Course Overview

Non-surgical periodontal therapy remains a fundamental component of periodontal care.

However, effective treatment requires more than simply performing routine scaling.

The clinician must determine:

• Where subgingival deposits remain
• Whether adequate debridement has been achieved
• Which pockets require reevaluation
• Whether tissues are responding to therapy
• Whether further non-surgical treatment is reasonable
• Whether adjunctive therapy may be considered
• When surgical management becomes appropriate
• How long-term stability should be maintained

This course organizes those decisions into a practical clinical framework.

Non-Surgical Periodontal Therapy

A comprehensive non-surgical approach may incorporate:

• Patient education
• Biofilm control
• Supra- and subgingival instrumentation
• Scaling
• Root surface debridement
• Reevaluation
• Maintenance

The objective is not simply to remove visible deposits but to establish clinically meaningful periodontal endpoints.

Scaling and Root Planing

Scaling and root planing remain key concepts within non-surgical periodontal treatment.

The course focuses particularly on:

• Manual instrumentation
• Modified subgingival techniques
• Residual calculus
• Clinical execution
• Follow-up

The emphasis is on adapting instrumentation to the clinical site rather than applying the same sequence mechanically to every patient.

LESSON 1

Non-Surgical Periodontal Tissue Management: Biological Principles, Instrumentation Protocols, and Clinical Endpoints

Instructor: Marisa Roncati
Duration: 22 Minutes
Official OHI-S CE: 0.25 Credit

Lesson 1 establishes the biological and clinical framework for non-surgical periodontal therapy.

Topics include:

• Biological principles of periodontal healing
• Bone remineralization concepts
• Longitudinal periodontal cases
• Periodontal stability
• Calculus detection
• Subgingival debridement
• Residual calculus removal
• Root debridement
• Clinical treatment endpoints

Biological Response After Therapy

Periodontal tissues can demonstrate substantial clinical improvement after effective non-surgical treatment.

However, treatment response varies between:

• Patients
• Teeth
• Sites
• Defect morphologies

The course therefore avoids treating periodontal healing as completely predictable.

Bone Remineralization

OHI-S specifically discusses the biological rationale behind unpredictable yet achievable bone remineralization following non-surgical therapy.

This is an important distinction.

The course demonstrates longitudinal cases and discusses how changes can be evaluated over time, but bone regeneration or remineralization should not be represented as guaranteed following scaling and root planing.

Calculus Detection

Residual subgingival calculus can compromise periodontal treatment.

The curriculum therefore includes protocols for:

• Detecting residual calculus
• Identifying incompletely debrided areas
• Re-instrumenting when appropriate

A useful clinical sequence is:

Detect → Instrument → Reassess → Verify Endpoint

Root Debridement

Effective root debridement requires more than aggressive instrumentation.

The goal is controlled removal of deposits and disruption of pathogenic biofilm while preserving tissues as appropriately as possible.

Clinical Endpoints

One of the strongest topics in Lesson 1 is identifying meaningful clinical endpoints after instrumentation.

The clinician must decide:

When Has Adequate Debridement Been Achieved?

This requires clinical judgment rather than simply counting instrument strokes.

LESSON 2

Manual Scaling Techniques and Clinical Outcome Analysis

Instructor: Marisa Roncati
Duration: 18 Minutes
Official OHI-S CE: 0.25 Credit

Lesson 2 moves into practical instrumentation.

Topics include:

• Periodontal follow-up protocols
• Manual scaling demonstration
• Modified manual subgingival instrumentation
• Clinical rationale for instrumentation
• Scaling and root planing protocols
• Management of periodontally compromised patients
• Bone remineralization assessment
• Post-treatment clinical cases
• Literature review

Modified Manual Instrumentation

The course demonstrates a modified approach to manual subgingival instrumentation.

The objective is to improve:

• Access
• Calculus removal
• Root-surface debridement
• Procedural control

while adapting technique to the anatomy of the periodontal pocket.

Manual Scaling

Manual instrumentation remains highly relevant even in practices using ultrasonic technology.

Clinical competence requires understanding:

• Instrument adaptation
• Working angulation
• Pressure
• Stroke control
• Root anatomy
• Furcations
• Pocket morphology

Follow-Up Protocols

Periodontal treatment does not end after the initial debridement appointment.

Follow-up helps determine:

• Reduction in inflammation
• Changes in probing depths
• Residual bleeding
• Persistent calculus
• Patient plaque control
• Need for additional treatment

Clinical Outcome Analysis

Longitudinal cases allow the practitioner to compare:

Baseline → Non-Surgical Treatment → Reevaluation → Maintenance

This helps distinguish true treatment response from assumptions based only on immediate post-treatment appearance.

LESSON 3

Laser-Assisted Non-Surgical Protocols in Advanced Periodontal Therapy

Instructor: Marisa Roncati
Duration: 19 Minutes
Official OHI-S CE: 0.25 Credit

This lesson examines the adjunctive use of laser therapy in advanced periodontal treatment.

Topics include:

• Generalized Stage III–IV periodontitis
• Grade B–C disease
• Indications for laser-assisted treatment
• Limitations of laser therapy
• Diode laser application
• Advanced non-surgical protocols
• Periodontal reevaluation
• Initial probing depths ≥6 mm
• Surgical vs. non-surgical decision-making
• Peri-implant disease protocols

Laser Therapy as an Adjunct

The most important wording for this module is:

Adjunctive

The laser should not be presented as replacing:

• Diagnosis
• Mechanical debridement
• Biofilm control
• Periodontal maintenance
• Surgical treatment when indicated

The official curriculum specifically discusses both the indications and limitations of laser-assisted therapy.

Diode Laser in Periodontal Therapy

The program reviews integration of a diode laser into selected non-surgical periodontal protocols.

