they don't disperse it correctly it can lead to loose teeth.

How does curvature of teeth protect the gingiva?

The longer you have your teeth, the longer______________________.

prevents food impaction

prevents bacteria and debris build up

anchors teeth

resists traumatic forces

preserves bone support

area where we floss

The area where cusps contact cusps of teeth on the opposite arch (occlusal surfaces)

Which teeth have interproximal contacts at the incisal third?

which teeth have interproximal contacts at the middle third, or more cervical?

Where is the distal interproximal contact of the maxillary canine?

The triangular shaped spaces between teeth, where the interdental papilla are

The space between roots of individual teeth, where the supporting bone is

What is it called when gum tissue in the interproximal space (the interdental papilla) is missing?

spaces between the teeth that are occlusal to the contact areas (above where the col is)

How are dental embrasures named?

Name 4 purposes of embrasures

What characteristic of the teeth keep the gingiva of the tongue, lips, and cheeks stimulated?

What is another name for height of contour?

contact areas help______________the teeth

the curvature of the CEJ/cervicle line is more curved, or higher on the______________

What is one purpose of the curvature of the CEJ or cervical line?

which teeth have a higher CEJ curvature? Anterior or Posterior?

What is a self-cleaning tendency of enamel?

what is a self cleansing tendency of the crown shape?

describe the tooth shapes of the following teeth that help it have self cleansing tendencies:
incisors
canines
premolars

true or false. The tongue and cheek and pits and fissures act as self cleansing tendencies for the teeth as well

How are contours in the teeth protective to the periodontium?

Which is better in restorations, and undercontoured tooth, or overcontoured tooth?
