RESUMEN
BACKGROUND: Local anesthetic puncture is often related to the experience of pain. This study aimed to systematically analyze the literature on changes in pain perception during the anesthetic puncture of dental local anesthesia after Photobiomodulation Therapy (PBMT). MATERIAL AND METHODS: An electronic search was performed in eight primary databases (Embase, LILACS, BBO, LIVIVO, MedLine via PubMed, SciELO, Scopus, and Web of Science) and three additional ones (EASY, Google Scholar, and OATD) to partially capture the "gray literature". The PICO strategy was used to identify randomized clinical trials evaluating the analgesic effect of PBMT in the anesthetic puncture site of dental local anesthesia compared to placebo or control groups, without restrictions on publication language and year. Two reviewers extracted the data and assessed the individual risk of bias of the eligible studies using the Cochrane Collaboration Risk of Bias Tool version 2.0. RESULTS: The electronic search found 3,485 records, of which eight met the eligibility criteria and were included in the qualitative synthesis. The studies were published from 2011 to 2022. None of the included studies had a low risk of bias. PBMT groups showed no significant difference in pain scores compared to placebo and control groups of most studies. CONCLUSION: Based on a low to very low certainty of evidence, PBMT seems to have no effect on pain perception during anesthetic puncture in patients undergoing dental local anesthesia.

OBJECTIVES: The absolute necessity of a palatal injection for the extraction of primary maxillary molars has never been explored, despite the fact that it is widely known that children do not tolerate local anesthetic injections into the palatal tissue well. The aim of this study was to compare separately the perception of pain in the absence of palatal injection after anesthesia and maxillary primary molar tooth extraction using different anesthetic solutions and different post-anesthetic waiting times. MATERIALS AND METHODS: A single-blinded randomized controlled study was conducted in 78 participants (26 patients with palatal anesthesia (the control groups), and 26 patients with 5 min and 26 patients with 8 min post-anesthetic waiting time without palatal anesthesia (the study groups)). Subjective experiences of pain were evaluated separately after anesthesia and tooth extraction using the Visual Analog Scale (VAS) and the Wong-Baker Faces Pain Rating Scale (WBS). RESULTS: In terms of VAS scores obtained following administration of anesthesia, there was a statistically significant difference between the groups (p<0.05). VAS pain scores were reported to be lower in the groups without palatal anesthesia than in the groups with palatal anesthesia. No statistically significant difference was observed in VAS and Wong-Baker scores after tooth extraction between the groups with and without palatal anesthesia (P>0.05). CONCLUSIONS: While the pain reported following administration of anesthesia was found to be higher in the groups receiving palatal anesthesia, no difference was found between the groups in the pain reported after tooth extraction. CLINICAL RELEVANCE: Extraction of maxillary primary molars is possible without palatal injection by injecting 4% articaine or 2% lidocaine into the buccal vestibule of the tooth with a waiting time of 5 or 8 min.

Adverse reactions to dental local anaesthetics are fortunately rare. However, when they occur, they can be severe and debilitating to the patient. Adverse reactions may be either prolonged anaesthesia, with or without dysaesthesia, or systemic reactions. Although these systemic reactions are commonly thought to be allergies, this is rarely the case. Much more commonly, these adverse systemic reactions are either cardiovascular or from the central nervous system. This paper describes two contrasting cases of functional neurologic disorder which illustrates the consequences and appropriate management. The responsibilities of the dentist who injected the local anaesthetic are outlined.

The study herein evaluated the effects of infiltrative anesthesia administered via different ways. Resultantly, the pain and anxiety were monitored using psychometric, physiological and biochemical methods. Sixty children aged 7-11 years (8.73 ± 1.38) were included in the study. They were divided into 2 groups (n = 30): Traditional injection (control group), and computer controlled local analgesic delivery (CCLAD) (study group). Pulse, oxygen saturation (SpO2), and salivary cortisol levels were recorded, and the scales data (Visual Analogue Scale (VAS), Wong-Baker Faces Rating Pain Scale (WBS), Modified Child Dental Anxiety Scale (MCDAS) and Face, Leg, Activity, Cry, Consolability Behavioral Pain Assessment Scale (FLACC)) were evaluated. The data were statistically analyzed. Age and gender had not much impact on the measured parameters (p > 0.05). SpO2 values in both groups were not significantly different (p > 0.05). Pulse, VAS, WBS, MCDAS, FLACC and salivary cortisol values were increased after the anesthesia in control group (p < 0.05). WBS, MCDAS, FLACC and salivary cortisol values were decreased after the anesthesia in study group compared to the control (p < 0.05). It was inferred that computer controlled local analgesic delivery system could be preferred in pediatric patients because of reduced pain and anxiety.

