Very little is known about mothers' beliefs concerning children's refusal of dental treatment. This qualitative study aimed to explore mothers' perceptions of their children's refusal to submit to dental treatment. Semistructured interviews were conducted with 14 mothers of 4-12-yr-old children resistant to dental treatment who were attending two pediatric dentists. Thematic content analysis was used to interpret the data. From this, three categories were developed and labeled origins of child behavior, caregiver attitudes, and the culture of resistance. The origins of the children's behavior were related to the childs' temperament, behavior disorders, lack of affection, level of development, and refusal to submit to health procedures or other situations. Caregiver's attitudes included discipline, protection, incoherence, partnership in dental treatment, and mother-child feeling. The culture of resistance referred to the parents' or guardians' refusal of dental treatment and the mothers' recognition of this. In conclusion, the wide variety of mothers' accounts reinforced the idea that every child is unique, and it is not possible to standardize child behavior models in a dental setting.

ABSTRACT:The effectiveness of oral midazolam in pediatric dentistry is controversial. This randomized, controlled, crossover, double blind clinical trial was conducted in order to study the effect of midazolam, used either alone or in association with hydroxyzine, during child dental treatment. Thirty seven dental sedation sessions were carried out on 11 ASA I uncooperative children less than five years-old. In each appointment children were randomly assigned to groups: P -placebo, M -midazolam (1.0 mg/kg), or MH -midazolam (0.75 mg/kg) plus hydroxyzine (2.0 mg/kg). Vital signs (blood pressure, breathing rate, pulse and oxygen saturation) and behavior parameters (consciousness, crying, movement, overall behavior) were evaluated every 15 minutes. Friedman and Wilcoxon statistical tests were used to compare groups and different moments in the same group. Normal values of vital signs were usually registered. Heart rate increased in groups P and M as the session went on. Group M presented less crying and movement at the first 15 minutes of treatment. Group MH caused more drowsiness at the beginning of the session. Overall behavior was better in group M than in groups P or MH. Group M produced effective sedation in 77% of the cases, and group MH did so in 30.8%. It was concluded that midazolam was effective and safe, and its association with hydroxyzine did not lead to additional advantages in pediatric dental sedation.

Conduziu-se um ensaio clínico controlado, cruzado e duplo-cego para comparar o efeito sedativo em Odontopediatria da administração oral do midazolam, associado ou não à hidroxizina. Trinta e sete sessões foram realizadas em 11 crianças menores de cinco anos, ASA I. Em cada atendimento, os pacientes receberam aleatoriamente o medicamento conforme os grupos: P -placebo, M -midazolam (1,0 mg/kg); MH -midazolam (0,75 mg/kg) associado à hidroxizina (2,0 mg/kg). Os sinais vitais (pressão arterial, freqüência respiratória, pulso e saturação de oxigênio) e os parâmetros comportamentais (consciência, choro, movimento, comportamento geral) foram avaliados a cada 15 minutos. As comparações entre grupos e entre momentos de atendimento num mesmo grupo foram estabelecidas estatisticamente através dos testes Friedman e Wilcoxon. Os grupos P, M e MH não diferiram quanto aos sinais vitais, os quais se mantiveram dentro de valores aceitáveis. A freqüência cardíaca aumentou nos grupos P e M com o transcorrer da sessão. O grupo M esteve associado a menos choro e movimento nos primeiros 15 minutos de tratamento. O grupo MH apresentou mais sonolência no início da sessão. O comportamento geral foi melhor em M do que em P e MH. M produziu sedação efetiva em 77% dos casos, e MH em 30,8%. Concluiu-se que o midazolam foi efetivo e seguro, e que sua associação à hidroxizina não repercutiu em vantagens adicionais na sedação odontopediátrica.

Chloral hydrate and hydroxyzine are a drug combination frequently used by practitioners to sedate pediatric dental patients, but their effectiveness has not been compared to a negative control group in humans. The aim of this crossover, double-blinded study was to evaluate the effect of these drugs compared to a placebo, administered to young children for dental treatment. Thirty-five dental sedation sessions were carried out on 12 uncooperative ASA I children aged less than 5 years old. In each session patients were randomly assigned to groups P (placebo), CH (chloral hydrate 75 mg/kg) and CHH (chloral hydrate 50 mg/kg plus hydroxyzine 2.0 mg/kg). Vital signs and behavioral variables were evaluated every 15 min. Comparisons were statistically analyzed using Friedman and Wilcoxon tests. P, CH and CHH had no differences concerning vital signs, except for breathing rate. All vital signs were in the normal range. CH and CHH promoted more sleep in the first 30 min of treatment. Overall behavior was better in CH and CHH than in P. CH, CHH and P were effective in 62.5%, 61.5% and 11.1% of the cases, respectively. Chloral hydrate was safe and relatively effective, causing more satisfactory behavioral and physiological outcomes than a placebo.

ObjectiveModerate sedation has limits in managing children's behavior. Existing literature lacks insight into parental perceptions about the topic. This study aimed to understand mothers' perceptions concerning sedation after their children undergone dental treatment under sedation. MethodsTwelve mothers and one godmother of 1.3-8.4 year-old children with definitely negative behavior in the dental chair, who had dental treatment under oral sedation, were in depth interviewed according to a semi-structured guide. Responses were analysed using a thematic content method and deductive approach. Two general themes were addressed: "good facet" and "poor facet" of pediatric dental sedation. Results Analysis of interview transcripts indicated that participants perceived pediatric dental sedation according to two main analytical categories: the "good facet" and the "poor facet". The good facet included advantages of the procedure (e.g. safety, effective behavior management), rapport and completion of the treatment that was initially planned. The poor facet related to limitations of moderate sedation (when child kept struggling) and their own anxiety during the procedure. ConclusionDespite their own stress, mothers were satisfied with this pharmacological method of behavior management.

edation is an option for controlling fear and anxiety related to a visit to the dentist. The goal of this study was to capture, by means of a questionnaire, the perceptions of twenty dentists, twenty dental students and twenty lay people concerning the use of sedatives in a dental environment. The responses were evaluated using the quantitative-interpretative method. Dentists: 75% had knowledge of sedatives in a dental setting, but their actual use was mentioned by only three. As far as the use of sedatives by dentists is concerned, one considered it "risky" and 19 were favorable. Two affirmed that sedation does not present risks. Eighteen said they would be able to react to a medical emergency. Dental students: 60% said they were aware of the topic, in theory. Nineteen expressed interest in the topic. Fifteen claimed there were risks associated with the technique. Twelve (60%) have the theoretical knowledge to deal with a medical emergency in the dental office. Lay public: Seven (35%) responded that they felt some discomfort during dental treatment, because of fear (n=6) and equipment noise (n=2). Five said they would go to the dentist more often if there was a way to reduce the discomfort. Half of those interviewed indicated that they knew what sedation was. Sixteen favored using it for dental treatment. Seven thought that there were no risks when sedation is carried out. It was concluded that few participants in any of the three categories felt confident about the topic, though they demonstrated interest. The population in general felt optimistic, while practicing dentists and dental students complained of a lack of exposure to the subject at dental school.
