Evaluation of low-level laser at auriculotherapy points to reduce postoperative pain in inferior third molar surgery: study protocol for a randomized controlled trial.

ABSTRACT:

Background

A comfortable postoperative return to daily activities has increased the need to control inflammation after third molar surgery. Anti-inflammatory drugs and analgesics are not exempt from adverse effects such as allergies and chronic gastritis, and they are not without cost. The association between low-level laser and auricular acupuncture can be an alternative when conventional drugs are contraindicated. Among its advantages, we can mention the low risk of side effects, low cost and simplicity of application. The objective of this study is to evaluate the efficiency of low-level laser at auriculotherapy points in reducing postoperative pain in lower third molar surgery.

Methods/design

Ninety bilateral, symmetrical lower third molar surgeries will be performed in 45 healthy patients. Each patient will be their own control, through a split-mouth crossover study. One side of the mouth will be randomly chosen and, immediately after surgery, will be treated with low-level laser. After 21 days, the contralateral side will be operated on with low-level laser simulation used postoperatively. This regimen (laser application or not) will be repeated at 24 and 48 h after surgery. All patients will be requested to take analgesics (acetaminophen) if they have pain, i.e. in case of pain. Neither the surgeon nor the patients will know the assigned treatment. The primary variable will be postoperative pain assessed using a Visual Analog Scale, and the secondary variables will be trismus, edema, local temperature, dysphagia, presence of infection and painkiller ingestion. These variables will be assessed at baseline, 24 h, 48 h and 7 days after surgery. Blood samples for systemic inflammatory cytokine (TNF-?, IL-1, IL-6 and IL-8) analysis will be assessed at baseline and 24 h after surgery.

Discussion

Some authors believe that using a wavelength of 633 to 670 nm is a good option for laser therapy in the field of acupuncture. This wavelength can penetrate biological tissue to a depth of about 3 mm. However, for auriculotherapy points, the stimulus (mustard seeds, needles 1 to 2.5 mm) does not penetrate so deeply. For this reason, we chose a laser wavelength of 660 nm (red wavelength).

Project description:BackgroundSurgical extraction of the impacted mandibular third molar is commonly associated with postoperative pain, swelling, and trismus. Usually, rotatory instruments like burs have been used for osteotomy, while Piezosurgery is an innovative technique introduced to overcome the weaknesses related to the conventional technique. In addition, Dexamethasone administration before the extraction of impacted third molars is an efficient way to reduce postoperative pain due to robust anti-inflammatory activity. The purpose of the study is to evaluate the effect of piezo-surgery and dexamethasone injection on postoperative sequelae after the surgical extraction of impacted mandibular third molars, and ultimately to compare their effect on reducing postoperative pain.MethodsA randomized controlled clinical trial was conducted with a sample of 80 patients. Participants were divided into four groups: Group 1 (Conventional rotatory), Group 2 (Conventional rotatory with 8 mg dose of dexamethasone 30 min before surgery), Group 3 (Piezo-surgery), and Group 4 (Piezo-surgery with 8 mg dose of dexamethasone 30 min before surgery). The outcome variables were surgical working time calculated in minutes, maximal mouth opening measured in millimeters using Vernier Caliper at baseline and day 3 and postoperative pain assessed using a Visual Analog Scale (VAS) on days 1, 3, and 7.ResultsThe surgical working time was longer in piezo-surgery groups compared with the conventional rotatory instruments groups (15.82 ± 3.47 vs 23.33 ± 2.54; p value < 0.0001). The lowest reduction in mouth opening between baseline and 3rd-day post-op was found in the Piezo-surgery with Dexamethasone group (mean difference = 5.0, SD = 3.9, p value < 0.0001) followed by the Piezosurgery without Dexamethasone group (mean difference = 5.8, SD = 4.5, p value < 0.0001) and the highest average was reported by the Conventional rotatory without Dexamethasone (mean difference = 9.7, SD = 4.5, p value < 0.0001. In the four groups, the mean pain score was highest on the 1st day and gradually decreased over the following days. Comparison of the 1st and 3rd postoperative pain between groups revealed a lowest mean pain score in the Piezo-surgery with Dexamethasone group, followed by Conventional rotatory with Dexamethasone group and a highest mean score in the Conventional rotatory without Dexamethasone group (p value < 0.0001).ConclusionThe association of Piezosurgery osteotomy and Dexamethasone intramuscular injection could be an effective combination to reduce postoperative pain and trismus after impacted third molar surgery.Trial registrationNCT04889781 ( https://clinicaltrials.gov/ ), Date of Registration: 17/05/2021 (retrospectively registered), https://clinicaltrials.gov/ct2/show/NCT04889781?term=NCT04889781&draw=2&rank=1.

Project description:BackgroundUnderstanding how adolescent patients make decisions about pain management after complex dental procedures could help reduce the use of opioid medications and the potential for future opioid misuse in this population. This qualitative study explores how adolescents manage pain, including how decision making with parents and providers affect their experience with opioid and non-opioid analgesics after third molar dental extractions.MethodsWe used a qualitative approach for the analysis of 30 telephone-based semi-structured interviews completed by 15 dyads between May and August 2019, which included 15 adolescents (15-17 years) who underwent a dental extraction, and a parent or guardian for each adolescent. The total sample included 30 participants. Interviews were conducted separately for patients and parents. De-identified interview transcripts were analyzed using qualitative analysis software using a directed content analysis approach.ResultsA total of 15 patient/parent dyads were interviewed. Key themes associated with pain management included sources of information, pain management behaviors engaged in by the adolescents and their caregivers, and the use of medication. In addition to conversations with their dental provider, most patients and their parents discussed pain management plans that included non-medication options, over-the-counter medications, and opioid medications to be taken as needed, which guided their post-extraction behaviors. All participants reported that the adolescent received an opioid prescription for post-extraction pain management, to be taken on an "as needed" basis, but most only took it the day of the extraction and up to 2 days following, usually based on the patient's reported pain levels and perceptions of over-the-counter medication adequacy. Participants said they did not receive guidance from their provider concerning disposal of unused opioid medications.ConclusionsInvolving adolescents in the pain management decision making process and allowing them to carry out the plan with some caregiver support was acceptable and well executed following third molar extractions. Providers may have an opportunity to reduce the number of opioids prescribed, since respondents reported little to no use of opioids that they were prescribed. Providers should educate patients and their parents about safe disposal of opioids to mitigate the potential for diversion.
