Infection Control in Dental HealthCare Settings : 

Infection Control in Dental HealthCare Settings Dental Healthcare Personnel (DHCP) can be exposed to pathogenic microorganisms including cytomegalovirus (CMV), HBV, HCV, herpes simplex virus types 1 and 2, HIV, Mycobacterium tuberculosis , staphylococci, streptococci, and other viruses and bacteria that colonize or infect the oral cavity and respiratory tract. These organisms can be transmitted in dental settings through 1) direct contact with blood, oral fluids, or other patient materials; 2) indirect contact with contaminated objects (e.g., instruments, equipment, or environmental surfaces); 3) contact of conjunctival , nasal, or oral mucosa with droplets (e.g., spatter) containing microorganisms generated from an infected person and propelled a short distance (e.g., by coughing, sneezing, or talking); and 4) inhalation of airborne microorganisms that can remain suspended in the air for long periods. Infection through any of these routes requires that all of the following conditions be present: a pathogenic organism of sufficient virulence and in adequate numbers to cause disease a reservoir or source that allows the pathogen to survive and multiply (e.g., blood) a mode of transmission from the source to the host a portal of entry through which the pathogen can enter the host a susceptible host (i.e., one who is not immune). Occurrence of these events provides the chain of infection. Effective infection-control strategies prevent disease transmission by interrupting one or more links in the chain.

Review of Science Related to Dental Infection Control: : 

Review of Science Related to Dental Infection Control: A protective health component for DHCP is an integral part of a dental practice infection-control program. The objectives are to educate DHCP regarding the principles of infection control, identify work-related infection risks, institute preventive measures, and ensure prompt exposure management and medical follow-up. Coordination between the dental practice's infection-control coordinator and other qualified health-care professionals is necessary to provide DHCP with appropriate services. Dental programs in institutional settings, (e.g., hospitals, health centers, and educational institutions) can coordinate with departments that provide personnel health services. However, the majority of dental practices are in ambulatory, private settings that do not have licensed medical staff and facilities to provide complete on-site health service programs. In such settings, the infection-control coordinator should establish programs that arrange for site-specific infection-control services from external health-care facilities and providers before DHCP are placed at risk for exposure. Referral arrangements can be made with qualified health-care professionals in an occupational health program of a hospital, with educational institutions, or with health-care facilities that offer personnel health services.

Bloodborne & Sharps Injury Facts: 

Bloodborne & Sharps Injury Facts CDC estimates ~385,000 sharps injuries annually among hospital-based healthcare personnel* Bloodborne Virus Transmission: Virus Risk from Percutaneous Injury Hepatitis B (HBV) 6% - 30%** Hepatitis C (HCV) Approximately 2% Human immunodeficiency Virus (HIV) .3% The Costs of Sharps Injuries (source patient & employee) : The Average Direct Cost is $3,042 per exposure*** Baseline and Follow-Up Laboratory Testing Labor Costs Associated with Testing & Counseling Cost of Post-Exposure Prophylaxis Lost Time from Work/Lost Productivity Loss of Income Loss of Career Emotional Costs Societal Costs Long-Term Costs * CDC, Division of Healthcare Quality Promotion, 2010 ** Risk applies to unvaccinated workers only: CDC, National Surveillance System for Healthcare Workers, 2004 *** O’Malley, Scott, Gayle, Dekutoski, Foltzer, Lundstrom, et al., 2007 What Devices are Involved in Sharps Injuries? Six Devices Account for 78% of All Injuries : **** Disposable Syringes 30% Suture Needles 20% Winged-Steel Needles 12% Intravenous Catheter Stylets 5% Phlebotomy Needles 3% Scalpels 8% **** CDC, National Surveillance System for Healthcare Workers, June 1995 – December 2003

Double-Gloving During Oral Surgical Procedures: 

Double-Gloving During Oral Surgical Procedures …the majority of studies among HCP and DHCP have demonstrated a lower frequency of inner glove perforation and visible blood on the surgeon's hands when double gloves are worn. In one study evaluating double gloves during oral surgical and dental hygiene procedures, the perforation of outer latex gloves was greater during longer procedures (i.e., >45 minutes), with the highest rate (10%) of perforation occurring during oral surgery procedures. Based on these studies, double gloving might provide additional protection from occupational blood contact. Double gloving does not appear to substantially reduce either manual dexterity or tactile sensitivity. Additional protection might also be provided by specialty products (e.g., orthopedic surgical gloves and glove liners). Source: CDC, Morbidity and Mortality Weekly Report, 2003
