RESUMO
The extraction of wisdom teeth with mandibular impact frequently results in complications including damage to the inferior alveolar nerve (IAN) and malformations of the bone. The objective of this research endeavour was to assess the efficacy of low-level laser therapy and concentrated growth factor (CGF) in facilitating nerve recovery and wound healing in such instances. A total of thirty-one patients (mean age 27.52 ± 5.79 years) who presented with IAN injury after extraction were randomly assigned to one of three groups: control group (which received oral mecobalamin), CGF group (which received CGF gel applied to the extraction sockets) and laser group (which received low-level lasers (808 nm, 30 mW, 10 J/cm2 )) at the extraction site. Patients' recovery from IAN paresthesia was evaluated seven times over the course of 14 days utilizing visual analogue scale (VAS) and the pinprick test (PP). At multiple intervals following surgery, periodontal probing and bone level measurements were utilized to assess the recovery of both soft and hard tissues. The findings revealed that, compared with the control group, both the CGF and laser treatment groups exhibited a markedly greater improvement in VAS scores and wound healing of soft tissues, as well as in PP results (p < 0.001), indicating enhanced wound healing processes. Despite these improvements, there was no significant difference in wound healing outcomes between the CGF and laser groups. Notably, the CGF group showed a statistically significant improvement in healing bone defects at 30 and 90 days post-treatment compared with the control group (p = 0.003 and p = 0.004, respectively), underscoring its effectiveness in bone healing as a critical aspect of the overall wound healing process. However, in terms of other wound healing comparisons, no significant differences were observed. CGF and laser therapy significantly enhanced the healing of wounds, including soft tissue and bone recovery, in addition to accelerating the recovery of IAN injuries following mandibular wisdom tooth extraction. Although both treatments were equally effective in nerve recovery, CGF notably excelled in promoting bone healing, suggesting its pivotal role in comprehensive wound healing. This highlights that both CGF and laser therapy are viable options for not only nerve recovery but also for overall wound healing in such dental procedures.

BACKGROUND: The aim of this split-mouth, randomized, placebo-controlled, and triple-blind study was to evaluate whether auriculotherapy had any effect on the post-operative course after the extraction of third molars in terms of the control of pain, edema, and trismus. MATERIALS AND METHODS: The study included 42 patients (84 teeth) who had undergone a surgical extraction of the lower third molars. In each patient, the two extractions were randomly assigned to two study groups. In the therapy group, the patients underwent auriculotherapy with vaccaria seeds applied with patches in 6 ear points. In the control group, the patches were applied, without seeds, to the same ear points. After the extraction, the patients were asked to stimulate the ear points three times a day and whenever they felt pain. The patients were asked to keep a diary in which they assessed their pain by means of the Visual Analog Scale (VAS) for 8 days. Edema and trismus were assessed 1, 2, 3, and 8 days after surgery. RESULTS: The differences between the two groups were statistically significant at the 12-h control (auriculotherapy group (AG) VAS 5.5 [IQR 4.25-6.75], placebo group (PG) VAS 6 [IQR 5-8], p = 0.040), after 24 h (AG VAS 5 [IQR 4-6], PG VAS 6 [IQR 4.25-7], p = 0.024), after 2 days (AG VAS 4 [IQR 3-5], PG VAS 4.5 [IQR 4-6], p = 0.044), and after 3 days (AG VAS 3 [IQR 0-5], PG VAS 4 [IQR 3-5], p = 0.024). Throughout the observation period, the AG took a significantly lower number of painkillers than the PG (AG 6 [IQR 4.25-7]; PG 8 [IQR 8-9], p < 0.001). There were no significant differences in the levels of edema and trismus between the two groups throughout the observation period. CONCLUSIONS: On the basis of the results of the present study, auriculotherapy can be considered as a cost-effective adjuvant pain reliever treatment in patients undergoing an extraction of the lower third molars.

