Nowadays, the bactericidal effect of laser irradiation is well known in endodontic therapy. Many studies showed that, in combination with an appropriate shaping and cleaning of root canal system, laser irradiation, inside the root canal, could increase the percentage of bactericidal effect in endodontic treatment. Three clinical cases of teeth with periapical chronic periodontitis are presented...

We demonstrate a laser-assisted dry transfer technique for assembling patterns of vertically aligned carbon nanotube arrays on a flexible polymeric substrate. A laser beam is applied to the interface of a nanotube array and a polycarbonate sheet in contact with one another. The absorbed laser heat promotes nanotube adhesion to the polymer in the irradiated regions and enables selective pattern ...

Vocal fold scarring can arise from disease or postsurgical wound healing and is one of the predominant causes of voice disorders. Focused ultrafast laser pulses have been previously demonstrated to create tightly confined sub-surface ablation in a variety of tissue, including vocal folds. Here, we demonstrate how we can take advantage of this unique ability of ultrafast laser ablation to create...

Today's gold standard in the treatment of infrasaccal primary acquired nasolacrimal duct obstruction (PANDO) is external dacryocystorhinostomy (DCR), a relatively invasive procedure that can be performed after failure of recanalizing treatments. However, with progress in the field of diode laser technology, new approaches have emerged. Laser-assisted transcanalicular DCR with subsequent bicanal...

introduction: corticotomy-facilitated orthodontics provides a means for rapidly moving teeth purportedly with little damaging effects to the periodontium and with greatly reduced treatment time. the aim of this study was to enhance the orthodontic tooth movement by reducing the cortical bone layer (resistant to bone re-sorption relative to spongious bone) following erbium, chromium doped yttriu...

Background Melasma is a difficult-to-treat hyperpigmentary disorder. Ablative fractional laser (AFL)-assisted delivery of topically applied drugs to varied targets in the skin has been an area of ongoing study and research. Objective The objective of this study was to evaluate the efficacy and safety of fractional erbium-doped yttrium aluminum garnet (Er:YAG) laser as an assisted drug deliver...

PURPOSE To determine whether postoperative ocular inflammation is less after femtosecond laser-assisted cataract surgery than after conventional phacoemulsification (manual) cataract surgery. SETTING Private clinic, Launceston, Tasmania, Australia. DESIGN Prospective consecutive investigator-masked nonrandomized parallel cohort study. METHODS Consecutive cataract patients who had femtosec...

PURPOSE To compare the vitreous loss complication rate of manual phacoemulsification cataract surgery with that of femtosecond laser-assisted cataract surgery. SETTING Mercy Eye Specialists, Springfield, Missouri, USA. DESIGN Retrospective single-center case series. METHODS Cataract surgeries from 2010 to 2014 performed by 4 surgeons were audited for rates of vitreous loss. Vitreous loss ...

AIM This baseline study aims to find out the young patients' perception on different surgical management of the disto-oclusal gingival operculum in second mandibular molars: the conventional technique and the laser assisted one. MATERIAL AND METHODS The current study included a batch of 20 patients who needed surgical bilateral removal of the disto-oclusal operculum in second mandibular molar...
