Invasive dental procedures can be performed only with local anesthesia; in some cases, it may be useful to combine the administration of drugs to obtain anxiolysis with local anesthesia. Sedation required level should be individually adjusted to achieve a proper balance between the needs of the patient, the operator, and the safety of the procedure. Surgical time is an important factor for post-operative phases, and this could be greatly increased by whether the patient interrupts the surgeon or if it is not collaborative. In this manuscript some dentistry-used methods to practice conscious sedation have been evaluated. This manuscript could be a useful reading on the current state of conscious sedation in dentistry and an important starting point for future perspectives. Surely the search for safer drugs for our patients could have beneficial effects for them and for the clinicians.

Review
Various techniques have been explored to prolong the duration and improve the efficacy of local anaesthetic nerve blocks. Some of these involve mixing local anaesthetics or adding adjuncts. We did a literature review of studies published between 01 May 2011 and 01 May 2021 that studied specific combinations of local anaesthetics and adjuncts. The rationale behind mixing long- and short-acting local anaesthetics to hasten onset and extend duration is flawed on pharmacokinetic principles. Most local anaesthetic adjuncts are not licensed for use in this manner and the consequences of untested admixtures and adjuncts range from making the solution ineffective to potential harm. Pharmaceutical compatibility needs to be established before administration. The compatibility of drugs from the same class cannot be inferred and each admixture requires individual review. Precipitation on mixing (steroids, non-steroidal anti-inflammatory drugs) and subsequent embolisation can lead to serious adverse events, although these are rare. The additive itself or its preservative can have neurotoxic (adrenaline, midazolam) and/or chondrotoxic properties (non-steroidal anti-inflammatory drugs). The prolongation of block may occur at the expense of motor block quality (ketamine) or block onset (magnesium). Adverse effects for some adjuncts appear to be dose-dependent and recommendations concerning optimal dosing are lacking. An important confounding factor is whether studies used systemic administration of the adjunct as a control to accurately identify an additional benefit of perineural administration. The challenge of how best to prolong block duration while minimising adverse events remains a topic of interest with further research required.

Review
The most widely used medications in dentistry are local anesthetics (LA), especially lidocaine, and the number of recorded adverse allergic responses, particularly of hazardous responses, is quite low. However, allergic reactions can range from moderate to life-threatening, requiring rapid diagnosis and treatment. This article serves as a review to provide information on LA, their adverse reactions, causes, and management.

Review
PURPOSE
To evaluate the evidence supporting effects and adverse effects of local analgesia using different pharmacological agents and injection techniques during dental treatment in children and adolescents aged 3-19 years.
METHODS
A systematic literature search of databases including PubMed, Cochrane, and Scopus was conducted in November 2016. The PRISMA-statement was followed. Two review authors independently assessed the selected randomised control trials for risk of bias and quality.
RESULTS
725 scientific papers were identified. 89 papers were identified to be read in full text of which 80 were excluded. Finally, 9 papers were evaluated for quality and risk of bias. Many of the included papers had methodological shortcomings affecting the possibility to draw conclusions. Information about ethical clearance and consent were missing in some of the included papers. No alarming adverse effects were identified. One study was assessed as having low risk of bias. This reported inferior alveolar nerve block to be more effective than buccal infiltration for dental treatment of mandibular molars, while no differences were found regarding pharmacological agents.
CONCLUSIONS
At present, there is insufficient evidence in support of any pharmacologic agent or injection technique as being superior compared to others. There is a need for more rigorous studies which also handle the ethical issues of including children in potentially painful studies.