BACKGROUND: The transcutaneous electrical nerve stimulation (TENS) stimulus inhibits the activity of nociceptive neurons of the central nervous system. Pain relief is achieved by increasing the pulse amplitude of TENS to induce a non-painful paranesthesia beneath the electrodes. This study aimed to assess the effect of TENS on acute pain, edema, and trismus after surgical removal of impacted third molars. MATERIAL AND METHODS: This randomized, double blind, split-mouth clinical trial was conducted on 37 patients with bilaterally impacted mandibular third molars. The angle and body of mandible at the site of surgery in one randomly selected quadrant underwent TENS immediately after surgery (50 Hz, 100-µs short pulse, 15 minutes for 6 days). The TENS stimulator device was used in off mode for the placebo quadrant. The pain score (primary outcome) was measured for 7 days postoperatively, and edema and trismus (secondary outcomes) were assessed at 2, 4 and 7 days, postoperatively. The results were analyzed by repeated measures ANOVA using R software (alpha=0.05). RESULTS: The overall mean pain score was significantly lower in the TENS than the placebo group (P<0.05). The number of taken analgesics in the first 3 days was significantly lower in the TENS group (P<0.001). Postoperative edema in the TENS group was lower than the placebo group but only the difference was not statistically significant (P>.05). The inter-incisal distance, as an index to assess trismus, was not significantly different between the two group at day 2, but it was significantly higher in the TENS group after the second day (P<0.001). CONCLUSIONS: TENS effectively decreased pain and trismus following impacted third molar surgery, and may be recommended as a non-pharmaceutical method to relieve postoperative symptoms.

BACKGROUND: Postoperative supplemental maintenance following mandibular third molar surgery remains an area of interest. PURPOSE: Topical agents can modulate inflammatory processes. The aim of the present study was to determine if topical application of arnica or mucopolysaccharide polysulfate (MPSP) reduces pain, trismus, and edema following the removal of impacted mandibular third molars. MATERIALS AND METHODS: A single center randomized controlled clinical trial was conducted. The patients were randomized into three groups: the control group (standard therapy [ST]: antibiotic + nonsteroidal anti-inflammatory drugs twice a day), the arnica group (arnica + ST), and the MPSP group (MPSP + ST). The patients' pain, trismus, and edema values were measured preoperatively and on postoperative days 1, 3, 5, and 10. Sex, age, and operation time were also included. Analyses included descriptive statistics, analysis of variance, post hoc tests, and determinations of intraclass correlation coefficients. Statistical significance was set at P < .05. RESULTS: Sixty patients with a mean age of 26.98 ± 10.88 years were included in the study; 55% were females and 45% were males. The mean operation time was 23.8 ± 3.27 minutes. According to the visual analogue scale scores (in centimeter units), the arnica and MPSP groups felt less pain than the control group until day 5 (0.6 ± 0.88, 3.75 ± 1.16, 4.75 ± 1.29, and 1.05 ± 1.10, respectively, for the arnica group; 0.35 ± 0.59, 3.25 ± 1.62, 5.0 ± 1.65, and 1.50 ± 1.32 for the MPSP group; and 1.30 ± 1.17, 5.75 ± 1.37, 7.05 ± 1.10, and 3.15 ± 1.53 for the control group; P < .05). The trismus was lower on days 1, 3, and 5 in the arnica group (-8.05 ± 2.82, -12.15 ± 3.1, and -2.15 ± 1.81, respectively) than in the control group (-12 ± 3.82, -15.65 ± 4.81, and -4±2.81, respectively) (P < .05). The edema was lower on days 1 and 3 in the MPSP group (0.95 ± 2.2 and 1.75 ± 3.7, respectively) than in the control group (2.45 ± 0.9 and 3.6 ± 0.8, respectively) (P < .05). Arnica and MPSP had similar pain-relieving action, but arnica was more effective at reducing trismus, while MPSP was more effective at reducing edema. CONCLUSIONS: Topical application of arnica or MPSP may have a beneficial effect on relieving pain 5 days after surgery, but arnica was also effective at reducing trismus, while MPSP was also effective at reducing edema. Both arnica and MPSP reduced postoperative sequelae.

