Introduction. The anterior and middle superior alveolar (AMSA) nerve block is an alternative technique of local anesthesia in the maxilla, unpredictably efficient for pulpal anesthesia. The aim of this study was to determine the anesthetic efficacy of the AMSA injection for pulpal anesthesia, using computer-controlled injection system or conventional syringe, and two local anesthetic solutions with or without adrenaline. Methods. The authors administered two AMSA injections during two separate appointments, utilizing the computer-controlled system and conventional syringe to 40 subjects, divided into two groups of 20 subjects each depending on the local anesthetic used. A pulp tester was used to test the achieved anesthesia of the central and lateral incisors, canine, first and second premolars, and the first molar in 10-minute cycles over a period of 60 minutes. Duration of anesthesia for all the mentioned teeth was also determined for both the anesthetic solutions and ways of application. Results. The AMSA injection with both types of equipment was successful, showing slow onset, satisfying intensity, and declining duration of pulpal anesthesia at the last two measurements. Local anesthetic with vasoconstrictor exhibited a significantly longer pulpal anesthesia. Conclusion. The AMSA nerve block could be recommended for achieving pulpal anesthesia of maxillary teeth from the region of the first incisor to the second premolar.

Introduction. The anterior and middle superior alveolar nerve block was claimed to be unpredictably efficient for clinical application. Objective. The aim of this report was to establish the efficacy of the anterior and middle superior alveolar nerve block, applied with a computer-controlled injection system or a conventional syringe, for upper premolars extraction. Methods. Sixty healthy adults were divided into two groups regarding the device used as follows: the first group was injected by a computer-controlled injection system, and the second group by a conventional syringe. Pain ratings were obtained via a visual analog scale (VAS) and a verbal rating scale (VRS). Results. Anterior and middle superior alveolar injection enabled a painless extraction in all patients, regardless of the local anesthetic or injection system used. It was slightly less painful when administered by a computer-controlled injection system, but insignificantly when evaluated by VRS. Conclusion. The anterior and middle superior alveolar nerve block may be recommended if maxillary permanent premolars have to be extracted.

A computer-controlled injection-correction system has been developed to continuously and completely mitigate the adverse effects of membrane compliance for undrained testing of granular soils. The system was developed with the explicit idea that it could be quickly and easily adapted to most any up to date triaxial testing apparatus. A relationship between effective confining stress and volumetric compliance can be predetermined, as volumetric-compliance errors have been shown to be a direct and repeatable function of effective confining stresses for a given material. The predetermination of volumetric-compliance errors represents a suitable basis for control of injection–removal compensation for membrane compliance during undrained testing. A closed-loop computer-controlled system continuously monitors changes in sample effective confining stresses such that precalculated volumetric-compliance errors can be continuously offset by injecting or removing volumes of water equal to those errors throughout the duration of each test. The validity of the injection system was verified by comparison of the compensated tests to results of large-scale (300 mm diameter) tests of the same materials, as compliance effects for large-scale tests of this material were negligible.

ABSTRACT Introduction Anterior middle superior alveolar (AMSA) block is a nerve block technique in conjunction with computer-controlled local anesthetic delivery (CCLAD) system. Anterior middle superior alveolar produces local anesthesia (LA) to the maxillary teeth from second premolar to the central incisor including the hard palate and corresponding soft-tissue of both buccal and palatal side, with single palatal injection. Aim To evaluate efficacy of AMSA block for extraction of maxillary first premolar. Study design In randomized single blind, split mouth clinical trial, the 14 patients received the conventional buccal-palatal (B-P) anesthesia on one side and CCLAD anesthesia AMSA for other side. The treatment consisted of bilateral extraction of maxillary first premolars for orthodontics. Pain perception ratings were obtained by using 10 point visual analog scale (VAS). Results A total of 100% cases had painless injection with CCLAD, whereas 28.57% patients had painless injection experience with conventional LA. In all cases, there was no pain during extraction on both sides. With CCLAD, buccal retraction was painful in four cases whereas palatal retraction was painful in one case. Conclusion Anterior middle superior alveolar block injected with CCLAD is better as LA technique for extraction of maxillary first premolar as compared to B-P approach.

Bacground/Aim. The efficient dental anesthesia, which is related to the clinically adequate depth, duration and the width of anesthetic field, is an important prerequisite for successful dental treatment. The aim of this study was to investigate and compare the pulpal anesthesia and cardiovascular parameters after the anterior middle superior alveolar (AMSA) nerve block with 4% articaine with epinephrine administered by conventional cartridge-syringe and computer- controlled local anesthetic delivery system (CCLADS). Methods. This controlled double-blind cross-over randomized clinical study included 38 healthy volunteers. Efficacy of pulpal anesthesia after the AMSA nerve block was evaluated by measuring a success rate, onset and duration of pulpal anesthesia, using an electrical pulp tester. The parameters of cardiovascular function (systolic and diastolic blood pressure, heart rate) were monitored noninvasively. Results. Successful pulpal anesthesia of all tested teeth was obtained in 57.9% participants with CCLADS and in 44.7% participants with conventional syringe. The onset time was not significantly different between two investigated groups. The pulpal anesthesia duration was not significantly different neither within nor between investigated groups. The systolic and diastolic blood pressures were significantly decreased in both investigated groups, in comparison with the baseline values. Heart rate significantly decreased within CCLADS from 10th to 30th minute when compared to baseline. Conclusion. The efficacy of pulpal anesthesia and safety of cardiovascular profile of 0.6 mL of articaine with epinephrine (1:100.000) delivered with CCLADS were improved in comparison to the conventional syringe delivery. Significant changes of cardiovascular function were not observed.

