Introduction:The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is a multi-item psychometric instrument used to assess patients' perspective of the impact specifically related to Orthodontics. The cross-culturally adapted Brazilian version of the PIDAQ has demonstrated good reliability, validity and acceptability.Objective: The aim of the present study was to test the validity and reliability of the Brazilian version of the PIDAQ for use among adolescents aged between 11 and 14 years old.Methods: Having established the possibility of maintaining the operational characteristics of the Brazilian version of PIDAQ for the target age group, 194 individuals in the city of Belo Horizonte, Brazil, completed the questionnaire. The subjects were examined for the presence/absence of malocclusion based on the criteria of the Dental Aesthetic Index (DAI) to test discriminant validity. Internal consistency was measured by means of Cronbach's alpha coefficient which ranged from 0.59 to 0.86 for the subscales. Test-retest reliability was assessed by means of intraclass correlation coefficient which ranged from 0.54 to 0.89 for aesthetic concern and psychological impact.Results: Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores in comparison to those with malocclusion.Conclusion: These findings suggest that the Brazilian version of PIDAQ for adolescents has satisfactory psychometric properties and is applicable to this age group in Brazil.

Orofacial injuries resulting from Coronavirus-19 (COVID-19) are reported in the current literature. The etiology of these manifestations is still unknown, but them seem to have an association between the prone position and patient’s immunosuppression. Clinical features range from nonspecific ulcers to vesicles that may mimic viral infections. The search for a clinical protocol for the cure of these lesions is necessary. Thus, some studies about photobiomodulation, a low-level light therapy with regenerative tissue action, associated with antimicrobial photodynamic therapy, as a promising adjuvant treatment. Therefore, the present study aims to report a series of cases where photobiomodulation and photodynamic therapy were used in patients positive for COVID-19 and presented orofacial lesions during the time of hospitalization in the intensive care unit. In all cases, tissue regeneration was complete, demonstrating the effectiveness of photobiomodulation and photodynamic therapy as adjuvant therapy associated with the use of medicines.

The objective of this study was to present a clinical case of a pediatric patient with ASD who had experienced dental trauma and underwent dental treatment in a hospital environment under general anesthesia. A 10-year-old male patient who was Brazilian and had leukoderma was diagnosed with ASD at three years of age, he experienced trauma to the upper teeth, with avulsion of tooth 12 and extrusive displacement of tooth 11, after being run over by a car in February 2017. He was immediately taken to the emergency room, where he was seen by a dentist and he was immediately transferred to Hospital. In the out-patient clinic of this hospital, with the aid of protective stabilization and infiltrative anesthesia, tooth 12 was reimplanted 40 minutes after trauma and restrained with composite resin. He continued treatment in another city and Endodontic and paraendodontic treatment of teeth 11 and 12 was performed under general anesthesia. Follow-ups with the patient are continuing, with the last control periapical radiograph taken in January 2020. In this case, the proposed dental treatment was successful and did not lead to any complications.
