Efficacy of QuickSleeper Intraosseous Injection of 4% Articaine in Mandibular First Molars With Symptomatic Irreversible Pulpitis: A Randomized Controlled Trial.

To evaluate the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine via primary intraosseous (IO) injection with the QuickSleeper device vs inferior alveolar nerve block (IANB) for mandibular first molars diagnosed with symptomatic irreversible pulpitis (SIP). Sixty-four patients with a first mandibular molar with SIP were randomly divided into 2 groups: IO (n = 32) and IANB (n = 32). Each received either an IO injection with the 5th generation QuickSleeper device or a conventional IANB with 1.7 mL 4% articaine with 1:100,000 epinephrine. Success was defined as no/mild pain upon the access cavity preparation and initial filing. Injection pain, anesthetic onset, heart rate (HR) change, HR recovery time, and duration of anesthesia were also recorded and analyzed. The success rates were 40.6% for IANB and 81.2% for IO (P < .001). IO exhibited a significantly lower injection pain (P = .027), a shorter onset of action (P < .001), a greater heart rate increase (P < .001), a faster heart rate recovery time (P < .001), and a shorter duration of action (P < .001) vs IANB. Primary IO anesthesia using the fifth generation of the QuickSleeper device was more successful than IANB when using 4% articaine with 1:100,000 epinephrine to anesthetize mandibular first molars with SIP. The QuickSleeper device appeared to be a viable alternative to IANB for mandibular anesthesia.

A randomized controlled trial to assess parental satisfaction with computerized intraosseous anesthesia versus inferior alveolar nerve block in children

This study aimed to compare parental satisfaction between two pediatric dental anesthesia techniques, computerized intraosseous anesthesia (CIA) and inferior alveolar nerve block (IANB). This study was designed as a split-mouth randomized controlled clinical trial. A total of 52 parents of children undergoing dental treatment were enrolled in the study. Each participant received both CIA and IANB anesthesia, with the order of administration randomized. Parental satisfaction was evaluated using the parental satisfaction of dental local anesthetic techniques scale (PSLAS). Statistical analysis revealed that parental satisfaction regarding CIA was higher than that for IANB with a significant difference (P ˂ 0.05). However, there was no difference regarding the age, gender or the education level of the parents. (P > 0.05). This study provides insights into parental satisfaction with pediatric dental anesthesia techniques and highlights the influence of socioeconomic factors on anesthesia decision-making. Within the limitations of this trial, it was concluded that CIA was significantly superior to IANB in overall parental satisfaction. However, parental satisfaction values were lower in CIA group regarding costs and concern from complications. In addition, it was concluded that there was no difference in satisfaction levels regarding the gender, age and education level of the parents.

Influence of computerized intraosseous anesthesia compared with traditional mandibular nerve block on children's behavior: A randomized clinical trial.

Effective pain management is crucial for the successful completion of dental procedures in children. Research has examined whether computerized intraosseous anesthesia (CIOA) could serve as a safe and viable substitute for the conventional inferior alveolar nerve block (IANB) technique in pediatric patients. This study investigates the efficacy of CIOA, aiming to determine its effectiveness as an alternative anesthesia method. This study compared the efficacy of local intraosseous anesthesia using a computerized device (QuickSleeper 5) to conventional IANB anesthesia on cooperation and pain perception in children, using a randomized controlled trial design. The study included 88 healthy children, aged between 6 and 9 years, who required pulpotomy for their mandibular second primary molars. The study was approved by the local research ethics committee and registered at clinicaltrials.gov (NCT05193487). The heart rate and Venham behavior rating scale were recorded and analyzed. Categorical data were analyzed using Fisher's exact test. Age and heart rate were compared using an independent t-test for intergroup comparison. The intragroup comparison was carried out using repeated measures ANOVA, followed by the Bonferroni post hoc test. The Mann-Whitney U-test was used to analyze the Venham scale scores. The significance level was set at p < .05 RESULTS: The mean Venham score was slightly higher in the IANB group than in the CIOA group, but was not statistically significant (p = .852). One minute after anesthesia administration, the heart rate (beats per minute [BPM]) was significantly higher in the IANB group (92.30 ± 13.45) than in the CIOA group (83.20 ± 10.40) (p < .001). Additionally, there was a significant difference in heart rate values measured at different intervals within the IANB group. The QuickSleeper 5 device was found to be a feasible alternative for IANB in children over 6 years old.

Novel dental anesthetic and associated devices: a scoping review.

