Course Expectations

Written Exams: 
Either four (4) or five (5) written examinations, including the final, will be given for this course. Changes to the total number of tests may be made as needed at the discretion of the instructor. Each written exam may be comprehensive from the first class session, with the greatest emphasis placed on the new material presented since the previous exam. 

Water bottles, cell phones, calculators or computers are not allowed during examinations.  Possession of any of these devices during an exam will be construed as academic dishonesty and will be dealt with accordingly.

Laboratory Evaluations: 
One lab exam will be given in conjunction with the written exam covering osteology.  It will be a landmark recognition exercise whereby the  students will identify anatomical landmarks of the skull.  This will be counted as a separate test grade.
Laboratory Exercise: 
Students will select the correct natural teeth necessary to utilize in placing pit & fissure sealants, and for practicing amalgam polishing.  After evaluation of selected teeth by the Instructor, they will be mounted  in dental stone*.  Following completion of Dental Anatomy, they will be used in DNHY 3012, Dental Hygiene 3 for instruction and initial practice of the placement of pit and fissure sealants, amalgam polishing, and ultrasonic scaling techniques.  They may also be utilized in DNHY 4032, Dental Hygiene 4 for instruction and initial practice with the prophy jet.

* Selection of appropriate teeth for mounting will be done on the student's own time.  For Fall 2010 requirements, students will select 3 molars and 2 premolars acceptable for placing pit and fissure sealants, . All teeth will be mounted in stone for use in clinical training for sealant placement and amalgam polishing in following semesters of clinical training

Homework Assignments: 
Homework assignments will be given for each chapter of the textbook.  Homework assignments are due on the day that the chapter is begun.  No late papers will be accepted.  It is expected that the student will complete this work in conjunction with reading of the assigned chapters prior to classroom discussion of the topic.  This will facilitate the students capacity for understanding and discussion during the class session(s).  Students are encouraged to register online and utilize the Student Resource site offered in conjunction with the text at:   http:evolve.elsevier.com

As the daily course schedule is subject to change, it should be understood that regardless of the date, whenever a new chapter of study is begun, the homework assignment will be due at the start of that class period.

At the conclusion of the course, all homework sheets will be returned in the folder provided.  Failure to turn in ALL homework sheets will result in an averaged grade of zero for the homework assignments necessary for the final grade computations.

Final Course Evaluation: 
 The lab exercise (teeth selection and mounting) and combined homework grade (homework papers will be averaged for one collective score ) will be averaged together to count as 10% of the final course grade.    The 4 or 5 written exams, inclusive of the final, will be weighted equally and comprise the remaining 90% of the final course grade.   

Students missing an exam due to illness will be allowed to make up the exam on the day of  their return to school.  No grade higher than a 90 will be given for make-up examinations.  Students will be allowed to make up only one (1) exam per semester.  This does not include the Final Exam. 
Lab. Exercise (mounting teeth):                                             Grade = 100   
Homework Papers ( Grades will be averaged):            Final grade =    98
                                                                                             Average = 198 ÷ 2 = 99

Exam 1 = 92        Lab Practical = 86 Test Average = 530 ÷ 6 = 88.33
Exam 2 = 90        Exam 4 = 82
Exam 3 = 86        Final     = 94

To calculate  10%: 99 x 1 = 99
To calculate  90%: 88.33 x 9 = 794.99
794.99 + 99 = 848.99              848.99 ÷ 10 = 84.89      Final Course Grade = 85 / B

GRADING SCALE:   A grade of "C" is required for successful completion of this course.   
 A = 92-100              C = 75-82
 B = 83-91                D = 65-74 (Constitutes Failure of Course in Dental Hygiene)     

During the semester you will be expected to attend a minimum of two (2) professional presentations outside of regularly scheduled dental hygiene courses.  You will develop a portfolio including the following information: 1) certificates of attendance (if provided); 2) dates, locations and hours of attendance; 3) presenter (including all professional titles and certifications); 4) copies of all course notes/materials provided.  This portfolio will continue to be developed as you progress through the Dental Hygiene Program. It is expected that upon successful completion of the requirements of the Dental Hygiene program, and following graduation, this portfolio will provide an accurate assessment of extra-curricular professional development for the individual.   


These collected teeth will be utilized to construct models of quadrants of the mouth.  The models will be used in Dental Anatomy for tooth recognition and identification, as well as in future Dental Hygiene courses as a learning tool for Pit & Fissure Sealant placement and for practice of ultrasonic scaler usage and techniques.

You will be responsible for contacting the dentist(s) of your choice to request their participation in this project.  The office that will be helping you with this assignment should be provided with the following:

1 gallon or half-gallon juice type container with  large opening or  mouth (transparent or semi-transparent  is preferable)

Fill the container(s) provided from ½ to 3/4 full with the following solution:   1 part unscented household bleach to 10 parts water

Teeth presented in formaldehyde will not be accepted!

Ex: 1 cup bleach to                   or                    ½ cup bleach to
       10 cups of water                                        5 cups water

                  The jug/container should be labeled as follows:
Your name
( 940/397-4764)
the above # is for MSU
Midwestern State University
Department of  Dental Hygiene

The label should then be completely covered with tape to prevent accidental spills from causing it to become illegible.

Please remember that you are now representatives of  the MSU Dental Hygiene Dept.  You should approach the office personnel that will be helping you with the utmost courtesy and consideration. At the completion of this course it will be expected that a thank-you note will be sent by you to the people/offices that have helped you to fulfill this project.

