Lab Evaluations:

Each lab evaluation must be completed to the scoring performance or competency indicated on each evaluation form.  No exceptions. You are expected to practice each task a sufficient number of times to achieve the necessary level of proficiency before completing an instructor evaluation. Each evaluation must be completed to the stated level of proficiency by the date specified.  No lab evaluations can be made-up.  Zero points will be given for any missed lab evaluation. Peer evaluations are an important role in the team concept of this program.  The idea is that the peer evaluator has the responsibility to know the material well enough to perform the requested evaluations and be able to give feedback. Many assignments lend themselves to working in pairs or trios.  This is absolutely necessary for clinical and intra-oral procedures.  Even if you have “checked off” your evaluations, someone else may need you to be a patient.  Mutual cooperation is essential and points will be deducted for non-cooperation or poor team work.

Reading Assignments: It is required that all reading assignments be completed before the beginning of lecture. You are responsible for all information presented in the readings even if this material is not discussed in lecture. Due to the volume of course material, independent study is required. Students must come to class prepared to discuss all reading and RAE/homework assignments. Please make note of anything you do not understand for further clarification in class. Participate, Ask Questions and Be Involved RAE/Homework  Assignments: At the beginning of class I will ask you to hand in your assignment. You must be present and fully participate in the group and class conversation to receive credit for these assignments.


Students are expected to attend all sessions of the course in which they are enrolled. Students are expected to be prepared to begin lab on time; they must be prepared with the appropriate dress code regulations and with the appropriate materials or equipment. A student may be dropped from the class when that student’s absences exceed 10% of the total hours of class time; no more than 2 lecture sessions or 2 lab sessions. Refer to the Dental Hygiene Manual.  Unless state or federal law requires the absence be deemed excused; no instructor shall be required to make a distinction between excused and unexcused absences.

For the safety of the students participating as patients in the lab, students missing lab/clinic time, may be required to write a paper on the material missed to demonstrate their knowledge of these materials/procedures before they will be allowed to proceed with student practice in the clinic.

Late Policy

All assignments are due before class on the due date.

TARDINESS:     Please Refer to the Dental Hygiene Manual – Students are expected to be present in the class/clinic/lab at the scheduled beginning time and remain until the end of class/clinic/lab. Quizzes and tests are given at the beginning of class/clinic/lab. If you are tardy to a class/clinic/lab you will have less time to take the scheduled quiz or test.            

The total amount of time tardy or early leaving cannot exceed the 10% attendance maximum. Arriving late for lecture or lab disrupts the instructor and your fellow classmates. Students will not be allowed to enter the class late if it interrupts class instruction, if the door is closed please wait until the instructor opens it at a natural break in the instruction

No late assignments excepted. Consult your instructor of any concerns.


There will be quizzes, midterm and final exams. The material comes from the textbook, class lectures and supplemental materials. If any exam is missed, a zero will be recorded as the score. It is your responsibility to take the online exams by the due date.

Quizzes: NO make-up quizzes, Quiz grades will only count if the student is present for the entire class

Examinations/quizzes are not returned to the student – if you would like to review your exam, please plan to make an appointment to meet me in my office for this review. All exams will be kept until 30 days after the end of the semester and then disposed of appropriately. Note: exam review will not be scheduled in the last week of the semester; please plan to request the review of your exam before this time.

  • Any papers/assignments must be professional in presentation – using professional terminology, correct spelling and grammar, computer generated, neat and organized, computer generated, neat and organized.
  • ALL requirements for this course must be met; failing to meet any requirement will result in a failing grade for the course.
  • The best way to learn is through active participation; therefore, we respect others by being on time, listening actively and by being polite even when we disagree with another’s viewpoint.
  • Electronics devices may be beneficial in the classroom and also distracting when they are used inappropriately. The use of any electronic device; computer, pad, phone and/or watch will only be used for direct class enhancement and/or to refer to information that is presented for this subject. Electronic devices (including watches, will not be allowed during testing)
  • Students are expected to attend all class sessions and be prepared to discuss assigned reading and other assignment at a collegiate and professional level.
  • Professional, self-motivated and cooperative behavior is expected.


All students are encouraged to seek assistance from the course instructor.  If you have any questions concerning assignments, content, etc, or if a problem arises that warrants instructor help, please do not hesitate to schedule an appointment with the lead instructor at your earliest convenience.



