21 Clinical Decision-Making for Periodontal Care

Clinical Decision-Making for Periodontal Care

Foundations of Clinical Decision-Making

  • Clinical Decision-Making
    • A process whereby the dental team uses information from a comprehensive periodontal assessment to arrive at an appropriate diagnosis and identify treatment strategies.
    • It is the first step of treatment planning, which involves assigning the correct diagnosis.

Guidelines for Arriving at a Periodontal Diagnosis

  • Involves answering fundamental diagnostic questions:
    • Does the clinical assessment indicate periodontal health or inflammatory disease?
    • If the clinical assessment indicates inflammatory disease, is the disease gingivitis or periodontitis?
    • If the patient has gingivitis, what type is it?
    • If the patient has periodontitis, what type is it?

Identifying Periodontal Health or Inflammatory Disease

  • Signs of Disease

    • Defined as directly observable or measurable features of disease.
    • Common signs of periodontal disease include:
    • Gingival erythema (redness)
    • Gingival edema (swelling)
    • Bleeding on gentle probing
    • Loss of attachment
    • Tooth mobility
    • Loss of alveolar bone support
  • Symptoms of Disease

    • Features of disease noticeable only to the patient.
    • Example symptoms of Stage IV periodontitis include:
    • Loose teeth
    • Difficulty chewing
    • Profuse gingival bleeding
    • Bad taste in mouth
  • Periodontitis is often referred to as a silent disease due to early symptoms being subtle and going undetected.

    • Disease can progress to an advanced state causing serious complications.
    • Patients may remain unaware of the disease until overt symptoms appear.

Signs of Inflammation in the Periodontium

  • Table: Signs of Inflammation
    • Overt Signs (Readily Visible):
    • Color changes in gingiva
    • Contour changes in gingiva
    • Consistency changes in gingiva
    • Hidden Signs:
    • Bone loss (specific to periodontitis)
    • Purulence (exudate)
    • Bleeding on probing

Diagnostic Considerations

  • Periodontal Health

    • If the assessment shows absence of overt or hidden signs of inflammation, the diagnosis is periodontal health, indicating that inflammatory disease is not present.
    • Other issues may be present, but patient does not have gingivitis or periodontitis.
  • Inflammatory Disease

    • If signs of inflammation are present, the answer is inflammatory disease.
    • Indicates that some form of inflammatory disease is present and further diagnostic decisions must be made.
  • Additional diagnostic measures may be necessary even in the absence of inflammatory disease; for instance, if a patient shows severe gingival recession and cervical abrasions despite no inflammation, evaluation for traumatic tooth brushing history may be warranted.

Differentiating Between Gingivitis and Periodontitis

  • Diagnosis is based on clinical evidence of attachment loss.
    • Normal level of gingival attachment is slightly coronal to the level of the cemento-enamel junction (CEJ).
    • Clinical Attachment Loss (CAL) refers to the migration of the junctional epithelium to a position apical to the CEJ level.

Gingivitis vs. Periodontitis

  • Gingivitis

    • Defined as the presence of inflammation without attachment loss.
  • Periodontitis

    • Defined as inflammation with attachment loss present.
  • Importance of Radiographs

    • Dental radiographs and clinical findings should be used during the clinical assessment.
    • In most cases of periodontitis, alveolar bone loss is evident on radiographs prior to clinical attachment loss being detectable by a clinician.

Types of Gingivitis and Periodontitis

  • Dentists will use existing disease classifications to assign a periodontal diagnosis based on clinical features.
  • Changes in 2017 classification system include:
    • Peri-implant health
    • Peri-implant mucositis
    • Peri-implantitis
  • Document any other periodontal conditions identified during the diagnosis.

Recognizing the Need for Flexibility

  • Clinicians must maintain flexibility when assigning diagnoses due to the potential for multiple conditions to be present:
    • It is important to recognize that determining the presence of gingivitis or periodontitis may not encapsulate the overall condition of the patient.
    • Documentation should reflect all other periodontal conditions identified.

Examples of Other Findings

  • Findings that may be documented include:
    • Recession of gingival margin
    • Occlusal trauma
    • Aberrant frenum position

Documenting Periodontal and Peri-Implant Diagnosis

  • Documenting the periodontal diagnosis is critical and should adhere to a standard format.
  • Utilize the correct diagnostic terms per the classification scheme, such as gingivitis or periodontitis.

Disease Staging

  • Classify disease using a multidimensional staging system.
    • Staging of Periodontitis defines severity, complexity of management, and the extent and distribution of disease.
    • For peri-implant diagnosis, determine if the diagnosis is peri-implant health, peri-implant mucositis, or peri-implantitis.

Documentation of Disease Stage, Grade, and Extent

  • Modifiers in Disease Documentation
    • Table: Use of Modifiers
    • Disease Stage:
    • Stage I: Initial periodontitis
    • Stage II: Moderate periodontitis
    • Stage III: Severe periodontitis with potential for tooth loss
    • Stage IV: Advanced periodontitis with extensive tooth loss
    • Disease Grade:
    • Grade A: Slow rate of progression
    • Grade B: Moderate rate of progression
    • Grade C: Rapid rate of progression
    • Disease Extent:
    • Localized (30% or less of teeth involved)
    • Generalized (more than 30% of teeth involved)
    • Molar/incisor pattern (breakdown limited to molars and incisors)

Disease Grading

  • Grading classification is an indicator of the anticipated rate of periodontitis progression:
    • Grade A: Slow rate
    • Grade B: Moderate rate
    • Grade C: Rapid rate
  • Grading systems rely on direct/indirect evidence of progression and apply solely to periodontitis classification, not other conditions.

Treatment Planning Phases

  • The comprehensive periodontal master treatment plan serves as an outline of actions for the dentist, dental hygienist, and patient aimed at restoring a healthy periodontal environment.
  • Treatment plan phases include:
    • Assessment and Preliminary Therapy
    • Nonsurgical Periodontal Therapy
    • Surgical Therapy
    • Restorative Therapy
    • Periodontal Maintenance

Phases Explained:

  • Assessment and Preliminary Therapy Phase:

    • Involves evaluating collected data and urgent care for any acute conditions, sometimes classified as emergency therapy.
  • Nonsurgical Periodontal Therapy Phase:

    • Comprises measures used to control gingivitis or periodontitis, including intensive instrumentation and patient education.
  • Surgical Therapy Phase:

    • Encompasses any surgical interventions required to eliminate periodontal disease not manageable via nonsurgical means, including dental implant placement for missing teeth.
  • Restorative Therapy Phase:

    • Involves placing dental restorations and potentially replacing missing teeth with fixed or removable prosthetics.
  • Periodontal Maintenance Phase:

    • Entails ongoing measures by both dental teams and patients aimed at preventing the recurrence of periodontitis once controlled.
    • The target is ensuring teeth remain functional throughout the patient's life.

Importance of Ongoing Decision-Making

  • The goal of periodontal therapy is to preserve the periodontium, optimize oral health, and contribute to the overall well-being of the individual.
  • The periodontium consists of dynamic tissues that can undergo physiological remodeling or pathological destruction.
  • A patient's care plan often requires adjustments over time, necessitating consistent communication regarding their diagnosis and treatment plan.
