It sometimes happens that the data collected are only in rank form within each block or normality cannot be assumed in the randomized block design. In these situations, a nonparametric approach called the Friedman rank test can be utilized. The Friedman rank test is primarily used to test whether c sample groups (i.e., the treatment levels) have been selected from populations having equal media...

Objectives This study sought to compare the one-year clinical success of a hydrophilic and a hydrophobic fissure sealant in permanent first molars. Materials and Methods This split-mouth clinical trial was conducted on 23 six to nine year olds who had four fully erupted sound first molars. Helioseal-F and Embrace sealants were randomly applied on the first molars, and follow-ups were schedule...

BACKGROUND The aim of this clinical trial study was to clinically evaluate the use of enamel matrix protein derivative combined with the coronally positioned flap to treat gingival recession compared to the subepithelial connective tissue graft by a new method to obtain denuded root surface area. MATERIALS AND METHODS Thirteen patients, each with two or more similar bilateral Miller class I o...

Since Friedman's discovery5 in 1929 that urine from pregnant women would induce ovulation when injected into young female rabbits, there have been several attempts to use the test with various other mammals. These are summarized by Snyder and Wislocki8 and by Schultz and Snyder.7 Reports of experimental and clinical observations on the use of the Friedman test for diagnosis of pregnancy are ver...

METHOD This was a quasi-experimental, nonequivalent, control group design study. A sample of 30 consenting participants was selected from an urban, community psychiatric clinic, and ...

In this controlled prospective clinical study the highly viscous glass ionomer cement Ketac Molar was clinically assessed in Class I and Class II cavities. Forty-nine subjects (mean age 32.3 years) received 108 restorations placed by six operators in conventional Black I and II type cavities with undercuts after excavating primary lesions or after removing insufficient restorations. At baseline...

The Friedman (1939) test for pregnancy has the minor disadvantages that skill is required for the intravenous injection into the ear vein of the rabbit and that some 3 % (Albert, 1949; Evans and Krajian, 1944) of urine samples are toxic to the rabbit if injected intravenously. Ducey (1950) overcame some of these difficulties by injecting urine subcutaneously in doses of 20 to 30 ml. in the loos...