The efficient management of pain and discomfort is essential for successful dental treatment and patient compliance. Dental professionals are commonly evaluated for their ability to perform treatment with minimal patient discomfort. Despite advancements in traditional local dental anesthesia techniques, the pain and discomfort associated with injections remain a concern. This scoping review aims to provide a comprehensive overview of the literature on novel dental anesthetics and associated devices designed to alleviate pain and discomfort during dental procedures. The Joanna Briggs Institute and the Preferred Reporting Items for Systematic reviews and Meta-Analyses Extension for Scoping Reviews guidelines were used to prepare the review. Six databases and two sources of gray literature were searched. This review analyzed 107 sources from 1994 to 2023. Local anesthesia devices were grouped into computer-controlled local anesthetic delivery (CCLAD) systems, intraosseous anesthesia (IOA), vibratory stimulation devices, and electronic dental anesthesia (EDA). CCLAD systems, particularly the Wand and Single-Tooth Anesthesia, have been the most researched, with mixed results regarding their effectiveness in reducing pain during needle insertion compared to traditional syringes. However, CCLAD systems often demonstrated efficacy in reducing pain during anesthetic deposition, especially during palatal injections. Limited studies on IOA devices have reported effective pain alleviation. Vibrating devices have shown inconsistent results in terms of pain reduction, with some studies suggesting their primary benefit is during needle insertion rather than during the administration phase. EDA devices are effective in reducing discomfort but have found limited applicability. These findings suggest that the CCLAD systems reduce injection pain and discomfort. However, the evidence for other devices is limited and inconsistent. The development and research of innovative technologies for reducing dental pain and anxiety provides opportunities for interdisciplinary collaboration and improved patient care in dental practice.

Retrospective comparison of articaine buccal infiltration and lidocaine intraosseous anesthesia in carious mandibular molars.

It is vital to identify more efficient anesthesia techniques for the restorative or endodontic treatment of mandibular molars. Both articaine buccal infiltration anesthesia (ABI) and lidocaine inferior alveolar nerve block anesthesia (LIANB) may not provide profound anesthesia, necessitating supplementary anesthesia. This study aimed to investigate whether lidocaine intraosseous lidocaine intraosseous anesthesia (LIO) is more suitable than ABI as primary anesthesia for caries treatment of mandibular molars. This study retrospectively analyzed patients treated for advanced caries according to the International Caries Detection and Assessment System (ICDAS) 5 and 6. The study involved 48 patients, split evenly between those receiving ABI and LIO, and examined the anesthesia success rate, pain during anesthesia, onset time, duration, and post-anesthesia lower lip numbness using Chi-square and Independent T-tests. In the ABI group, 17 patients (70.8%) did not require additional anesthesia, whereas all 24 patients (100%) in the LIO group did not require additional anesthesia (P < 0.001). ABI was associated with significantly higher pain during anesthesia, slower onset time, and longer duration of anesthesia than LIO. There was no significant difference in post-anesthesia lower lip numbness between the two methods. Intraosseous anesthesia using lidocaine is more effective for treating severe caries in the mandibular molars because of its higher success rate, decreased pain during anesthesia, faster onset, and shorter recovery time.

PAIN ASSOCIATED WITH INTRAOSSEOUS ANESTHESIA WITH QUICKSLEEPER AND POST-OPERATIVE CONDITION OF THE PERFORATION SITE

Purpose: The aim of the study is to determine the pain during intraosseous anesthesia (IA) with the Quicksleeper and the post-operative state of the perforation site. Materials and methods: The subjects of the study were 58 patients who underwent successful intraosseous analgesia, indicated with treatment of caries or irreversible pulpitis of mandibular first and second molars. The Visual Analogue Scale was used to assess the pain during the perforation of the compact bone and during the infiltration of anesthetic solution into the cancellous bone. All 58 patients were followed up at the 24th hour and on the 7th day after the manipulation, and the following parameters were evaluated: condition of the perforation site and presence of palpation pain. Results: Only 10 patients registered mild pain during perforation of compact bone and 8 – during anaesthetic infiltration. At 24 hours after IA, 12 patients registered mild pain, 6 patients registered moderate pain at the perforation site. On the 7th day, we established mild pain in 4 patients. After IA a reactive inflammatory process was registered in 27% of the cases at 24 hours, while on the 7th day, the inflammatory reaction was registered in only 6% of the cases. Conclusion: The intraosseous system Quicksleeper allows painless perforation of the compact bone and infiltration of the anesthetic solution into the cancellous bone due without risk of serious post-operative complications at the site of anesthesia.

Comparative Analysis of Local Anesthetic Techniques for Pain Management in Pediatric Dental Procedures: A Randomized Clinical Trial.

