(a)(7) Failing to follow current infection control
recommendations issued by the Federal Centers
for Disease Control or to ensure that auxiliary
personnel and other supervisees follow these
Federal guidelines.
In effect since prior to 2000.
Centers for Disease Control and Prevention (CDC)
3
 Guidelines for Infection Control in Dental
Health Care Settings - - - 2003
 11 years old
So why address now…?
4
 April 18, 2013
 “At least 60 people have tested positive for hepatitis or HIV
after visiting an Oklahoma dentist slammed by the state dental
board for poor sterilization practices, the Tulsa Health
Department said today.”
 A surprise inspection of [the dentist’s] practice on March 18
was prompted by a patient’s positive test…revealed the use of
old needles and rusty instruments.
Since then…
5
 At least three Pennsylvania dentists have been disciplined.
 At least one family practice doctor and a group practice have
been disciplined.
 At the State Dental Board meeting September 5, 2014, two
consent agreements were presented to the Board for
consideration.
 Incidents usually produce a great deal of publicity and an
emergency suspension of the practitioner’s license.
CDC Covers a Broad Range of Practices and Procedures
6
 Personnel health elements
 Blood borne pathogens
 Latex hypersensitivity/Contact
Dermatitis
 Hand hygiene
 Environmental infection control
 Personal protective equipment
 Dental unit waterlines
 Sterilization and disinfection
 Training and procedures
In an hour, we hope to:
7
 Highlight the most important aspects of each element
 Help identify potential problem spots in your office
 Provide a tool for training
 Establish a protocol for inspection and recordkeeping
Overriding General Theme Use Standard (universal) Precautions
8
 Hand washing
 Use of gloves, masks, eye protection and gowns
 Patient care equipment (instruments)
 Environmental surfaces (counters)
 Injury prevention
Intended to Prevent the Spread of Organisms
Spread by Blood and also:
9
 Body fluids, secretions and excretions, except sweat
(whether or not they contain blood)
 Non-intact (broken) skin
 Mucus membranes
Personnel Health Elements
10
 Education and training
 Immunizations (strongly recommended)
 Hepatitis B
 Influenza
 Measles
 Mumps
 Rubella
 Varicella-zoster
 Exposure prevention and post-exposure management
 Medical condition management and work-related restrictions
 Health record maintenance
Bloodborne Pathogens Risk Factors
11
 Frequency of infection among patients
 Risk of transmission after a blood exposure (type of
virus) HBV, HCV, HIV
 Type and frequency of blood contact
Characteristics of Percutaneous Injuries in Dental Setting
12
 Reported frequency among general dentists

declining
Caused by burs, syringe needles, other sharps
Occur outside the patient’s mouth
Small amounts of blood
OMS – fracture reductions and procedures
involving wire
Precautions
13
 Use sharps containers
 Self-sheathing needles
 Use instruments instead of fingers to retract or
palpate tissue
 One-handed needle recapping
Post-Exposure Protocol
14
 Education available for health care personnel
 Access to:
 Clinical care
 Post-exposure prophylaxis
 Testing of source
Hand Hygiene
15
 Hands are the most common mode of pathogen
transmission
 Clean:



Visibly dirty
After touching contaminated objects
Before and after each patient treatment
Degrees of Hand Hygiene
16
 Routine hand wash
 Plain soap and water: 15 seconds
 Antiseptic hand wash
 Antimicrobial soap and water: 15 seconds
 Antiseptic hand rub
 Alcohol based hand rubs: until hands are dry
 Surgical antisepsis
 Antimicrobial soap and water: 2-6 minutes (forearms)
 Plain soap and water followed by alcohol-based surgical scrub:
manufacturer’s instructions
Hand Hygiene Other Considerations
17
 Storage
 Alcohol based away from flames
 Do not “top off”
 Keep fingernails short
 Avoid artificial nails or jewelry that may tear gloves
 Consider compatibility between hand lotions and gloves
Personal Protective Equipment
18
 Trying to protect skin and mucus membranes
from splashes or sprays

Remove protective gear when leaving the
treatment area
Types of Protective Materials
19
 Surgical mask or eye protection
OR
 Face shield
Clean reusable face protection between patients
 If soiled, clean and disinfect
 Change masks in between patients (do not wear as
a necklace)

Clothing
20
 Gowns/lab coats
 Should cover personal clothing
 Change if visibly soiled
 Remove before leaving work area
Gloves
21
 Not a replacement for hand washing
 New pair for each patient
 Change if tear noticed
 Do not wash or disinfect for reuse
 Be aware of sensitivity/allergy concerns of both wearer
and patient (health history)
Sterilization and Disinfection
22
 Critical Instruments

