Influ?ncia de fatores cl?nicos e socioambientais na sa?de bucal de crian?as pr?-escolares: um coorte de 3 anos

Linha de pesquisa: Epidemiologia e controle das doen?as bucais.O objetivo desse estudo de coorte foi avaliar o risco de fatores cl?nicos e socioambientais dos primeiros anos de vida da crian?a sobre: (1) a progress?o da c?rie dent?ria; (2) a presen?a de dor de dente; (3) a ocorr?ncia de m? oclus?o; (4) o impacto na qualidade de vida relacionada ? sa?de bucal de crian?as pr?-escolares e suas fam?lias. Este estudo foi realizado com 151 pares de m?es e crian?as que participaram de um estudo transversal realizado no ano de 2014 na cidade de Diamantina, Minas Gerais. Durante o baseline (2014) essas crian?as apresentavam de 1 a 3 anos de idade e foram avaliadas clinicamente para verificar a presen?a de c?rie dent?ria por meio dos crit?rios do Sistema Internacional de Avalia??o e Detec??o de C?rie Dent?ria (ICDAS) de placa dent?ria vis?vel, de m? oclus?o e de traumatismos dent?rios. As m?es tamb?m foram avaliadas clinicamente para verificar a presen?a de c?rie dent?ria por meio dos crit?rios da Organiza??o Mundial de Sa?de. Foram aplicados tr?s question?rios ?s m?es sob a forma de entrevista: um question?rio para avalia??o da qualidade de vida relacionada ? sa?de bucal, a vers?o brasileira do Early Childhood Oral Health Impact Scale (B-ECOHIS), o Dental Anxiety Scale (DAS) e um question?rio que abordava aspectos socioambientais da fam?lia al?m de informa??es relativas ?s crian?as e seus h?bitos. Todas as m?es foram orientadas acerca das condi??es bucais de seus filhos e as crian?as foram encaminhadas para atendimento odontol?gico. Ap?s tr?s anos (T1) as crian?as foram reavaliadas clinicamente e as m?es responderam novamente ao B-ECOHIS, ao DAS, al?m de responderem a um question?rio para avalia??o de dor de dente, a vers?o brasileira do Dental Discomfort Questionnaire (DDQ-B). A an?lise de dados foi realizada atrav?s do Statistical Package for the Social Sciences (SPSS) vers?o 22.0, e incluiu a descri??o de frequ?ncia das vari?veis, teste qui-quadrado, teste Wilcoxon e regress?o hier?rquica de Poisson. Crian?as que possu?am pelo menos um dente com c?rie cavitada no baseline, apresentaram maior risco de progress?o de outras les?es cariosas. Foram fatores de risco para a ocorr?ncia de dor de dente em T1, a presen?a de c?rie dent?ria cavitada e a maior aglomera??o familiar no baseline. A presen?a, no baseline, de c?rie dent?ria cavitada e do h?bito de suc??o de dedo foram fatores determinantes da presen?a de m? oclus?o em T1. Incremento de c?rie severa, tratamento odontol?gico e escore do B-ECOHIS no baseline foram associados ? piora na qualidade de vida. Conclui-se que c?rie dent?ria, suc??o de dedo e maior aglomera??o familiar s?o fatores de risco para piores resultados em sa?de bucal na idade pr?-escolar. Incremento de c?rie severa, aus?ncia de tratamento dent?rio e menor escore do B-ECOHIS no baseline foram fatores de risco para a piora na qualidade de vida.Tese (Doutorado) ? Programa de P?s-Gradua??o em Odontologia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017.The aim of this cohort study was to evaluate the risk of clinical and socioenvironmental variables in the first years of the child's life: (1) in the progression of dental caries; (2) in the presence of toothache; (3) in the occurrence of malocclusion; (4) in the impact on quality of life related to oral health of preschool children and their families. This study was conducted with 151 pairs of mothers and children who participated in a cross-sectional study conducted in the city of Diamantina, Minas Gerais, in 2014. During the baseline (2014), these children presented 1 to 3-years-old and were clinically evaluated to verify the presence of dental caries using the International Dental Caries Assessment and Detection System (ICDAS) for dental plaque, malocclusion and dental trauma. Mothers were also evaluated clinically to verify the presence of dental caries using World Health Organization criteria. Three questionnaires were applied to the mothers in the form of interviews: a questionnaire to assess the quality of life related to oral health, the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS), the Dental Anxiety Scale (DAS) and a questionnaire that addressed socioenvironmental and demographic aspects of the family, as well as information about the children and their habits. All mothers were instructed about the oral conditions of their children and the children were referred to dental care. After three years (T1), the children were clinically re-evaluated and the mothers responded again to the B-ECOHIS, the DAS, and answered a questionnaire for assessing tooth pain, the Brazilian version of the Dental Discomfort Questionnaire (DDQ-B). Data analysis was performed using the Statistical Package for Social Sciences (SPSS) version 22.0, and included the frequency description of the variables, chi-square test, and Poisson hierarchical regression. Children who had at least one tooth with caries cavity in the baseline presented a higher risk of progression of other carious lesions. The presence of cavitary tooth decay and the greater familial agglomeration in the baseline were risk factors for the occurrence of tooth pain in T1. The presence, in the baseline, of cavitary tooth decay and finger suction habit were factors determining the presence of malocclusion in T1.The incidence of severe caries, absence of dental treatment and higher score of B-ECOHIS at the baseline were associated with worsening quality of life. In conclusion, tooth decay, finger suction, greater family agglomeration and the impact on the quality of life in the first years of the child's life, are risk factors for worse oral health outcomes at preschool age. The incidence of severe caries, the absence of dental treatment, and a lower score on B-ECOHIS were risk factors to worsen the quality of life
