Due to the amount of material to be covered in this course, it is recommended that you read your textbook chapters before lecture in order to familiarize yourself with the material to be covered in lecture. Technology/Media Component: Class is taught via interactive television video. An attempt will be given to give students, at least a 48-hour notice (not including Saturday and Sunday) via their KCTCS of assignment deadlines, exams, etc. Students are ultimately responsible for all tests, assignments, etc. deadlines even if notice is not given since exams are scheduled in the syllabus. Service-Learning:

10 Course Requirements and Evaluation: In order to continue in the DH Program, a final grade of C or better is required. A student who withdraws from, or earns a grade lower than C in a course, WILL BE DROPPED from the program. The lab portion and the lecture portion of the class must be passed independently of each other for an overall passing grade. Lecture: 5 exams worth 100 points each 500 pts. Lab: Techniques (see TASK) 400 pts Assign/Participation & Quizzes Absence will not be tolerated 100 pts. Quizzes are to be expected every class period Final exam: Comprehensive 200 pts. Total 1200 pts Patient Selection: You are responsible for finding your own radiology patients. We realize this is not easy, but it can be done. I suggest friends, family, and children. Your patients, however, must legitimately demonstrate a need for the radiographs in order to be accepted as a radiology patient. Your patients must have an acceptable health history. Since your Full Mouth and Bitewing requirements are graded on the inclusion of root apices and interproximal contacts, your patient should have a full dentition (wisdom teeth may or may not be present). If you choose a patient with missing dentition, there will be an automatic loss of points because the teeth are not present and therefore cannot be graded. It is possible to fail the assignment before starting because of the number of missing teeth. Your lab instructor may opt to disallow a patient for these reasons. The Panoramic patient may have missing teeth but cannot be totally edentulous. Poor patient selection therefore has a direct influence on the grade of the assignment and is therefore part of the assignment. If 1 st molars are missing but 2 nd molars are present, ask the lab instructor. If 2 nd molars are missing, you do not have a good candidate unless 3 rd molars are present. Some lecture exams may be given during lab time as announced in lecture. Lab Portion Lab Grades DAH Dexter Adult BW #1 film #2 digital if avail. Pass/fail You must pass to advance to the next lab. 2. Adult BW Patient 100 pts possible 3. Dexter Adult Full mouth 50 pts 4. Dexter Adult Bisecting Angle Full mouth Pass/fail 5. Adult Full Mouth patient 100 pts possible 6. Adult Full Mouth patient (digital if avail.) 100 pts possible 7. Panorex 50 pts 8. Occlusal 2 films Dexter pass/fail each a. Max. Topographical Ant. Occlusal b. Mand. Cross-sectional Different sites may vary the order and/or add additional activities. Some of these such as learning how the processor works are important for future assignments. Day to day assignments are at the discretion of the lab instructor. However, questions from the lab assignments will be on the written tests and/or quizzes so please note the assignments in the lecture portion of the syllabus. Lab activities will vary from the lab exercises but you will be

11 held responsible for the information in the exercise, not doing the actual lab. Grading Policy: The scale below shows the relationship between your semester percent average and the letter grade you will receive. Slight deviations from this scale are possible if they seem advisable. A= % B= 86-93% C= 78-85% D= Cannot continue in the program with less than a C E= Attendance Policy: Attendance is required at all labs. Part of the time you will be exposing radiographs on manikins or working directly with patients. At other times you will be processing films, evaluating films, getting films graded, completing other lab assignments, etc. Therefore you are expected to be present during all of the hours of lab unless you have been personally excused on an individual basis by the lab instructor. I DO NOT GIVE MAKE- UPS FOR LAB ASSIGNMENTS. If a student is absent, that student will make-up missed assignments during an OPEN LAB period ONLY. A Passing grade in lab and lecture must be made independently of each other. A passing grade must be achieved in lecture before lab is even considered. Failure or an incomplete on any lab will cause a letter grade drop. Failure or incompletes on 2 labs will be failure for lab and thus failure for the course. You must pass lab and you must pass lecture to pass the course. Showing competency and passing the manikin labs must be ACCOMPLISHED BEFORE the actual patient lab may be attempted. After four attempts to pass or at the lab instructor s discretion on the manikin portion or two attempts to pass or at the lab instructor s discretion on a patient lab without passing, the student may apply for remediation with the instructor and travel to the instructor s site for such remediation. Passing the lecture portion of the class is defined as having a 78% average or higher on the 5 tests and final. The other assignments are part of the overall grade but are not considered in this definition. Failure of 3 of the tests or 2 of the tests and the final is considered failure of the lecture portion regardless of the overall average. Passing this class means you are qualified and competent to take radiographs on the public and failing the exam portion means you are not qualified. Remember you must have an overall average of 78% or higher in all aspects of the course as well as a 78% or higher in lab and a 78% or higher in lab or a C to continue in the program overall. Missed Exam Policy: If a make-up exam is necessary, 5% will be automatically deducted. Make-up exams may be a different exam and format. Any missed quiz will result in a score of 0 for that quiz. No make-up quizzes will be allowed. Make-up exams will be given at the discretion of the instructor. It is the students responsibility to contact the instructor for scheduling the make-up exam. Students requiring a makeup exam must contact the instructor and any other appropriate instructor at each site in order to schedule their individual exam. Makeup exams, dates and times, within the makeup week will be assigned to the student by the instructor. If a student fails to contact an instructor in order to make arrangements for a makeup exam the student will receive a zero score for the exam.

12 Telephone policy: Cell phones will not be tolerated in lecture, lab or clinical settings. You will be required to leave your phone in your locker or place them in a basket at the front of the classroom. If your phone is on you will be dismissed from class for the day and participation points will be adjusted. You will also attend a conference with a program faculty member and program coordinator for a documented reprimand. Repeated reprimands could result in dismissal from the program. If you need to be contacted due to an emergency you may be reached at one of the the following numbers; for Prestonsburg , for London ext and for Lexington ext Late Assignment Policy: Withdrawal Policy: A student may withdraw from the class and receive a W grade at any time specified by the printed college guidelines. After the mid-term date through the end of class work (see Academic Calendar), this instructor will allow a student to withdraw only under extenuating circumstances, such as illness, accident, etc. The student must see the instructor Additional information can be found at the following site:

13 Syllabus Quiz (20 points) DAH 135 Oral Radiology 1. I have read and understand and accept the terms of this syllabus. Student's Signature Date Dr. Kathy J. Miller Date True or False 2. Failure to attend and participate in lecture will result in loss of participation points in the class. 3. I understand I am to have the material to be covered in lecture read before lecture and it may be on a quiz even if lecture has not covered it yet. 4. A failure or incomplete on any lab will cause a letter grade drop. 5. Failure or incomplete on any two labs will cause failure of the course. 6. Failure of 3 lecture exams will result in failure of the class 7. There will be 5 tests, each worth 100 points each, a final worth 200 points, labs worth 500 total points, and various other quizzes and assignments worth 400 points total 8. Patient selection has a direct effect on the possible lab scores and should be taken seriously 9. You are responsible for providing your own radiology patients. 10. It is YOUR responsibility to contact the instructor for make-up exams and/or remediation for lab failures.
