Objective: The aim of this work was to investigate what the orthodontist’s difficulties are, analyzing whether the adopted procedures are able to satisfy the complaints of individuals, who already concluded orthodontic therapy, according to the determinations of the civil code and the Costumer’s Defense Code, as well as the relationship between patient and professional. Methods: A questionnaire was sent by postal service to all the odonthology specialists inrolled in the CRO/RJ amounting to 990 professionals.Results: The percentual analysis of the analysis showed that 96.9% of them adopt some pattern of kind of contract. The majority (65.8%)regards the orthodontist’s Civil Responsibility as a result. In case of reincident postrentation, 87.2% of the professionals inform the individual that it’s possible and also propose them orthodontic re-treatment. Concerning the conduct adopted by the orthodontist towards the individual’s dissatisfaction, 76.5%, anyhow, try to avoid a lawsuit. Conclusion: Some professionals may be subject to future court problems, there was wide divergence between professionals in relation to the time of filing of the orthodontic documentation and there was a relative same opinion of professionals in making an oversight of the patient in the period post-restraint

Knoop hardness of enamel and shear bond strength of brackets bonded with composite resin with and without fluoride

OBJECTIVE: The aim of this study was to evaluate the Knoop hardness of enamel, shear bond strength and failure pattern (adhesive, bracket/resin interface or mixed) after bonding and debonding brackets, using resin composite with fluoride (Ortho Lite Cure, Ortho Source®) and without fluoride (Orthobond, Morelli®). METHODS: Fragments (6 mm x 6 mm) of 40 bovine incisor crowns were embedded in acrylic self-polymerizing resin. The Knoop hardness measurements were performed before and after bonding metal brackets. The specimens were divided into two groups, according to composite resin: with fluoride (Ortho Lite Cure, Ortho Source®) and without fluoride (Orthobond, Morelli®). After bonding, the specimens were submitted to demineralization and remineralization cycling for 14 days. Shear bond strength testing was performed in a universal test machine (EMIC), at 5 mm/min crosshead speed. RESULTS: There was no significant difference in shear bond strength between Groups I and II. After demineralization and remineralization procedures (DE/RE), the specimens bonded with Ortho Lite Cure showed higher Knoop hardness than Orthobond. For both groups there was predominance of failure at bracket/resin interface. CONCLUSION: specimens bonded with fluoride resin composite showed higher microhardness after DE/RE cycling than those bonded with resin composite without fluoride, although no difference in shear bond strength was found

What Factors are Associated with Health-Related Quality of Life in Mixed Dentition Children?

Objective: To associate the OHRQoL and HRQoL in mixed dentition children with the influence on age range, socioeconomic and clinical variables. Material and Methods: A cross-sectional study was carried out with 1,240 children between 6 and 12 years of age. HRQoL was assessed by the Quality of Life Assessment Scale, considered an outcome variable. OHRQoL was determined using specific questionnaires related to the age group: Oral Health Impact Scale in Early Childhood, Child Perceptions Questionnaire for 8 to 10 years, and 11 to 12 years. Dental caries and malocclusion were diagnosed. The socioeconomic class was evaluated. A multiple negative binomial regression analysis was used to test the relationship between HRQoL, OHRQoL scores and socioeconomic and clinical variables. Correlation analyses were performed between the total HRQoL and OHRQoL, with a significance level of 5%. Results: The HRQoL is inversely related to the impact of OHRQoL (p<0.05), modulated by the age group. There was a significant weak negative correlation between the HRQoL scores and the impact of OHRQoL (p<0.05). Conclusion:The OHRQoL impacts the HRQoL, modulated by the age group and with minor influence from socioeconomic and clinical variables

A Multivariate Analysis of the Psychosocial Impact of Malocclusion and Self-Esteem in Adolescents

Objective: To evaluate the psychosocial impact of malocclusion and self-esteem in adolescents in the Amazon region. Material and Methods: A cross-sectional study was carried out with 212 adolescents with 12-year-old enrolled in all public schools in the Boca do Acre (Amazonas, Brazil). Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) assessed the psychosocial impact of malocclusion. The self-perception of the need for orthodontic treatment was evaluated by the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) and Global Negative Self-evaluation (GSE), the adolescent's self-esteem. The malocclusion was clinically evaluated by the Dental Aesthetic Index (DAI). The variables with p<0.20 in the individual analyses were tested in multiple logistic regression models, and those with p<0.10 remained in the model. The adjusted odds ratio (OR) was estimated with a 95% confidence interval (CI). Results: Adolescents with low self-esteem were 2.20 (95% CI: 1.23-3.93) times more likely to have a more significant impact on dental aesthetics (p<0.05). When verified by domains, the adolescents with low self-esteem had 2.33 (95% CI: 1.31-4.17) and 1.93 (95% CI: 1.09-3.42) times more likely to impact the psychological and social domains of the PIDAQ, respectively. Conclusion: Self-esteem influenced adolescents' perception of dental aesthetics in the domains related to psychological and social impact

Surface properties of composite resins with and without fluorides for bracket bonding / Propriedades de superfície de resinas compostas com e sem fluoretos para colagem de suportes

