Study Notes
Endodontics Definition
- Endodontics is the science of pulp and periradicular disease prevention, diagnosis, and treatment.
Endodontic Treatment Objectives
- Render the affected tooth biologically acceptable.
- Eliminate symptoms.
- Enable the tooth to function without any diagnosable disease.
Phases of Endodontic Therapy
- Diagnostic Phase: Identifying the cause of the disease and developing a treatment plan.
- Preparatory Phase: Removing the contents of the pulp chamber and root canals, reshaping the root canal space for filling.
- Obturation Phase: Filling the root canal system with an inert material to create a fluid-tight seal.
Contraindications for Endodontic Therapy
- Insufficient periodontal support for the tooth.
- Vertical root fracture.
- Extensive internal or external resorption in teeth with significant perforations that cannot be surgically treated.
- Non-restorable teeth that will not function properly after treatment.
- Teeth with unsuitable root canals for instrumentation (like calcified canals).
- Systemic diseases contraindicating surgical endodontics.
Tooth Morphology and Pulp Space
- Pulp space is the entire internal space within the tooth containing the pulp.
- The pulp chamber is located in the crown of the tooth.
- The pulp chamber has a roof (dentin covering the pulp chamber), a floor (dentin in the furcation area) and walls (mesial, distal, buccal, and lingual).
- Pulp horns are accentuations of the pulp chamber under cusps or developmental loops.
- Root canals are the portion of the pulp cavity that extends into the root of the tooth.
- Anatomical apex is the most tapered portion of the root.
- Apical constriction is the narrowest point in the root canal.
- Apical foramen is where the neurovascular bundle exits the root.
- Lateral canals are canals that extend laterally from the main canal to the surface of the tooth's root.
- Root canal orifice is the opening from the pulp chamber to the root canal.
- Different tooth types have varying root canal configurations (Weine classification: Class I, II, III, IV, V, VI).
Maxillary Central Incisor, Lateral Incisor, Canine, First Premolar, Second Premolar, First Molar, and Second Molar (Morphology and Structure)
- Detailed descriptions of the pulp chamber, root canal configurations, anatomical landmarks, and dimensions are provided for each tooth type. This includes buccal, proximal, and cross-sectional views.
- Root canal configurations vary between classes (class I typically has one canal, class II may have two canals).
- The outline form of the access cavity is described (oval, triangular, etc.) for all posterior teeth.
Endodontic Cavity Preparation
- Purpose: Efficiently uncovering the roof of the pulp chamber and providing access to the apical foramina.
- Factors affecting outline form: pulp chamber size, shape, and the number/position of canals.
- Importance of preserving tooth structure and ensuring straight-line access for proper instrumentation.
- Principles of access cavity preparation are discussed (e.g., outline form, convenience form) and the steps are detailed.
- Common mistakes/errors associated with access cavity preparation in anterior, premolar and molar teeth are detailed (e.g., perforation, gouging, missing/extra canals, underextended/overextended prep's).
