Abstract
This double-blind, randomised clinical trial aimed to find out whether there is a difference in the prevalence of neurosensory disturbance (NSD) between patients who received 2% lidocaine and those who received 4% articaine during inferior alveolar nerve blocks (IANBs). Patients who underwent third molar extraction were randomised into two groups. IANB was performed using 2% lidocaine in Group 1 and 4% articaine in Group 2. The occurrence of NSD was documented. Patients were visited within 48 hours and one week after the tooth was removed. The type of anaesthetic drug (4% articaine versus 2% lidocaine) was the study's predictive factor. A total of 2400 patients were studied in two groups (1200 in each group). The mean (range) age of the patients was 28.40 (18-44) years. Five patients (0.41%) in the lidocaine group and seven (0.58%) in the articaine group had NSD after injection (p = 0.77). The prevalence of NSD after IANB was no higher in the articaine group than in the lidocaine group.

Optimization and comparison of unidirectional lidocaine-loaded buccal patch with the articaine-loaded buccal patch to reduce injection pain and increment of patients' compliance in dental procedures: A double-blind randomized controlled trial. Heliyon 2024; 10:e35533. [PMID: 39211919 PMCID: PMC11357764 DOI: 10.1016/j.heliyon.2024.e35533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 07/25/2024] [Accepted: 07/30/2024] [Indexed: 09/04/2024] Open
Abstract
Introduction Nervous patients often postpone dental visits until they are in severe pain, exacerbating anxiety. Buccal patches provide a noninvasive method of delivering drugs between the upper gum and cheek, offering local and systemic effects. Prior research has demonstrated the effectiveness, safety, and reliability of topical lidocaine or articaine patches for oral anesthesia. Consequently, this study aimed to develop a three-layered buccal drug delivery system for topical anesthetics. Methods The first step was preparing and optimizing lidocaine-loaded three-layer patches using Design-expert software. The effects of ethylcellulose, Eudragit, and carbopol concentrations were investigated on patch characteristics, including mucoadhesion, Young's modulus, and Elongation-at-break. Subsequently, patches were fabricated according to the optimized formulation determined by the software, and their efficacy was studied in a randomized, double-blind clinical trial. Participants received either lidocaine or articaine-loaded compared with placebo in a split-mouth study. They evaluated their pain levels using the Visual Analogue Scale (VAS), and the onset and duration of action were recorded for each treatment. Results According to the results, increasing ethyl cellulose and Eudragit concentrations improved mucoadhesion force (p < 0.05) while increasing ethyl cellulose and reducing Eudragit concentrations increased Young's modulus (p < 0.05). Increasing Carbopol and decreasing Eudragit concentrations also raised elongation at break significantly in the patch (p < 0.05). Treatment with lidocaine-loaded patches resulted in lower VAS scores and faster onset of action in patients than articaine-loaded patches. However, the duration of the effect was longer in the former(p < 0.001). Conclusion Based on the responses' analysis, the formulation of the 3-layered buccal patch was optimized. This formulation comprised 4.72 % ethyl cellulose, 2 % Carbopol, and 5 % eudragit. Clinical evaluation results showed that loading the optimized formulation with lidocaine was more efficient in controlling the injection pain than articaine. Trial registration This trial was prospectively registered with irct.behdasht.gov.ir (registration number: IRCT20210118050067N2) on Aug 19, 2022.

Abstract
Effective pain management is crucial for the successful performance of various endodontic procedures. Painless treatments are made possible by anesthetizing the tooth to be treated using various nerve-block techniques. However, certain circumstances necessitate supplemental anesthetic techniques to achieve profound anesthesia, especially in situations involving a "hot tooth" in which intrapulpal anesthesia (IPA) is employed. IPA is a technique that involves the injection of an anesthetic solution directly into the pulp tissue and is often utilized as the last resort when all other anesthetic techniques have been unsuccessful in achieving complete pulpal anesthesia. This review focuses on the IPA procedure and the factors that influence its success. Additionally, the advantages, limitations, disadvantages, and future directions of IPA are discussed.

Abstract
Background To investigate the comparative effects of local anesthesia using lidocaine with adrenaline vs. articaine with adrenaline in endoscopic endonasal dacryocystorhinostomy (EN-DCR). Methods This retrospective study included a total of 180 patients. These patients were categorized into two groups: the lidocaine group, which received 2% lidocaine (1:100,000 adrenaline), and the articaine group, which received 4% articaine (1:100,000 adrenaline) for local anesthesia. The study compared anesthesia efficacy, intraoperative pain levels, intraoperative bleeding, as well as differences in heart rate and blood pressure between the two groups. Results The articaine group demonstrated a significantly lower visual analog scale (VAS) pain score when compared to the lidocaine group, measuring at 4.4 ± 0.6 cm vs. 5.0 ± 1.0 cm, respectively (P < 0.0001). Additionally, the articaine group exhibited a higher anesthesia efficacy compared to the lidocaine group (89.0% vs. 76.6%, p = 0.0487). Notably, the articaine group experienced less nasal mucosal bleeding during the surgery in contrast to the lidocaine group (p = 0.004). However, there were no statistically significant differences in changes in blood pressure and heart rate between the two groups (p > 0.05). Conclusion This study demonstrated that 4% articaine (1:100,000 adrenaline) has superior clinical effectiveness in comparison to 2% lidocaine (1:100,000 adrenaline) in EN-DCR.

Abstract
Introduction Oxidative stress, an imbalance between reactive oxygen species (ROS) production and antioxidant defenses, plays an important role in various dental diseases. Local anesthetics are frequently used in dentistry. The potential antioxidant activity of dental local anesthetics can contribute to dental practice. Therefore, this study aimed to investigate the ROS-scavenging activities of three commonly used dental local anesthetics, lidocaine, prilocaine, and articaine, focusing on their effects on hydroxyl radicals (HO•) and superoxide anions (O2 •-). Materials and methods The electron spin resonance (ESR) spin-trapping technique was employed to specifically measure the ROS-scavenging activities of these local anesthetics at varying concentrations. Results Lidocaine, prilocaine, and articaine exhibited concentration-dependent HO•-scavenging activities, with IC50 values of 0.029%, 0.019%, and 0.014%, respectively. Lidocaine and prilocaine showed concentration-dependent O2 •--scavenging activity, with IC50 values of 0.033% and 0.057%, respectively. However, articaine did not scavenge O2 •-. Conclusions The proactive use of dental local anesthetics may mitigate oxidative injury and inflammatory damage through direct ROS scavenging. However, further research is needed to elucidate the specific mechanisms underlying the antioxidant effects of these dental local anesthetics and their potential impact on the dental diseases associated with oxidative stress.