Penetrate mucus membranes or contact bone, the
bloodstream or other normally sterile tissues of the mouth
Heat sterilize between uses or use single-use,
disposable devices
 Scalpel blades, periodontal scalers, surgical burs

Semi-Critical Instruments
23
 Contact mucus membranes but do not penetrate
 Heat sterilize or high-level disinfectants
 Dental mirrors, amalgam condensers, dental
handpieces
Non-Critical Instruments and Devices
24
 Contact intact skin
 Use low to intermediate level disinfectant
 X-ray heads, pulse oximeter, blood pressure cuff
Instrument Processing Area
25
 Have a designated area – it helps maintain
integrity of protocol and assists with training
and performance
Receiving, cleaning and decontamination
 Preparation and packaging
 Sterilization
 Storage

Automated Cleaning
26
 Ultrasonic cleaner
 Instrument washer
 Washer-disinfector
Follow manufacturer’s specifications
Manual Cleaning
27
 Soak until ready
 Wear protective materials:
Mask
 Eyewear
 Utility gloves

Preparation and Packaging
28
 Wrap or place critical and semi-critical items in
containers prior to heat sterilization
 Hinged instruments should be opened and unlocked
 Place chemical indicator in package or container
 Use utility gloves
Heat-Based
29
 Autoclaving – steam under pressure
 Dry heat
 Unsaturated chemical vapor (DEP concerns)
 Use FDA approved equipment

Follow manufacturer’s recommendations for equipment,
packaging, loading…
 Dry/cool inside the machine
Unwrapped Instruments
30
 Sterilize unwrapped instruments only if:
1.
They have been thoroughly cleaned and dried
2.
Mechanical monitors are checked and chemical indicators
used for each cycle
3.
Care is given to avoid heat injury
4.
Items transported aseptically to point of use
 Never store critical instruments unwrapped
 Storage of unwrapped semi-critical instruments is
discouraged. If done, should have clear protocol in place
and follow it
Liquid Chemical Sterilant/Disinfectant
31
 Only for heat-sensitive critical and semi-critical devices
 Use only FDA approved material and post-sterilization
steps



Rinse with sterile water
Handle with sterile gloves and dry with sterile towels
Deliver to point of use in aseptic manner
If stored before use, needs to be re-sterilized.
Liquid Chemical Sterilant/Disinfectant Cont’d.
32
 Follow manufacturer specifications as to:
 Dilution
 Immersion time
 Temperature
 Safety precautions must be followed
 Not typically used for critical instruments
 Use discouraged
Other Forms of Sterilization
33
 Low temperature

Not practical for private office setting
 Bead sterilizers – use at your own risk
Sterilization Monitoring
34
 Mechanical
 Cycle time
 Temperature
 Pressure
 Chemical indicators
 Internal indicator should be placed in every package
 External – if internal cannot be seen from outside package
 Manufacturer specifications
Sterilization Monitoring Cont’d.
35
 Biological indicators
 At least weekly
 Every load containing implantable material
 Use a control BI from same lot
 Use BI’s whenever:
 A new type of packaging material or tray is used
 After training new sterilization personnel
 After repair
 After change in loading procedures
What to do if Positive BI
36
 If mechanical and chemical indicators were ok:


If implantable – recall
If not, repeat spore test using same cycle
 If negative and operating procedures were correct, return
sterilizer to service.
 If positive, do not use until inspected and repaired – and three
consecutive empty chamber negative results
 Document results of biological and monitoring sterilization
Storage
37
 Use date or event-related shelf-life practices:
event – torn – wet (still record date)
 Record machine
 Clean, dry, closed environment
 Examine wrapping carefully – if damaged, re-clean,
wrap, sterilize
Environmental Infection Control
38
 Clinical contact surfaces
 High potential for direct contamination from spray,
splatter or hand
 Housekeeping surfaces
 Walls, floors, ceilings, sinks
Everything else Clinical
Cleaning
39
 Use appropriate barrier precautions
 Elbow grease is as important as the disinfection process
 EPA- registered hospital disinfectants – manufacturer
 Do not use chemicals used in sterilization process
Clinical Contact
40
 Surface barriers changed in between patients
OR
 Clean then disinfect using EPA-registered low to
intermediate-level hospital disinfectant
Housekeeping Surfaces
41
 Routinely use soapy water or EPA detergent
 Clean mops and cloths – allow them to dry
 Prepare cleaning and disinfecting solutions daily –
manufacturer
 Avoid carpet – upholstery in treatment areas
Medical Waste
42
 Medical waste – not considered infectious, discard with
regular trash (98-99%)
 Regulated medical waste – potential risk of infection
during handling and disposal (1-2%)




Solid waste soaked with blood or saliva
Extracted teeth
Surgically removed hard or soft tissues
Contaminated sharps
 Biohazard bag – sharps container
