OBJECTIVES: This study aimed to determine the accuracy of the Breath-Alert™ portable breath meter (BA) for the detection of halitosis in children and adolescents, considering the organoleptic test (OT) as the gold standard in this assessment. METHODS: A cross-sectional study was conducted on 150 children (aged 6-12 years). OT was performed by three independent examiners on a single occasion, obtaining three scores of 0-5 points on the Rosenberg’s organoleptic scale. The median of the three evaluations for each child was used for analysis. BA was used according to the manufacturer’s instructions, with breath odor scored from 0-5 points. Scores ≥2 on both tests were considered indicative of halitosis. RESULTS: A total of 26 (17.3%) and 23 (15.3%) children were detected with halitosis on the OT and BA tests, respectively. The sensitivity and specificity of the BA scores for the detection of halitosis were 80.76% and 98.38%, respectively. The positive and negative predictive values for BA were 91.3% and 96.06%, respectively. CONCLUSION: In the present study involving children, who require fast, practical examinations, BA proved to be an auxiliary tool to OT for the detection of halitosis in the practice of pediatric dentistry, demonstrating high sensitivity and specificity.

RESUMO Objetivo analisar o uso de álcool, tabaco e maconha e suas repercussões na qualidade de vida de adolescentes que cursam o ensino médio. Método Estudo analítico, com amostra de 169 estudantes de Ensino Médio. Foi aplicado um questionário contendo avaliação sociodemográfica, Teste de triagem do envolvimento com álcool, cigarro e outras substâncias e Escala de avaliação da qualidade de vida. Os dados foram analisados por meio de estatísticas descritivas e inferenciais. Resultados Os principais resultados mostraram que nos últimos três meses o uso de tabaco foi associado a uma qualidade de vida considerada ruim/muito ruim, o não uso com qualidade de vida muito boa/boa e satisfação com a saúde. Os estudantes que não usaram álcool consideram sua qualidade de vida muito satisfatória ou satisfatória em relação ao ambiente. Conclusão e implicações para a prática Foi confirmada a hipótese da relação entre uso de substâncias psicoativas e aspectos da qualidade de vida.

ABSTRACT Objective To analyze the use of alcohol, tobacco and marijuana and their repercussions on the quality of life of high school adolescents. Method Analytical study with sample of 169 high school students. We applied a questionnaire containing sociodemographic evaluation, screening test of the involvement with alcohol, cigarette and other substances, and Quality of life assessment scale. Data were analyzed using descriptive and inferential statistics. Results The main results showed that in the last three months, tobacco use was associated with poor / very poor quality of life, no use with very good / good quality of life and health satisfaction. Students who did not use alcohol consider their quality of life to be very satisfactory or satisfactory in relation to the environment. Conclusion and implications for practice The hypothesis of the relationship between psychoactive substance use and aspects of quality of life was confirmed.

AIM: To evaluate the clinical status of permanent first molars and associations with dental caries, gingival bleeding, dental fluorosis and malocclusion. METHODS: An observational study was carried out in a rural community denominated Morro do Saboó in the city of São Roque, state of São Paulo, Brazil. A total of 194 children aged seven to ten years were examined for dental caries using the index proposed by the World Health Organization. Other conditions were determined using the Gingival Alterations Index, Dean's Index and Dental Aesthetic Index. The chi-squared test was used for the statistical analysis of the data. RESULTS: A total of 85.5% of the sample exhibited gingival bleeding and 69.9% exhibited malocclusion. A total of 53.6% had a clinical aspect of normality with regard to dental fluorosis. There was a predominance of sound teeth in the upper arch and teeth with carious lesions in the lower arch. No significant differences were found between sexes regarding gingival bleeding, dental fluorosis or malocclusion. Significant associations were found between tooth status and oral alterations (gingival bleeding, malocclusion and fluorosis) in teeth 16, 26 and 46 and between tooth status and gingival bleeding in tooth 36 (p<0.001). CONCLUSIONS: Caries activity in the permanent first molars was mainly associated with dental fluorosis and malocclusion. Strategies aimed at health promotion should be adopted on a large scale to minimize the prevalence of oral diseases.

OBJECTIVE: To determine whether there is a correlation between halitosis and mouth breathing in children. STUDY DESIGN: Fifty-five children between 3 and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. A descriptive analysis was conducted on the degree of halitosis in each group. The chi-square test was used for comparison between groups, with a 5% level of significance. RESULTS: There was a significantly greater number of boys with the mouth-breathing pattern than girls. A total of 23.6% of the participants had no mouth odor, 12.7% had mild odor, 12.7% had moderate odor and 50.9% had strong odor. There was a statistically significant association between halitosis and mouth breathing. CONCLUSIONS: The occurrence of halitosis was high among the children evaluated, and there was a statistically significant association between halitosis and mouth breathing.

Uno de los principales objetivos en el manejo del paciente pediátrico con caries es la utilización de técnicas no invasivas, que permitan el tratamiento de la patología dentaria sin afectar el comportamiento del niño. El propósito de este estudio fue evaluar la reacción de niños y registrar su sensación mientras recibían tratamiento de caries dentinal utilizando elementos rotatorios de baja velocidad, en comparación al tratamiento químico mecánico de caries dentinal en dentición decidua. Participaron en el estudio 36 niños, entre 4 y 8 años de edad. Se utilizó un diseño de estudio al azar de sección cruzada de manera tal que cada niño sirviera como su propio control, recibiendo cada tratamiento en cada lado de la misma arcada. Cada paciente era asignado al azar para recibir el tratamiento con elementos rotatorios o tratamiento químico mecánico en la primera visita, administrándosele el restante en la segunda visita. Luego de su tratamiento, todos los dientes fueron obturados con ionómero de vidrio fotopolimerizable. Para la evaluación objetiva de la reacción de los niños se aplicó la Escala de Comportamiento ante el Dolor Modificada. Inmediatamente después de realizado el tratamiento, se solicitaba a los niños que llenaran el formulario que contenía la Escala Facial para Registro del Dolor de Wong-Baker (Facial Pain Scale) para la evaluación subjetiva. El tratamiento químico mecánico demostró ser un procedimiento mejor aceptado por los pacientes pediátricos que el tratamiento con elementos rotatorios de baja velocidad

One of the main objectives during the pedodontics assistance is the use of noninvasive techniques, that allow the treatment of the dental caries without affecting the behavior of the child. The aim of this study was to evaluate the reaction of children and to register its sensations during the treatment of dental caries in deciduous teeth, using low speed cutting rotatory instruments in comparison to the chemical and mechanical caries removal treatment. 36 children participated in the study, between 4 and 8 years of age. A cross section study design was used and each child served like his own control, receiving the two treatment in teeth of the same arches. Each patient one was selected randomly to receive the treatment with rotatory instruments or the chemical and mechanical treatment in the first visit, administered him to it the rest treatment in the second visit. After their treatment, all the teeth were restorated with light-curing glass ionomer. For the objective evaluation of the reaction of the children the Behavior Scale in the Modified Pain was applied. Immediately after the treatment, one asked for the children who filled the form that contained the Wong-Baker’s Face Scale for Registry of the Pain (Face Pain Scale) for the subjective evaluation. The chemical-mechanical treatment demostrated to be more accepted for the children in comparasion to the treatment with cutting rotatory istruments
