Pain control by means of local anesthesia is an intrinsic part of clinical practice in dentistry. Several studies evaluated intraligamental anesthesia using a computer-controlled anesthetic device in children. There is a need to provide a clinical guide for the use of computerized intraligamental anesthesia in children. Intraligamental anesthesia using a computer-controlled anesthetic device was found to cause significantly lower pain perception scores and lower pain-related behavior than traditional techniques. This device proven to be effective in restorative and pulp treatment in children; however, its effectiveness in primary teeth extraction is controversial. It is important to withdraw recommendations necessity of future studies concerning the side effects of computerized intraligamental anesthesia in children. The present study aims to review different clinical aspects of computerized intraligamental anesthesia in children along with the side-effects, type of local anesthesia and postoperative pain of this technique. This study provides dentists with a clinical guide for the use of computerized intraligamental anesthesia.

Background: Fear of local anesthesia (LA) is a significant impediment to dental care as many patients delay or avoid treatment to avert pain. Computer-controlled local anesthetic delivery system (CCLAD), with constant and controlled rate of flow, present a painless alternative. The present study aimed to compare anxiety and pain perceived with conventional and computerized systems, for different stages of anesthesia delivery when administering various nerve blocks. Methods: One hundred patients requiring bilateral LA participated in the study. One side was anesthetized using one system and the contralateral side was anesthetized using the other, in two separate appointments. Patients assigned anxiety scores on a 5-point scale and used the visual analogue scale (VAS) for pain determination at needle insertion, during delivery of anesthetic solution, immediately after injection, and at the end of the periodontal procedure. Each patient's preference for the delivery system of future injections was also recorded. Results: Patients reported significantly lower anxiety levels with CCLAD compared to the syringe. Significantly lower mean VAS scores for anesthesia deposition, pain immediately after, and at the end of the periodontal procedure were also noted. However, pain at needle insertion was comparable between the two systems, with no statistical significance. Overall, 64.4% patients preferred CCLAD for future anesthesia. Conclusion: Lower pain perceived with CCLAD and higher preference for the system suggest that CCLAD should replace conventional syringes to allow pain-free dental treatment.

Local anesthesia is administered to reduce pain during dental treatments, but may itself cause pain and contribute to increased dental fear. Computer-controlled local anesthetic delivery (CCLAD) is one the method to reduce patient pain during local anesthesia; it is a device that slowly administers anesthetics by using a computerized device to control the injection speed. This literature review aims to provide an objective assessment of the usefulness of CCLAD for controlling pain by reviewing papers published to date that have used CCLAD.

Managing pain and anxiety in patients has always been an essential part of dentistry. To prevent pain, dentists administer local anaesthesia (LA) via a needle injection. Unfortunately, anxiety and fear that arise prior to and/or during injection remains a barrier for many children and adults from receiving dental treatment. There is a constant search for techniques to alleviate the invasive and painful nature of the needle injection. In recent years, researchers have developed alternative methods which enable dental anaesthesia to be less invasive and more patient-friendly. The aim of this review is to highlight the procedures and devices available which may replace the conventional needle-administered local anaesthesia. The most known alternative methods in providing anaesthesia in dentistry are: topical anaesthesia, electronic dental anaesthesia, jet-injectors, iontophoresis, and computerized control local anaesthesia delivery systems. Even though these procedures are well accepted by patients to date, it is the authors' opinion that the effectiveness practicality of such techniques in general dentistry is not without limitations.

This study was carried to identify whether acupuncture at several meridian points can affect the human anesthesia or not using the EEG mapping. We observe the change in the brain wave patterns obtained by electroencephalogram after acupuncture. 1. It is concluded that the pattern of resting computerized EEG map in intact human is normal and acupunctuation at determined meridian points induced lesser narrow field of alpha activity, more extensive field of ${\delta}$, ${\theta}$ activity, father resulted in marked shift to cerebrofrontal dominance in field of ${\delta}$, ${\theta}$ activity by t-SPM. 2. It seems likely that acupunctuation at experimental meridian points acts on slight anesthesia or hypnosis.

The patient was 22-year old male who had been suffered from labored breathing. Computerized tomography, tracheoscopy, tracheogram disclosed tracheal obstruction by external mass compression on Tl level, which ranged 4.Oem in the length and approximately 4mm in diameter on tracheogram. Under the local anesthesia, tracheostomy was done to prevent intraoperative airway obstruction. And general anesthesia, low collar incision 8z extended median sternotomy was made and nearly total thyroidectomy was performed. After the circumferential resection of the obstructed segment approximately 4cm in length[7 tracheal rings], direct end-to-end anastomosis of trachea was performed. Postoperatively, the patient`s neck was maintained in flexion state to reduce tension of anastomotic site. Postoperatively. medical therapy[Comthyroid k Calcium lactate] and radiotherapy were done.

