Gallium Arsenide Aluminium Laser in Esthetic Dentistry

Gallium Arsenide Aluminium Lasers in the Value Addition of Smile

Dental esthetics refers to the many scientific and artistic principles that considered collectively can create a beautiful smile. It deals with maintaining the harmony of the teeth and gingiva in relation to the face. Gingival health and appearance are the primary components for an attractive smile. Large numbers of young patients are concerned with disproportionally small teeth and gingival hy...

Effect of gallium-arsenide laser, gallium-aluminum-arsenide laser and healing ointment on cutaneous wound healing in Wistar rats.

This study determined the effects of gallium-aluminum-arsenide laser (GaAlAs), gallium-arsenide laser (GaAs) and Dersani healing ointment on skin wounds in Wistar rats. The parameters analyzed were: type I and III collagen fiber concentrations as well as the rate of wound closure. Five wounds, 12 mm in diameter, were made on the animals' backs. The depth of the surgical incision was controlled ...

Progress to a Gallium-Arsenide Deep-Center Laser

Although photoluminescence from gallium-arsenide (GaAs) deep-centers was first observed in the 1960s, semiconductor lasers have always utilized conduction-to-valence-band transitions. Here we review recent materials studies leading to the first GaAs deep-center laser. First, we summarize well-known properties: nature of deep-center complexes, Franck-Condon effect, photoluminescence. Second, we ...

Laser-assisted gingival tissue procedures in esthetic dentistry.

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 ...
