(EFDA & Radiology) |Restorative
Procedures|Complete Answers
**What is the primary purpose of restorative dental procedures?**

Restorative dental procedures aim to restore function and aesthetics to damaged teeth.

Restorative dental procedures are designed to repair tooth structure and prevent further

decay.



**Why is dental amalgam a common material used in restorations?**

Dental amalgam is durable and cost-effective, making it suitable for restoring large cavities.

Amalgam offers long-lasting results, especially in areas of heavy chewing.



**Which dental instrument is used to carve anatomy into amalgam restorations?**

The burnisher is typically used to carve anatomy into amalgam.

The carver is used to shape the amalgam to mimic the tooth's natural contours.



**Why are composite resins preferred for anterior teeth restorations?**

Composite resins are highly aesthetic and can be matched to the tooth’s color.

Composite resins blend with natural teeth, offering an aesthetically pleasing restoration.



**What is a common step in preparing a tooth for a composite restoration?**

A desensitizer is applied to reduce post-restoration sensitivity.

, Etching is done to create a rough surface that allows the resin to bond more effectively.



**Which restorative material releases fluoride to help prevent future decay?**

Amalgam is known to release some protective ions.

Glass ionomer releases fluoride, which can help in preventing future caries.



**Why is moisture control important during restorative procedures?**

It helps keep the patient's mouth dry for comfort.

Moisture control is essential to ensure proper adhesion and curing of restorative materials.



**What is the role of the dental assistant in applying a matrix band?**

The dental assistant ensures the patient is comfortable while the dentist applies the matrix band.

The dental assistant places and removes the matrix band during the procedure, ensuring

proper contouring of the restoration.



**What technique is used to cure composite resins?**

A curing light is used to activate the bonding agent.

A light-curing technique using a high-intensity light source is applied to harden the

composite material.



**When is a wedge placed during restorative procedures?**

A wedge is not necessary for all restorations.

, A wedge is placed when a matrix band is used to separate teeth and secure the band for

proper restoration contours.



**Why is dental isolation important when working with composite resins?**

It helps the assistant work more efficiently.

Isolation ensures that the working area remains dry, critical for effective bonding.



**What is the primary difference between direct and indirect restorations?**

Indirect restorations are completed chairside.

Direct restorations are placed immediately into the tooth cavity, while indirect restorations

are fabricated outside the mouth.



**What material is commonly used in indirect restorations?**

Silver amalgam is used for indirect restorations.

Materials like porcelain or gold are commonly used in indirect restorations, such as crowns

or inlays.



**How is a properly finished composite restoration polished?**

Using a toothbrush and toothpaste.

Finishing burs and polishing discs are used to achieve a smooth, glossy surface on the

composite material.



**What complication might arise if a dental restoration is not contoured properly?**
