Introduction: Tooth erosion is the irreversible loss of dental hard tissues caused by acids and/or chelation without bacterial involvement. Many studies showed that there is an increase of tooth ...erosion in population and that it is related to the consumption of soft drinks, including processed fruit juices. Objective: The aim of this study was to evaluate the pH, buffering capacity (BC), total carbohydrates and sucrose in 15 sugar-free and light processed fruit juices. Material and methods: The pH was determined with a Mettler Toledo 320 pH meter. The BC was determined by titration, adding 0.1 N NaOH in 10 mL of each drink until reaching a pH level of 7.0. The total carbohydrates were determined using the phenol sulfuric method, while the sucrose was determined through the incubation of each sample with the invertase enzyme. Results: The average value of pH was 2.61 (±0.29). The processed fruit juices analyzed needed, in average, 6.2 mL (±1.9) of NaOH in order to increase the pH to 7.0. The total carbohydrates showed to be according to the values presented in the labels. The sucrose content verified in each drink was very low and varied from 0.60 to 0.93 g / 200 mL. Conclusion: This study showed that the 15 drinks analyzed had low pH and erosive potential, once most juices presented high BC. The sucrose presented in each drink was very low, suggesting that they are not cariogenic. Nevertheless, further studies that demonstrate the action of these juices in the dental surface are required.
PURPOSE: The purpose of this study was to evaluate the presence of signs and symptoms of temporomandibular disorders (TMD) in children with headaches in a neuropediatric ambulatory. METHOD: Fifty ...patients between 4 and 18 years of age were examined: 31 had headaches (24 migraine, 4 tension type and 3 unspecific headache) and 19 formed the control group. The data collection was comprised of a structured questionnaire answered by the children's parents, and a subjective evaluation about the children’s emotional state. A specific questionnaire for TMD was applied, followed by a clinical dental examination of the children. As signs of TMD, mouth opening limitation, mandibular trajectory deviation in opening mouth, and joint noise were considered. As symptoms, pain on palpation of masseter and temporal muscles and on the poromandibular joint. RESULTS: A significant increase in signs and symptoms of TMD was found in patients with headaches when compared to the control group. There was also a significant difference in signs and symptoms of TMD according to age (increased with age) and emotional state (tense> calm). CONCLUSION: There is a higher frequency of TMD in pediatric patients with headaches; thus, it is important to look for TMD signs and symptoms in this population.OBJETIVO: Avaliar a presença de sinais e sintomas de disfunção temporomandibular (DTM) em crianças com cefaléias em um ambulatório de neuropediatria. MÉTODO: Foram examinados 50 pacientes com idade entre 4 e 18 anos, 31 com cefaléias (24 com enxaqueca, 4 com cefaléia tensional e 3 com cefaléia inespecífica) e 19 do grupo controle. Os dados compreenderam um questionário estruturado respondido pelos pais e uma avaliação subjetiva sobre o estado emocional das crianças. Foi aplicado um questionário específico para DTM e realizado um exame clínico dental. Foram considerados como sinais de DTM: limitação da abertura bucal, desvio da trajetória ao abrir a boca e ruído articular. Quanto aos sintomas, foram considerados: dor à palpação dos músculos masseter e temporal e na articulação temporomandibular. RESULTADOS: Foi encontrado um aumento significante de sinais e sintomas de DTM em pacientes com cefaléias quando comparados com o grupo controle. Houve, também, uma diferença significante de sinais e sintomas de DTM de acordo com a idade (aumento com a idade) e estado emocional (tenso>calmo). CONCLUSÃO: Há maior freqüência de sinais e sintomas de DTM no grupo de pacientes pediátricos com cefaléias, sendo importante avaliar essa patologia nessa população.
OBJETIVO: Relatar o caso de um paciente com tetralogia de Fallot e sua condição bucal. DESCRIÇÃO DO CASO: Paciente do gênero masculino atendido no Curso de Especialização em Odontopediatria da Escola ...de Aperfeiçoamento Profissional da Associação Brasileira de Odontologia da seção Paraná dos cinco aos sete anos de idade. O exame clínico intrabucal inicial revelou quadro de cárie severa da infância. Durante o acompanhamento, verificou-se a erupção dos primeiros molares permanentes com a presença de defeitos de desenvolvimento de esmalte e perda de estrutura dental. À anamnese, a mãe relatou que o paciente foi portador de tetralogia de Fallot e que a cirurgia corretora foi realizada com um ano e 11 meses de idade. COMENTÁRIOS: A formação do esmalte dental dos primeiros molares permanentes ocorre a partir do primeiro mês de vida e é finalizada entre dois e quatro anos de idade. Neste caso, tal etapa coincidiu com o período anterior à cirurgia para correção da tetralogia de Fallot, fato que pode ter interferido negativamente no processo de mineralização dos primeiros molares permanentes. Os defeitos de desenvolvimento do esmalte podem levar a perda de estrutura dental, favorecendo o aparecimento da cárie dentária. Dessa forma, o odontopediatra deve realizar um diagnóstico precoce dessas alterações e intervir preventivamente para evitar a perda de tais dentes. Uma anamnese bem detalhada e a maior interação entre pediatras e odontopediatras podem proporcionar melhor acompanhamento de crianças com fatores de risco para apresentar defeitos de desenvolvimento do esmalte dentário.
