Researchers are analyzing whether the bur debris dental drills leave behind pose health risks to patients. Although dentists use dental drills to prepare teeth for fillings, researchers know little about their potential health risks.
Researchers have analyzed imaging analyses which show dental bur fragments of different sizes in different locations. The fragments are located on the tooth's prepared surface floor and under the filling, placing the fragments in direct contact with tubules and fluid within dentin.
"Further studies need to investigate if or to what extent the small amount of bio-incompatible debris constitutes a biohazard to patients," researchers concluded.
