UNE Summer Session

DEN 201: Histology and Embryology – 12 Weeks

Credits - 2

Description

This course is an introduction to oral histology and embryology with an emphasis on those tissues that compose the head,

neck, and oral cavity.

Materials

Learning Objectives and Outcomes

1. Identify the boundaries of the oral cavity and oropharynx and relate the importance of distinction for the purpose of documentation of findings. Be able to identify and label structures of the oral cavity for use in documentation during intra/extra oral exam.

2. Identify, classify, and describe epithelium, connective tissue, cartilage, bone, lymph, muscle and nerve tissue according to cellular and fibrous components and their functional significance.

3. Identify and or/ describe tooth formation: stomodeum and buccopharyngeal membrane, development of dental and vestibular lamina, tooth bud formation, stages of tooth development according to shape (bud, cap, bell), stages of tooth development according to functional activity, cellular components of the dental organ, inner and outer dental epithelium, stellate reticulum, stratum intermedium, dental papilla and dental sac, Hertwig’s root sheath, and primary vs. successional dental lamina.

4. Identify and describe amelogenesis, dentinogenesis, root formation, and cementogenesis.

5. Identify and describe the histological, physical, and chemical characteristics of enamel, dentin, pulp, cementum, periodontal ligament, alveolar bone, oral mucosa and salivary glands and tonsils.
6. Identify the embryologic and histologic factors which promote oral health and help the dental hygienist to recognize pathological oral conditions.

Specific Unit Objectives:

Chapters 3-5

By the time students have completed this unit, they will be able to describe the general concepts of neonatal development, and apply those to the formation of the head, neck, and oral cavity. This unit is critical for the practicing dental professional to understand and promote oral health, and to recognize pathological oral conditions.

Chapters 6, 1-2

By the time the students have finished this unit, they will apply the essential facts and concepts of neonatal development to the development of the teeth specifically (odontogenesis). Furthermore, this unit includes a review of the anatomical components in the mature oral cavity. This unit is critical for the practicing dental professional to understand and promote oral health, and to recognize pathological oral conditions.

Chapters 7-11

By the time the students have completed this unit, they will be able to identify and describe general cellular and tissue structures, with an emphasis on the histology of soft tissues of oral cavity. This unit is critical for the practicing dental professional to understand and promote oral health, and to recognize pathological oral conditions.

Chapters 12-14

By the time the students have completed this unit, they will be able to identify and describe the hard tissues of the oral cavity, particularly the teeth and bones in which they are situated. This unit is critical for the practicing dental professional to understand and promote oral health, and to recognize pathological oral conditions.

Assignments

Reading & Practice

Students are expected to stay up to date in reading and reviewing course material by the start of the week in which it is assigned. Reading assignments are listed in the course calendar and in the weekly modules. The assigned reading is the ultimate  basis for all content delivered in the course.

Additionally, optional (though recommended) practice assignments will be made available to supplement your studies. Where available, any such materials will be pointed out by announcement or within [designated] modules.

Quizzes

Each week, an assigned quiz composed of multiple choice and true/false questions will be assigned for you to express and test your knowledge on the week’s topic. Quizzes will cover specific chapter topics (as laid out in the course calendar and weekly modules). Quizzes are due on Friday nights.

Quiz material is essential as a semi-formative learning experience in preparation for summative exams. Students will receive two attempts at each quiz (where an average of the two scores is kept).

Furthermore, quiz questions will help to form the basis of Discussion assignments (see below).

Discussions

Where listed in the course calendar, your original discussion post is due on Sunday night (within 48 hours after your quiz is due). The instructor will respond to your post within 24 hours, and you must close the loop on that discussion (following up on comments made by the instructor) before you can take your next quiz.

Specific instructions and a rubric will be posted with every Discussion board link.

Exams

There will be three (4) summative exams in this course, one on everythird week. Exams will contain multiple choice and true/false questions only. Exams will at the beginning of the week in which they are scheduled and must be submitted by that Wednesday night.

All prior quizzes and discussions must be completed before any new test is taken.

 

Assignments/Assessments Summary

All assignments are due at 11:59 PM ET on the day they are due

Discussions (8)

• Discussions are in place of class time, and therefore are a critical learning component 
• one initial/original posting is required by Sunday night (unless otherwise noted)
• follow up postings are required to unlock access to your next quiz
  • you must reply to the instructor (and receive a grade) in order to progress to the subsequent quiz for the week
  • a rubric is posted for grading guidelines

Quizzes (8):

• Quizzes assess our knowledge of the material as we go
• Quizzes are semi-summative
  • 3 attempts per Quiz (average of scores is kept)
• Quizzes consist of multiple choice and T/F questions
• Quizzes are due on Fridays nights

Exams (4):

• The course is divided into four (4) three-week intervals
• There is one exam per interval: four exams total
• Exams will follow a similar format to quizzes, however:
  • Only one attempt is allowed
  • Exams require Honor Lock proctoring
• Exams open at the beginning of the week in which they occur, and are due that Wednesday
