“…As mentioned previously, supplemental anesthesia can also be provided via other routes. Both intraligamentary and intraosseous techniques deliver the anesthetic to the cancellous bone surrounding the apices of injected teeth (6, 79). While the intraligamentary injection can be provided with no additional armamentaria, there are limitations to the volume of anesthetic deposited, and a significant incidence of postoperative pain may ensue (80).…”

“…Intraligamentary anaesthesia is not a single tooth anaesthetic (Kim 1986). Smith & Walton (1983) have shown that in dogs, solutions injected into the periodontal ligament of one tooth reach the periapical region and pulps of adjacent teeth. D'Souza et al .…”

“…Thus the injection represents a potential cause of endocarditis in ‘at‐risk’ groups. There is rapid entry of local anaesthetic and vasoconstrictor into circulation . Although direct entry of the needle into the lumen of a blood vessel is unlikely; using the periodontal ligament technique, the solution does reach the vasculature via the socket walls (Smith & Walton 1983, Dreyer et al . 1983, Garfunkel et al .…”

Supplementary routes to local anaesthesia

The satisfactory provision of many dental treatments, particularly endodontics, relies on achieving excellent pain control. Unfortunately, the administration of a local anaesthetic solution does not always produce satisfactory anaesthesia of the dental pulp. This may be distressing for both patient and operator. Fortunately, failure of local anaesthetic injections can be overcome. This is often achieved by using alternative routes of approach for subsequent injections. Nerves such as the inferior alveolar nerve can be anaesthetized by a variety of block methods. However, techniques of anaesthesia other than the standard infiltration and regional block injections may be employed successfully when these former methods have failed to produce adequate pain control. This paper describes some supplementary local anaesthetic techniques that may be used to achieve pulpal anaesthesia for endodontic procedures when conventional approaches have failed. Although some of these techniques can be used as the primary form of anaesthesia, these are normally employed as 'back-up'. The methods described are intraligamentary (periodontal ligament) injections, intraosseous anaesthesia and the intrapulpal approach. The factors that influence the success of these methods and the advantages and disadvantages of each technique are discussed. The advent of new instrumentation, which permits the slow delivery of local anaesthetic solution has led to the development of novel methods of anaesthesia in dentistry. These new approaches are discussed.

To test the hypotheses, studies have been conducted on the spread of injected solution, using radiopaque materials [lo-131, dyes [9] and India ink [13,14]. The findings suggested that the solution usually spreads through the medullary spaces rather than along the periodontal ligament.…”

Summary. The spread of local anaesthetic solution administered with a pressure syringe has not been studied as extensively in young animals having primary or mixed dentitions as in adult animals. The purpose of this investigation was to study the distribution of local anaesthetic solution injected into the periodontal ligament of young dogs. India ink was added to carpules containing 2% lidocaine and 1:100,000 epinephrine, and the spread of solution was examined macroscopically and microscopically. Injections were made with a pressure syringe (Ligmaject) at 58 sites mesial and distal to primary teeth in five dogs aged 3–9 months. Three dogs were killed within 12 hours, the other two after 5 days. Spread of the ink was studied in non‐decalcified slabs, in three‐dimensional cleared specimens, and in histological sections. The solution usually reached the alveolar bone crest, seeped under the periosteum and alongside vascular channels into bone marrow, reaching natural cavities such as the crypts of tooth buds and the mandibular canal. The ink did not penetrate into the enamel organ or contact the permanent tooth buds. The solution appeared to spread along the path of least resistance, governed by the intricacies of anatomical structures and fascial planes. Therefore the risk of mechanical damage to permanent tooth germs appears to be minimal. Résumé. La diffusion de solutions d' anesthésiques locaux, injectées à l'aide d'une seringue sous pression dans les dentitions primaires ou mixtes de jeunes animaux n' a pas été étudiée de façon extensive comme celà a été fait chez les animaux adultes. Le propos de cette recherche est l'étude de la distribution des solutions d' anesthésiques locaux injectées dans le ligament parodontal de jeunes chiens. De l'encre de Chine a été ajoutée aux carpules contenant de la lidocaïne à 2% et de l'épinéphrine à 1/100,000 et la diffusion de la solution a été etudée macroscopiquement et microscopiquement. Les injections ont été faites par seringue sous pression (Ligmaject) dans 58 sites mésiaux distaux de dents temporaires de cinq chiens âgés de trois à neuf mois. Trois chiens ont été sacrifiés au bout de 12 heures, les deux autres aprés 5 jours. La diffusion de l'encre a été étudée dans des coupes non‐déminéralisées, dans des specimens à trois dimensions et dans des coupes histologiques. La solution atteignait habituellement la crête osseuse alvéolairs, s'infiltrait sous le périoste et le long des trajets vasculaires dans la moelle osseuse, atteignant les cavités naturelles comme le sac des follicules dentaires et la canal mandibulaire. l'encre ne pénétrait pas dans l'émail et n'était pas en contact avec les follicules des dents permenentes. La solution diffusait le long des trajets de moindre résistance, dans les dédales des structures anatomiques et des plans faciaux. Ainsi le risque de traumatisme mécanique des germes des dents permanentes apparait comme minime. Zusammenfassung. Bei einem Versuch mit einem Jungtier mit erster oder gemischten Dentition wurde die Diffusion eines Lokala...