INTRODUCTION: Previous studies on intraosseous (IO) anesthesia as a primary injection have shown high success rates. The TuttleNumbNow (TNN; Orem, UT) is a new primary IO injection technique that has not been scientifically evaluated. Therefore, the purpose of this prospective randomized, crossover study was to evaluate the anesthetic efficacy of the TNN IO technique using the Septoject Evolution needle (Septodont, Saint-Maur-des-Fosses, France) compared with buccal infiltration for pulpal anesthesia in mandibular first molars. METHODS: One hundred four healthy subjects were randomly assigned to 2 treatment groups separated by at least 2 weeks. One set of injections consisted of buccal infiltration of the mandibular first molar using 1.8 mL 4% articaine with 1:100,000 epinephrine followed by a mock TNN injection distal to the mandibular first molar. The other set of injections was a mock buccal infiltration of the mandibular first molar followed by a TNN injection of 1.8 mL 4% articaine with 1:100,000 epinephrine distal to the mandibular first molar. Statistical analyses were performed. RESULTS: For the mandibular first molar, which had a 42% anesthetic success rate (highest 80 reading) with buccal infiltration compared with 49% with the TNN, no statistically significant difference in success was observed (P = .2115). CONCLUSIONS: The TNN technique has been advocated as an IO injection. However, the inability to deliver anesthetic solution to the cancellous bone resulted in an anesthetic success rate of 49%. The success was statistically similar to a buccal infiltration (42%) and would not provide adequate pulpal anesthesia as a primary injection.

OBJECTIVES: Fear of pain in dentistry especially the injection involved in most of the processes has always been an important issue preventing the patients from consulting a dentist at the right time. This study aims to evaluate the effect of photobiomodulation therapy on reduction of pain in infiltration injection. MATERIALS AND METHODS: This trial is a crossover study including 30 patients. The patients are divided into two groups (laser therapy in the first period and placebo effect in the next period or vice versa with split-mouth design) using the covariate adaptive randomization method. All the patients received bilateral maxillary canine anesthesia in two periods performed with an ICT injection device (amount of anesthesia solution loaded: 1.8 mL) at a speed of 1 mL/min and a temperature of the solution of 37 °C. In each period, patients received either a prophylactic dose of 940-nm laser (500 mW, 10 J/cm2) or its placebo effect before the injection. The degree of pain perception after each sort of treatment is evaluated by both SEM (Sound, Eye, Motor, and Pain) and VAS (Visual Analogue Scale) scales. RESULTS: According to analysis, all the patients scored a VAS scale under 3 in the period they received intervention. Also considering the SEM scale, most of the patients scored 0 in the intervention period. No adverse effect was reported during or after the process. CONCLUSIONS: The study showed a significant effect of photobiomodulation on reducing pain perception during infiltration injection. CLINICAL RELEVANCE: This method can be useful in order to lower the pain for the patients consulting a dentist and therefore facilitate consulting at early stages of the dental issues. TRIAL REGISTRATION: The registration number (date) of the clinical trial in a Primary Registry in the WHO Registry Network is IR.ARAKMU.REC.1398.248(13/03/2020).

