Avaliação da associação entre os indicadores de saúde bucal, os aspectos socioeconômicos e crianças com sinais clínicos orofaciais indicativos de respiração oral crônica

Purpose To evaluate whether clinical and sociodemographic indicators of oral health in school-age children (from 8 to 12 years) with mixed dentition are associated with oral breathing. Methods Fifity-five children selected from a public school in the city of Cachoeira do Sul (RS) were evaluated. After obtaining parental consent, a trained speech pathologist performed examinations to identify children with orofacial clinical signs indicative of oral breathing. For the oral health exams, dental students underwent training and calibration according to the criteria of the World Health Organization for epidemiological surveys. In addition to the intra-oral examinations, socioeconomic and demographic data were collected from the parents of the children using a questionnaire. Results Although the prevalence of children with mouth breathing symptoms was notable, it was lower than that reported in the literature. No difference was observed between the groups (mouth breathers and nose breathers) regarding socioeconomic variables associated with the tested dental aspects. Conclusion Oral breathing was not associated with clinical indicators of oral health such as caries, visible plaque, and gingival bleeding. Further, no association was found between sociodemographic variables and oral breathing.

A Longitudinal Study of Early Childhood Caries and Associated Factors in Brazilian Children

Early childhood caries (ECC) affects children all over the world and has high prevalence and severity in preschool children. Different social, biological and behavioral factors compose a network of causal factors for ECC. The aim was to evaluate the association between socioeconomic variables and caries at baseline, and the presence of Streptococcus mutans and Lactobacillus spp. microorganisms with the progression of caries lesions after two years of follow-up in a group of children. At baseline, 163 children (3-4 years old) living in the areas of 12 primary care services of the Hospital Group Conceição (GHC, Porto Alegre, RS, Brazil) were evaluated. After two years, 119 children were re-evaluated. Clinical examinations were conducted by calibrated examiners using the ICDAS criteria. A sociodemographic questionnaire was applied to the childrens parents and saliva samples were collected from the children for microbiological analysis. Descriptive statistics and multivariate Poisson regression analysis were performed in the statistical analysis. The factors associated with the caries progression were marital status of mothers (p=0.040), higher S. mutans counts (p=0.031) and the presence of cavitated lesions at baseline (p<0.001). The caries lesions progression in preschool children enrolled in primary health care was directly associated with marital status, presence of cavitated lesions at baseline and higher S. mutans counts at two-year follow-up.

Pulpotomy in deciduous tooth with mineral trioxid aggregate

Several medicines have been tested and used in the conservative pulp therapy of deciduous teeth, however, the formocresol has being the elected material in the pulpotomies, even not assisting the biocompatibility demands and promoting the fixation of the vital pulp tissue and not its repair. After Mineral Trioxide Aggregate (MTA) appearance as a material with physico-chemical properties that promotes the tissue repair, allied to other important properties, such as the antimicrobial action and the biocompatibility to the pulpal tissues, a new alternative material appeared for the dentistry. The aim of this study was to report the effect of MTA in a pulpotomy of deciduous molar, and its 1-year follow-up. The pulpotomy was made with MTA in the tooth 85 in a 5-year-old patient. The results obtained were quite favorable, demonstrating clinical and radiographic success, as well as absence of painful symptomatology reported by the patient. In spite of the little time of follow-up of the treated deciduous tooth, MTA has a great biological potential and could be an alternative material to be used in the pulpotomies of deciduous teeth.
