1A 28-year-old patient presents with a moderate Class II carious lesion on the mesial of tooth #14 (upper first premolar). After caries removal, the proximal box has a gingival margin located 1 mm coronal to the cementoenamel junction. Which restorative material and technique best restores proximal contact and contour?
A.Direct composite resin placed with a sectional matrix and separating ring
B.Conventional amalgam packed against a flat Tofflemire band
C.Glass ionomer cement placed in bulk without a matrix
D.Compomer placed without rubber dam isolation
Explanation: A sectional matrix with a separating (G-ring) system creates the firm tooth separation and anatomic contour needed to achieve a tight proximal contact in posterior composite restorations. This is the contemporary evidence-based technique for Class II direct composites.
2Which of the following is the primary indication for using a glass ionomer cement (GIC) restoration rather than composite resin?
A.A large stress-bearing Class IV restoration on a central incisor
B.A root-surface (Class V) cervical lesion in a high-caries-risk patient
C.An MOD restoration on a heavily loaded molar
D.An aesthetic veneer on a discolored anterior tooth
Explanation: Glass ionomer chemically bonds to tooth structure and releases fluoride, making it well suited to non-stress-bearing cervical/root lesions, particularly in high-caries-risk patients. Its fluoride release helps inhibit secondary caries.
3During acid-etch bonding with a total-etch (etch-and-rinse) adhesive on dentin, over-drying the etched dentin surface most commonly results in which problem?
A.Premature setting of the bonding resin
B.Excessive fluoride release into the pulp
C.Collapse of the collagen network and reduced hybrid layer formation
D.Increased enamel etch depth
Explanation: Etched dentin must be kept slightly moist ('wet bonding') so the exposed collagen network stays expanded for resin infiltration. Over-drying collapses the collagen, preventing proper hybrid layer formation and weakening the bond.
4A patient has generalized cervical wear with smooth, wedge-shaped notches and no plaque or caries. The lesions are associated with a history of vigorous horizontal toothbrushing. What is the most appropriate term and first-line management?
A.Caries; place full-coverage crowns on all affected teeth
B.Erosion; prescribe systemic fluoride tablets
C.Attrition; provide an occlusal splint as the sole treatment
D.Abrasion; modify brushing technique and restore symptomatic lesions
Explanation: Wedge-shaped non-carious cervical lesions from horizontal toothbrushing are classic abrasion. Management focuses on correcting the causative habit (soft brush, modified technique) and restoring sensitive or deep lesions, usually with GIC or composite.
5When placing a deep composite restoration close to the pulp (remaining dentin thickness under 0.5 mm) with no pulp exposure, which liner is most appropriate beneath the restoration?
A.A thin layer of resin-modified glass ionomer or calcium silicate liner over the deepest area
B.A full-thickness amalgam base
C.Eugenol-containing zinc oxide cement under the bonded composite
D.No liner; bond composite directly to near-pulpal dentin
Explanation: For deep cavities approaching the pulp, a biocompatible liner such as resin-modified glass ionomer or calcium silicate (e.g., MTA/Biodentine type) is placed over the deepest dentin to protect the pulp before bonding the composite.
6A composite restoration placed two weeks ago is causing pain on biting that resolves quickly once the patient releases the bite. There is no spontaneous or lingering pain. What is the most likely cause?
A.Irreversible pulpitis requiring root canal treatment
B.A high (premature) occlusal contact on the restoration
C.Acute apical abscess
D.Cracked tooth with pulp necrosis
Explanation: Pain only on biting that disappears immediately upon release, without lingering or spontaneous pain, typically indicates a hyperocclusion (high spot). Adjusting the occlusion with articulating paper usually resolves it.
7Which classification describes a carious lesion involving the proximal surfaces of anterior teeth WITHOUT involving the incisal angle?
A.Class V
B.Class IV
C.Class III
D.Class I
Explanation: In G.V. Black's classification, Class III lesions involve the proximal surfaces of incisors and canines without including the incisal angle. Once the incisal angle is involved, the lesion becomes Class IV.
8Polymerization shrinkage stress in posterior composite restorations is best minimized by which clinical approach?
A.Eliminating the bonding agent to reduce stress at the interface
B.Filling the entire cavity in a single bulk increment of conventional composite
C.Using a high-intensity cure for a very short total time
D.Incremental layering with adequate curing of each increment
Explanation: Incremental placement reduces the configuration (C-)factor effects and limits cumulative shrinkage stress at the tooth-restoration interface, lowering the risk of marginal gaps and postoperative sensitivity. Each increment is cured before the next is added.
9A patient reports sharp, short sensitivity to cold and sweet on a tooth with an exposed cervical dentin surface but no caries or pulpal pathology. According to the hydrodynamic theory, what is the mechanism of this dentin hypersensitivity?
A.Fluid movement within open dentinal tubules stimulating pulpal nerves
B.Direct bacterial invasion of the pulp
C.Demineralization of the enamel rods
D.Inflammation of the periodontal ligament
Explanation: The hydrodynamic theory holds that stimuli (cold, sweet, air) cause rapid fluid movement in exposed, patent dentinal tubules, which deforms odontoblastic processes and activates A-delta nerve fibers, producing a sharp, short pain.
10What is the recommended management of a 'sticky fissure' (questionable occlusal lesion) on a permanent molar when the enamel surface is intact, radiographs show no dentin involvement, and the patient is at low caries risk?
A.Place an immediate MOD amalgam restoration
B.Apply a resin-based fissure sealant and monitor
C.Perform prophylactic root canal therapy
D.Extract the tooth to prevent caries spread
Explanation: A questionable occlusal lesion with intact enamel and no radiographic dentin involvement in a low-risk patient is best managed conservatively with a fissure sealant and monitoring, preserving sound tooth structure (minimally invasive dentistry).
