İkinci Parmağın Dördüncü Parmağa Oranı (2D:4D); Dental Anksiyete için Bir Belirteç Olabilir mi?

Abstract

Objective: 2D:4D (the ratio of the second finger to the fourth finger) ratio has been used as a morphological marker in evaluating the relationship between androgen exposure in the prenatal period and developmental/neuropsychiatric disorders. Material and Methods: Ninety-one children between the ages of 5 and 10 years from whom teeth were to be extracted under local anesthesia were included in the study. Measurements were made of the second and fourth fingers of the children's right and left hands. At the end of the procedure, the physician was asked to evaluate the patient's dental anxiety levels using the Frankl Behavior Scale (FBS). Results: Based on the FBS, the right-hand 2D:4D ratio was 0.979±0.074 in patients who refused treatment, 1.000±0.044 in unwilling patients who could not cooperate, 1.017±0.043 in cooperative patients, and 0.980±0.020 in patients with interest (p=0.092). The left-hand 2D:4D ratio was 1.024±0.045 in patients refusing treatment, 1.006±0.046 in unwilling patients who could not cooperate, 1.018±0.054 in cooperative patients, and 0.983±0.025 in patients with interest (p=0.526). No relationship was found between successful extractions and 2D:4D ratios in children. Conclusion: As a result, no significant correlation was found between dental anxiety and 2D:4D of pediatric patients who are planned tooth extraction. It was determined that 2D:4D is not a morphological marker that we can use to predict dental anxiety in the preoperative period.