The aim of this study was to evaluate the surface properties of orthodontic resins with and without fluoride. Forty disks, measuring 2 mm thick by 6 mm in diameter, were made of 4 bracket-bonding composite resins (n=10): Transbond Plus Color Change-3M/Unitek (TPCC); Transbond XT- 3M/Unitek (TXT), Orthocem -FGM (OC); Orthocem UV Trace-FGM (OCUV). The discs were photoactivated for 40 seconds with irradiance of 450 mW/cm2 and manually polished in sequence by silicon carbide sandpapers with 1200 and 2000 grain size and finished with diamond paste and felt disc. The surface microhardness analysis was performed using a Shimadzu Micro Hardness Tester HMV-2,000 (Shimadzu Corporation, Kyoto, Japan) with a load of 50 gF and a 5 second penetration time. Surface roughness readings were taken using a Surf Corder Roughness Meter (SE 1700- Kosaka, Lisboa-Portugal). For data analysis, ANOVA (one-way) was used, followed by Tukey's post-test (?=0.05). The microhardness results showed a difference (p?0.05) in the means of the orthodontic resins between TPCC and TXT with the other groups. After the surface roughness analysis, the averages showed that TPCC resin showed higher roughness compared to OC and OCUV (p?0.05), and there was no statistical difference with TXT. It was concluded that statistically the composite resins with fluoride showed significant difference regarding hardness and roughness

Knowledge of undergraduate students of the course in dentistry about the transmission of covid-19 in dental offices / Conhecimento dos estudantes de graduação do curso de odontologia sobre a transmissão da covid-19 em consultórios odontológicos

The aim of this study was to evaluate the knowledge of dental students about the transmission of coronavirus in dental offices, and the biosafety measures that must be adopted to prevent its dissemination. An online questionnaire with 18 questions was applied to  the students to collect the information. The sample was composed of 126 students of the dentistry course of public and private universities who had previous contact with clinical practice. The results revealed that 68.3% of the undergraduates were aware that dentists were among the health professionals who were at most risk for contamination, and 93.7% of them said that the procedures that generated aerosol in the dental office were those that led to the highest chances of transmission of  COVID-19. The responses also showed the awareness of students relative to the need to use all the items of personal protective equipment (PPE), in which 90% of the participants considered masks, caps, gloves, facial protectors, aprons, and protective goggles to be essential for preventing propagation of the virus. When asked about hand hygiene, 92.1% of the students considered soap and water the best option. Based on assessment of patients’ history (recent travels, chronic diseases and present health status), 87% reported that it was also important to obtain these items of  before attending a patient. It was concluded that the undergraduates had knowledge about the transmission and biosafety methods in the dental office, related to COVID-19, which would contribute to the safety of clinical attendance in the universities

Correlation between general quality of life and oral health related quality in the mixed dentition

Abstract The aim of this study was to evaluate the convergence between the domains of the Autoquestionnaire Qualité de Vie Enfant image (AUQUEI) and the Child Perceptions Questionnaire (CPQ8-10) in the mixed dentition. A sample of 676 children aged 8 to 10 years responded to the health-related quality of life (HRQoL) and oral health-related quality of life (OHRQoL) questionnaires using the AUQUEI and the CPQ8-10, respectively. Clinical (dental caries and malocclusion) and socioeconomic variables were assessed. The validity of convergence between scores (total and per domain) of the two instruments was assessed by Spearman correlation analysis, considering that non-zero coefficient values represented a correlation between scores. The median was calculated to compare the scores of each questionnaire relative to the variables, and the nonparametric Mann-Whitney test was applied to determine statistically significant differences between the categories. A weak significant correlation (between 0.30 and 0.50) was observed between the domains and the total scores of instruments (p 0.05). Participants with a lower family income had worse HRQoL (p < 0.05), and those with caries and malocclusion experience had worse OHRQoL (p < 0.05). In conclusion, the AUQUEI and CPQ8-10 instruments showed a weak correlation. Income and clinical variables had a negative impact on the AUQUEI and CPQ8-10, respectively

On-line Searches for Terms Related to Hand Hygiene During the COVID-19 Pandemic Worldwide

Objective: To analyze the difference in the on-line searches for terms related to hand hygiene during the COVID-19 pandemic in developed and middle-income countries. Material and Methods: The cross-sectional study analyzed the digital data through the Google Trends website to obtain the variation of the relative search volume (RSV) through the terms "alcohol gel" and "handwashing." According to socio-economic development, the countries were divided into two groups: countries from different continents and hemispheres, with more than 15 million inhabitants, with more than 50% of the population with access to the Internet network and over 1,000 confirmed cases of infected with COVID-19. The paired t-test was applied to compare the means. The significance value adopted was p&lt;0.010. Results: The searches related to the term "hand washing" were more significant when compared to the term "alcohol gel," and the term "alcohol gel" presented a higher average volume of research in developed countries (p&lt;0.010). The developed countries had a higher average relative volume of research than middle-income countries (p&lt;0.010). Developed countries sought more for the term "alcohol gel," and the term "hand washing" showed no difference in the volume of research about the country's socio-economic aspect. Conclusion: Developed countries have a higher volume of search for hand hygiene terms. The middle-income countries must create proposals for raising awareness outside the on-line environment so that this information reaches the entire population during the pandemic
