Successful Intentional Replantation of a Severely Compromised Tooth Using 3 Types of Phototherapy: A Case Report.

Intentional replantation (IR) is an emerging and cost-effective last-resort treatment for persistent apical periodontitis. Adjunctive phototherapy for IR aims to improve the management of challenging cases by enhancing disinfection, stimulating healing and promoting regeneration. We report a novel phototherapy-assisted IR protocol conducted on a compromised lateral incisor with an extensive periapical infection (Ø > 10 mm) in a 68-year-old diabetic male.

Photobiomodulation: Implications for Anesthesia and Pain Relief.

Objective: This review examines the evidence of neural inhibition as a mechanism underlying pain relief and anesthetic effect of photobiomodulation (PBM).

Background: PBM for pain relief has also been used for more than 30 years; however, the mechanism of its effectiveness has not been well understood.

Methods: We review electrophysiological studies in humans and animal models and cell culture studies to examine neural responses to PBM.

Low-power pulsed Nd:YAG laser irradiation for pre-emptive anaesthesia: A morphological and histological study.

Background And Aims: To determine if tooth structure or dental pulp of normal healthy human premolar teeth to be extracted for orthodontic reasons exhibit morphological or histological changes following dental anaesthesia by pulsed Nd:YAG laser and subsequent cavity preparation (CP). Materials (Subjects) and Methods: 54 bilateral paired of human, healthy premolar teeth identified for inclusion in a clinical trial of Nd:YAG-induced anaesthesia and subsequently extracted for orthodontic reasons, were randomly divided into 4 treatment groups: Group 1 - teeth (n=44) were irradiated with 150 µs pulsed Nd:YAG laser-1064 nm (American Dental Laser, dLase300, Sunrise Technologies Inc., Folsom, CA, USA; Average power: 1.

Chronic inflammatory demyelinating polyradiculoneuropathy: from pathology to phenotype.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an inflammatory neuropathy, classically characterised by a slowly progressive onset and symmetrical, sensorimotor involvement. However, there are many phenotypic variants, suggesting that CIDP may not be a discrete disease entity but rather a spectrum of related conditions. While the abiding theory of CIDP pathogenesis is that cell-mediated and humoral mechanisms act together in an aberrant immune response to cause damage to peripheral nerves, the relative contributions of T cell and autoantibody responses remain largely undefined.

Clinical implications of Schwann cell biology.

The neuroglia of the peripheral nervous system (PNS) are derived from the neural crest and are a diverse family of cells. They consist of myelinating Schwann cells, non-myelinating Schwann cells, satellite cells, and perisynaptic Schwann cells. Due to their prominent role in the formation of myelin, myelinating Schwann cells are the best recognised of these cells.
