Intrapapillary injection technique for children

This provides suitable palatal analgesia for rubber dam, matrix band or stainless steel crown placement on all maxillary primary teeth. It will also give adequate analgesia for extraction of primary incisors and canines. It will produce the same effect in the lower arch in children of 5 years of age and below where infiltration rather than block analgesia has been administered.

Figure 1 : A buccal infiltration injection is administered. After approximately two minutes, analgesia of the buccal aspect of the interdental papillae mesial and distal to the tooth is tested with a probe.

Figure 2 ;The interdental papilla is penetrated using a 30-gauge needle to a depth of 1–2 mm. The syringe barrel is held parallel to the occlusal plane and perpendicular to the line of the arch. Local analgesic solution is injected slowly, and the needle is gently advanced to a depth of a few millimetres.

Figure 3 :  Injection should continue until blanching of the palate is observed extending more than halfway along the palatal gingival margin. This usually takes 20–30 seconds.

Figure 4 :  The same procedure is repeated on the other side of the tooth, with injection continuing until the blanching extends to and joins with that produced by the previous injection. Analgesia of the complete gingival cuff has now been achieved.