The objective of this research was to evaluate the effectiveness of using LPL (Low power laser) to reduce pain, edema, and trismus after impacted lower third molar extraction. A split-mouth randomized triple-blind clinical trial was conducted at the Federal University of Ceará. For inclusion criteria, it was necessary that the patient presented a clear indication for removal of both lower third molars, in addition to both molars being in similar positions. The third molars (38 and 48) were randomly allocated to the test group that received the LPL application protocol, and to the placebo group that received a simulation of the protocol, making a total sample of 44 surgeries. Patients in the test group used an average of 50% of the amount of analgesics that was used by the placebo group, however, there was a statistically significant difference only on days four and five. Regarding trismus, the test group presented wide mouth openings, both at 48 hours and at 7 days after surgery compared to the placebo group, but without a statistically significant difference. For edema, we noted an equilibrium between the test group and the placebo group, but no measurement obtained a statistically significant difference. The use of LPL presented better pain and trismus indicators after complex extractions. The use of LPL is thus indicated as a complementary therapy to reduce postoperative discomfort caused by complex tooth extractions.

BACKGROUND: Pain is the most prevalent complication after dentoalveolar surgery. Failure in effective pain control could potentially lead to systemic sequels, such as tachycardia, hypertension, improper nutrition, and central sensitization. Pregabalin is a gamma-aminobutyric acid (GABA) analog with inhibitory and analgesic effects on the central nervous system (CNS). Prescribing gabapentinoids as complementary analgesics reduces the consumption of opioid and non-opioid analgesics, and consequently their side effects. OBJECTIVES: The main purpose of the present study was to compare the analgesic effects of pregabalin (single-dose 75 mg) vs. ibuprofen (single-dose 400 mg) on patients' pain levels after impacted third mandibular molar surgery. MATERIAL AND METHODS: In this randomized, double-blind, split-mouth clinical trial, 24 patients aged 19-34 years volunteered for 2 consecutive (1 month apart) third mandibular molar surgeries (the contralateral teeth). The patients were randomly placed into 2 groups: group G1 (n = 12) was prescribed pregabalin (single-dose 75 mg) after the 1st surgery and ibuprofen (single-dose 400 mg) after the 2nd surgery; and group G2 (n = 12) was prescribed the exact opposite of the G1 arrangement. During the first 24 h post-surgery, the patients recorded the number of complementary analgesics they took (single-dose 400 mg ibuprofen) and their level of pain on a visual analog scale (VAS) every 2 h. RESULTS: The average level of pain at 2 h post-surgery (T1) was significantly lower when pregabalin was prescribed (p < 0.05). Most patients needed complementary analgesics at 4 h post-surgery (T2). However, during the first 24 h post-surgery, the patients required significantly more complementary analgesics when ibuprofen was prescribed. CONCLUSIONS: In comparison with oral ibuprofen (single-dose 400 mg), oral pregabalin (single-dose 75 mg) had a stronger analgesic effect at 2 h after impacted third mandibular molar surgery (p < 0.05). Pregabalin resulted in a significantly lower consumption of complementary analgesics in the first 24 h post-surgery as compared to ibuprofen.

