The recent study aimed to evaluate the knowledge levels of dentists on intraoral scanners and 3D printers with their usage prevalence of them in Türkiye.A link to the survey was sent via e-mail to 1782 dentists in different branches who participated in this survey, which had 27 questions in four subgroups, including demographic information, general digital dentistry, intraoral scanners, and 3D printers. The total number of dentists who answered the questionnaire was determined as 305. Considering the distribution of the ages, %21.3 (n=65) of the participants were 23-28 years, %32.1 (n=98) were 29-35 years, and %46.6 (n=142) were 36 and over years. A statistically significant difference was found in the use of intraoral scanners and 3D printers in workplaces (p<0.001, p<0.001). A statistically significant difference was found regarding branches in intraoral scanner usage. While the rate of using intraoral scanners by 54.5% of restorative dentists is higher than other branches (p<0.001), orthodontists were found to be more active users of 3D printers (47.9%, p=0.001). According to the results of our study, it has been observed that dentists generally obtain information about intraoral scanners and 3D printers through individual efforts and only a few dentists in Türkiye can integrate these devices into their everyday practices.

The objective of this study is to evaluate the trabecular structure in hypodivergent individuals using fractal analysis, with a particular focus on specific mandibular regions. This study aims to assess the impact of hypodivergent growth patterns on bone microarchitecture. This research involved a methodological approach using panoramic radiographs to assess trabecular structure at specific regions of the mandible using fractal analyses. The dimensions of the fractals were calculated with the use of the box-counting technique by the software Image J (v1.53c; Bethesda, MD, USA, National Institutes of Health), while the statistical evaluations were carried out with the Jamovi Software (The Jamovi Project, version 2.3.21.0). The study found significant differences in fractal dimension values between hypodivergent individuals and the control group, particularly in the condyle and angulus regions, indicating a less complex trabecular structure in hypodivergent individuals. This study concludes that individuals with a hypodivergent growth pattern exhibit alterations in trabecular bone structure within the mandibular condyle and angulus regions, characterized by reduced complexity. These findings suggest that increased occlusal forces and mechanical stress associated with this growth pattern may contribute to changes in trabecular architecture. Understanding these variations is essential for orthodontic and maxillofacial diagnosis, treatment planning, and biomechanical considerations, particularly in cases requiring vertical dimension management or anchorage control.

Background: This study aimed to evaluate the torque effectiveness of different attachment types and power ridges used in clear aligner therapy (CAT) on the upper lateral incisors. Methods: A typodont model simulating oral conditions was developed. Two hundred lateral incisor samples were divided into five groups based on attachment types and clear aligner modifications: no attachments (NA), horizontal ellipsoid attachment (HEA), vertical ellipsoid attachment (VEA), buccal power ridge (BPR), and buccal and palatal power ridge (BPPR). Subsequently, a 5° palatal torque moment was applied to the lateral incisors. In-house clear aligners were inserted, and 3D scanning was performed after each aligner step. Post-treatment 3D models were compared with pre-treatment models. The lateral incisors were assessed for torque, tipping, and rotational movements. Results: The HEA group (41.6%) and the BPPR group (40.8%) showed significantly higher torque effectiveness than the NA group (20%) when 5° of torque was delivered. The planned movement was approximated when 1° and 2° of torque were applied in the NA group (114% and 98%, respectively). The NA and BPR groups showed the highest loss of anchorage. Conclusions: When more than 3° of torque was applied, HEA and BPPR were more effective than NA in achieving the CAT’s planned torque of the upper lateral incisors, although with an efficacy rate of approximately 40%. Highlights: It is challenging to achieve torque movement using CAT. When less than 3° of torque was required, additional mechanics were not necessary. BPPR and HEA showed higher effectiveness when 5° of torque was applied. The efficacy of BPR was similar to that of NA.

Objective: The purpose of this study is to investigate the apparent trends in cleft lip and palate (CLP) studies published over the last 10 years, and assesses the effectiveness of the studies. Materials and Methods: The SCImago Journal Rank (SJR) data were utilized to select the journals with a high SJR indicator in each of the orthodontics, pedodontics, general dentistry, speech therapy, clinical genetics, pediatrics, plastic esthetic and reconstructive surgery and oral surgery areas. CLP-related studies were identified in the databases accessed through Web of Science owned by Clarivate Analytics. The articles were assessed in terms of year of publication, journal title, specialty, article subject matter, affiliations of the authors, citation relationships and countries/regions of origin. A total of 2,696 CLP-related articles published over the last 10 years were identified based on our search criteria. Results: The analysis revealed that the most prominent keywords were “palatoplasty”, “alveolar bone grafting”, “distraction osteogenesis” and “orthognathic surgery” among the treatment procedures. The most common WoS categories among the articles were dentistry, oral surgery & medicine, and surgery. The most cited publications over the last decade have included such terms as “environmental risk factor”, “GRHL3”, “FGFR2”, “loci”, “candidate gene” and “BMP”. Conclusion: Recent CLP articles in the literature have focused mainly on treatment procedures, with the most-cited articles generally containing evaluations of the relationship between CLP and genetics. More recent methods have been discussed in only a limited number of studies.
