| Key Hole Punch | Punches holes for tooth isolation in rubber dam |
| Discoid-cleoid Carver | For carving occlusal surface |
| Hollenback Carver | Interproximal surfaces |
| Amalgam Knife | For the removal of excess restorative material along the margin where the material and the tooth structure meet |
| Excavators | Used for removal of soft dentin, debris, and decay from the tooth |
| Hoe | Planes the walls and floors of the tooth in preparation for restoration |
| Straight Chisel | Purpose: Primarily used for cutting and shaping enamel. Situations: Effective for cavity preparations on mesial and distal surfaces of posterior teeth; used for smoothing enamel and creating retention features. |
| Bin-angle Chisel | Purpose: Designed for improved access to angled surfaces. Situations: Preferred for refining cavity preparations on mesial and distal surfaces of posterior teeth, especially in tight spaces; versatile for anterior and posterior teeth. |
| Wedelstaedt Chisel | Purpose: Combines features of a straight and angled chisel. Situations: Effective for creating smooth surfaces and refining cavity preparations; often used in anterior teeth for shaping enamel and accessing difficult angles. |
| Angle-Former Chisel | Purpose: Specifically designed to create and refine retention features in cavity walls. Situations: Ideal for forming angled walls and grooves in cavity preparations; used when retention is critical for restorations, particularly in posterior teeth. |
| Hatchet | Purpose: Used for cutting and shaping enamel and dentin with a flat cutting edge. Situations: Effective for smoothing cavity walls and refining preparations; often used to prepare and smooth mesial and distal surfaces of posterior teeth |
| Gingival Marginal Trimmer | Purpose: Smooth gingival margins. Situations: Refines gingival edges; creates bevels; accesses subgingival areas. |
| Howe Pliers | Useful for carrying cotton products to and from the oral cavity, for removing the matrix band, and for placing and removing the wedge |
| Round Burs | Go-to style for decay removal, opening tooth cavities, and creating undercuts for fillings. They are also effective in endodontic access and creating pilot holes for pediatric dentistry |
| Pear Burs | Ideal for conservative cavity preparations, ensuring minimal tooth structure removal. They provide excellent control for creating smooth cavity walls and floors, especially in composite resin restorations. |
| Spiral Burs | commonly used for bone cutting in oral surgery and implantology. Design allows for efficient removal of bone material with minimal pressure, reducing the risk of bone cracking or damage. They also offer a more comfortable experience for the patient. |
| Tapered Burs (Flat and Round) | Ideal for crown preparations, margin refining, and creating bevels in cavity preparations. They offer excellent control and visibility, making them suitable for detailed cosmetic work. |
| Football Bur | Used for smoothing and contouring occlusal surfaces, particularly in amalgam restorations. They are also effective in adjusting and polishing soft tissue contours during periodontal surgeries. |
| Torpedo Burs | Primarily used for adjusting and finishing restorations, especially in interproximal areas. Their shape allows for precise material removal without damaging adjacent tooth structures. |
| Inverted Cone Burs | Excellent for creating retentive features in cavity preparations, such as dovetails. They are also used in crown preparations to create mechanical locks and in orthodontics for bracket debonding. |
| Straight Fissure Burs | For creating initial outlines in cavity preparations and for sectioning teeth during extractions. |
| Tapered Fissure Burs | Suitable for creating convergent walls in cavity preparations and for crown and bridge preparations. |
| Wheel shaped Bur | Used for anterior crown preparations and can be used to adjust and shape occlusal surfaces. |
| Diamond Flat End Taper Bur | Used for crown preparation. |
| Diamond Round End Taper Bur | Removes tooth structure and makes mechanical retention grooves. |
| Diamond Cylinder Bur | Smooths and finishes the walls in tooth preparations. |
| Diamond Flame Shaped Bur | Makes bevels in crown preparations. |
| Diamond Round Bur | Provides access to the pulp chamber for endodontic treatment and is used to adjust and shape occlusal surfaces. |
| Gingival Marginal Trimmer | Chisel family - similar to the hatchet. Uses a beveled, curved blade to cut and refine the walls of the cavity near the gum line |
