A decrease in frequency of sucrose consumption is associated with an increase in caries? False
DMF represents Treatment needs, prosthetic needs, level of success of therapeutic program
When a patient with no dental carries, which of the following treatment options wouldnt be recommended Be glad the patient is caries free and just move on to the next step in the course of treatment

Once a patient has been determined to be a moderate to high risk patient they will always be at that risk level. Socio economic has no influence on the caries risk level of a person being assessed for life risk caries risk False
Caries on the proximal or interproximal surface of posterior teeth are classified as Class II
In caries detection, transillumination is required for Class IV
Smooth surface caries are found on all of the following except Occlusal surface
Compound caries involves Two tooth surfaces
Single or multiple areas of decay are referred to as Caries
Dental caries, although debatable, is considered an infection disease. It has been eradicated First statement is true, second is false
Radiographs are needed to determine class V carries? False
Root caries could also be classified as? Class V
An example of a lesion that is considered "simple" is Occlusal

An individual can be in the high or low risk category for development of dental caries. All of the following factors are low risk except Poor manual dexterity
A moderate or C-2 lesion would have a negative impact on the pulp of the tooth requiring endodontic therapy? False
The carious lesuon that is impossible on radiographs to detect the depth of decay Buccal
On a radiograph caries penetrating through enamel and Dentin over halfway through the Dentin towards the pulp is? Severe
Caries is the most common child hood disease. Most caries occur on the occlusal surface True
This caries penetrate over half way through the enamel towards the DEJ and is only seen on the enamel C-2
On a radiograph, caries appear? Radiolucent (dark)
There are four methods of caries detection. As a hygienist it is expected that you make a caries diagnosis along with your dental charting? First statement true, second false
An example of a C-1 carious lesion is an incipient caries found on a tooth that has never had any caries activity True
During caries detection the radiograph of choice is Bite wing
The depth of penetration of a carious lesion is deeper clinically than it appears on the radiograph. Therefore you may see the lesion clinically and not radiographically in early stages True
The best way to check for occlusal surface caries is with radiographs. However using a Shepards book gently checking for resistance will detect occlusal caries First statement is false, second true
When doing a visual inspection of a tooth for caries, drying the tooth is recommended to enhance the detection? True
Optimal caries detection include? Air, light, radiographs, shepard hook explorer
