Rabinowitz Y, Williams S, Triana RR, Khan MTF, Hooker KJ, Dubey A, Tewari A, Holmes E, Phero JA. Assessing the Efficacy of Buffered Versus Nonbuffered Lidocaine in Dental Extractions: A Double-Blinded Randomized Controlled Trial. J Oral Maxillofac Surg 2024; 82:684-691. [PMID: 38554734 DOI: 10.1016/j.joms.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Revised: 02/19/2024] [Accepted: 03/06/2024] [Indexed: 04/02/2024]
Abstract
BACKGROUND Injections using buffered lidocaine may decrease discomfort, have a quicker onset, and be a more efficacious local anesthetic. Previous studies have been inconclusive in the oral context. PURPOSE To address if bicarbonate buffered 2% lidocaine can decrease pain from the use of local anesthesia, has a quicker onset time, and is more efficacious. STUDY DESIGN The design was a single-center double-blinded randomized control trial, set in an outpatient oral and maxillofacial clinic housed in the University of Cincinnati Medical Center. Inclusion criteria for the study were patients requiring a single tooth extraction due either to caries or periodontal disease. PREDICTOR VARIABLE The predictor variable was the local anesthetic used either nonbuffered 2% lidocaine with 1:100,000 epinephrine (control) or bicarbonate buffered 2% lidocaine with 1:100,000 epinephrine (study) was randomly assigned. MAIN OUTCOME VARIABLES Primary outcome variables were injection pain score, and postoperative pain, time to anesthetic onset, and the number of rounds of injections required to achieve adequate anesthesia. COVARIATES The covariates were jaw involved, age, sex, and race, American Society of Anesthesiologists score, body mass index, current tobacco use, history of psychiatric illness, chronic pain, and preoperative pain score. ANALYSES Test statistics were calculated using Wilcoxon rank-sum test, Kruskal-Wallis test, Spearman rank correlation test, χ2 test for bivariate analyses, and Fisher's exact test. P values ≤ .05 were considered statistically significant. RESULTS The final sample was 114 subjects. The mean age of the sample was 42.97 years, standard deviation ±13.43 years. The sample was 39.47% male. The racial demographics were Caucasian (62.28%) and African American (33.33%). Buffered lidocaine did not have a statistically significant relationship with any of the outcomes. The jaw involved had a statistically significant association to the injection pain score (P value = .006), and the number of rounds of anesthetic required (P value = .047). Age showed a statistically significant association to injection pain score (P value = .032), and the number of rounds of anesthetic required (P value = .027). Finally, preoperative pain had a statistically significant relationship with injection pain score (P value = < .001). CONCLUSION AND RELEVANCE In this study, bicarbonate buffered lidocaine did not exhibit any discernible advantages over nonbuffered lidocaine for any study outcomes.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic immune-mediated inflammatory skin disease characterized by abscesses and inflammatory nodules, and occasionally tunnels and scars, in the axillae, groin, and inframammary areas. OBJECTIVE HS can be challenging to diagnose because it mimics localized soft-tissue infection. The process of differentiating HS from soft-tissue infection is discussed. Patients with HS frequently visit emergency departments (EDs) for acute management of pain and drainage from HS lesions. This review updates emergency and urgent care physicians on how to educate and initiate treatment for patients with HS, and to coordinate care with dermatologists and other physicians early in their disease course. DISCUSSION Recent updates on the epidemiology, diagnosis, and management of HS are reviewed. CONCLUSIONS Practice variations between how care for HS is provided in the ED setting and what HS treatment guidelines recommend are identified.

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
Introduction: This study aims to compare the efficacy of a combination of an inferior alveolar nerve block (IANB) plus buccal infiltration using 4% articaine versus 2% lignocaine in achieving anesthesia of lower first molar teeth with irreversible pulpitis. Materials and Methods: Seventy adult patients were selected. A random sequence list was employed to administer IANB plus buccal infiltration. After the onset of lip numbness, cold test and electric pulp testing were performed. Five patients, four missed blocks and one no bleeding, were excluded. Heft Parker Visual Analog Scale scores during pulp extirpation were recorded. The data of sixty-five patients were statistically analyzed using Chi-square and Mann–Whitney U-test. Results: The success rate after lip-numbness for articaine is 91.42% and for lignocaine is 94.28%. The difference is statistically, not significant (P = 0.6425). During access, the success rate for lignocaine is 96.87%, whereas 96.96% for articaine. This difference is also not significant (P = 0.982366). Conclusion: IANB plus buccal infiltration using articaine or lignocaine is equally effective in anesthetizing mandibular first molar with irreversible pulpitis.

