Background: This study aimed to compare the reproducibility and reliability of the AI-supported WebCeph and app-aided OneCeph cephalometric analysis programs with a manual analysis method and to evaluate the analysis times. Methods: The study material consisted of pretreatment lateral cephalograms from 110 cases. Cephalometric analyses were performed manually, using the WebCeph program, and using the OneCeph application. A total of 11 skeletal, 6 dental, and 3 soft tissue parameters were measured. Cephalometric analyses of 30 randomly selected cases were performed again using three methods. The analysis times were recorded. Results: The WebCeph program and OneCeph application are highly compatible with the manual analysis method in terms of all parameters, except for SN measurement. It was found that the WebCeph program and the OneCeph application demonstrated moderate agreement in U1-NA distance measurement, while statistically high agreement was observed among all three methods for other dental parameters. It was determined that there was a moderate agreement among the methods in terms of nasolabial angle, whereas a statistically high level of agreement was found for the other soft tissue parameters. The analysis time was found to be the lowest in the WebCeph program and the highest in the manual analysis method. Conclusions: The WebCeph program and OneCeph application showed a high degree of compatibility with the manual analysis method, except for SN, SNA, Gonial angle, Articular angle, U1-NA distance and nasolabial angle measurements. Due to the higher correlation between OneCeph and the manual method, it can be concluded that the OneCeph application is the best alternative to the manual method.

Panoramic radiography is widely used for initial assessment during clinical examinations. It is very useful for clinicians to predict impaction of third molar teeth via certain parameters without relying solely on personal experience. This study aims to examine the relationship between the impaction of mandibular third molar teeth and mandibular morphology. Thus, mandibular third molar tooth impaction estimation can be provided with measurements made on panoramic radiography. The study material consisted of panoramic radiographs of 330 patients. The experimental group with impacted mandibular third molar teeth included 165 patients (mean age 20.62 ± 2.89 years), and the control group with erupted mandibular third molar teeth included 165 patients (mean age 22.23 ± 4.22 years). Nine dimensional, four angular, andone1 proportional parameter were examined on panoramic radiographs via the ImageJ program. The Mann‒Whitney U test, Kruskal‒Wallis H test, chi‒square test and correlation analysis were used for statistical analysis. Intraobserver reliability was examined via the intraclass correlation coefficient (ICC). Dimensional parameters such as condyle length, coronoid length, mandibular corpus width, sigmoid notch depth, retromolar space distance, and antegonial notch depth were significantly lower in the experimental group than in the control group. The Co/Cr angle was also significantly greater in the experimental group, whereas the alpha angle was significantly greater in the other groups. The ratio of the retromolar space distance to the third molar tooth width was also significantly greater in the control group. Mandibular third molar tooth impaction is related to various parameters of mandibular morphology. Certain measurements taken from panoramic radiographs may provide predictions regarding the likelihood of mandibular third molar impaction.

This study aimed to determine normative values for mesiodistal and buccolingual crown diameters of permanent teeth in the Turkish population and compare them with values reported in previous studies for other populations and the Turkish population. The mesiodistal and buccolingual diameters of permanent teeth were measured using digital calipers from dental cast models of 200 patients. The data analysis was conducted employing the SPSS 21 package software. The descriptive statistics were obtained for all parameters. Student t-test was utilized to compare the measurements between male and female patients. A paired t-test was used to compare the right and left side teeth. The significance level was set at 0.05. A total of 4800 teeth were measured. Men’s tooth sizes were larger than women’s tooth sizes. A stronger sexual dimorphism was observed in the buccolingual diameter in comparison to the mesiodistal diameter. No clinically significant differences were observed between antimeric teeth. In the maxilla and mandible, the first molars were found to have the largest mesiodistal and buccolingual diameters, whereas mandibular central teeth had the smallest diameters. Current norm values of mesiodistal and buccolingual diameters of permanent teeth in the Turkish population were established. The norm values presented are close to the tooth dimensions in studies carried out on other populations. Compared to previous studies, there is an increase in mesiodistal diameters in the Turkish population, with this increase being more pronounced in males. The mean mesiodistal and buccolingual diameters of permanent teeth can be useful for orthodontists, prosthodontists, anatomists, anthropologists, and forensic dentistry specialists.

Aim: To present the treatment and long-term post-treatment results of an adult case presenting with an Angle Class II anterior openbite malocclusion that involved the use of zygomatic anchorage for the intrusion of the maxillary posterior teeth. Methods: A 23-year-old female patient with a bilateral Angle Class II molar and canine relationship, a 4 mm overjet and a 6 mm anterior open-bite was treated using zygomatic anchorage in order to correct the dental and skeletal relationships, and eliminate the anterior open-bite to achieve an ideal overjet, overbite and improved facial aesthetics. Orthodontic brackets were placed on the maxillary and mandibular teeth. Under local anaesthesia, a subperiosteal flap was raised, and two titanium miniplates were bilaterally placed in the zygomatic area. The molars were intruded by applying 400 grams of force to the miniplates via connection to the upper arch wire. Results: By intruding the molar teeth using zygomatic anchorage, the anterior open-bite was corrected to achieve an Angle Class I occlusion, an ideal overbite and a harmonious facial profile that were successfully maintained after a 10-year follow-up period.
