AIM: The purpose of this study was to evaluate clinically and radiographically
pulpotomies carried out under intrapulpal injection of anaesthetic solution.
METHODOLOGY: Forty-one permanent mandibular molar teeth presenting with deep
carious lesions and/or exposed pulps, with or without periapical changes on
radiographic examination, were treated with pulpotomy and dressed with calcium
hydroxide. The teeth were divided into three groups. Group A consisted of 15
teeth, where intrapulpal anaesthesia was administered by a slow injection of
lidocaine hydrochloride 2%. Group B, with 14 teeth, where intrapulpal anaesthesia
was obtained with lidocaine hydrochloride 2% with adrenaline 1:100,000. Group C
consisted of 12 teeth in which anaesthesia was performed with a mandibular block
using prilocaine hydrochloride 3% with felypressin 1: 100,000. Healing was
evaluated using clinical and radiographic criteria: dentine barrier formation,
absence of clinical symptoms and resolution of periapical involvement.
RESULTS: After an observation time of 6-8 weeks (postoperative control) and 24-32
weeks (intermediate control), healing occurred in 13 teeth from group A (87%), in
11 teeth from group B (79%) and in 10 teeth from group C (83%). No statistical
difference was demonstrated between the three groups (Fisher's exact test).
CONCLUSIONS: Based on the methodology adopted, intrapulpal injection of
anaesthetic solution did not impair healing in pulpotomized teeth.
