Access cavity
Creating a perfect access cavity is the first and often most challenging step of endodontic treatment. It is divided into two stages: the primary cavity (access to the pulp chamber) and the secondary cavity (access to the root canal system). Success depends on creating sufficient space and unobstructed vision. Komet provides a comprehensive range of instruments for this purpose.
EndoGuard – Perfect View and Safety
Features
- Non-cutting tip to protect the pulp chamber floor
- Tapered design to avoid undercuts
- Efficient cross-cut toothing for smooth dentin removal
Benefits
- Improved view of the pulp chamber and canal orifices
- Minimally invasive and safe
- Reduces risk of canal transportation and file fracture
- Preserves hard dental substance
The EndoGuard ensures efficient and safe access cavity preparation immediately after opening the pulp chamber.
EndoTracer – Accurate Retrieval of Canals
Features
- Long, slender neck for unobstructed view
- Available in lengths 31 mm and 34 mm, sizes 004–014
- Petite round burs for minimally invasive shaping
Benefits
- Facilitates exposure of pulp chamber floor and hidden canals
- Ideal for microscope-assisted procedures
- Allows precise, controlled shaping of isthmuses and canal entrances
EndoExplorer – Minimally Invasive Access
Features
- Tungsten carbide construction for concentric runout and precision
- Tapered head for controlled guidance
- Sharp, fast-cutting toothing
Benefits
- Conserves cervical dentin and overall tooth structure
- Enhances efficiency and control under magnification
- Supports minimally invasive approach for long-term tooth prognosis
System Overview
- EX1: exposes pulp chamber floor, root canal entrances, obliterated canals, and post/instrument fragments
- EX2: removes dentin overhangs, prepares access cavity, cleans gutta-percha and sealer residues
Step-by-Step Access Cavity Preparation
- Initial shaping of the access cavity and exposure of canal entrances with EX2
- Enlargement of the access cavity towards the cavity margin with EX2
- Exposure of isthmuses between canals with EX1
- Preparation of the root canal system
Best Practices
- Use magnification and illumination
- Assess pulp chamber anatomy with recent radiographs or CBCT scans
- Remove existing restorations if necessary
- Follow the Law of Centrality, Concentricity, and Symmetry for precise access
- Refine dentine overhangs to ensure smooth, straight-line access
- Identify canal entrances using developmental lines on the pulp chamber floor
Komet’s access cavity instruments provide safe, efficient, and precise preparation, laying the foundation for successful endodontic treatment.
