Comparative effectiveness of preemptive administration of ibuprofen and ibuprofen-arginine on the anesthetic success of inferior alveolar nerve block in teeth with symptomatic irreversible pulpitis - A double-blind randomized clinical trial. Clin Oral Investig 2024; 28:366. [PMID: 38850383 DOI: 10.1007/s00784-024-05765-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 06/03/2024] [Indexed: 06/10/2024]
Abstract
OBJECTIVES This study examined the impact of premedication with ibuprofen and ibuprofen-arginine and the influence of preoperative pain and anxiety on inferior alveolar nerve block (IANB) efficacy in cases of symptomatic irreversible pulpitis. MATERIALS AND METHODS The study involved 150 SIP patients who were randomly assigned to receive ibuprofen (600 mg), ibuprofen-arginine (1,155 mg), or a placebo 30 min before IANB. Preoperative anxiety and pain levels were assessed using the Modified Dental Anxiety Scale and the Heft-Parker visual scale. IANB efficacy was determined by the absence of or mild pain during the procedure. Statistical analysis included chi-square, z-tests, Analysis of Variance, and Student's t tests. RESULTS The ibuprofen and ibuprofen-arginine groups exhibited significantly higher IANB success rates (62% and 78%, respectively) compared to the placebo group (34%). However, no significant difference was observed between the ibuprofen and ibuprofen-arginine groups. Patients with successful IANB in the ibuprofen and ibuprofen-arginine groups displayed lower median anxiety scores (8) than those with failed blocks (15) and lower mean preoperative pain scores (118.3). CONCLUSION In cases of symptomatic irreversible pulpitis the preemptive medication with ibuprofen-arginine effectively increased the efficacy of the inferior alveolar nerve block The inferior alveolar nerve block efficacy was influenced by preoperative anxiety levels and the intensity of pain. CLINICAL RELEVANCE This research underscores the potential benefits of oral premedication with ibuprofen and ibuprofen-arginine in improving anesthesia outcomes in cases of symptomatic irreversible pulpitis.

Effect of Back-Pressure Anesthesia on Postoperative Pain after the Endodontic Treatment in Patients with Symptomatic Irreversible Pulpitis: Randomized Double-Blind Clinical Trial. J Endod 2024:S0099-2399(24)00300-5.

Abstract
INTRODUCTION The present study evaluated the effect of 2 different back pressure-based supplemental anesthesia on postoperative pain in patients receiving endodontic treatment for a mandibular molar with symptomatic irreversible pulpitis. METHODS One-hundred-thirty-five adult patients with symptomatic irreversible pulpits in a mandibular first or second molar, received an initial inferior alveolar nerve block (IANB) injection with 2% lidocaine with 1:80,000 epinephrine. Ten minutes following the injection, access to cavity preparation began. Lip numbness was a must for all patients. The Heft-Parker visual analogue scale (HP-VAS) was used to measure pain during endodontic therapy. Success of primary injections was defined as no or mild pain (less than 55 mm on HP-VAS) during access preparation. The patients with initial successful anesthesia served as control and received endodontic treatment. Ninety-five patients with unsuccessful primary anesthesia randomly received either intraligamentary injections of 2% lidocaine with 1:80,000 epinephrine or intrapulpal injections with similar anesthetic solution. Endodontic treatment was re-initiated and canals were instrumented till working length under copious irrigation. Intracanal medicament of calcium hydroxide was placed and teeth received a temporary restoration. Postoperative pain was measured at 2 hours, 4 hours, 6 hours, 24 hours, and 3 days. Data were analyzed using the Pearson chi-square test, one-way analysis of variance, and one-way repeated measures analysis of variance. RESULTS The initial initial inferior alveolar nerve block was successful in 40 cases (out of 135). The intraligamentary injections were successful in 33 out of 47 cases (70%), and intrapulpal injections were successful in all cases (45/45). The patients receiving intraligamentary injections reported significantly higher pain scores at all intervals till 24 hours. After 3 days, the pain significantly reduced in all the groups with no significant difference between them. CONCLUSIONS Patients receiving supplementary intraligamentary injections can experience increased postoperative pain till 24 hours after the endodontic treatment. The pain scores reduced to the level of the control group after 3 days.

Increased Purinergic Signaling in Human Dental Pulps With Inflammatory Pain is Sex-Dependent. THE JOURNAL OF PAIN 2024; 25:1039-1058. [PMID: 37956743 PMCID: PMC11129867 DOI: 10.1016/j.jpain.2023.10.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 09/22/2023] [Accepted: 10/28/2023] [Indexed: 11/15/2023]
Abstract
An enhanced understanding of neurotransmitter systems contributing to pain transmission aids in drug development, while the identification of biological variables like age and sex helps in the development of personalized pain management and effective clinical trial design. This study identified enhanced expression of purinergic signaling components specifically in painful inflammation, with levels increased more in women as compared to men. Inflammatory dental pain is common and potentially debilitating; as inflammation of the dental pulp can occur with or without pain, it provides a powerful model to examine distinct pain pathways in humans. In control tissues, P2X3 and P2X2 receptors colocalized with PGP9.5-positive nerves. Expression of the ecto-nucleotidase NTPDase1 (CD39) increased with exposure to extracellular adenosine triphosphate (ATP), implying CD39 acted as a marker for sustained elevation of extracellular ATP. Both immunohistochemistry and immunoblots showed P2X2, P2X3, and CD39 increased in symptomatic pulpitis, suggesting receptors and the ATP agonist were elevated in patients with increased pain. The increased expression of P2X3 and CD39 was more frequently observed in women than men. In summary, this study identifies CD39 as a marker for chronic elevation of extracellular ATP in fixed human tissue. It supports a role for increased purinergic signaling in humans with inflammatory dental pain and suggests the contribution of purines shows sexual dimorphism. This highlights the potential for P2X antagonists to treat pain in humans and stresses the need to consider sex in clinical trials that target pain and purinergic pathways. PERSPECTIVE: This article demonstrates an elevation of ATP-marker CD39 and of ATP receptors P2X2 and P2X3 with inflammatory pain and suggests the rise is greater in women. This highlights the potential for P2X antagonists to treat pain and stresses the consideration of sexual dimorphism in studies of purines and pain.