Abstract
Pain mitigation strategies for disbudding in goat kids have gained significant attention in recent years because of growing concerns for animal welfare. Disbudding, the removal of horn buds in young goats, is a common practice to enhance safety and manage herd dynamics. However, the procedure will cause pain and distress if not managed effectively. This review covers the array of pain mitigation techniques currently available for disbudding, including the efficacy of these strategies in reducing pain and stress during the disbudding process, with specific attention to the potential toxicity associated with local anesthetics. The current best practice for disbudding on the farm suggests sedation/analgesia with an alpha-2 agonist, the placement of a two-point cornual nerve block, and then an NSAID for postoperative pain. In conclusion, this review offers recommendations for future research directions aimed at enhancing the welfare of young goats subjected to the disbudding procedure. These suggestions hold the promise of fostering significant improvements in the overall well-being of these animals.

Abstract
Background Although most of the metabolism of local anesthetics (LAs) takes place in the liver, no study has investigated the effect of these anesthetics on the kidney function of single-kidney humans or animals. The present study was conducted to examine the effect of LAs on renal function in single-kidney rats. Materials and Methods The present experimental animal study with two control groups was done in an animal laboratory. Forty-two rats were randomly assigned to seven groups of six rats, including two control groups and five experimental groups. The experimental groups underwent intraperitoneal anesthesia with 2% lidocaine, 2% lidocaine with 1:80,000 epinephrine, 4% articaine, 3% prilocaine with 0.03 IU Felypressin, and 3% mepivacaine, respectively. Unilateral nephrectomy was done. After 24 h, the rats' blood urea nitrogen (BUN), serum creatinine (Cr), and blood specific gravity (BSG) were measured. A standard dose of anesthetics was injected into the peritoneum for 4 days afterward. Then, these indices were measured again 24 h after the last injection. Data were analyzed using IBM SPSS (version 21.0). One-way analysis of variance, Tukey's honestly significant difference post hoc, and paired t-tests were used for statistical analysis. P < 0.05 was considered statistically significant. Results The results indicated significant differences among groups in the rats' BUN and serum Cr 24 h after nephrectomy (P < 0.05). However, there were no significant differences in BUN, BSG, and Cr among groups after the interventions. Conclusion LAs did not affect renal function in single-kidney rats. Therefore, dentists can use the anesthetics in single-kidney people.

Abstract
This systematic review evaluates the efficacy of single buccal infiltration of articaine for extracting upper teeth. A search of the PubMed, Ovid SP, Scopus, Embase, and Cochrane databases for English-language studies published between 2000 and 2021 was performed on August 26, 2022, based on the pre-specified question using the MeSH terms [(buccal) and (articaine) and (infiltration) and (dental)]. Of the 16 clinical trials identified involving 1,339 patients, six compared the subjective procedural pain associated with single buccal infiltration of articaine with that of lidocaine, three of which reported reduced pain and the other three greater success in extraction for the articaine group. Four of the 16 studies compared the procedural pain associated with single buccal infiltration of 4% articaine with double (buccal and palatal/lingual) infiltration; two reported insignificant differences between the groups; and the other two reported greater success using buccal and palatal injections. Five of the 16 studies compared the procedural pain associated with single buccal articaine with double buccal and palatal/lingual infiltration of 2% lidocaine and reported insignificant differences. The other of the 16 studies compared the subjective pain associated with single buccal infiltration of 4% articaine 1:100:000 with single buccal infiltration of 4% articaine 1:200:000 and found a statistically significant difference. All of these studies concluded that upper permanent maxillary teeth can be extracted using only a 4% articaine buccal infiltration, but further investigation is necessary to determine whether this approach can replace the gold standard of buccal and palatal infiltration.

Abstract
Spinal anesthesia is a safe alternative to general anesthesia but remains underrepresented in the ambulatory setting. Most concerns relate to low flexibility of spinal anesthesia duration and the management of urinary retention in the outpatient setting. This review focuses on the characterization and safety of the local anesthetics that are available to adapt spinal anesthesia very flexibly to the needs of ambulatory surgery. Furthermore, recent studies on the management of postoperative urinary retention provide evidence for safe, but report wider discharge criteria and much lower hospital admission rates. With the local anesthetics that have current approval for usage in spinal anesthesia, most requirements for ambulatory surgeries can be met. The reported evidence on local anesthetics without approval supports clinically established off-label use and can improve the results even further.

Abstract
Local anesthetics occupy a prime position in clinical medicine as they temporarily relieve the pain by blocking the voltage-gated sodium channels. However, limited structural diversity, problems with the efficiency of syntheses and increasing toxicity, mean that alternative scaffolds with improved chemical syntheses are urgently needed. Here, we demonstrate an MCR-based approach both towards the synthesis of commercial local anesthetics and towards novel derivatives as potential anesthesia candidates via scaffold hopping. The reactions are efficient and scalable and several single-crystal structures have been obtained. In addition, our methodology has been applied to the synthesis of the antianginal drug ranolazine, via an Ugi three-component reaction. Representative derivatives from our libraries were evaluated as neuronal activity inhibitors using local field potential recordings (LFPs) in mouse hippocampal brain slices and showed very promising results. This study highlights new opportunities in drug discovery targeting local anesthetics.