BACKGROUND: Local anesthesia is an essential component of dentistry, but there is limited quantifiable understanding of what techniques and local anesthetic solutions are used by practicing dentists. Use of the local anesthetic articaine has been highly debated in dentistry regarding its efficacy and risks for paresthesia. The aims of this study were to expand the knowledge of local anesthesia practices of dentists in the United States through a large-scale survey and associate potential influencing factors regarding articaine use specifically. METHODS: The 23-item survey was sent to 10,340 practicing dentists in the United States, gathering demographic data and local anesthesia approaches and concerns. Statistical analysis consisted of descriptive, bivariate, and multivariate logistic regression analyses. RESULTS: A total of 1,128 dentists completed the survey. Previous experience with articaine was reported by 97.6% of respondents, with 3.3% no longer using articaine. Sixty percent of respondents indicated using articaine for most local anesthetic injections administered. Multivariable regression analysis found those reporting to use articaine for all local anesthetic injections involving vasoconstrictors were more likely to be male (odds ratio, 1.59; P = .002) or general dentists (odds ratio, 1.63; P < .001). CONCLUSIONS: Articaine has a perceived benefit to practitioners as most respondents reported using articaine as their primary local anesthetic. A practitioner's sex and type were found to affect the profile of use of articaine. PRACTICAL IMPLICATIONS: Assembling evidenced-based local anesthesia practices would be beneficial to ensure US practitioners are more standardized in administering local anesthetics, particularly articaine, in the safest and most efficacious way.

OBJECTIVE: The purpose of this prospective, randomized crossover study was to compare the peak incidence of success, onset, and incidence over time of pulpal anesthesia in maxillary first molars following a buccal infiltration of 1.8 mL or 3.6 mL of 4% articaine with 1:100 000 epinephrine. METHODS: A total of 118 adults received 1.8 mL or 3.6 mL of 4% articaine with 1:100 000 epinephrine via buccal infiltration of the maxillary first molar at 2 separate appointments. Electric pulp testing (EPT) of the maxillary first molar was performed over 68 minutes. RESULTS: There was no significant difference in the peak incidence of anesthetic success (85% and 92%, respectively) in the maxillary first molar between 1.8 mL and 3.6 mL. The difference in onset times (4.5 min for 1.8 mL vs 4.4 min for 3.6 mL) was not statistically significant. However, the 3.6-mL volume did produce a significantly higher incidence of pulpal anesthesia from minutes 48 to 68 compared with the 1.8-mL volume. CONCLUSION: There was no significant difference in peak incidence or onset of pulpal anesthesia in the maxillary first molar between 1.8 mL and 3.6 mL of articaine with epinephrine. The incidence of pulpal anesthesia was significantly higher with 3.6 mL of articaine at 48 minutes and beyond, but neither volume provided complete pulpal anesthesia for all subjects that lasted at least 60 minutes.

Background: The idea of receiving local anesthesia (LA) via an injection is a major source of dental fear and anxiety. In children, dental anxiety is considered the main reason for avoiding dental treatments. Moreover, there are potential complications during/after LA administration. Thus, it is necessary to search for painless, low-risk, and nonpharmacological anesthetic approaches. Aim: This study was performed to evaluate the effectiveness of photobiomodulation (PBM) therapy as an alternative method to LA injection for conventional restorative treatments in pediatric patients. Settings and Design: This was a split-mouth randomized clinical study. Materials and Methods: The study included 15 children between 6 and 12 years old. Each child had 2 similar contralateral caries lesions in the first permanent molars in the same jaw, total (30) teeth. For each child, one tooth was treated under conventional LA injection and the other was treated under PBM-based anesthesia. The Wong-Baker's Faces Pain Scale was used for reporting the pain and discomfort levels at the end of the treatments. Statistical Analysis: Data statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 20. Mann-Whitney U-test was used to compare between the groups. Results: The PBM-based anesthesia group recorded a mean pain score of 2.27 ± 1.28. The conventional LA group recorded a mean pain score of 1.73 ± 0.7. The difference between the groups was not statistically significant (P = 0.168). Conclusions: PBM-based anesthesia may be an optional alternative to LA injection for conventional restorative treatments in children with dental anxiety, needle phobia, or special needs, and it deserves further studies and improvement.

