**Question:** Final finishing of composite resin is usually done

**Core Concept:** The process of polishing composite resin after its placement is essential for achieving a smooth, esthetic, and functional restoration. This includes removing excess material, achieving proper contours, and enhancing the surface gloss and durability.

**Why the Correct Answer is Right:**
The correct answer, **Option C: Polishing discs**, is chosen for the final finishing of composite resin because:
1. Polishing discs are specifically designed to remove excess material, smoothen the surface, and refine the contours of the composite restoration.
2. They provide a controlled and consistent polishing action, ensuring a high-quality restoration with minimal risk of causing damage to the surrounding tissues or other adjacent teeth.
3. Polishing discs allow for proper surface preparation, enhancing the surface gloss and durability of the composite resin, which is crucial for long-term success of the restoration.

**Why Each Wrong Option is Incorrect:**

A. **Option A: Abrasive points** are not suitable for final finishing as they are too coarse and can cause damage to the restoration and surrounding tissues.
B. **Option D: Abrasive burs** are also too coarse and may cause damage to the restoration and surrounding tissues, making them unsuitable for final finishing.
C. **Option C: Polishing discs** are chosen, as explained above, for their controlled polishing action, minimizing damage and ensuring a high-quality restoration.

**Clinical Pearl:**

Achieving a properly finished and polished composite resin restoration is essential for patient satisfaction, restoration longevity, and overall oral health. Proper technique and choice of materials, like polishing discs, can significantly impact the success of the restoration. Always ensure to remove excess material, refine contours, and enhance surface gloss and durability using appropriate polishing techniques and tools.
