Comparative Study
Antimicrobial Effect of Toothpastes Containing Fluoride, Xylitol, or Xylitol-Probiotic on Salivary Streptococcus mutans and Lactobacillus in Children.
This in vivo study was designed to compare the antimicrobial effect of toothpastes containing fluoride, xylitol, or xylitol-probiotic on Streptococcus mutans and Lactobacillus in 13-15-year-old children. ⋯ In the light of the data obtained in this in-vivo study, a new innovational aspect has been reached in the use of probiotics to ensure the balance between bacterial flora in the oral cavity. In daily routine, the administration of probiotics to children is difficult. The toothpaste can be used as a vehicle to transport probiotics to children's mouth.

This study aimed to examine the microleakage of class V cavities of primary molars prepared by either a conventional dental bur or Er:YAG laser and one of two different adhesive systems. ⋯ Self-etch bonding systems and cavity preparation with Er:YAG laser may be an alternative to conventional restoration of primary molars with compomers. Further studies are warranted to fully elucidate the effect of laser-based etching techniques in cavities prepared by laser.

Beneficial Therapeutic Effects of Sildenafil on Bone Healing in Animals Treated with Bisphosphonate.
The purpose of the present study was to evaluate the effects of sildenafil on mandibular fracture healing in animals treated with zoledronic acid by using histologic, histomorphometric, immunohistochemical, and radiodensitometric methods. ⋯ Sildenafil may have positive effects on accelerating and improving fracture healing, and it may be used as a supporting factor in bone healing in patients treated with bisphosphonate (BP) to prevent negative effects of BP's.

Standard precautions (SPs) are crucial in protecting both health-care workers (HCWs) and patients from nosocomial infections. This study assessed the knowledge and practices of SP among HCWs in tertiary health-care facilities. ⋯ SP training and regular provision of PPEs are vital in compliance to SP.

The aim of this in vitro study was to compare the static cyclic fatigue resistance of thermal treated rotary files with a conventional nickel-titanium (NiTi) rotary file. ⋯ CM-Wire alloy represented the best performance in cyclic fatigue resistance, and NiTi alloy in R-Phase had the second highest fatigue resistance. CM and R-Phase manufacturing technology processed to the conventional NiTi alloy enhance the cyclic fatigue resistance of files that have similar design and size. M-wire alloy did not show any superiority in cyclic fatigue resistance when compared with conventional NiTi wire.
