MARTINEZ-MARTINEZ, Adel; JIMENEZ-BATISTA, Elio y MORALES-JIMENEZ, Alexander. Use of bufferized dental anesthetics in dental surgery. CES odontol. [online]. 2021, vol.34, n.1, pp.35-43. Epub 16-Feb-2022. ISSN 0120-971X. https://doi.org/10.21615/cesodon.34.1.4.
Introduction and objective:
The addition of epinephrine to the anesthetic solution reduces the pH of the solution to a range between 2.9 and 4.4. The acidity of the anesthetic may delay onset and contribute to injection pain.
Objective:
to determine the intensity of pain during a mandibular third molar surgery after using buffered 4% articaine with epinephrine 1:100000 in the inferior alveolar nerve block with buccal infiltration.
Materials and methods:
an observational and descriptive clinical study was performed. The buffered solution was alkalinized with 8.4% sodium bicarbonate with a ratio of 9:1, using a hand-mixing methodology, the sample were patients who required a mandibular third molar surgery. After standardizing the anesthetic technique, it was used the inferior alveolar nerve block followed by buccal infiltration.
Results:
32 patients (20 female - 62.5% and 12 male - 37.5%), with an average age of 21.12 years (mean ± standard deviation : 21.12 ± 3.61) were admitted to the study. When assessing the pain puncture and during the injection, 94% of patients classified it as mild pain according to VAS. When evaluating the latency period, the average time was less than two minutes and the perioral soft tissue anesthesia was 62%. Only a small percentage of patients required complementary anes thesia.
Conclusion:
buffered 4% of articaine with epinephrine in the in ferior alveolar nerve block with buccal infiltration significantly decreased onset time, injection pain and need for complementary anesthesia in third molar surgery.
