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.

The objective of this study was to evaluate potential morphological changes in the brain tissue of patients with severe obstructive sleep apnea syndrome (OSAS) in comparison with normal subjects by using T1-weighted magnetic resonance imaging (MRI) technique. ⋯ The findings of our study indicated that even if severe, no structural changes occur in the course of mild, moderate, and severe OSAS.

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.

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.

One-third of patients newly diagnosed with a kidney tumor have metachoronous disease, 25-50% have synchronous metastasis, and approximately 30-40% of patients have metastasis at the time of diagnosis. Metastasis mostly occurs in the lungs, regional lymph nodes, bones, and liver. The present study was aimed to determine the effect on mortality the values of standard uptake value (SUV)max measured with positron emission tomography (PET) in metastases of kidney tumors. ⋯ In the present study, it was concluded that the higher the SUVmax value the shorter the survival time. The survival time of patients with metastasis was shorter, and this could be estimated through the measured SUVmax values.