Context: Impacted maxillary central incisors (MCIs) can seriously affect children's appearance, verbal abilities, and maxillofacial development. Clinically, a combination of surgically assisted eruption and orthodontic traction is the treatment modality most acceptable to dentists and children's families. However, previously used traction methods have been complex and required a long treatment time. Objective: The study intended to evaluate the clinical effects of the use of the research team's adjustable removable traction appliance combined with a surgically assisted eruption of impacted MCIs. Design: The research team performed a controlled prospective study. Setting: The study took place at Department of Orthodontics, Hefei Stomatological, Hospital. Participants: 10 patients with impacted MCIs, aged 7-10 years, who had visited the hospital between September 2017 and December 2018. Intervention: The research team assigned the impacted MCIs to the intervent ion group and contral ateral normal MCIs to thecontrol group. For the intervention group, the research team performed a surgical eruption and inserted the adjustable removable traction appliance. The control group received no treatments. Outcome Measures: Postintervention, the research team determined the mobility of both groups' teeth. At baseline and immediately postintervention for both groups, the team performed cone-beam computed tomography (CBCT) and measured root length, apical-foramen width, volume, surface area, and root-canal wall thickness for the labial and palatal sides. For both groups, after the intervention group's treatments, the team: (1) performed electric pulp testing and periodontal probing on the participants' teeth; (2) measured and documented pulp vitality, gingival index, periodontal probing depth, and gingival height (GH)for the labial and palatal sides; and (3) measured labial-and-palatal, alveolar bone level and alveolar bone thickness. Results: At baseline, the intervention group showed delayed root development, and that group's root length was significantly shorter (P < .05) and apical-foramen width (P < .05) was significantly greater than those of the control group. The intervention group's treatment success rate was 100%. And the intervention group did not have any adverse reactions, such as tooth loosening, gingival redness and swelling, or bleeding. Postintervention, the intervention group's labial GH was significantly higher than that of the control group, at 10.58 ± 0.45 mm and 9.47 ± 0.31 mm, respectively (P = .000). The increase in the intervention group's root length postintervention was significantly greater than that of the control group, at 2.80 ± 1.09 mm and 1.84 ± 0.97 mm, respectively (P < .05). The intervention group also had significantly greater decrease in the apical-foramen width than the control group did, at 1.79 ± 0.59 mm and 0.96 ± 0.40 mm, respectively (P < .05). At the end of traction, the intervention group had significantly higher labial-and-palatal alveolar-bone levels, at 1.77 ± 0.37 mm and 1.23 ± 0.21 mm, respectively, than the control group did, at 1.25 ± 0.26 mm (P = .002) and 1.05 ± 0.15 mm (P = .036), respectively. The labial alveolar-bone thickness in the intervention group was thinner than that of the control group, at 1.49 ± 0.31 mm and 1.80 ± 0.11 mm, respectively (P = .008). The volume and surface area (P < .01) of the intervention group's impacted teeth had increased significantly postintervention (both P < .01), but both were significantly smaller than those of the control group, both at baseline and postintervention. Conclusions: An adjustable removable traction appliance combined with a surgically assisted eruption can be a reliable treatment for impacted MCIs and can provide root development and a good periodontal-pulp condition postintervention.

PURPOSE: To evaluate time-dependent administration of ibuprofen in a lower third molar extraction model. METHODS: Eleven patients requiring bilateral surgical removal of lower third molars were recruited and randomized into a blinded crossover randomized controlled trial. For 3 days after surgery, the control group was prescribed ibuprofen 400 mg every 8 h. On the other hand, the experimental group received also ibuprofen 400 mg at breakfast and lunch, replacing the dinner intake with a placebo. Pain measurements (Visual Analog Scale from 0 to 10) were recorded at baseline, 24, 48, and 72 h postoperatively. Facial swelling and trismus were also measured at baseline, 24, and 72 h postoperatively. RESULTS: Postoperative swelling and pain perception did not show significative difference between the control and experimental groups at 24, 48, and 72 h. Trismus was significantly lower in the control group than in the experimental group at 72 h postoperatively (p = 0.008). Rescue medication consumption seemed to be comparable between groups. CONCLUSION: Eliminating night time ibuprofen might be insignificant for pain control after third molar extraction.

BACKGROUND: Abstraction of wisdom teeth or impacted third molar under local anaesthesia is one of the most frequent interventions by an oral and maxillofacial surgeon. The abstraction of the third molar is usually followed by the release of liberation and consequent trismus, pain, and swelling due to the area of the third molar being highly vascularized and rich in loose connective tissue. Objective of the study was to evaluate the anti-inflammatory effect of ascorbic acid following surgical extraction of the third molar. METHODS: The current study was carried out Armed Forces Institute of Dentistry, Rawalpindi, from October to December 2022. This was a cross-sectional observational study. Fifty participants who required surgical extraction of the impacted third molar were included in the study via non-probability purposive sampling and were segregated equally into two groups, i.e., Group A and Group B, comprising twenty-five participants in each group. Group A received amoxicillin with clavulanic acid (625 mg) thrice a day and metronidazole (400 mg) twice daily. In comparison, Group B received amoxicillin with clavulanic acid (625 mg) thrice daily, ascorbic acid (500 mg) twice daily, and metronidazole (400 mg) twice daily. Both groups received naproxen sodium as per requirement (550 mg). Pain, facial swelling, and C reactive protein concentration were evaluated until the 7th postoperative day. RESULTS: There was a reduction in pain and facial swelling in both groups, but in the ascorbic acid group, there was more reduction in pain and facial swelling compared to the control group. However, the difference between the two groups in reducing pain and facial swelling was statistically significant (p<0.01). There was a reduction in CRP in both groups, but in the ascorbic acid group, there was more reduction in CRP 2.35 (1.60-5.30) compared to the control group 2.6 (0.86-5.03). However, the difference between the two groups in reducing C reactive protein concentration was statistically insignificant (p>0.05). CONCLUSIONS: Our study concluded that ascorbic acid significantly reduced inflammation and C reactive protein, so ascorbic acid should be used as an adjuvant supplement with other conventional drugs.

