Bis-acryl composite temporary crowns offer good aesthetics, sufficient strength, and are easily trimmed and polished for anterior temporary restorations.

Which test is most reliable for assessing pulp vitality in a traumatised anterior tooth?

Answer: Electric pulp test combined with cold test

Combining electric pulp testing with thermal (cold) testing improves diagnostic accuracy for pulp vitality, especially important after trauma.

What is the recommended approach when a patient presents with bruxism requiring restorative treatment?

Answer: Occlusal splint therapy before and alongside restorations

An occlusal splint manages parafunctional loading and allows the clinician to trial the restored occlusal vertical dimension before committing to definitive restorations.

In the Index of Treatment Need (IOTN), which component assesses aesthetic impairment?

Answer: Aesthetic Component (AC)

The IOTN Aesthetic Component uses a 10-photograph scale to grade the aesthetic impact of the malocclusion and determine treatment need.

What is the most common reason for failure of tooth-coloured restorations in primary teeth?

Answer: Secondary caries and marginal breakdown

Primary teeth restorations commonly fail due to secondary caries developing at margins, often related to high caries risk and difficulty achieving isolation.

Which term describes the ability of a restorative material to resist permanent deformation under load?

Answer: Hardness

Hardness is the resistance of a material to permanent indentation or deformation, critical for restorative materials that must withstand occlusal forces.
