This in vitro study aimed to compare the cyclic fatigue resistance of HyFlex EDM (HEDM), Vortex Blue (VB), ProTaper Gold (PG), and OneCurve (OC) nickel-titanium (NiTi) instruments. ⋯ Within the limitations of this in vitro study, it was found that the cyclic fatigue resistance was higher for the HEDM instruments than for the VB, PG, and OC instruments.

The first aid implemented just after the traumatic dental injury (TDI) is of vital importance. This study aims to evaluate the attitudes of emergency medical technicians (EMTs) and paramedics toward TDI and their levels of knowledge about the issue. ⋯ In conclusion, it was determined that the EMTs and paramedics did not have sufficient and accurate information about the TDI. Lack of knowledge about TDI prevents rapid and accurate intervention to the cases.

The incidence of traumatic dental injuries is affected by social, environmental, and socioeconomic variables. For this reason, epidemiological studies are an important tool for increasing social consciousness and guiding the necessary precautions about trauma. ⋯ Early intervention is important for the prognosis of the injured tooth. However, except for severe injuries, the rate of referral to the clinic after trauma was low. Therefore, the level of social awareness and knowledge of trauma should be increased.

The aim of this study was to compare to effect of phototherapy and surface flattening after immediately bleaching on the shear bond strength to bleached enamel. ⋯ The present study showed that surface removal and phototherapy have a potential clinical application for eliminate to undesirable effect of bleaching treatment. Surface conditioning with either flattening and/or phototherapy may provide clinicians to restore bleached teeth at the same visit with bleaching and reduce chair-time.

Effect of laser application on microtensile bond strength of an orthodontic adhesive to water-aged composite.
This study evaluated the microtensile bond strength (MTBS) of an orthodontic adhesive to water-aged composite surfaces using different surface treatments. ⋯ An Er,Cr:YSGG laser application may be a feasible alternative to diamond bur for enhancing the bond strength of orthodontic adhesive to composite resin.
