Mesiodens are a type of supernumerary tooth that appears more frequently in the definitive dentition, they are pieces generally located in the midline of the upper jaw, of unknown etiology, but the most accepted theory is due to a hyperactivity of the dental lamina during morphogenesis. The purpose of this work is to describe the case of a 14-year-old male patient with no relevant pathological history. The intraoral clinical analysis shows a dental organ in the midline of the upper jaw compatible with a mesiodens and another included located at the level of the nasal cavity. On tomographic analysis there is presence of a hyperdense area between upper incisors with a characteristic compatible with a mesiodens, in a sagittal section a hyperdense area is observed 7mm from the alveolar rim towards the floor of the nostrils, an inverted dental structure with a diameter of 8mm, ectopic loc...

 Fluorine is a chemical element, it plays a very important role in the oral cavity, bone formation in the first years of life, and it is a fundamental part in the appearance of enamel crystals. It works in the demineralization and re-mineralization processes that occur in the oral cavity, these are found in different types of food that are consumed every day, their main source of consumption is drinking water, fluorinated supplements, formula milk, toothpaste, Oral gum should be consumed with measure in its application for a good dental brushing since excess fluoride can cause a pathology called dental fluorosis, which is why the supervision of adults is recommended at the time of oral hygiene in children. The objective of this literature review is to sensitize parents and health professionals about application protocols and their appropriate use of fluorine compounds, helping to preven...

 Cysts are pathological cavities with liquid, semi-liquid, solid or gaseous content, lined with epithelium on the inside and by connective tissue on the outside. The peri-apical cyst is a common inflammatory lesion of the jaws, which upon reaching a significant size, retention or even the displacement of adjacent teeth, is derived from the remains of Malassez. A case was presented of a patient who came to the dental office, asymptomatic with the presence of leaking restorations. The clinical examination revealed soft palatal tissue without bone support at the level of pieces # 11 and # 12; radiographically, a hypodense, well-defined radiolucent image was evidenced, including vestibular and palatal tables, total palatal bone lysis and mucosal involvement. The lesion was surgically treated with apicoectomy, bone regeneration, and fibrin-rich plasma. In the postoperative control, an adequa...
