Study Notes
Dental Lesions and Periodontal Disease Summary
- Endo-perio lesions can occur when endodontic and periodontal issues combine in a tooth.
- These lesions can manifest as lesions starting apically in molars or on the cervical part of the tooth, sometimes merging depending on severity.
- Identification and diagnosis of endo-perio lesions are critical for effective treatment.
- Endo-perio lesions may present with deep pockets and distinct separation between endodontic and periodontal defects.
- Treatment of endodontic issues should precede periodontal treatment in endo-perio lesions to avoid negative outcomes.
- Communication between the periodontal and endodontic parts of the tooth can occur through apical foramen, lateral canals, dental tubules, and accessory canals.
- Exposed tubules in the root and accessory canals in the mid-third of the root can contribute to the communication between endodontic and periodontal issues.
- Clinical approach and differential diagnosis are crucial for identifying combined endo-perio lesions.
- The classification of these lesions includes subcategories with deeper pockets, but the focus should be on recognizing and treating the underlying issue first.
- Localized tooth-related factors, such as anatomic issues or dental restorations, can modify or predispose to gingival inflammation and periodontal disease.
- An example of a tooth-related factor is a palatal groove, which can contribute to severe bone destruction if bacteria invade the area.
- These tooth-related factors are important to consider in the context of gingival inflammation and periodontal disease.
Dental Restorations and Anatomic Factors Summary
- Certain tooth anatomic factors can make individuals more prone to developing dental issues, such as cavities, fractures, and plaque accumulation.
- Narrow root proximity can lead to bone loss and attachment loss due to inflammation induced by plaque.
- Open contacts between teeth can lead to food impaction, greater attachment loss, bone loss, inflammation, and pocketing.
- Traumatic injuries to the soft tissue and teeth can occur due to crowding or misalignment of teeth.
- Anatomical factors can influence treatment approaches, such as considering orthodontic treatment or extraction for hopeless teeth.
- Overhanging restorations and open contacts can cause inflammatory processes, requiring proper restoration and contact placement.
- Subgingival crown margins, if violating the biologic width, can lead to chronic marginal inflammation, bleeding, and sensitivity.
- Careful consideration of crown margin design and placement is crucial to avoid destructive consequences.
- The biologic width, averaging about three millimeters, is a critical consideration in dental restorations, but its measurement was based on cadavers and may differ in live human beings.
- Disputed aspects of the biologic width should be considered, but its importance in dental restorations cannot be overlooked.
- The study of the biologic width was conducted on cadavers, and the differences between cadaver and live human tissue should be considered in clinical practice.
- Understanding the impact of tooth anatomic factors is crucial in planning and executing dental restorations to ensure long-term oral health.
