The outer diameter of the needle is generally 0.2-0.4mm larger than the inner diameter,
such as the outer diameter of a 27G needle is about 0.6-0.8mm 3;
The tip is divided into two types: flat head (direct flushing) and blind head (side wall opening
for anti-penetration) 36;
Some models provide dark green/yellow color markings for easy specification identification 4;
The length selection needs to be based on the operating depth requirements, and 50mm or
more is suitable for the posterior teeth area
| Model | Inner Dia (mm) | Length (mm) | Specification | Applicable scenarios | Other |
| 18G | 1.2 | 50 | Blunt needle/side hole design | Large flow flushing | Largest flow rate, larger outer diameter2 |
| 21G | 0.8 | 23/50/70 | Flat head/blind head | Routine flushing and periodontal care | Compatible syringes 12 |
| 22G | 0.7 | 50/70 | Conical joint design | Medical filling, deep flushing | 6:100 Standard interface 27 |
| 23G | 0.6 | 23/50/70 | Thin wall needle tube | Routine root canal irrigation | High flow design 27 |
| 25G | 0.5 | 23/38/50 | Double-sided opening | Fine root canal irrigation | Ultra-fine needle 24 |
| 27G | 0.4 | 23/38/50 | Flat head/side hole blind head | Narrow root canal irrigation | Need to be used with the crown open 35 |
| 30G | <0.3 | 23 | Custom Needles | Special narrow root canal | Need to be customized 13 |
