What’s Ahead? • Caries among Alaska Native children• Alaska’s Dental Health Aides• How can we evaluate the oral health of a
population?• Water fluoridation in Alaska
Caries in Alaska Native Children
Caries in AI/AN Children
Full Mouth Dental Rehabilitation (FMDR)
Dental Therapists: A Definition
• Primary oral health care professionals • Basic clinical dental treatment
and preventive services • Multidisciplinary team
members• Advocate for the needs of
clients• Refer for services beyond the
scope of the dental therapist’s practice.*
*SASKATCHEWAN DENTAL THERAPISTS ASSOCIATION
Alaska’s Dental Health Aides
• Certified by Alaska Community Health Aide Program– Began in 2004 by ANTHC
• Work under supervision of a dentist• 4 levels of training
– Primary aide, expanded, hygienist, therapist• Working in > 40 villages
– 90% are Alaska Natives– 80% working in home village
How to Evaluate the Benefit of Alaska’s Dental Health Aides?
• Basic measures– Number of aides, patients, procedures
• Evaluate certification, training, safety
• Impact on health or dental decay?
Available Dental Caries Data
I.H.S. Basic screening survey• Last survey: 2014• Last published: 2011
• Alaska Basic Screening Survey– Kindergarten and third graders
• Last 2010
• Electronic Dental Records (EDR)• Head Start exams
IHS Oral Health Survey
From Phipps, et al, JPHD, 2012
What we really need is surveillance data
What we really need is surveillance data
Surveillance in Public Health
• Ongoing, systematic collection, analysis and interpretation of health data
• For planning, implementation and evaluation of public health practice
Can We Use Electronic Dental Records for Surveillance?
• Data already collected for clinical use– Less expensive than special studies
• More up-to-date than surveys• More complete than surveys
– All clinic users• Provides local or regional data• Can track patients over time
What can be measured through electronic records?
• Basic descriptive information– Age, sex, residence– Clinic usage, procedures, exams
• Health Outcomes– Decay scores for children of a given age
• Decayed, missing, filled teeth (dmft)– Treated vs. untreated decay– Severe outcomes: full mouth dental
reconstruction

Yukon Kuskokwim Region
• EDR since 2005• Use EDR to calculate dmft scores for
the population – Collaboration with ANTHC, CDC
• Measure impact of programs• In-home piped water service• Water fluoridation• Dental Health Aide Therapist Program

Limitations of electronic dental records
• Using the data requires analysis capacity
• Data quality and completeness dependent on charting practices
Electronic Dental Records
• A tool for evaluating oral health in a population over time to:– Assess interventions– Direct prevention efforts
Water Fluoridation
Healthy Alaskans 2020 (HA2020)
Public health initiative to improve health and ensure health equity25 health priorities• Measureable targets to reach by 2020• Provides strategies and specific actions • Identifies key partners across the state to engage in the
work
HA2020 Dashboard
Water Fluoridation in Alaska
• Alaskan population served with optimally fluoridated water
• 2010: 54.8% US: 72.4%• 2020 Target: 58% US: 79.6%
• Communities that stopped fluoridation– Juneau 2006– Fairbanks 2010– Palmer 2013
• Water fluoridation challenged but continued in– Anchorage 2014, 2017– Bethel 2012– Nome 2012
Next Steps
• Continue to work with EDR to support oral health programs
• Evaluate oral health in communities that stopped water fluoridation
