Keratoacanthoma (KA) is a subtype of squamous cell carcinoma whose development has been linked to excessive sun exposure, immunosuppression, and trauma. Given the rapidly expanding therapeutic armamentarium for anti-aging modalities in dermatology, reports of KA secondary to invasive cosmetic procedures are on the rise. We present a case of eruptive KAs after full- eld ablative Erbium:YAG 2940 nm laser resurfacing of the face that resolved with minimal intervention. This case demonstrates the potential for a rare yet signi cant laser complication that may warrant discussion during the consenting process...

Medication-related osteonecrosis of the jaws (MRONJ) is an adverse side effect of several drug therapies, including bisphosphonates (BPs). Osteonecrosis of the jaw specifically related to BP therapy is usually referred to using the acronym BRONJ. However, no consensus has yet been reached regarding the most appropriate management of BRONJ. The greatest success rates have been recorded with surgical removal of necrotic bone. In particular, erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted surgery has shown significantly better results than conventional surgical approaches...

BACKGROUND: Ablative fractional erbium-doped yttrium aluminum garnet (Er:YAG) laser and microneedling have been popularized in recent years and their effectiveness and side effects individually reported. No previous study, however, has directly compared the efficacy and safety between the 2 different treatments. OBJECTIVE: To compare the efficacy and safety of the ablative fractional Er:YAG laser and microneedling for the treatment of atrophic acne scars. MATERIALS AND METHODS: Thirty patients with atrophic acne scars were randomly treated in a split-face manner with a fractional Er:YAG laser on one side and microneedling on the other side...

The aim of the present study was to compare dynamics of the bone healing process after different types of osteotomies. In total, 24 Wistar rats were subjected to different types of osteotomy performed with standard steel bur, piezosurgery, contact, and non-contact Erbium:yttrium-aluminum-garnet (Er:YAG) laser ablation. The animals were randomly divided into four groups, to be euthanized immediately after the procedure, or at 1, 2, or 3 weeks after surgery. The obtained bone samples were analyzed by scanning electron microscopy (SEM)...

OBJECTIVES: The aim of this in vitro study was to evaluate the efficacy of different irrigation techniques including laser-activated irrigation using an erbium:yttrium-aluminum-garnet (Er:YAG) laser with a novel tip design (photon-induced photoacoustic streaming (PIPS)), Er:YAG laser with Preciso tip, sonic activation, and passive ultrasonic activation on the final irrigation solution penetration into dentinal tubules by using a laser scanning confocal microscope. MATERIAL AND METHODS: In this study, 65 extracted single-rooted human mandibular premolars were instrumented up to size 40 and randomly divided into 5 groups (n = 13) based on the activation technique of the final irrigation solution as follows: conventional irrigation (control group), sonic activation, passive ultrasonic activation, Er:YAG-PIPS tip activation, and Er:YAG-Preciso tip activation...

Topical anaesthetic cream (TAC) is commonly used as a pre-treatment of ablative fractional resurfacing (AFR) laser. Most of anaesthetic cream contains distilled water as major component. Therefore, pre-operative TAC may interfere the photothermal reaction in the skin treated with fractional carbon-dioxide (FCO2) laser and fractional erbium-doped yttrium aluminium garnet (FEr:YAG) laser. The objective of the study was to compare the ablative width (AW) and coagulative depth (CD) of AFR laser with and without pre-treatment with TAC...

Rosacea is characterised by a wide variety of vascular changes. Apart from telangiectasia and erythema, often so-called flushing occurs. These vascular abnormalities can be targeted with specific light and laser devices. In addition to KTP laser, pulsed dye laser (PDL) and Nd:YAG laser, also intense pulsed light devices (IPLs) are used. The described therapeutic effects include the reduction of vascular abnormalities and even improvement of papulopustular changes. While the KTP laser shows very good results in telangiectasia, the dye laser and IPL devices are used preferably in erythema...

