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 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...

The aim of this study was to evaluate the sealing ability and marginal adaptation of calcium silicate-based cements (CSCs) in root-end cavities prepared by ultrasonic and laser tips. A total of 72 extracted human maxillary incisor teeth were randomly divided as 60 teeth in experimental groups and 6 teeth each for positive and negative control groups. Specimens in experimental groups were obturated, their root-end resections were performed and randomly divided into six groups (n = 10) as follows: G1: Ultrasonic retrotip + MTA, G2: Ultrasonic retrotip + Calcium Enriched Mixture (CEM), G3: Ultrasonic retrotip + Biodentine, G4: Er:YAG laser tip + MTA, G5: Er:YAG laser tip + CEM, G6: Er:YAG laser tip + Biodentine...

BACKGROUND: Dentin hypersensitivity is an important clinical problem affecting a large percentage of the population, and various therapies have been suggested for its treatment-among them desensitizing agents and lasers. The aim of this study was to evaluate the in vitro effects of different in-office desensitizing agents and different type lasers, alone or in combination, on human dentinal tubules. MATERIALS AND METHODS: Eighty-four dentinal specimens obtained from freshly extracted impacted third molars were included and subsequently divided into seven groups: Group 1 (Control), Group 2 (Gluma desensitizer), Group 3 (Teethmate desensitizer), Group 4 (Nd:YAG laser), Group 5 (Er:YAG laser), Group 6 (Gluma desensitizer + Er:YAG laser), and Group 7 (Teethmate desensitizer + Er:YAG laser)...

Structural characteristics of the vaginal mucosa in stress incontinence and its correction by IncontiLase technology were studied. Studies of vaginal biopsy specimens before the exposure showed degenerative and atrophic changes in the stratified squamous epithelium, disorganization of fibrillar structures of the intercellular matrix, and microcirculatory disorders. Studies after Er:YAG laser exposure showed signs of neocollagenogenesis and elastogenesis, foci of neoangiogenesis, reduction of epithelial degeneration and atrophy, and an increase of the fibroblast population...

INTRODUCTION: The tug of war to maintain tooth integrity is dependent on a ratio between demineralization and remineralization. Hence, demineralization should be retarded and remineralization should be enhanced to maintain a natural equilibrium in the oral cavity. AIM: To compare in-vitro acid resistance of human enamel when using Casein Phosphopeptides Amorphous Calcium Phosphate (CPP-ACP) [GC Tooth mousse] cream, Casein Phosphopeptide Amorphous Calcium Fluoride Phosphate (CPP-ACFP) [GC Tooth mousse plus] cream, Er:YAG laser alone, combination of CPP-ACP with Er:YAG laser, CPP-ACFP with Er:YAG laser...

This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration...

OBJECTIVE: The purpose of this study was to evaluate the effects of laser and acid etching on the mineral content and photon interaction parameters of dental enamel in human teeth. BACKGROUND DATA: The composition of dental enamel may vary, especially at the surface, depending on the reactions that occur during dental treatment. MATERIALS AND METHODS: Forty maxillary premolars were divided randomly into 2 groups of 20 teeth. In the first group, half of teeth crowns were etched by using 37% phosphoric acid; in the second group, half of teeth crowns were etched by using an erbium:yttrium-aluminum-garnet (Er:YAG) laser...

This study was conducted in order to compare clinical and histopathological outcomes for excisional biopsies when using pulsed CO2 laser versus Er:YAG laser. Patients (n = 32) with a fibrous hyperplasia in the buccal mucosa were randomly allocated to the CO2 (140 Hz, 400 μs, 33 mJ) or the Er:YAG laser (35 Hz, 297 μs, 200 mJ) group. The duration of excision, intraoperative bleeding and methods to stop the bleeding, postoperative pain (VAS; ranging 0-100), the use of analgesics, and the width of the thermal damage zone (μm) were recorded and compared between the two groups...

OBJECTIVES: To assess the long-term outcomes (>4 years) following combined surgical resective/regenerative therapy of advanced peri-implantitis lesions using two surface decontamination methods. MATERIAL & METHODS: Fifteen patients (n = 15 combined supra- and intrabony defects) completed a follow-up observation period of 7 years. The treatment procedure included access flap surgery, granulation tissue removal and implantoplasty at buccally and supracrestally exposed implant parts, and a randomly assigned decontamination of the unmodified intrabony implant surface areas using either (i) an Er:YAG laser (ERL) or (ii) plastic curettes + cotton pellets + sterile saline (CPS)...