Abstract
OBJECTIVE The objective of this study was to evaluate the effectiveness of preoperative analgesics on inferior alveolar nerve blocks (IANB) during root canal treatment in patients with symptomatic irreversible pulpitis of the mandibular molars. METHODS This study was a randomized, double-blinded, superiority trial with a parallel study design. A total of 120 subjects with symptomatic irreversible pulpitis were randomly assigned to one of four groups: group A (con- trol, Vitamin E, Evion 400 mg), group B (Diclofenac sodium, Voltral SR100 100 mg), group C (Piroxicam, Feldene 20 mg), and group D (Tramadol, Tramal 50 mg). The patients recorded preoperative pain levels, and after admin- istration of local anaesthesia intraoperative pain levels using the Heft-Parker visual analogue scale before and after the oral administration of the analgesics. Statistical analysis was performed using the Kruskal-Wallis test. RESULTS All the analgesic groups showed a significant effect on the efficacy of the inferior alveolar nerve block in contrast to the control group (p<0.05). However, no significant difference was found between the drug groups on the effectiveness of the inferior alveolar nerve block (p>0.05). No side effects were reported in the present study. CONCLUSION Preoperative analgesics significantly increase the effectiveness of inferior alveolar nerve block in patients with symptomatic irreversible pulpitis. Therefore, preoperative analgesics should be considered to increase the effectiveness of inferior alveolar nerve block in patients with symptomatic irreversible pulpitis on the mandibular molars.

Cryotherapy and pain intensity during endodontic treatment of mandibular first permanent molars with symptomatic irreversible pulpitis: A randomized controlled trial. Clin Oral Investig 2023; 27:4585-4593.

Abstract
OBJECTIVES The study aimed to assess the effectiveness of cryotherapy application after inferior alveolar nerve block (IANB) administration of the mandibular first permanent molars with symptomatic irreversible pulpitis (SIP) in adolescence. The secondary outcome was to compare the need for supplemental intraligamentary injection (ILI). MATERIALS AND METHODS The study was designed as a randomized clinical trial including 152 participants aged from 10 to 17 years who were randomly assigned to two equal groups; cryotherapy plus IANB (intervention group) and the control group (conventional INAB). Both groups received 3.6 mL of 4% articaine. For the intervention group, ice packs were applied in the buccal vestibule of the mandibular first permanent molar for 5 min. Endodontic procedures started after 20 min for efficiently anesthetized teeth. The intraoperative pain intensity was measured using the visual analogue scale (VAS). The Mann-Whitney (U) and chi-square tests were applied to analyze data. The significance level was set to 0.05. RESULTS There was a significant reduction in the overall intraoperative VAS mean in the cryotherapy group compared to that in the control group (p = 0.004). The success rate was significantly higher in the cryotherapy group (59.2%) compared to the control group (40.8%). The frequency of extra ILI was 50% and 67.1% in the cryotherapy and control groups, respectively (p = 0.032). CONCLUSIONS The cryotherapy application boosted the efficacy of pulpal anesthesia of the mandibular first permanent molars with SIP in patients below the age of 18 years. Additional anesthesia was still necessary for optimal control over pain. CLINICAL RELEVANCE Pain control during endodontic treatment of primary molars with irreversible pulpitis (IP) is a significant factor in a child's behavior in the dental office. Although the inferior alveolar nerve block (IANB) is the most commonly used technique to anaesthetize mandibular dentition, we found its success rate to be relatively low during endodontic treatment of primary molars with IP. Cryotherapy is a new approach that significantly improves the efficacy of IANB. CLINICAL TRIAL REGISTRATION The trial was registered at ClinicalTrials.gov (reference no. NCT05267847).

Abstract
AIM The aim of this study was to assess and compare the pain during infiltration by a modified two-stage local anesthetic infiltration technique under topical anesthesia (TA). MATERIALS AND METHODS In this cross-over double-blind study, 30 volunteers participated, where two groups were given single-stage infiltration and the other two had two-stage infiltrations. Depending upon the infiltration technique (one- or two-stage) and the use of TA, the patients were randomly divided into four groups. Local anesthesia (LA) was administered by infiltration into the mucobuccal fold of the maxillary central incisor, and the pain perceived during the infiltration in each group was recorded. The volunteers were recalled after 24 hours to assess the tenderness at the injection site. The volunteers were recalled 2 weeks after infiltration for the subsequent groups to assess the pain for this cross-over study. RESULTS A statistically significant difference was observed in the pain perceived when TA was used and when the infiltration was done in two stages. Regarding the pain at the site of injection after 24 hours, no significant difference was observed among the volunteers. CONCLUSION Topical anesthesia was effective in reducing the pain of injection when compared to placebo. The pain of injection is further reduced with a two-stage infiltration technique after TA application. CLINICAL SIGNIFICANCE Topical anesthesia can be used routinely before infiltration, and LA infiltration injections are less painful if administered in two stages.

