The anesthetic efficiency of retromolar infiltrations with two local anesthetic solutions of the same concentration in lower third molar surgery

Cyanoacrylate tissue adhesive versus silk sutures for mandibular third molar surgery: a systematic review and meta-analysis

OBJECTIVE

Cyanoacrylate tissue adhesive has been presented as an alternative to sutures and several studies have compared them. The objective of this meta-analysis was to evaluate the effect of cyanoacrylate tissue adhesive on postoperative pain and swelling, following mandibular third molar surgery.

MATERIALS AND METHODS

Database search was conducted in MEDLINE/PubMed and Scopus, along with extensive search in the grey literature, including randomized and non-randomized clinical trials that applied cyanoacrylate adhesive for closing mandibular third molar surgical sites and compared it with silk sutures, assessing postoperative pain and swelling. The search ended on September 22, 2023.

RESULTS

Of 886 identified articles, six were included and meta-analyzed. Applying cyanoacrylate demonstrated a reduction in the overall postoperative pain (SMD = -0.57, 95% CI -1.00 to -0.15, p = 0.009). A similar outcome was noted when pain was evaluated on the first and last postoperative days, based on controlled clinical trials (SMD = -0.47, 95% CI -0.92 to -0.03, p = 0.04), and randomized trials (SMD = -0.97, 95% CI -1.31 to -0.62, p < 0.00001). Patients/sides received cyanoacrylate showed a decrease in postoperative swelling (SMD = -0.26, 95% CI -0.51 to -0.01, p = 0.04). Following the GRADE rating system, the quality of evidence on pain and swelling was judged as moderate and low, respectively.

CONCLUSIONS

The use of cyanoacrylate adhesive may offer benefit in reducing postoperative pain and swelling following mandibular third molar surgery. Nevertheless, this should be further investigated, considering the low number of included reports.

CLINICAL RELEVANCE

The current results could help clinicians who perform this procedure to manage postoperative pain and swelling more effectively.

Twin Mixed Local Anesthesia in Third Molar Surgery - Randomized Controlled Trial

PURPOSE

The aim of this study was to compare the clinical efficacy of injection of 2 long-acting amide local anesthetic agents - bupivacaine and ropivacaine with and without 4 mg dexamethasone in patients undergoing third molar extraction.

METHODS

A prospective randomized double blind controlled trial was conducted among 68 patients with impacted mandibular third molars. Group A and B were the control groups and received 1.8 mL of 0.5% bupivacaine hydrochloride and 0.75% ropivacaine hydrochloride, respectively. Group A1 and B1 were experimental groups and received modified twin mixes which were 1.8 mL of 0.5% bupivacaine hydrochloride + 1mL/4mg dexamethasone and 0.75% ropivacaine hydrochloride + 1 mL/4mg dexamethasone, respectively. Visual analog pain scale, mouth opening measurement and facial swelling were assessed at the time of injection and postoperative days 1, 3, and 7.

RESULTS

The mean visual analogue scale score for pain on local anesthesia injection was found to be less in both experimental groups- Group A1 (2.94) and B1 (2.41) as compared to control groups- Group A (3.59) and B (3.06). The durations of soft tissue anesthesia were higher as compared to their respective controls for both Group A1 and B1. Patients in both control groups A and B had an increased postoperative swelling, pain and trismus.

CONCLUSIONS

Intraoperative and postoperative comfort in both the experimental groups were higher than those for control groups, thereby establishing the clinical efficacy of both modified twin mixes for use in surgical extraction of mandibular third molars.
