Radiography Laboratory and Clinic Procedures
USE OF PHYSICAL SPACE
Only assigned students, faculty, staff and patients may be in the radiography area during laboratory or clinic sessions.
Exposure of radiographs is not permitted without faculty approval.
LABORATORY CLEANLINESS AND ORDER
All students, faculty and staff are expected to cooperate in keeping the radiography area clean and orderly.
All students must remain in lab until permission is obtained by bay/course instructor.
All students, faculty and staff assigned to the radiography area must wear a film badge. The badge will be supplied by the school at no cost to the assigned person. An assigned person not wearing a badge may not be admitted to the area.
An assigned person must wear his/her own badge. Another person's badge or dosimeter must never be worn.
The badge must be worn according to manufacturer's instructions.
Film badges will be exchanged by faculty/staff and read bi-monthly. The radiation safety officer will oversee the mailing and distribution of badges, assure notification of individuals who have received any measurable exposure, deletion, and addition of individuals from the monitoring service and maintenance of monitoring file. The radiation safety officer will maintain a log and be responsible for notification and follow-up action or student, faculty, or staff exposure.
All students will be informed of the potential danger of radiation exposure to the human fetus, and all female students will be asked to inform the course instructor-coordinator if they are pregnant or become so during their tenure in a dental health program. A student who is pregnant or becomes so may continue her assigned activities in the radiation area provided the following conditions are met:
* Her physician has given his/her written permission for her to do so.
* She wears a personal and neonatal film badge. Use of an operators lead apron is optional. The neonatal film badge is to be worn underneath the apron at waist or hip level, and the operator film badge is to be worn at the chest level.
A student must satisfactorily complete the appropriate proficiency examination before exposing radiographs using a specified technique on patients. A student is eligible to take a proficiency examination when he/she has completed the prerequisite laboratory project(s).
It is the student's responsibility to assure that he/she has met the prerequisite(s) for eligibility to take the proficiency examination at the assigned time. A student not completing the prerequisite(s) by the assigned time will not be permitted to take the examination, and will be responsible for securing arrangements to take the examination outside of class hours. Such arrangements are at the discretion of the instructor.
A student passing a proficiency examination is considered to be proficient in that technique at the laboratory (preclinical) level, and is eligible to expose radiographs on patients under faculty supervision. A student failing a proficiency examination must re-practice the skill(s) under consideration, and retake the radiographs until they have demonstrated the ability to perform the task to the grade "C" level. If, after repeating the proficiency exam of a lab task the student receives a failing grade, the student will not be allowed to continue on to patient care. All proficiency examinations must be satisfactorily completed by the last day of the semester. There will be no exceptions.
All radiography patients will be scheduled by the Clinic Secretary or an instructor. Dental Hygiene Clinic patients not originally scheduled for radiography procedures are eligible for radiography services, provided a machine is available and the supervising dentist has prescribed the radiographs in writing.
Clinical patient radiography will occur under the same conditions and utilizing the same procedures described in the Radiation Policy of the Dental Health Programs.
All patients are required to wear a lead apron and thyroid collar with the exception of a panoramic radiograph in which only a lead apron will be worn. All radiographs are exposed according to the ALARA (as low as reasonably achievable).
To minimize patient exposure retakes will not be permitted unless it is determined that a radiograph is non-diagnostic. Non-diagnostic radiographs obscure the apices or interproximal areas. Retakes will not be allowed solely to improve mesial/distal placement. For a full series the retake maximum is three. For a bitewing series the retake maximum is two. All retakes will be exposed under direct supervision of a faculty member
Infection control procedures will be the same as those utilized in the dental health programs.
A patient receiving only radiography services must be examined by an instructor prior to and after the procedure.
Faculty, staff and students alike are expected to treat all other persons in the radiography area courteously, to provide the highest quality of service to all patients, to avoid profanity, to be honest at all times, to maintain confidentiality of patient information, to help maintain cleanliness and order, and to provide assistance to others as needed.
