STATİSTİCAL ANALYSİS 
 
Statistical analyses will be performed using SPSS Statistics for 
Windows, Version 22.0 software (IBMCorp., Armonk, NY, USA). 
Statistical analysis will be performed for patient data including 
descriptive statistics, frequency and other characteristics for all 
categories. Continuous data will be expressed as mean ± standard 
deviation. Continuous variables will be analyzed with Shapiro-Wilk 
and Kolmogorov-Smirnov tests to determine whether the data 
conform to normal distribution.  Continuous and normally distributed 
variables will be compared using Student T-test. Nonparametric tests 
will be selected when the data are not normally distributed.  
Categorical variables will be compared using the chi-square test. All p 
values will be two-sided and p≤0.05 will be considered statistically 
significant. 
G power calculation was made by considering similar studies and the 
power of the study was calculated as 80%. 
 
 
İNFORMED CONSENT 
 
I was informed by Specialist Dr. Zülfü Savaş that a medical research 
titled “Random Comparison of Nasal Endotracheal Tube and Spiral 
Tube for Nasotracheal Intubation in Pediatric Patients” would be 
conducted at Dicle University Faculty of Dentistry and the above 
information about this research was conveyed to me. After this 
information, I was invited to participate in such a study as a 
“participant”. 
If I participate in this study, I believe that the confidentiality of my 
personal information, which should remain between me and the 
physician, will be treated with great care and respect during this 
research. I have been given sufficient confidence that my personal 
information will be carefully protected during the use of the research 
results for educational and scientific purposes. I can withdraw from 
the study without giving any reason during the conduct of the study 
(However, I am aware that it would be appropriate to inform the 
researchers in advance that I will withdraw from the study in order not 

to leave them in a difficult situation) Also, provided that no harm is 
done to my medical condition, the researcher 
I may be excluded from the research. 
I do not assume any financial responsibility for the expenses to be 
incurred for the research. I will not be paid. I have been given the 
necessary assurance that any medical intervention will be provided in 
case of any health problem that may arise, whether directly or 
indirectly, due to reasons arising from the research application. (I will 
not be under any financial burden regarding these medical 
interventions). 
If I encounter a health problem during the research, I know that I can 
reach Specialist Dr. Zülfü Savaş at any time at the phone number 0531 
7013696 (mobile) and on the Dicle University Faculty of Dentistry. 
I do not have to participate in this research and I may not participate. I 
have not encountered any coercive behavior about my participation in 
the research. I also know that if I refuse to participate, this will not 
harm my medical care and my relationship with the physician. 
I have understood all the explanations given to me in detail. After a 
period of reflection on my own, I have decided to take part as a 
“participant” in this research project. I accept the invitation with great 
pleasure and willingness. 
 
I will receive a copy of this signed form sheet.