There exist patients complaining speech problem due to dysesthesia or anesthesia following dental surgical procedure accompanied by local anesthesia in clinical setting. However, it is not clear whether sensory problems in orofacial region may have an influence on motor speech abilities. The purpose of this study was to investigate whether transitory sensory impairment of mandibular nerve by local anesthesia may influence on the motor speech abilities and thus to evaluate possibility of distorted motor speech abilities due to dysesthesia of mandibular nerve. The subjects in this study consisted of 7 men and 3 women, whose right inferior alveolar nerve, lingual nerve and long buccal nerve was anesthetized by 1.8 mL lidocaine containing 1:100,000 epinephrine. All the subjects were instructed to self estimate degree of anesthesia on the affected region and speech discomfort with VAS before anesthesia, 30 seconds, 30, 60, 90, 120 and 150 minutes after anesthesia. In order to evaluate speech problems objectively, the words and sentences suggested to be read for testing speech speed, diadochokinetic rate, intonation, tremor and articulation were recorded according to the time and evaluated using a Computerized Speech $Lab^{(R)}$. Articulation was evaluated by a speech language clinician. The results of this study indicated that subjective discomfort of speech and depth of anesthesia was increased with time until 60 minutes after anesthesia and then decreased. Degree of subjective speech discomfort was correlated with depth of anesthesia self estimated by each subject. On the while, there was no significant difference in objective assessment item including speech speed, diadochokinetic rate, intonation and tremor. There was no change in articulation related with anesthesia. Based on the results of this study, it is not thought that sensory impairment of unilateral mandibular nerve deteriorates motor speech abilities in spite of individual's complaint of speech discomfort.

Background: Intraosseous anesthesia is the process by which an anesthetic solution, after penetration of the cortical bone, is directly injected into the spongiosa of the alveolar bone supporting the tooth. This study aimed to compare the effectiveness of the traditional inferior alveolar nerve block (IANB) and computerized intraosseous anesthesia in the surgical extraction of impacted lower third molars, compare their side effects systemically by monitoring heart rate, and assess patients' a posteriori preference of one technique over the other. Methods: Thirty-nine patients with bilaterally impacted third molars participated in this study. Each patient in the sample was both a case and control, where the conventional technique was randomly assigned to one side (group 1) and the alternative method to the contralateral side (group 2). Results: The traditional technique was faster in execution than anesthesia delivered via electronic syringe, which took 3 min to be administered. However, it was necessary to wait for an average of 6 ± 4 min from the execution to achieve the onset of IANB, while the latency of intraosseous anesthesia was zero. Vincent's sign and lingual nerve anesthesia occurred in 100% of cases in group 1. In group 2, Vincent's sign was recorded in 13% of cases and lingual anesthesia in four cases. The average duration of the perceived anesthetic effect was 192 ± 68 min in group 1 and 127 ± 75 min in group 2 (P < 0.001). The difference between the heart rate of group 1 and group 2 was statistically significant. During infiltration in group 1, heartbeat frequency increased by 5 ± 13 beats per minute, while in group 2, it increased by 22 ± 10 beats per minute (P < 0.001). No postoperative complications were reported for either technique. Patients showed a preference of 67% for the alternative technique and 20% for the traditional, and 13% of patients were indifferent. Conclusion: The results identified intraosseous anesthesia as a valid alternative to conventional anesthesia in impacted lower third molar extraction.

Purpose: To study the reliability of intra- and interobserver reliability in angular measurement of hallux valgus deformity by assessing hallux valgus angle (HVA) and the 1st to 2nd intermetatarsal angle (1-2 IMA) through using computerized system. Materials and Methods: 20 cases of moderate to severe hallux valgus patients were included in this study. With the standing anteroposterior view of foot, the HVA and 1-2 IMA were calculated by computerized measurement system of Infinity cooperation, called ${\pi}$-view, with its software tools. Using the statistical software program, SPSS (version 12th), we interpreted the results which were measured by two independent observers. Results: In the intraobserver measurement, the HVA of observer A showed reliability ($32.5^{\circ}{\pm}6.9$ and $33.1^{\circ}{\pm}6.8$)(p<0.05). 1-2 IMA in observer A was not regarded as reliable ($16.9^{\circ}{\pm}2.8$ and $17.1^{\circ}{\pm}2.8$)(p>0.05). In the results of observer B, HVAs were measured as $35.7^{\circ}{\pm}7.6$ and $36.2^{\circ}{\pm}7.7$, and were not reliable (p>0.05). 1-2 IMA in observer B was not reliable as well ($17.0^{\circ}{\pm}0.8$ and $20.8^{\circ}{\pm}1.5$)(p>0.05). In the interobservers' measurements, the first and the second results of HVA were $3.2^{\circ}{\pm}3.6$ and $3.1^{\circ}{\pm}3.1$, reliable within the 95% confidence interval (p<0.05). 1-2 IMAs were $0.1^{\circ}{\pm}1.9$ and $3.73^{\circ}{\pm}1.3$, which were not reliable (p>0.05). Conclusion: In the angular measurement of the hallux valgus by computerized system, the HVA and 1-2 IMA showed less error range in the interobserver's results, compared with the previous studies about the manual measurement. However, our results failed to show the statistical reliability of intra- and interobserver's measuring. Therefore, even the computerized angular measurements in the severity of hallux valgus require development of the measuring methods and software tools.
