Curettage includes the use of a curette for a dental procedure. It is used for scraping and has effectively been applied in the treatment of periodontitis. Gingival curettage is considered a surgical procedure. It uses a curette to, from a periodontal pocket, remove soft tissue lining.

Hand cutting instruments allow the dentist, dental hygienist or dental assistant to remove decay manually from teeth for final restoration. The hand cutting instruments include the chisel, excavator, elevator, gingival margin trimmer, hand piece, hoe, hatchet, scalar, and Wilson.
The chisel meaning. a flat-bladed sharp instrument with a beveled cutting edge and a handle with a hammer or mallet used to cut or shape wood, stone, metal, bone, and cartilage in orthopedic surgery.
Standard instruments are made with the highest quality materials — they're made with austenitic 316 steel, also referred to as surgical steel or marine-grade surgical steel.
This scaler is used to remove plaque and calculus from the tooth surface. The sickle scaler tip can be used to remove calculus from the developmental grooves and blood grooves in canine teeth. This scaler is used to remove plaque and calculus from the tooth surface.
Spoon Excavator is used for cutting and removing the carious dentine of a decayed tooth. A spoon excavator is used to clean out and shape a carious cavity before filling it.
A hand instrument with the cutting edge of the blade at right angles to the long axis of the handle. A periodontal hoe is used for removing calculus and other deposits from the tooth surface; it has a straight cutting edge which does not conform to concave root surfaces.
For the removal of supragingival calculus. The chisel-like working end used by pushing. The jacquette working end used by pulling.
Periodontal files are used for debridement in deep pockets. They are excellent for breaking up tenacious or large calculus deposits. The design has a series of parallel blades on a flat head that can crush the deposits (Figures 47a‑b).
curettage: Scraping and cleaning the walls of a real or potential space, such as a gingival pocket or bone, to remove pathologic material.
Use hoe scalers to remove supra- and subgingival calculus. These instruments are excellent for cleaning deep, narrow pockets and concave root surfaces and can be used with both vertical and horizontal techniques.
A dental explorer or sickle probe is an instrument in dentistry commonly used in the dental armamentarium. A sharp point at the end of the explorer is used to enhance tactile sensation. In the past it was usual for dentists to use the explorer to probe teeth for the presence of cavities.
One gingival margin trimmer is used in the distal box of a class II preparation to plane the cavo surface margin and one is used in the mesial box. To plane the gingival cavo surface margin, place the instrument in the center and move it from the bevel side to non-bevel side.
Composite and plastic filling instruments, also known as placement instruments, are designed for placing and contouring pliable restorative materials into cavity preparations and other dental procedures.
Enamel is the thin outer covering of the tooth. This tough shell is the hardest tissue in the human body. Enamel covers the crown which is the part of the tooth that's visible outside of the gums. Because enamel is translucent, you can see light through it.
Gingival hyperplasia is an overgrowth of gum tissue around the teeth. There are a number of causes for this condition, but it's often a symptom of poor oral hygiene or a side effect of using certain medications.
In dentistry, a tool to compress amalgam into a cavity preparation.
An instrument used to transfer amalgam alloy to a tooth cavity. It has a hollow working end at an angle to the long axis of the instrument through which amalgam is expelled by a plunger mechanism.
bevel. noun. Definition of bevel (Entry 2 of 3) 1 : an instrument consisting of two rules or arms jointed together and opening to any angle for drawing angles or adjusting surfaces to be cut at an angle. 2a : the angle that one surface or line makes with another when they are not at right angles.
A bevelled edge (UK) or beveled edge (US) is an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage they are often interchanged, while in technical usage they may sometimes be differentiated as shown in the image at right.
The placement of a cavosurface margin bevel on the enamel margins of anterior composite preparations traditionally has been recommended to enhance retention and for esthetic reasons, as bevels result in a gradual transition between the restoration and the tooth.
Cavosurface angle is the angle of the tooth structure formed by the junction of a prepared wall and the external surface.[9] Various theories have been proposed for the orientation of the walls and the corresponding AMA.
Class II cavitiesClass II carious lesions occur on proximal surfaces of premolars and molars. They may occur in combination with occlusal (Class I) caries or they may occur alone. In situations where the presence of caries is on the occlusal as well as the proximal surface, a two-surface cavity is prepared.
The placement of a cavosurface margin bevel on the enamel margins of anterior composite preparations traditionally has been recommended to enhance retention and for esthetic reasons, as bevels result in a gradual transition between the restoration and the tooth.
A reverse bevel refers to cabinet doors that do not require knobs or pulls to be opened. The angle of the cut allows homeowners to open the cabinet by pulling on the top of the door. Reverse beveled edges on cabinet doors do require different hinges if they are used on that edge of the door.
Cusp capping is the process of using composite fillings to replace the cusps in teeth. A cusp is a hard protrusion on a tooth. The cusp sits higher than the rest of the tooth and therefore is the first point of contact when biting.
the presence of a bevel significantly increases marginal adaptation when placing composite restorations. The presence of a bevel also has been shown to mitigate the effect of polymerization shrinkage, which again will increase the seal and longevity of the marginal interface and decrease post operative sensitivity.
