Rationale for using a double-wavelength (940 nm + 2780 nm) laser in endodontics: literature overview and proof-of-concept

Abstract

Aim: The goal of endodontic research is to report interventions, techniques or protocols that are most likely to deliver the outcomes that are of most interest to both clinicians and patients. The development of a double-wavelength laser delivered concomitantly and through the same radial firing tip (RFT) may provide a unique combination of beneficial properties that may clinically surpass all previously reported laser-assisted protocols.

The aim is to present a rational literature overview that could support the adoption of simultaneous use 2780 and 940 nm wavelengths for smear layer removal and disinfection respectively.

Systematic Literature Review: Influence of Low-Level Laser on Orthodontic Movement and Pain Control in Humans

Abstract

Objective: The purpose of this study was to systematically review the literature to check the influence of low level laser (LLL) on orthodontic movement and pain control in humans, and what dose ranges are effective for pain control and increased speed of orthodontic movement. Methods: Computerized and manual searches were conducted up to January 4, 2014 for clinical studies that addressed these objectives. The selection criteria required that these studies (1) be prospective controlled clinical trials (CCT) and randomized clinical trials (RCT); (2) only use LLL in both infrared and visible red wavelengths, a laser with emission of constant wave; (3) have all main parameters of dose described, or at least conditions for calculation of the energy, in Joules; and (4) be published in Portuguese, English, or Spanish and be meta-analyses.

Laser-assisted Oral and Maxillofacial Surgery for Patients on Anticoagulant Therapy in Daily Practice

Purpose: In general clinical practice, the oral and maxillofacial surgeon is frequently required to treat patients on anticoagulant therapy. The purpose of this paper is to review the literature in order to provide evidence-based guidelines for the management of anticoagulated patients undergoing oral and maxillofacial surgery.

Materials and Methods: Literature published over the past 40 years was reviewed. The management of patients on anticoagulant therapy as well as laser-assisted oral and maxillofacial surgery is discussed.

Results: Currently, the continuation of anticoagulant therapy is strongly encouraged when INR is within the therapeutic range and meticulous local hemostatic measures are taken.

Conclusion: It may be concluded that the risk of postoperative bleeding is outweighed by the higher risk of thromboembolism after withdrawal of the anticoagulant therapy and thus continuation of the anticoagulant regimen is encouraged. Laser-assisted oral and maxillofacial surgery in daily practice has enabled surgeons to achieve controlled hemostasis and minimize intra- and postoperative hemorrhage without discontinuing anticoagulants.

Effects of Low-Intensity Laser Therapy on the Orthodontic Movement Velocity of Human Teeth: A Preliminary Study

Background and Objectives: Low-intensity laser therapy (LILT) has been studied in many fields of dentistry, but to our knowledge, this is the first time that its effects on orthodontic movement velocity inhumansare investigated.

Study Design/Patients and Methods: Eleven patients were recruited for this 2-month study. One half of the upper arcade was considered control group (CG) and received mechanical activation of the canine teeth every 30 days.