BACKGROUND: This study aimed to assess the effect of extraoral 940 nm low-level diode laser on pain, edema, and trismus following surgical extraction of impacted mandibular third molars. MATERIALS AND METHODS: This split-mouth, randomized, placebo-controlled clinical trial evaluated 25 patients with bilaterally impacted mandibular third molars. One side of the jaw was randomly assigned to the laser and the other side to the control group. The laser quadrant received 940 nm diode laser irradiation (0.5 W, 10 J/cm2, continuous-wave mode, 20 s) at three points in the master muscle in contact mode immediately after surgical extraction of third molar. The third molar in the placebo quadrant was extracted after 2 weeks by the same surgeon using the same standard approach. The pain score was measured at 2 and 7 days postoperatively using a visual analog scale (VAS). To assess trismus, the distance between the incisal edges of the upper and lower central incisors was measured in maximum opening. To assess edema, the distance between the tragus and chin point was measured before and immediately after surgery and after 2 and 7 days. Data were analyzed using t-test, ANOVA, and Bonferroni test. RESULTS: The mean pain score in the first 7 days was significantly lower in the laser group (P < 0.05). Edema and trismus were the same in both groups (P > 0.05). Number of analgesics taken was significantly lower in the laser group (P < 0.05). CONCLUSION: Single-session irradiation of 940 nm diode laser can effectively decrease pain following third molar extraction surgery. TRIAL REGISTRATION NUMBER: IRCT20141209020258N91 on 29/12/2018.

OBJECTIVE: The aim of this study is to compare the effect of photobiomodulation with low-level laser therapy (LLLT) and nimesulide on inflammatory parameters, biomarkers of oxidative stress and inflammation, and quality of life after lower third molar (L3M) surgery. MATERIAL AND METHODS: A randomized, two-factor, triple-blind, controlled, split-mouth clinical trial was performed with 40 volunteers who required bilateral L3M removal. Patients were allocated depending on the use or not of 100 mg nimesulide 1 hbefore surgery, as well as the use or not of LLLT in the preoperative period. RESULTS: Pain peaks occurred after 6 h (nimesulide-placebo [N-P] group) and 8 h (nimesulide group). In the N-P group, LLLT resulted in significantly lower mean pain scores than the subgroup without LLLT after 4 h (p = 0.009) and 6 h (p = 0.048). As for edema, a shorter distance between the mandibular angle and the outer canthus of the eyes after 7 days (p = 0.037) and a smaller cumulative effect (p = 0.036) were observed in the N-P group associated with LLLT. A direct effect between LLLT (p = 0.047) and a reduction in the mean scores of overall dissatisfaction with quality of life was detected. CONCLUSIONS: Preemptive use of nimesulide only delayed peak pain. LLLT reduced edema, trismus, and contributed to a better perception of quality of life. Nimesulide inhibits peroxidation by increasing GSH and stopping neutrophil migration. The benefit of the association of both strategies was not superior to the use of LLLT alone. CLINICAL RELEVANCE: Translational study with impact on clinical-surgical protocols involving L3M surgery related to pharmacological and non-pharmacological methods.

