OBJECTIVE The purpose of this study was to evaluate the effect of tooth coating material and finishing agent on bleached enamel surfaces after using KTP laser with 27% hydrogen peroxide. BACKGROUND DATA There have been few reports on the effects of tooth coating materials and finishing agents after bleaching. METHODS After 40 crowns of human extracted maxillary incisors were bleached by KTP...

Objectives: To evaluate the efficacy and safety of photoselective vaporization of prostate (PVP) using a 100W potassium titanyl phosphate (KTP) laser in comparison to transurethral resection of prostate (TURP) in patients of benign prostatic enlargement (BPE). Materials and Methods: Between Jan 2014 and December 2015, 121 patients satisfying the eligibility criteria underwent surgery 62 PVP (Gr...

Crimes against property without using violence, in this case, are theft and burglary is the type of crime that most common every year. However, home security needs a system more efficient practical. To overcome this, an internet things (IoT) needed. This research evaluated performance prototype by reading distance from radio frequency identification (RFID) reader E-KTP quality service (i.e thro...

INTRODUCTION Oral biopsy aims to obtain clear and safe diagnosis; it can be performed by scalpel or laser. The controversy in this latter application is the thermal alteration due to tissue heating. The aim of this study is the histological evaluation of margins of "in vivo" biopsies collected by diode and KTP lasers. MATERIAL AND METHODS 17 oral benign lesions biopsies were made by diode 808...

We report a synchronously pumped optical parametric oscillator that generates the sum frequency of the pump and the signal wavelengths. A single KTiOPO4 (KTP) crystal is used for both parametric generation and sumfrequency generation in which these two processes are simultaneously phase matched for the same direction of propagation. The parametric oscillator, pumped by a femtosecond Ti:sapphire...

The treatment of chronic periodontitis consists of conventional mechanical debridement and removal of plaque and calculus'. Topical NSAIDs could be used to complement the therapy as an adjunct to resolve the inflammatory process and clinical signs of the disease more rapidly. A randomized clinical trial was performed on 33 systemically healthy patients diagnosed with chronic periodontitis, aged...
