Objectives: The aim of this study was to establish whether a relationship exists between eye and hair color and orthodontic anomalies; an association has never been evaluated previously. Materials and Methods: The records of 406 adolescent patients to the Erciyes University Faculty of Dentistry for orthodontic treatment were included in this retrospective cohort study. Participants were divided into sagittal (Class I, Class II, and Class III) and vertical (low angle, normal angle, and high angle) skeletal malocclusion classes. Moreover, participants were also divided by their eye (brown, green, or blue) and hair (black, brown, or blonde) color. Collated data were statistically evaluated using the SPSS software by applying the one-way analysis of variance, Kruskal–Wallis, the Pearson Chi-square, and Fisher’s exact tests. Statistical significance was accepted at P < 0.05. Results: No statistically significant relationships were identified between sagittal and skeletal malocclusion and eye color (P > 0.05). However, the sella-nasion-b and CoGn parameters of brown-eyed individuals were significantly smaller than individuals with other eye colors (P < 0.05). Moreover, a statistically significant difference was established for the CoA, CoGn, and ANS-Me parameters between the different hair groups (P < 0.05). All three parameters were significantly lower in brown-haired individuals compared to individuals with black haired (P < 0.05). Conclusion: This study identified no significant association between the eye and hair color variable, with similarly formed craniofacial structures, and with the sagittal and vertical skeletal malocclusion. Therefore, any malocclusion estimation assumption formed based on either the hair or eye color of an individual will be incorrect.

Aims: The aim of this study is to evaluate the multidisciplinary treatment relationship between the two specialties of Dentistry, Departments of Periodontology and Orthodontics, by examining consultation request notes between the two departments. Materials and Methods: The consultation request notes of 1685 patients who were treated at Erciyes University Faculty of Dentistry were included in the study. All notes were analyzed retrospectively and divided into categories. While the consultation request notes of 446 patients from the Department of Periodontology (DP) to the Department of Orthodontics (DO) were evaluated, the consultation request notes of 1239 patients from DO to DP were evaluated. Pearson's Chi-Squared test was used in the cloud-based TURCOSA statistical software for the statistical analysis of the obtained data. Results: The highest number of requests for consultation from DP to DO was due to “Evaluation of the patient for orthodontic treatment (n = 203; 45.5%),” and the highest number of requests from DO to DP was “Gingival/Periodontal Treatment and Providing Motivation of Oral Hygiene (n = 558; 45.0%)“. It was observed that most patients for whom consultation was requested were women (P < 0.05). Conclusions: This study determined the most common reasons for consultation requests between DP and DO and the sex which was the most prevalent. It was concluded that requests were made for the expertise of the other department for problems that could not be solved by the first department.
