Dentistry for babies aims to contribute to the formation of a generation with fewer dental problems, higher quality of oral health and more aware of the importance of prevention. The congenital gingival granular cell tumour (CGCT) is a rare benign soft tissue tumour in the newborn that can lead to respiratory difficulties and feeding. The aim of this work was to report two cases of CGCT in babies and discuss the clinical and histological differential diagnosis and their treatment, as well as the importance of knowledge of this pathology for dentists. Clinical features and treatment approaches are presented and discussed. The surgical approach improved the child quality of life and restored the parent’s confidence and emotional stability. Knowledge of this pathology helps in better diagnosis and treatment, which lead to a better quality of life of children and return confidence and emotional stability to parents.

Abstract The aim of the present transversal study was to evaluate the clinical and biochemical salivary parameters of children with and without erosive tooth wear (ETW). The study population was children aged 4 to 9 years. A trained and calibrated examiner (kappa value for intraexaminer reliability = 0.89) classified the children into ETW (n = 24) and control groups (n = 24), and applied the O’Brien index. The salivary flow rate was initially evaluated by stimulated sialometry (paraffin chewing). Afterwards, the collected saliva was submitted to biochemical analyses of pH, uric acid, total buffering capacity, ferric-reducing antioxidant power, reduced glutathione, calcium, and phosphorus. Among the ETW children, 20 (83%) had dental lesions restricted to enamel, and 4 (17%) presented lesions affecting both enamel and dentin. A statistically significant difference between the groups was obtained only for the pH values (t-test; p = 0.004), with averages of 7.31 and 7.56 for the control and the ETW groups, respectively. Considering the parameters evaluated in general, it is suggested that the salivary profile of children with ETW does not differ considerably from that of children without ETW. However, the pH mean value seems to be slightly higher in ETW children, but is still within the normal physiological range.

The purpose of the present study was to evaluate the erosive potential of different types (concentrated and powdered) and commercial brands of industrialised grape juices. The pH of all five fruit drinks was measured at two time points: immediately after preparation and 24 hours later. Sixty specimens of bovine enamel were randomly allocated and immersed in different types of grape juice (n = 10) for 10 minutes four times a day for fifteen days. The enamel alteration was analysed using surface Knoop microhardness (KHN) and surface roughness (Ra) tests at baseline and on the 5th, 10th and 15th days of the experiment. Two way ANOVA, Tukey's post hoc and Pearson's correlation tests were used for statistical analysis (α = 5%). The grape juices presented pH values ranging from 2.9 to 3.5. All of the tested juices promoted significant enamel mineral loss (p < 0.05) on the first evaluation (5th day of immersion) and produced a significant increase in the mean roughness from the 10th day on when compared to the control group (p < 0.05). By the 15th day, all of the beverages had produced surface roughnesses that were significantly higher than that of the control group. The results suggest that all grape juices, regardless of their commercial presentation, present erosive potential.

Odontopediatria é a especialidade que tem como objetivo o diagnóstico, a prevenção, o tratamento e o controle dos problemas de saúde bucal do bebê, da criança e do adolescente; a educação para a saúde bucal e a integração desses procedimentos com os dos outros profissionais da área da saúde. Na atualidade a Odontopediatria tem seu foco voltado para prevenção, tendendo a atender as crianças cada vez mais precocemente, além disso, procura-se durante o atendimento, promover tratamento compatível com as necessidades apresentadas. O objetivo deste artigo foi analisar a assistência odontológica prestada as crianças nos CEO, bem como a efetividade nesses atendimentos. A assistência odontológica infantil deve ocorrer na atenção básica e deve estar apta para atendimentos também nos CEO, dessa forma pode ocorrer assistência especializada através da atuação do odontopediatra, suprindo a demanda e cessando a dificuldade nos atendimentos. Concluiu-se que existe a necessidade do odontopediatra nos CEO, baseado na necessidade de mudar o perfil de cáries na faixa etária, principalmente de 5 anos, onde não houve melhorias nos últimos levantamentos, Projetos SB Brasil 2003 e 2010 e devido também não se ter atingido o perfil esperado pela OMS para assistência a saúde bucal infantil.

Background. The etiology of dentine hypersensitivity (DH) is still inconclusive and there are few studies concerning it in children. Aim. To evaluate clinical, dietary, and salivary variables in children with DH complaints. Design. Forty-eight children were asked about DH. Data regarding dietary habits were collected from the children’s parents and an examination was performed to determine dental erosion. Dental biofilm was estimated by oral hygiene status, according to Greene and Vermillion’s Simplified Oral Hygiene Index (OHI-S). Whole saliva was collected under mechanical stimulation and evaluated salivary flow rate, initial pH, buffer capacity, and calcium and phosphate concentrations. The temperature of soft drinks, drinking method, sense of bitter taste, and other variables were also determined. Possible factors associated with DH were analyzed by univariate and multiple Poisson regression analyses. The prevalence ratio (PR) values and 95% confidence intervals (95% CI) were calculated. Results. DH was associated with the presence of dental erosion (PR; 95% CI = 2.23; 1.05 to 4.71) and salivary flow rate (2.49; 1.05 to 5.91). When the presence of erosion was not included, other variables were retained as follows: bitter taste (2.36; 1.38 to 4.03), OHI-S (0.47; 0.23 to 0.97). Conclusion. DH in children is associated with factors related to dental erosion.