Abstract
INTRODUCTION The present study aimed to investigate the possible association between the single-nucleotide polymorphisms (SNPs) in the SCN9A, SCN10A, SCN11A, OPRM1, and COMT genes and the success rate of pulpal anesthesia after inferior alveolar nerve block (IANB). METHODS A total of 70 patients (45 females and 25 males) presenting mandibular molar teeth with symptomatic irreversible pulpitis were included. Saliva samples were collected from the participants before the application of IANB. A standard IANB was performed with 1.8 mL 4% articaine with 1:100,000 epinephrine. Endodontic treatment was initiated 15 minutes after injection, and the patients were asked to report their pain level during the procedure on a 170-mm Heft-Parker visual analog scale. If the patient recorded a pain level of lower than 54 on the visual analog scale (no pain or mild pain), the anesthesia was considered successful. The DNA isolation and genotyping were performed, and the association between rs4286289, rs6746030, rs6795970, rs6801957, rs11709492, rs1799971, rs1799973, rs4680, rs6269, rs4633, and rs740603 SNPs and the success rate of anesthesia was investigated. RESULTS The anesthesia success rate was significantly lower for the GG genotypes (45%) than the GA and AA genotypes (90%) for rs6795970 in the SCN10A gene. Additionally, the A allele for rs6795970 and the T allele for rs6801957 in the SCN10A gene were significantly associated with higher anesthesia success rates. CONCLUSIONS SNPs in the SCN10A gene affect the success rate of pulpal anesthesia after IANB.

Abstract
AIM To assess inferior alveolar nerve block (IANB) success of 2% mepivacaine (Scandonest 2%, Septodont, France) and 4% articaine (Septanest 4%, Septodont) in patients with symptomatic irreversible pulpitis (SIP) in mandibular molars during access cavity preparation and instrumentation. METHODOLOGY Three hundred and thirty patients with moderate-to-severe pain in mandibular molars with SIP randomly received either 3.6 mL 2% mepivacaine hydrochloride with 1:100 000 adrenalin or 3.4mL 4% articaine hydrochloride with 1:100 000 adrenalin (n=165). Intraoperative pain (IOP) intensity was assessed during access cavity preparation and canal instrumentation using 11-point numerical rating scale (NRS). Overall success was considered if the patient felt no-to-mild pain without the need of supplemental anaesthesia throughout treatment; the incidence of need for supplemental anaesthesia was also recorded. Data were statistically analyzed using Mann Whitney U and Chi2 (χ2 ) tests. Relative risk (RR) and 95% confidence interval (CI) of anaesthetic failure was calculated. The effect of predisposing factors on outcome variables was assessed using multivariable regression analyses. None of the participants reported any adverse effects. RESULTS Baseline variables were balanced between groups (p>0.05). The IOP intensity during access cavity preparation and canal instrumentation was similar for both groups (p>0.05). IOP intensity was associated with preoperative pain intensity and tooth type (p<0.05). Overall anaesthetic success rate was 35.8% for mepivacaine and 41.2% for articaine (p>0.05) with a relative risk of failure [95%CI] 1.09 [0.92, 1.30]. The need for supplemental anaesthesia occurred 43.6% and 38.2% with mepivacaine and articaine respectively (p>0.05; RR [95%CI]: 1.14 [0.88, 1.48]). Preoperative pain level and age were associated with the need for supplemental anaesthesia. CONCLUSIONS 2% mepivacaine and 4% articaine demonstrate similar IANB success rates for mandibular molars with SIP. Intraoperative pain experience during endodontic treatment can be associated with preoperative pain, tooth type and age.

Addition of 2 mg dexamethasone to improve the anesthetic efficacy of 2% lidocaine with 1:80,000 epinephrine administered for inferior alveolar nerve block to patients with symptomatic irreversible pulpitis in the mandibular molars: a randomized double-blind clinical trial. J Dent Anesth Pain Med 2022; 22:305-314. [PMID: 35991360 PMCID: PMC9358268 DOI: 10.17245/jdapm.2022.22.4.305] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2022] [Revised: 07/08/2022] [Accepted: 07/11/2022] [Indexed: 11/28/2022] Open
Abstract
Introduction This clinical trial aimed to evaluate the anesthetic effect of the addition of 2 mg (4 mg/ml) of dexamethasone to 2% lidocaine (plain or with 1:80,000 epinephrine). The solutions were injected for a primary inferior alveolar nerve block (IANB) to provide mandibular anesthesia for the endodontic treatment of mandibular molars with symptomatic irreversible pulpitis. Methods In a double-blinded setup, 124 patients randomly received either of the following injections: 2% lidocaine with 1:80,000 epinephrine, 2% lidocaine with 1:80,000 epinephrine mixed with 2 mg dexamethasone, or plain 2% lidocaine mixed with 2 mg dexamethasone, which were injected as a primary IANB. Ten minutes after injection, patients with profound lip numbness underwent electric and thermal pulp sensibility tests. Patients who responded positively to the tests were categorized as "failed" anesthesia and received supplemental anesthesia. The remaining patients underwent endodontic treatment using a rubber dam. Anesthetic success was defined as "no pain or faint/weak/mild pain" during endodontic access preparation and instrumentation (HP visual analog scale score < 55 mm). The effect of the anesthetic solutions on the maximum change in heart rate was also evaluated. The Pearson chi-square test at 5% and 1% significance was used to analyze anesthetic success rates. Results The 2% lidocaine with 1:80,000 epinephrine, 2% lidocaine with 1:80,000 epinephrine mixed with 2 mg dexamethasone, and plain 2% lidocaine mixed with 2 mg dexamethasone groups had anesthetic success rates of 34%, 59%, and 29%, respectively. The addition of dexamethasone resulted in significantly better results (P < 0.001, χ2 = 9.07, df = 2). Conclusions The addition of dexamethasone to 2% lidocaine with epinephrine, administered as an IANB, can improve the anesthetic success rates during the endodontic management of symptomatic mandibular molars with irreversible pulpitis.

