Abstract
Background This study aimed to compare the success rate of inferior alveolar nerve (IAN) anesthesia in the mandibular first molars with symptomatic irreversible pulpitis using two anesthetic solutions of prilocaine and mepivacaine. Materials and Methods The current randomized controlled clinical trial was conducted on 100 patients in two groups (n = 50). Standard injection of IAN block (IANB) was performed using two cartridges of 3% mepivacaine plain in the first group and using two cartridges of 3% prilocaine with 0.03 IU felypressin in the second group. Fifteen minutes after injection, the patients were asked about lip anesthesia. In case of a positive answer, the tooth was isolated with a rubber dam. Success was defined as no or mild pain on the basis of the visual analog scale recording upon access cavity preparation, entry into the pulp chamber, and initial instrumentation. Data were analyzed with SPSS 17 using the Chi-square test, and P < 0.05 was set as statistically significant. Results The patients' pain severities during the three stages were significantly different (P = 0.001, 0.0001, and 0.001, respectively). The success rate of IANB during access cavity preparation was 88% with prilocaine and 68% with mepivacaine. This rate during entry into the pulp chamber was 78% and 24%, respectively, which was 3.25 times higher with prilocaine than mepivacaine. The success rates during instrumentation were 32% and 10%, respectively, which was 3.2 times higher with prilocaine than mepivacaine. Conclusion The success rate of IANB in the teeth with symptomatic irreversible pulpitis was higher using 3% prilocaine with felypressin than using 3% mepivacaine.

Abstract
We aimed to develop and validate a new graph embedding algorithm for embedding drug-disease-target networks to generate novel drug repurposing hypotheses. Our model denotes drugs, diseases and targets as subjects, predicates and objects, respectively. Each entity is represented by a multidimensional vector and the predicate is regarded as a translation vector from a subject to an object vectors. These vectors are optimized so that when a subject-predicate-object triple represents a known drug-disease-target relationship, the summed vector between the subject and the predicate is to be close to that of the object; otherwise, the summed vector is distant from the object. The DTINet dataset was utilized to test this algorithm and discover unknown links between drugs and diseases. In cross-validation experiments, this new algorithm outperformed the original DTINet model. The MRR (Mean Reciprocal Rank) values of our models were around 0.80 while those of the original model were about 0.70. In addition, we have identified and verified several pairs of new therapeutic relations as well as adverse effect relations that were not recorded in the original DTINet dataset. This approach showed excellent performance, and the predicted drug-disease and drug-side-effect relationships were found to be consistent with literature reports. This novel method can be used to analyze diverse types of emerging biomedical and healthcare-related knowledge graphs (KG).

Abstract
Objective: To investigate the effect of maxillary single and multiple rooted teeth on the success rate of buccal infiltration anesthesia. Subjects and Methods: This clinical study was performed by dividing the participants into three groups. Group one included 30 patients with upper anterior teeth, group two 23 patients with upper premolars teeth and group three 39 patients with upper molars for extraction. Onset time of anesthtic action was evaluted by using electronic pulp tester. Pulp testing assessments were carried out immediately before the injection and at the intervals of 2 mins following the injection until the anesthetic success obtains. Results: Seventy-nine patients in this study secured anesthetic success within study duration time (10 min). However, there were 13 patients with dental anesthesia failures (3 patients with single rooted teeth and 10 patients with multiple rooted teeth). There were no significant differences in the mean onset time of pulpal anesthesia between the anterior, middle and posterior teeth (P value = 0.449). Clinically, patients with single rooted teeth reported faster dental anesthesia and earlier teeth extraction than patients with multiple rooted teeth. Conclusion: This study showed that the single rooted teeth have faster pulpal anesthesia and early extraction than teeth with multiple roots but not statistically significant. Administration of extra local anesthetic cartridge or using intraseptal injection technique can be a solution to overcome the failure of anesthesia in the maxillary posterior teeth.