Randomized Controlled Trial
BACKGROUND
Different distraction techniques have been used in dentistry and have shown great results in managing anxious pediatric patients specially during local anesthesia administration. One of the recently invented techniques is virtual reality. The purpose of the study was to evaluate the effect of virtual reality distraction on anxiety and pain during buccal infiltration anesthesia in pediatric patients.
METHODS
Healthy, cooperative 6- to 12-year-old children requiring buccal infiltration anesthesia were randomly assigned to a test or control group. In the test group, local anesthesia was administered while the subjects were watching a cartoon video using virtual reality goggles. Subjects in the control group watched a cartoon video on a screen during the administration of local anesthesia. To assess anxiety in both groups, heart rate was recorded using a pulse oximeter at five time points: (1) once the subject sets on the dental chair as a baseline; (2) when video is on; (3) at topical anesthesia application; (4) during needle insertion; (5) after the administration of local anesthesia. The face, legs, activity, cry, consolability (FLACC) behavioral pain assessment scale and the Wong-Baker FACES pain rating scale were used to assess pain.
RESULTS
A total of 50 subjects were included with a mean age of 8.4 ± 1.46 years. Twenty-nine (58.0%) of the subjects were females. The mean heart rate at all time points except baseline was significantly higher among the test group compared to the control group. Multiple regression analysis showed that younger subjects and females had higher mean FLACC behavioral pain assessment scale scores (P = 0.034 and P = 0.004, respectively) regardless of the distraction technique used. Younger subjects and subjects with higher baseline heart rate reported higher mean Wong-Baker FACES pain rating scale score (P = 0.031 and P = 0.010, respectively), controlling for all other variables.
CONCLUSION
Female subjects and the younger age group were more likely to report higher pain scores during local anesthesia administration regardless of the type of distraction used.

Reliable analgesia can nowadays be achieved with several techniques and different anesthetic solutions, but side effects may be encountered. Severe and potentially fatal cardiovascular reactions can be the result of an intravascular injection. An easy to use, effective and safe alternative is the periodontal ligament injection. Nerve damage or cardiovascular side effects are not to be expected. This type of anesthesia can be of advantage for many dental procedures. With new devices like the computer-controlled local anesthetic delivery system, the periodontal ligament injection is a convenient way of local anesthesia for both patient and dentist.

Review
Using local anaesthetics in daily practice, particularly by anaesthetists and dentists, is connected with the risk of side effects. Therefore, the observation of side effects, carrying out detailed research (according to the chart proposed in this study) and conducting specialist examinations is of the highest importance. There is a variety of side effects that could occur during local anaesthesia procedures, with the intensity ranging from clinically unimportant to life threatening. Clinicians' major concerns are the appearance of various hypersensitivity reactions, including anaphylaxis. Healthcare providers responsible for the administration of local anaesthetics should be able to detect hypersensitivity reactions to implement appropriate treatment and then choose highly selected diagnostic procedures. The final diagnosis should be based on specific medical history; documentation, including a description of the case and measurement of tryptase activity; skin tests; and provocation trials. Screening tests are not recommended in populations without hypersensitivity to local anaesthestics in their medical history.

An injectable local anesthetic producing repeatable on-demand nerve block would be desirable for pain management. Here we present a phototriggerable device to achieve repeatable and adjustable on-demand local anesthesia in superficial or deep tissues, consisting of gold nanorods attached to low temperature sensitive liposomes (LTSL). The particles were loaded with tetrodotoxin and dexmedetomidine. Near-infrared light (NIR, 808 nm, continuous wave) could heat gold nanorods at low fluence (short duration and low irradiance), leading to rapid release of payload. In vivo, 1-2 min of irradiation at ≤272 mW/cm produced repeatable and adjustable on-demand infiltration anesthesia or sciatic nerve blockade with minimal toxicity. The nerve block intensity and duration correlated with the irradiance and duration of the applied light.

In order to solve the nursing problems of local anesthesia patients under arthroscopy, a nursing method and experience based on local anesthesia patients under arthroscopy was proposed. From June 2019 to May 2021, 478 patients who underwent knee arthroscopy under spinal anesthesia or local anesthesia were retrospectively investigated, including 186 cases (38.9%) under local anesthesia and 292 cases (61.1%) under spinal anesthesia. 2% lidocaine plus epinephrine was injected locally and intra-articular in patients with local anesthesia, and 0.75% bupivacaine in patients with spinal anesthesia. It was found that in the local anesthesia group and spinal anesthesia group, 94.1% (175/186) and 98.3% (287/292) patients did not feel pain during operation. 93.0% (173/186 cases) and 96.2% (281/292 cases) of patients in the two groups were satisfied or very satisfied with the effect of anesthesia, respectively. The experimental results showed that local anesthesia was a simple and effective anesthesia method for knee arthroscopy, which was more reliable and safer than spinal anesthesia. Local anesthesia could be used for knee arthroscopy or cleaning and rinsing, free body removal, or even common meniscinoplasty.