Background. Local anesthesia is given to decrease pain perception during dental treatments, but it may itself be a reason for pain and aggravate the dental fear. Computer-controlled local anesthetic delivery system (CCLADS) is one of the alternatives for decreasing the patients’ pain during local anesthesia. This study compared the time required for the recovery from anesthesia, pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia with CCLADS, a standard self-aspirating syringe and a conventional disposable 2-mL syringe. Methods. The study was conducted on 90 subjects (an age group of 20-40 years), who suffered from sensitivity during cavity preparation. They were randomly divided into three groups of 30 individuals each to receive intraligamentary anesthesia (2% lignocaine with 1:80,000 adrenaline) using either of the three techniques: CCLADS, a standard self-aspirating syringe, or a conventional disposable 2-mL syringe. The onset of anesthesia, time required for recovery from anesthesia (in minutes), pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia were recorded. Results. The time required for the onset of anesthesia and recovery from anesthesia was shorter with CCLADS (4.83±2.31 and 34.2±1.895, respectively) as compared to the standard self-aspirating group (10.83±1.90 and 43.5±7.581, respectively) and the conventional group (11.00±2.03 and 43.5±6.453, respectively) (P<0.001). The patients in the CCLADS group experienced no pain during local anesthesia administration as compared to the patients in the self-aspirating and conventional groups. The CCLADS and self-aspirating groups showed lower pain response as compared to the conventional group for pain after 24 hours. Conclusion. CCLADS can be an effective and pain-free alternative to conventional local anesthetic procedures.

The article is based on the analysis of the literature and the latest international guidelines of dental associations in order to systematize the knowledge of doctors. The paper discusses local anesthetic agents such as lignocaine, benzocaine, articaine or mepivacaine, many times used in daily practice by dentists. Various anesthetic techniques, including computer-controlled systems for administering anesthesia, are described in the publication. The topic of teething preparations containing anesthetics and the risks associated with their use were also discussed, so that dentists could warn against their use of carers and parents of children and thus reduce the number of complications after their use. Contraindications to the use of analgesia have been presented and the complications that may occur after their administration have been characterized, thanks to which the right choice of the appropriate agent for analgesia will reduce the risk of possible complications after local anesthesia. The authors hope that after reading the article, doctors will be confident in using the benefits of local anesthetics.

The purpose of this prospective, randomized, double blind study was to compare the onset and duration periods of pulpal anesthesia using 2% lidocaine with 1:100,000 epinephrine, 4% articaine with 1:100,000 epinephrine and 4% articaine with 1:200,000 epinephrine in inferior alveolar nerve block (IANB). Thirty subjects received 1.8 mL of each of the three local anesthetic solutions in IANB. Onset and duration periods of pulpal anesthesia were determined using electric pulp stimulation. The mean time of onset of pulpal anesthesia was 8.7, 7.4 and 7.7 min and the mean duration of pulpal anesthesia was 61.8, 106.6 and 88.0 min for 2% lidocaine with 1:100,000 epinephrine, 4% articaine with 1:100,000 epinephrine and 4% articaine with 1:200,000 epinephrine, respectively. For onset, there was only a significant difference between 2% lidocaine with 1:100,000 epinephrine and 4% articaine with 1:100,000 epinephrine (p=0.037). For duration, there was significant difference for all the local anesthetic solutions (p≤0.05). In conclusion, 4% articaine with 1:100,000 epinephrine exhibited faster onset and also had longest duration of pulpal anesthesia in IANB.

ABSTRACT The local anesthetic drugs presently available and used in dentistry represent the safest and most effective drugs in all of medicine for the prevention and management of pain. One drawback associated with intraoral local anesthesia is patients’ fear of injections .and the perception that these are painful. Recent advances have resulted in the use of computer-controlled local anesthetic delivery vehicles to regulate the delivery and rate of flow of local anesthetics at the injection site, lessening potential discomfort associated with injections. New injection techniques that provide reliable anesthesia, depending on the technique and area of anesthesia necessary have been discussed.

There is evidence that the Computer-Controlled Local Anesthetic Device (CCLAD) decreases the pain of oral injections. The purpose of this study was to evaluate injection pain of the inferior alveolar nerve block (IANB) using the CCLAD in an upright position versus a supine position. Additionally, we evaluated solution deposition pain with the CCLAD when compared to previous studies using a traditional syringe. One hundred ten asymptomatic subjects were randomly given IANBs using 2% lidocaine with 1:100,000 epinephrine while in an upright sitting position and supine position, at 2 different appointments, spaced at least 2 weeks apart. Each subject rated the pain for needle insertion, needle placement, and solution deposition on a Heft-Parker visual analogue scale. Pain ratings were compared between the upright and supine positions using a repeated-measures analysis of variance with post hoc testing using the Tukey-Kramer procedure. Moderate to severe pain was reported by 10% to 13% of the patients for needle insertion, 74% to 75% for full needle placement, and 8% to 10% for solution deposition. There was no significant difference between groups for phases of the injection. When comparing the injection phases within the groups, the needle placement phase of the injection was statistically more painful than both the needle insertion phase and solution deposition phase (p = .0001). Using the CCLAD, IANB injection pain of the supine and upright positions was not statistically different. Needle placement was the most painful phase of the injection. Solution deposition pain was less with the CCLAD when compared to other studies of the IANB using a traditional syringe.
