A Class III cavity is a cavity or prepared area on the side surface (proximal surface) of a front tooth. It does not include the biting edge (incisal angle), which helps distinguish it from a Class IV cavity. Dentists use this classification to describe where decay, fracture, or an old filling is located. It most commonly applies to incisors and canines, often between teeth where floss passes.
A Class II cavity is a cavity (or prepared space) on the side surface between back teeth, usually premolars and molars. It involves the proximal surface (the contact area between teeth) and often the chewing surface as well. Dentists use the term to describe both the location of tooth decay and the shape of the prepared cavity before a filling. It is commonly restored with tooth-colored composite resin, and sometimes with other restorative materials.
A Class I cavity is a cavity located in the pits and fissures of a tooth. It most commonly occurs on the chewing surfaces of molars and premolars. It can also appear in small pits on the cheek-side or tongue-side of certain teeth. Dentists use the term to describe location and guide how a cavity is restored.
adhesive cavity prep is a way of shaping and cleaning a tooth so a bonded (adhesive) filling can attach securely. It usually aims to remove decay while keeping as much healthy tooth structure as possible. It is commonly used for tooth-colored composite fillings and some bonded inlays/onlays. It relies on dental bonding systems rather than purely “mechanical” retention (like undercuts).
extension for prevention is a traditional concept in restorative dentistry that describes widening a tooth preparation into nearby pits and fissures that are considered more likely to decay. In plain terms, it means “extend the repair a bit farther” so the final restoration ends on tooth areas that are easier to keep clean. It is most commonly discussed in the context of treating occlusal (chewing-surface) cavities on premolars and molars. Modern dentistry may apply the idea more selectively, depending on the patient’s cavity risk and the materials used.
MID stands for minimally invasive dentistry. It is an approach that aims to preserve as much natural tooth structure as possible. It is commonly used in preventive care and in treating early or moderate tooth decay. It often relies on adhesive materials (bonded fillings and sealants) rather than large mechanical preparations.
minimally invasive dentistry is a clinical approach that aims to preserve as much natural tooth structure as possible. It focuses on early detection, prevention, and small, targeted repairs instead of extensive drilling. It is commonly used in managing early tooth decay (caries), worn enamel, and small defects. It often relies on adhesive materials, sealants, and conservative preparation designs.
cavity preparation is the process of cleaning and shaping a tooth so it can be repaired with a dental material. It is most commonly performed when treating tooth decay (cavities) or replacing an old, damaged filling. The goal is to create a clean, stable surface and a shape that helps the restoration stay in place. It is a core step in restorative dentistry and is often followed by placing a filling or an indirect restoration.
caries dye is a colored liquid or gel used during cavity preparation to help highlight tooth structure that may be carious (decayed). It is most commonly used while removing decay from dentin (the layer under enamel) before a filling is placed. The dye is applied briefly and then rinsed, leaving stained areas that can guide further cleaning. It is a chairside aid used in restorative dentistry, not a filling material itself.
A slow-speed round bur is a small, ball-shaped cutting instrument used in dentistry. It fits into a slow-speed handpiece (a low-RPM dental drill) to remove or refine tooth structure. It is commonly used during cavity cleanup, caries (decay) removal, and restorative procedures. Different sizes and materials are selected depending on the tooth, the location, and the task.
