A total of 224 children aged 5-8 years who needed at least two restorative dental treatment of the mandibular first primary molar were included in the study.~In each sessions the Wong-Baker FACES Pain Rating Scale (W-BFRS) was used to evaluate the dental anxiety before and after the treatment.~The Modified Corah's Dental Anxiety Scale (MDAS) was used as a dental anxiety measurement method.~A portable finger pulse oximeter (Nellcor™ PMN10, Medtronic Corp. MN, USA) was used to measure the heart rate.~Data were statistically analyzed with the help of the Statistical Package for Social Sciences statistical software (SPSS 18.0), considering a 5% significance level. Nonparametric tests were used. Normality assumption was evaluated with the Kolmogorov Smirnov test. The association between two groups was analyzed by Wilcoxon Signed Rank Test.
Dental anxiety is defined as the fear of terrible events during dental treatment and the loss of control.Anxiety may be related to adaptation of the patient to external factors in environment, so the adaptation of the pediatric patient to the stimuli in the dental environment may affect the level of anxiety.The aim of the this study was to evaluate the relationship between sequential visits in dental treatments and dental anxiety levels of pediatric patients with anxiety scales and physiological measurements.
