This systematic review and meta‐analysis analysed whether pain and disruptive behaviour can be decreased by the use of computerized local dental anaesthesia (CDLA) in children. The literature was screened to select randomized clinical trials that compared computerized and conventional anaesthesia. The primary outcome was pain perception during anaesthesia; the secondary, disruptive behaviour. The risk of bias of individual papers and the quality of the evidence were evaluated. After search, 8389 records were found and 20 studies remained for the qualitative and quantitative syntheses. High heterogeneity was detected for both outcomes. For the pain perception, the overall analysis showed a standard mean difference of −0.78 (−1.31, −0.25) favouring CDLA; however, when only studies at low risk of bias were analysed (subgroup analysis), there was no difference between the two techniques [−0.12(−0.46, 0.22)]. For disruptive behaviour, no differences were detected for continuous [−0.26 (−0.68, 0.16)] or dichotomous data [0.81 (0.62, 1.06)]. The quality of evidence was judged as low for pain perception and very low for disruptive behaviour. It is concluded that there is no difference in the pain perception and disruptive behaviour in children subjected to computerized or conventional dental local anaesthesia. Notwithstanding, the quality of the available evidence is low.

“…However, the amount of information is a controversial issue as some patients could experience more anxiety due to an excess of that. Computerized controlled anesthetic delivery systems are able to better control the flow and pressure of the liquid which can reduce pain during local anesthesia infiltration (6,17,19). A recent literature review (19) showed that most studies compared conventional dental anesthesia with computerized controlled anesthesia systems in terms of pain, generally obtaining better results in the maxilla for the computerized one, as measured by visual analogue scales, electric pulp tester, dental anxiety scale, or perceived stress scale.…”

Nevertheless, the sound and beeps emitted by The Wand System, the slowness of the anesthetic act and the fact that to observe an unknown anesthetic device could even provoke more fear that a traditional syringe are some unpleasant issues discussed in some studies (10,19).…”

Background: A single-blinded randomized controlled trial among patients requiring an upper third molar extraction was performed to evaluate the anxiety degree after receiving information or not about the functioning of The Wand system. Secondarily, perceived pain and the need of re-anesthesia were assessed. Material and Methods: Patients were randomly assigned to the experimental group (detailed explanation about The Wand) or control group (no specific information). Local anesthesia with The Wand consisted in a supraperiosteal infiltrative technique injection 1.6 mL at the buccal and 0.2 mL at the palatal side. Distinct questionnaires for assessing dental anxiety and 100-mm visual analog scales to assess pain were delivered. Demographic data, radiological parameters, operative time and type of intervention were also registered. A descriptive bivariate analysis by non-parametric tests to detect differences in anxiety, pain and re-anesthesia was performed by SPSS 22.0 (SPPS Inc. Chicago, USA). Results: A total of 85 patients were assessed for eligibility but 17 participants were lost due to the cancellation of the visit for the surgical intervention. Finally, sixty-eight patients were included (34 participants in each group), 47 women (69.1%) and 21 men (30.9%), with an average age of 28.8 (± 9.3) years.

“…This aspect could be particularly beneficial for patients suffering from systemic diseases that require peculiar treatment during local anesthesia. The increased comfort and better patient's acceptance during STA have been extensively documented on pediatric dentistry research (11)(12)(13)(14)(15). Several comparative studies between CLA and conventional injections have been conducted also in periodontology, endodontics, prosthetics, maxillofacial surgery and restorative dentistry (15)(16)(17)(18)(19).…”

SUMMARYObjectives. This prospective cohort study aimed to investigate effectiveness of Computerized Local Anesthesia (CLA) on oral implantology through estimation of pain and discomfort and total quantity of injected anesthetic. Methods. Forty-five consecutive patients whose treatment plan included immediate or late dental implants were included in this study. The main inclusion criteria comprised: previous implant intervention under conventional anesthesia (CA) during the past 3 years and no previous treatment of pain relief. All patients reported on a 0-10 scale on previous experience with CA, and new experience with CLA. The same CLA system, namely Single Tooth Anesthesia (STA) was used for all patients with half of the quantity normally used for CA. Data on quantity of anesthetic and reported ratings were collected and described. Potential associations and determinant variables were analysed through correlation analysis and regression models. Results. Out of 45 patients, 27 received post-extractive implant surgery whereas the rest 18 implant surgery on healed sites. The reported pain from STA (mean 1.6, SD 0.7) showed important difference as compared to CA (7.9, SD 1.2; z=5.873; p<0.0001). The comfort perceived during the STA ranged from 7 to 10 (mean 9.5, SD 0.79). A second injection with half of the initial dose was necessary in three cases only. Conclusions. STA system proved to be effective during interventions of dental implantology, by markedly reducing patients' pain and discomfort and the total quantity of necessary anesthetic.