Abstract
Objectives The purpose of this systematic review was to evaluate if articaine has better efficacy as compared to lignocaine when used for infiltration anaesthesia for primary molar extractions. Methods The electronic databases of PubMed, Embase, Scopus, BioMed Central, CENTRAL, and Google Scholar were searched up to August 2020. Randomized controlled trials on paediatric patients comparing the infiltration of articaine with lignocaine for extraction of primary molar were included. Pain of extraction and successful palatal/lingual anaesthesia with single buccal infiltration was evaluated. Results Six studies were included. We found no difference in pain scores when comparing singular buccal infiltrations of articaine and lignocaine for primary molar extractions. A meta-analysis of extraction pain scores from three studies indicated no statistically significant difference between buccal infiltration of articaine vs combined buccal and palatal/lingual infiltration of lignocaine. Comparing buccal with palatal/lingual infiltration of both articaine and lignocaine with data from three studies, articaine was found to significantly reduce pain scores. Conclusion Our review encompassing a limited number of studies suggests that single buccal infiltration of articaine may have a role in primary molar extractions. Articaine may have a better anaesthetic effect compared to lignocaine but the difference may not be clinically relevant.

Abstract
Myotonic dystrophy (dystrophia myotonica; DM) is an uncommon progressive hereditary muscle disorder that can present with variable severity at birth, in early childhood, or most commonly as an adult. Patients with DM, especially type 1 (DM1), are extremely sensitive to the respiratory depressant effects of sedative-hypnotics, anxiolytics, and opioid agonists. This case report describes a 37-year-old male patient with previously undiagnosed DM1 who received dental care under minimal sedation using intravenous midazolam. During the case, the patient experienced 2 brief episodes of hypoxemia, the second of which required emergency intubation after propofol and succinylcholine and resulted in extended hospital admission. A lipid emulsion (Liposyn II 20%) infusion was given approximately 2 hours after the last local anesthetic injection due to slight ST elevation and suspicion of local anesthetic toxicity (LAST). Months after treatment, the patient suffered a fall resulting in a fatal traumatic brain injury. Complications noted in this case report were primarily attributed to the unknown diagnosis of DM1, although additional precipitating factors were likely present. This report also provides a basic review of the literature and clinical guidelines for managing myotonic dystrophy patients for dental care with local anesthesia, sedation, or general anesthesia.

Abstract
OBJECTIVE We purposed to compare the effects of certain local anesthetic applications on pain and hemorrhage caused by nasal pack removal. METHODS Design: Prospective, placebo-controlled study. Setting: Ataturk University Medical Faculty Hospital. This study was done in 90 patients who applied nasal packing after septoplasty. All patients were divided randomly into four groups. Each group was applied 2% lidocaine, 2% tetracaine, 4% articaine or 0.9% sodium chloride (NaCl) into their Merocel packs 15 min before removing. Verbal analog scale (VAS) score was registered from all patients, and the amount of hemorrhage was noted during the removal of the nasal packs and then for 30 min. RESULTS The study groups had significantly better pain scores than the control group during nasal pack removal and after 5 min (p<0.001). The articaine and the lidocaine groups had also better pain scores than the control group at 15th min after the removal of the nasal packs (p<0.05), but the tetracaine group had no better pain scores than the control group, which is statistically significant at p>0.05. Analysis of bleeding scores after the removal of packs showed that the articaine and the lidocaine groups had better bleeding scores than the control group (p<0.004 and p<0.033, respectively). CONCLUSION Topical articaine application into nasal packs just before removing in the patients who underwent septoplasty can be safely used for less pain, less hemorrhage, and more patient tolerance.

Abstract
Background It is unclear if buccal articaine infiltration can be used as an alternative to standard inferior alveolar nerve block (IANB) for treating mandibular molars in pediatric patients. Therefore, this study aimed to pool evidence to compare the efficacy of buccal infiltration of articaine vs IANB with lignocaine for pediatric dental procedures. Material and Methods We searched the PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases for randomized controlled trials (RCTs) comparing the two techniques in pediatric patients and reporting the success of anesthesia and/or pain during treatment. PRISMA guidelines were followed. Results Seven RCTs were included. Pooled analysis of five studies indicated no statistically significant difference in the success rates of the two anesthetic techniques (OR: 1.02; 95% CI: 0.13, 7.96; I2=69%, p=0.98). Meta-analysis of data from the four studies demonstrated no statistically significant difference in pain during the procedure with buccal infiltration of articaine or IANB with lignocaine (SMD: 0.62; 95% CI: -1.37, 0.12; I2=88%, p=0.10). Conclusions Evidence suggests that buccal infiltration of articaine is a viable alternative to IANB with lignocaine in pediatric patients for treating mandibular molars. Based on the confidence intervals, there may be a tendency of higher success rates with buccal infiltration of articaine. Key words:Lignocaine, articaine, primary dentition, children, molars.

Abstract
The article is a review of modern literature and an analysis of the legal framework regarding the use of local anesthetics in children under 4 years of age. There is a discussion of the validity of the off-label principle. In the domestic and foreign literature, there are publications highlighting the use of drugs based on 4% articaine in children under 4 years old, despite age-related contraindications according to the instructions. It is necessary to pay special attention to the regulatory status of the instructions for the medical use of the medicinal product. Summarizing the presented arguments, we can talk about the available spectrum of clinical studies, meta-analyzes and RCT data on the use of articaine in dental practice in children under 4 years of age, which indicates its effectiveness and is considered a safe alternative to lidocaine for use. in children of all ages.

Abstract
Introduction The substitution of reference drugs for similar, new or existing drugs in the market is a dilemma present in daily dental procedures. In order to decide whether or not to adopt a new drug in relation to the reference, a clinical trial can provide the necessary evidence. Methods A total of 179 healthy volunteers (18-25 years) requiring extraction of mandibular third molars completed the study. Subjects were randomized into 4 groups: right, left, Arteek-SP and Septanest. Allocations consisted of 4% Articaine hydrochloride with 1:10000 epinephrine. The primary aim of this randomized controlled trial was to determine whether the test drug Arteek-SP was noninferior by a margin of 10% in the proportion of patients with total absence of pain, compared to the reference drug Septanest in the extraction of mandibular third molars using inferior alveolar nerve blocks. Secondary outcomes included, hemodynamic parameters, volume (mL), pain scores assessed during one visit and reported postoperative discomfort assessed during 8 days. Noninferiority was declared if total absence of pain for both groups was equal to 0.9, with a significance level of 5% (P < 0.05) and power at 90% (β = 0.1) at 95% confidence level. Results Arteek-SP was applied during the first surgery to 90 volunteers (50.28%) and Septanest was applied to 89 subjects (49.72%). Less than 10% difference was identified, in the proportion of patients with total absence of tooth pain P < 0.05 and in the gum P < 0.1, at 95% CI, when Arteek-SP was applied first in comparison with Septanest, establishing noninferiority. Conclusion The clinical performance of the test drug Arteek-SP is noninferior to the reference drug Septanest. They can be considered interchangeable in terms of cost or convenience. Registration ClinicalTrials.org, number NCT4166890.

