When compared to the French-Canadian sample of Demirjian, Brazilian males and females were 0.681 years and 0.616 years, respectively, more advanced in dental maturity. There was no significant correlation between dental maturity and body mass index.

The Atraumatic Restorative Treatment (ART) was originated with the intention of healing the need for dental treatment for poor communities. With the development of the technique there has been an expansion of its use both in public health and in private practices. Through a review of the literature, the objective of this work is to integrate information about the history, evolution, advantages and disadvantages, as well as to increase the knowledge of dentists so that they can perform with more confidence. ART is based on the philosophy of minimal intervention, its use is plausible in several situations, both in public and private services, since the technique preserves healthy tissues and reduces more invasive procedures such as endodontics and exodontia. There is a need for professionals to increase their knowledge of the technique.

The difficulty in pediatric dentistry care, caused by non-collaborative child behavior, may be associated with the stress and anxiety of the parents, who often have gone through negative experiences during dental care. This study aims to show the influence that parents have on their children during pediatric dentistry treatment. A literature review was carried out on the influence of the tutor during dental care and, based on the information collected and on the experience of experts in the area, a booklet was developed with orientations to parents of pediatric dentistry patients. There is considerable influence of parents and guardians in the behavior of children during dental care and those who receive prior treatment orientation are able to obtain better collaboration, improving the professional's performance.

A case of giant cell granuloma in a 7-year-old boy was reported. The lesion was probably caused by trauma and was interfering with the normal eruption of the permanent maxillary left lateral incisor. Differential diagnosis and treatment of this lesion are discussed.

O objetivo deste estudo foi observar, ao microscópio eletrônico de varredura (MEV), a micromorfologia do esmalte de dentes decíduos intacto ou desgastado após condicionamento com ácido fosfórico a 37% ou com sistemas adesivos autocondicionantes de uma ou duas etapas. Foram selecionados 15 dentes decíduos, que foram divididos em três grupos, com 5 dentes em cada, de acordo com o agente condicionador e dentre eles, sub-divididos mantendo-se a superfície do esmalte intacta ou desgastada. G1: ácido fosfórico a 37% (Condicionador Dental Gel - Dentsply). G1A: esmalte intacto. G1B: esmalte desgastado. G2: condicionamento com primer do sistema adesivo autocondicionante de duas etapas (Adhese - Ivoclar Vivadent). G2A: esmalte intacto. G2B: esmalte desgastado. G3: condicionamento com sistema adesivo autocondicionante de etapa única (Xeno III – Dentsply). G3A: esmalte intacto. G3B: esmalte desgastado. Após os tratamentos propostos, todas as amostras foram desidratadas, montadas em bases metálicas e observadas ao MEV quanto ao padrão de condicionamento ácido. As amostras do G1A revelaram um padrão não homogêneo de condicionamento (áreas de esmalte condicionado e outras não condicionadas). No G1B foi observado um padrão homogêneo de condicionamento, prevalecendo o padrão Tipo 2 de Silverstone et al. (1975). As amostras dos G2A e G2B não revelaram um padrão homogêneo de condicionamento, tanto no esmalte íntegro como no desgastado. Concluiu-se que o uso do ácido fosfórico parece ser mais favorável para a formação de uma superfície micro retentiva, notadamente no esmalte desgastado. O uso de sistemas adesivos autocondicionantes, tanto no esmalte intacto como no desgastado não propiciou a formação de uma superfície do esmalte micro retentiva