Parirokh M, Abbott P. Present status and future directions - Mechanisms and management of local anaesthetic failures. Int Endod J 2022; 55 Suppl 4:951-994. [PMID: 35119117 DOI: 10.1111/iej.13697] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2021] [Revised: 01/30/2022] [Accepted: 02/01/2022] [Indexed: 11/05/2022]
Abstract
Pain control during root canal treatment is of utmost importance for both the patient and the dental practitioner and many studies have investigated ways of overcoming problems with gaining adequate anaesthesia during treatment. The PubMed and Cochrane databases were searched for evidence-based studies regarding local anaesthesia for root canal treatment. Many variables, including premedication, pain during needle insertion, pain on injection, premedication with various types of drugs, volume of anaesthetic solutions, supplemental anaesthetic techniques, and additives to the anaesthetic solutions, may influence pain perception during root canal treatment. Differences between teeth with healthy pulps versus those with irreversible pulpitis should be considered when the effects of variables are interpreted. There are several concerns regarding the methodologies used in studies that have evaluated anaesthesia success rates. There are some conditions that may help to predict a patient's pain during root canal treatment and these conditions could be overcome either by employing methods such as premedication with a non-steroidal anti-inflammatory drug prior to the treatment visit or by using supplementary anaesthetic techniques before or during the treatment. However, authors need to be more careful when reporting details of their studies to reduce concerns regarding their study bias.

Abstract
Smoking is harmful to all organs of the human body and can affect nerve response to local anesthesia. This study aimed to determine the effect of cigarette smoking on the amount and onset of local anesthesia, as well as the chief complaint (symptomatic and asymptomatic), number of cigarettes, and duration of smoking. Materials and methods A selective clinical case-control study carried out at the Oral Surgery Clinic of the Teaching Hospital at the College of Dentistry. One hundred and three male patients participated in the study, and they were divided into two groups (55 smokers and 48 nonsmokers). The patients received a local anesthetic agent (2% Lidocaine) in a 1.8 ml dental cartridge. The number of cartridges and the onset time of local anesthesia were detailed for each patient in a special case sheet prepared for this study. Results There was a statistically significant difference between the smoker and nonsmoker groups regarding the amount of local anesthetic solution (p = .041) with a higher amount needed in the smoker group; however, the onset of action showed no significant difference between the two groups (p = 0.983). The symptomatic cases in smokers needed a higher amount of local anesthesia than the asymptomatic cases with a statistically significant difference (p = 0.002). There was no relationship between daily cigarette consumption and the amount of local anesthetic solution (p = .054) and also the onset of local anesthesia (p = .938). The duration of smoking has no significant relationship with onset time (p = .480) and the amount of local anesthesia (p = .418). Conclusion The amount of local anesthesia used in smoker patients was higher than that in nonsmoker patients, especially if there were symptoms like pain. The duration of smoking and daily cigarette consumption had no effect on the amount and the onset of local anesthesia.

Abstract
Local anesthesia (LA) is the most important pain management process in oral and maxillofacial surgery. Safe and effective LA not only enable patients to obtain high-quality treatment, but also relieve the anxiety of patients when they come to the clinic. The choices of local anesthetic and injection methods determine the success of LA to a great extent. At present, in most countries or regions, common local anesthetics used in oral and maxillofacial surgery belong to amides and they are injected into patients' body mainly through block or infiltration anesthesia. In addition, the operators' technique level, patient's subjective psychology and anatomical variation of maxillofacial structure also have a strong influence on LA in dental clinic. Due to the existence of above factors, the worldwide success rates of LA in oral and maxillofacial surgery is very different. There are no specific LA methods that ensure 100% successful LA rates. Fortunately, the development of new local anesthetic and injection technology are providing us with new ideas to solve this problem. This review mainly report the new research progress on LA in oral and maxillofacial surgery in recent decades and help clinicians with dental LA operation.