Abstract
The aim of this study was to analyze the use of dental local anesthetics in Germany compared with international data. The type and distribution of dental local anesthetics and added vasoconstrictors based on a representative sample of German dentists itemized over a period of 7 years (2011 to 2017) were evaluated and statistically analyzed. The results were compared with international dental local anesthetic consumption data published since 2005. With a consistent market share of nearly 98%, articaine was the first-line local dental anesthetic agent in Germany. During the investigation period, German dental local anesthetics with epinephrine 1:200,000 had ∼50% market shares, whereas formulations with epinephrine 1:100,000 had 40% to 45% market shares. Articaine, with market shares between 38% and 81%, was also the preferred anesthetic agent in various other countries, with the notable exceptions of the United Kingdom and the United States, where lidocaine was the preferred local anesthetic agent. Epinephrine was the preferred vasoconstrictor internationally, similar to Germany. The larger market share of higher concentrated epinephrine 1:100,000 was remarkable, considering the increasing number of medically compromised patients. Increased consideration for using agents with reduced dosages of epinephrine (1:200,000) is generally recommended.

Abstract
OBJECTIVE To investigate the pharmacokinetics, efficacy and convulsive dose of articaine hydrochloride in goat kids. STUDY DESIGN Experimental prospective study. ANIMALS A total of 18 (n = 6 animals per experiment) male Saanen goat kids (2-4 weeks old). METHODS The study consisted of three experiments. The first determined the pharmacokinetics of articaine following intravenous administration of articaine hydrochloride (8 mg kg-1). The second experiment investigated the anaesthetic efficacy and pharmacokinetics following cornual nerve block using 1.5% articaine hydrochloride. Anaesthesia of horn buds was evaluated using the response to pinprick test. Non-compartmental analysis was used. The final experiment determined the convulsive dose of articaine and its corresponding plasma concentration following intravenous infusion of articaine hydrochloride (4 mg kg-1 minute-1). Data are shown as mean ± standard deviation. RESULTS The mean terminal half-life (t1/2λz), mean volume of distribution at steady state (Vdss) and mean plasma clearance (CL) of articaine following intravenous administration were 0.66 hour, 3.81 L kg-1 and 5.33 L hour-1 kg-1, respectively. After cornual nerve block, the mean maximum plasma concentration of articaine was 587 ng mL-1 at 0.22 hour and its mean t1/2λz was 1.26 hours. Anaesthesia of horn buds was observed within 4 minutes following cornual nerve block. The mean dose required to produce convulsions was 16.24 mg kg-1 and mean convulsive plasma concentrations of articaine and articainic acid were 9905 and 1517 ng mL-1, respectively. CONCLUSIONS Intravenous administration of 8 mg kg-1 of articaine hydrochloride did not cause any adverse effects. Pharmacokinetic data suggest that articaine was rapidly eliminated and cleared. Cornual nerve block using 1.5% articaine hydrochloride alleviated the response to the acute nociceptive stimulus during disbudding. CLINICAL RELEVANCE Articaine hydrochloride appears to be a safe and effective local anaesthetic for disbudding in goat kids.

Abstract
Simple Summary Red deer (Cervus elaphus) are farmed in New Zealand for the production of velvet antler. Velvet is harvested as living antler tissue, and currently lignocaine is the only licensed local anaesthetic approved for deer antler removal in New Zealand. The use of lignocaine is not without consequences, including drug residues in harvested velvet antler tissue and its short acting analgesic effect. This study was designed to determine the effect of local anaesthetic, articaine hydrochloride as an alternative treatment and to establish the baseline measurements of mechanical nociceptive threshold in 40 male yearling red deer. Ten of the forty enrolled deer were selected for the articaine efficacy study. The mechanical nociceptive thresholds were measured using a handheld algometer applied at 4 points; the cranial, medial, caudal and lateral aspects of the base of each antler. The force applied, which resulted in a movement by the animal, was recorded in newtons (N). This study showed that nociceptive threshold response in deer could be reliably measured, and articaine proved to be a promising alternative for velveting the deer antlers. Abstract New Zealand deer farming centres on the production of meat and velvet antler. Velvet antler removal is a painful procedure and currently, New Zealand Animal Welfare regulations dictate surgical removal of velvet antlers under lignocaine anaesthesia. To improve our knowledge on the efficacy and duration of other local anaesthetics to mitigate pain after antler removal, it is important to accurately assess and quantify pain arising from antler removal. Therefore, the current study was designed to validate mechanical nociceptive threshold (MNT) testing using a Wagner hand-held algometer, and to apply this methodology to assess the efficacy and duration of action of articaine for antler removal in deer. Baseline force (N) required to elicit the nociceptive response was recorded in 40 yearling male red deer on three alternate days. Ten of the 40 animals were selected for antler removal after administration of 4% articaine hydrochloride as a ring block. The duration of analgesic efficacy of articaine was assessed by algometry across 5 time points. There was a significant difference in MNTs among the three days (day 3 versus day 1 (p < 0.0001), day 2 versus day 1 (p < 0.0001), and day 1 versus day 2 (p < 0.01)). Positive correlations were observed between weight, antler length and thresholds. The MNT values remained above 20N for 6 h after removal of velvet antlers under the articaine ring block. This study provides valuable information about the use of MNT in red deer. These findings lay a foundation for future studies in the topics of peri-operative and postoperative pain management in deer antler removal, and a possible alternative use for articaine.

