Nonsurgical Periodontal Therapy and Adjunctive Therapy

Discusses components of initial periodontal therapy focusing on nonsurgical periodontal therapy (NSPT).
Highlights periodontal debridement as the "gold standard" in NSPT.
NSPT involves the removal of dental biofilm, endotoxins, bacterial products, and calculus.
Goals include the elimination of local factors contributing to periodontal disease and the use of adjunctive agents.
Emphasizes the importance of re-evaluation post-therapy.

Goals of Nonsurgical Periodontal Therapy:
- Explain goals and clinical outcomes.
- Devise a care plan for slight-to-moderate chronic periodontitis.
- Describe subgingival bacteria changes post-debridement.
- Discuss evidence of laser therapy for initial treatment.
- Develop postoperative instructions following NSPT.
Evaluation and Comparison:
- List re-evaluation steps and clinical decision-making based on outcomes.
- Compare systemic antibiotics and local delivery antimicrobials, including risks and benefits.
- Critically assess the impact of local delivery antimicrobials on pocket depth and clinical attachment level (CAL).

Definition:
- NSPT is focused on removing dental biofilm and contributing factors to periodontal disease without surgery.
Components:
- Initial periodontal therapy, primarily through periodontal debridement.
- Addressing local factors in periodontal disease.
- Integration of adjunctive agents to support therapy.
- Importance of re-evaluation to assess treatment effectiveness.

Goals:
- Interrupt or arrest disease progression.
- Create a healing environment and resolve inflammation.
- Induce positive changes in subgingival biofilm quality and quantity.
- Educate and motivate patients for effective biofilm management.
- Prepare tissues for potential surgical interventions in advanced cases.
Table 39-1: Effect of Subgingival Instrumentation on Pocket Microflora:
- Periodontal Infection before Treatment:
- Predominant flora: Anaerobic, Gram-negative, motile, including spirochetes.
- Total microbial count: Very high with numerous microorganisms.
- Leukocyte count: Elevated.
- Periodontal Health after Treatment:
- Predominant flora: Aerobic, Gram-positive, non-motile (coccoid forms).
- Total microbial count: Much lower overall counts.
- Leukocyte count: Decreased.

Gingivitis:
- Define therapeutic goals and treatment approaches.
Stage I to III Periodontitis:
- Specific therapeutic goals and corresponding treatment protocols.
Moderate-to-Severe Periodontitis:
- Address therapeutic needs for patients with significant disease, especially those who have unresponsive cases.

Appointment Planning:
- Options include single or multiple appointments, depending on the case.
- Consideration of full-mouth disinfection strategies and definitive NSPT procedures.

Pre-treatment Assessment:
- Review patient's assessment records, radiographs, care plan, and treatment records before proceeding.
Examinations Required:
- Supragingival examination and subgingival examination.
- Use of tools like a probe for access and conditions (Figures 39-1 and 39-2 show anatomical variations).

Definitions:
- Importance of understanding subgingival anatomy during debridement.
Instrumentation Techniques:
- Detailed steps for calculus removal using manual instruments (found in Box 39-1).
- Channel scaling outlined (see Figure 39-5).

Utilization of various instruments including:
- Furcation debridement tools.
- Advanced ultrasonic/piezoelectric tips.
- Subgingival air polishing (illustrated in Figure 39-6).
- Laser therapy for enhanced outcomes.

Focus on managing patient discomfort and enhancing oral self-care methods:
- Importance of rinsing and dietary recommendations.
- Biofilm management strategies and emergency protocols.
- Format for providing patient instructions clearly outlined.

Clinical Endpoints:
- Recommended re-evaluation time frame is 4-8 weeks post initial therapy.
- Procedure includes a comprehensive periodontal examination and establishing ongoing care intervals for the patient.

Antimicrobial Therapy:
- Overview of systemic delivery of antibiotics and considerations regarding their action, selection, and limitations.
- Systemic subantimicrobial dose antibiotics overview.
- Local delivery antimicrobials: advantages and limitations discussed.

Situations warranting local delivery include:
- Nonsurgical periodontal therapy context.
- Adjunctive treatments at re-evaluation.
- Management of recurrent disease or peri-implantitis.
- Evidence of efficacy for local delivery antimicrobial agents is noted as weak in some cases.

Examples and Illustrations:
- Minocycline hydrochloride (Figure 39-7).
- Doxycycline hyclate (Figure 39-8).
- Chlorhexidine gluconate (illustrated in Figure 39-8).

Documentation Requirements:
- Detailed medical history, assessment examination findings, and vital signs recording.
- Oral examination status after treatment, noting healing progress.
Biofilm Index and Additional Instructions:
- Noting treatment completed, bleeding instances, and specific areas requiring further evaluation at the next visit (see Box 39-2 for a progress note template).

Key Concepts for Patient Education:
- The significance of dental biofilm in periodontal pathogens and calculus occurrence.
- Patient responsibility for thorough daily biofilm removal.
- Rationale for multiple appointments and the necessity of re-evaluation post-treatment.
- Importance of patient involvement in maintaining therapeutic results and the considerations for potential referral to a periodontist if nonsurgical treatments fail.

Comprehensive understanding of nonsurgical periodontal therapy methodologies and adjunctive therapies is crucial for effective patient management and treatment outcomes in periodontal health. This includes patient education, rigorous documentation, and post-therapy evaluation, leading to enhanced clinical results.