The effect of pre-operative submucosal administration of dexamethasone, tramadol, articaine on the success rate of inferior alveolar nerve block on mandibular molars with symptomatic irreversible pulpitis: A randomized, double-blind placebo-controlled clinical trial. Int Endod J 2021; 54:1982-1992. [PMID: 34347895 DOI: 10.1111/iej.13604] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 07/28/2021] [Accepted: 08/03/2021] [Indexed: 11/28/2022]
Abstract
AIM To establish the effects of submucosal tramadol, dexamethasone and articaine on the success of inferior alveolar nerve blocks (IANB) during root canal treatment of mandibular molars with symptomatic irreversible pulpitis (SIP). METHODOLOGY In this randomized double-blind, controlled clinical trial, 120 patients with the diagnosis of SIP in their mandibular first or second molars were included and randomly divided into four groups (n = 30). The control group received normal saline and three experimental groups received a single dose of dexamethasone (8 mg/2 mL), or tramadol (100 mg/2 mL) or articaine (4% / 2 mL). The pre-operative pain levels of the patients were measured with the Heft-Parker visual analogue scale (HP VAS). All patients received standard IANB of 4% articaine with 1:200000 epinephrine. Following the observation of lip numbness, submucosal injections were administered into the mucobuccal fold adjacent to the mandibular molars. After 15 min, standard root canal treatment was initiated, and the pain intensity levels recorded from the access cavity preparation to pulp extirpation were measured with HP VAS. The duration of the anaesthesia was also evaluated. The experimental groups were compared using one-way ANOVA or Kruskal-Wallis H-test. The groups that were significantly different were compared pairwise using the Tukey Multiple Comparison test. The Chi-square test was used to compare the categorical variables. RESULTS The submucosal administration of articaine significantly increased the success rate to 63% in comparison with the control group that received submucosal saline (p < .05). The success rate of pulpal anaesthesia was 37% in the control group, 57% in the tramadol group and 47% in the dexamethasone group, with no significant difference in the success rate among these groups. In the dexamethasone group, the duration of the anaesthetic effect of IANB was significantly longer than those in the other groups (p < .001). CONCLUSIONS In patients with SIP, pre-operative submucosal administration of articaine increased the success rate of IANB, while administration of dexamethasone increased the duration of anaesthesia. These agents can be used in cases where effective anaesthesia cannot be obtained during root canal treatments.

Abstract
This randomized, active-controlled, double-blind, prospective clinical trial evaluated the anesthetic efficacy of 2% lidocaine with 1:200,000 epinephrine versus an admixture of 2% lidocaine with 1:200,000 epinephrine and 1 mL of 4 mg dexamethasone (Twin mix) for inferior alveolar nerve blocks (IANBs) in patients with symptomatic irreversible pulpitis (SIP) of the mandibular molars. Seventy-eight patients with SIP of mandibular molars were randomly allocated to the 2 groups of 39 subjects. All patients were required to have profound lip numbness within 10 minutes of local anesthetic deposition. The efficacy of pulpal anesthesia was confirmed by absence of pain or mild pain (Heft-Parker visual analogue scale ≤54 mm) during access cavity preparation and placement of glide path files. The collected data were subjected to independent t test, chi-square test, and Fisher exact test using SPSS software version 20.0 at a significance level of 0.05. IANB success rates for the lidocaine group and the Twin mix group was 66% and 68% respectively, which was not a statistically significant difference (p > .05). This study demonstrated that the anesthetic efficacy of Twin mix was equivalent to 2% lidocaine for IANBs in teeth with SIP.

Abstract
INTRODUCTION The aim of this randomized, double-blind clinical trial was to evaluate the effect of preoperative administration of intraligamentary injections of diclofenac sodium and dexamethasone on the anesthetic efficacy of 2% lidocaine given as an inferior alveolar nerve block in the endodontic management of symptomatic irreversible pulpitis. METHODS One hundred seventeen patients randomly received 1 of the 3 intraligamentary injections before the endodontic treatment: 0.9% normal saline, 25 mg/mL diclofenac sodium, or 4 mg/mL dexamethasone. After 30 minutes, patients received an inferior alveolar nerve block with 2% lidocaine and 1:80,000 epinephrine. The teeth were tested with electric pulp testing after 10 minutes. In case of a positive response, the anesthesia was considered as "failed." If the electric test response was negative, a rubber dam was applied, and endodontic treatment was started. Any pain during the treatment was recorded. The anesthesia was considered successful if the patients experienced no pain or faint/weak/mild pain during root canal access preparation and instrumentation (Heft-Parker visual analog scale score <55 mm). The effect of intraligamentary injections on maximum heart rates was also recorded. The anesthetic success rates were analyzed with the Pearson chi-square test at 5% significance. RESULTS The control, diclofenac sodium, and dexamethasone groups had anesthetic success rates of 32%, 37%, and 73%, respectively. Dexamethasone was significantly more successful than the control and diclofenac sodium groups (P < .001, χ22 = 14.7). There were no differences between the control and diclofenac groups (P > .05). All the solutions did not significantly affect heart rates. CONCLUSIONS The administration of an intraligamentary injection of dexamethasone before endodontic intervention of mandibular molars with symptomatic irreversible pulpitis increases the success rates of an inferior alveolar nerve block with 2% lidocaine.

Abstract
Objectives To investigate the success rate of supplemental intraseptal and buccal infiltration anaesthesia in mandibular molars undergoing endodontic therapy/extraction when the inferior alveolar nerve block has failed. Material and Methods A prospective clinical trial including 200 patients undergoing lower molar root canal treatment/teeth extraction was conducted. Only 80 patients of the participants who had profound lower lip anaesthesia after the administration of inferior alveolar nerve block (IANB) were in pain within treatment. Patients experiencing moderate to severe pain upon using elevators, forceps, bur, or endodontic file were randomly allocated to the 2% lidocaine intraseptal injection and 4% articaine buccal infiltration groups. Level of pain was assessed every 2 to 10 min on standard 100 mm visual analogue scales. Results Overall, 55 (69%) of patients who were given either intraseptal injection of 2% lidocaine or buccal infiltration of 4% articaine had successful anaesthesia of lower molar teeth within 10 min. However, 25 (31%) of participating patients in the buccal infiltration and the intraseptal groups had failed anaesthesia within the study duration (10 min), and they received additional local anaesthetic. IANBs were more painful than buccal and intraseptal injections. However, buccal articaine injections were significantly more comfortable than intraseptal lidocaine injections (P > 0.001). Conclusions Supplemental intraseptal injection of 2% lidocaine and buccal infiltration of 4% articaine achieved profound pulpal anaesthesia in 69% of patients when the inferior alveolar nerve block failed. Recommendations can be given to dental practitioners to use infiltration of 4% articaine in conjunction with intraseptal injection of 2% lidocaine to anaesthetize the lower molar teeth when inferior alveolar nerve block fails.

