Clinic theory Exam 2025 With 100%
Correct Answers
Class I— (anterior and posterior)
-pit and fissures of teeth
(Occlusal pit and fissure of molar/premolar)
(Lingual pit max molar)
Class II— (interproximal posterior)
Proximal surfaces of posterior teeth (premolar/molar)
Class III— (anterior)
-interproximal surface of anterior teeth (incisors/canines)
Class IV— (anterior)
-incisal edge and interproximal surface of anteriors (incisors/canines)
Class V— (anterior/posterior)
-smooth surface decay
-gingival 1/3 or facial and lingual surface of any teeth
-root surface near CEJ
Class VI— (anterior/posterior)
-incisal edge of anterior teeth (incisors/canines)
-cusp tips of posterior teeth - CORRECT ANSWER✔✔Blacks classification
,-initial/recurrent decay
-replacement of broken/fractures restorations
-abrasion/wearing away of tooth structure
-erosion - CORRECT ANSWER✔✔Conditions that indicate need for restorative dentistry
Removing diseased tooth structure while leaving limited amount of healthy tooth structure to
maintain restoration - CORRECT ANSWER✔✔Cavity preparation
Aid in retention of restorations when extensive tooth structure is missing.
-used for vital teeth
-post for non vital teeth
-one pin per missing cusp
Must use dental dam (can fall in throat) - CORRECT ANSWER✔✔Retentive pins
Matrix band— •Provides temporary wall for class II, III and IV restorations
Posterior matrix— (amalgam and composite restorations)
-universal retainer (toffilmire retainer)
-hold matrix band in position
-positioned from buccal surface of tooth - CORRECT ANSWER✔✔Matrix system
Universal band— Class II when proximal box is prepared to a minimal depth and width
Extension band— Class II with gingival extensions when height of contour of band cannot
exceed height of tooth. - CORRECT ANSWER✔✔Universal vs extension band
,-allow good contour
-hold hand tight against tooth
-eliminates overhang
-against side where wall is missing
-base of triangle towards gingiva - CORRECT ANSWER✔✔Wedges
Axial wall— internal wall/surface of prepared tooth.
-runs parallel to long axis of tooth
Pulpal wall— (pulpal floor) internal wall/surface of tooth when it's perpendicular to long axis of
tooth - CORRECT ANSWER✔✔Axial and pulpal wall
Automatix system— •no retainer necessary
-band already formed in circle. Has coil like locking loops
T bands— •copper shaped T bands
-no retainer needed
-used for primary molars
Sectional matrices— •used with tension ring for tight contact
-used for posterior composite resin - CORRECT ANSWER✔✔Alternative matrix systems
-Class III and IV caries should be restored with composite (anterior)
Operator will open through lingual surface to reduce size from facial aspect
, If decay is subgingival a tissue retraction rubber dam clamp used to access under gingiva -
CORRECT ANSWER✔✔Composite resin
Smooth outline no angles
-location of lesion dictate what material will be used
-if moisture is an issue and it's posterior the operator will use amalgam
•proximity of gingiva may result in retraction to keep area dry/clean (retract with cervical
rubber dam clamp) - CORRECT ANSWER✔✔Preparation for class V restoration
Polymerization— resin material changes from pliable to hardened restoration.
Polymerization occur through
1) light cure
2) self cured - CORRECT ANSWER✔✔Polymerization
—known as Celluloid strip or Mylar strip
used with anterior composite resin or glass ionomer
-composite resin has inorganic filler particles that can be scratched or marked by stainless steel
No retainer needed - CORRECT ANSWER✔✔Anterior matrix system
Dycal and glass ionomer liners used under composite resin.
-available in self and might cure
