Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...

Background and Aim: Bleaching can improve the color of restorative materials and resolve problems related to discoloration or color mismatch. This study evaluated the effect of in-office bleaching method in conjunction with two different laser wavelengths on color change of two types of glass-ionomer restorative materials (light-cure and self-cure). Materials and Methods: In this experimenta...

Objectives The use of lasers for the treatment of periimplant hard and soft tissues is now refmore than ever before. Achieving bone integrity. The aim of this study is to evaluate the effects of Er:YAG, 980 nm and 810 nm diode lasers irradiation on biocompatibility of SLA titanium disks by SaOs2 cells morphology. Methods In this in-vitro study sixty sterile titanium disks with SLA surface were...

We describe an Er3+-doped aluminosilicate core photonic crystal fibre laser incorporating distributed Bragg reflectors written by two-photon 193nm irradiation through an optical phase mask as the feedback elements. The laser is diode pumped at 980nm and evidence of dual linewidth laser operation close to threshold is observed. However, at higher pumping levels gain competition preferentially se...

A frenum is a fold of tissue or muscle connecting the lips, cheek or tongue to the jawbone. Their high attachment may cause orthodontic problem (Central diastima), prosthodontic problems (Poor retention of denture), periodontic problems (gingival recession and inflammation) and speech problem (tongue tied in ligual frenum). A frenectomy is the removal of one of these folds of tissue and it is a...