Any student achieving less than 75% on a quiz is strongly encouraged to arrange a meeting with the instructor to discuss deficiencies in their grade and arrange potential remediation. 

Practice time and review of models/visuals – the lab will be available for review of models and other visuals on Wednesday at 7:30AM and for 30 minutes immediately following the lecture or by special arrangement with Professor Hellums . Intra-oral student practice in the clinics is not allowed without DIRECT faculty supervision with Professor Hellums.

Standards of Conduct

Students who register in SRJC classes are required to abide by the SRJC Student Conduct Standards. Violation of the Standards is basis for referral to the Vice President of Student Services or dismissal from class or from the College. See the Student Code of Conduct page.

Collaborating on or copying of tests or homework in whole or in part will be considered an act of academic dishonesty and result in a grade of Zero for that test or assignment. I encourage students to share information and ideas, but not their work. See these links on Plagiarism:
SRJC Writing Center Lessons on avoiding plagiarism
SRJC's policy on Academic Integrity

  • Student Conduct - We will conduct ourselves in a manner which reflects our awareness of common standards of decency and the rights of others. All students are expected to know the Student Conduct Policy and adhere to it in this class. Students who violate the code may be suspended from 2 classes and may be referred to the Conduct Dean for discipline.
  • Academic Integrity - All written work is to be original; plagiarism of any kind will result in a failing grade on that assignment. Students who plagiarize or cheat may be suspended – for one or two class meetings by the instructor – and referred to the Conduct Dean for discipline sanction, in cases of egregious violation. Please see Policy 3.11 for Academic Integrity .

Other Important Policies and Practices

Avoid Plagiarism 

Although most students have likely heard about plagiarism during their years of schooling, it still is prevalent-even in higher education.

The video below reviews what plagiarism is and how not to do it.

This activity tests your knowledge of plagiarism (not graded): Self-check: Plagiarism


Netiquette, or Why Is It Harder to Be Polite Online?

Netiquette refers to using common courtesy in online communication. All members of the class are expected to follow netiquette in all course communications. Use these guidelines:

  • Use capital letters sparingly. THEY LOOK LIKE SHOUTING.
  • Forward emails only with a writer's permission.
  • Be considerate of others' feelings and use language carefully.
  • Cite all quotations, references, and sources (otherwise, it is plagiarism).
  • Use humor carefully. It is hard to "read" tone; sometimes humor can be misread as criticism or personal attack. Feel free to use emoticons like :) for a smiley face to let others know you are being humorous.
  • Use complete sentences and standard English grammar to compose posts. Write in proper paragraphs. Review work before submitting it.
  • Text speak, such as "ur" for "your" or "ru" for "are you" etc., is only acceptable when texting.


Santa Rosa Junior College’s Dental Hygiene Program believes that professionalism is an essential component to the development of a health care provider. Our program strives to nurture and develop strong levels of professional behavior. All dental hygiene students are expected to demonstrate professionalism in behavior, communication, patient privacy and judgment in the dental clinics, classrooms, and clinical rotation sites. All clinical and classroom faculty will offer feedback for this development by formal and informal means.  Repetitive instances of non-professional behavior or speech at any time during matriculation in the program will not be tolerated and may result in program dismissal.  

A review of expectations and criteria for Professionalism is found in the Student Handbook 



The dental health care provider is expected to demonstrate empathy in all interactions whether considering peers, patients, faculty or staff. Further the dental hygiene and assisting student must demonstrate respect for and complement the roles of other professionals. Understanding that dentistry is a collaborative effort, the dental health care student must be able to effectively work as a member of a healthcare delivery team. 

Gaining clinical proficiency requires preclinical as well as clinical practice. Preclinical practice is usually accomplished by using manikins and any student partner.

The District does not allow discrimination (District Policy and Procedure 2.7).

ALL students are expected to cooperate and participate fully by working with any student in the programs as both a patient and an operator during preclinical and clinical practice.



Supervision of lab closing duties will be assigned to each student at the end of the lab. This is a part of the class assignment and must be completed before leaving the lab. The lab duties may include organizing and cleaning of the lab/restorative/dental hygiene clinic, sterilization of instruments or other duties as dictated by the lab activities. 

The lab monitor will assign the cleaning/closing duties to each student and as part of their supervision and will be ultimately responsible for the completion of these duties.
