Limitations of Nonsurgical Therapy

• Pocket Depth • 1-3mm 89% clean, 3-5mm 39% clean, >5mm 11% clean (Waerhaug 1978)

• 3.7 mm- Average PD that can be efficiently cleaned with Sc/RP

(6.2mm- average limit)

• Root Anatomy • CEPs, CEJ, Furcation, root flutes, line angles

• Access

• Long-term maintenance • Sc/RP teeth require retreatment twice as often compared to surgical

treatment (Ramfjord 1987)

• Patient compliance (OH, systemic health)

Is it realistic to perform ScRP in GD office? Does it benefit patient?

• Minimal osseous involvement?

• Biotype: thick vs thin

• Radiographic bone loss – infrabony defects

– Severity of bone loss; depth of pocket

• Understanding type of pockets vs Expected Response

– Soft tissue pocket

– Hard tissue pocket

– Combination

Pre-op and 1 year Post-op

Do you prefer that we do ScRP prior to referring?

• “Refer” - Goals of therapy

• Understanding type of pockets vs Expected Response

– Soft tissue pocket

– Hard tissue pocket

“How do we get a patient to see you if we can’t care for patient adequately?”

• Pt has to “own” their problem

• If patient does not see the urgency in getting their own disease treated, then no amount of effort will work

• Time, Trust, Consistency, Urgency, Confidence

What is the impact of occlusion on periodontal disease?

• Health

– Increase PD

– No Bone Loss

– Mobility

• Elimination of occlusal issue resolves periodontal issues

• Disease

– Increase PD

– Bone loss: Progressive

– Mobility

– Pathologic Migration

• Elimination of occlusal issue leave persistent periodontal issues

Occlusal Trauma and Periodontitis

Historically there has been two conflicting schools of thought:

Grinders Grind free

Pathologic force (excessive or off axis) results/contributes to alterations in the inflammatory front around teeth.

This in turn results in bone loss and attachment as collagenase and osteoclastic activity increases.

Occlusal Trauma and Periodontitis

• Intrabony defects associated with occlusal trauma assume many forms.

• The most commonly seen defect in “My Chair” seems to be the circumferential.

• What tooth is most commonly affected by occlusion??

WHAT DO WE CALL IT?

• Non-Carious Cervical Lesion

• Cervical Erosion

• Cervical Abrasion

• Abfraction

• Dental Compression

ALWAYS REMEMBER

Your initial diagnosis is a presumptive diagnosis

You must re-evaluate your diagnosis during treatment and after treatment to prevent missing the true diagnosis / etiology

What is the prognosis of your treatment? What length of treatment benefit do you expect?

How often should you perio chart an adult patient?

• Periodontal Disease pt

– Changes charted every periodontal maintenance visit

– Annual full mouth charting

• Healthy

– Annually full mouth charting

How young should you begin perio charting?

• Look at clinical parameters: radiographs and clinical presentation

• Deciduous and Mixed Dentition

– Aggressive Periodontal Disease: Early onset, localized juvenile periodontitis

• Adult

– Previously addressed

Peridontal Disease Classification

Discuss causes of inflamed tissue around implants

• Cement

• Plaque

• Tissue quality: lack of attached tissue

What’s wrong with this x-ray?

Earliest age for implant placement? Congenitally missing teeth

• Growth

– Boy : 20-21

– Girls: 18-20

• Mini-implants

• Conventional implants

Time period b/w implant placement and crown What if you had to wait a long time to restore

• Implant stability

• Type of bone

• Amount of bone

– Grafting needed

• Risks

– Still get bone remodeling as if nothing is there. Loading important in maintaining bone

– Super-eruption of opposing teeth

– Tilt of adjacent teeth over the implant

Can you place an immediate implant on a posterior tooth

Immediate implants; success rates

• Patient Selection very important

• Success vs Survival rates

• Stability - Key

• Restorability - Critical

• Equal success rates dependent on patient selection

• Increased ridge resorption after extraction

• Increased risk of tooth loss?

– 1% density loss -- 4x risk for tooth loss

• Increased risk for periodontal disease?

– Greater progressive loss of attachment

Bisphosphonates: options for implants and bone grafts

• Oral vs IV drugs

“Are you using a laser for tissue reduction?”

