Direct answer: Gold Cura EX-24 Safe-Ended Diamond Bur FG is a tapered, side-cutting dental diamond bur with a non-cutting or reduced-cutting terminal tip. It is commonly selected after initial access penetration to deroof and laterally extend an endodontic access cavity, refine pulp-chamber walls and reduce the risk of unintentionally cutting into the chamber floor with the tip. Each pack contains 5 EX-24 burs.

| Shank | FG / friction grip for a compatible high-speed dental handpiece |
| Pack size | 5 identical EX-24 burs |
| Intended user | Trained dental professionals |
What Does “Safe-Ended” Mean?
Safe-ended does not mean that the entire bur cannot cut. The lateral diamond-coated surfaces remain active. The terminal tip is designed to reduce or avoid cutting at the end of the bur, helping the clinician refine walls or remove the remaining chamber roof while reducing the risk of tip-directed penetration into the pulpal floor. Direct vision, correct orientation and controlled lateral movement remain essential.
When to Use the EX-24 Safe-End Bur
EX-24 is the only size offered on this page, so there is no small-to-large size selection. Choose it when the clinical task matches its safe-ended tapered geometry:
- After initial access entry: establish penetration with an appropriate round or access bur before introducing the safe-ended instrument.
- For deroofing the pulp chamber: use controlled lateral or outward brushing strokes to remove remaining roof structure under direct visualisation.
- For access-cavity extension: extend the cavity laterally and refine the internal walls while keeping the non-cutting tip oriented toward the chamber floor.
- For straight-line access refinement: remove restrictive dentinal shelves or wall irregularities when clinically indicated without using the tip to drill apically.
- For selected prosthodontic preparation: use only where a safe-end profile is appropriate and the Gold Cura instructions support the indication.
When Not to Use EX-24
- Do not use it as the primary penetration bur for entering an intact chamber.
- Do not assume the side surfaces are non-cutting.
- Do not press the terminal tip into the chamber floor or root-canal walls.
- Do not use without adequate visibility, orientation and knowledge of the expected pulp-chamber anatomy.
- Do not transfer dimensions, RPM limits or sterilisation instructions from another EX-24 manufacturer to Gold Cura.
EX-24 vs a Round Access Bur
| Instrument | Primary role | Typical movement |
|---|---|---|
| Round diamond bur | Initial penetration and opening of the access cavity | Controlled entry according to tooth anatomy |
| EX-24 safe-ended bur | Deroofing, lateral extension and wall refinement after entry | Lateral or outward brushing while the safe tip is directed toward the chamber floor |
Clinical Selection and Use Guide
- Review anatomy and imaging. Plan the access outline and anticipate chamber-floor depth before cutting.
- Isolate and obtain visibility. Use appropriate clinical isolation and illumination.
- Create the initial entry. Use the instrument selected for penetration rather than forcing the safe-ended bur through intact structure.
- Introduce EX-24 only after access is established. Orient the safe tip toward the chamber floor.
- Cut with the sides. Use light lateral or outward brushing movements to remove the roof and refine walls.
- Inspect continuously. Stop and reassess whenever anatomy is unclear.
- Use appropriate cooling, speed and processing. Follow the Gold Cura packaging or supplied instructions.
Frequently Asked Questions
What is an EX-24 safe-ended diamond bur?
It is a tapered FG diamond bur whose sides cut while the terminal tip is designed to reduce or avoid end cutting.
What is EX-24 mainly used for?
It is commonly used to deroof and laterally extend an endodontic access cavity and to refine pulp-chamber walls after the initial entry has been created.
Does the whole bur have a non-cutting surface?
No. The safe-end feature applies to the terminal tip; the lateral surfaces remain cutting surfaces.
Can EX-24 be used for initial penetration?
It is generally selected after initial access penetration rather than as the primary entry bur.
How should EX-24 be moved?
Use controlled lateral or outward brushing strokes under direct visualisation, keeping the safe tip oriented toward the chamber floor.
Can EX-24 prevent every perforation?
No. It can reduce tip-directed cutting risk, but incorrect orientation, excessive pressure or poor anatomical awareness can still cause damage.
Is EX-24 also used in crown and bridge preparation?
Some comparable listings describe crown and bridge use. Apply that indication only when supported by the Gold Cura instructions and the planned preparation.
How many burs are included?
Each pack contains five identical EX-24 burs.
Which handpiece is required?
EX-24 is an FG friction-grip bur for a compatible high-speed dental handpiece.
What are the exact dimensions and maximum RPM?
Comparable EX-24 products do not always publish identical ISO references or dimensions. Confirm the Gold Cura specification from the packaging or supplied technical documentation.
Can EX-24 be sterilised and reused?
Follow the cleaning, disinfection, sterilisation, reuse and replacement instructions supplied with the product.