Abstract
Research is the search for new, generalisable knowledge (Truth in the Universe) to improve our collective ability to correctly diagnose and treat human suffering. In the formal sense, medical research implies both creating new knowledge, and also disseminating that new knowledge as well as putting it into practice. This is the first paper in this Research Primer. It briefly covers why each emergency physician should know and care about research. The paper reminds us that it does not take a physician to do research, but that it is the practicing physician who best knows what new knowledge is needed at the bedside. It introduces the scope of the other papers included in this special issue. The paper reviews the definitions of research and the scope of research practice in emergency medicine; overviews the hows and whys of research, as well as discusses the research question, study justification, literature search and touching on research design.

Abstract
INTRODUCTION Incision and drainage of symptomatic emergency patients with facial swelling is painful even after local anesthetics are administered. The purpose of this prospective, randomized, double-blind study was to compare the pain of infiltration and the pain of an incision and drainage procedure of a buffered versus a nonbuffered 4% lidocaine formulation in symptomatic emergency patients presenting with a diagnosis of pulpal necrosis, associated periapical area, and an acute clinical swelling. METHODS Eighty-eight emergency patients were randomly divided into 2 groups to receive 2 intraoral infiltration injections (mesial and distal to the swelling) of either 4% lidocaine with 1:100,000 epinephrine buffered with 0.18 mL 8.4% sodium bicarbonate using the Onpharma (Los Gatos, CA) buffering system or 4% lidocaine with 1:100,000 epinephrine. Subjects rated the pain of needle insertion, needle placement, and solution deposition for each injection using a 170-mm visual analog scale. An incision and drainage procedure was performed, and subjects rated the pain of incision, drainage, and dissection on a 170-mm visual analog scale. RESULTS No significant differences between the buffered and nonbuffered 4% lidocaine formulations were found for needle insertion, placement, and solution deposition of the infiltration injections or for the treatment phases of incision, drainage, and dissection. CONCLUSIONS Buffering a 4% lidocaine formulation did not significantly decrease the pain of infiltrations or significantly decrease the pain of the incision and drainage procedure when compared with a nonbuffered 4% lidocaine formulation in symptomatic patients with a diagnosis of pulpal necrosis and associated acute swelling.

Abstract
INTRODUCTION Articaine is superior to lidocaine when used as a primary buccal infiltration of the mandibular first molar. Buffered local anesthetics have been purported to improve anesthetic success. Buffering a 4% articaine formulation may increase the success of a mandibular first molar buccal infiltration. The purpose of this study was to compare the degree of pulpal anesthesia obtained with a buffered 4% articaine with 1:100,000 epinephrine formulation versus a nonbuffered 4% articaine with 1:100,000 epinephrine formulation as a primary buccal infiltration of the mandibular first molar. METHODS Eighty adults randomly received mandibular buccal infiltrations using 4% articaine with 100,000 epinephrine buffered with 8.4% sodium bicarbonate (18 mEq) and 4% articaine with 1:100,000 epinephrine in a double-blind manner at 2 separate appointments. An electric pulp tester was used to test the first molar for pulpal anesthesia every 30 seconds for the first 5 minutes and every minute for the remaining 55 minutes. Successful pulpal anesthesia was defined as 2 consecutive 80/80 readings with the electric pulp tester. Pain ratings for each injection were recorded as well as the onset time of pulpal anesthesia. RESULTS Anesthetic success rates for buffered articaine and nonbuffered articaine were 71% and 65%, respectively. There was no significant difference between the formulations (P = .3018). No significant differences were found between the 2 formulations for pain of injection or onset of anesthesia. CONCLUSIONS Buffered articaine did not provide any advantage over nonbuffered articaine for anesthetic success, anesthesia onset, or pain of injection for a primary buccal infiltration of the mandibular first molar.

Abstract
INTRODUCTION The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of buffered with nonbuffered 2% lidocaine with 1:80,000 epinephrine solution for inferior alveolar nerve (IAN) block in patients with mandibular posterior teeth experiencing symptomatic irreversible pulpitis. METHODS Eighty adult patients diagnosed with symptomatic irreversible pulpitis of a mandibular posterior tooth were selected. The patients received 2 cartridges of either 2% lidocaine with 1:80,000 epinephrine buffered with 0.18 mL 8.4% sodium bicarbonate or 2% lidocaine with 1:80,000 epinephrine with 0.18 mL sterile distilled water using conventional IAN block injections. Endodontic access preparation was initiated 15 minutes after injection. Lip numbness was required for all the patients. Success was determined as no or mild pain on the basis of Heft-Parker visual analog scale recordings upon access cavity preparation or initial instrumentation. Data were analyzed by the t, Mann-Whitney, and chi-square tests. RESULTS The success rates were 62.5% and 47.5% for buffered and nonbuffered groups, respectively, with no significant differences between the two groups (P = .381). CONCLUSIONS Buffering the 2% lidocaine with 1:80,000 epinephrine with 8.4% sodium bicarbonate did not improve the success of the IAN block in mandibular molars in patients with symptomatic irreversible pulpitis.