Abstract
Introduction: The present study evaluated the anaesthetic efficacy of 2% lidocaine with 1:80,000 epinephrine vs. 2% lidocaine with 1:200,000 given as supplemental intraligamentary injections after a failed inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. The effect of these solutions on the heart rate was also evaluated.Methods: One-hundred-eighteen adult patients with symptomatic irreversible pulpits in a mandibular first or second molar, received an initial IANB with 2% lidocaine with 1:80,000 epinephrine. Pain during the endodontic treatment was assessed using a visual analogue scale (Heft-Parker VAS). Eighty-eight patients with unsuccessful anaesthesia were randomly allocated to one of the two treatment groups: one group received 0.6 mL/root of supplementary intraligamentary injection of 2% lidocaine with 1:80,000 epinephrine; while the second group received 2% lidocaine with 1:200,000 epinephrine. Endodontic treatment was re-initiated. Success after primary injection or supplementary injection was defined as no or mild pain (pain score ≤54 mm on HP VAS) during access preparation and root canal instrumentation. Heart rate was monitored using a finger pulse oximeter. The anaesthetic success rates were analyzed with the Pearson chi-square test at 5% significance levels. The heart rate changes were analyzed using the t-test.Results: The anaesthetic success rate in patients receiving supplementary intraligamentary injections in 1:80,000 epinephrine group was 82%, while the intraligamentary injections with 2% lidocaine with 1:200,000 epinephrine were successful in 57% of cases. The difference was statistically significant (χ2=6.4, p = .011). There was no significant effect of both the anaesthetic agents on the mean heart rate.Conclusions: Both 2% lidocaine with 1:80,000 epinephrine and 2% lidocaine with 1:200,000 epinephrine improved the success rates after a failed primary anaesthetic injection. The 1:80,000 epinephrine group was significantly more successful.

Abstract
Background Local anesthetics alone or in combination with adjuncts, such as oral medications, have routinely been used for pain control during endodontic treatment. The best clinical choice amongst the vast numbers of agents and techniques available for pain control for irreversible pulpitis is unclear. This network meta-analysis combined the available evidence on agents and techniques for pulpal anesthesia in the maxilla and mandible, in order to identify the best amongst these approaches statistically, as a basis for future clinical trials. Methods Randomized trials in MEDLINE, DARE, and COCHRANE databases were screened based on inclusion criteria and data were extracted. Heterogeneity was assessed and odds ratios were used to estimate effects. Inconsistencies between direct and indirect pooled estimates were evaluated by H-statistics. The Grading of Recommendation, Assessment, Development, and Evaluation working group approach was used to assess evidence quality. Results Sixty-two studies (nine studies in the maxilla and 53 studies in the mandible) were included in the meta-analysis. Increased mandibular pulpal anesthesia success was observed on premedication with aceclofenac + paracetamol or supplemental 4% articaine buccal infiltration or ibuprofen+paracetamol premedication, all the above mentioned with 2% lignocaine inferior alveolar nerve block (IANB). No significant difference was noted for any of the agents investigated in terms of the success rate of maxillary pulpal anesthesia. Conclusion Direct and indirect comparisons indicated that some combinations of IANB with premedication and/or supplemental infiltration had a greater chance of producing successful mandibular pulpal anesthesia. No ideal technique for maxillary anesthesia emerged. Randomized clinical trials with increased sample size may be needed to provide more conclusive data. Our findings suggest that further high-quality studies are required in order to provide definitive direction to clinicians regarding the best agents and techniques to use for mandibular and maxillary anesthesia for irreversible pulpitis.

Abstract
BACKGROUND The authors of this systematic review and meta-analysis aimed to evaluate the effect of different anesthetics on the efficacy of inferior alveolar nerve block (IANB) in patients with irreversible pulpitis. TYPES OF STUDIES REVIEWED The authors conducted a search of MEDLINE databases (PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, Latin American and Caribbean Health Sciences Literature, and Brazilian Library of Dentistry). There was no restriction on publication year or idiom. The gray literature was also explored. The authors included only randomized clinical trials that compared different anesthetics in the efficacy of IANB in patients with irreversible pulpitis. The risk of bias was evaluated by using the Cochrane Collaboration's tool. A random-effects Bayesian mixed treatment comparison model was used to compare different anesthetic solutions in randomized clinical trials with low or unclear risk of bias. Heterogeneity was assessed by using Cochran Q test and I2 statistics. Quality of evidence was assessed by using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS A total of 7,981 studies were identified; only 16 met the eligibility criteria, and they were all meta-analyzed. A significant difference was observed in the pair lidocaine versus articaine, with higher success with articaine (risk ratio, 0.76; 95% confidence interval, 0.63 to 0.88) in the mixed treatment comparison analysis, as this comparison was graded as high-quality evidence. The probability of success for each treatment was 73% for articaine, 57% for prilocaine, 55% for mepivacaine, 53% for bupivacaine, and 12% for lidocaine. This ranking was considered high quality of evidence. CONCLUSIONS AND PRACTICAL IMPLICATIONS The use of articaine can increase the IANB success rate in patients with irreversible pulpitis. Among the anesthetic solutions, lidocaine was the least effective.

