Aim: Cephalometric analysis is a main part of diagnostics in orthodontics. Modern cephalometric analysis methods include using digital software or mobile applications. This study aimed to assess the validity and reliability of the CephNinjaPro application for linear and angular cephalometric measurements.
Methods: In this cross-sectional study, 30 randomly selected lateral cephalograms were digitized by a digital scanner. The required landmarks for five linear and eight angular measurements were identified on all cephalograms using a fine tip pen by an experienced orthodontist, and then rescanned. To assess the validity of manual versus digital landmark identification using the CephNinjaPro application, the landmarks were identified on scanned cephalograms in both the CephNinjaPro application and Dolphin software. The results were compared before and after landmark identification. The results of the Dolphin software and the CephNinjaPro application were also compared before and after landmark identification. Data were analyzed using the paired t-test and Wilcoxon test.
Results: The results showed significant differences in the angles SNA (P<0.001), SNB (P<0.001), inter-incisal (P=0.001), and MP-SN (P<0.001), and the Ga (P<0.001) between the Dolphin software and CephNinjaPro application before landmark identification. Also, significant differences were observed in the Ga (P<0.001) and SN-MP (P<0.001) angle between the Dolphin software and CephNinjaPro application after landmark identification.
Conclusion: The CephNinjaPro application has acceptable validity and reliability for most of the linear and angular cephalometric measurements from the clinical perspective. Nonetheless, interpretation of results regarding some measurements should be done with caution.

Aim: This study aimed to assess the feedback of patients regarding orthodontic treatment during the coronavirus pandemic of 2019 (COVID-19).Methods: In this observational study, keywords related to orthodontic treatment along with either “corona” or “COVID” were searched in Twitter during a two-month period from 2 October 2020 to 12 October 2021. The retrieved tweets were categorized into five themes of pain, getting braces, limitations due to COVID-19, seeking information, and delayed treatment based on content, and were then manually categorized into three groups of positive, neutral, and negative tweets. Next, a coding system was designed by the software MAXQDA, and the tweets were coded. Data were analyzed by the analysis feature of MAXQDA.Results: Of a total of 424 tweets retrieved, 95 were excluded. The majority of the tweets were about limitations due to COVID-19 (n=156) and were negative (n=213). Also, the majority of the tweets were posted by female users (67.5%). The most common reason for the negative tweets of patients was delayed treatment (43.9%). Also, poor performance of orthodontic clinics and orthodontists with regard to informing and reassuring the patients about protective measures was another reason for the negative tweets of patients (12.5%).Conclusion: Delayed treatment was the most common cause of patient dissatisfaction followed by poor awareness and reassurance of patients regarding adherence to the preventive measures and hygienic protocols during the COVID-19 pandemic.

Background: Following the morphological features of different races and ethnic groups, knowledge of standard dentofacial patterns of each ethnic group is essential. Therefore, this study aimed to explain cephalometric standards for the Zanjanian population according to Downs' analysis and compare them to Caucasian individuals.Methods: Seventy lateral cephalometries of Zanjanian adults (17 - 29 years old) who had been referred to a private orthodontic office in Zanjan, Iran with class I molar and canine relationship and normal overjet and overbite as well as minimum crowding/spacing/rotations were scanned and traced with the Novatech scanner and Dolphin software version 10. Next, statistical analyses were performed in order to compare the Zanjanian population to Caucasians. Results: We found a significant difference between males and females in terms of interincisal angle, incisor-occlusal angle, incisor-mandibular plane angle, upper incisor proclination, facial angle, and angle of convexity.Discussion: The analysis of six statistically significant parameters indicates that the upper and lower incisors in women of Zanjan were proclined and protruded compared with those of Caucasian subjects. Due to the statistical analysis on facial angle and angle of convexity, women also show more maxillary prognathism and skeletal class II pattern. Generally, a comparison of Zanjanian population cephalometrics based on Downs' analysis showed an increase in maxillary prognathism, maxillary and mandibular incisal protrusion and posterior rotation of the mandible.Conclusions: In conclusion, the Zanjanian population tends to have more dental and skeletal class II patterns than the Caucasians. In addition, gender comparison indicates lower and upper-incisors protrusion in women of Zanjan.
