Alveolar osteitis, also known as dry socket, results when a normal clot fails to form in the socket of a recently extracted tooth. Since this condition is usually very painful, always consider it a serious emergency.  Pain in fractured teeth usually results from the irritation of the pulp tissue. Additional infor- mation concerning the types of fractures is contained in chapter 6 of the Dental Technician Training Manual, Volume 1, NAVEDTRA 12572. DENTAL RECORD Each service member’s military dental treatment record consists of a Dental Record Jacket, NAVMED 6150/21-30, containing dental treatment forms. The form used to record dental treatment is EZ603A. It is imperative that all forms documenting patient care contain adequate treatment information. Additional information concerning dental forms is contained in chapter 2 of the Dental Technician Training Manual, Volume 2, NAVEDTRA 12573; and chapter 6 of the Manual of the Medical Department, NAVMED P-117. SECTION SUMMARY When dental emergencies occur and dental facilities are not readily available, medical personnel are expected to perform basic emergency dental care. This section has provided basic information on fundamental dental histology and a variety of dental conditions. We also discussed the importance of dental record maintenance and dental forms used by medical personnel. SECTION II PREVENTIVE MEDICINE Prevention and control of disease are considered the most desirable means of maintaining good health. Information included in this overview should provide you with a general knowledge of the principles and practices of the Navy’s Preventive Medicine afloat and ashore. This information is discussed in detail in the Manual of Naval Preventive Medicine, NAVMED P-5010. SANITATION Sanitation is defined as the formulation and application of measures designed to protect (military) public health, and the disposal of waste. The goal of the Navy’s sanitation program is to provide personnel with a clean and healthy work and living environment. Personal Hygiene Because of the close living quarters in the Navy, particularly aboard ships, personal hygiene is of utmost importance: Uncleanliness or disagreeable ordor will surely affect the morale of your shipmates. Disease and other health problems can spread and rapidly affect an entire compartment or division. Good personal hygiene promotes health and prevents disease. You are responsible for presenting health education training programs to the personnel in your unit, including information on the basics of personal hygiene, and proper exercise, sleep, and nutritional requirements. Sanitation of Living Spaces You, as the MDR, perform sanitation inspections and provide recommendations to the commanding officer. The living spaces, their inspection, and living space cleaning and maintenance practices are discussed in detail in the Manual of Preventive Medicine, NAVMED P-5010. HABITABILITY Factors that can effect habitability of working and berthing spaces are air ventilation, heating, and air conditioning. Measurements of thermal stress are used to monitor environmental conditions in which personnel work, live, and exercise. Monitoring environmental conditions is crucial to maintaining a safe environment for personnel. For more detailed information on the items discussed in this section, you should refer to Manual of Naval Preventive Medicine, NAVMED P-5010. VECTOR AND PEST CONTROL A vector is any animal capable of transmitting pathogens or producing human or animal discomfort or injury. Some of the commonly encountered vectors are insects, arthropods (insects with hard, jointed exoskeleton and paired, jointed legs), and rodents. Pests, on the other hand, are organisms (insects, rodents, fungi, bacteria, snakes, etc.) that adversely affect military operations and the well-being of man and animal; attack real property, supplies, and equipment; or are otherwise undesirable.
