Influence of the coloring agent concentration on bleaching gel and pulp chamber temperatures during dental bleaching

This study evaluated the Influence of the coloring agent concentration on the temperature of the gel layer and pulp chamber during dental bleaching with an LED/laser light source. Ten human incisors and a digital thermometer with K-type thermocouples were used. Using a high-speed spherical diamond bur, endodontic access was gained through openings on the lingual faces until pulp chamber was exposed. One end of the thermocouple was placed on the labial surface (immersed in bleaching gel) and the other end in the pulp chamber. The same 10 specimens were used in the 12 groups, according to the type and concentration of bleaching gel. Each bleaching gel was used in four different concentrations: manipulated without coloring, with normal quantity recommended by the manufacturer, with double the recommended amount of coloring, and with triple the recommended amount of coloring. The temperature rise was measured every 30 seconds for three minutes with a K-type thermocouple. The data were analyzed by ANOVA to examine the concentration and type of bleaching gel. This test was followed by Tukey's test, which was performed Independently for the gel at the labial surface and the pulp chamber (a = 5%). For both surfaces, values of p = 0.00 were obtained for all factors and for the Interaction between them. The varying concentrations of coloring agent produced statistically significant differences in terms of temperature increase for both the gel layer and the pulp chamber during activation.

Speech therapy intervention before dental management in patients with special needs: A case report

Fragile X syndrome is a cytogenetic abnormality related to chromosomal X. This syndrome is frequently associated to intellectual disability, psychological problems, as well as heart, skeletal and join alterations. Intraoral anomalies include malloclusion, ogival palate, cleft palate, presence of mesiodens, dental hypomineralization and abrasion of the occlusal surfaces and incisai edges. The study of characteristics of this syndrome is important for the dentist in order to guide dental treatment and prevention. The aim of this study is to present a myofunctional therapy protocol, evaluated by surface electromyography. A case of a 21 year-old young man who attended the Training Program in Dentistry for Persons with Disabilities, School of Dentistry of São José dos Campos/UNESP is reported. He underwent myofunctional therapy before dental treatment and the masticatory muscles were evaluated by surface electromyography. The exercises of myofunctional therapy consisted of active and passive simple movements of opening and closing the mouth, tongue protrusion and retrusion, digital manipulation and also by using an electric massager on intraoral and perioral region of the masseter, buccinator and orbicularis oris. Action potentials of the masticatory muscles decreased in almost all the muscles and values for the bite force and mandibular opening capacity increased. This study showed that brief and immediate myofunctional therapy optimized clinical practice with positive repercussion on dental care.

Retardo na procura do tratamento odontológico e percepção da saúde bucal em mulheres grávidas

The objective was to assess in women with children under 5 years old what happened to your pregnancy in relation to dental care, coupled with a probable correlation between the level of their knowledge on dental health and possible reasons which lead or have led to a late seeking such treatment. The interviews were conducted in an environment of health center in the city center and the Odontoly Faculty in Araraquara. Among the interviews mothers, 57% refused the dental treatment during pregnancy. It appears on mothers that are afraid to perform a dental treatment during pregnancy. The misinformation on this issue often associated with this belief in the medical field that dental care during the first three months of pregnancy is harmful to the baby. Such information passed on to mothers leads to a hesitancy with dental treatment during this period. The educational level of mothers did not interfere in this pursuit, and 24.5% of them avoid treatment during pregnancy. The difference, however, is between those mothers of high educational level, performing oral prevention before pregnancy.

Risk factors in the mother-child relationship that predispose to the development of early childhood caries

This study focused on the risk factors in mother-child relationship that predispose babies to the development of dental caries. A prospective cohort study with 80 mother-child pairs was conducted. The mothers responded at 12, 18 and 30 months after their children's birth, to questions about variables related to diet, sucking habits, and oral care. Children were clinically examined to verify caries lesions (white spot lesions or cavitation). Data were analysed using Chi squared or Fisher's exact tests. The significance level was set at 5 %. Of the total, 3.75 % showed cavitated lesions after 18 months; 6.25 and 45 % had spot white lesions, respectively, at 18 and 30 months. The cariogenic diet was high at 12 (63.75 %) and 30 (88.75 %) months. Good oral hygiene was present in a minority of children at 12 months (46.25 %), but increased at 30 months (65 %), helping to prevent cavities and white spot lesions over this period (p = 0.0005). The variables of the blocks sucking habits and diet were not associated with caries. The lack of oral care in children was a risk factor for dental caries development.

Prevalência de cárie dentária em pré-escolares de escolas de educação infantil de Araçatuba, São Paulo

Epidemiological data on the conditions of oral health are essential for professionals in the health care plan, execute and evaluate dental programs. In Brazil, most oral health programs directs its resources to middle schools, leaving the preschool children in a secondary plan. The objective of this study was to identify the prevalence of dental caries in preschool children from 4-6 years of age from schools of child education (EMEIs) of the city of Araçatuba-SP. The study was conducted on a sample of 275 children of both genders, representative of the population of preschool children in the city of Araçatuba-SP. In order to assess the prevalence and severity of dental caries indices we used the dmft and DMFT indexes, according to the codes and standards recommended by the World Health Organization (WHO).The average dmft of 1.88 was found, comprising 78% of decayed teeth, 21% of restaured teeth and 1% with indicated extraction teeth. Regarding the permanent dentition, the average DMFT was 0.08, consisting of 71% of decayed teeth, 29% restored and 0% of missing teeth. Based on results found, there was a high caries prevalence in deciduous and permanent teeth, demonstrating the need for more dental care to the group studied.

Reflex postural control of patients with cerebral palsy for odontological assistance

Cerebral palsy (CP) describes a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain.A child with cerebral palsy may have impairments in motor control, which contributes to loss of functional abilities in posture and mobility. The severity of the impairment on the neuromuscular system determines the variations of functional mobility in children with cerebral palsy. The control of the patient, during the dental treatment, is of fundamental importance because these patients present some pathological reflexes which interfere in the odontological assistance

Para uma crítica da razão socioeducativa em entidades assistenciais

Buscou-se cartografar as instituições de assistência social que atendem à infância e à adolescência consideradas em situação de risco pessoal e social, em um município do interior do estado de São Paulo, utilizando o instrumental da análise institucional. O papel de membro do Conselho Municipal dos Direitos da Criança e do Adolescente e do Conselho Municipal de Assistência Social facultou a realização de uma análise documental nos arquivos desses Conselhos, relativa às entidades assistenciais cadastradas, tais como organizações governamentais, organizações não-governamentais e outros estabelecimentos filantrópicos. Os resultados indicam que, no universo da Assistência Social, a constelação criança/adolescente orbita em torno do astro-rei socioeducativo. Todas as atividades desenvolvidas nas entidades parecem recobertas por esse significantemestre, que conota dimensões pedagógicas e terapêuticas, educativas e corretivas, de vigilância e de prevenção, promovendo controle e normalização.