The present study aims to conduct a comparative analysis of different local anesthetic techniques for pain management in pediatric dental procedures. Goal is to evaluate and compare the efficacy and safety of various local anesthetic methods to identify the most effective approach in reducing pain and discomfort during dental treatments in children. A prospective, randomized clinical trial was conducted with 60 pediatric patients (aged 3 to 10 years) undergoing dental procedures in a single dental clinic. The participants were randomly assigned into three groups: Group A received conventional infiltration anesthesia (lidocaine 2% with epinephrine 1:100,000), Group B received topical anesthesia followed by the same infiltration anesthesia, and Group C received intraosseous anesthesia using articaine 4% with epinephrine 1:100,000. The patients' demographic data, treatment details, and pre-procedure anxiety levels were recorded. The study demonstrated that all three local anesthetic techniques effectively managed pain during pediatric dental procedures. However, Group C, which received intraosseous anesthesia, showed significantly lower pain scores (mean ± standard deviation) compared to Group A and Group B: 1.5 ± 0.6, 2.3 ± 0.8, and 2.1 ± 0.7, respectively (P < 0.05). Additionally, Group C exhibited a shorter onset of anesthesia compared to Group A and Group B, with mean onset times of 1.8 ± 0.4, 3.2 ± 0.6, and 2.9 ± 0.5 minutes, respectively (P < 0.001). No significant differences in adverse events or post-procedure complications among the groups. Intraosseous anesthesia (articaine 4% with epinephrine 1:100,000) was found most effective local anesthetic technique for pain management during pediatric dental procedures.

Intraosseous anesthesia in clinical dentistry

The article shows a comparative analysis which is done in order to evaluate the effectiveness of various types of local anesthesia in the treatment of maxillary posterior teeth. The technique of intraosseous anesthesia was considered in the article and the tasks that are necessary to obtain an effective anesthetic effect were identified. The list of advantages and disadvantages of this anesthesia type was mentioned. It has been established that intraosseous anesthesia is less invasive technique due to the fact that it allows to relieve the pain locally in the area of surgical treatment, without affecting the adjacent tissues, in the area of which manipulations are not carried out.

Evaluation of the efficiency of intraosseous aesthesia in clinical dentistry

The article analyzes the effectiveness of intrabone anesthesia in the treatment of the lateral group of teeth on the upper jaw. It was established that 1 minute after the intraosseous anesthesia, all patients completely lacked pain sensitivity of the mucous membrane from the vestibular and palatine sides of the alveolar process. A similar pattern was observed 5, 10 and 30 minutes after the injection of the anesthetic. 60 minutes after the introduction of the anesthetic, a narrowing of the pain relief zones was noted. After the end of the anesthetic effect, compensatory reactions aimed at restoring the level of gingival oxygenation persisted. It was also revealed that during the study, all indicators corresponded to the norm of the ongoing process, indicating that the use of intraosseous anesthesia avoids local complications. It was concluded, that intraosseous anesthesia with modern injectors is highly effective and does not affect tissue trophism in the area of anesthesia, which allows the use of this technique for use in clinical practice.

Current Applications of Dynamic Navigation System in Endodontics: A Scoping Review.

This scoping review (SCR) was conducted to map the existing literature on dynamic navigation system (DNS), to examine the extent, range, and nature of research activity. Additionally, this SCR disseminates research findings, determines the value of conducting a full systematic review with meta-analysis, and identifies gaps in the existing literature and future directions. This SCR followed Arksey and O'Malley's five stages framework. The electronic search was performed in PubMed (Medline), Scopus (Elsevier), and Web of Science (Clarivate Analytics) databases using a search strategy. Five themes emerged during the descriptive analysis that captured the DNS application in endodontics. The DNS has been explored for creating access cavities (8/18, 44.44%), locating calcified canals (4/18, 22.2%), microsurgery (3/18, 16.6%), post removal (2/18, 11.1%), and intraosseous anesthesia (1/18, 5.5%). Out of the 18 studies included, 12 are in vitro (66.6%), five are in vivo (case report) (27.7%), and one is ex vivo (5.5%). The DNS demonstrated accuracy and efficiency in performing minimally invasive access cavities, locating calcified canals, and performing endodontic microsurgery, and it helped target the site for intraosseous anesthesia.

Programmed-release intraosseus anesthesia as an alternative to lower alveolar nerve block in lower third molar extraction: a randomized clinical trial.

BackgroundIntraosseous 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.MethodsThirty-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).ResultsThe 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.ConclusionThe results identified intraosseous anesthesia as a valid alternative to conventional anesthesia in impacted lower third molar extraction.

Clinical Observation of Intraosseous Anesthesia in Percutaneous Kyphoplasty.

