Dental Science

Introduction to Dental Science
ANTH 4523

Instructor:  Jerome C. Rose      Office:  Old Main 348     phone:  575-5247

Office Hours:

There will always be a list of open appointment times for at least two days each week posted outside of the Anthropology Office at Old Main 330 by Friday prior to the following week. If you need more time than the 15 minute time slot just put your name down for another slot. You can contact me by e-mail, jcrose@uark.edu , please write “student” in the subject line. Of course, you may always see me in class and set up an appointment. If you call, leave a message with the office because there is no voice mail.

Class Purpose:

Dental Science has been designed to provide you, the student, with a fundamental knowledge of the human dentition including:  morphology, anatomy, embryology, growth and development. For the Predental student, this course will provide a general introduction to the courses taken during the first year of dental school. In fact, the entire course will be covered in dental school in the first three weeks. For the Anthropology students, this course provides the information necessary to begin study of and research on the human dentition.

Course Organization:

The course begins with a study of dental morphology and functional anatomy and then progresses to embryology, histology, and growth. The rationale for this sequence is that, in my opinion, growth and development are easier to understand if this subject is preceded by a firm knowledge of what the teeth look like at maturity. There will be laboratory sessions held in class where we will look at teeth and make clay models. This will be during regular class time, and I will announce model making day the prior class day.

Required Texts:

Dental Model (all teeth articulated in soft simulated gums) I21D-400G from Kilgore International Inc. There are no acceptable substitutions (the bookstore has ordered some for the class).

Daniel J. Chiego, Jr. 2014 Essentials of Oral Histology and Embryology: A Clinical Approach. 4^th Edition. St. Louis, Elsevier (paper). This book can be rented from the bookstore.

Supplies:

You will need to purchase two new packages of plasticine modeling clay (used by children and usually has 4 bars of different colors) and a carving tool such as a knife (check University Bookstore art supplies).

Course requirements:

There will be four examinations of equal weight.  I have scheduled the examinations, but the dates might vary slightly depending on how far we progress in class and the new date will be agreed upon by class vote (majority of those attending) one week before the scheduled date.  The first two tests will consist primarily of pictures of your study teeth with arrows asking you to identify the selected features.

In class, all students will make 4 clay teeth and these will help you do well on the examinations. If you do not make a model, I will take two points away from your four test average final grade for each tooth that you do not make (thus, if you had an 81 average for all tests and would get a B, but you missed making one tooth you would end up with a 79 and a C in the course).  If you make great teeth (try very hard), I will add a total of two points to your average and, thus, your 78 average which is a C for a final grade would become an 80 which is a B.

Class attendance is mandatory by university regulations. Random quizzes designed to help you learn the material will be administered.  A total of 2 points can be earned to add to your four test average by taking all of the quizzes.  Missing a quiz will result in the loss of these 2 points.

Test Make Up Policy:

There are times when an exam must be missed, this must be requested in writing with documentation before the day of the exam and arrangements will be made in writing. If an exam is missed and there is documentation of a legitimate excuse, then a 20 page library research project will be assigned and the grade on this will be used for the missed examination. If an exam is missed and there is no documentation of a legitimate excuse then you will receive a 0 grade for that exam.

Terms:

Apical—the surfaces of a tooth that face towards the apex of the roots

Buccal—the surface of canines, premolars and molars facing the cheeks

Cervix—the meeting point of the crown and root (the CEJ-cement-enamel junction)

Cingulum—broad bulge girdling the cervical one-third of the crown

Contact area—area of contact between two teeth where the mesial and distal surfaces of adjacent teeth abut

Crest—large ridges descending from the apices of cusps or connecting two cusps

Crown—the part of the tooth that projects into the mouth;  coated with enamel

Cusp—pyramidal or cone shaped elevation on the occlusal surface of a tooth with three to four ridges or crests descending from its apex

Cuspid—elevation smaller than a cusp

Cuspule—elevation smaller than a cuspule

Dentine—the tissue that forms the core of the whole tooth

Distal—the surface of all teeth that faces along the dental arcade away from the median sagittal plane

Enamel—the hard coating covering the crown of the tooth

Fissure—a fault resulting from the imperfect joining of two cusps or lobes

Fossa—round depression

Groove—linear, trough-like depression between cusps

Incisal—the cutting edge of incisors and canines (equivalent to occlusal in the teeth that overlap during normal occlusion

Labial—the surfaces of incisors facing the lips

Lingual—the surface of all teeth that faces the tongue

Lobe—large, rounded projections on occlusal surface

Mammelons—rounded prominence (on incisal margins when they first erupt)

Mesial—the surface of all teeth that faces along the dental arcade towards the median sagittal plane

Occlusal—the surface of all teeth that parallels the plane in which upper and lower dentitions meet.  In particular, it is used to describe      the surface of premolars and molars that meets in normal occlusion

Pit—small circular, tightly defined depression on crown

Pulp—the living tissue of the tooth

Ridge—similar to crests, but smaller and less sharply defined

Root—the part of the tooth embedded in the jaws;  coated with cement

Tubercle—small, rounded prominence on surface of tooth

Wear facet—flat, polished surface created by habitual contact between teeth
