Platelet-rich fibrin (PRF) can be named as a natural fibrin-based biomaterial favorable to increasing vascularization and able to guide epithelial cell migration to its surface. The membrane has a significant positive effect on protecting open wounds and accelerating healing. Similar to PRF Ankaferd Blood Stopper (ABS) also has positive effects on wound healing. The aim of this study was to detect if we can improve known physical properties of PRF combining with ABS. This idea was based on the known mechanism of ABS in forming protein network without damaging any blood cells. Materials and Methods: A total of 25 adult rabbits used for collecting 5-7 ml of blood passively with the help of winged blood collection needle to the test tube. Collected samples were centrifuged at 3000 rpm for 10 min. Two similar samples obtained from each animal and one of the samples was placed in 20% ABS 80% saline solution for 5 min. Mechanical properties of the membrane samples were measured using Universal Testing Machine. Results: There is the statistically significant difference between PRF and ABS added PRF in elongation/mm (dL) and elongation/% at break values. Maximum force (fMax) and modulus values did not show any statistically significant differences. ⋯ ABS loaded PRF causes better physical properties. This combination seems to exhibit superior performance when used as a membrane barrier solely. Advanced studies can be done on biological properties of ABS loaded PRF, especially on tissue healing.

When examining the incidence of autism, however, children should not be considered independent of their parents, as this collection of disorders also affects the life of their family members. Having a disabled child affects the relationships with the family and friends, and the social and work life of families. The quality of life of these families is discussed in terms of financial aspects, health, support of family members, values, occupation, family relations, and individual support dimensions of developmental disabilities. However, there are very limited studies on the relationship between perceived social support and quality of life of parents of children with autism, and none of these has been conducted in Turkey. ⋯ Our results provide important insights into the family experiences of parents of children with autism, and may aid the development of appropriate interventions to further support them. Providing support and understanding families of children with autism and their experiences, nurses, doctors and health professionals can positively affect their health outcomes. Healthcare professionals should focus on determining the needs of families to accordingly plan and implement appropriate programs.

The objective of the study is to evaluate the effects of repeated bracket bonding on the color changes of tooth enamel after in vitro coloration. ⋯ Repeated bracket bonding does not have a negative influence on the enamel color change after in vitro coloration when compared with intact enamel surface and single bonding.

The aim of the present investigation was to evaluate the effect of autoclave polymerization method on the mechanical and dynamic mechanical properties of different polymethylmethacrylate denture base materials. ⋯ Autoclave polymerization provided higher polymerization temperatures compared with the conventional heat polymerization. Autoclave-polymerized acrylic resin specimens showed higher tensile strength values; however, this was not the case for the impact test results. Flexural strength of specimens was improved with autoclave polymerization. Glass transition temperature was increased with autoclave polymerization.

The purpose of this study was to evaluate the effect of periapical lesion size on the degree of mucosal thickening of maxillary sinus and thickness of apical bone using cone-beam computed tomography. ⋯ Results of the present study showed that Schneiderian membrane near the maxillary premolars and molars with apical lesions is not significantly thicker compared to teeth without apical lesions.
