Which of the following statements are true regarding microcracks and instrumentation?
*
Microcracks are reliable indicators of fracture initiation in vivo.
Microcracks seen in lab settings are identical to in vivo cracks.
All instrumentation systems reduce post-op pain equally.
aPDT creates high-frequency ultrasonic waves to break up bacteria.
Patient pain on biting is always indicative of irreversible pulpitis
Consider these statements about diagnostic techniques and treatment:
*
Material choice is the only factor determining DPC outcome.
Gingival crevicular fluid is a weak surrogate for periapical inflammation.
Cracked teeth often present with pain on release rather than pressure.
Laser disinfection is adjunctive and not a replacement for chemo-mechanical preparation.
Lasers replace the need for mechanical debridement entirely.
Regarding the diagnosis and treatment of cracked teeth, which statements are correct?
*
Gingival crevicular fluid is a definitive measure of pulpal inflammation.
Naked eye examination is sufficient for detecting all crack types.
CBCT is useful for detecting vertical bone loss associated with cracks.
Cracked teeth typically hurt only under constant pressure.
Full-coverage crowns help stabilize cracks in teeth with vital pulp.
Which of the following statements are accurate regarding materials and detection?
*
Calcium hydroxide is bioactive and induces dentine bridge formation more predictably than HCSC.
CBCT routinely detects fractures under 100 μm.
Full-coverage crowns are contraindicated in managing cracks.
Bruxism has no correlation with cracked teeth.
Peskersoy et al.'s study had a disproportionate impact on the Pulp Cap meta-analysis.
Consider the following statements on instrumentation and diagnostics:
*
Conventional instrumentation always causes less post-op inflammation than conservative methods.
Dentinal microcracks observed in vitro may be artefacts from experimental procedures.
PIPS uses an Er:YAG laser to activate irrigants in root canals.
Laser-activated irrigation has no effect on biofilm disruption.
Operator experience and aseptic technique are critical variables in pulp capping outcomes.
Regarding root fractures and crack progression, which are true?
*
Early-stage VRFs commonly begin at the coronal third of the root.
Early-stage vertical root fractures (VRFs) often originate in the mid-root region.
CBCT is the gold standard for detecting microfractures.
CBCT may not detect fractures narrower than 150 μm.
VRFs propagate from the root surface inward toward the canal.
Which statements about pulp capping and material success are valid?
*
DPC success depends on factors beyond just material choice.
PIPS relies on sodium hypochlorite laser excitation for effect.
Hydraulic calcium silicate-based cements (HCSC) show higher success rates than calcium hydroxide in DPC.
Cracks like to stay off the radar but don’t dismiss them outright.
Calcium hydroxide is consistently superior to HCSC in DPC success rates.
Evaluate these statements regarding diagnostic aids and laser therapy:
*
Magnification improves the detection of fine structural cracks.
CBCT consistently visualizes craze lines and minor enamel cracks.
Transillumination can help visualize cracks within the tooth structure.
Light curing units are too weak for effective transillumination.
CBCT is highly sensitive for visualizing fine cracks directly.
Consider the following about crack symptoms and mechanisms:
*
Cracked teeth often present with vague or shifting pain locations.
Pain at rest is a hallmark of cracked tooth syndrome.
Pain on release (not pressure) is a key indicator of cracked teeth.
Transillumination is obsolete and has no role in crack detection.
History of clenching or grinding is often irrelevant in diagnosis.
Assess these statements about lasers and healing:
*
Statistical differences in inflammatory markers resolved by 72 hours.
Laser-activated irrigation improves biofilm disruption compared to traditional methods.
CBCT is useful for detecting inflammatory mediators in real time.
Operator technique has minimal impact on post-op pain.
aPDT uses a photosensitiser and light to generate reactive oxygen species for disinfection.
