ABSTRACT
Abstract The quality of the dentin root is the most important factor for restoration resin sealing and drives the outcome of endodontic treatment. Objective This study evaluated the effect of different filling pastes and cleaning agents on the root dentin of primary teeth using Fourier-transformed Raman spectroscopy (FT-Raman), micro energy-dispersive X-ray fluorescence (µ-EDXRF) and scanning electron microscopic (SEM) analysis. Material and Methods Eighty roots of primary teeth were endodontically prepared and distributed into 4 groups and filled according to the following filling pastes: Control-no filling (CP), Calen®+zinc oxide (CZ), Calcipex II® (CII), Vitapex® (V). After seven days, filling paste groups were distributed to 4 subgroups according to cleaning agents (n=5): Control-no cleaning (C), Ethanol (E), Tergenform® (T), 35% Phosphoric acid (PA). Then, the roots were sectioned and the dentin root sections were internally evaluated by FT-Raman, µ-EDXRF and SEM. Data was submitted to two-way ANOVA and Tukey tests (α=0.05). Results Regarding filling pastes, there was no significant difference in organic content. CP provided the lowest calcium values and, calcium/phosphoric ratio (Ca/P), and the highest phosphoric values. For cleaning agents there was no difference in organic content when compared to the C; however, T showed significantly higher calcium and Ca/P than PA. All groups showed similar results for phosphorus. The dentin smear layer was present after use of the cleaning agents, except PA. Conclusion The filling pastes changed the inorganic content, however they did not change the organic content. Cleaning agents did not alter the inorganic and organic content. PA cleaned and opened dentin tubules.

A perda precoce dos dentes decíduos pode ocorrer pela falta de diagnóstico e tratamento na fase inicial da cárie dentária. O objetivo foi relatar o tratamento reabilitador estético e funcional de uma criança de 4 anos e 5 meses de idade, do gênero feminino, com cárie precoce da infância severa. Durante a anamnese, além da queixa de dor nos dentes, notou-se apatia da criança e constrangimento da mesma ao falar e sorrir. Ao exame clínico inicial, a paciente apresentou ausência dos dentes 55, 54, 75, 84 e 85; lesões de cárie ativa do 73 ao 83; lesões cariosas ativas extensas (53, 52, 51, 61, 62, 63, 64, 65, 74) e presença de fístula na região dos dentes 51 e 52. Após o exame radiográfico, o tratamento proposto foi a realização da exodontia dos elementos dentários não passíveis de receber tratamento restaurador (53, 52, 51, 61, 62, 63, 64, 65, 74); restauração com resina composta do 73 ao 83; e posterior colocação de prótese total superior e prótese parcial inferior. Orientações sobre higiene bucal e dieta não-cariogênica foram realizadas em todas as etapas do tratamento para incentivar a criança e familiares à prática de hábitos saudáveis. Diante do tratamento realizado, concluiu-se que a reabilitação estética-funcional recuperou as funções estéticas, fonéticas e mastigatórias da paciente; colaborando para a melhora da autoestima da criança o que gerou satisfação dos familiares. O trabalho educativo em estimular a criança e os cuidadores foi essencial para o sucesso do tratamento e manutenção da saúde bucal...
Dental caries is a disease related with sucrose rich diet and poor oral hygiene. During childhood, if caries disease is misdiagnosed, it can lead to early loss of primary teeth. This study aimed to report the aesthetic and functional rehabilitation treatment in a female child aged 4 years and 5 months, with severe early childhood caries. In the case history, as well as complaints of toothache, the child showed apathy and embarrassment to talk and smile. In initial clinical examination, it was noticed lack of teeth 55, 54, 85, 84 and 75; active caries lesion on teeth 71, 73, 81, 82 and 83; the dental elements 51, 52, 53, 61, 62, 63, 64, 65 and 74 presented with extensive coronary destruction bellow the gingival margins, and the teeth 51 and 52 with the presence of fistula. After radiographic evaluation, the treatment proposed was comprised by destroyed teeth extraction, resin composite restoration of all cavities and subsequent placement of upper denture and lower partial denture. Oral hygiene and non-cariogenic diet orientations were accomplished since the initial treatment to encourage the child and her family to practice healthy habits. After accomplished the treatment, it could be concluded that aesthetic and functional rehabilitation recovered the patient aesthetic, phonetic and mastication functions. This fact contributed to improve the childs self-esteem and it promoted satisfaction of her family. The dentist educational work and the stimulus of child and her caregivers were essential for treatment successful and for patient oral health maintenance...
