Generalization and the lack of knowledge about this stage of life can lead to false assessments that tend to oscillate between positive and negative. Objective: a) To characterize the beliefs about aging of Dentistry undergraduates from a private higher education institution; b) to verify if the belief of the undergraduates had about aging may interfere in the choice of future dental care given to older people, and; c) to assess the profile of the respondents by gender, age and graduation period. Material and methods: This cross-sectional descriptive study was conducted with students properly enrolled in the Dentistry course of a private institution, in 2016 (N = 90). The profile of the population was defined by gender, age and graduation period. It was verified the preference and predilection in future working or not working with a certain age group. Also, the beliefs about aging were investigated through a semantic scale. Distributions of absolute and relative frequencies were made. Statistical analysis was given by using SPSS version 20.0. Results: Most respondents were female (78.9%); with a mean age of 23.34 years; enrolled in the 8th period; 51.1% said they had no preference in future work with particular age range; and, there was a predominance of positive view, with tendencies towards neutrality. There were no statistically significant differences between the beliefs toward aging and the variables: gender, age and period. Statistically significant dependencies were found between the beliefs about old age and preference in working or not working in future treat a certain age range of the population. Conclusion: The respondents have a more positive view of old age; no predilection to provide dental care to a certain age group, highlighting a general and humanist profile in relation to chronological age. <![CDATA[<b>Dentofacial deformity and quality of life: a case control study</b>]]> Introduction: Dentofacial deformity (DFD) may be defined as facial and dental disproportions great enough to affect significantly the individual's quality of life (QoL). Objective: This study aimed to verify and compare the impacts of and differences in QoL in individuals with and without DFD. Material and methods: The impact of DFD on QoL was evaluated through the following questionnaires: Short Form Health Survey (SF36), a generic Oral Health Related Quality of Life (OHRQoL) questionnaire (Oral Health Impact Profile Questionnaire - OHIP-49), a condition-specific questionnaire for DFD (Orthognathic Quality of Life Questionnaire - OQLQ) and a single question answered by Visual Analogue Scale (VAS). Results: Greater and negative impacts on QoL were observed in patients with DFD in all domains of OQLQ and OHIP; and in two domains of SF36: emotional well-being and social functioning. Conclusion: DFD greatly and negatively impacted on QoL of individuals with DFD greater mainly evidenced through general and specific OHRQoL questionnaires. <![CDATA[<b>Knowledge of dentists on child abuse in two Brazilian southern cities</b>]]> Introduction: The child abuse against children and teenagers is relevant and the dentist has a fundamental role in the process of identification of suspected cases. Objective: To evaluate the level of knowledge of the dentists about child/teenager abuse and the attitude towards identified cases, in the cities of Rio Negro (ParanĂ¡, Brazil) and Mafra (Santa Catarina, Brazil). Material and methods: Questionnaires were applied to 44 professionals of these cities, who practiced in private and/or public health service. The questions covered the profile of respondents regarding gender, institution (public or private), level of education, practicing time and place. The information on abuse comprised the level of information about violence and knowledge on the compulsory notification of suspected cases. Results: Regarding the cases of abuse, 34% of the sample dealt with this situation. Almost half of respondents (47.7%) reported being able to recognize the typical lesions of child abuse, yet only 32% felt trained to do so. Only 22.7% reported having training to detect suspected cases. And 91% said they would notice the Guardian Council. About 48% confirmed they had knowledge of the legal implications in case of omission. Conclusion: Most of the dentists had insufficient knowledge about child abuse. However, the dentists know how to deal with such a situation. Continuing education seems to be an appropriate strategy to promote professional knowledge on the subject. It is also suggested the implementation of a national protocol to facilitate notifications and the classification of abuse types. <![CDATA[<b>Central giant cell granuloma (CGCG) in childhood: surgical treatment by maintaining the tooth germs</b>]]> Introduction: Central Giant Cell Granuloma (CGCG) is a nonneoplastic benign process, of unknown etiology, more common in children and young adults. When aggressive, the lesion may result in considerable bone destruction and deformation. Oral and Maxillofacial surgery strongly depends on the nature of injury and it may vary from more conservative to more aggressive approach. Case report: The aim of the present study is to report and analyze, a giant cell central lesion in a 7-year-old patient on the right side of mandible body treated by surgical enucleation, curettage, and maintenance of the tooth germs. Discussion: In less aggressive lesions, curettage followed by radiographic monitoring is the most widely suggested treatment choice. However, the "gold standard" for aggressive and deforming lesions would be en-bloc resection with a safety margin. Most revisions show recurrence rates of 15 to 20%, thus clinical monitoring is necessary at least one year after the intervention. Conclusion: After 12 months, panoramic radiograph and computed tomography indicated new bone formation and no recurrence. In addition, good healing of soft tissues and correct eruption of the teeth #42, #43 and #44 were observed. <![CDATA[<b>Oral rehabilitation with removable dental prosthesis in a six-year-old patient with hypohidrotic ectodermal dysplasia</b>]]> Introduction: Ectodermal dysplasia is an abnormality of the ectoderm and its derivatives, phenotypically expressed in males and genetically inherited from mothers. Objective: To report the efficacy of the prosthetics treatment of severe ectodermal dysplasia in a 6-year-old boy with hypohidrotic ectodermal dysplasia (HED). Case report: The boy had difficulty in speaking and eating and the condition also affected his self-esteem. Prosthetic treatments included the construction of acrylic custom trays, determination of the vertical dimension of occlusion (VDO), construction of upper and lower dentures, and palatal expansion procedure. Conclusion: Significant improvements in the patient's stomatognathic function and self-esteem were evident. <![CDATA[<b>Periodontal plastic surgery for treatment of gummy smile with cosmetic restauration treatment</b>]]> Introduction: Today, the appreciation of aesthetic dentistry by society brought to the search for materials and techniques that improve the appearance of smile, which is essential in maintaining physical and mental health of the patient.