Submission Format PolicyNote: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.

Plagiarism Policy Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception. Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters. We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student. We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed. Written and adopted by the 2002-2003 MSU Student Senate.

Students with Disabilities The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. Among other things, this legislation requires that all students with disabilities be guaranteed a learning environment that provides for reasonable accommodation of their disabilities. If you believe you have a disability requiring an accommodation, please contact the Disability Support Services in Room 168 of the Clark Student Center, 397-4140.

Safe Zones Statement The professor considers this classroom to be a place where you will be treated with respect as a human being - regardless of gender, race, ethnicity, national origin, religious affiliation, sexual orientation, political beliefs, age, or ability. Additionally, diversity of thought is appreciated and encouraged, provided you can agree to disagree. It is the professor's expectation that ALL students consider the classroom a safe environment.

Contacting your Instructor All instructors in the Department have voicemail in their offices and MWSU e-mail addresses. Make sure you add your instructor's phone number and e-mail address to both email and cell phone lists of contacts.

Attendance Requirements

Attendance is critical in order to achieve the maximum benefits of this course.  Reviewing notes and the reading assignments without active participation in the course's clinical activities will not permit the student to adequately meet course objectives.  Therefore, MORE THAN 2 ABSENCES FOR ANY REASON WILL RESULT IN THE FINAL COURSE GRADE BEING LOWERED ONE FULL LETTER GRADE.    In cases of extreme illness and/or hospitalization, individual decisions may be made. 

Two (2) tardies will be the equivalent of 1 absence.

Students are responsible for all material presented in lecture as well as assigned reading.  It is the student's responsibility to obtain any handouts or notes missed in class.

Other Policies

Taping of class lectures will be permitted, but ONLY with PRIOR  APPROVAL of instructor.


Cell phone use (texting or verbal) is extremely disruptive to your fellow classmates and to the faculty teaching your course.  Therefore the use of cell phones will not be tolerated, FOR ANY  REASON. If you utilize your cell phone it will be confiscated for the remainder of the scheduled day.  Repeat offenders will be asked to leave the classroom and will be required to meet with the faculty and the chair of the Dental Hygiene Dept.  In case of emergencies, please notify spouses, family and friends to contact you via the program secretary at 397-4764.

Midwestern State University does not discriminate on the basis of an individual's disability and complies with Section 504 and the Americans with Disabilities Act in its admission, accessibility, and employment of individuals in programs and activities.  MSU provides academic accommodations and auxiliary aids to individuals with disabilities, as defined by law, who are otherwise qualified to meet academic employment requirements.  For assistance call (940) 397-4 618 or (940) 397- 4515.

It is the student's responsibility to declare any disabilities.  After declaration, preferably at the beginning of each semester, the student needs to contact individual instructors to determine any reasonable accommodations that may be required.

By enrolling in this course, the student expressly grants MSU a "limited right" in all intellectual property created by the student for the purpose of this course.  The "limited right" shall include but shall not be limited to the right to reproduce the student's work product in order to verify originality and authenticity, and for educational purposes.

The following is excerpted from Clinical Practice of the Dental Hygienist,  9th Ed, by Esther M. Wilkins, Chapter 1: "Each dental hygienist represents the entire profession to the patient being served.  The dental hygienist's expressed or demonstrated attitudes toward dentistry, dental hygiene, and other health professions, as well as toward health services and preventive measures, will affect the subsequent attitude of the patient toward other dental hygienists and dental hygiene care in general."
....."A dental hygienist may be involved in a variety of moral, ethical, and legal situations as part of the daily routine."


All Midwestern State University (MSU) students may legitimately appeal a course grade if: 1) the student has not been evaluated according to the same criteria as his or her classmates, or 2) an error has been made in grading and/or posting (MSU Student Handbook, p. 37).  In addition, the Office of the Dean of Students has the responsibility to enforce standards of conduct for students as outlined in the MSU Student Handbook (p. 70-80).

When enrolled in the college of Health Sciences and Human Services (COHSHS), students are often assigned to community agencies, such as health care facilities, social service agencies, or athletic environments, as part of their academic process.  During these experiences, the student is expected to behave in a manner required of professionals working in this environment.  COHSHS students may also be required to successfully complete a licensing/certification process following graduation.  As a result, students in these programs are often held to a different academic and/or behavioral standard than students in other MSU programs.  For example, students may no be allowed to progress in a program if they have been unsuccessful (D or F) in a certain number of courses in the major.  In these circumstances, COHSHS faculty and administration, all of whom have had similar professional experience, may make decisions which negatively impact students" programmatic progress.

COHSHS students have a right to a review of decisions made by the program faculty, which prevent individuals from progressing in their program in a timely manner.  However, those who participate in the review must understand the context of the professions involved.  Therefore, issues concerning the professional conduct of students in the COHSHS will NOT be brought to the University Grade Committee, but to the COHSHS Student Conduct Appeals Committee.  Specifically, the COHSHS Student Conduct Appeals Committee will review faculty decisions related to:
 • Student conduct in a clinical experience, internship, or other work-related environment that
          negatively impact the student's academic progress.  This conduct may include behavior which is
          prohibited by licensing and/or professional standards or departmental policy.
 • Student removal from a program because of a) professional conduct issues, or b) failure to
          maintain academic standards required specifically by the program*
