Background: Cephalometric analysis is essential in orthodontic diagnosis and treatment planning. With the increasing use of artificial intelligence (AI) in clinical practice, automated platforms such as WebCeph have been introduced; however, their accuracy and reliability across different types of measurements remain a concerns. Objectives: evaluate the agreement and reliability between skeletal and dentoalveolar cephalometric measurements obtained using an AI-based platform (WebCeph) and digital manual tracing performed with AutoCAD.Materials and Methods: A total of 100 lateral cephalograms were analyzed using WebCeph (AI-driven software) and digital manual tracing in AutoCAD. Fourteen Steiner and Tweed variables were selected and categorized into skeletal and dentoalveolar measurements. Statistical comparisons were performed using paired t-tests or Wilcoxon signed-rank tests, depending on data distribution. Agreement between the two methods was assessed using intraclass correlation coefficients (ICC) and Bland–Altman analysis. Conclusion: Overall agreement between WebCeph and AutoCAD was good for most variables (ICC ≥ 0.75). Skeletal and dentoalveolar measurements showed comparable reliability, although skeletal measurements demonstrated slightly smaller mean differences and narrower limits of agreement. Greater variability was observed in dentoalveolar variables, particularly those related to mandibular incisor inclination. Conclusion:WebCeph provides clinically reliable cephalometric measurements and can be considered a supportive diagnostic tool. However, selective manual verification is essential.

Introduction: Friedreich′s ataxia is an inherited disease affecting the nervous system and presents huge orthodontic challenges affecting the patient′s coordination and muscular function. Observation: Based on the rarity of this condition, the aim of this case report is to describe an unusual orthodontic treatment employed to manage a severe open bite in a 14‐year‐old male patient suffering from Friedreich′s ataxia, by highlighting the clinical decisions and treatment outcomes. Conclusion: Managing a severe anterior open bite in patients suffering from Friedreich′s ataxia by skeletal anchorage mechanics for posterior teeth intrusion is advantageous considering their health condition.

Pycnodysostosis refers to an uncommon autosomal recessive developmental anomaly, which results in decreased bone remodeling, manifesting itself in a variety of clinical and radiographic displays. We report two cases involving two sisters aged 12.5 and 8 years old from a consanguineous marriage. Both presented with distinctive manifestations of the syndrome and were observed at the Dental Consultation and Treatment Center of Ibn Sina Hospital in Rabat. They presented pathognomonic features of the disorder, including short stature, beaked nose, brachydactyly, obtuse mandibular gonial angle and acro‐osteolysis of the distal phalanges. This case report is aimed at highlighting these features, in particular the craniofacial and dental characteristics that help in diagnosing this genetic disorder and to emphasize the role of the dentist in this process.

INTRODUCTION: Les points A et B sont des repères squelettiques utilisés dans les études céphalométriques afin d´évaluer les rapports sagittaux entre le maxillaire et la mandibule, respectivement. L´objectif de ce travail est d´évaluer la fiabilité des points A et B comme repères squelettiques en étudiant l´influence du repositionnement incisif sur leur position céphalométrique. METHODES: La superposition des tracés céphalométriques de début et de fin de traitement de 30 patients hors croissance, présentant une biproalvéolie, et ayant bénéficié d´un traitement orthodontique avec extraction des quatre premières prémolaires a été réalisée pour évaluer le changement de la position des points A et B. Le seuil de significativité a été fixé à 0,05. RESULTATS: Dans notre étude, nous avons trouvé que le traitement orthodontique n´influence pas de manière statistiquement significative la position du point A. tandis que le point B est influencé de manière statistiquement significative par la quantité du repositionnement incisif (p= 0,01). En effet, pour chaque 1 mm de repositionnement incisif, le point B recule de 0,17mm. CONCLUSION: Le repositionnement incisif à l´arcade mandibulaire a induit un changement dans la position du point B vers l´arrière. Mots clés : inclinaison de l´incisive, repositionnement incisive, le point A, point B, céphalométrie.

Background: Third molar influence on anterior crowding is controversial, However, it is assumed that they play a major role in compromising dental arch space. Aim: To review the literature to clarify the role of third molars in anterior crowding and relapse after orthodontic treatment by means of a systematic review. Material and methods: A systematic search was conducted based on an electronic search of several databases (Pub Med, ScienceDirect, Cochrane Library) covering publications from 2010 to January 2022. The search was performed using the acronym PICOS, limited to the following keywords in English and French: «wisdom tooth» OR« third molar »AND «anterior teeth crowding». Results: On the basis of the keywords, 549 bibliographical references were initially identified. After the elimination of duplicate references and studies, the number of articles was reduced to 315. A review of titles and abstracts resulted in the selection of 23 articles. After reading the full text, 6 articles were included in this systematic review. Conclusion: No relationship between the incisors crowding and the presence of third molars was identified. Therefore, the indication for prophylactic removal of third molars to avoid incisor crowding is not justified.

Background: Obstructive Sleep Apnea (OSA) is considered to be a real public health problem, often unrecognized or underdiagnosed, requiring multidisciplinary care including orthodontics that plays an essential role in the screening and the management of ventilation. Objective: The aim of our study is to explain the important place of orthodontic therapies, whether orthopedic or surgical, in the multidisciplinary management of OSA and in the improvement of nasal breathing through a systematic review. Material and methods: A search of the literature was performed in the following databases: PubMed, ScienceDirect, Cochrane Library . The search was limited to publications written in English and French from 2010 to January 2022. Results: On the basis of the keywords, eighty-three references were initially identified. After the elimination of duplicates, the number of articles was reduced to seventy-nine. The study of the titles and abstracts made it possible to select fifty articles. After reading the full text, sixteen publications were included in this systematic review. Eight studies have investigated rapid maxillary expansion (RME), five studies have evaluated the effect of mandibular advancement (MA) and three studies have investigated the effect of genioplasty in children with OSA. Conclusion: Orthodontic arsenal, whether orthopedic, orthodontic, or surgical correction of jaws, is well suited and extremely beneficial for OSA treatment.

The dental biprotrusion characteristic of certain ethnic groups raises the question of treatment or of abstaining. In many situations this is accompanied by open bite in relation to the lingual volume or lingual support during pronunciation, the therapeutic solution must be considered and individualized. This article describes the orthodontic treatment of an anterior open bite of functional origin in a 23-year-old adult patient embarrassed by the cosmetic defect.