Abstract
Objective To investigate the speed of action and injection discomfort of 2% lidocaine and 3% prilocaine for upper teeth extractions. Materials and Methods Forty-six patients were included in the prilocaine 3% group, and 46 in the lidocaine 2% control group. After all injections, soft and hard tissue numbness was objectively gauged by dental probe at intervals of 15 s. Moreover, the pain of the injections was recorded by the patients after each treatment on standard 100 mm visual analog scales, tagged at the endpoints with "no pain" (0 mm) and "unbearable pain" (100 mm). Results There were no significant differences in the meantime of first numbness to associated buccal, palatal mucosa, and tooth of patients in the lidocaine and prilocaine buccal infiltration groups (P = 0.56, 0.37, and 0.33). However, clinically, the patients in prilocaine group recorded earlier buccal, palatal mucosa, and teeth numbness than those in lidocaine group. With regards to the discomfort of the needle injections, there was a significant difference for lidocaine and prilocaine groups when comparing the post buccal scores with the post palatal injection scores (t-test: P < 0.001). Lidocaine and prilocaine buccal injections were significantly more comfortable than palatal injections. Conclusions Using 2% lidocaine and 3% prilocaine for extractions of upper maxillary teeth produces similarly successful anesthesia. Clinically, prilocaine has slightly rapid onset of action, earlier buccal mucosa, hard palate, and teeth numbness. Prilocaine and lidocaine buccal injection was significantly more comfortable than palatal injection.

Abstract
Anesthesia followed by placement in the prone position takes time and may result in complications. This study aimed to evaluate the feasibility of awake nasotracheal fiberoptic intubation and self-positioning followed by anesthesia induction in prone-positioned patients under general anesthesia.Sixty-two patients (ASA physical status I-II) scheduled for awake nasotracheal fiberoptic intubation and prone self-positioning before surgery under general anesthesia were selected. Patient preparation began with detailed preoperative counseling regarding the procedure. Premedication with sedative and antisialagogue was followed by airway anesthesia with topical lidocaine; then, awake nasotracheal fiberoptic intubation was carried out. The patients then positioned themselves comfortably before induction of general anesthesia. The changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), incidence of coughing or gagging, and rate pressure product (RPP) were assessed. Statistical analysis was performed with repeated-measures one-way analysis of variance.Fifty-eight of the 62 patients completed prone self-positioning smoothly. Compared with values before intubation, SBP, DBP, HR, and RPP were slightly increased after intubation, although the difference was not statistically significant (P > 0.05). One patient had moderate coughing and 1 patient had gagging during prone self-positioning, which were tolerable.These findings indicated that awake nasotracheal fiberoptic intubation and self-positioning followed by induction of anesthesia is safe and feasible alternative to routine prone positioning after induction of general anesthesia.

Abstract
BACKGROUND The authors studied the hemodynamic effect influent by using the novel high concentration of lidocaine HCl for surgical removal impacted lower third molar. The objective of this study was to evaluate the hemodynamic change when using different concentrations of lidocaine in impacted lower third molar surgery. METHODS Split mouth single blind study comprising 31 healthy patients with a mean age of 23 years (range 19-33 years). Subjects had symmetrically impacted lower third molars as observed on panoramic radiograph. Each participant required 2 surgical interventions by the same surgeon with a 3-week washout period washout period. The participants were alternately assigned one of two types of local anesthetic (left or right) for the first surgery, then the other type of anesthetic for the second surgery. One solution was 4% lidocaine with 1:100,000 epinephrine and the other was 2% lidocaine with 1:100,000 epinephrine. A standard IANB with 1.8 ml volume was used. Any requirement for additional anesthetic and patient pain intra-operation was recorded. Post-operatively, patient was instructed to fill in the patient report form for any adverse effect and local anesthetic preference in terms of intra-operative pain. This form was collected at the seven day follow up appointment. RESULTS In the 4% lidocaine group, the heart rate increased during the first minute post-injection (P < 0.05). However, there was no significant change in arterial blood pressure during the operation. In the 2% lidocaine group, there was a significant increase in arterial blood pressure and heart rate in the first minute following injection for every procedure. When the hemodynamic changes in each group were compared, the 4% lidocaine group had significantly lower arterial blood pressure compared to the 2% lidocaine group following injection. Post-operatively, no adverse effects were observed by the operator and patient in either local anesthetic group. Patients reported less pain intra-operation in the 4% lidocaine group compared with the 2% lidocaine group (P < .05). CONCLUSIONS Our results suggest that a 4% concentration of lidocaine HCl with 1:100,000 epinephrine has better clinical efficacy than 2% lidocaine HCl with 1:100,000 epinephrine when used for surgical extraction of lower third molars. Neither drug had any clinical adverse effects.