The clinician should understand:

• Treatment indication
• Device-specific training
• Tissue response
• Safety
• Limitations

rather than simply adding laser treatment to every periodontal pocket.

Stage III–IV Periodontitis

Lesson 3 specifically addresses advanced disease classified as:

• Stage III
• Stage IV
• Grade B
• Grade C

This adds a strong evidence-based periodontology keyword cluster to the product.

Reevaluation of Deep Periodontal Pockets

The official course specifically asks how and when to reevaluate sites that initially demonstrate:

Probing Depth ≥6 mm

Reevaluation can help determine whether the patient requires:

• Continued non-surgical management
• Additional debridement
• Adjunctive treatment
• Surgical consultation or intervention

Periodontal vs. Surgical Treatment

A central theme is recognizing the limits of non-surgical therapy.

The objective is not to avoid surgery at all costs.

Instead:

Use Non-Surgical Therapy Where Appropriate → Measure Response → Escalate When Clinically Indicated

Peri-Implant Disease

Lesson 3 also extends non-surgical thinking to peri-implant diseases.

OHI-S specifically includes a laser-assisted peri-implant protocol and the associated clinical decision-making process.

This makes the course relevant not only to periodontists but also to implant clinicians involved in maintenance and complication management.

PERIODONTITIS vs. PERI-IMPLANT DISEASE

These conditions share inflammatory features but should not be treated as identical diseases.

Important differences exist in:

• Tissue anatomy
• Implant surface
• Instrument selection
• Debridement access
• Treatment response

The clinician should adapt treatment accordingly.

LESSON 4

Clinical Strategy for Achieving Long-Term Periodontal Stability

Instructor: Marisa Roncati
Duration: 37 Minutes
Official OHI-S CE: 0.5 Credit

The final lesson focuses on long-term clinical decision-making.

Topics include:

• Patient-related risk factors
• Surgical vs. non-surgical treatment
• Nonresponsive sites
• Indications for periodontal surgery
• Severely compromised teeth
• Compromised implants
• Cases in which surgery is contraindicated
• Evidence review
• Patient expectations
• Long-term outcomes
• Periodontal stability

Long-Term Periodontal Stability

The goal of periodontal therapy is not merely a short-term reduction in inflammation.

Long-term stability requires:

• Patient plaque control
• Periodontal maintenance
• Reassessment
• Risk-factor management
• Early detection of recurrent disease

When Non-Surgical Therapy Is Not Enough

The curriculum explicitly addresses indications for surgical management after a site has failed to respond adequately to non-surgical therapy.

This is clinically important because repeated instrumentation without a clear endpoint may not resolve every periodontal defect.

Surgical vs. Non-Surgical Decision-Making

A useful framework is:

Initial Therapy

↓

Reevaluation

↓

Residual Pocket / Inflammation?

↓

Assess Anatomy + Risk + Patient Factors

↓

Additional Non-Surgical Therapy OR Surgical Management

Severely Compromised Teeth

The course also discusses management when teeth remain severely compromised.

Treatment planning may need to consider:

• Prognosis
• Periodontal support
• Patient preference
• Surgical feasibility
• Maintenance potential

Compromised Implants

The same principle applies around implants.

The clinician should determine:

• Disease severity
• Implant stability
• Bone loss
• Soft-tissue condition
• Prosthetic access
• Maintenance potential

before selecting continued non-surgical management or escalation.

When Surgery Is Contraindicated

One of the more practical elements of Lesson 4 is management of patients in whom surgery may not be feasible or appropriate.

This reinforces the importance of optimizing:

• Non-surgical care
• Maintenance
• Risk management
• Patient-specific treatment objectives

Supportive Periodontal Therapy

Successful active therapy should transition into long-term supportive care.

Maintenance appointments may incorporate:

• Periodontal probing
• Bleeding assessment
• Plaque evaluation
• Professional debridement
• Oral-hygiene reinforcement
• Implant assessment
• Risk reassessment

Periodontal Maintenance

Periodontal disease should be managed as a chronic condition requiring ongoing surveillance.

A useful long-term pathway is:

Active Therapy → Reevaluation → Stabilization → Supportive Periodontal Care → Reassessment

Evidence-Based Decision-Making

The official curriculum includes critical review of literature within several lessons.

The objective is to connect:

Clinical Experience

with:

Current Evidence

rather than relying only on anecdotal protocols.

Why This Course Is Useful

The course combines four essential stages of non-surgical periodontal care:

1. Instrumentation

• Scaling
• Root planing
• Residual calculus removal

2. Reevaluation

• Probing depths
• Clinical endpoints
• Healing response

3. Adjunctive Therapy

• Diode laser
• Advanced periodontal cases
• Peri-implant disease

4. Long-Term Strategy

• Maintenance
• Surgical indications
• Compromised teeth and implants
• Stability

The complete clinical framework is:

Instrument → Reevaluate → Decide → Maintain

Important Laser Therapy Notice

The course discusses diode laser therapy as an adjunctive strategy.

It should not be marketed as:

• Replacing mechanical periodontal debridement
• Eliminating the need for surgery in all advanced cases
• Guaranteeing periodontal regeneration
• Guaranteeing bone remineralization

Device-specific laser use requires appropriate training and adherence to applicable safety and regulatory requirements.

Bone Remineralization Notice

OHI-S specifically describes bone remineralization as:

Unpredictable yet achievable

within selected longitudinal clinical cases.

Therefore, MedicalAmboss copy should avoid statements such as:

“This protocol regenerates periodontal bone.”

The more accurate wording is:

“The course reviews longitudinal post-treatment cases and protocols for evaluating bone remineralization following non-surgical periodontal therapy.”