OBJECTIVES: To evaluate the effect of kinesiology tape application after mandibular third molar extraction. METHOD AND MATERIALS: Patients with mandibular third molar extraction indications were divided into three groups. The patients in group 1 had kinesiology tape applied after tooth extraction, the patients in group 2 were given an ice pack and intermittent cryotherapy within 24 h of the operation, and the patients in group 3 were not given any additional intervention. All patients were followed up, and the postoperative swelling, pain, mouth opening limitation, and quality of life were recorded and evaluated. Comments on the intervention methods from patients were also collected. RESULTS: Compared to group 3, groups 1 and 2 showed a significant reduction in postoperative swelling, pain, and limitation of mouth opening, and improvement of quality of life. There was no significant difference between groups 1 and 2 in each index, but the patients in group 1 reported fewer problems than those in group 2. CONCLUSIONS: The application of kinesiology tape was helpful in reducing the postoperative inflammatory symptoms of mandibular third molar extraction and improved the patients' postoperative quality of life. These results suggest that kinesiology tape can be used as an auxiliary treatment to cryotherapy or as an alternative intervention after mandibular third molar extraction.

The aim of this study was to test two low-level laser therapy protocols by evaluating pain control, swelling and trismus in the postoperative period of lower third molar surgeries. This was a randomized, double-blind, placebo-controlled, crossover trial. Patients presenting two symmetrically impacted mandibular third molars were included. One side was randomly assigned for LLLT applied immediately after surgery (T1) and then after 24 (T2) and 48 hours (T3) (Protocol A). The other side received LLLT applied immediately after surgery and placebo after 24 and 48 hours (Protocol B). LLLT was given by intraoral application (660nm, 5 J/cm2, 10 s, 20 mW, 4 points) followed by extraoral application (789 nm, 30 J/cm2, 20 s, 60 mW, 8 points). The placebo application was similar to that of the experimental side but with laser simulation. The primary outcomes were pain control, swelling and trismus intensity at T1, T2, T3 and 7 days after surgery (T4). Data were analyzedbyANOVArepeated measures and Wilcoxon test (p<.05). The final sample consisted of 21 patients (42 teeth). There were no statistical differences for pain level between protocols A and B over time (p= .909), although the amount of analgesic medication was lower with protocol A at T2 (p=.022). There were no differences in swelling (p=.958) or trismus (p=.837) between the protocols used over time. Both protocols performed similarly for pain control, swelling and trismus. Therefore, for practical reasons, a single laser application in the immediate postoperative period could be indicated for the management of postoperative discomfort in lower third molar surgery.
O objetivo deste estudo foi testar dois protocolos de terapia com laser de baixa intensidade (LBI) para controle da dor, edema e trismo no período pós-operatório de cirurgias de terceiro molar inferior. Neste estudo randomizado, duplo-cego, controlado, de boca dividida foram incluídos pacientes que apresentavam os terceiros molares inferiores simetricamente. Um lado foi aleatoriamente designado para receber LBI aplicada imediatamente após a cirurgia (T1) e após 24 (T2) e 48 (T3) horas (Protocolo A). O lado oposto recebeu LBI imediatamente após a cirurgia e placebo após 24 e 48 horas (Protocolo B). A aplicação de LBI foi realizada intraoralmente (660nm, 5 J/cm2, 10 s, 20 mW, 4 pontos), seguida pela aplicação extraoral (789 nm, 30 J/cm2, 20 s, 60 mW, 8 pontos). O efeito do placebo foi similar ao experimental. Os desfechos primários eram dor, edema e intensidade do trismo nos tempos T1, T2, T3 e 7 após a cirurgia (T4). Os dados foram analisadosporANOVA e teste deWilcoxon (p<.05). A amostra final consistiu de 21 pacientes (43 dentes). Não houve diferença estatística para o nível de dor entre os protocolos A e B ao longo do tempo (p=.909), embora a quantidade de medicação analgésica tenha sido menor com o protocolo A em T2 (p= .022). Não houve diferença para edema (p=.958) ou trismo (p=.837) entre os protocolos ao longo do tempo. Em conclusão, a aplicação de LBI imediatamente após a cirurgia e após 24 e 48 horas (Protocolo A) apresenta melhor resultado para controle da dor. Ambos os protocolos foram similares para dor, edema e trismo. Portanto, por razões de praticidade, uma aplicação única de laser imediatamente após a cirurgia pode estar indicada para o manejo do desconforto pós-operatório em cirurgias de terceiros molares inferiores.

