The effect of socioeconomic aspects and dental history on pediatric patients' dental anxiety

Abstract This study aimed to characterize the profile of dental anxiety in pediatric patients, identifying the effect exerted by socioeconomic factors using dental data. A cross-sectional study design with a sample of 120 children aged 7-12 years old was used. Data relating to anxiety levels prior to dental care, socioeconomic aspects (family income, education level, child's school type), and child's dental history (previous dental appointments, previous treatment, caries experience) were collected. Additionally, participants completed the Brazilian version of the Children's Fear Survey Schedule- Dental Subscale (B-CFSS-DS) to assess dental anxiety. Descriptive analyses, chi-squared (X 2 ) tests, and Mann-Whitney U tests were performed, with a significance level of 5%. A total of 51 boys (42.5%) and 69 girls (57.5%) were included. There was no significant difference in dental anxiety between them. However, younger children had higher mean B-CFSS-DS scores (p = 0.036, Mann-Whitney). A higher prevalence of dental anxiety was found in participants from low-income families (p = 0.012, X 2 ) and in patients who did not receive endodontic treatment (p=0.034, X 2 ). Higher mean B-CFSS-DS scores were also observed in participants who did not receive endodontic treatment (p=0.001, Mann-Whitney) compared with those that did receive endodontic treatment. No relationship was found between education level, patient school type, first dental appointment, caries experience, and dental anxiety data. Younger children presented a profile of greater dental anxiety. Socioeconomic factors and dental data exerted some effect on dental anxiety, where children from low-income families and those not subjected to endodontic treatment displayed higher rates of dental anxiety.

Ácaros (Arachnida, Acari) de plantas ornamentais na região noroeste do estado de São Paulo, Brasil: inventário e descrição dos sintomas causados pelos fitófagos / Mites (Arachnida, Acari) on ornamental plants in northwestern São Paulo, Brazil: occurrence and injury caused by phytophagous species

No presente trabalho foram estudados os ácaros associados a plantas ornamentais de praças, ruas e jardins residenciais, no município de Ilha Solteira, SP. Foram amostradas folhas de 20 espécies de plantas e alguns representantes das morfoespécies de ácaros encontrados foram montados em lâminas de microscopia com o meio de Hoyer, para posterior identificação sob microscópio óptico com contraste de fases. Foram registradas 23 espécies pertencentes a 15 gêneros de oito famílias. Dessas espécies, 13 são fitófagas, nove predadoras e uma de hábito alimentar não determinado. A família com maior riqueza de ácaros foi Tetranychidae, com nove espécies, sendo uma delas registrada pela primeira vez após a descrição original e outra pela primeira vez no Brasil. Lorryia formosa Cooremann, 1958 (Tydeidae) foi a que ocorreu em maior número de hospedeiros. As plantas com as maiores riquezas de ácaros foram Lagerstroemia indica L., Mussaenda alicia Hort. e Tabebuia sp., com seis espécies registradas em cada uma.

Phytophagous mites living on ornamental plants growing in parks, streets and residential gardens from Ilha Solteira, State of São Paulo, were studied. Leaves of 20 plant species were sampled and some specimens of the different morphospecies found were mounted in microscopy slides with Hoyer's medium for posterior identification under phase contrast microscope. Twenty three species belonging to 15 genera of eight families were recorded. From these, 13 species are phytophagous, nine are predator and one is of unknown feeding habits. The family Tetranychidae presented the highest richness, with nine species registered, being one of these recorded for the first time after the original description and another one being registered for the first time in Brazil. Lorryia formosa Cooremann, 1958 (Tydeidae) occurred on the highest number of hosts. The host plants that harbored the highest number of mite species were Lagerstroemia indica L., Mussaenda alicia Hort. and Tabebuia sp., with six species recorded on each.

Uso do bioterápico preparado a partir do precipitado da vacina tríplice na prevençäo dos efeitos adversos locais produzidos pela adjuvante hidróxido de alumínio existente no precipitado da vacina / Use of the biotherapic prepared to set out of the precipited triple vaccine on prevent of the adverse effects make of adjuvant allumin hidroxid exists at the vaccin precipited

Dentro do capítulo conhecido como cinética de eliminaçäo, fizemos o presente estudo preparando medicamento a partir do precipitado da vacina tríplice na 30 CH, com o objetivo de verificar a açäo preventiva sobre os efeitos adversos locais produzidos pelo adjuvante hidróxido de alumínio existente no precipitado da vacina.
