OBJECTIVES: To assess the long-term clinical outcomes following nonsurgical therapy of peri-implant diseases at two-piece zirconium implants. MATERIAL & METHODS: A total of 27 patients suffering from either (i) peri-implant mucositis (n=24 implants) or (ii) peri-implantitis (n=16 implants) completed a mean follow-up period of 32.8±2.85 months (median: 34 months). The initial treatment procedures included (i) mechanical debridement + local antiseptic therapy using chlorhexidine digluconate (MD+CXH), or (ii) Er:YAG laser monotherapy (ERL)...

OBJECTIVE: The risk of extrusion of irritative irrigants into the extraradicular tissue should be minimized during root canal irrigation. This study aimed to examine the pressure generated outside the apex during Er:YAG laser-activated irrigation (LAI) in comparison with passive ultrasonic irrigation (PUI) and conventional syringe irrigation (SI). BACKGROUND DATA: LAI is reported to be efficient for root canal debridement, whereas the apical pressure generated during LAI has not been investigated in detail...

OBJECTIVE: The objective was to compare the efficacy of three different lasers in disinfection of root canals inoculated with Enterococcus faecalis and Candida albicans biofilms. BACKGROUND: Endodontic space disinfection depends on the type of root canal irrigant used and the way it is delivered and agitated because irrigants have limited ability to reach all parts of root canal system. MATERIALS AND METHODS: Thirty single-rooted human teeth were selected...

The passively Q-switched Er:YAG laser at 1.6 μm was achieved with a YAG-based MoS<sub>2</sub> saturable absorber (SA) for the first time. The saturable absorption properties of the MoS<sub>2</sub> SA near 1.6 μm were investigated. Under an absorbed pump power of 8.09 W, an average output power of 1.08 W with a pulse duration of 1.138 μs and a repetition rate of 46.6 kHz was obtained, corresponding to an optical conversion efficiency of 40.67%. The pulse energy and peak power were calculated to be 23...

BACKGROUND: Scar management using laser phototherapy continues to evolve as it gains wide acceptance among patients and providers. Despite widespread use of laser therapy, there are no guidelines or consensus published regarding optimal pre- and post-procedure patient management. Our objective is to gain insight into the best laser practices; we decided to poll colleagues nationwide. METHODS: An online survey was distributed to members of the American Society of Plastic Surgeons...

REVIEW
Marco Gambacciani, Santiago Palacios
Laser therapy has a therapeutic role in various medical conditions and most recently has gained interest as a non-hormonal treatment for genitourinary syndrome of menopause (GSM) and as a non-invasive option for stress urinary incontinence (SUI). Several therapies are available to alleviate GSM symptoms, including hormonal and non-hormonal products. Both microablative fractional CO2 laser and the non-ablative vaginal Er:YAG laser (VEL) induce morphological changes in the vaginal tissues, and data from non-randomized clinical trials suggest that laser therapy can alleviate vaginal dryness and dyspareunia...

To evaluate the cleaning ability of Er:YAG laser against Enterococcus faecalis in root canals.
 Methods: The single-rooted human teeth were sterilized and inoculated with Enterococcus faecalis and were randomly assigned into 2 groups. A group of teeth was irrigated with saline during root canal preparation while another group with NaClO. After mechanical preparation, the two groups were randomly divided into 3 subgroups according to the different treatments: Samples, laser radiation, and calcium hydroxide intracanal medication for 7 days...

Acne is a chronic disease of the pilosebaceous units, presenting as inflammatory or noninflammatory lesions, affecting primarily the face but also the back and chest. The mainstay of treatment remains topical retinoids, benzoyl peroxide, azelaic acid, antibiotics, and isotretinoin, many of which result in poor compliance, lack of durable remission, and incur adverse effects. The use of lasers to treat acne is continuously increasing because of their minimal complications, limited number of office-based treatments required, potential benefits of simultaneously treating acne scarring, and the rapid onset of results...

The aim of this study was to evaluate the effect of Er:YAG laser irradiation on the micro-shear bond strength of self-etch adhesives to the superficial dentin and the deep dentin before and after thermocycling. Superficial dentin and deep dentin surfaces were prepared by flattening of the occlusal surfaces of extracted human third molars. The deep or superficial dentin specimens were randomized into three groups according to the following surface treatments: group I (control group), group II (Er:YAG laser; 1...

BACKGROUND: The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planing with hand instruments in non-surgical treatment of chronic periodontitis. MATERIAL AND METHODS: Twenty-five systemically healthy patients with chronic periodontitis were selected for this study. The quadrants were randomly allocated in a split-mouth design to either combined Er:YAG (160 mJ/pulse, 10 Hz) and Nd:YAG laser (100 mJ/pulse, 20 Hz) therapy (test group) or scaling and root planing alone (control group)...

PURPOSE: To evaluate the efficacy of conventional acid etching alone (acid etching) and Er:YAG laser combined with acid etching (laser + acid etching) on fissure sealant (FS) retention of first permanent molars (FPMs) after 18 months. MATERIALS AND METHODS: Using a split-mouth design in 51 children, a total of 204 FPMs were sealed with acid etching alone or laser plus acid etching (laser+acid). The retention of sealants and occurrence of caries were evaluated at 3, 6, 12, and 18 months...

The aim was to evaluate the surface roughness and bacterial adhesion on enamel irradiated with high intensity lasers, associated or not to a fluoride varnish. Eighty fragments of bovine enamel were equally divided in 8 groups (n=10). Group 1 was not treated and Group 2 received only a 5% fluoride varnish application. The other groups were irradiated with an Er:Cr:YSGG (8.92 J/cm2), an Nd:YAG (84.9 J/cm2) and a diode laser (199.04 J/cm2), associated or not to a 5% fluoride varnish. The surface roughness was measured before and after treatments...
