RESUMEN
Few reports have been published to date on the management of bone fenestration in the anterior maxilla using leukocyte-platelet-rich fibrin (L-PRF) with deproteinized bovine bone mineral allograft (DBBMA). This case report demonstrates the use of L-PRF associated with DBBMA to repair a bone fenestration after the placement of 2 implants in the anterior maxilla. Placement of 2 osseointegrated implants was planned to replace the missing maxillary central incisors of a patient with bone loss in the buccal region. Reverse treatment planning predicted the fenestration of the buccal cortical plate and exposure of the implants. The implants were placed, and fenestration of the buccal cortical bone around the body of the implants occurred as expected. A mixture of L-PRF and DBBMA, mediated by injectable platelet-rich fibrin (a combination sometimes referred to as sticky bone), was positioned to cover the defect. Cone beam computed tomography 6 months after the intervention showed complete coverage of the fenestration with newly formed bone tissue. The use of L-PRF associated with DBBMA efficiently covered the fenestration and promoted new bone formation.

Aim: This study assessed whether the presence of malocclusion had a negative impact on the oral health-related quality of life (OHRQoL) of eight to ten-year-old children of low socioeconomic status. Methods: A cross-sectional study was conducted with a total of 111 children, eight to ten years of age, randomly selected from public schools from Diamantina, MG, Brazil. The number of children was determined by a sample size calculation. Two calibrated examiners performed clinical oral examinations for the diagnosis of malocclusion, dental caries experience, and traumatic dental injuries following the Dental Aesthetic Index (DAI), the World Health Organization (WHO), and Andreasen's classification, respectively. The Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) was applied to evaluate the OHRQoL. Descriptive and bivariate (p < 0.05) analyses were also performed. Results: Children had a mean age of 8.89 ± 0.82 years, of which 52.3% were female. The prevalence of malocclusion was 62.2%. Significant differences were found in emotional (p = 0.045) and social (p = 0.017) well-being subscale scores as well as in the total CPQ8-10 (p = 0.022) scores between children with and without malocclusion. Conclusion: The presence of malocclusion negatively impacted the OHRQoL of children aged eight to ten years of age of a low socioeconomic status.
Objetivo: Este estudo avaliou se a presença de maloclusão impactou negativamente a qualidade de vida relacionada à saúde bucal (QVRSB) de crianças de oito a dez anos de idade de baixo nível socioeconômico.Métodos: Um estudo transversal foi conduzido com um total de 111 crianças de oito a dez anos de idade selecionadas aleatoriamente em escolas públicas de Diamantina, Brasil. O número de crianças foi determinado por cálculo amostral. Dois examinadores calibrados realizaram exames clínicos bucais para o diagnóstico de maloclusão, experiência de cárie dentária e lesões dentárias traumáticas após o Índice de Estética Dental (DAI), OrganizaçaÌo Mundial da Saúde (OMS) e classificaçaÌo de Andreasen, respectivamente. A versão brasileira do Child Perceptions Questionnaire (CPQ8-10) foi aplicada para avaliar a QVRSB. Foram realizadas análises descritivas e bivariadas (p < 0,05). Resultados: As crianças tinham média de idade de 8,89 ± 0,82 anos, sendo 52,3% do sexo feminino. A prevalência de maloclusaÌo foi de 62,2%. Foram encontradas diferenças significativas nos escores das subescalas de bem-estar emocional (p = 0,045) e social (p = 0,017), como também nos escores totais do CPQ8-10 (p = 0,022) entre crianças com e sem maloclusaÌo. Conclusão: A presença de maloclusão impactou negativamente a QVRSB de crianças de oito a dez anos de idade de baixo nível socioeconômico.