Background: The primary maxillary molars occasionally remain sensitive during operative procedures even post the buccal supraperiosteal injection. This could be due to the widely flared palatal roots receiving accessory innervation from the palatal nerves. Identifying inadequate anesthesia upfront using the electric pulp test (EPT) would give vital information to the clinician on the need of a supplemental palatal injection. Aim: The aim of this study was to assess and evaluate the reliability of the EPT as an indicator of pulpal anesthesia in primary maxillary molars. Methodology: Fifty one primary maxillary molars were subjected to the EPT following a buccal supraperiosteal injection. During the operative procedure, the " Face Legs Activity Cry Consolability" (FLACC) scores were recorded. The outcome of the EPT was correlated with the results of the FLACC score using Pearson's Chi-square test.Results: The EPT results were correlated to the FLACC scores. Five out of the 10 primary maxillary second molars which responded to the EPT scored 0 on the FLACC scale. The remaining 5 teeth scored 1 on the FLACC scale. The P value was 0.056 which was not statistically significant. This infers that the EPT is not a reliable tool to assess the adequacy of pulpal anesthesia in primary maxillary second molars. Conclusion: From the results of the present study, it can be concluded that the EPT is not a reliable tool to be used as an indicator of pulpal anesthesia in primary maxillary molars.

The aim of this study was to clarify or determine any possible association between pain reports with a visual analogue scale (VAS) and a figures based scale. This research was a preliminary study aimed at developing a new pain scale without any verbal description. Healthy Japanese patients aged 20 to 39 years who received anesthetic injections for mandibular third molar extraction at our department were enrolled. Regarding pain from dental local anesthetic injections, we recorded figures selected by participants (among options of a circle, triangle, square, bar, and cross), and VAS scores. Overall, 29 men and 31 women participated in the study. Pain caused by local dental anesthesia tended to remind both men and women of the triangle among the suggested figures. Furthermore, patients who chose a cross also reported higher VAS scores than those who chose other figures. Acute pain caused by local dental anesthesia was associated with triangles, and patients who selected a cross were associated with higher VAS scores. The results of this study provide clinicians with important information for dental practice, and could prove useful in developing new pain scales.

insulin syringe for anesthetizing primary maxillary teeth in children aged 4-9 years. Materials and Methods: This randomized clinical study included 46 children aged 4-9 years. The patients were digitally allotted to receive 4% articaine for extractions of primary maxillary teeth, either using needleless device INJEX or insulin syringe on each side of the maxillary arch, in two different appointments after a 1-week washout period. Pain perception was measured by the subjective (Faces Pain Scale-Revised [FPS-R]) and objective pain scores (Face, Legs, Activity, Cry, and Consolability [FLACC]) and hemodynamic parameters (heart rate and oxygen saturation) during LA administration and during extractions. After the second appointment, children were asked about their preference between needleless device INJEX and insulin syringe. Results: On evaluating subjective pain scores with FPS-R, intergroup differences between the INJEX and insulin syringe groups were found statistically insignificant, both during LA administration (P = 0.101) and extraction (P = 0.080). However, on assessing pain objectively during extraction using FLACC, the mean pain score was less with insulin syringe (2.78) as compared to INJEX (4.72) and the difference was statistically significant (P = 0.000). There was no significant difference in patient preference between the two methods. Conclusion: Pain perception was minimal during local anesthesia administration using needleless device INJEX; however, its clinical efficacy during extractions was reported to be lower than insulin syringe. Background: Managing pain in children is the most challenging task as it forms the foundation for instilling positive behavior toward dental treatment. Adequate local anesthesia (LA) is the cornerstone of pain management. However, the fear of needles, particularly in young children, can result in complete avoidance and refusal of treatment. Aim: This study aimed to evaluate and compare the efficacy and preference between needleless device INJEX and.