Objective The aim of this study was to compare the anesthetic efficacy of two volumes of articaine in conventional inferior alveolar nerve block (IANB) of mandibular molars with irreversible pulpitis, and in cases of anesthetic failure, its complementation with periodontal ligament injection (PDL). Methods Ninety patients with irreversible pulpitis in mandibular molars received conventional IANB with 1.8 mL or 3.6 mL of 4% articaine with 1:100,000 epinephrine. In cases of IANB failure, the same volumes were administered in the PDL. Presence of pulpal anesthesia and absence/presence of pain during pulpectomy were evaluated by electric pulp stimulation and verbal analogue scale, respectively. Relative risks (RR) with corresponding 95% confidence intervals (95% CI) were calculated for each outcome. Results 27% and 42% of the patients achieved pulpal anesthesia following IANB with 1.8 mL and 3.6 mL, respectively (RR = 0.63, CI 95% 0.35 to 1.14, p = 0.12). Analgesia during pulpectomy was present in 64% and 73% of the patients, respectively, for 1.8 mL and 3.6 mL (RR = 0.87, CI 95% 0.66 to 1.16, p = 0.36). In cases of IANB failure, 75% and 42% of the patients that received 1.8 mL and 3.6 mL of PDL injection, respectively, achieved pulpal anesthesia (RR = 1.80, CI 95% 0.87 to 3.72, p = 0.11). During a new attempt at the pulpectomy procedure, analgesia was present in 69% and 75% of the patients, respectively, for 1.8 mL and 3.6 mL (RR = 0.91, CI 95% 0.57 to 1.45, p = 0.71). Conclusion Increasing the volume from 1.8 mL to 3.6 mL of the 4% articaine with 1:100,000 epinephrine in the IANB and in the PDL, did not significantly increase the success rate of pulpal anesthesia and clinical analgesia during the pulpectomy procedure. Therefore, both volumes presented a similar efficacy, though neither resulted in effective pain control during irreversible pulpitis treatment. Trial registration ClinicalTrials.gov NCT02422823.

Abstract
Administration of local anesthetics is daily routine for most dental practitioners. Normally, the effect is achieved, and no adverse effects are seen. In this article, the authors describe the complications of immediate, intense and shooting pain, numbness, and marked pallor of the cheek, which occurred during infiltration of a local anesthetic in buccal vestibule infiltration. The patients moved suddenly because of pain and marked pallor of the cheek near the root of the nose and lower eyelid pallor was observed. The pain was very short and the injection was performed again after a few minutes. Two patients also reported an alteration of vision or paralysis of the extra-ocular muscles and drooping eyelid due to paralysis of the levator palpebrae superioris muscle and signs of numbness in the infraorbital area on the same side as the anesthesia. While 3 patients were also apprehensive and started to scare with heart palpitations, as they did not understand what was happening. Probably the anesthetic solutions were injected into an intravascular artery and passed from the extraosseous branch of posterior superior alveolar artery through to the infraorbital artery, which could produce the clinical signs observed in the present study. At the same time, the inoculation of anesthetic in the artery could be grounds for legal disputes for the dentist. In fact, in the absence of vascular disease, anomalies documented by the dentist, they would, however, respond to professional liability and be liable for damages caused to the patient. In conclusion, despite the fact that this condition requires no treatment, it could lead to the recognition of clinical signs in patient with injection of local anesthesia into the artery. At the same time, the inoculation of anesthetic in the artery could be grounds for legal disputes for the dentist.

Abstract
Introduction The failure rate of inferior alveolar nerve (IAN) block is high for mandibular molars with irreversible pulpitis. This double-blind, randomized, clinical trial aimed to assess the effect of topical application of Dentol drop on the rate of successful anaesthesia of mandibular molars with irreversible pulpitis due to deep carious lesions. Methods and Materials Seventy-two patients with mandibular first and second molars with irreversible pulpitis and deep cavitated carious lesions participated in this study. The patients were randomly assigned to the test and control groups (n=36). In the test group, a cotton pellet, dipped in Dentol drop, was placed in the cavity for 10 min. A placebo was used _in the same manner_ in the control group. Level of pain was measured before the intervention, 15 min after anaesthesia (when patients reported numbness at the corner of the mouth), during access cavity preparation, upon pulp exposure and after introduction of the initial file into the root canal; using a Heft-Parker "Visual Analog Scale" (VAS). Data were analysed using ANCOVA. Results Levels of pain were recorded during access cavity preparation (P<0.001), pulp exposure (P<0.001) and file introduction into the canal (P=0.018). In the test (Dentol) group, the obtained levels of pain were significantly lower than those of the corresponding values in the control group. Conclusion Topical application of Dentol drop increased the success rate of IAN block for root canal treatment of mandibular molars with irreversible pulpitis.