• Lasers available: Nd:Yag; Diode; CO2; Er:Yag; Argon

• Nd:Yag

– Readily absorbed in pigments (dark pathogens, blood)

– No readily absorbed by water and HA

– Standard protocol and training

– Research and Results

Clinical effects of Nd: Yag laser

• Removes the pocket epithelium

• Kills pathogens

• Neutralizes endotoxin

• Reduces inflammation and inflammatory products (PGE, IL, MMP, TNF)

• Biostimulation (increased growth factors and cell activity)

Why we use a Nd:Yag laser

• Hybrid between surgery and Sc/Rp

• Avoids Sc/Rp charge so increases treatment acceptance and decreases time for case completion

• Do not have to take patient off of anticoagulant therapy

• Less invasive for older patients and patients with poor systemic health

• Prevents significant recession unless you purposely create it

• No sutures to create tension or irritation

• No coronal creep of papilla over the mesial concavities of premolars

• Most likely prevents the 0.5 - 1mm of crestal resorption associated with flap reflection

• Patients love it and tell their friends! (Polar opposite of traditional surgery)

• Will we be able to use it as a future definitive therapy in patients on IV bisphosphonates?

Is it effective in PD reduction?

Oral Pathology The following are questions to think about when evaluating oral lesions:

1. Review medical history: smoking, diabetes, medications, radiation therapy, cancer history

2. Review dental history: look for causes of tissue trauma

3. Extraoral and Intraoral Exams (palpation of lymph nodes, lesions): size, soft, firm, fixed

4. Etiology: calculus, plaque, habits, appliances

5. Pain: If no pain and it looks like it should hurt, this can be a red flag.

6. Duration: new; present longer than 2 weeks

7. Frequency: new or recurring

8. Pattern: localized or generalized; unilateral

9. Location: attached gingiva, mucosal tissue, tongue, FOM, retromolar pad

10. Palpation: does surface wipe off, bleeding, soft, firm, fixed

11. Radiographic findings: crestal bone loss, -luscency, -opacity, calculus present

Take Home Message

1. Duration: If a lesion is present longer than 2 weeks — biopsy warranted! Do not wait until next cleaning to check lesion. Bring back in 2 weeks if necessary.

2. If you have no idea, ask your dentist to evaluate. May need to refer to a Periodontist or OMS

3. If you are not looking, you may not notice a lesion until it has progressed too far.

Why don’t perio offices employ Arestin Tx for non-sx pockets?

• Goal of Therapy

• Radiographic defect present?

• Residual calculus present?

• Clinical vs statistical significance?

• Long term results vs other treatment modalities

Efficacy of Antibiotic Therapy

• Depends on:

– Anti-microbial spectrum and drug characteristics

– Drug binding to tissues

– Protection of pathogens by non-target organisms

– Biofilm phenomena

– Total bacterial load vs. max antibiotic concentration

– Effectiveness of host defenses

– Pathogens in sites not affected by therapy

Do you think Arestin helps much in reducing PD’s?

• What do you find is the typical result / application?

• What is the frequency of application?

• What is the value of the therapy?

What criteria for Arestin use?

• Soft tissue refractory cases

– Inflammation

• Localized deepening pockets

Chemotherapeutics

• All local delivery antibiotics must be combined with Scaling and Root planing!

• Do not use them as a stand alone therapy

• Residual calculus is an issue. Even sterilized calculus acts as a chronic irritant

• Local antibiotics are beneficial in certain situations but should not be used in 50 sites at every maintenance appointment

If you were bleeding to death would you keep putting new band-aids/Neosporin on the wound every 2 minutes or would you go the hospital to fix the problem?

Chemotherapeutics Obstacles

• Residual calculus • Inflammation causes outflow of GCF at a rate of

44ul/min. The flow/pressure is out of the sulcus! • Deep intrabony defects have tissue bridging the defect.

This will not miraculously close. • Allergy • Costly • Over medicated culture • Patients are referred to us after several rounds of Sc/Rp

and Arestin and still need surgery…are enraged unless the dentist communicated adequately.

• Meta analysis only shows modest short term gains in attachment

Periostat use?

• No longer on the market

• Concept: Low Dose Doxycycline

• $$, 3 x 3 months

• Statistical vs Clinical significance

Low Dose Doxycycline

• PERIOSTAT® (doxycycline hyclate 20 mg capsules)

No longer available

• Periostat™ acts as an Enzyme Suppressor

– Studies show that doxycycline hyclate 20 mg bid has no antimicrobial action

– No change in bacterial flora after 18 months

– No induction of resistance after 18 months

Low Dose Doxycycline (LDD)

How long can a patient stay of Peridex?

• Concentration: full strength vs diluted

• Alternating days

• Stain effects

• Calculus formation

• Why is being used?
