Clinical Laboratory Exercises:
All students must perform 2 each of the following injections:
S/U
PSA, MSA, ASA, GP, NP, IA, Buccal, Incisive
Failure to perform all injections satisfactory will result in a 5% reduction of final grade.
Session Attendance (Absence & Tardiness) effects grade (see below).
Session Absence Grading Effects
One percentage point will be deducted from the final course average for each absence for each 50
minutes of a lecture and/or a laboratory session.
Session Tardiness Grading Effects
Students are expected to report to lectures and to laboratories at the assigned time. Accumulated
tardiness will be treated in a manner parallel to absences; thus, for each 50 minutes of lecture
tardiness, one percentage point will be deducted from the course average.
Grade Scale:
93 – 100% = A
85 – 92% = B
77 - 84% = C
70 - 76% = D
Below 69 = F
Note: Students must attain a “C” grade in this course to be eligible for continuance in the Dental
Hygiene Program.

Attendance:
Attendance is mandatory for all classroom, laboratory and clinical instruction. Students must attend
all sessions due to accelerated pace and detailed content present in the course.
Participation: Students are expected to
 prepare and participate during the entire course.
 be organized and on time.
 complete all required assignments.
 demonstrate responsibility as a team player
 adhere to clinical dress code and infection control policies
Outside Study Time: Approximately 2 hours per day is required for studying material.
GENERAL PROCEDURES
Prior to class, students will receive assigned reading, learning activities and a quiz which are to be
completed prior to and submitted no later than Thursday, August 7 at midnight. The class will meet
during the summer for five days and will involve lecture and laboratory. In the laboratory the
students will administer injections of local anesthesia to a laboratory partner. Competency
evaluations will be utilized in the laboratory.
CLASS ATTENDANCE/CONDUCT/DRESS POLICY
General Remarks
Each student is expected to attend all lectures and laboratory sessions. The student is also expected
to prepare for the laboratory by completing the injection study guide(s) specific to that laboratory
session (sample attached). If the study guide is incomplete, it must be completed before the student
is allowed to practice the particular injection technique on a laboratory partner. Also, students are
to prepare for laboratory sessions by providing a sterile armamentarium.
Conduct Dress
The student will follow department guidelines regarding dress for each laboratory session.
DUE DATES/DEADLINES
All competency evaluations, exams, and course requirements must be completed before 5 p.m.,
August 15, 2008.

OLD DOMINION UNIVERSITY
STATEMENT OF STUDENT RESPONSIBILITIES AND ACCOUNTABILITIES
Attendance Due to the unique responsibilities associated with becoming a competent professional
person and provider of health care, and the progressive nature of the curriculum and its importance
to the provision of quality oral health services, attendance and class participation are required.
Should an absence be necessary, the student should contact the course instructor immediately. Only
an excused absence can be made up. A note from a physician, student health center nurse or other
appropriate individual must be submitted to constitute an excused absence. Late arrivals to class are
considered to be unexcused absences. Each unexcused absence will result in a grade penalty of one
percentage point reduction from the final grade.
Make-up exams for unexcused absences will not be given. . Makeup examinations for excused
absences may be given at the ODU Learning Assessment Center on the first Saturday at 8:30AM
following the missed class. Failure to do so will result in a zero on that particular activity.
Meeting Established Deadlines. All course related assignments are to be submitted to the course
instructor on the established due dates. Work submitted after the established deadlines will be
penalized by the grade. Students are encouraged to keep a duplicate copy of all written assignments
submitted. Assignments not handed in by the deadline will be penalized according to the syllabus
Honor Code By attending Old Dominion University you have signed a pledge accepting the
responsibility to abide by the following Honor Code: "We the students of Old Dominion
University, aspire to be honest and forthright in our academic endeavors. Therefore, we will
practice honesty and integrity and be guided by the tenets of the Monarch Creed. We will
meet the challenge to be beyond reproach in our actions and our words. We will conduct
ourselves in a manner that commands the dignity and respect that we also give to others."
This is an institutional policy approved by the Board of Visitors. The University Honor Code
applies to all assignments.
Plagiarism. All academic work submitted to fulfill a course requirement is expected to be result of
each student’s own thought, research and self-expression. A student will have committed
plagiarism if he or she reproduces someone else’s work without acknowledging its source; or if a
source is cited which the student has not cited or used. Examples of plagiarism include: submitting
a research paper obtained from a commercial research service, the Internet, or from another student
as if it were original work; making simple changes to borrowed materials while leaving the
organization, content, or phraseology intact; or copying material from a source, supplying proper
documentation, but leaving out quotation marks. Plagiarism also occurs in a group project if one or
more of the members of the group does none of the group’s work and participates in none of the
group’s activities, but attempts to take credit for the work of the group.
Code of Student Conduct. All students are expected to abide by the Student Code of Conduct as
found in the Old Dominion University Student Handbook and University Catalog.
Students’ papers and projects may be used anonymously for necessary review.
