3 Mohave Community College firmly supports the idea that writing can be used to improve education; students who write in their respective content areas will learn more and retain what they learn better than those who don t. Courses in the core curriculum have been identified as Writing Across the Curriculum courses. Minimum standards for the Writing Across the Curriculum component are: 1. The writing assignments should total words. For example, a single report which is 1500 words in length OR a series of essay questions and short papers (example: four 375-word assignments) which total 1500 words could meet the requirement. 2. The writing component will represent at least 10% of a student s final grade in the course. Is this course identified as a Writing Across the Curriculum course? Yes X No (See addendum for writing rubrics) Intended Course Goals By the end of the semester, students will be able to: 1. Identify facts regarding the history of dental radiography. 2. Describe the components of x-ray machines and the principles of x-ray production. 3.

C.15 Manage medical emergencies by using professional judgment, providing life support and utilizing required CPR and any specialized training or knowledge. Competency 2 Health Promotion and Disease Prevention (HP) is a key component of health care. Changes within the health care environment require the allied dental professional to have a general knowledge of wellness, health determinants and characteristics of various patient or client communities. HP.1 Promote positive values of overall health and wellness to the public and organizations within and outside the profession. HP.2 Respect goals, values, beliefs and preferences of all patients or clients HP.3 Refer patients or clients that may have physiologic, psychological or social problems for comprehensive evaluation. HP.4 Identify individual and population risk factors and develop strategies that promote health related quality of life. HP.5 Evaluate factors that can be used to promote patient or client adherence to disease prevention or health maintenance strategies. HP.6 Utilize methods that ensure the health and safety of the patient or client and the oral health professional in the delivery of care. Competency 3 Community (CM): Allied dental professionals must appreciate their roles as health professionals at the local, state and national levels. While the scope of these roles will vary depending on the discipline, the allied health dental professional must be prepared to influence others to facilitate access to care and services. CM.1. Assess the oral health needs and services of the community to determine action plans and availability of resources to meet the health care needs. CM.2 Provide screening, referral and educational services that allow patients or clients to access the resources of the health care system. CM.3 Provide community oral health services in a variety of settings CM.4 Facilitate patient or client access to oral health services by influencing individuals or organizations for the provision of oral health care.

CM.7 Advocate for effective oral health care for underserved populations. Competency 4 Patient/Client Care (PC): The three primary allied dental professionals have different roles regarding patient or client care. These are reflected in the competencies presented for each discipline. The roles of the allied dental disciplines in patient or client care are ever changing, yet central to the maintenance of health. Allied dental graduates must use their skills to assess, diagnose (DH), plan, implement and evaluated treatment or services provided. Allied dental personnel must be appropriately educated and credentialed for the patient and client services they provide, and these requirements vary by individual jurisdictions, PC.1 Systematically collect, analyze and record diagnostic data on the general, oral, and psychosocial health status of a variety of patients and clients, using methods consistent with medico-legal principals. PC. 2 Recognize predisposing and etiologic risk factors that require intervention to prevent disease. PC.3 Recognize the relationship between systemic disease, medications, and oral health that impact overall patient or client care and treatment outcomes. PC.4 Identify patients or clients at risk for a medical emergency and manage the patient/client care in a manner that prevents an emergency. Planning PC.5 Select and assemble the appropriate materials and armamentarium for general and specialized patient or client care. PC.6 Collaborate with the patient or client, and other health professionals and indicated, to formulate a comprehensive care plan that is patient or client-centered and based on the nest scientific evidence and professional judgment. Implementation PC.7 Utilize universal infections control guidelines for all clinical procedures. PC.8 Collaboratively manage restorative procedures that preserve tooth structure, replace missing or defective tooth structure, maintain function, are esthetic, and promote soft and hard tissue health. PC.9 Provide clinical supportive and intra-oral treatments within the parameters of general and specialized patient care. PC.10 Prevent, identify and manage medical and dental emergencies. Evaluation PC.11 Evaluate the effectiveness of the provided services and modify as needed. PC.12 Compare actual outcomes to expected outcomes, reevaluating goals, diagnoses and services when expected outcomes are not achieved. Competency 5 Professional Growth and Development (PGD) reflect opportunities that may increase patients or clients access to the oral health care system or may offer ways to influence the profession and the changing health care environment. The allied dental professional must possess transferable skills (e.g., in communication, problem solving, and critical thinking) to take advantage of these opportunities. PGD.1 Pursue career opportunities within health care, industry, education, and research. PGD.2 Develop practice management and marketing strategies to be used in the delivery of