Abstract
The aim of this study was to compare preventive ibuprofen administration to placebo on the efficacy of inferior alveolar nerve block in patients with irreversible pulpitis. A search was performed in PubMed, Scopus, Web of Science, LILACS, BBO, Cochrane Library, SIGLE, and grey literature. The risk of bias was evaluated through the Cochrane Collaboration's tool. The quality of evidence was assessed using the GRADE approach. Only seven studies remained for the meta-analysis. Administering ibuprofen before anaesthesia increased the success rate of injectable anaesthesia (RR = 1.79; 95% confidence interval (CI) 1.32-2.42; P = 0.0002) even in cases of symptomatic irreversible pulpitis (RR = 1.55; 95% CI 1.05-2.29; P = 0.03). The intensity of pain was lower for ibuprofen (standardised difference means (SMD) = -3.73; 95% CI -6.43 to -1.04; P = 0.007). Ibuprofen as premedication is beneficial for the success of inferior alveolar nerve block.

Abstract
This prospective observational study sought to investigate the incidence of intraoperative pain (IOP) among emergency endodontic patients and to construct an IOP prediction model that includes preoperative pain level (PPL). All patients who underwent emergency endodontic treatment at Gazi University, Ankara, Turkey, during the spring term of 2016 were considered for inclusion in the study. Demographic and clinical variables and PPL were recorded. Local anesthesia was provided to all patients before beginning routine endodontic treatment. IOP was defined as the condition of requiring supplementary anesthesia before the working length was established and exhibiting persistent moderate or severe pain despite supplementary anesthesia. Data from 85% and 15% of 435 patients (178 men, 257 women; mean age: 35 years) were used to develop predictive models by multiple logistic regression analysis and to test external validity of the models, respectively. Two multiple logistic regression models achieved good model fits. Model 1 included age, pulpal diagnosis, and arc (p < 0.05). In addition to these variables, Model 2 included periapical diagnosis and PPL (p < 0.15). Models 1 and 2 showed accuracies of 0.76 and 0.75, sensitivities of 0.74 and 0.77, and specificities of 0.76 and 0.74, respectively for the modeling data (internal validity), and accuracies of 0.82 and 0.80, sensitivities of 0.83 and 0.67, and specificities of 0.81 and 0.81, respectively for the control data (external validity). The IOP incidence was 10.3%. IOP in patients undergoing emergency endodontic treatment can be successfully predicted by using models that account for demographic and clinical variables, including PPL.

Abstract
This systematic review (SR; PROSPERO database: CRD42017075160) and network meta-analysis (NMA) identified the most effective oral premedication for anaesthetic success of inferior alveolar nerve blocks (IANB) in cases of irreversible pulpitis. Medline and Ebscohost databases were searched up until 10/2017. Randomized controlled trials (RCT) studying the effect of oral premedication, alone or in combination, on the success of IANB for cases of irreversible pulpitis, compared to placebo or other oral premedications, were included. Quality of the included studies was appraised by the revised Cochrane risk of bias tool for randomized trials. Pairwise analysis, NMA and quality of evidence assessment using GRADE criteria were performed. Nineteen studies (n = 1654 participants) were included. NMA demonstrated that compared to placebo, dexamethasone was most effective in increasing anaesthetic success (RR, 2.92 [95% CI 1.74,4.91]; SUCRA = 0.96), followed by NSAIDs (RR, 1.92 [95% CI 1.63,2.27], SUCRA = 0.738) and Tramadol (RR, 2.03 [95% CI 1.18,3.49], SUCRA = 0.737). Premedication with acetaminophen added to NSAIDs demonstrated similar efficacy as NSAIDs alone (RR, 1.06 [95% CI 0.79,1.43]). Sensitivity analyses proved the superiority of dexamethasone or NSAIDs over any other premedications. Subgroup analyses of specific dosages in comparison with placebo demonstrated that dexamethasone 0.5 mg was most effective, followed by ketorolac 10 mg, piroxicam 20 mg, ibuprofen 400 mg + acetaminophen 500 mg and Tramadol 50 mg. Ibuprofen 400 mg, 600 mg and 800 mg had a significantly improved IANB success, while Ibuprofen 300 mg had no effect. Oral premedication with dexamethasone, NSAIDs or Tramadol significantly increased anaesthetic success. More trials are needed to evaluate the premedication effects of dexamethasone or Tramadol for improved anaesthetic success of IANB when treating irreversible pulpitis.

Abstract
AIM To investigate the efficacy of 0.2 mL vs. 0.6 mL of 2% lidocaine when given as a supplementary intraligamentary injection after a failed inferior alveolar nerve block (IANB). METHODOLOGY Ninety-seven adult patients with symptomatic irreversible pulpits received an IANB and root canal treatment was initiated. Pain during treatment was recorded using a visual analogue scale (Heft-Parker VAS). Patients with unsuccessful anaesthesia (n = 78) randomly received intraligamentary injection of either 0.2 mL or 0.6 mL of 2% lidocaine with 1 : 80 000 epinephrine. Root canal treatment was reinitiated. Success after primary injection or supplementary injection was defined as no or mild pain (HP VAS score ≤54 mm) during access preparation and root canal instrumentation. Heart rate was monitored using a finger pulse oximeter. The anaesthetic success rates were analysed with Pearson chi-square test at 5% significance levels. The heart rate changes were analysed using t-tests. RESULTS The intraligamentary injections with 0.2 mL solution gave an anaesthetic success rate of 64%, whilst the 0.6 mL was successful in 84% of cases with failed primary IANB. (χ2 = 4.3, P = 0.03). There was no significant effect of the volume of intraligamentary injection on the change in heart rate. CONCLUSIONS Increasing the volume of intraligamentary injection improved the success rates after a failed primary anaesthetic injection.
