Young patients can also be affected. TROS type 1 (TROS1 ) is most often found in young, non-obese children with no associated comorbidities, presenting with an otorhinolaryngological (ENT) obstacle, generally an enlargement of lymphoid tissue (tonsils and/or adenoids).Objective: The aim of this article was to outline the consensus.Materiel and methods: A collaborative work, realized on the request of the French Society of Sleep Research and Medicine, to provide recommendations for the management of obstructive sleep apnea syndrome type 1 (OSA1 ) in children was published in 2023. This work brought together various experts in pediatric sleep disorders breathings (SDB). A sleep study for OSA1 is not mandatory when at least two nighttime symptoms are noted. A specialist otolaryngologist examination, including nasofibroscopy, is essential during diagnosis.Discussion: The ENT specialist is the mainstay of initial care, but works as part of a multidisciplinary team that includes pediatricians, general practitioners, orthodontists and linguo-oro-maxillo-facial rehabilitation specialists.Conclusion: Whatever the treatment, follow-up must be continuous and multidisciplinary; it is essential to ensure the effectiveness of the treatments implemented, the absence of SDB recurrence and the recovery of nasal breathing.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 3","pages":"249-260"},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142670211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Light, continuous forces are required to achieve optimal tooth movement. Nickel-titanium (Ni-Ti) archwires are commonly used as initial archwires due to their unique properties.Objective: The objective of this study was to compare the Copper Ni-Ti 35°C and the conventional Ni-Ti in dental alignment and maintaining the mandibular arch form.Material and methods: A double-blind randomized controlled trial was conducted on adult patients, recruited from the orthodontic department of Saint Joseph University of Beirut and a private orthodontic practice in Beirut. They were randomly allocated into two groups: Copper Ni-Ti 35°C group and conventional Ni-Ti group, where they received both 0.016 inch and 0.018 inch archwires. Out of three available arch forms, each patient received the most suited archwire to their mandibular arch. Digital impressions were taken every three weeks and analyzed on Orthoanalyzer™. The Little Irregurality Index, space analysis and intercanine, interpremolar, intermolar distances were measured. Repeated measures analysis of variance ANOVA was used followed by Bonferroni multiple comparisons tests.Results: Forty patients were randomized in a 1:1 ratio to either Copper Ni-Ti 35°C or Ni-Ti group. No significant difference between the Copper Ni-Ti 35°C and the conventional Ni-Ti was noted in the resolution of dental crowding (p > 0.05). No significant difference in the dimensions of the mandibular arch was found within and between the two groups (p > 0.05).Conclusion: Copper Ni-Ti 35°C doesn't differ from the conventional Ni-Ti regarding the alignment rate and maintaining the mandibular arch form.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 3","pages":"237-247"},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142670212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is currently accepted that one child in two suffers an alveolar-dental trauma before leaving school, with a peak incidence between the ages of 8 and 12, all types of trauma combined. The maxillary central incisors are most affected (79.6%), with mainly \"simple\" or \"complex\" coronal fractures when the pulp is involved. The main objective in managing these complex fractures is to preserve pulpal vitality within an acceptable timeframe.Material and method: The author presents three pulp vitality preservation therapies involving tissue preservation and regeneration techniques using bioactive materials applied directly to the pulp. Materials and clinical protocols are described.Conclusion: Knowledge of pulp biology and healing processes has led to the development of vitality-preserving therapeutic strategies that have become essential in the management of traumatized teeth in children and adolescents. The regenerative potential of immature tooth pulp is considerable, enabling dentine repair through the use of bioactive materials. These therapies require a rigorous surgical approach that determines prognosis, and precise monitoring to ensure that any complications are intercepted.","PeriodicalId":101415,"journal":{"name":"L' Orthodontie francaise","volume":"95 4","pages":"299-303"},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141750166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives were to evaluate low socioeconomic status of patients as a factor associated with increased treatment need and the correlation between socioeconomic status and dysmorphosis on one hand, and cooperation level on the other.Material and methods: This was a retrospective comparative monocentric observational cohort study. Included subjects were under 16 years old at the time of orthodontic braces placement and were beneficiaries of the complémentaire santé solidaire (C2S) or not (non-C2S). Evaluated criteria included treatment need (IOTN-DHC), antero-posterior and vertical dysmorphosis (FMA, ANB, IMPA, I/F), and compliance. Fisher and Wilcoxon tests were performed. A 5% threshold was retained.Results: Overall, 173 patients were included and divided into two groups: C2S/non-C2S. Neither treatment need nor skeletal and alveolar-dental dysmorphosis are correlated with socioeconomic status. Cooperation is correlated with low socioeconomic status across all evaluated criteria: three times more bracket debondings, three times more remarks about failure to wear elastics, 1.25 times more missed appointments, ten times more treatment abandonments.Conclusion: It may not be dysmorphosis that makes orthodontic treatment of low socioeconomic status patients more difficult, but rather a lack of cooperation. This calls for clinical and policy interventions to increase patient involvement in treatment.

D and B slow maxillary advance, stimulate mandibular advance and correct the skeletal Class II. They normalize the molar class by distalizing the maxillary arch (palato-position of the maxillary incisors, retreat of the maxillary first molar) and by mesializing the mandibular arch (vestibulo-position and vestibulo-version of the mandibular incisors by 5 to 6°, advance of the mandibular first molar).
