intraosseous dental anesthesia

BACKGROUND: Because of controversial results from clinical studies comparing different dental local anesthesia methods in children, the primary objective of this randomized, split-mouth, crossover, controlled trial was to compare pain intensity during local anaesthesia (LA) performed with a computer-controlled LA delivery system (C-CLADS) versus a conventional syringe (CONV). Secondary objectives included comparisons during dental treatment. METHODS: Participants (4-8 years) with tooth pair requiring similar treatment were recruited from five French hospitals...

OBJECTIVE: 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. METHODS: 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 development of dynamic navigation system (DNS) has facilitated the development of modern digital medicine. In the field of dentistry, the cutting-edge technology is garnering widespread recognition. Based on the principles of 3-dimensional visualization, virtual design, and precise motion tracking, DNS is mainly composed of a computer, a tracking system, specialized tracer instruments, and navigation software. DNS employs a workflow that begins with preoperative data acquisition and imaging data reconstruction, followed by surgical instrument calibration and spatial registration, culminating in real-time guided operations...

BACKGROUND: Surgical extraction of impacted mandibular third molars is the most common procedure performed by oral surgeons. The procedure cannot be performed effectively without achieving profound anesthesia. During this procedure, patients may feel pain during surgical bone removal (at the cancellous level) or during splitting and luxation of the tooth, despite administration of routine nerve blocks. Administration of intraosseous (IO) lignocaine injections during third molar surgeries to provide effective anesthesia for pain alleviation has been documented...

BACKGROUND: Pain control is one of the most important aspects that can affect parental satisfaction of the dental care provided for children. Dental local anesthesia has the highest impact on pain sensation of the children. However, there is no scale in the literature to assess parental satisfaction of dental local anesthetic techniques. OBJECTIVES: This study was aimed to assess the parental satisfaction with dental local anesthetic techniques for their children through designing a scale that reflects satisfaction and to study the validity and reliability of this scale...

Computer-controlled local anesthetic delivery systems (CDS) represent one of the resources that have progressed the most in recent years, but their efficacy and applicability in pediatric dentistry is still the subject of certain controversies. This randomized, controlled, split-mouth clinical trial assessed two CDS in children ( n = 100) with deep caries in the temporary dentition that required invasive therapeutic procedures, using inferior alveolar nerve block as the gold standard. Half of the patients ( n = 50) underwent the intraligamentary technique (Wand STA® ) on one side of the mouth and conventional inferior alveolar nerve block on the contralateral side, while the other half ( n = 50) underwent the intraosseous technique (QuickSleeper® ) on one side of the mouth and conventional inferior alveolar nerve block on the contralateral side...

BACKGROUND: In dentistry, needles are the most feared and anxiety-causing tool, making anesthetic injection a worrying practice for patients. AIM: To evaluate the effect of intraosseous anesthesia (IOA) and needle-free dental anesthesia (NFA) on pain levels in systemically healthy 8-10-year-old patients. PATIENTS AND METHODS: Twenty patients aged 8-10 years were included in this cross-over study. Specifically, the pain was measured by Wong Baker, pulse rate (PR), and salivary opiorphin levels (SOL)...

Intraosseous xanthoma of the mandible is a rare benign disorder. A 17-year-old male patient presented with a suspected abscess in the right mandibular third molar, detected on a panoramic radiograph. The patient had no history of systemic or lipid-related metabolic diseases and complained of no specific symptoms or pain. A radiographic examination revealed a heterogeneous radiolucency extending from the apical to the distal aspect of the right mandibular third molar tooth germ. The lesion measured 9×16×24 mm (antero-posterior×mediolateral×supero-inferior) and showed a relatively well-defined, multilocular, foamy appearance with hyperostotic borders spreading to the inferior alveolar nerve canal...

Background: Intraosseous 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...

In the scientific literature, one can find conflicting assumptions about the presence of «proper mental bone» and «upper and lower lingual canals», which make up a separate ossified area in the chin of the mandible and the system of blood supply and innervation. However, calling these lesions «lingual canals» or «incisal canals», as is often found in various articles, is incorrect based on the position of International Anatomical Terminology. This is due to the lack of topographic reference in the term, which can equally be understood as the canal of the tongue, the neurovascular bundle of the same name, and the root canal system of the teeth of the lower jaw and can also be associated with the maxilla...

Background and Objectives : Guided bone regeneration (GBR) surgeries are used for dental implant placements with insufficient bone volume. Biomaterials used in GBR are expected to produce sufficient volume and quality of bone swiftly. This study aims to histologically evaluate the effectiveness of the use of Hyalonect membranes alone or with autogenous grafts in intraosseous defects. Materials and Methods : This study is an experimental study on sheep. Surgeries were performed under general anesthesia in accordance with ethical rules...

Background: Intraosseous 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. Methods: This 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)...

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...

INTRODUCTION: This 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. METHODS: Six identical sets of 3D-printed surgical jaw models (TrueJaw, DELendo, Santa Barbara, CA) comprising of simulated alveolar and dental anatomy with fifty-four inter-radicular sites were used in this study...

The aim of research - to assess the feasibility and effectiveness, of the intraosseous method of anesthesia, with the Quick Sleeper injection system on the toothless area of ​​the alveolar bone during dental implantation. Clinical and physiological studies were conducted to study the features of performing intraosseous anesthesia on the site of alveolar bone adentia in the absence of the usual anatomical topographic landmarks. New computer technologies, as well as modern methods of patient examination and observation were used...

BACKGROUND: The classical anatomical representation of the lingual relief of the mental region of the mandible reflects the presence of geniohyoid as well as genioglossus attachment areas, which are divided into two or single areas. The International Anatomical Terminology (contains references to the presence of upper and lower spinae mentales, but the terminology does not reflect the content of these structures. The aim of this study was to examine and classify the lingual canals of the mental region...

Intraosseous venous malformation of the mandible is rare. A 59-year-old woman was referred to our hospital for evaluation of a radiolucent lesion in the left body of the mandible that had been detected on a routine radiologic dental checkup. The patient wished for follow-up rather than operation. After 2 years' follow-up, the radiolucent lesion had slowly grown, and the patient decided to have an operation. The lesion was removed surgically using the piezosurgery system, and conservation of the inferior alveolar nerve was achieved under general anesthesia...

OBJECTIVES: This study aimed at analyzing the effect of the temporary removal of trigeminal dental afferents on electrogustometric thresholds (EGMt). MATERIAL AND METHODS: EGMt were measured in 300 healthy subjects randomized in three groups, in nine loci on the right and left side (RS, LS) of the tongue surface before and after anesthesia. Group IAN (n = 56 RS, n = 44 LS) received intraosseous local anesthesia of the inferior alveolar nerve (IAN). Group MdN received mandibular nerve (MdN) block targeting IAN before its entrance into the mandibular foramen (n = 60, RS, and n = 40, LS); group MxN receiving maxillary nerve (MxN) anesthesia (n = 56 RS and n = 44 LS) was the control group...

Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here, we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window...

The traditional classification methods of dental local anesthesia must be modified. In this paper we proved that the vascular mechanism is leading component of spongy injection. It is necessary to take into account the high effectiveness and relative safety of spongy anesthesia, as well as versatility, ease of implementation and the growing prevalence in the world. The essence of the proposed modification is to distinguish the methods in diffusive (including surface anesthesia, infiltration and conductive anesthesia) and vascular-diffusive (including intraosseous, intraligamentary, intraseptal and intrapulpal anesthesia)...