Abstract
Objective: To analyze the side effects and complications following intraosseous anesthesia (IA), comparing them with those of the conventional oral anesthesia techniques.
Material and method: A simple-blind, prospective clinical study was carried out. Each patient underwent two anesthetic techniques: conventional (local infiltration and locoregional anesthetic block) and intraosseous, for respective dental operations. In order to allow comparison of IA versus conventional anesthesia, the two operations were similar and affected the same two teeth in opposite quadrants. Heart rate was recorded in all cases before injection of the anesthetic solution and again 30 seconds after injection. The complications observed after anesthetic administration were recorded.
Results: A total of 200 oral anesthetic procedures were carried out in 100 patients. Both IA and conventional anesthesia resulted in a significant increase in heart rate, though the increase was greater with the latter technique. Incidents were infrequent with either anesthetic technique, with no significant differences between them. Regarding the complications, there were significant differences in pain at the injection site, with more intense pain in the case of IA (x2=3.532, p=0.030, Φ2=0.02), while the limitation of oral aperture was more pronounced with conventional anesthesia (x2=5.128, p<0.05, Φ2=0.014). Post-anesthetic biting showed no significant differences (x2=4.082, p=0.121, Φ2=0.009).
Conclusions: Both anesthetic techniques significantly increased heart rate, and IA caused comparatively more pain at the injection site, while limited oral aperture was more frequent with conventional anesthesia. Post-anesthetic biting showed no significant differences between the two techniques.

Review of the literature published in the last decade. J Clin Exp Dent 2012; 4:e107-11. [PMID: 24558534 PMCID: PMC3908793 DOI: 10.4317/jced.50590] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2011] [Accepted: 01/05/2012] [Indexed: 11/22/2022] Open
Abstract
Objective: The use of local anesthetics associated to vasoconstrictor agents in dentistry is thoroughly justified and is widely extended, but we cannot ignore the fact that anesthetic infiltration poses risk of complications throughout the dental treatment period. The objective of the present review is to document the reported effects the use of the local anesthetics most widely employed in dentistry, with or without association to vasoconstrictor agents may have in patients with any sort of cardiopathy.
Study Design: We have searched for randomized clinical trials on the assessment of the cardiovascular effects of local anesthetics used in dentistry, without limits as regards age or sex, conducted in patients with any type of cardiopathy which were published during the last decade and were index-linked in Cochrane, Embase and Medline.
Results: We have found six randomized clinical trials index-linked in Medline and Cochrane in the past ten years. These trials compare different types of anesthetics: lidocaine 2%, mepivacaine 2%, prilocaine 2% , associated or not to different vasoconstrictor concentrations such as adrenaline or felypressin. The cardiopathies affecting the patients included in the different trials range from hypertension, ischemic heart disease, arrythmias, chronic coronary disease to heart transplantation.
Conclusions: The use of anesthetics associated to vasoconstrictor agents is justified in the case of patients with cardiopathies (once we get over the period in which any type of dental manipulation is contraindicated) and in controlled hypertensive patients. In any case, we must be very careful with the choice and execution of the anesthetic technique, being it possible to use a dose between 1.8 and 3.6 ml, on a general basis. Further studies are necessary to establish the effects of these drugs on severe hypertensive patients or in patients with other more advanced cardiopathies.
