Aim: This study aimed to assess the interest of dental students, clinicians and professors in a mobile app for calculating dosages of medicines for use in Pediatric Dentistry. Methods: The cross-sectional survey involved a random sample of undergraduate and postgraduate pediatric dental students, clinical pediatric dentists and professors. Initially, participants watched a video about an early version of the app. They then answered a questionnaire about their clinical experience, calculation routine, and interest in the app. Descriptive analyses were carried out. Results: Of the 41 participants (20 students, 10 clinicians and 11 professors), 87.8% recognized the need to adjust doses of medicines used in pediatric dentistry, but only 56.1% felt confident in doing so. Almost a fifth of participants (19.5%) admitted errors in prescribing medicines for pediatric dental patients. After seeing the app's functionalities, 92.7% considered it relevant, and 87.8% were interested in the full version. Conclusion: The app is deemed relevant, necessary, and of significant interest to the target audience, indicating potential for investment and full development.

Métodos: A pesquisa transversal envolveu uma amostra aleatória de estudantes de odontologia pediátrica de graduação e pós-graduação, odontopediatras clínicos e professores. Inicialmente, os participantes assistiram a um vídeo sobre uma versão inicial do aplicativo. Em seguida, eles responderam a um questionário sobre sua experiência clínica, rotina de cálculos e interesse no aplicativo. Análises descritivas foram realizadas. Resultados:Dos 41 participantes (20 estudantes, 10 clínicos e 11 professores), 87,8% reconheceram a necessidade de ajustar as doses de medicamentos usados em Odontopediatria, mas apenas 56,1% se sentiam confiantes para fazê-lo. Quase um quinto dos participantes (19,5%) admitiu erros na prescrição de medicamentos para pacientes odontopediátricos. Após verem as funcionalidades do aplicativo, 92,7% o consideraram relevante, e 87,8% demonstraram interesse na versão completa.

Malocclusion Impact Scale for Early Childhood (MIS-EC): development and validation

Abstract: This study aimed to develop and validate the Malocclusion Impact Scale for Early Childhood (MIS-EC), a malocclusion-specific measure of oral health-related quality of life (OHRQoL) of children aged 3-5 years and their parents/caregivers. A pool of items was analysed to identify those relevant to the assessment of the impact of malocclusion on OHRQoL. Dental professionals and mothers of children with and without malocclusion rated the importance of these items. The final version of the MIS-EC was evaluated in a cross-sectional study comprising 381 parents of children aged 3-5 years to assess construct validity, internal consistency and test-retest reliability. Twenty-two items were identified from item pooling. After item reduction, eight items were chosen to constitute the MIS-EC, in addition to two general questions. The MIS-EC demonstrated good internal consistency (Cronbach's alpha = 0.79 for the Child Impact section and 0.53 for the Family Impact section), and excellent test-retest reliability (ICC = 0.94), floor effect was 55.7% and ceiling effect 0%. MIS-EC scores indicating worse OHRQoL were significantly associated with the presence of malocclusion (p < 0.05). The MIS-EC is reliable and valid for assessing the impact of malocclusion on the OHRQoL of preschool children and their parents/caregivers.

Impaction of mandibular third molars after orthodontic treatment by the edgewise method: a retrospective study

Abstract This study aimed to determine the incidence of mandibular third molar (M3) impaction after orthodontic treatment by edgewise appliances, and identify possible determinant factors of M3 impaction. A retrospective cohort study was conducted with 1154 patients. Complete orthodontic records were analyzed pretreatment and posttreatment, considering the following variables: type of Angle malocclusion, treatment with or without extraction of first premolars, overbite, stage of dentition, M3 prior angulation and duration of orthodontic treatment. Impaction was determined after radiographic evidence of total closure of the root apex. The chi-square test and Poisson regression (p < 0.05) were used for statistical analysis with a hierarchical approach. Rate ratios (RR) and 95% confidence intervals (CI) were calculated. Mandibular M3 impaction incidence was 17%. Overbite equal to or greater than 4 mm (RR = 1.23, 95%CI: 1.11-1.26, p < 0.001), prior mesial angulation of M3 (RR = 0.59, 95%CI: 0.52-0.68, p < 0.001), non-extraction of first premolars (RR=1.06, 95%CI: 1.01-1.12, P=0.019) and orthodontic treatment time equal to or less than three years (RR = 0.94. 95%CI: 0.90-0.99, p < 0.014) were significantly associated with impacted M3. There was no correlation between the type of Angle malocclusion and the risk of impaction. In conclusion, the incidence of mandibular M3 impaction was considered low. The main pretreatment factors directly involved in impaction were mesioangulation of M3 and overbite equal to or greater than 4 mm. Orthodontic treatment with extraction of first premolars and treatment time greater than 3 years reduce the risk of impaction.
