Utilização de serviços odontológicos por crianças de 0 a 5 anos de idade no Município de Canela, Rio Grande do Sul, Brasil

The aim of this study was to assess the use of dental services and age at first dental visit in preschool children in Canela, Rio Grande do Sul State, Brazil. A representative sample of under-five children was surveyed on National Childrens Vaccination Day. Childrens parents completed questionnaires containing socio-demographic data and age at first dental visit. Data were analyzed using multiple logistic regression. 192 children were examined. 13.3% of the sample had already visited the dentist at least once, but only 4.3% had their first dental visit by one year of age. The number of children who had already visited a dentist increased with age. Girls showed higher odds of having visited a dentist (OR = 1.46; 95%CI: 1.01-2.1). Public health strategies are needed to determine the effectiveness of health promotion and improve the use of dental services by preschool children.

Exploring factors associated with traumatic dental injuries in preschool children: a Poisson regression analysis.

OBJECTIVE This cross-sectional study aimed to investigate the factors associated with dental trauma in preschool children using Poisson regression analysis with robust variance. SUBJECTS AND METHODS The study population comprised 888 children aged 3- to 5-year-old attending public nurseries in Canoas, southern Brazil. Questionnaires assessing information related to the independent variables (age, gender, race, mothers educational level and family income) were completed by the parents. Clinical examinations were carried out by five trained examiners in order to assess traumatic dental injuries (TDI) according to Andreasens classification. One of the five examiners was calibrated to assess orthodontic characteristics (open bite and overjet). Multivariable Poisson regression analysis with robust variance was used to determine the factors associated with dental trauma as well as the strengths of association. Traditional logistic regression was also performed in order to compare the estimates obtained by both methods of statistical analysis. RESULTS 36.4% (323/888) of the children suffered dental trauma and there was no difference in prevalence rates from 3 to 5 years of age. Poisson regression analysis showed that the probability of the outcome was almost 30% higher for children whose mothers had more than 8 years of education (Prevalence Ratio = 1.28; 95% CI = 1.03-1.60) and 63% higher for children with an overjet greater than 2 mm (Prevalence Ratio = 1.63; 95% CI = 1.31-2.03). Odds ratios clearly overestimated the size of the effect when compared with prevalence ratios. CONCLUSIONS These findings indicate the need for preventive orientation regarding TDI, in order to educate parents and caregivers about supervising infants, particularly those with increased overjet and whose mothers have a higher level of education. Poisson regression with robust variance represents a better alternative than logistic regression to estimate the risk of dental trauma in preschool children.

Dental anomalies and associated factors in 2- to 5-year-old Brazilian children

BACKGROUND Dental anomalies in primary teeth may lead to functional and aesthetic disorders, and their recognition contributes to early diagnosis and long-term treatment planning. OBJECTIVE This study investigated the prevalence of dental anomalies in primary dentition and associated factors in Brazilian preschoolers. METHODS The study population of this cross-sectional study comprised 1260 2- to 5-year-old children from public nurseries in Canoas, southern Brazil. Dental anomalies were recorded by five trained examiners according to Kreiborg criteria; classification included double teeth, hypodontia, supernumerary, and microdontia. RESULTS Dental anomalies as a group were found in 2.5% of children, although no significant difference occurred between genders and races. All the anomalies were observed in the anterior region, with no significant differences between the arches. However, supernumerary teeth were significantly more frequent among the non-white racial group (Fisher; P = 0.025) and double teeth on the lower arch (McNemar; P = 0.020). Individual anomaly frequencies were: double teeth, 1.3%; hypodontia, 0.6%; supernumerary, 0.3%; and microdontia, 0.3%. CONCLUSIONS The frequency of primary dentition anomalies as a group was greater than that reported in other populations; the findings of this study provide a clear vision of the distribution of this oral condition and may well contribute to early detection and treatment planning.

Association between occlusal anomalies and dental caries in 3‐ to 5 year‐old Brazilian children

Objective To investigate the association between certain occlusal anomalies and the occurrence and severity of dental caries in Brazilian preschool children. Design Cross‐sectional study. Setting Twenty‐eight public nursery schools in Canoas, southern Brazil. Subjects and methods The study population comprised 890 three‐ to five‐year‐old children. Five trained and calibrated observers examined children for determination of decayed, missing and filled tooth (dmft) index (World Health Organization criteria including white spots) and orthodontic variables. Outcome measures Caries severity (dmft) and caries occurrence (dmft⩾1). Statistical analysis Multivariable analysis was performed using Poisson regression with robust variance in order to determine the occlusal anomalies which represent risk factors for the occurrence of the binary outcome. Results Caries severity was significantly higher among children without spacing in the maxillary anterior teeth (P = 0·001) and mandibular anterior teeth (P = 0·003) and among children without accentuated overjet (P = 0·023). The multivariable analysis demonstrated that children without spacing in maxillary anterior teeth had an increased risk of dental caries (prevalence ratio = 1·43; 95% CI, 1·05–1·93). Open bite, accentuated overjet and posterior cross‐bite were not associated with this outcome in the final model. Conclusions Absence of spacing in the maxillary labial segment represents a risk factor for dental caries in preschool children.

Gains in children's dental health differ by socioeconomic position: evidence of widening inequalities in southern Brazil

UNLABELLED Oral health inequalities are the measures by which equity in oral health is tracked. Despite widespread improvement in childrens dental health globally, substantial socio-economic disparities persist and may be worsening. OBJECTIVES Quantify 10-year changes in child caries occurrence by socio-economic position in a Southern Brazilian city and compare oral health inequalities over time. METHODS Representative surveys of dental caries in children (age <6 years) in Canoas, Brazil, were conducted in 2000 and 2010 following standardized methods. For each survey year, we calculated disparities by socio-economic position (maternal education and family income) in age- and sex-standardized caries occurrence (prevalence: dmft > 0; severity: mean dmft) using absolute measures (difference and Slope Index of Inequality) and relative measures (ratio and Relative Index of Inequality). RESULTS Comparing 2010 to 2000, caries occurrence was lower in all socio-economic strata. However, reductions were more pronounced among socio-economically advantaged groups, yielding no improvement in childrens oral health disparities. Some disparity indicators were consistent with increasing inequality. CONCLUSIONS Overall, dental caries levels among children in Canoas improved, but inequalities in disease distribution endured. Concerted public health efforts targeting socio-economically disadvantaged groups are needed to achieve greater equity in childrens oral health.

Pre-eruptive Intracoronal Radiolucency in First Permanent Molar

Pre-eruptive intracoronal radiolucency (PECR) is characterized by the existence of a radiographic radiolucent area inside the coronal dentin prior to dental eruption. It is a rare clinical entity of unknown etiology, usually asymptomatic and diagnosed through routine radiographs. The aim of this article is to report the treatment of a PECR in an 8-year-old girl. Surgical procedure to expose the crown was conducted; upon tooth eruption, the radiolucent lesion was accessed and the tooth was restored. The case has an 18-month follow-up and emphasis on aspects linked to diagnosis and clinical approach was discussed. How to cite this article: Ilha MC, Kramer PF, Ferreira SH, Ruschel HC.
