BackgroundTraumatic dental injury (TDI) during childhood may negatively impact the quality of life of children.ObjectiveTo describe the association of oral health-related quality of life (OHRQoL) and domains (oral symptons, functional limitation, emotional- and social-well-being) of children with individual and contextual variables.MethodsA cross-sectional study was performed using a representative sample of 1,201 schoolchildren, 8–10 years-old, from public and private schools of Belo Horizonte, Brazil. The CPQ8–10 was used to assess OHRQoL, dichotomized in low and high impact. Sociodemographic information was collected through questionnaires to parents. Children were examined at schools, using the Andreasen criteria. Individual variables were gender, age, number of residents in home, parents/caregivers’ level of education, family income, and TDI (dichotomized into without trauma/mild trauma and severe trauma). Dental caries and malocclusion were considered co-variables. Contextual variables were the Social Vulnerability Index and type of school. Ethical approval and consent forms were obtained. Data were analyzed using SPSS for Windows 19.0 and HLM 6.06, including frequency distribution, chi-squared test and multilevel approach (p < 0.05).ResultsThe prevalence of a negative impact on OHRQoL in children with severe trauma was 55.9%. The TDI negatively impacted emotional and social domains of OHRQoL. A multilevel analysis revealed a significant difference in OHRQoL according to the type of school and showed that 16% of the total variance was due to contextual characteristics (p < 0.001; ICC = 0.16). The negative impact on OHRQoL was higher in girls (p = 0.009), younger children (p = 0.023), with severe TDI (p = 0.014), those from public schools (p = 0.017) and whose parents had a lower education level (p = 0.001).ConclusionSevere trauma impacts OHRQoL on emotional and social domains. Contextual dimensions add information to individual variability to explain higher impact, emphasizing socioeconomic inequalities.

A highly cited paper is seen as a landmark in any field and can influence both research and clinical practice. This study aimed to quali-quantitatively analyze the 100 most-cited papers in Cariology. A search strategy was first determined using specific keywords related to the field. A comprehensive search was then conducted in the Thompson Reuters Web of Science citation indexing database up to April 2019. Papers focused on any aspect of Cariology were included. A panel of 4 researchers conducted the selection of papers and extracted data on the number of citations, title, authors, country, year, journals, study design, and topic of interest. Scopus and Google Scholar were also searched to compare the number of citations. The VOSviewer software was used to generate bibliometric networks. The number of citations among the top 100 most-cited papers ranged from 168 to 1,961 with a mean of 292,66. Three papers had more than 1,000 citations. The <i>Journal of Dental Research</i> (20%) and <i>Caries Research</i> (17%) had more top papers. The oldest and the most recent papers were published in 1960 and 2015. Literature reviews (35%) and laboratorial studies (31%) were the most common study designs. The countries with the highest number of most-cited papers were the USA (40%), Sweden (10%), and Japan (9%). The most studied fields of interest were etiology/pathogenesis (41%) and prevention (20%). VOSviewer maps revealed collaborative networks between countries and organizations. The top 100 most-cited papers in Cariology were published mainly by European and Anglo-Saxon American authors and were composed mainly of literature reviews with etiology/pathogenesis as the most frequent topic of interest.

The aim of the present study was to compare self-reported dental fear among dental students and patients at a School of Dentistry in Belo Horizonte, Brazil. Eighty students ranging in age from 20 to 29 years and 80 patients ranging in age from 18 to 65 years participated in the study. A self-administered pre-tested questionnaire consisting of 13 items was used for data acquisition. The city of Belo Horizonte Social Vulnerability Index (SVI) was employed for socioeconomic classification. The chi-square test and binary and multinomial logistic regression were employed in the statistical analysis, with the significance level set at 0.05. The majority of dental students (76.5%) sought the dentist for the first time for a routine exam, while patients (77.3%) mostly sought a dentist for the treatment of dental pain. Dental fear was more prevalent among the patients (72.5%) than the students (27.5%). A total of 47.1% of the students and 52.9% of the patients reported having had negative dental experiences in childhood. The logistic model revealed an association between dental fear and a pain-related experience (OR: 1.8; 95%CI: 1.3–2.6). Patients were more prone to dental fear (OR: 2.2; 95%CI: 1.0–5.0). Although at different percentages, both students and patients experienced dental fear. Current patient with previous experience of dental pain had more dental fear.

