Course Prerequisites:

Successful completion of the prerequisite courses for the admission to the Program to include 8 semester hours of human anatomy and physiology is required.

 

Course Description:

 

The histology and embryology of oral tissues, gross anatomy of the head and neck, tooth morphology, and individual tooth identification. Emphasis will be placed on clinical considerations of orofacial development and anatomy relevant to dental hygiene assessment and provision of care. The laboratory portion of the course includes manikin and student-partner experiences.

 

Course Rationale:

As an oral health professional, the dental hygienist must be able to recognize normal structures of the head and neck and oral cavity and communicate with patients and colleagues using professional terminology.  Thus, this course establishes the foundation of normal dental anatomy and the surrounding extraoral and intraoral structures to include the embryologic development and related histology of the orofacial structures.  This foundation is necessary for use in assessing oral health and disease, determining appropriate dental hygiene treatment plans, and applying these findings to instrumentation principles.  This course is offered in the first semester of the dental hygiene curriculum and is a prerequisite for continuing into Clinic I – Dental Hygienist and patient care in the spring semester.

 

This course is designed to support the student’s development so that upon graduation the student is competent as defined by the American Dental Association Commission on Dental Accreditation (ADA CODA) and the Department of Dental Hygiene strategic plan as follows:

Teaching MethodsA variety of teaching methods are used to meet the goals of this course.  Information is presented through lecture, guest presentations, group discussion, small group activities, and case studies.  The laboratory component of the course compliments the preclinical laboratory and will occasionally utilize partner and manikin activities.  Lab activities provide an opportunity for the student to link orofacial anatomy theory with preclinical procedures and instrumentation principles.  Text readings; audiovisual aids to include clinical slides, overhead transparencies, PowerPoint presentations, videotapes, DVDs, online sources and teaching models are used to support classroom and laboratory activities.

 

Participation and Instructor Help:  Learning activities in this course are designed to enhance the understanding of the theory of human anatomy and physiology as it relates to the specifics of the head and neck and orofacial complex.  Additionally this course expands to introduce general histology and the embryologic development of the face and oral cavity and tooth development and morphology.  To assist your management of this varied subject matter small group discussions and various other classroom activities will be utilized.  Assigned readings in the text should be done in advance to enhance your understanding of the information and assist you in relating this information to the course activities and discussions.  I anticipate that each of you will ask questions for clarification as needed and contribute your ideas and knowledge to class discussions.  All students are considered mature enough to seek help and assistance from faculty.

 

Course Policies:

 

1. Attendance:

            As an oral health preventive specialist you will be responsible for assessing, treatment planning, and educating your patients.  It is essential that you have the necessary information provided via this course to adequately carry out this responsibility.  Therefore attendance at all class sessions is expected.

 

Even though attendance is expected, it is reasonable to anticipate that you may encounter situations such as illness that will prevent your participation.  Out of courtesy for the Course Director, please call the main Departmental phone number and leave a message regarding your need to be absent.  It is your responsibility to obtain materials and make up classroom work that is missed. 

 

Formal attendance records will not be kept as part of the overall course evaluation.  However, quizzes will be given regularly in order to assist you is keeping up with the course materials.  NO make-up quizzes will be given in the event of an absence.  Extenuating circumstances surrounding an absence will be considered and may require documentation.  If it is determined that an extenuating circumstance existed for an absence, the Course Director may excuse a quiz versus entering a zero for the missed quiz.  An excused quiz will not be calculated into the course quiz average.  For example, if the overall quiz average at the end of the semester was to be based on 10 quizzes, then the student with the excused quiz will have his/her average calculated using 9 quizzes. 

 

Extended absences due to situations such as major medical or other emergencies will be evaluated on an individual basis between the student, Course Coordinator, and Department Chair and will require appropriate documentation.  Extended absences will be managed on a case-to-case basis when determining the student’s further progress in the Dental Hygiene Program. 

 

2. Professionalism:

            Students enrolled in the Dental Hygiene Program will be expected to display professional behavior in the classroom, lab, and clinic throughout the program of study.  Unprofessional behaviors will be identified and students will be counseled accordingly.

 

3. Scholastic dishonesty:

            This course complies with ACC policies regarding the management of scholastic dishonesty and considers academic dishonesty a serious deficiency when assessing professional behaviors.  Academic dishonesty in itself may constitute dismissal from the Program no matter how well the student in performing academically or technically.

 

            "Acts prohibited by the College for which discipline may be administered include scholastic dishonesty, including but not limited to cheating on an exam or quiz, plagiarizing, and unauthorized collaboration with another in preparing outside work. Academic work submitted by students shall be the result of their thought, research or self-expression. Academic work is defined as, but not limited to tests, quizzes, whether taken electronically or on paper; projects, either individual or group; classroom presentations, and homework" source ACC Student Handbook

 

4. Students with disabilities:

            This course complies with ACC policies regarding students with disabilities:

 

            "Each ACC campus offers support services for students with documented physical or psychological disabilities. Students with disabilities must request reasonable accommodations through the Office for Students with Disabilities on the campus where they expect to take the majority of their classes. Students are encouraged to do this three weeks before the start of the semester" source ACC Student Handbook

 

5. Freedom of expression                                

            This course supports the ACC policies regarding freedom of expression in the classroom.

 

            "Each student is strongly encouraged to participate in class. In any classroom situation that includes discussion and critical thinking, there are bound to be many differing viewpoints. These differences enhance the learning experience and create an atmosphere where students and instructors alike will be encouraged to think and learn. On sensitive and volatile topics, students may sometimes disagree not only with each other but also with the instructor. It is expected that faculty and students will respect the views of others when expressed in classroom discussions."
