DTA 1030 - Dental Anatomy
Clock Hours: 35
Delivery Mode
on-ground
Course Description:
This course is to teach basic dental terminology with simple definitions to introductory level dental assisting students. These terms have been selected for the value in enhancing the students’ understanding and level of comprehension of the technical language of dentistry in pre-dental and pre-clinical units of the program. Greater detail regarding the anatomy of the individual teeth is presented with an emphasis on the relation between morphology and function. This constitutes a foundation basic to all units of the dental assisting program.
Student Learning Outcomes:
UNIT #1 BASIC TERMINOLOGY OF TEETH AND PERIDONTIUM
1. Demonstrate identification of primary or permanent teeth by descriptive name and alternative name.
2. Demonstrate identification of primary and permanent teeth utilizing various systems.
a. Universal
b. International
c. Palmers
3. Locate and identify the following oral structures:
a. Palate (hard and soft)
b. Gag reflex
c. Tongue
d. Salivary glands
e. Oral mucosa
f. Attached gingiva
g. Free gingiva
h. Gingival sulcus
i. Mucogingival fold
4. Identify the tissues which surround and support the teeth.
5. Identify and locate the following parts of the tooth: crown, cervix, root, apex, apical foramen
6. Describe the tooth tissues, their location within the tooth and their function: enamel, dentin, pulp, cementum.
7. Recognize how the functions of teeth determine their shape and size.
8. Differentiate between anterior and posterior teeth and, using the proper terminology, name the surfaces.
a. Proximal-mesial and distal
b. Facial-buccal and labial
c. Lingual
d. Occlusal and Incisal
9. Describe location of maxillary and mandibular arches on a text-book diagram.
10. Demonstrate use of each of the terms: arch, quadrant and designate locations within the oral cavity for primary and permanent dentition:
a. Middling
b. Right/Left
c. Superior/Inferior - Upper/Lower
UNIT #2 PRIMARY AND PERMANENT DENTITION
- Name and give the number of each dentition and the eruption sequence.
a. Primary = 20
b. Permanent = 32
c. Mixed:
1. Age
2. Eruptions cycle
2. Label a diagram of the primary and permanent dentition using the descriptive names and/ or Universal numbering system.
3. Identify succedanious and non-succedanous teeth.
4. Describe root resorption of the primary teeth.
5. Discuss premature and delayed eruption, multiple inerupted, embedded, impacted and ankylosed teeth.
UNIT #3 LANDMARKS OF THE TEETH
- Locate and identify the exact area that each tooth may be divided by imaginary lines into thirds.
a. Crown:
1. Cervical
2. Middle
3. Incisal/Occlusal
4. Lingual
5. Middle
6. Labial/Buccal
b. Root:
1. Cervical
2. Middle
3. Apical
- Locate and identify contact area and embrasures on maxillary and mandibular right quadrants.
- Define the terms: right angle and long axis.
- Distinguish between triangular, transverse, cusp, marginal, and oblique ridges.
- Define the following terms: cingulum, concave, convex, fossa, furcation, groove lobes, mamelon, pit , cervical curvatures, cementoenamel junction, dentoenamel junction
- Recognize the geometric outline forms the most representative of tooth shapes.
a. Triangle
b. Trapezoid
c. Rhomboid
UNIT #4 TOOTH IDENTIFICATION AND ANATOMICAL CHARACTERISTICS
- Demonstrate ability to differentiate maxillary right teeth from maxillary left teeth by identifying individual teeth.
- Differentiate maxillary teeth from mandibular teeth by identifying individual teeth.
- Compare the maxillary right 1st and 2 nd molar with the mandibular 1st and 2nd molars.
- Compare the maxillary right 1st and 2nd premolar with the mandibular right 1st premolar.
- Differentiate between the premolars by buccal and lingual cusp height.
- Compare the pulp chambers and canals in shape, size, and number of canals.
- Locate the cusp of Carabelli on a maxillary molar. Identify which molar and describe the location.