Abstract
Background Lidocaine is the gold standard local anesthetic (LA) for UK pediatric dental treatment. Recent reports suggest frequent Articaine use in Europe and Canada, with evidence indicating more profound anesthesia. The aim of this study was to examine pediatric dentistry specialist experiences and practices relating to Articaine administration in the UK. Methods A literature review was followed by a survey using an anonymous 15-item electronic questionnaire, which was sent to 200 registered British Society of Pediatric Dentistry (BSPD) specialists. Descriptive analyses, Z score, chi-squared test, Fisher's exact test, and Spearman's correlation test were performed. Results Sixty-one (30.5%) participants responded, and 12 (19.7%) indicated Articaine as their first line anesthetic. Articaine was used daily or weekly by 38 (62.3%) respondents, depending on the clinical context. Articaine was commonly used to avoid inferior alveolar nerve blocks and gain more profound anesthesia in abscessed or hypomineralized teeth. Participants reported significantly more adverse effects with lidocaine (Fisher's exact test, P < 0.0001) than with Articaine. Articaine was most often administered in children aged > 4 years via infiltration techniques. Only 15 (24.6%) respondents reported awareness of guidelines for Articaine use in pediatric patients. Conclusions Articaine use in pediatric dentistry is common; however, evidence supporting its practice is limited. Several specialists follow conventions based on anecdotal evidence. Formulating guidance to aid decision-making when treating pediatric patients under LA would be beneficial.

Abstract
Over the past century, there is perhaps no greater contribution to the practice of clinical dentistry than the development and application of local anaesthesia. What were once considered painful procedures have now been made routine by the deposition and action of local anaesthetics. This article will serve as a review of basic pharmacological principles of local anaesthesia, subsequent sequelae that can arise from their use, considerations when using local anaesthetics, and recent advances in the delivery of local anaesthetics.

Abstract
Purpose The purpose of the study was to evaluate and compare the efficacy of buccal and lingual infiltration (B/L I) of 2% lignocaine HCl and buccal infiltration (BI) of 4% articaine for orthodontic extraction of mandibular premolars. Materials and Method One hundred and four patients (age group 14-26 years) were selected with the indication of bilateral mandibular first or second premolar extraction for orthodontic treatment. Patients were randomly distributed in 2 groups. Group A received B/L I with lignocaine and Group B for BI with articaine in two different appointments in 2-week interval. The pain scores for each patient were evaluated during extraction using the visual analogue scale (VAS) and verbal pain scale (VPS). Statistical analysis was performed by descriptive and inferential statistics using Chi-square test. The agreement between VAS and VPS was obtained by applying intra-class correlation coefficient. Results No pain was experienced during extraction in 77% (VAS) and 79% (VPS) patients infiltrated in group A and 84% (VAS) and 90% (VPS) patients of group B with articaine. The difference between the groups was statistically significant. A strong positive correlation was found between VAS and VPS scores in the both groups. Conclusion Buccal infiltration with articaine proved to be an effective alternative to buccal and lingual infiltration with lignocaine in the extraction of mandibular premolars.

Abstract
A predictive computational study was conducted in order to assess the efficiency of electrocyclization reactions of keteniminium salts, in an effort to form a variety of heterocyclic systems, namely, 3-amino(benzo)thiophenes, 3-amino(benzo)furans, 3-aminopyrroles, as well as 3-aminoindoles. A density functional theory (DFT) approach was utilized and the effect of heteroatoms (NMe, O, S) was thoroughly investigated by means of population analysis, QTAIM, NICS, ACID, and local reactivity descriptors (Parr and Fukui functions). The electrocyclization of enamines leading to 3-aminopyrroles was shown to be both kinetically and thermodynamically most favorable. Moreover, the pericyclic nature of the electrocyclizations was confirmed using FMO, QTAIM, NICS, and ACID methods. Additionally, substituent effects were investigated in order to give further insight on the reactivity of heteroatom containing keteniminium systems toward electrocyclization reactions. Finally, computational predictions were experimentally confirmed for a selection of keteniminium systems.

Abstract
The local anesthetics lidocaine and articaine are among the most widely used drugs in the dentist's arsenal, relieving pain by blocking voltage-dependent Na+ channels and thus preventing transmission of the pain signal. Given reports of infrequent but prolonged paresthesias with 4% articaine, we compared its neurotoxicity and functional impairment by screening cultured neural SH-SY5Y cells with formulations used in patients (2% lidocaine + 1:100,000 epinephrine or 4% articaine + 1:100,000 epinephrine) and with pure formulations of the drugs. Voltage-dependent sodium channels Na(v)1.2 and Na(v)1.7 were expressed in SH-SY5Y cells. To test the effects on viability, cells were exposed to drugs for 5 minutes, and after washing, cells were treated with the ratiometric Live/Dead assay. Articaine had no effect on the survival of SH-SY5Y cells, while lidocaine produced a significant reduction only when used as pure powder. To determine reversibility of blockage, wells were exposed to drugs for 5 minutes and returned for medium for 30 minutes, and the calcium elevation induced by depolarizing cells with a high-potassium solution was measured using the calcium indicator Fura-2. High potassium raised calcium in control SH-SY5Y cells and those treated with articaine, but lidocaine treatment significantly reduced the response. In conclusion, articaine does not damage neural cells more than lidocaine in this in vitro model. While this does not question the safety of lidocaine used clinically, it does suggest that articaine is no more neurotoxic, at least in the in vitro setting.

