What is commonly recognized as the most frequent cause of needle breakage during dental procedures?

The most frequent cause of needle breakage during dental procedures is often attributed to sudden patient movement. When a patient moves unexpectedly while a needle is inserted, it can create undue stress on the needle. This stress might lead to bending or fracturing, especially at the hub where it is most vulnerable. Proper technique requires steady hands and anticipation of patient movement to minimize this risk.

While high gauge needles, improper storage, and lack of lubrication can contribute to complications during dental procedures, they are not as directly connected to the mechanical failure resulting in needle breakage as the influence of a sudden movement. Sudden patient movement creates an immediate and unpredictable factor that can increase the likelihood of breakage, making it a key concern for practitioners while administering local anesthesia.
