Escherichia coli and Staphylococcus aureus bacterial retention on mirror-polished and ultrashort pulse laser-textured surfaces is quantified with a new approach based on ISO standards for measurement of antibacterial performance. It is shown that both wettability and surface morphology influence
OBJECTIVE
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
OBJECTIVE
The diode laser combined with Er:YAG laser is a new treatment modality for acute sialadenitis. A 78-year-old woman with acute suppurative parotitis was treated by traditional probe to the duct orifice with oral antibiotics for 2 weeks. The symptoms and signs did not subside after
The investigation had the purpose to study the lethal effect of laser infrared radiation (1220-1320 nm) on various genotypes of E. coli K-12 cells. Laser was produced by a parametric LiNbO3 light generator pumped up by the NdYAG second harmonic radiation. Results were compared with effects of X-ray
A laser-spinning technique has been used to produce amorphous, dense and flexible glass nanofibers of two different compositions with potential utility as reinforcement materials in composites, fillers in bone defects or scaffolds (3D structures) for tissue engineering. Morphological and
Tattoos are placed for different reasons. A technique for tattoo removal which produces selective removal of each tattoo pigment, with minimal risk of scarring, is needed. Nonspecific methods have a high incidence of scarring, textural, and pigmentary alterations compared with the use of Q-switched
OBJECTIVE
The aim of this study was to compare the bactericidal effect of various laser irradiation systems on Enterococcus faecalis biofilms in dentinal tubules by using a novel dentin infection model and confocal laser scanning microscopy (CLSM).
BACKGROUND
Laser-activated irrigations have been
OBJECTIVE
To evaluate the 'in vitro' bactericidal effect of the Nd:YAG laser (Genius, MØlsgaard Dental, Copenhagen, Denmark) on six periodontal pathogens.
METHODS
Suspensions of six different periodontal pathogens (Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Prevotella
Objective: This study aims to compare the bactericidal efficacy of different Er,Cr:YSGG disinfection methods, particularly combined application of Er,Cr:YSGG and Diode laser. Background: Root canal disinfection is important for long-term endodontic success. Different laser systems are
The effects of laser energy on three bacterial strains, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa were studied utilizing the neodymium:YAG laser. Cell suspensions of each strain were divided into four groups. In group I, suspensions from each strain were exposed to laser
OBJECTIVE
Recently Erbium (Er) YAG laser has been developed for dentistry. It may be suitable for periodontal therapy. This study examined the bactericidal effect of the Er: YAG laser on periodontopathic bacteria in vitro.
METHODS
After spreading the bacterial suspension of Porphyromonas gingivalis
The aim of this study was to compare the antibacterial activities of Er,Cr:YSGG laser with two different power outputs against a chlorhexidine gluconate-based cavity disinfectant. A cavity tooth model test was used to determine the antibacterial activity. Four cylindrical cavities were prepared on
The bactericidal effects of lasers with wavelengths of 1.67 and 2.94 µm on cariogenic Streptococcus mutans were investigated. Temperature during irradiation was also measured to determine the mechanism underlying the bactericidal effects of the lasers. An aliquot of 2 µl cell suspension of S. mutans
A method for evaluation of serum bactericidal activity against S. aureus by laser flow cytofluorometry has been developed and proposed for clinical application. This method was used to study the overall bactericidal activity of donors' sera and to estimate the contribution of complement to the
