INTRODUCTION: In the treatment of patients with symptomatic irreversible pulpitis, endodontic debridement is a predictable method to relieve pain. However, there are clinical situations in which emergency care cannot be provided immediately. An unexplored treatment option in these cases may be the use of a long-acting anesthetic to reduce pain in untreated irreversible pulpitis. Some medical studies have shown potential for infiltrations of liposomal bupivacaine (Exparel; Pacira Pharmaceuticals, San Diego, CA) to prolong pain relief and reduce opioid use postoperatively...

INTRODUCTION: When the mandibular permanent second molar becomes impacted, it is identified as a malocclusion that needs treatment as it often leads to unwanted complications such as caries and periodontitis of the adjacent permanent first molar. Other less common complications include root resorption of the adjacent first molar root or continued root development to be in close proximity to the inferior dental alveolar nerve. MATERIALS AND METHODS: This paper seeks to differentiate various levels of severity of impaction and review treatment options that are considered clinically available for the proper management of the impacted mandibular permanent second molar...

Our aim was to evaluate the efficacy of clonidine with lidocaine as a local anaesthetic agent for inferior alveolar mandibular nerve blocks for dental extraction. We studied 200 patients who required extraction of mandibular teeth and divided them into two groups of 100 each, the first of which was given lidocaine and adrenaline (12.5μg/ml) and the second lidocaine and clonidine (15μg/ml). Cardiovascular vascular variables (blood pressure, heart rate, and mean arterial pressure) were assessed before, during, and after extraction, and postoperative pain was measured on a visual analogue scale...

Aging is associated with peripheral nerve degradation and bone destruction. The aim of the study is to elucidate the influence of sensory denervation on bone metabolism in different age groups by establishing a modified unilateral inferior alveolar nerve transection (IANT) model. The rats, divided into young, middle-aged and aged group, were sacrificed at 1, 2, 4 and 8 weeks after right IANT. The histological changes of mandibles were analyzed by fluorescent double labeling, micro-CT, HE, TRAP and anti-CGRP immunohistochemical staining...

Temporomandibular joint (TMJ) pain can be difficult to diagnose and treat. We describe a patient with left jaw pain after right hemimandibulectomy. The patient was initially managed conservatively, which failed to reduce pain. He was then administered inferior alveolar nerve block and TMJ injection with steroid and local anesthetic. These injections provided temporary pain relief that lasted approximately 1 month and the pain recurred. Computed tomography scan showed lateral displacement of left mandibular condyle...

Introduction. The aim of this paper was to describe two cases of IAN infection-induced paresthesia and to discuss the most appropriate treatment solutions. Methods. For two patients, periapical lesions that induced IAN paresthesia were revealed. In the first case, the tooth was previously endodontically treated, whereas in the second case the lesion was due to pulp necrosis. Results. For the first patient, a progressive healing was observed only after the tooth extraction. In the second patient, the paresthesia had resolved after endodontic treatment...

BACKGROUND: Prophylactic removal of asymptomatic disease-free impacted wisdom teeth is surgical removal of wisdom teeth in the absence of symptoms and with no evidence of local disease. Impacted wisdom teeth may be associated with pathological changes, such as pericoronitis, root resorption, gum and alveolar bone disease (periodontitis), caries and the development of cysts and tumours. When surgical removal is carried out in older people, the risk of postoperative complications, pain and discomfort is increased...

Osteoid osteoma, a rare benign osteoblastic tumor first described by Jaffe in 1935, is characterized as a small but painful lesion that mostly affects younger people. Usually benign and harmless, osteomas are removed for pain or esthetic reasons.Piezoelectric surgery is also increasingly being used effectively in major and minor osseous oral and maxillofacial surgeries, in delicate areas. It is used regularly for various procedures, including sinus lift procedures, bone graft harvesting, osteogenic distraction, ridge expansion, inferior alveolar nerve decompression and lateralization, cyst removal, dental extraction, and impacted tooth removal...

OBJECTIVE: Malocclusion with deep overbite and facial esthetics improve when facial height is intentionally increased during orthodontic extrusion of the posterior teeth. Thus, a better understanding of post-treatment stability of increased occlusal vertical dimension (iOVD) in adult patients is important. We focused on the jaw-opening reflex (JOR), which plays an important role in the control of jaw movements during mastication, and investigated the effects of iOVD on the JOR in rats with an electrophysiological technique...