Die Rosazea ist durch vielfältige vaskuläre Veränderungen gekennzeichnet. Neben Teleangiektasien und Erythemen treten häufig auch sogenannte "Flushings" auf. Haupteinsatzgebiete von Licht- und Lasersystemen sind diese vaskulären Veränderungen, wie Erytheme und Teleangiektasien. Neben dem KTP-Laser, dem Farbstofflaser (PDL) und dem Nd:YAG-Laser kommen auch Blitzlampen (IPL) zum Einsatz. Neben der Rückbildung der vaskulären Komponente, ist auch eine Verbesserung der papulopustulösen Komponente beschrieben...

INTRODUCTION: Maxillary transverse deficiency (MTD) is one of the most pervasive and common skeletal problems in the craniofacial complex. This study aimed to evaluate the effect of associating the application of Erbium-YAG laser with rapid maxillary expansion (RME) for treating MTD in young adult patients with permanent dentition in regard to skeletal and dental effects. METHODS: Twenty-four subjects, aged from 15.5 to 19 years and needing RME as a therapeutic procedure, were randomly assigned to either the laser group (n=12) or the control group (n=12)...

BACKGROUND: Several lasers have been used for the treatment of xanthelasma palpebrarum (XP), such as Q-switched Neodymium:Yttrium Aluminium Garnet (QSNd:YAG), Erbium:Yttrium Aluminium Garnet (Er:YAG) laser. However, there is no comparemental study among these laser options in the treatment of XP. OBJECTIVE: The aim of this study was to compare the clinical efficacy and response rates of QSNd:YAG and Er:YAG in the treatment of XP. METHODS: Sixty patients with a total of 102 XP lesions were randomly and equally divided into two groups...

This study evaluated the degree of endodontic smear layer removal using the Er:YAG PIPS technique (2.94 μm) in comparison with different irrigants. Sixty-four single-rooted teeth were endodontically prepared up to size #40 and were divided into 8 groups (a-h) (n = 8). Groups a, b, c, and d were irrigated with (3 % NaOCl + 20 % EDTA), (0.9 % NaCl), (3 % NaOCl), and (20 % EDTA), respectively. Groups e, f, g, and h were treated with (3 % NaOCl + 20 % EDTA + PIPS), (0.9 % NaCl + PIPS), (3 % NaOCl + PIPS), and (20 % EDTA + PIPS), respectively...

BACKGROUND: Despite considerable improvements in oral health, dental caries continue to be a public health issue. The most frequently used, and universally accepted technique, to remove caries is through mechanical ablation of decayed tissues by means of rotating drills (diamond or tungsten carbide, or both). In the past few decades, the introduction of adhesive filling materials (resin composites) has affected cavity filling procedures by reducing its retention needs, with advantages for dental tissue conservation...

Scrotal calcinosis is a rare local entity characterized by multiple, calcified and painless nodules of the scrotal skin and was first described by Lewinski in 1883 (Figure 1a).(1) It normally appears in men aged 20-40 years.(2) For a long time, the pathological origin of this disease was unclear. In the last years it became more and more obvious, that dystrophic calcification of epithelial cysts involving inflammation, rupture, calcification and finally obliteration of the cyst wall is the main pathological correlate for scrotal calcinosis...

OBJECTIVE: Additional cleaning techniques and devices are required to remove maximum amount of residual filling material, which might limit disinfection of root canal system during retreatment. This study aimed to compare fracture resistance of roots when self-adjusting file (SAF), photon-induced photoacoustic streaming (PIPS), passive ultrasonic irrigation (PUI), erbium-doped yttrium aluminum garnet (Er:YAG), or neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers are applied following the use of retreatment files in endodontics...

Pearly penile papules (PPP) present as dome-shaped papules of no more than 3 mm in diameter that line the base of the glans of the penis. These benign lesions affect between 14.3 and 48 % of men. While often asymptomatic, PPP can cause a great deal of psychological distress that may warrant treatment. Current treatment options include cryotherapy, electrodessication, and curettage (ED&C). However, these modalities may have considerable adverse cosmetic effects, including scarring, pain, and pigmentary changes...
