TY - JOUR ID - TI - Single Buccal Injection for Anesthesia of Upper First Molar AU - Mohamed S. Suleiman AU - Wafaa K. Fathi AU - Rayan S. Hamid PY - 2008 VL - 8 IS - 1 SP - 56 EP - 60 JO - Al-Rafidain Dental Journal مجلة الرافدين لطب الأسنان SN - 18121217 19980345 AB - Aims: A clinical trial was carried out to assess the efficiency of a single buccal injection to achieve
anesthesia of the buccal aspect of the upper first molar instead of the traditional two injections. Materials
and Methods: The subjects included in the clinical assessment were those needing extraction of
an upper first molar of either side. For the purpose of comparison, the sample was randomly divided
into two main groups: Group I (control group) which included 100 subjects who were to receive two
buccal injections and a single palatal injection before extraction. While Group II (trial group) included
100 subjects who were to receive a single buccal injection and a single palatal injection before extraction.
The following data were recorded: Pain on needle insertion, pain on deposition of solution, onset
of surgical anesthesia and adequate surgical anesthesia. Results: The first criterion recorded was pain
on needle insertion where the results showed no significant difference between both groups. The
second criterion was pain on deposition of solution. Here the results also showed no significant difference
between both groups in this aspect. For onset of surgical anesthesia, no significant difference was
shown between both groups. In regard to pain grade experienced during surgery for both groups, the
results showed that grade A anesthesia was recorded in 95% of patients in group I , whereas in 93% of
patients in group II. Grade B anesthesia was recorded in 5% of patients in group I and in 7% of patients
in group II. Statistically speaking, no significant difference was disclosed in regard to pain assessed
during the extraction of the tooth between both groups. Conclusions: The achievement of successful
local anesthesia is a continual challenge in dentistry. Any suggested new approach for achieving adequate
anesthesia for either the maxilla or mandible as long as it is safe and effective can be recommended
for routine dental care.
