Question 1

A patient presents with a deep carious lesion on a lower first molar with symptoms of reversible pulpitis. What is the most appropriate treatment approach?

Immediate root canal treatment Stepwise excavation or selective caries removal to avoid pulp exposure, followed by placement of a well-sealed restoration Extraction and replacement with an implant Prescribe antibiotics and review in one month

Correct Answer:

Stepwise excavation or selective caries removal to avoid pulp exposure, followed by placement of a well-sealed restoration

Question 2

When assessing a patient for a fixed dental prosthesis (bridge), what is Ante's Law and what is its clinical significance?

It states that the number of pontics must equal the number of abutments It states that the total periodontal ligament area of the abutment teeth should be equal to or greater than that of the teeth being replaced — it helps determine whether abutment teeth can support the bridge It determines the shade selection for the bridge It specifies the minimum connector dimensions for a bridge

Correct Answer:

It states that the total periodontal ligament area of the abutment teeth should be equal to or greater than that of the teeth being replaced — it helps determine whether abutment teeth can support the bridge

Question 3

What are the essential features of an ideal Class II cavity preparation for a composite resin restoration?

Flat floor, undercuts for retention, 90-degree cavosurface angles, and maximum extension Conservative preparation following the extent of caries, rounded internal line angles, enamel bevels at the occlusal margin (no bevel gingivally), adequate access for placement and curing, and a clear gingival margin for matrix adaptation No cavity preparation is needed — composite bonds to any surface Sharp internal line angles, dovetail retention, and extension for prevention to all fissures

Correct Answer:

Conservative preparation following the extent of caries, rounded internal line angles, enamel bevels at the occlusal margin (no bevel gingivally), adequate access for placement and curing, and a clear gingival margin for matrix adaptation

Question 4

A patient presents with localised aggressive periodontitis affecting the first molars and incisors in a 22-year-old. What microorganism is most commonly associated with this condition?

Streptococcus mutans Aggregatibacter actinomycetemcomitans Candida albicans Staphylococcus aureus

Correct Answer:

Aggregatibacter actinomycetemcomitans

Question 5

What is the difference between a removable partial denture designed with a bounded saddle versus a free-end saddle, and how does this affect support?

There is no clinical difference between bounded and free-end saddles A bounded saddle has abutment teeth on both sides of the edentulous span (tooth-supported); a free-end saddle extends distally with no posterior abutment (mucosa-supported distally), requiring careful consideration of support, retention, and path of insertion to manage differential tissue support A free-end saddle is always contraindicated in partial denture design Bounded saddles require implants for support; free-end saddles do not

Correct Answer:

A bounded saddle has abutment teeth on both sides of the edentulous span (tooth-supported); a free-end saddle extends distally with no posterior abutment (mucosa-supported distally), requiring careful consideration of support, retention, and path of insertion to manage differential tissue support
