Special Issue Information

Dear Colleagues,

The use of three-dimensional techniques in health care sciences is expanding exponentially, and has offered unique possibilities to clinicians and researchers.

In radiology, the introduction of cone-beam CT imaging has laid the foundation for three-dimensional diagnosis in patients where the use of conventional CT technology cannot be justified due to the high costs and the increased radiation exposure. For example, this is relevant to patients undergoing orthognathic surgery, patients receiving orthodontic treatment, patients in need of dental implants, and many more.

Three-dimensional scanners have allowed clinicians to record the anatomy of osseous and soft-tissue structures in order to potentially perform treatment simulations using specific software. Furthermore, three-dimensional printing has improved the manufacturing process, and thus the efficiency of custom-made medical/dental devices or other products that can be used for clinical applications.

Advancements in three-dimensional technology have also influenced the photographic assessment of faces. In health care sciences, where evaluations of the soft-tissue facial structures and of the patients’ appearance are fundamental for diagnosis and outcome assessment, the use of three-dimensional photography and facial scanning provide a superior solution compared to the standard two-dimensional photographs, because they allow facial analyses in three dimensions. This is also true in social sciences, where traits such as facial attractiveness and facial expressions are studied.   

Within this scope, I am pleased to invite you to submit your work to this Special Issue of Applied Sciences, focusing on the use of three-dimensional technology in health care.

This Special Issue aims to highlight articles that introduce new applications of three-dimensional technologies, assess the reliability of current three-dimensional methods, or compare two- to three-dimensional tools for patient diagnosis and outcome assessment. Preferably, submitted articles should be of specific interest for medical and dental specialists, and for specialists in psychosocial sciences.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

- Orthodontics
- General Dentistry
- Radiology
- Orthognathic Surgery
- Dental Implantology
- Prosthetic Dentistry
- Endodontology
- Psychology
- Sociology
- Biomedical Engineering

I look forward to receiving your contributions.

The present study aimed to analyze the gender dimorphism in odontometrics of permanent maxillary canines using a three-dimensional digital method and to test the accuracy in gender estimation using discriminant function analysis in a sample of the Saudi population. A total of 120 diagnostic dental casts of patients aged 16–29 years were used in the present study. Plaster models of their maxillary dentition obtained from the archives were scanned and digitally measured using a three-dimensional digital method. The mesiodistal width of the right and left maxillary canines and intercanine distance were measured. Gender dimorphism was established using the Garn method. Data were statistically analyzed using descriptive statistics, the Mann–Whitney U test and discriminant analyses. Males showed larger mean dimensions of canines than females with regard to both mesiodistal width and intercanine distance, and the difference was statistically significant (p < 0.05). The right maxillary canine mesiodistal width showed a higher percentage of gender dimorphism (3.5%). Discriminant function analysis showed that the overall accuracy of gender prediction was 80.5% for the multivariate analysis. The univariate discriminant function equation revealed that intercanine distance was the most accurate predictor of gender (78%), followed by the right canine mesiodistal width (76.3%). The use of three-dimensional technology for odontometrics presents a promising method, and permanent maxillary canine parameters can be used as an acceptable ancillary tool for gender estimation in forensic science.

The cranial base has a crucial effect on the position of the maxilla and mandible. This study aims to investigate the relationship between the cranial base sagittal and transverse dimensions in different skeletal patterns. This is a retrospective study of pre-existing CBCT images of 132 subjects (60 males and 72 females) from Saudi Arabia with a mean age of 35 years old. The grouping of the subjects was based on the ANB angle of Steiner’s analysis. One-way ANOVA was used to compare the means of the sagittal and transverse dimensions between different skeletal patterns, followed by a post hoc test for individual comparisons. Logistic regression analysis was performed to test the relationship between gender, age, and cephalometric values between the three groups. The significance level was 0.05. One-way ANOVA revealed a statistically significant difference in posterior cranial base length (p < 0.05) and total cranial base length (p < 0.05) among different skeletal patterns. Tukey’s post hoc analysis showed that skeletal class II had a smaller posterior cranial base and total cranial base length when compared to the other groups. The class II skeletal pattern has a smaller posterior cranial base and total cranial base when compared to skeletal class I and class III skeletal patterns. Full article