The aim of this study was to assess the prevalence and discriminate the associated factors between enamel fractures and other trauma/trauma sequelae in 8 to 10-year-old Brazilian schoolchildren. A representative sample of 1,201 children from public and private schools were enrolled in this cross-sectional study. Questionnaires about sociodemographic characteristics were answered by parents. The outcome variable (traumatic dental injury, TDI) was multi-categorized. Independent individual variables were sex, age, number of residents in household, parents/caregivers' level of education, family income, dental caries, and overjet. Type of school was considered an independent contextual variable. Multilevel analysis, bivariate, and multivariate multinomial logistic regression models were performed. The prevalence of TDI was 14.0% (2.8% with other trauma/trauma sequelae). The multilevel analysis revealed no significant difference between the type of school and TDI. The multinomial logistic regression showed that boys (OR = 2.3; 95%CI: 1.1-4.8), older children (OR = 1.8; 95%CI: 1.1-3.0) and individuals with an overjet > 3 mm (OR = 2.5; 95%CI: 1.0-6.2) were more likely to present other trauma/trauma sequelae. Enamel fracture was not significantly associated with any variables. The prevalence of TDI in 8 to 10-year-old schoolchildren was 14% but only 2.8% of other trauma/trauma sequelae. Differences regarding the associated factors of TDI involving enamel fracture or other trauma/trauma sequelae were detected, suggesting that the different TDI classification cannot be evaluated as a single category.

Studies evaluating the factors associated with under reporting and with the recognition and reporting of child physical abuse are scarce and highly necessary. This study aimed to assess the prevalence of recognition and reporting of child physical abuse (CPA) by Brazilian dentistsin primary care and associated factors. A cross-sectional study was carried out with a representative sample of dentistsfrom the Family Health Strategy in Belo Horizonte. A self-administered questionnaire validated to Brazilian Portuguesewas used for data collection. Statistical analysis included univariate and multiple analyses through Poisson regression. A total of 181dentists participated in the study. Among them, 73 (40.3%) had already recognized some cases of CPA, but only 11 (6.1%) ended up reporting. Dentists with six to 19 years of experience as a municipal worker presented 2.38 times [PR = 2.38 (95%CI: 1.29-4.41)] more probability to recognize cases of CPA than the ones with less than six years. Having a graduate degree with a major in childcare [PR = 4.50 (95%CI: 1.08-18.68)] was associated with a larger number of reports. The employment duration as municipal worker was positively associated with the recognition of CPA cases and the prevalence of reporting was low.

ABSTRACTThis study aims at evaluating the use of conceptual maps in the integrated primary clinical care disciplines I, II, III, IV, V and pediatric dentistry disciplines I and II from the undergraduate course of the dental school of the federal university of minas gerais, considering students' perception. The disciplines have experimentally introduced the use of conceptual maps as a teaching strategy during the first semester of 2011 with different approaches, considering the specificity of each topic. In the end of the semester questionnaires for the evaluation of the use of the conceptual maps were distributed among the students enrolled in the mentioned disciplines. Among the 196 students who answered the questionnaires, 69.4% positively evaluated the activity. It should be mentioned that 73% of the students said they were satisfied with the use of conceptual maps in reporting clinical cases. Moreover, the students highlighted the use of conceptual maps in summarizing the topics under study, understanding and articulating knowledge and providing integral care for patients. Such results point towards the need for improvement of the use of conceptual maps, while they should remain as a teaching strategy for the next semesters.

Background: The aim of this study was to elaborate a randomized clinical trial protocol to evaluate the effectiveness of class I restorations in resin-modified glass ionomer cement (RMGIC) and bulk-fill resin in primary molars with untreated early childhood caries in toddlers. Material and Methods: A total of 59 toddlers up to 36 months old with at least two primary molar teeth with untreated dental caries of single surface on different sides of the mouth will be selected at the Pediatric Dentistry Clinics of the Faculty of Dentistry at Federal University of Minas Gerais (UFMG), Brazil. Teeth with untreated dental caries in the left and right sides of each patient’s mouth will be randomly distributed into 2 groups: Group 1 (Control): encapsulated RMGIC restoration with Riva light cure (SDI, Florida, USA) and Group 2 (Test): Filtek bulk-fill composite resin restoration (3M/ESPE, St. Paul, USA) with universal single bond adhesive system (3M/ESPE, St. Paul, USA). A single trained dentist will perform all restorative procedures. The restorations will be evaluated after 1, 6, 12, 18 and 24 months by two trained and calibrated examiners. Cost-efficacy analysis will be carried out. Kaplan-Meier survival analysis, Log-rank test, Cox regression, Poisson regression analysis, Mann-Whitney test or Kruskal-Wallis will be performed to analyze data. Conclusion: The protocol will make it possible to determine the most efficacy material for the restoration of cavities in cavities in primary molars of toddlers.