PURPOSE: The current study compares articaine 4% with lidocaine 2% in terms of injection pain and effectiveness of anesthesia when treating permanent mandibular first molars (PMFMs) affected by molar incisor hypomineralization (MIH). In addition to comparing the complications of local anesthesia for both solutions. METHODS: The sample included 20 children. Each child was randomly assigned to either articaine 4% or lidocaine 2% in their first session with the other solution being used at the subsequent session. Injection pain and the effectiveness of anesthesia were assessed using the Wong-Baker Faces® Pain Rating Scale and the Face, Legs, Activity, Cry, and Consolability (FLACC) scale. Parents were asked to report any complications of local anesthesia. The Wilcoxon-matched pairs signed-rank test was used to analyze the data. RESULTS: Patients experienced greater pain when receiving articaine 4% injections according to both scales, differences were statistically significant when using the Wong-Baker Faces® Pain Rating scale (p < 0.05). Whereas, the FLACC scale did not show such differences (P > 0.05). Although there were no significant differences between the two solutions regarding the effectiveness of local anesthesia according to both scales (P > 0.05), articaine 4% was clinically found to be more effective than lidocaine 2%. No complications of local anesthesia were reported. CONCLUSIONS: Articaine 4% injection was more painful than lidocaine 2%. However, both solutions were effective in anesthetizing PMFMs affected by MIH and without anesthetic complications in the studied sample.

Photobiomodulation (PBM) has gained increasing interest due to its effectiveness in pain reduction in various fields of dentistry. However, the number of studies evaluating the effect of PBM on injection pain in children is very limited. The aim of the study was to evaluate the efficacy of PBM with three different application parameters (doses) + topical anesthesia on reducing injection pain and to compare these results with the placebo PBM + topical anesthesia in children during supraperiosteal anesthesia administration. 160 children were randomly divided into 4 groups, 3 experimental and 1 control, with 40 subjects in each. In the experimental groups, before the anesthesia administration, PBM with a power of 0.3 W was applied for 20, 30 and 40 s in groups 1, 2 and 3, respectively. In group 4, a placebo application of laser was performed. The pain felt during the injection was assessed using the Wong-Baker Faces Pain Rating Scale (PRS), and also the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Statistical analyses were performed to evaluate the data (p < 0.05). The mean FLACC Scale pain scores were 3.02 ± 2.93, 2.92 ± 2.54, 2.12 ± 1.89 and 1.77 ± 1.90 for the placebo group, and Groups 1, 2, and 3, respectively. Furthermore, the mean PRS scores were 1 ± 1.03, 0.95 ± 0.98, 0.80 ± 0.822 and 0.65 ± 0.921 for the placebo group, and Groups 1, 2 and 3, respectively. The "no pain response" rate was higher in Group 3 as compared to Groups 1, 2, and placebo according to the FLACC Scale and PRS; however, no difference was found between the groups (p = 0.109, p = 0.317). Injection pain in children did not differ with placebo and PBM applied with a power of 0.3 W for 20, 30 and 40 s.

OBJECTIVE: The aim of this study is to evaluate the effect of using anti-stress balls in reducing patients' pain during injection of the inferior alveolar nerve block (IANB). MATERIALS AND METHODS: In this randomized clinical trial, 32 individuals were divided into two groups. The conventional method of anesthesia injection was performed using IANB conventional injection technique. During the injection, individuals in the anti-stress ball group were asked to use the anti-stress ball as a distraction technique. For the control group, no supersede methods were used for pain control. Finally, both groups were asked to record their pain utilizing the numerical rating scale (NRS). The participants' vital signs were monitored before and after injection. Kolmogorov-Smirnov test, independent T-test, and Fisher's exact chi-square test were performed for statistical analysis (α = 0.05). RESULTS: Sixteen females and 16 males in the age range of 40 to 20 years old participated in this study. The mean pain score in the anti-stress ball group was significantly lower (p < 0.001). In both sexes, the pain score in the anti-stress ball group was significantly lower (males p < 0.001 and females p = 0.001). In addition, in all age ranges, the pain score in the control group was higher except for the above 35 years old participants (p = 0.078). Moreover, there were no significant differences in individuals' vital signs (p > 0.05). CONCLUSION AND CLINICAL RELEVANCE: Utilizing an anti-stress ball reduces patients' pain significantly during IANB in both sexes and individuals who are below 35 years without changing vital signs.