OBJECTIVE: To report a case of a child with tetralogy of Fallot and his oral conditions. CASE DESCRIPTION: A male patient was assisted at the Pediatric Dentristry Specialization Course of the Brazilian Dentistry Association in the State of Paraná, Brazil, from five to seven years old. At the first intrabucal examination, the child presented a severe caries disease. During their treatment, enamel developmental defects were detected in the first permanent molar tooth, with loss of enamel structure. His mother reported that the patient had a surgical correction of tetralogy of Fallot cardiac malformation when he was 23 months old. COMMENTS: The enamel development of the first molar starts in the first month of life and ends around two to four years old. In this patient, the period of mineralization of the first molar was coincident with the period prior to the surgical correction of the cardiac problem. Probably, the development of dental enamel was impaired by the systemic repercussion of this congenital anomaly. Enamel developmental defects can present loss of dental structure, increasing the risk of caries. Therefore, the pediatric dentists should diagnose dental enamel developmental defects early, in order to prevent serious damages to the teeth. A detailed anamnesis and a good interaction between pediatricians and pediatric dentists will provide a better follow-up of children at risk of having dental enamel developmental defects.
Purpose: This study evaluated the perception, diagnosis, and attitudes of child abuse among Brazilian pediatric dentists. Methods: Data, collected through a survey sent to 212 pediatric dentists in ...Curitiba, Brazil, included perceived knowledge about signs of child abuse,
whether they had seen and reported it, and knowledge of their obligation to report, how, and to whom. Results: The response rate was ~33%. The youngest group was significantly more likely to report cases than the group with more than 18 years since graduation. Fifty-five percent of
the professionals thought they are able to identify child abuse, 36% thought they were unable, and 9% did not know. Although 73% knew that reporting incidents of abuse is compulsory, only 48% responded that they would report cases of abuse to the relevant authorities. Although 36% of the pediatric
dentists reported to have seen suspected cases of abuse, only approximately 12% reported such cases to authorities. Signs of abuse most frequently mentioned were hematoma throughout the body (61%) and behavioral changes (53%). Lesions on the face, mouth, and teeth were cited by only 17% of
the professionals. Conclusion: More information is needed in undergraduate dental schools and among pediatric dentists to recognize and report child abuse.
Violence against children and adolescents is a public health issue worldwide that threatens physical and mental wellbeing and causes irreparable harm. Reports on this violence are an essential way to ...prevent it and to protect the children and adolescents. Thus, the objective of the present study was to evaluate the prevalence of physical injuries that occur in domestic environments and reported to the Child and Adolescent Protection Network. This retrospective study was conducted at the Epidemiology Center of the Municipality of Curitiba. A total of 10,483 reports for the years 2010 (5,112) and 2011 (5,371) were analyzed and from them were selected reports of physical injuries that occurred in the family environment. The children and adolescents were 0-17 years old, comprising 322 cases of physical abuse within the family in 2010. Out of these, 57.1% were male and 42.9% were female, and 58% (187) presented head and neck injuries. There were 342 reports in 2011, 49% were male and 51% were female; head and neck injuries corresponded to 65% (222) of the reported cases. The prevalence of injuries increased by 6% and head and neck injury increased by 19% between 2010 and 2011. It may be concluded that physical abuse is associated with a high prevalence of head and neck injury, which is easily observed by the health and education professionals. Notification organs should be created in Brazilian hospitals and health centers, which is essential to conduct epidemiological surveillance and appropriate policies.
The aim of this study was to evaluate the shear bond strength of rebonded ceramic brackets after subjecting the bracket base to different treatments. Seventy-five premolars were selected and randomly ...distributed into five groups (n=15), according to the type of the bracket surface treatment: I, no treatment, first bonding (control); II, sandblasting with aluminum oxide; III, sandblasting + silane; IV, silica coating + silane; and V, silicatization performed in a laboratory (Rocatec system). The brackets were fixed on an enamel surface with Transbond XT resin without acid etching. The brackets were then removed and their bases were subjected to different treatments. Thereafter, the brackets were fixed again to the enamel surface and the specimens were subjected to shear bond strength (SBS) test. The adhesive remnant index (ARI) was then evaluated for each specimen. Data were subjected to ANOVA and Tukey's tests (α=0.05). A statistically significant difference was observed only between Rocatec and the other groups; the Rocatec group showed the lowest SBS values. The highest SBS values were observed for group 1, without any significant difference from the values for groups II, III and IV. Most groups had a higher percentage of failures at the enamel-resin interface (score 1). It was concluded that the surface treatments of rebonded ceramic brackets were effective, with SBS values similar to that of the control group, except Rocatec group.
The aim of the present study was to compare trait anxiety and dental anxiety among children, adolescents and their parents.
A cross-sectional study was conducted involving 100 patients from the ...Pediatric Dentistry Clinic of the Federal University of Parana (Brazil) between the ages of 8 and 17 years (mean age: 10.3; standard deviation: 2.03) and their parents, who responded to Corah's Dental Anxiety Scale (DAS) and the Trait Anxiety Scale. The data were analyzed using the Mann-Whitney test, analysis of variance and both Pearson's and Spearman's correlation coefficients.
Ninety percent of children and adolescents and 76% of the parents had moderate anxiety based on the DAS score. Seventy-four percent of children and adolescents and 72% of the parents had moderate anxiety based on the Trait Anxiety Scale score. The trait anxiety and dental anxiety scores were correlated among the adults (rs = 0.64) and children (r = 0.52), whereas no correlation between scores was found among the adolescents. Associations were also found between children's trait anxiety and the dental and trait anxiety of their parents (both r = 0.43).
A moderate degree of dental anxiety was prevalent among the children, adolescents and parents who took part in this investigation, with correlations demonstrated between some trait anxiety and dental anxiety scores.
