introduction: the aim of this study was to evaluate the effect of dental surface treatment with erbium-doped yttrium aluminum garnet(er: yag), neodymium-doped yttrium aluminium garnet(nd: yag) and carbon dioxide laser  (co 2 ) lasers and sodium ascorbate to recently home bleached enamel by scanning electron microscope (sem). methods: thirty extracted human third molars were selected for this in...

BACKGROUND AND 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. STUDY DESIGN/MATERIALS AND METHODS After spreading the bacterial suspension of Porphyromonas gingivalis or Actinobacillus actinomycetemcomitans on agar plate...

Scars following trauma [1] is a cause of concern for many a patient. Various modalities have been used for the treatment of scars over the years. Corticosteroids, dermabrasion, surgical revision, chemical peeling, silicone gel application, pressure therapy, and radiation have been used with varying results [2]. Ablative lasers such as the carbon dioxide (CO2), erbium: yttrium-aluminum-garnet (E...

BACKGROUND Treatment of congenital melanocytic nevi (CMN) with intense pulsed light (IPL) has recently produced promising results. OBJECTIVE To evaluate the clinical and histological outcomes of small-to-medium sized CMN treated with IPL alone and in combination with erbium: yttrium-aluminum-garnet (Er: YAG) laser. METHODS We performed a retrospective chart review of 26 small-to-medium size...

In recent years, with the growing popularity of nautical sports, marine medicine becomes increasingly important. The most commonly associated cutaneous diseases are the sun burn and the tanning. The other aquatic dermatology includes water-induced pruritus, pain, eruptions, and contact dermatitis. Injuries by jellyfish stings, venomous fish, sponges, and coral are not uncommon. However, sea urc...

Aim. This study sought to compare the microleakage of three adhesive systems in the context of Erbium-YAG laser and diamond bur cavity procedures. Cavities were restored with composite resin. Materials and Methods. Standardized Class V cavities were performed in 72 extracted human teeth by means of diamond burs or Er-YAG laser. The samples were randomly divided into six groups of 12, testing th...
