Virtual reality in Pediatric Dentistry has enormous potential, in the treatment of phobia of dental treatments, this technology is also promising, since it shows satisfactory results and in the surgical area it has a high potential for complex treatments, allowing predictable and safe results. However, future studies should have to establish technological standards with high data quality and in the development of applications approved for clinical routine. Distraction is a non-pharmacological pain management technique commonly used by Pediatric Dentists to control pain and anxiety. There are some new techniques that use audio and video stimulation and distract the patient by exposing him to three-dimensional videos. These techniques are called virtual reality audiovisual systems. The objective of this case was to evaluate the effectiveness of virtual reality glasses as a distraction aid to reduce anxiety in a 7-year-old girl who attends the pediatric dentistry office to perform a dental extraction procedure., Competing Interests: Conflicto de intereses: Los autores declaran que no existe conflicto de intereses

Mucopolysaccharidosis type VI, also known as Maroteaux-Lamy syndrome, is an autosomal recessive lysosomal disorder, due to the deficiency of the enzyme arylsulfatase B that leads to the accumulation of dermatan sulfate in the tissues and its urinary excretion. Mucopolysaccharide deposition leads to a progressive disorder affecting multiple organs that often results in death at a young age. This disease has several oral manifestations, among which dental complications can be serious and include follicles similar to dentigerous cysts, malocclusions, condylar defects and gingival hyperplasia, in addition to a short neck, corneal opacity, macroglossia, skull enlargement, anteroposterior dimension long, claw hand is some of the clinical features. A case of a 14-month-old patient is presented, who attended a pediatric dentistry consultation for episodes of fever, low weight, severe gingival hyperplasia. Physical examination revealed coarse facies, short neck, pectus excavatus, hands with decreased grip, and neurodevelopmental delay. On intraoral examination, dental eruption delayed, generalized gingival hyperplasia, palate with little transverse growth. On radiographic examination, dental organs included and poor position in the anterior sector, upper molars within the maxillary sinus, rotated lower canines. He is referred to medicine for biochemical tests and genetics for diagnosis. Detailed biochemistry MPS type VI, confirmed by molecular testing. The clinical manifestations in this case correspond to the clinical form of rapid progression reported in these patients. They report: short stature, skeletal malformations and alterations at the oral level. Children with severe MPS VI start early and progress rapidly, bone radiographs and urine GAG measurement are helpful for diagnosis with genetic and ARSB enzyme activity. It is necessary to strengthen the knowledge in dentistry and the general population about the clinical characteristics of type VI mucopolysaccharides in order to have an early diagnosis and management of pathologies in these patients., Competing Interests: Potenciales conflictos de interés: Los autores declaran que no existe conflicto de intereses
