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...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

Background and purpose: Prevention of dental caries is one of the primary goals in dentistry. Application of fluoride decreased dental demineralization but the preventive ability of this fluoride is limited. Nowadays different investigations into dental erosion focused on the preventive effect of laser irradiation. The purpose of this applied study was to assess the effect of diode laser (&lamb...

Background and Aim: Bacterial disinfection is considered as the primary etiology of pulpal and periapical lesions and as the result, adequate elimination of such infections is one of the purposes of root canal treatment; But since this purpose is impossible to achieve, reducing the bacterial load seems to be as a rational goal. Diode lasers have made their way into endodontics for better disinf...
