About aspirating syringes
An aspirating syringe is a cartridge syringe that can aspirate, which means checking before the solution goes in that the needle is not inside a blood vessel. A review states that aspiration during injections decreases the risk of intravascular injection, while a slow injection reduces tissue distortion and the discomfort that goes with it. ISO 9997 covers cartridge syringes of the non-aspirating, aspirating and self-aspirating types. A narrative review calls the standard aspirating syringe still the most popular way to give local anaesthetic.
A dental injecting needle is a slender, hollow metal device with a sharp point intended to be attached to a syringe to inject local anaesthetics and other drugs, and the FDA puts it in Class I. The syringe it attaches to is a cartridge syringe, a metal body that takes a disposable, previously filled glass carpule, which the FDA puts in Class II with special controls. ISO 7885 gives dimensional and performance requirements for single-use sterile injection needles used in dental cartridge syringes, and also covers their packaging, labelling and colour coding.
Needles used in dentistry have particular characteristics based on the ANSI/ADA and ISO standards. A study describes 27 and 30 caliber needles as thin, fragile and flexible, with lumens small enough that aspiration can be harder. Disposable single-use needles have made needle fracture rare, though it remains a serious event.
How aspirating syringes, short needles and long needles differ
- Aspirating Syringes — The instrument that holds the cartridge, in a version that can aspirate rather than one that cannot. Safety versions carry a sheath that locks over the tip of the needle after the injection, and a narrative review notes the Centers for Disease Control and Prevention has recommended safe dental syringes.
- Short Needles — The shorter of the two lengths kept here, approximately 20 mm within a range of 20 to 25 mm. A study found that the more deeply a needle penetrates, the greater the probability of permanent deformation and fracturing.
- Long Needles — The longer of the two lengths kept here, approximately 32 mm within a range of 30 to 35 mm. A study notes that touching bone during an injection can bend the needle, and that in theory a needle takes that deflection without fracturing.
What to look at when choosing needles and syringes
Gauge: a study of used needles found bevel deformation in 93 of 192 needles, with 30-gauge needles showing higher odds of deformation than 27-gauge ones and each additional insertion raising the odds further. The same study notes that 30-gauge needles are often preferred to reduce pain on insertion but are susceptible to deflection and fracture compared with 27-gauge.
Single use: that study found deformation even where no bone contact was intended, which it reads as support for strict single-use practice and careful handling.
Labelling: the same study recorded products where the manufacturer did not indicate the information on the packaging.
Scope of the standard: ISO 7885 does not cover needles for special applications or techniques, and only the materials used for the needle tubing are specified in it.
