• Removal of remaining carious dentin

• Finishing of cavity walls and margins

Which form in cavity preparation describes the shape of the internal form of the preparation?

• External outline form

• Internal outline form

• Resistance and retention form

• Convenience form

What is the aim of placing the margins of cavities in sound enamel?

• To promote caries recurrence

• To weaken the tooth structure

• To provide better esthetics

• To increase stress concentration

Which areas are considered self-immune areas in cavity preparation?

What should be included in the outline form regarding enamel?

When should adjacent cavities be joined into a single cavity?

• When the enamel is weak

What is the purpose of including carious dentin in cavity preparation?

• To increase pulpal irritation

• To prevent lateral spread of caries along DEJ

• To weaken the tooth structure

In proximal cavities, what is the purpose of freeing the contact with the adjacent tooth?

• To make the cavity margin convenient for brushing

• To make the cavity margin inaccessible

• To weaken the tooth structure

• To promote caries development

What is the junction between the occlusal and proximal cavity called?

• Uniform curve
