“…Studies from the late 1990s showed that patients' pain perception during administration of anesthesia was reduced by dentists’ better speed control in administering the anesthetic agent [ 4 , 5 ]. Likewise recent studies showed a preference for CCLAD over conventional syringe in terms of pain perception during administration and efficacy [ 6 , 7 ]. On the other hand, there are studies that show no significant difference in pain perception when comparing CCLAD with a conventional syringe [ 8 , 9 ].…”

This prospective randomized controlled trial aimed to evaluate and compare patient response to a conventional syringe and a computer-controlled local anesthetic delivery system (CCLAD) both immediately and after reflection time, including the impact of anesthesia duration. Methods: Twenty adult patients (10 men and 10 women) with at least two tooth-neck defects each in different quadrants were treated with local buccal infiltration anesthesia. Using split-mouth design, one quadrant was anesthetized using a conventional syringe, the other with CCLAD. The time elapsed between time of injection and time of disappearance of numbness was recorded. Patients were asked to mark on a Visual Analog Scale their visual impression of the device regarding anxiety-inducement, their sensation of mucosal puncture, pain during administration, and pain perception during treatment for the two different methods as well as future preference immediately after treatment and after reflection time. Results: The level of anxiety-inducement and pain during administration were ranked three times higher with the conventional syringe (35.95%-11.85%, p < 0.001 and 21.3%-7.7%, p ¼ 0.005, respectively). There was no difference in mean sensation of mucosal puncture, nor a statistically significant correlation between duration of administration and time until disappearance of numbness. Once anesthesia was administered, no pain during treatment was detected using either method. Patients' preference of methods changed significantly with time in favor of CCLAD (p ¼ 0.01). Conclusions: The use of CCLAD increased patients' comfort visually and in terms of administration; patients' preference in favor of CCLAD increased with time. Clinical significance: Patients' preference of CCLAD over against the conventional syringe, even more so after reflection time, can imply the preference of CCLAD for clinicians, too, in order to enhance patients' and clinicians' comfort.

“…The heterogeneity was I2=91%, hence we applied the random effects model for analysis. (Figure 1) 18 This systematic review and meta-analysis aimed to assess the effect of alternative anesthesia techniques in reducing pain as compared to conventional technique in patients undergoing dental treatment or retreatment.

Aim: To assess and summarize effect of computerized anesthesia techniques in reducing pain as compared to conventional technique in adult patients undergoing dental treatment. We conducted a comprehensive Methods: literature search on four electronic databases, PubMed, net of information, google scholar, and Cochrane library for this systematic review after registering with Prospero. The inclusion and exclusion was stringent to conduct the filtering and select the Randomised Control Trial/ Clinical Trial which were eligible for qualitative and subsequent quantitative analysis. The heterogeneity was analyzed with the I2 values and risk of bias was conducted with appropriate tool form Cochrane. Review Manager 5.3 was used for meta-analysis. Out of 24 studies, 08 studies were further Results: included for quantitative analysis and the meta-analysis was interpreted with the forest plot. The outcome which we assessed was the pain outcome after anaesthesia. The mean cumulative difference was -1.73 (CI: -3.01to -0.45). The heterogeneity was I2=91%, hence we applied the random effects model for analysis. The CCLAD seems to be a promising Conclusion: device, offering a less painful method of anaesthesia administration; which showed that the pain was higher in conventional group when compared to other interventional techniques.

“…As a result, varied techniques have been utilized to reduce patients' paininduced fear and anxiety, such as low-level laser therapy, superficial anesthesia, music therapy, psychosomatic methods, cold therapy of soft tissues, distracting techniques, employment of fine needles, computer-controlled local anesthetic delivery technique, and jet injection. However, all of these techniques have some restrictions and, therefore, they need to be superseded by more suitable approaches for pain reduction [2][3][4][5][6][7][8][9][10][11]. Inferior alveolar nerve block (IANB) has been widely used for the anesthesia of mandibular molar and premolar teeth during various dental procedures.…”

Background. The ability to control pain is an essential part of dental procedures and the need for optimal pain control and reduction of discomfort is the primary concern of every dentist. This study aims to compare the pain and vital signs during inferior alveolar nerve block between conventional and a new modification of the two-step injection techniques. Methods. In this institutional single-blind randomized clinical trial, attendees of dental school at Mazandaran University of Medical Sciences from February to May 2022 were included. Inclusion criteria were 20–60 years old and healthy (ASA1) individuals who were willing to participate in this study. Individuals who were taking medications affecting their understanding of pain and patients with active infections at the injection site were excluded. These individuals were divided into two groups. First, superficial anesthesia was performed and afterward, conventional and two-step injection techniques were performed. For the two-step injection method, 6 mm of the needle was injected into the mucosa and one-third of the local anesthetic solution was released from the computer-controlled injection toolkit. Afterward, a 25 mm 30-gauge needle was reinserted into the previous hole delivering the remaining local anesthetic. The pain during injection was measured by a patient-reported numerical rating scale (NRS). Moreover, vital signs were monitored immediately before and after the injection. Kolmogorov–Smirnov test, Mann–Whitney U test, independent T-test, and Fisher’s exact χ2 test were performed for statistical analysis (α = 0.05). Results. This study involved 32 adults aged between 20 and 50 years old with 1 : 1 female/male sex distribution. The pain score was significantly higher in the conventional injection technique compared to the two-step injection technique in all sex and age groups. There were no significant differences in vital signs between the conventional and two-step injection techniques. There was no significant difference in the mean pain scores of females and males, regardless of their injection techniques. Conclusion. Utilizing the two-step injection technique in patients for inferior alveolar block reduces pain during injection without altering patients’ vital signs significantly. This trial is registered with IRCT20220106053646N1.
