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...

introduction: pyogenic granuloma (pg) is one of the inflammatory hyperplasia seen in the oral cavity. it is a reactional response to minor trauma or chronic irritation and also might be related to hormonal changes. rarely, pg occurs extragingivally.the most common treatment of pg is surgical excision but alternative approaches such as laser excision have also been proposed. case report : herein...

removal of smear layer and disinfection of canals are important objectives of teeth root canal cleaning. in order to achieve this purpose, rinsing substances, intra canal drugs as well as ultrasound are used. today, use of laser to remove smear layer and to disinfect root canals has increasingly attracted the attentions. till now different lasers such as co2, nd:yag, er:yag, er,cr:ysgg have bee...

introduction: in this study, arrangement of a low-cost optical tomography device compared to other methods such as frequency domain diffuse tomography or time domain diffuse tomography is reported. this low-cost diffuse optical imaging technique is based on the detection of light after propagation in tissue. these detected signals are applied to predict the location of in-homogeneities inside p...

Self-assembled InGaN quantum dots (QDs) have been grown using metalorganic vapor-phase epitaxy (MOVPE), without using antisurfactant. Using 120 s annealing, InGaN QDs have been successfully formed with a circular base diameter of 40 nm and an average height of 4 nm, with QDs density of 4 10 cm . The InGaN QDs have peak photoluminescence (PL) wavelengths of 519 and 509 nm for samples without and...

An organic semiconductor laser, simply fabricated by UV-nanoimprint lithography (UV-NIL), that is pumped with a pulsed InGaN LED is demonstrated. Molecular weight optimization of the polymer gain medium on a nanoimprinted polymer distributed feedback resonator enables the lowest reported UV-NIL laser threshold density of 770 W cm(-2) , establishing the potential for scalable organic laser fabri...

introduction: laser irradiation has been introduced in endodontic treatment due to its bactericidal effect. the aim of this study is to evaluate the bactericidal efficacy of a 940 nm diode laser alone or in combination with 5% sodium hypochlorite (naocl) against mature biofilms of e. faecalis . methods: sixty-eight (60 for the three groups, 4 for sem and 4 as negative controls) single-rooted hu...
