Study Notes
Chemotherapeutic Adjuncts in Periodontal Disease
- Chemotherapeutic adjuncts are chemical therapies used alongside, not instead of, the primary treatment.
- Their purpose is supporting periodontal treatment, not replacing it.
- Adjunctive therapies work by various mechanisms, including antimicrobial effects and host modulation.
Aims of the Module
- Understand what a chemotherapeutic adjunct is in periodontal disease treatment.
- Identify the appropriate adjunct based on delivery method (systemic or local).
- Determine if an adjunct is suitable and how to use it.
Intended Learning Outcomes
- Define the term "chemotherapeutic adjunct."
- Understand available adjunct delivery systems (local and systemic).
- Learn when to use chemotherapeutic adjuncts in periodontal disease.
- Review the evidence supporting the use of adjunctive therapies for periodontal disease.
- The learning outcomes are linked to specific GDC (General Dental Council) learning objectives.
Related Topics
- Students should draw on existing knowledge of the following topics:
- Plaque biofilm
- Mouthwashes (and their modes of action)
- Toothpastes (and their modes of action)
- Periodontal disease
What is a Chemotherapeutic Adjunct?
- A chemotherapeutic adjunct is a chemical treatment used as a supplementary aid to the main periodontal therapy.
- They are used to support, not replace, the core treatment.
- The adjuncts aim to provide antimicrobial effects (killing bacteria) and host modulation (improving tissue healing).
Why Use Adjuncts?
- Adjunctive treatments provide extra support.
- They buy time before a host response can take hold.
- They support active treatment by improving and reducing biofilm growth.
- Useful for localized unresponsive sites where mechanical debridement is limited.
- Reduce gram-negative bacteria post-operatively.
- Generally useful when combined with other surgical or mechanical interventions.
Adjuncts Cannot
- Substitute for adequate plaque control.
- Break down biofilm on their own.
- Be used long-term as a constant treatment.
- Control periodontal disease by themselves.
Adjunct Systems Available
- Systemic delivery (administered orally)
- Local delivery (applied directly to the affected area e.g. mouthwashes, gels, irrigations)
Systemic Delivery
- The agent is absorbed into the bloodstream, then distributed throughout the body, including the oral cavity and periodontal pockets.
- Some drugs are more concentrated in periodontal areas.
- This approach allows treatment to affect the whole body.
Types of Systemic Adjuncts
- Many antibiotic classes,
- e.g. Metronidazole, Amoxicillin, Tetracyclines (Minocycline, Doxycycline), Azithromycin
Systemic Delivery Advantages
- Easy administration.
- Drug levels are comparable to serum levels (except some tetracyclines) in the crucial crevicular fluid tissue.
- May access a wider distribution of micro-organisms.
Systemic Delivery Disadvantages
- Wide distribution throughout the body can cause side effects and lead to the development of resistant microorganisms.
- Difficult to target affected sites directly.
- Requires patient effort for long term adherence to treatment plans.
Local Delivery Systems
- These systems directly apply the agent to a localized area.
- Mouthwashes, gels, toothpastes, and floss are examples.
- They can only be used for supra-gingival plaque control.
Local Delivery System Types
- Examples include:
- Gingival gels (e.g., TePe, Gengigel, containing fluoride or other antimicrobials).
- Solutions applied for irrigation of gingival pockets
- Controlled-delivery agents that release medication over a prolonged time (e.g., periochip).
- Placement of preparations into the pockets.
Local Delivery Advantages
- Concentrated effects in treatment areas.
- Reduced systemic side effects (compared to systemic administration).
- May maintain the plaque control in affected areas.
Local Delivery Disadvantages
- Requires professional application in most cases
- Can be time-consuming to place.
- Patient compliance can influence treatment efficacy.
Use of Chemotherapeutic Adjuncts
- Plaque control and calculus removal are pre-requisites.
- The patient must exhibit good (adequate) plaque control habits.
- Mechanical disruption of biofilm is essential.
- Consider factors like patient adherence, cost, convenience and specific needs.
First Step Therapy
- Focuses on patient behavior modification for plaque biofilm and risk factor control.
- Emphasizes consistent plaque biofilm and risk factor control.
- Methods include: supragingival cleaning; oral hygiene training; professional or mechanical methods of plaque removal; patient education on health behavior change.
Second Step Therapy
- Targets subgingival deposits (biofilm and calculus).
- Subgingival instrumentation is a crucial initial step.
- Also consider adjunctive (additional, supporting) chemical agents; host-modifying agents; subgingivally administered antimicrobial agents; and systemic antimicrobials.
- Only initiate this step when a patient is engaged in the process; when the first phase is successful; and when subgingival deposits exist.
Third Step Therapy
- Targets non-responsive sites with deep pockets.
- Aims at addressing persistent problems.
- Treatment options may include further debridement, access flap surgery, periodontal surgery (resection or regeneration) and/ or specific types of localized advanced treatment procedures.
Supportive Periodontal Care
- Aims to support and maintain treatment, improving periodontal stability.
- Tailoring therapy timing to individual needs ensures long term effectiveness
- Recurrence of disease requires re-evaluation, diagnosis and further treatment if needed.
Evidence-based recommendations on adjunct use
- Review of current evidence supports the approach to using particular types of adjunct therapies based on factors like severity of gingival conditions; sites affected; and other patient-specific considerations.
Additional Points Regarding Systemic Antibiotic use.
- Systemic antibiotics are not a first-line treatment; are not routinely administered; and should be considered only for specific patient populations.
- The use of antibiotics should only be implemented when indicated by a specialist based on the unique aspects of each case and individual risk factor identification.
Summary of Conclusions
- Mechanical (non-surgical) treatment often resolves the situation without additional pharmacological treatments.
- Plaque control by the patient plays a critical role in the success of periodontal treatment.
- Adjunctive agents (local and systemic) can sometimes, in specific situations, improve the effectiveness of periodontal treatment.
