What is Trifurcation in dentistry?

1. Division of two teeth at the crown

2. Connection between teeth roots

3. Division of three tooth roots at their point of junction with the root trunk

4. Formation of tooth decay

The correct answer is: Division of three tooth roots at their point of junction with the root trunk

Trifurcation in dentistry refers specifically to the division of three tooth roots at their point of junction with the root trunk. This anatomical feature is significant in certain teeth, especially in molars, where there can be three distinct roots that support the overall structure and function of the tooth in the jaw. Understanding trifurcation is essential for procedures such as root canal treatments or extractions, where the condition and connectivity of these roots play a crucial role in treatment planning and execution. Recognizing where trifurcation occurs helps dental professionals manage the complexities associated with such multi-rooted teeth effectively, ensuring proper care and treatment outcomes.