Peripheral nerve damages are among the most important consequences of dental and maxillofacial procedures. Tissue engineering using mesenchymal stem cells (MSCs) is a promising method to manage such injuries. Moreover, photobiomodulation therapy (PBMT) can enhance this treatment. The present study aimed to investigate the effect of PBMT on differentiation of MSCs derived from dental follicle (DF) into neurons. MSCs were isolated from an impacted tooth follicle by digestion method. The stem cells were cultured, and differentiated into neurons. The cells received two sessions of PBMT with 810 or 980 nm diode laser (100 mW, 4 J cm-2 ) in either DMEM or neural inductive medium. Phenotypic characterization of the cells was determined using flow cytometry. In addition, ß-tubulin and MAP2 genes expression level changes were analyzed using RT-PCR and western blot technique. After 14 days, flow cytometry analysis confirmed the mesenchymal nature of cells. RT-PCR and western blot affirmed the expression of ß-tubulin and MAP2 genes and proteins respectively. PBMT with both wavelengths significantly increased ß-tubulin and MAP2 expression in neural inductive medium with highest expression mean in 980 nm group. PBMT with 810 and 980 nm lasers could be a promising adjunctive method in differentiation of DF-originated MSCs into neural cells.

This systematic review aimed to evaluate the effectiveness of low-level laser therapy in controlling postoperative pain in lower third molar extractions. A search was carried out in MEDLINE/PubMed, Web of Science and Cochrane Library (CENTRAL) databases, using the "low-level laser therapy", "photobiomodulation therapy", "impacted mandibular third molar", "mandibular third molar", "third molar extraction" descriptors and 2625 studies were found, including only randomized clinical trials published until July 2020, with no restrictions on language and country of study. Selected studies were submitted to initial screening based on the reading of titles, abstracts and full article, and duplicate studies were excluded. Overall, 2562 articles were found, of which only 15 randomized clinical trials were included in this review. A total of 648 patients (16-44 years) who received low-level laser therapy as an intervention and placebo in their control group were evaluated. The pain evaluation criterion was the Visual Analog Scale (VAS) on the second and seventh days after surgery. Photobiomodulation with low-level laser showed statistically significant reduction in postoperative pain in lower third molar extractions, both on the second (MD: - 0.59; CI: - 0.92, - 0.27) and seventh day after surgery (MD: - 0.76; CI: - 1.21, - 0.32).

OBJECTIVES: Postoperative pain management impacts patients' quality of life and morbidity. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are widely used for this following a 3-doses-per-day regime. However, pain and inflammation follow a circadian rhythm, and animal models assessing the scheduling of NSAID administration (e.g., chronotherapy) have shown that while their use during the active phase of the day enhances postoperative recovery, their administration during the resting phase could have detrimental effects. This observation has led us to hypothesize that night administration of NSAID might be unnecessary in post-surgical scenarios. Therefore, a randomized clinical trial was conducted to test this hypothesis in surgical third molar extractions. MATERIALS AND METHODS: Seventy (18-35 years) healthy participants requiring surgical removal of impacted lower third molars were recruited and randomized into a double-blind placebo-controlled study. For three days postoperatively, the treatment group (n = 33) received ibuprofen (400 mg) at 8 AM, 1 PM, and a placebo at 8 PM, while the control group (n = 37) received ibuprofen (400 mg) at 8 AM, 1 PM, and 8 PM. Pain severity was assessed by visual analog scale (VAS) and healing indicators including facial swelling, mouth opening, and C-reactive protein blood levels were also measured. RESULTS: Pain VAS measures showed a circadian variation peaking at night. Also, no significant differences were observed between the two groups of the study in terms of postoperative pain scores (estimate: 0.50, 95% CI = [- 0.38, 1.39]) or any other healing indicator. CONCLUSIONS: Postoperative pain follows a circadian rhythm. Moreover, night administration of ibuprofen might not provide any significant benefits in terms of pain management and control of inflammation, and two doses during the day only could be sufficient for pain management after surgical interventions. KNOWLEDGE TRANSFER STATEMENT: Even though this study cannot rule out the possibility that a reduced regime is different than a standard regime, nocturnal doses of ibuprofen seem to have no clinical significance in the short term, and the results of this study provide evidence in favor of reducing ibuprofen administration from three doses to two doses only after third molar surgery.

