Prerequisite(s): DNHY 3004 , DNHY 3005 , DNHY 3102 . Concurrent enrollment in DNHY 4018 (Clinical Practice III). A study of the rationale, indications and/or contraindications, and utilization techniques for various procedures including pit and fissure sealants, ultrasonic scaling, periodontal scaling and root planning. The concepts of decision making are examined to help students become responsible and account for their actions. Recognition and management of potentially life-threatening emergency situations are reviewed, with in-depth discussion of the etiological and/or precipitating factors, and the possible effects of these factors on the oral tissues. Emphasis is placed on the integration of this information with knowledge obtained in prerequisite courses to further develop critical thinking skills in obtaining comprehensive patient medical histories and development of dental hygiene treatment plans. This course must be taken in conjunction with Clinical Practice III to achieve cognitive, psychomotor, and affective skills in patient care procedures covered.

Fundamentals of Periodontal Instrumentation, 8th Ed. by Nield-Gehrig

MSU Clinic Manual sections will be provided by Dental Hygiene Program


The purpose of this course is to further the student's ability to provide comprehensive dental hygiene care to clinical patients. It will cover the didactic information necessary to enable the student not only to correctly perform various procedures on patients in Clinical Practice III, but to also understand the rationale behind the indications and/or contraindications for the procedures: pit and fissure sealants, periodontal debridement involving powered and manual scaling, and root debridement techniques.


This course will also enable the student to obtain a more comprehensive patient medical history by providing didactic information on various conditions/ diseases, specifically those that can commonly lead to the occurrence of a medical emergency situation in the dental office. Recognition and management of the emergency situation, as well as the etiological and precipitating factors, will be discussed. The concepts of clinician decision making, responsibility, and accountability are examined to assist the student in developing responsibility and accountability for accurate, consistent, and complete documentation for assessment, dental hygiene diagnosis, planning, implementation and evaluation of dental hygiene treatment.




Four examinations, including the senior 3rd Semester Final Exam, will be given for this course. Each exam will be comprehensive from the first class session and each will constitute 20% of the final course grade. Student 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 makeup examinations. Students will be allowed to make up only one (1) exam per semester. This does not include the Senior 3rd Semester Final Exam.


Final Exam:

The Senior 3rd Semester Final Examination will constitute 20% of the final course grade. It is a 4 hour exam which will serve as the combined final exam for each of the courses offered in the 3rd semester of the dental hygiene curriculum; Dental Hygiene 3, Dental Health Education, and Pathology. The exam will consist of two sections:

1.    Approximately 150 multiple choice questions covering the content of the courses listed above (Dental Hygiene 3, Dental Health Education, and Pathology) AND

2.    A case based portion.


The case based portion of the exam (50 to75 items) will incorporate content from ALL dental hygiene courses taken to this point in time. The case based portion will be figured into the final exam as bonus points. This format, rather than individual course final exams will more effectively assess the student’s ability to combine didactic and clinical content, as well as aid in preparing the student for the National Board Dental Hygiene Exam.


Final Exam Grading: Students will receive a grade on Part One based on the 50 multiple choice items pertaining directly to Dental Hygiene 3 content. Points earned on Part Two, case based items pertaining to Dental Hygiene 3, will be added to Part One as bonus points to determine the final exam grade for this course. The values of Part Two items will be determined by the individual course instructor. Therefore, the points earned for Part Two items will vary between courses.


Water bottles, cell phones, hand-held calculators/computers are not allowed in the room during any examination. Possession of any of these items during an exam will be construed as academic dishonestly and will be dealt with accordingly.


Case Presentation Project:

The Senior Case Presentation project will constitute 20% of the final course grade. Students will work in teams of two on this project. Each team will plan, develop and then formally present to the class a case presentation based on one of the team member’s Clinical Practice 3 patients.


The overall project is an integration of two components: 

1. Case Presentation Written Report of (a) Assessment, (b) Treatment plan development & rationale, (c) Patient education and rationale, (d) Treatment provided & rationale, and (e) Assessment of results.


2. Oral Presentation of Case- Groups will verbally present overviews of content listed for #1 to faculty, fellow seniors, and junior students. Depending on the status of the COVID-19 Pandemic groups will either present in person or via recorded methods.


Specific instructions/rubrics for each portion of this project will be passed out and discussed during the first DH 3 class session.


All work on this project MUST conform to the MSU Dental Hygiene Department PRIVACY PRACTICE PROTOCOL. See complete policy Dental Hygiene Department Handbook Section 1.4


Protocol to insure confidentiality regarding a patient’s medical condition, oral health, and records in accordance with the Health Insurance Portability and Accountability Act (HIPAA) 1996. Any breaches in patient confidentiality or privacy may result in disciplinary actions including:

More than two (2) absences for any reason will result in a loss of 5 points from the final course grade for EACH absence over the allowed 2. This includes the lecture and scheduled clinical sessions.


In cases of extreme illness and/or hospitalization, individual decisions may be made. Two (2) tardies will be     the equivalent of one (1) absence. Students must be present for the entire class period to get credit for a class session. Students leaving class early will be counted as absent. 

Note: 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 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.
