Objective The aim of the present study was to evaluate factors associated with the clinical consequences of untreated dental caries in children attending public and private preschools. Methods A cross‐sectional study was conducted with a complex, preschool‐based sample of 769 children, 5 years of age, from public and private preschools in the city of Campina Grande, Brazil. Clinical examinations to diagnose the consequences of untreated caries were performed using the criteria of the pufa index (p ‐ pulp exposure; u ‐ ulceration caused by movement of tooth fragments; f ‐ fistula; a ‐ abscess). The psychological factor evaluated was parental/caregiver sense of coherence (SOC), which was determined using a validated assessment tool. Sociodemographic characteristics and the use of dental services were also considered. Two examiners were trained to examine the clinical consequences of untreated dental caries. The kappa statistic demonstrated a high level of agreement for the conditions evaluated. Descriptive analysis was performed, followed by the use of an inductive decision tree (J48 algorithm; α = 5%). Results The factors associated with the clinical consequences of untreated dental caries were toothache [prevalence ratio (PR) = 12.34; 95% confidence interval (95% CI): 7.87–19.35; P < 0.001], attending a public preschool (PR = 2.38; 95% CI: 1.83–3.09; P < 0.001), parents/caregivers younger than 30 years of age (PR = 1.45; 95% CI: 1.26–1.68; P < 0.001), parents/caregivers with more than two children (PR = 1.47; 95% CI: 1.28–1.69; P < 0.001) and parents/caregivers with a weak SOC (PR = 1.13; 95% CI: 1.01–1.28; P = 0.043). Conclusion The prevalence of clinical consequences of untreated dental caries was low in the present sample and was associated with sociodemographic factors (type of preschool, caregiver's age and number of children in the family) as well as psychological factors (SOC).

Objetivo: descrever a experiência de indivíduos com deficiências matriculados em uma Associação de Pais e Amigos dos Excepcionais na utilização de serviços públicos odontológicos. Metodologia: foi realizado um estudo transversal e analítico com amostra de 121 participantes. Os responsáveis pelos alunos responderam a um formulário com informações socioeconômicas, clínicas e sobre dificuldades para utilização dos serviços odontológicos. Foi utilizado o teste qui-quadrado de Pearson para a análise dos dados assumindo como significativos valores de p<0,05. Resultados: os resultados mostraram uma maior ocorrência de indivíduos com deficiência mental 54 (44,6%), cuidados pela mãe 100 (75,2%) e já atendidos em serviços públicos odontológicos do município 62 (51,2%). Para 57 (47,1%) dos participantes atribuiu-se alguma dificuldade na utilização de serviços públicos odontológicos. Apenas o recebimento de informações sobre locais de atendimento foi associado à utilização dos serviços (p<0,05). Conclusão: A ocorrência de indivíduos com dificuldades na utilização de serviços públicos odontológicos foi alta e os responsáveis informados sobre locais para atendimento frequentaram mais estes serviços.

Background Individuals diagnosed with a rare genetic disease that affects skeletal development often have physical limitations and orofacial problems that exert an impact on oral health. The aim of the present study was to analyze the possible vulnerability to dental caries in individuals with rare genetic diseases that affect skeletal development. Methods A paired cross-sectional study was carried out with a sample of 140 individuals [70 with rare genetic diseases affecting skeletal development: mucopolysaccharidosis (MPS) ( n = 29) and osteogenesis imperfecta (OI) ( n = 41) and 70 without rare diseases] and their parents/caregivers. The participants in the first group were recruited from two reference hospitals specialized in rare genetic diseases in the city of Belo Horizonte, Brazil. All participants were examined for the evaluation of breathing type, malocclusion, dental anomalies, oral hygiene and dental caries. The parents/caregivers answered a structured questionnaire addressing the individual/behavioral characteristics and medical/dental history of the participants. Statistical analysis involved the chi-square test and multiple logistic regression analysis for the dependent variable (dental caries) (α = 5%). This study received approval from the Human Research Ethics Committee of the Universidade Federal de Minas Gerais. Results The mean age of the individuals was 10.34 ± 6.55 years (median: 9.50 years). Individuals with inadequate oral hygiene were 4.70–fold more likely to have dental caries (95% CI: 2.13–10.40) and those with the rare genetic diseases (MPS/OI) were 2.92-fold more likely to have dental caries (95% CI: 1.38–6.17). Conclusion Individuals with inadequate oral hygiene and those with MPS and OI had a greater chance of belonging to the group with dental caries. Based on the present findings, individuals with the rare genetic diseases may be considered vulnerable to caries.
