What are the cavity classifications?

What are the cavity classifications?

Depending on its extent, decay is classified as incipient, moderate, advanced or severe. In order to understand these categories, it helps to have general knowledge about tooth anatomy.

What are the three types of cavities?

The Three Types of Cavities

• Smooth Surface Cavities. This type of decay comes from regular eating and drinking and can appear even on the sides of your teeth.
• Pit and Fissure Cavities. This decay happens on the top of your teeth, where your chewing is concentrated.
• Root Cavities.

What is class V cavity?

Class V: Cavity on the cervical third of the facial or lingual surfaces of any tooth (Think of the neck of the tooth) Class VI: Cavity on incisal edges of anterior teeth and cusp tips of posterior teeth (Class VI corresponds to the very top surface of a tooth)

Why are cavities classified?

Cavity classification system Dental caries, or cavities, as we commonly call them, are caused by a breakdown of tooth enamel, which is the result of bacteria on the teeth that breakdown sugars and produce acid that’s destructive to tooth enamel.

What is a 4 surface cavity?

A four-surface silver filling is typically undertaken when cavities are found on what is referred to as the interproximal surface of the tooth. Simply put, these are the surfaces that butt up against the surface of another tooth.

What is class 3 dental?

Class 3: Patients who require urgent or emergent dental treatment. Class 3 patients normally are not considered to be worldwide deployable. Treatment or follow-up indicated for dental caries, symptomatic tooth fracture or defective restorations that cannot be maintained by the patient.

What is a Class 3 cavity?

Class III. This decay occurs on the surfaces between the front teeth, but it does not involve the cutting edges of the teeth. Similar to Class II, this classification of decay is not visible.

What is a Class 6 cavity?

Class VI cavities Class VI lesions occur on incisal surfaces of anterior teeth and cusp tips of canines, premolars and molars due to attrition. Typically the lesion will have the appearance of a worn down central dentin island surrounded with ragged enamel periphery.

What is tooth decay Class 4?

Tooth decay is the breakdown of tooth enamel. It can lead to holes in the teeth called cavities. Tooth decay is caused by bacteria in the mouth. These bacteria make a sticky substance called plaque that can eat away at a tooth’s enamel.

What is a Class 4 dental?

– Class 4 patients (an additional classification) are patients who require periodic dental examinations or patients with unknown dental classifications. Class 4 patients are nor- mally not considered to be worldwide deployable. All re- cruits are class 4 until they have had an examination.

What is a 3 surface filling?

A three-surface filling will cover three of the following surfaces: occlusal (top of the tooth), mesial (front of the tooth), distal (back of the tooth), facial (side of the tooth facing the cheek), and lingual (side of the tooth facing the tongue).

What are the different cavity classifications?

Class I cavities are in the pits and fissures (cracks) in your teeth. Class II cavities are on the sides and chewing surfaces of your premolars and molars in the back of your mouth. Class III cavities involve the sides of your incisors and canine teeth in the front of your mouth (which you use to bite and chew food).

What is a Class V cavity?

Class V cavities are on the surface of the teeth closest to the face or tongue and do not involve any pits or grooves. Class VI cavities are on the edges of the front teeth, or on the part of the back teeth that touch the jaw.

What does Class 2 mean for dental care?

Class 2: Patients with a current dental examination, who require non-urgent dental treatment or reevaluation for oral conditions, which are unlikely to result in dental emergencies within 12 months. Class 2 patients are worldwide deployable.

What is a Class 3 dental restoration?

The class III restoration is nominally a “one-surface” restoration on the proximal contacting surface of the tooth. It is generally formed with composite resin or ionomer cement.