Objective Percutaneous kyphoplasty (PKP) is an effective minimally invasive technique in spine surgery in recent years. General anesthesia and local anesthesia are the main ways of anesthesia in PKP, and epidural anesthesia is also applied to PKP to some extent. However, all these three anesthetic methods have their respective advantages and disadvantages. It is essential to compare and evaluate the effects of different anesthesia methods on PKP for treating spinal fractures. Method A total of 45 patients (53 vertebral bodies were included) were divided into two groups. Group A included 24 patients (29 vertebral bodies) with an average of 71 years old and Group B included 21 patients (24 vertebral bodies) with an average of 74 years old. Visual analogue scale (VAS) scores were recorded preoperatively; balloon expansion and bone cement injection were conducted intraoperatively. Then, they were recorded immediately after operation, 6 h postoperatively, to assess the pain level of the patient. Moreover, hospitalization time (days), operation duration (minutes), and bone cement injection amount (mL) had also been recorded. Results There was no significant difference in preoperative general information and VAS score. However, the VAS scores were statistically significant at both the moment of balloon expansion and injection of bone cement. At the moment of immediate postoperation, the VAS scores showed no statistically significant difference, while it showed a statistically significant difference 6 h postoperatively. Conclusion The anesthesia method by injection of 1% lidocaine hydrochloride (5 ml) into vertebral body can effectively relieve patients' pain in intraoperation and postoperation.

Periodontal complications with intrabony anesthesia

During intraosseous anesthesia (IOA), the cancellous bone is infiltrated directly with the anesthetic through the cortical bone. Advantages of IOA are seen in the immediate onset of action without co-anesthetics of the surrounding soft tissue and in the low dosage. The industry-supported statement that no necroses of the periodontal structures are to be feared and that there is no risk of fracture of the injection needle is refuted by clinical progress reports form the practice. These risks are rarely mentioned in current studies; on the contrary - IOA continues to be presented as particularly low in complications. In contrast, more attention should be paid to whether necrotic bone changes can be displayed over time, which may be related to the anesthesia technique. It would be desirable to systematically conduct clinical studies in the future with the aim of recording possible long-term damage by the IOA. In the present study, this type of anesthesia is evaluated with regard to its clinical application and periodontal risks, and possible examples of the course of complication are radiographically presented and discussed based on the rather scarce literature.

SAFETY OF INTRAOSSEOUS ANESTHESIA IN DENTISTRY.

The aim is to increase safety and efficiency of intraosseous anesthesia by automated injectors. Duration of intraosseous anesthesia depends on the concentration of epinephrine in the local anesthetic. Intraosseous analgesia has a high patient satisfaction rate in terms of efficiency and comfort – more than 97%.

A percepção dolorosa (n=3) e a eficácia (n=4) foram os fatores mais avaliados nos trabalhos. A anestesia transcortical é uma alternativa às técnicas convencionais e pode ser aplicada em casos de falhas ou insuficiências da anestesia convencional em exodontias simples e complexas.

Intraosseous Anesthesia Using Dynamic Navigation Technology

IntroductionThis study presents a novel method to deliver intraosseous anesthesia using dynamic navigation technology. The study aimed to evaluate its safety and 3-dimensional (3D) accuracy in comparison to traditional freehand injection of intraosseous anesthesia. MethodsSix identical sets of 3D-printed surgical jaw models (TrueJaw; DELendo, Santa Barbara, CA) comprising simulated alveolar and dental anatomy with 54 interradicular sites were used in this study. The injection sites were equally distributed based on the range of the inter-radicular distance (ie, 1.5–2.5 mm, 2.5–3.5 mm, and 3.5–4.5 mm). A board-certified endodontist randomly completed intraosseous drilling at inter-radicular sites of varying distance using freehand technique and the Navident dynamic navigation system (ClaroNav, Toronto, Ontario, Canada) with the X-Tip system (Dentsply Sirona, York, PA). The rate of root perforation associated with inter-radicular distance was compared between the 2 groups using the Fisher exact test. Two-dimensional (2D) and 3D horizontal, vertical, and angulation discrepancies between the planned and dynamically navigated guide sleeves were digitally measured using superimposed cone-beam computed tomographic scans. Analysis of variance models were used to determine if the interdental distance was associated with the accuracy measures from the dynamic navigation system. The significance level was set at 0.05. ResultsThe rate of root perforation was significantly higher for the freehand group than the dynamic navigation (22% vs 0%, P < .05). For dynamic navigation, the 2D entry deviation was 0.71 mm (95% confidence interval [CI], 0.56–0.87). The mean 2D horizontal deviation was 0.96 mm (95% CI, 0.79–1.14), and the mean 2D vertical deviation was 0.70 mm (95% CI, 0.55–0.84). The 3D deviation at the tip was on an average 1.23 mm (95% CI, 1.05–1.42). The overall 3D angular deviation was on average 1.36° (95% CI, 1.15–1.56). The inter-radicular distance was not significantly associated with any 2D or 3D discrepancies. ConclusionsSuccessful and accurate drilling of dynamically navigated intraosseous delivery occurred in 100% of injection sites irrespective of the inter-radicular distance. It was significantly safer in comparison to freehand intraosseous drilling to prevent injury of the roots of the adjacent teeth in close proximity.