Abstract
OBJECTIVE Articaine entered clinical use in 1976; however, evidence basis for articaine's reputation is not entirely clear. The aim of the study is to compare and analyze 4% articaine with 1:100,000 epinephrine and 2% lignocaine with 1:100,000 epinephrine in patients operated for mandibular third molar impaction with respect to efficacy and safety, time of onset and duration of anesthesia and duration of postoperative analgesia. METHODS The study was done on fifty patients requiring surgical extraction of mandibular third molar; randomly divided into two groups of 25 each, receiving 4% articaine hydrochloride with 1:100,000 epinephrine and 2% lignocaine hydrochloride with 1:100,000 epinephrine. Difficulty index for extraction, volume, onset and duration of anesthesia and duration of postoperative analgesia were recorded. Pain was assessed using Heft-Parker VAS. The data were analyzed using appropriate statistical analysis. RESULTS The mean onset time for articaine and lignocaine is 3.16 ± 0.55 and 3.2 ± 0.48 min, respectively. Articaine group experienced statistically significant longer period of analgesia and duration of action 289.04 ± 40 and 361.88 ± 40 min, respectively, as compared to lignocaine which is 144.2 ± 12 and 197.44 ± 25 min, respectively. No statistical difference between the two groups with regard to pain experience. CONCLUSION 4% Articaine is more potent and has longer duration of action with better postoperative analgesia and could be considered as an alternative to lignocaine in clinical practice. With management of postoperative pain being the critical component of patient care, clinical trials are required to develop long acting local anesthetic with increased postoperative analgesia effect.

Abstract
AIMS To investigate the analgesic efficacy of articaine hydrochloride for antler removal in red deer (Cervus elaphus) following S/C administration as a ring block, and to quantify the residue concentrations of articaine compared to lignocaine in the harvested antlers. METHODS Articaine hydrochloride (40 mg/mL) was administered to 10 male red deer as a ring block around the base of each antler at 1 mL/cm of pedicle circumference. Analgesia was evaluated by determining the response to a saw cut test every 1-minute, until no response was observed. Behaviour during and following removal of antlers was also recorded. Twenty commercially harvested velvet antlers were also collected following S/C administration of 2% lignocaine hydrochloride. A liquid chromatography-mass spectrometry (LC-MS) method for quantification of residues of articaine and lignocaine in velvet antlers was developed and validated. RESULTS In red deer administered 4% articaine hydrochloride as a ring block, the median interval to analgesia was 4 (min 3, max 5) minutes and no deer showed withdrawal responses during antler removal. There were no signs of toxicity or adverse effects up to 2 hours after administration. The sample preparation method developed for the LC-MS was simple and had acceptable extraction recoveries of articaine and lignocaine from the velvet antlers. The lower limits of quantification of lignocaine and articaine were 5 and 50 ng/g, respectively. Mean concentrations of articaine in antlers following ring block with 4% articaine hydrochloride were 1.50 (SD 1.09) mg/kg, and of lignocaine following ring block with 2% lignocaine hydrochloride were 0.66 (SD 0.71) mg/kg. CONCLUSIONS AND CLINICAL RELEVANCE A ring block with 4% articaine hydrochloride at a dose of 1 mL/cm of pedicle circumference provided effective analgesia for velvet antler removal in red deer. The LC-MS method developed and validated to quantify articaine and lignocaine was simple and sensitive. Based on these results, articaine hydrochloride appears to be an effective alternative to lignocaine hydrochloride for velvet antler removal. However, further studies to evaluate the safety and residue concentrations of articaine and articainic acid are required before it can be recommended for use in deer.Abbreviations: DMA: 2,6-dimethylaniline; LC-MS: Liquid chromatography-mass spectrometry; MEGX: Monoethylglycinexylidide; MRL: Maximum residue level.

Abstract
Objectives Articaine is a rapid-onset, short-duration, local anesthetic. The aim of this study was to study the effect of adding tramadol to articaine in an axillary block to prolong the analgesic effect. Methods This study was conducted with 60 patients of American Association of Anesthesiologists classification I or II and aged 18 to 60 years who underwent hand or forearm surgery with an axillary plexus block using a nerve stimulation technique. The patients were randomized into 2 groups: Group A (n=30) received 40 mL 1% articaine and Group AT (n=30) was administered 40 mL 1% articaine with 100 mg tramadol. The onset of sensory block, motor block, duration of sensorial block and motor block, duration of analgesia and hemodynamic parameters were recorded before the block and 5, 10, 20, 30, 60, 120, 180 minutes after the local anesthetic injection. Results The sensory block duration in Group AT (187.5±13.0 min) was significantly longer than that of group A (140.78±8.74 min) (p<0.02). The motor block duration in Group AT (137.4±3 min) was significantly longer than that seen in Group A (93.71±9.6 min) (p<0.01). The duration of analgesia was longer in Group AT (218.8±18.2 min) than in Group A (170.8±17.2 min) (p<0.05). In group AT, 2 patients experienced the side effect of nausea and 1 patient had hypotension in the postoperative period. Conclusion This study demonstrated that the addition of 100 mg of tramadol to articaine used for an axillary plexus block prolonged analgesia.

Abstract
The aim of this study was to compare the efficacy of articaine versus lidocaine, both containing epinephrine, using a single buccal infiltration for extraction of primary molars.A total of 100 children requiring primary molar extraction received buccal infiltration using either 4% articaine or 2% lidocaine, both with epinephrine, with 50 children in each group. The Wong-Baker Facial Pain Scale (FPS) was used to evaluate pain perception subjectively. The heart rate and the blood pressure values were assessed objectively as an indirect measure of physiological pain perception. The Wilcoxon-Mann-Whitney test was used for comparing mean pain scores, heart rate, and blood pressure in both the groups. Single buccal infiltration with articaine was sufficient for achieving palatal or lingual anesthesia in all the children receiving it while all children in the lidocaine group required supplemental anesthesia. The mean FPS value was found to be higher in lidocaine group and was statistically significant. The mean heart rate recorded during the intervention was less than the mean baseline values in the articaine group, which was found to be statistically significant. For pediatric patients age 7 to 12 years, single buccal infiltration with 4% articaine with 1:100,000 epinephrine is more effective compared to 2% lidocaine with 1:80,000 epinephrine for primarly molar extraction.

