This treatment planning guide was originally created in 1989 by Dr. Ron Van Swol to help standardize

periodontal treatment at Marquette University School of Dentistry. With the changes that have

occurred in periodontics since that time, an update has become necessary. This document has been put

together to provide non-periodontal faculty and all students of Marquette University School of

Dentistry with an overview of the philosophy of periodontal treatment at Marquette. It is not meant to

cover every possible clinical situation or replace sound clinical judgment that may require alternative

approaches for unique cases.

CASE TYPE I

Clinical Features:

- More generalized gingivitis

- Most sulcus depths are 1-3 mm with the possibility of an occasional 4 mm pseudopocket

- Some bleeding upon probing

- Normal mobility—less than 0.5 mm

- No furcation involvements

- No active bone loss

- No active loss of periodontal attachment

PERIODONTAL MANAGEMENT

I. Periodontal examination, charting; formulation of a diagnosis, prognosis, and treatment plan

II. Periodontal treatment

A. Systemic Phase (PRN)

B. Acute Phase (PRN)

C. Disease Control Phase

1. Oral Hygiene Instruction

2. Prophylaxis (Code D1110; AKA Scale & polish)

3. Re-evaluation in 2 weeks for oral hygiene monitoring and pocket reduction. If appropriate, case

completion. If disease is not eliminated, continue treatment; i.e., repeat A, B, and C.

D. Definitive (Periodontal Surgical Therapy)

1. Usually none

2. Elective surgery, if indicated: Free Gingival Graft, Frenectomy, crown lengthening, distal

gingivoplasty, etc.

E. Maintenance

1. Preventive Maintenance (D1110)

2. Generally every 6 months, depending on patient’s plaque control, and overall risk profile

CASE TYPE II (almost always Chronic / on rare occasions Aggressive)

Page 5: Periodontal Diagnosis Case Classification and Potential Treatment Guide

4

Clinical Features:

- Gingivitis with early periodontitis

- Periodontitis may be localized (< 30% of sites) or generalized ( > 30% of sites)

- Moderate pocket depths (4-5 occ. 6 mm pockets)

- Early/slight attachment loss (1 – 3 mm from CEJ to base of pocket)

- Moderate bleeding upon probing, and more generalized than Type I

- Early to very moderate bone loss (10-20%), usually localized and primarily of the horizontal type.Radiographically, one would see loss of crestal radio-density characterized on the X-ray by localized fuzzy orbroken crestal lamina dura.

- Most mobilities normal, but is possible to record some Class I’s.

- No furcation involvement or an isolated Grade I

- Gingiva may present rolled margins with enlarged papillae, this being either localized or generalized.

ii. Trial maintenance

iii. Compromised maintenance

2. Every 3, 4, or 6 months depending on patients plaque control and overall risk profile

COMMENT: True early generalized or localized chronic periodontitis can often be managed successfully without surgery,

particularly on single rooted teeth. However, particular attention must be given to the patient’s response to treatment to

ensure that appropriate endpoints of therapy have been reached. The following questions can help guide the decision.

Is bleeding on probing reduced? (goal 0 –15%)

Have probing depths decreased to maintainable levels? (goal 1 – 4 mm)

Have clinical attachment levels improved?

CASE TYPE III (chronic or aggressive)

- Pocket depths are generally 4-6+ mm

- Moderate clinical attachment loss (4 – 5 mm from CEJ to base of pocket)

- Moderate bone loss (20-40%); this primarily horizontal in nature particularly for chronic cases. There is thepossibility of localized vertical bone loss.

- Generalized bleeding upon probing

Adjunctive Periodontal Therapies and General Comments

Topical Antiseptic Rinses

Chlorhexidine Gluconate 0.12% - Most useful as a BID mouth rinse during disease

control phase to help eliminate or reduce pathogenic flora and during the immediate

post-surgical phase to prevent reinfection. Not recommended for long term use.

Listerine Antiseptic – Most useful as a BID mouth rinse during maintenance phase to

reduce plaque and gingivitis. LA may also have some benefit as a sub-gingival irrigant

in the highly motiviated periodontitis patient during maintenance phase as a part of

home care and as an in-office subgingival irrigant for patients who require SBE

prophylaxis

Systemic Antibiotics – Not generally recommended in chronic periodontitis cases with

the possible exception of the poorly controlled diabetic patient. Use of the systemic

antibiotic should be considered the standard of care in forms of aggressive or refractory

cases.

Locally placed, Controlled Release Antimicrobials

Contraindicated in aggressive or refractory periodontitis cases.

Most useful for isolated recurrent sites in the chronic periodontitis patient during

maintenance phase. Can be considered a viable treatment for isolated sites in patients

who are poor surgical candidates. Placement of these agents must be preceded by

Page 13: Periodontal Diagnosis Case Classification and Potential Treatment Guide

thorough scaling and root planing. Arestin, Atridox and PerioChip are currently used in

the MUSoD Clinic.

Host modulating agents

Periostat – 20 mg doxycycline BID for 90 days. Enzyme inhibitor with

limited/unremarkable antibacterial properties. May be useful in recurrent or refractory

periodontitis cases. Long term cost-benefit analysis of this therapy is not clear and

should be used sparingly. Cost for a 3 month regimen is ~$540.

Surgical vs. Non surgical therapy

In general, even single rooted teeth with probing depths of > 6 mm require surgical

access for proper debridement. This is particularly true in a dental school setting where

the non-surgical therapy is provided by a novice.

Multi-rooted teeth or teeth with significant root grooves or concavities often require

surgical access even in moderate probing depths (4-6 mm).

In the untreated periodontitis patient, prophylaxis should not be carried out prior to

scaling and root planing. In the treated perio patient all maintenance is D4910.

Mobile teeth should be stabilized prior to surgery for an adequate result.

Good plaque control is an important criterion for surgical treatment.

Implant therapy

Implants are a viable option for many patients and can be placed by periodontists as

well as oral surgeons. Careful treatment planning is a must in these cases.

Maintenance therapy criteria for assessing stability

Site and Patient-level criteria that students and faculty should consider in assessing the

stability of periodontal patients at the MUSoD clinics should include the following:

a. Inflammation as measured by bleeding on probing (BOP) i. Full mouth BOP > 15%, suggests instability ii. Sites that consistently show BOP overtime may be unstable iii. Sites that consistently show no BOP are likely stable

b. Probing depth measurements (PD) i. Sites with PD increase of > 2 mm from baseline or previous visit, unstable ii. # of significant periodontal pocket depths (10 or more sites > 4mm PD, unstable) iii. 6 mm or greater PD at any site consider unstable iv. Progressive gingival recession from baseline or previous charting

c. Radiographic considerations i. Loss of crestal bone height based on vertical bite wings, unstable ii. Consistent presence of crestal lamina dura suggests stability

d. Patient-level considerations i. Poor hygiene in the presence of attachment loss PI > 30%, unstable ii. Smoking > _ Pack /day, unstable iii. Diabetic with HBA1c > 9, unstable iv. High stress events, divorce, loss of loved one, unemployment, unstable
