Determination of Optimal Separation Times for Dual-Pulse SWEEPS Laser-Assisted Irrigation in Different Endodontic Access Cavities.

Background And Objectives: The purpose of this ex vivo study is to investigate whether it is possible to pre-determine and set the optimal separation times for the SWEEPS Er:YAG laser pulses pair during laser-assisted irrigation of endodontic root canals based on known lateral dimensions of the endodontic access cavities of different types of teeth.

Study Design/materials And Methods: As the optimal SWEEPS laser pulse pair separation for enhanced shockwave generation depends on the life-cycle of a single-pulse bubble, measurements of the oscillation time T of the Er:YAG laser-generated bubble were made in 23 different endodontic access cavities of different types of teeth progressively widened in three different steps, into larger cavities, for a total of 69 cavities of different shapes and sizes. Different fiber-tip geometries (flat and radial), laser pulse energies (10 mJ and 20 mJ) and depth of fiber-tip insertion (2 mm and 4 mm) were also investigated.

Measurement of Pressures Generated in Root Canal During Er:YAG Laser-Activated Irrigation.

To measure distribution of pressures along the depth of the root canal during erbium-doped yttrium aluminum garnet (Er:YAG) laser-activated irrigation (LAI) with different modalities and fiber tip (FT) geometries. A new LAI modality based on the delivery of synchronized pairs of Er:YAG laser pulses to generate enhanced irrigant streaming and shock wave emission was recently introduced. However, the influence of FT geometry on efficacy and comparison with single pulse modality is not yet presented.

Antibiofilm Activity of Three Different Irrigation Techniques: An in Vitro Study.

The microbial infection of the endodontic space occurs in a necrotic tooth as a result of dental caries, trauma, periodontal disease, or previous root canal therapy. The disruption of the biofilms and the reduction of the bacterial load inside root canals are crucial for the success of root canal therapy. The aim of this study was to compare, in vitro, the antibiofilm efficacy of a novel passive sonic irrigation (PSI) device with passive ultrasonic irrigation (PUI) and conventional needle irrigation (CNI).

Aim: Anomalous maxillary median labial frenum may be associated with undesired effects such as persistence of diastema between anterior teeth or traction of marginal gingiva. The aim of this study was to propose a surgical frenum repositioning technique that is minimally invasive, safe, easy, reproducible, and predictable. Another objective of the study was to identify clinical scenarios that could have indication for labial frenectomy associated with early orthodontic therapy, so as to justify early frenum repositioning in children.

Paediatric laser dentistry. Part 4: Soft tissue laser applications.

Lasers can provide effective soft tissues applications in children. All the wavelengths produce incision and vaporisation of oral tissues, together with a high bactericidal effect. The haemosthatic effect varys according to the wavelength used, and the choice of a visibile, near, medium or far infrared laser allows a better interaction with specific targets, gingiva, mucosa, frenum, or oral pathology.

Paediatric laser dentistry. Part 1: General introduction.

Knowledge of the physical characteristics of different laser lights and optical and thermal properties of oral tissues is very important to understand the interaction of dental lasers with biological tissues. Choosing the correct dental laser is crucial to match specific wavelengths with target chromophores of different tissues; this affinity makes laser irradiation selective and therefore minimally invasive. Various types of lasers are used in dentistry, offering a viable alternative to low and high-speed handpieces and surgical blades, and also minimising fear and discomfort of the patient.

Pericarditis mimicking Brugada syndrome.

Introduction: Brugada syndrome (BrS) is a genetic heart disorder due to alteration of the ion channels function that causes an impaired in the cardiac conduction system. It is characterized by an abnormal electrocardiogram pattern and may be complicated by malignant ventricular arrhythmias. Pericarditis is an inflammation of the pericardium and 90% of isolated cases of acute pericarditis are idiopathic or viral.

Low iodine intake during pregnancy: relationship to placental development and head circumference in newborn.

Introduction: Iodine is considered to be an essential micronutrient in pregnant women. Iodine placental transport to the embryo-fetus is essential for hormone synthesis and is crucial for nervous system development. However, the relationship between iodine intake and placental weight and its potential implications for the newborn have not been studied.

Lasers in dental traumatology and low level laser therapy (LLLT).

Background: Dental trauma in children is a frequent and often complex clinical event in which laser-assisted therapy, particularly using erbium lasers, can offer new treatment possibilities, improving the outcomes and reducing the associated complications.

Review: In particular, it is worth considering that the use of laser-assisted therapies is associated with a marked reduction in the use of analgesics and anti-inflammatory medications compared with conventional procedures. Laser anaesthesia is another interesting and challenging area.

Lasers in dental traumatology.

Aim: Dental traumas are frequent in children. They can be complex events and sometimes real emergencies. Since very little attention is devoted to this topic in the international literature and there are no well-coded laser guidelines for these specific clinical events, our aim is to consider and present those situations in which laser-assisted therapy can offer new treatment possibilities.
