A laser is a collimated single wavelength of light which delivers a concentrated source of energy. Soon after different types of lasers were invented, investigators began to examine the effects of different wavelengths of laser energy on oral tissues, routine dental procedures and experimental applications. Orthodontists, along with other specialist in different fields of dentistry, can now ben...

The aim of this clinical study was to describe the possibility of using the Nd:YAG laser device utilized in the dental offices to weld metals intraorally. The authors, before applying this technique "in vivo" on human subjects, tested the "in vitro" metal welding efficacy of dental Nd:YAG device firstly by interferometry, SEM, and EDS and subsequently by thermal camera and thermocouples in orde...

statement of problem: the achievement of a good and durable dentin/composite resin bond is an important task in restorative dentistry. the application of acid conditioners and dentin bonding agents is an accepted method to enhance this bond strength. pretreating of dentin surface by laser irradiation seems to be a supplemental way to obtain better results, since lased dentin is more roughened a...

A quiet revolution is taking place in dentistry through the progression and integration of wide-ranging biophotonics technologies into clinical practice and research. These advances can be broadly divided into three major areas: Diagnostics, Therapy and Device Design/Manufacturing. Given our current emphasis on precision dentistry, biophotonics-based approaches are very attractive, enabling tis...

In 1960, Theodore Maiman exposed a human tooth to his prototype Ruby laser. The emission wavelength of the laser at 633 nm (deep red visible light) offered no beneficial interaction with the tooth, with much of the energy transmitting the enamel and dentine with presumable attenuation by the pigmented pulpal tissue. The inconsistencies of laser-tissue interaction continue to pose some difficult...

Soft tissue lasers are increasing in popularity among clinicians in part due to their potential value in preprosthetic gingival procedures. The ability of soft tissue lasers to control moisture and facilitate hemostasis appears particularly promising for clinicians excising gingival tissues, performing esthetic crown lengthening, and using resective techniques for gingival troughing--and these ...

the main goal in endodontic treatment is to eradicate or at least reduce intraradicular microbial population to levels that are more compatible with periapical lesions healing process. since endodontic infections are polymicrobial in nature, intraradicular survival of endodontic microbiota and their pathogenic properties are influenced by a combination of their virulence factors. the purpose of...

Laser therapy has become one of the gold standards treatment in routine dentistry. In 1970s, CO2 lasers were first to be used oral surgery on soft tissues. Subsequently, other (Diode, Nd YAG, Er: Argon and Erbium) have also been periodontics, implantology, orthodontics restorative dentistry, as well for hard tissues, such bone, enamel dentin. The purpose this systematic review is analyze both t...

This chapter aims to describe the fundamental principles of the production of laser radiation. The focus is to convey a general understanding of the underlying physical phenomena without entering into a detailed mathematical formulation. Some practical aspects especially devoted to the use of lasers in the dentistry environment are also covered.

Laser technology has been developed rapidly in the last decade. New lasers with a wide range of characteristics are available now which are being used in various branches of dentistry. The application of these new technologies in endodontics has always been challenging. Today more experience and knowledge in applying lasers in endodontics is available.