PURPOSE: Laser light has biological effects that can modulate inflammatory processes. Thus, this study aimed to evaluate the effects of photobiomodulation (PBM) therapy on pain, edema, and trismus after the extraction of retained third molars. METHODS: A split-mouth, double-blind, randomized clinical trial (RCT) was conducted in 13 patients with similar bilateral third molars who received intraoral application PBM therapy at 4 points with a diode laser at 810 nm wavelength, 6 J (100 mW, 60 seconds/point) on 1 side (the PBM side); and laser irradiation simulation on the other side (SHAM side). The pain was assessed through visual analog scale (VAS) at 0, 12, 24, 48, and 72 hours, number of analgesic-relief (NAR), and mean time of first analgesic use; edema, through VAS, and linear facial measurements at 0, 24, 48, and 72 hours; and trismus, through the mouth opening measurements at 0, 24, 48, and 72 hours. The repeated-measures analysis was applied to assess the effect of the treatment, followed by Tukey's post hoc test for multiple comparisons (P < .05). RESULTS: Thirteen patients (61.77% male and 38.63% female) with age of 24.16 ± 2.06 participated in this research. VAS showed that PBM controlled pain better (7.56 ± 6.25) than SHAM (32.25 ± 22.78) at 24 hours (P < .001) and 48 hours (19.47 ± 9.27 and 39.87 ± 4.21, respectively) (P = .011). VAS also showed that PBM controlled edema better (19.7 ± 13.27) than SHAM (32.38 ± 15.28) at 24 hours (P = .037) and 48 hours (19.47 ± 13.11 and 39.87 ± 22.77, respectively) (P = .002). CONCLUSION: The PBM therapy in this study resulted in pain and edema reduction after third molar surgery and may be considered as adjuvant therapy after the surgical procedure.

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.

OBJECTIVE: The effects of the number of photobiomodulation (PBM) sessions on the postoperative inflammatory process remain controversial. The current literature comparing single and repeated PBM sessions is limited. This study aimed to compare the effects of single and repeated PBM sessions, applied at two different therapeutic wavelengths within the infrared spectrum, on postoperative inflammatory response after impacted third molar tooth extraction. METHODOLOGY: This randomized, double-blind clinical study included 40 patients with bilateral impacted mandibular third molars (80 teeth). The patients were divided into two groups each including 20 subjects (40 teeth) to receive either single-session laser at 810 nm (20 teeth) and 940 nm (20 teeth) immediately after the surgery or repeated laser sessions at 810 nm (20 teeth) and 940 nm (20 teeth) (immediately after the surgery and on postoperative Day 1). Lasers at 940 nm (power density 0.5 Watt/cm2, energy density 4 J/cm2 for a time until the cumulative energy on the device screen reaches 50 J from 0 J, in continuous mode, spot size 2.8 cm2) and at 810 nm (power density 0.14 Watt/cm2, energy density 4 J/cm2, for 30 seconds, in continuous mode, spot size 2.1 cm2) were applied intra- and extra-orally. Pain, swelling, and trismus were evaluated postoperatively. RESULTS: No significant differences were determined between the groups on the evaluated parameters (p>0.05). CONCLUSION: Within the study limitations, in PBM, the effects of 810 nm and 940 nm and those of single and repeated applications were similar regarding pain, swelling and trismus. Immediate postoperative PBM could be preferred to repeated applications performed by point application within a 24-hour period.

BACKGROUND: Results from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis. METHODS: The authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence. RESULTS: Patients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, -3.94 to -1.56) and at 7 days (95% CI, -1.67 to -0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of -0.44 at 24 hours, 0.63 at 72 hours, and -0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, -1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, -0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, -1.34 to 4.18; 4 studies, 133 patients). PRACTICAL IMPLICATIONS: Evidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.
