Theory of Inflammatory Complications
• Periodontitis contributes to the systemic
inflammatory burden
• The diseases or the treatment for diseases may
suppress immune system
• Suppressed immune system may increase the
risk for periodontal disease and systemic
consequences
Hypothetic model for how peridontitis may act as a potential cause of local and systemic
inflammation in chronic kidney disease patients.

Systemic Disease Treatment
Gram negative bacteria
Products of Infection
Loss of appetite
Dry mouth
Suppressed Immune System
Interaction Effect
Tooth Loss
Other chronic infections
Host response variations
Compromised Nutrition
Full impact of inflammation has not been explained.
Directionality has not been clearly demonstrated.
Take Home Message
Host response to inflammation
may be the
common risk factor for both
periodontal disease
and other chronic diseases
Take Home Message
• Interactions between diseases is more than
additive
• OR
• All of the pieces of the pie add up to a whole
bake sale
Directionality
• Associations are clear, directionality is not
• Perio and then chronic disease
OR
• Chronic disease and then perio?
GDM
• Patients with perio AND GDM were more likely
to develop Type 2 DM than patients with GDM
alone
• Authors hypothesize that periodontal disease
may contribute to impaired glucose metabolism
and future risk of developing diabetes
Perio in Healthy Individuals
• Evidence of impaired metabolic function
increases in the presence of periodontal disease
• In 3 separate studies, patients without diabetes
had higher A1c levels in the presence of
periodontal disease
• Does not prove directionality-but suggests a
common risk factor- Host inflammatory
response?
CVD
• Periodontal disease increased risk for CVD even
after controlling for other known risk factors
▫ Diabetes duration
▫ Hypertension

chronic kidney and periodontal disease: a study using structural equation modeling.

COPD
• Periodontal disease remained a risk factor after
controlling for other know risk factors
▫ Smoking
▫ Environmental Exposures

of chronic obstructive pulmonary disease: a meta-analysis of observational

Pregnancy Outcomes
• Equivocal evidence
• Conflicting results showing association between
periodontal disease and preterm, low birth
weight, and preeclampsia
Summary
• Abundance of evidence of an association
between systemic conditions and periodontal
disease
• Many questions remain
▫ How does the severity of periodontal disease or
the type of treatment impact systemic disease?
▫ Is there a direct relationship or is inflammation
the confounder that affects each condition?
▫ Does treatment for perio reverse improve the
systemic condition?
Perio Treatment Outcomes
• Current research indicates that treatment
improves periodontal health even in the
presence of co-morbidities
• Measures of periodontal health may improve but
inflammation markers may not improve
Reversibility: Impact of Perio
Treatment on Systemic Conditions
• Treat the periodontal disease, reduce the risk of
other diseases or complications?
• Maybe…
Type 2 Diabetes: Moderate-Poorly
Controlled DM (7.5-9.5 A1c)
• Perio Tx: SRP, Exts, antibiotics
• Improved after tx for Moderate Perio

Rheumatoid Arthritis
• Researchers compared RA patients who DID and
DID NOT receive perio treatment
• Periodontal treatment improved RA markers
regardless of drug therapies

Pregnancy
• Meta-analysis of OB outcomes research
• Periodontal treatment did not reduce risk of
preterm or low birth weight babies BUT
• Treatment DID reduce risk of preterm, low birth
weight babies

Implications for Practice
• Knowledge:
▫ How informed are dental and medical
professionals on oral-systemic link?
• Dental care utilization
▫ Do people with chronic conditions get more dental
services?
• Collaboration
▫ Does the health care system support collaborative
care?
Knowledge
• 2 Studies, surveys among :
▫ Nephrologists & CKD nurses
▫ Internists and Endochronologists
• Results:
▫ Medical professionals often have a good
understanding of periodontal disease and its role
in systemic diseases
▫ They may not be confident or consistent in
performing oral health screenings or referrals
Knowledge, continued
▫ Reasons for not acting on knowledge are not clear
▫ Most agree that periodontal disease should be
included in medical training

Dental and Dental Hygiene Training
• The majority of surveyed dental and dental
hygiene schools include systemic disease
complications
• Most responding schools taught the oralsystemic link
• Very few (<4%) had multidisciplinary courses
• Less than 10% of respondents were confident
that medical personnel understood the oralsystemic link
Training to Action?
• Dental hygienists reported that they did not
routinely education DM patients on the oralsystemic link
▫ Lack of time
▫ Patient disinterest
▫ Inadequate information

of oral health information for patients with diabetes. J Public Health Dent. 2009 ; 69(2): 135–141.
doi:10.1111/j.1752-7325.2008.00111.x
Utilization
• CKD and DM: Fewer patients with these
conditions receive dental care than healthy
patients
• CKD
▫ 5 year study period: 15% of patients had a dental
visit
• DM
▫ 5 year study period: Fewer visits and procedures
▫ More likely to have perio tx or maintenance
DM
• Fewer procedures than healthy patients
• More periodontally related procedures
Collaborations: Barriers
• Perceived or actual barriers impact
collaborations
• Reasons for non-collaborative care among both
medical and dental professionals:
▫ Inadequate knowledge
▫ Feeling that nothing could be done to help
▫ Division between medical and dental care delivery
“Syndemic” Paradigm:
• Fragmented healthcare delivery system
• Management of chronic diseases must occur in a
new paradigm based on a “syndemic” approach
• Syndemic refers to two or more linked health
conditions that interact to increase the overall
disease burden
Iacopino A. New “syndemic” paradigm for interprofessional management of
chronic inflammatory disease. JCDA 2009; Vol. 75(9):632-33
Paradigm Shift?
• Treatment teams
▫ support comprehensive patient management
• Bidirectional screening and referral
• Collaborative reinforcement of educational
messages
• Communication and education among
professionals
▫ Professional training and CE
• Health policies that focus on risk reduction
Challenge
• Does your healthcare facility demonstrate:
▫ Adequate knowledge about systemic conditions
and treatments?
▫ Common CE?
▫ Collaborative practices?
▫ Treatment teams?
▫ Supportive policies?
• Develop an Action Plan!