Abstract
OBJECTIVE We purposed to compare the effects of certain local anesthetics soaked Merocel nasal packs on hemorrhage and pain after septoplasty. MATERIALS AND METHODS This study is a prospective double-blind study that was done in patients undergoing septoplasty. The study was created with 90 patients. All patients were divided into four groups. The each group was applied 2% lidocaine plus adrenaline, 2% tetracaine, 4% articaine plus adrenaline as study groups or 0.9% sodium chloride (NaCl) as control group in their Merocel packs after septoplasty. Verbal analog scale (VAS) was applied to all patients and the amount of postoperative hemorrhage was noted during postoperative period. The statistical analysis was performed using Student's t test and Chi-square test on each patient group at each time point. RESULTS The study groups (2% lidocaine plus adrenaline, 2% tetracaine and 4% articaine plus adrenaline groups) had significantly better pain scores versus control group in the 1st, 4th, 8th, 16th and 24th postoperative hours (p < 0.05). The articaine plus adrenaline group had better pain scores than the lidocaine plus adrenaline group, and the lidocaine plus adrenaline group had better pain scores than the tetracaine group in the postoperative first day. Also articaine plus adrenaline group had less postoperative bleeding rate than the lidocaine plus adrenaline, tetracaine and control groups (p < 0.05). There was no statistically significant difference between the lidocaine plus adrenaline, tetracaine and control groups in terms of postoperative hemorrhage (p > 0.05). CONCLUSION Topical articaine plus adrenaline application in the nasal packs can be safely used for less pain and bleeding following septoplasty.

Abstract
OBJECTIVES To investigate the potency and speed of action of 4% articaine and 2% mepivacaine for maxillary teeth extractions. MATERIAL AND METHODS Ninety-four patients, aged between 16 to 70 years old, were recruited in this study. Two regimens were randomly administered over one visit. Patients of treatment group 1 received mepivacaine 2% with 1:100,000 adrenaline, whereas treatment group 2 - articaine 4% with 1:100,000 adrenaline. The onset time of pulp anaesthesia for maxillary teeth indicated for extraction was determined by electronic pulp testing. At any point of trial (10 minutes), the anesthetized tooth becomes unresponsive for maximal pulp stimulation (64 reading), the extraction was carried out. RESULTS In this study, 85 patients had successful local anaesthetic followed by extraction within the study duration time (10 min). However, 5 patients had failed dental extraction (4 in mepivacaine group and 1 in articaine group). Patients in the articaine buccal infiltration group recorded faster onset time of action regarding anaesthesia and teeth extraction than patients in mepivacaine buccal infiltration group (P = 0.03). CONCLUSIONS Articaine is an effective anaesthetic with a rapid onset, comparable to mepivacaine in infiltrative techniques used for maxillary teeth extraction. However, articaine has clinically achieved faster dental anaesthesia and earlier teeth extraction than mepivacaine. So, articaine can be the local anaesthetic of first choice in oral surgery.

Abstract
In order to compare the efficacy of lidocaine and articaine for pain control during third molar surgery, 160 patients presenting bilateral asymptomatic impacted mandibular third molars were selected. They received 1.8 mL of 2% lidocaine with epinephrine 1:100,000 during inferior alveolar nerve block. In group 1 (n = 80), an infiltrative injection of 0.9 mL of 2% lidocaine with epinephrine 1:100,000 was performed in buccal-distal mucosa of the third molar. Group 2 (n = 80) received 0.9 mL of 4% articaine with epinephrine 1:100,000 in the contralateral side. All procedures were performed at the same visit, by a single operator, in a double-blind and parallel design. The duration of each surgery and the moment when the patient expressed pain were noted. Data were analyzed by nonpaired t test and chi-square test (alpha = 5%). Duration of surgery did not differ (p = .83) between Groups 1 (19.8 ± 2.3 minutes) and 2 (19.7 ± 3.0 minutes). Pain was expressed more in group 1 (26.3%) than in group 2 (10%) (odds ratio = 3.2, p = .0138). In both groups, tooth sectioning was the most painful event (p < .0001). No influence of gender (p = .85) or age (p = .96) was observed in pain response. Buccal infiltration of 4% articaine with epinephrine 1:100,000 showed more efficacy than 2% lidocaine with epinephrine 1:100,000 when used in combination with inferior alveolar nerve block in controlling intraoperative pain related to impacted mandibular third molar surgery.

Abstract
HINTERGRUND Anders als Erwachsene benötigen Kinder bei dermatochirurgischen Eingriffen besondere Aufmerksamkeit; die Anwendung verschiedener Analgetika, Anästhetika oder Sedativa erfordert eine gründliche Kenntnis von Pharmakokinetik und -dynamik der Medikamente. Außerdem können Medikamente zur Sedierung/Allgemeinanästhesie bei operierten Kindern zu Anästhesie- oder Analgesie-bedingten Komplikationen einschließlich Störungen der geistigen Entwicklung führen. ZIEL: Auf Basis unserer klinischen Erfahrung und einer Literaturübersicht stellen wir die gängigsten in der pädiatrischen Dermatochirurgie verwendeten Analgetika, Anästhetika und Sedativa dar und diskutieren Risiken und Komplikationen nach dermatochirurgischen Eingriffen. ERGEBNISSE Topische Anästhetika können bei Kindern für oberflächliche dermatologische Eingriffe oder vor einer Infiltrationsanästhesie eingesetzt werden. Die Berechnung der empfohlenen Maximaldosen auf Basis des Körpergewichts ist erforderlich, um eine Überdosierung von Lokalanästhetika zu vermeiden. Die Allgemeinanästhesie gilt bei der Dermatochirurgie als sicher und hat eine geringe Nebenwirkungsrate. Allerdings ist bei Kindern im ersten Lebensjahr aufgrund potentieller langfristiger neurologischer Nebenwirkungen Vorsicht angebracht. NSAR und Opioide spielen bei der Analgesie von Kindern eine bedeutende Rolle. SCHLUSSFOLGERUNGEN Dieser Artikel gibt eine Übersicht über die derzeit verfügbaren Daten zu Analgesie, Anästhesie und Komplikationen, die im Rahmen der pädiatrischen Dermatochirurgie auftreten können. Diese Daten können dabei helfen, die Sicherheit und Qualität der Versorgung zu optimieren und die Beratung der Eltern zu verbessern.