Intraosseous anesthesia in symptomatic irreversible pulpitis: Impact of bone thickness on perception and duration of pain.

BackgroundIntraosseous anesthesia (IO) allows the anesthetic solution to be injected directly into the cancellous bone. The anesthetic solution immediately reaches the periapical region, and thus the axonal area of the nerve, where it can temporarily disable the sodium pump. The effect is felt almost without any time delay, and only a small amount of anesthetic solution is required.MethodsThis study aims to investigate the efficacy of IO using the Anesto® device after infiltration anesthesia (IA) and/or inferior alveolar nerve block anesthesia (IANB) failed to work in symptomatic irreversible pulpitis (hot tooth). The 33 patients included in the study were treated additionally with 1.7 ml articaine hydrochloride with 1:100,000 epinephrine hydrochloride (Ultracain® D-S, Sanofi-Aventis, Frankfurt, Germany) IO.ResultsThe electrical pulp test showed that 95.76% of the volunteers reacted positively to the combination of IANB or IA with the IO. In women, the additive IO was effective at 97.22%. In men, the IO led to pain elimination in 94.00% of cases. The duration of the IO was less than a quarter of an hour (13.03 min). The IO worked longer in women than in men (13.61 min vs. 12.33 min). Overall, more than every third tooth that needed trepanation was located in the posterior area of the mandible (36.4%). Treatment of hot teeth in this area was associated with an increased pulse rate and increased residual pain. There was a moderate correlation (Spearman-Rho [IRI] = 0.280) between the Visual Analog Scale (VAS) score and bone density, and a significant correlation (IRI = 0.612) between subjective residual pain and bone width. The IO resulted in a moderate, transient increase in the pulse rate by approximately 20 bpm. This is similar to the temporary increase in heart rate after conventional anesthesia techniques in non-preloaded patients and can be considered clinically irrelevant.ConclusionIO with the Anesto® device as an extension and deepening of local pain elimination is recommended for the treatment of hot teeth.

The Clinical Comparison of Intraosseous and Intravenous Anesthesia (Thiopental-Na) in Pigeon

Background: Intraosseous injection is a way to administration of drugs. Objective: The clinical comparison of intraosseous and intravenous injection of Thiopental-Na. Methods: First all birds (Twenty six healthy pigeons) were split out into two groups randomly. Group A received 20 mg kg-1 Thiopental-Na by intraosseous route and group B intravenous route. After one week that needs for washing out of drug, group A received 20 mg kg-1 Thiopental-Na by intravenous route and group B intraosseous route. The respiratory rate (fR), heart rate (HR) and cloacal temperature (T) were measured before (0 minute) and 1, 5, 10, 20 and 30 minutes after anesthetic drug administration. Reaction to injection, number of efforts for injection, duration to onset the anesthesia and different scores of anesthesia were checked. Returning from anesthesia in two groups was written out and compared. Results: Statistical assessment showed anesthesia onset in the method of intravenous injection was significantly less than the method of intraosseous injection (p=0.003), and the fR in two groups was different in 1 minute after drug administration (P=0.036). There was not statistically difference in other minutes for fR, HR and T in two groups (P >0.05). Statistical analysis showed that there were no significant differences in terms of number of efforts for anaesthetizing as well as anesthesia stage in both methods in different minutes (p>0.05). Also no significant alterations were recorded for recovery time for both groups. There was not any visible lameness or pain for intraosseous route after recovery. Conclusions: Intraosseous anesthesia injection in birds is a practicable and fast procedure and comparable with intravenous route.

Medical solution to needle breakage during local anesthesia

Needle breakage may be a damaging experience for both medical practitioners and patients. Medical literature provides numerous cases of dental practitioners being confronted with this problem. We have studied the clinical case of the patient L. at the Moscow State University of Medicine and Dentistry involving needle breakage during conductive anesthesia. We propose our medical approach to solving this issue alongside with a desirable course of action, providing additional recommendations and suggesting intraosseous anesthesia as a safer type of pain management.
