Study Notes
Definition of Endodontics
- Endodontics is the art and science of preventing, diagnosing, and treating pulp and periradicular diseases.
Objectives of Endodontic Treatment
- Endodontic treatment aims to make the affected tooth biologically acceptable, symptom-free, and functioning without any diagnosable pathosis.
Phases of Endodontic Therapy
- Endodontic treatment involves three phases:
- Diagnostic phase: Identifying the cause of the disease and developing a treatment plan.
- Preparatory phase: Removing pulp chamber contents and shaping root canals to accommodate a three-dimensional filling.
- Obturation phase: Filling the root canal system with an inert material to ensure a fluid-tight seal.
Contraindications for Endodontic Therapy
- Modern endodontics can often address conditions previously considered contraindications. However, some conditions require careful consideration:
- Insufficient periodontal support: Endodontic treatment is planned to maintain retention.
- Vertical root fracture: Extraction may be the only solution for single-rooted teeth.
- Extensive internal or external resorption or large perforations: Surgical intervention may be needed.
- Non-restorable teeth: If treatment cannot restore functionality, extraction is often necessary.
- Teeth with unsuitable root canals for instrumentation (e.g., calcified canals): Apical surgery or extraction is the recommended resolution
- Systemic diseases contraindicating surgical endodontics: Certain systemic conditions may prevent surgical intervention.
Macroscopic Anatomy of Pulp Space
- The pulp space is the internal area of a tooth containing the pulp. The hard tissue surrounding the pulp space varies in configuration and shape.
- Anatomy includes the coronal pulp (Pulp chamber and pulp horns) and radicular pulp (Root canals).
- Specific features such as pulp chamber roof, floor, walls, pulp horns, and root canals, including anatomical apex and apical foramen.
- Types of root canal systems (e.g., class I, class II, class III) are described graphically with associated features (number of canals, orifices, and foramina).
Tooth Morphology and Pulp Space Considerations
- Detailed descriptions of the maxillary central incisor, lateral incisor, canine, first premolar, second premolar, first molar, and second molar are included in the document.
- The macroscopic anatomy and tooth morphology are described for each tooth.
- Features included in the description are a labial view (mesiodistally), proximal view (labiolingually), cross-sections, average length, root canal configuration, and outline form of access cavities.
Endodontic Cavity Preparation
- The process involves two basic steps: coronal preparation (access cavity) and radicular preparation.
- Access cavity preparation has the following key aspects: Outline form, convenience form, removal of carious dentin/defective restoration, and toilet of the cavity.
- Factors such as the size and shape of the pulp chamber and the curvature of the root canals influence access cavity preparation.
- Errors in access cavity preparation are described, with specific instances in anterior teeth and premolars and molars in both maxillary and mandibular arches