PURPOSE: To compare pain perception associated with two computer-controlled local anesthesia devices, the WAND™ STA (Milestone Scientific Inc., Livingston, NJ, USA) and the Calaject (Rønvig dental MFG, Daugaard, Denmark) in young children. METHODS: A split-mouth randomized clinical trial comprising 30 patients, aged 6-12 years, received randomly, in two separate sessions, a local anesthesia injection in the maxillary using either the wand STA or the Calaject. Pain perception was evaluated using the patient's heart rate, an 11-point numerical scale (NRS), and the Sound, Eye, and Motor (SEM) body movements. Statistical difference was set at p = 0.05. Repeated measures analysis of variance were conducted to compare the mean pulse for Calaject and STA at different times. It was followed by univariate analysis and Bonferroni multiple comparisons tests. Wilcoxon tests were performed to compare NRS, SEM, and injection duration between Calaject and STA. RESULTS: There was no significant statistical difference between Calaject and STA in pulse rate before injection (p = 0.720), during injection (p = 0.767), and after injection (p = 0.757). The mean NRS score was significantly greater with STA in comparison with Calaject (p = 0.017). The mean SEM score was also significantly greater with STA in comparison with Calaject (p = 0.002). However, the mean duration was significantly longer with Calaject (p = 0.001). CONCLUSIONS: Calaject was more effective than STA in reducing pain perception associated with periapical injection in young children.

Local anesthesia is performed in dentistry before clinical procedures to avoid pain. Children can show fear at the sight of the needle and pain at its insertion. To make local anesthesia more comfortable, the use of computer-controlled local anesthetic delivery (CCLAD) systems has been developed to control the flow rate of the anesthetic solution injected through the needle. The aim of the present research is to evaluate and compare the discomfort felt by patients using a traditional syringe and the CCLAD system SleeperOne®, by considering pain, size sensation, bitterness, and vomit. 30 patients were included in the study and randomly assigned to traditional anesthesia or CCLAD. After injection, patients were assessed for the abovementioned outcomes. A Visual Analogue Scale (VAS) from 0 to 10 scores was used. As far as pain is concerned, statistically lower mean values were found in the Trial group (p < 0.05). Instead, concerning size, bitterness and vomit perceptions, no statistically significant differences were found between the groups (p > 0.05). Linear regressions were calculated considering technique, quadrant, dental arch, tooth, dentition, sex, and age as independent variables. The technique has shown to have a significant influence on pain (p < 0.05), with lower values for SleeperOne® device. Pain resulted significantly influenced by the type of dentition (p < 0.05), with higher scores for deciduous one. Moreover, perceived pain decreased with the increase of the age of patients (p < 0.05). At last, bitterness perception scores resulted to be higher for primary first molars (p < 0.05). SleeperOne® device seems to be a valid support for the reduction of pain related to anesthetic injection, especially in children. Further studies should evaluate CCLADs' uses combined with lidocaine preanesthetic as well as with conscious sedation through nitrous oxide in order to determine possible synergistic effects between these procedures.

BACKGROUND: Facial Hemangiomas are often recommended to be removed exclusively in the operating room under general anesthesia, especially for children under the age of 4. Assumed parental and patient anxiety and possible blood loss pushes surgeons away from attempting excision under local anesthesia. METHODS: A review was conducted to assess the outcomes of children who underwent excision of facial hemangiomas under local anesthesia alone by 1 plastic surgeon with a minimum of 3 months follow-up. Complications and hemangioma recurrence were recorded. A survey was given 3 to 6 months after treatment to assess parental satisfaction, anxiety, and thought process about anesthesia. RESULTS: Eighteen children (9 males and 9 females) underwent in-office excision between 2020 and 2021. The mean age of this cohort was 12 months ( ranging 2-52 m). The average facial hemangioma size was 2.088 cm (ranging 1.0-3.2 cm). Ten patients experienced complete resolution (56%) at 12-month follow-up. There were no hospitalizations or cases of significant (>10 mL) blood loss, infection, dehiscence, hematoma, or scar hypertrophy. The average level of parental anxiety before the procedure was 3.3/10, and 1.6/10 after the procedure. Total 13/14 parents gave 4/4 ratings for satisfaction with the quality of care, team responsiveness, pain management, and management of expectations. CONCLUSIONS: Facial hemangioma removal under local anesthesia alone is a safe and feasible alternative treatment method for patients younger than 4 years of age.
