This article describes a case of central giant cell granuloma in the right posterior region of the mandible in a 10-year-old boy. The lesion was removed by curettage and a histopathological examination was carried out.

The invaginated tooth, also called dens invaginatus or dens in dente, is a rare anomaly affecting human dentition, resulting from invagination of enamel organ into the dental papilla.Maxillary lateral incisors are the most commonly affected teeth. The accentuated pit within the DI accumulates debris causing prompt initiation and progression of dental caries with subsequent involvement of the pulp, resulting in periapical pathology. Invagination depth varies from a slight enlargement of the cingulum to an extended invagination into the apex. This anatomic variation means a true clinical challenge because of its complex anatomy. Early diagnosis is then essential to avoid any periodontal complications.This study aims to review: etiopathogenics, classification, elements of the diagnosis and provides guidelines for the management of dens invaginatus cases in clinic that provide hope for teeth that could not be saved before.

Introduction : Odontophobia is a complex anxiety disorder related to excessive fear of dental care. Of multifactorial origin, it affects more females than males at all ages. Odontophobia can also be associated with other disorders, namely post-traumatic stress disorder (PTSD), which is recognized in refugees from civil wars. Materials and methods : Descriptive and analytical cross-sectional epidemiological study, carried out during February 2020 at the Syrian refugee camp in Zaatari, Jordan, involving 200 consultants at the dental office to assess their degree of odontophobia and to determine the risk factors associated with this disorder, particularly post-traumatic stress disorder (PTSD). Results : The authors collated 200 subjects of which 125 (62.5%) were phobic with a corah score (> or = to 13) and 75 (37.5%) were non-phobic with a corah score (< to 13). The sex ratio was statistically different between the two populations with a predominance of female sex (p=0.025). odontophobia is also related to the length of time spent in Syria during the civil war, it is observed more in 96 (48%) patients who spent between (13 and 24 months) (p=0.017). Similarly, odontophobia is influenced by post-traumatic stress disorder in its severe form (p=0.011). Conclusion: Descriptive and analytical observational epidemiological study showing the high prevalence of odontophobia among Syrian refugees consulting at the dental office of the Moroccan military medical-surgical hospital in Zaatari camp in Jordan and its influence by post-traumatic stress disorder (PTSD).

L'action carioprotectrice du fluor par voie topique est reconnue depuis plus d’une cinquantaine d’année. Ce dernier est devenu aujourd’hui, l'un des piliers de la prévention de la maladie carieuse. Toutefois, l’ingestion excessive de cet oligo-élément durant les premières années de la formation des dents peut entrainer l’apparition d’une fluorose dentaire. Il s’agit d’une anomalie de structure acquise pré-éruptive caractérisée par un aspect polymorphe variant en fonction de la sévérité d’atteinte. Elle peut engendrer, dans certains cas, en fonction de son impact sur la couleur et l'aspect de surface de l'émail dentaire, un préjudice esthétique et fonctionnel majeur. Pour pallier cette problématique, la dentisterie moderne propose un vaste champ thérapeutique allant de l’éclaircissement aux restaurations prothétiques. L’objectif principal est d’adopter une thérapeutique adaptée selon chaque situation tout en étant le moins invasif possible. C’est dans cette optique que ce travail se propose de présenter la gestion thérapeutique d’une fluorose dentaire chez une patiente âgée de 14 ans. Le traitement a consisté en la combinaison de deux méthodes :  la micro-abrasion et l’éclaircissement externe ambulatoire ce qui a permis d’obtenir un résultat très satisfaisant pour la patiente, tout en respectant le principe d’économie tissulaire.
