OBJECTIVE: The purpose of the
study was to compare the pain-related behavior and the pain perception
associated with three anesthetic techniques in pulpotomies of primary
mandibular second molars: traditional inferior alveolar nerve block (IANB),
IANB with computer-controlled local anesthetic delivery (CCLAD), and
intraligamental anesthesia with CCLAD.
METHOD AND MATERIALS: The sample comprised
91 randomly selected healthy children aged 5 to 9 years, who were scheduled
for pulpotomy in the mandibular second molar. Patients were divided into
three groups according to the type of anesthesia received. Group A received
traditional IANB, group B received IANB with CCLAD, and group C received
intraligamental anesthesia with CCLAD. Pain-related behavior and pain
perception levels were assessed using the established behavior code and the
Wong-Baker FACES Pain Rating Scale respectively.
RESULTS: The mean of
pain-related behavior was significantly lower (P < .001) in the
intraligamental anesthesia with CCLAD group than in the other two groups. The
pain perception scores were significantly higher in the traditional IANB
group than in the IANB with CCLAD group, and the intraligamental anesthesia
with CCLAD group (P = .044 and P < .001 respectively). The mean ± SD of
the pain perception of IANB was 1.39 ± 0.200, IANB with CCLAD was 0.87 ±
0.133 and ILA with CCLAD was 0.13 ± 0.063.
anaesthesia with CCLAD was clearly associated with less pain than the IANB
with or without CCLAD.

OBJECTIVE: The technique of local anesthetic administration is an
important consideration in the behavior guidance of a pediatric patient. The
study hypothesized that there is no difference in the pain effectiveness in
the experimental subjects with the use of single tooth anesthesia and the
controls with the use of conventional technique (traditional inferior
alveolar nerve block [IANB]).The purpose of this study was to compare the
anesthesia effectiveness of traditional IANB; IANB using a
computer-controlled local anesthetic delivery system (CCLAD); and
intraligamental anesthesia (ILA) using CCLAD in pulpotomy of the primary mandibular
METHOD AND MATERIALS: Ninety-one healthy 5- to 9-year-old children underwent
pulpotomy of the mandibular second molars. They were randomly assigned into
Group A (traditional IANB), Group B (IANB using CCLAD), or Group C (ILA
injection using CCLAD). The effectiveness of anesthesia was measured during
different steps of pulpotomy using the sounds, eyes, and motor (SEM) scale.
The postoperative complications were recorded after 24 hours.
RESULTS: For all five pulpotomy steps, the anesthesia effectiveness
was similar among the three anesthesia techniques. Anesthesia effectiveness
was not significantly different (based on SEM scores) between the three
groups during clamp application, drilling of the tooth, entering the pulp,
pulp extirpation, and removal of the clamp (P = .635, P = .996, P = .630, P =
.945, and P = .101, respectively). There was no significant difference in
postoperative complications between the three groups.
CONCLUSION: The IANB anesthesia using CCLAD
and periodontal ligament anesthesia using CCLAD were as effective as
traditional IANB in anesthetizing the primary mandibular molars during
