Study Notes
Comparison of AAP Classifications
- 1999 AAP classification included 8 major categories for periodontal diseases.
- 2018 AAP classification streamlined categories to 4 major classifications.
Determinants of Periodontal Phenotype
- Periodontal phenotype is influenced by several factors:
- Gingival thickness: Determines gum health and response to therapy.
- Keratinized tissue width: Affects stability and resilience of the gingiva.
- Bone morphotype: Thickness of the buccal plate impacts periodontal support.
Assessment of Periodontal Phenotype
- Assessment involves probing visible aspects of gingiva.
- A visible probing depth of 1mm suggests a thin phenotype.
Definition of Gingival Recession
- Gingival recession is the apical shift of the gingival margin.
- Can result from various conditions and is linked to clinical attachment loss (CAL).
- Applies to all surfaces of the teeth.
Classification of Gingival Recession
- RT1: Recession without loss of interproximal attachment.
- RT2: Recession with loss of interproximal attachment.
- RT3: Recession associated with loss of interproximal attachment.
Understanding Occlusal Trauma
- Occlusal trauma leads to lesions in the periodontal ligament, cementum, and surrounding bone.
- Caused by excessive or misaligned occlusal forces.
Traumatic Occlusal Forces
- Defined as any occlusal force that injures teeth or periodontal attachments.
Clinical Signs of Traumatic Occlusal Forces
- Common indicators include:
- Fremitus: Movement of teeth when occluded.
- Mobility: Increased looseness of teeth.
- Thermal sensitivity: Pain in response to temperature changes.
- Occlusal wear: Wear patterns on occlusal surfaces.
- Fractured teeth: Visible breaks in tooth structure.
- Radiographically widened PDL space: Indicates stress on periodontal ligaments.
- Root resorption: Loss of tooth root structure.
- Hypercementosis: Excessive cementum deposition on roots.
Non-Carious Cervical Lesions (NCCLs)
- NCCLs are areas of hard tissue loss at the cervical third of the crown and surrounding root surface.
- Occur through mechanisms unrelated to caries.
Factors Related to Dental Prostheses and Teeth
- Localized tooth-related factors: Modify conditions that lead to plaque-induced gingival disease or periodontitis.
- Localized dental prosthesis-related factors: Specific to the influence of dental appliances on periodontal health.