Abstract
BACKGROUND AND OBJECTIVES Articaine is more and more used in third molar surgery under local anesthesia (LA). The objectives of this analysis were to characterize the pharmacokinetics of articaine for this type of surgery and to simulate dosing regimens. METHODS Non-linear mixed-effects modeling conducted in Monolix 4.4.0 was used to describe articaine plasma concentration-time data from 20 patients. Monte Carlo simulations were then performed to evaluate the probability of cardiotoxic target attainment (PCTA) of various dosage regimens. RESULTS Articaine concentration data were best described by a linear one-compartment model, with an additional depot compartment for submucosal route with a zero-order transfer to central compartment. Age and gender were found to influence duration transfer (Tk0) and elimination rate constant (Ke), respectively. Simulated maximum recommended dose regimen (7mg/kg) had a PCTA of 0%. Simulated higher doses of 10mg/kg and 15mg/kg had a PCTA of 0% and about 1-4%, respectively. CONCLUSIONS The model adequately described the articaine pharmacokinetics. This is the first PK model qualified for articaine administered by submucosal route. The simulations suggest that maximum recommended dose regimen is safe concerning the cardiotoxicity in healthy patients.

Abstract
BACKGROUND Children undergoing dermatosurgical procedures require, unlike adults, particular attention; the administration of various analgesics, anesthetics or sedatives requires a thorough knowledge of drug pharmacokinetics and pharmacodynamics. Furthermore, there are concerns that drugs used for sedation/general anesthesia may result in anesthetic/analgesic complications in children undergoing surgery, with a risk of impaired mental development. OBJECTIVES Based on our clinical experience and a literature review, we illustrate the most commonly used analgesic, anesthetic and sedative drugs in pediatric dermatosurgery, and identify risk factors and complications following dermatosurgical procedures. RESULTS Topical anesthetics can be used in children for superficial dermatologic procedures or prior to infiltration anesthesia. Maximum recommended doses based on body weight should be calculated in order to avoid overdosage of local anesthetics. General anesthesia in dermatosurgery is considered safe and has a low rate of side effects. However, caution is advised in children under the age of one due to potential long-term neurological side-effects. NSAIDs and opioids play a significant role in analgesia for children. CONCLUSIONS This article reviews currently available data on analgesia, anesthesia and complications that may arise in pediatric dermatosurgery. These data may be useful in optimizing the safety and quality of care and in improving parent counseling.

Abstract
Background There are no studies regarding 4% articaine infiltration injection into the retro-molar area for an impacted lower third molar (LITM) surgery. This study aimed to evaluate the efficacy of infiltration using 1.7 ml (single cartridge: SC) of 4% articaine versus 3.4 ml (double cartridges: DC) of 4% articaine with 1:100,000 epinephrine in LITM surgery. Method This study involved 30 healthy patients with symmetrical LITM. The patients were assigned to receive either a DC or SC of 4% articaine with 1:100,000 epinephrine as a local anesthetic for each operation. Onset, duration, profoundness, need for additional anesthetic administration, total volume of anesthetic used, vitality of the tooth, and pain score during operation were recorded. Results The DC of 4 % articaine had a significantly higher success rate (83.3%) than did the SC (53.3%; P < 0.05). The duration of soft tissue anesthesia was longer in the DC group. The intra-operative pain was higher in the SC group with a significant (P < 0.05) requirement for a supplementary local anesthetic. Conclusion We concluded that using DC for the infiltration injection had a higher success rate, longer duration of anesthesia, less intra-operative pain, and a lower amount of additional anesthesia than SC in the surgical removal of LITM. We recommend that a DC of 4% articaine and a 1:100,000 epinephrine infiltration in the retro-molar region can be an alternative anesthetic for LITM surgery.

Abstract
OBJECTIVES Articaine, a popular and rapidly acting local anesthetic in dentistry, has been also found to be beneficial in ambulatory spinal anesthesia. Analgesia in the intraoperative and immediate postoperative period may be further improved by adding fentanyl to the local anesthetic solution for spinal anesthesia. The aim was to evaluate dose-dependency of analgesia and side effects associated with intrathecal fentanyl additive to articaine for spinal anesthesia in knee arthroscopy patients. METHODS In this randomized, observer- and patient-blinded study, 90 adult patients scheduled for elective ambulatory knee arthroscopy under spinal anesthesia were randomized into three groups: plain articaine 60 mg with saline (group AF0), articaine 60 mg with fentanyl 10 µg (group AF10) or 20 µg (group AF20) in a total volume of 1.9 ml. The blinded observer tested the sensory and the motor block, and performed telephone interviews on the first and seventh postoperative days. RESULTS The median (IQR) duration of sensory block at the dermatomal level of T10 was significantly longer in groups AF10, 69 min (56) and AF20, 69 min (45) than in group AF0, 41 min (35) (p = 0.013). Motor block duration was similar in all groups (median 120 min). Group AF20 patients experienced pruritus significantly more often than patients in the other groups (p = 0.039). No acute or late anesthetic side effects occurred, and satisfaction with the anesthetic technique was the same in all groups (97% satisfied). CONCLUSIONS Fentanyl 10 or 20 µg as additive to articaine for spinal anesthesia prolonged the duration of sensory block significantly and similarly. Fentanyl 20 µg was more often associated with pruritus than fentanyl 10 µg.

Prilocaine spinal anesthesia for ambulatory surgery: A review of the available studies. Anaesth Crit Care Pain Med 2016; 35:417-421.

Abstract
Transient neurologic symptoms (TNS) led to the abandonment of intrathecal lidocaine. We reviewed the published literature for information about the duration of action and side effects of intrathecal prilocaine, which has been recently reintroduced in Europe. Medline and EMBASE databases were searched for the time period from 1966 to 2015. Fourteen prospective and one retrospective study were retrieved. The duration of the surgical block can be adjusted using doses between 40 and 80mg. Hyperbaric prilocaine in doses as low as 10mg can be used for perianal procedures. Four cases of TNS in 486 patients were reported in prospective studies, and none in 5000 cases in a retrospective data set. Spinal prilocaine appears to be safe and reliable for day case anesthesia. However, as chloroprocaine has a shorter duration and a lower risk of TNS and urinary retention, the indications for prilocaine remain to be defined.
