Evidence from traditional service settings shows that service quality is a major driver of customer satisfaction, trust, and loyalty, which ultimately lead to profitability. Regarding business on the Internet, many argue that trust and loyalty become even more important for long-term success. But does quality play the same influential role in the context of Web-based services, where it is said that price is king and competitors just one click away? In the present study, the authors develop a structural equation model that links Web-based service quality to a broad set of consequences.The model is tested with a large sample drawn from three different Web-based service domains. The results provide insights into the mechanisms leading from Web-based service quality to outcome variables. Specifically, they point to a multifaceted chain of effects, with trust playing a key mediating role.

AimThe aim of this study was to evaluate the effects of calcium channel blocker (CCB) amlodipine (AML), platelet rich plasma (PRP), and a mixture of both materials on bone healing.Materials and methodsFifty-six male Wistar rats were randomly divided into four groups: group A, tibia defect model with no treatment; group B, tibia defect model treated with AML, 0.04 mg daily by oral gavage; group C, tibia defect model treated with local PRP; group D, tibia defect model treated with local PRP and AML, 0.04 mg daily by oral gavage.ResultsAt day 21, bone healing was significantly better in groups C and D compared to group A (P<0.05), but comparisons showed no statistically significant difference in group B (P>0.05). At day 30, groups B and C showed no statistically significant difference (P>0.05) compared to group A, but bone healing in group D was significantly better than in group A (P<0.05). Statistically, AML did not affect alkaline phosphatase (ALP) activity at 21 and 30 days (P>0.05), but PRP and AML + PRP increased ALP activity statistically (P<0.05).ConclusionIt can be concluded that AML had neither a positive nor a negative effect on bone healing, but when used in combination with PRP, it may be beneficial.

The aim of this article is to emphasize that the accidental displacement of a lower third molar during extraction is a rare, but potentially serious complication. We present two case reports on a lower third molar tooth dislodged into the submandibular space following its removal from the sockets and the subsequent management of this rare complication. Differences in the direction of displacement, the size of fragment, delay in retrieval, and tissue reactions can all influence this potential serious complication and hence no one technique is uniformly applicable. Though a rare complication, clinicians must be aware of possible lower third molars dislodgement into tissue spaces and the necessity to initiate prompt and appropriate management.

In dentistry especially as after the oral surgery may occur disorders such as pain, swelling and trismus. Certainly, many analgesic drugs are used to in order to control pharmacologically occurring the problems and the inflammatory process The aim of this review is to update the existing information about the utilization of pain medications and effectiveness used after oral surgery and examine the methods of implementation in the light of earlier studies.
