RESUMO
Objective To describe the smile characteristics of patients entering the finishing phase of orthodontic treatment. Methods This observational study involved a non-probabilistic sample of 48 patients. Clinical records served as the basis for determining the type of treatment (with or without extractions). Photographs were analyzed to obtain smile variables. Dental casts and panoramic radiographs were evaluated to ascertain the cast-radiograph evaluation (CRE) index. Univariate and bivariate analyses were conducted at a significance level of 0.05. Results The study evaluated 24 men and 24 women, with an average age of 20.10 ± 6.78 years. Fifty percent of the patients did not undergo extractions, and the average CRE index for the sample was 34.83 ± 9.01. Regarding the smile, a medium smile line was prevalent in 66.7% of cases, and a non-consonant smile arc was observed in 58.3%. Significant differences in the smile arc were found between patients with and without extractions (p=0.019). Right and left buccal corridors measured 2.52 mm ± 1.52 and 2.43 mm ± 1.37, respectively. The upper dental midline deviated by 0.80 ± 0.91 mm and had an angulation of 1.65 ± 2.05º. Both variables showed significant differences between Class I and Class II patients (p=0.020; p=0.027). Symmetrical smiles were also observed (1.05 ± 0.17). Conclusions Based on our findings, clinicians should focus on the smile arc in patients who have not undergone extractions and on the midline inclination in Class II patients. These appear to be the most common areas for improvement in patients who are in the finishing phase of treatment. Additionally, considerable variability exists in the smile characteristics of patients still undergoing orthodontic treatment, leaving room for further enhancement of results.
RESUMO
BACKGROUND: This study evaluated the association between knowledge and management of ventilation and air-conditioning systems (VAC) to avoid the spread of the SARS-CoV-2 virus in health facilities by dentists and demographic variables. MATERIAL AND METHODS: A cross-sectional digital media survey was administered to dentists as part of global research. The core questionnaire was used including four additional questions on VAC (Q1: knowledge, Q2: work settings, Q3: temperature, and Q4: maintenance). A descriptive analysis was conducted for sociodemographic and VAC variables, and bivariate analysis was carried out using different tests. RESULTS: 5370 dentists answered the survey (median age of 45 years; 72.22% women). About half of the respondents said that they knew about the guidelines issued for the management of air conditioners (AC) during the pandemic, and 16.77% have made modifications to their VAC systems during this period. The most frequent AC temperature range used in the dentists' offices during the pandemic was 18°C to 20°C. As age increased, self-reported knowledge about VAC guidelines expanded. Remote and rural regions were perceived to have less knowledge of the guidelines. CONCLUSIONS: Although perceptions of knowledge about VAC systems during the COVID-19 pandemic was high, the temperature in dental offices was colder than that recommended. Greater disclosure of VAC management practices and adherence to VAC management guidelines are required. Key words:Air conditioning, dentistry, coronavirus.
RESUMO
ABSTRACT Introduction: this study aimed to evaluate practice modification, use of personal protective equipment, biosafety measures, impact on career plans, prevalence of contagion, and risk perception of dentists during the COVID-19 pandemic 19 in Colombia. Methods: this is a cross-sectional study. Following ethical approval, an anonymous digital survey was conducted with dentists in Colombia. The questions comprised four domains: 1) sociodemographic, 2) employment and impact on career plans, 3) protocol compliance and biosafety, and 4) knowledge, risk, and contagion risk perception. A descriptive analysis of the data is presented. Results: 5,370 general and specialist dentists participated in the study (women: 3878; average age: 45 years). 41.94% were general dentists. Compliance with safety guidelines and use of personal protective equipment (PPE) was greater than 99%. The majority of dentists (91.29%) canceled their clinical activities during quarantine and have thought about reducing their working hours (77.96%). The perception of COVID-19 risk contagion was high (95.91% reported that contagion is likely/highly likely), although COVID-19 contagion self-report was low (0.61%). Conclusion: COVID-19 pandemic has strongly impacted the practice of dentistry in Colombia, leading to changes in clinical activities and career prospects. Biosafety measures compliance and PPE use was high. Although the contagion risk perception was high, self-reported contagion was very low.
Resumen Introducción: este estudio tuvo como objetivo evaluar la modificación de la práctica, uso de elementos de protección personal, protocolos de bioseguridad, afectación en los planes de carrera, prevalencia de contagio y percepción de riesgo de los odontólogos durante la pandemia de COVID-19 en Colombia. Métodos: tras obtener la aprobación ética, se aplicó una encuesta digital anónima a los odontólogos de Colombia. Las preguntas incluyeron cuatro dominios: 1) sociodemográficos, 2) laborales y afectación en los planes de carrera, 3) Seguimiento a protocolos y bioseguridad y 4) Conocimientos, riesgo y percepción de riesgo de contagio. Se presenta un análisis descriptivo de los datos. Resultados: 5370 odontólogos generales y especialistas participaron del estudio (mujeres: 3878; mediana de edad: 45 años). El 41,94% fueron odontólogos generales. La adherencia a protocolos de seguridad y el uso de elementos de protección personal (EPP) fue mayor al 99%. La mayoría de odontólogos (91,29%) suspendió sus actividades clínicas durante la cuarentena y ha pensado en disminuir sus horas de trabajo (77,96%). La percepción de riesgo de contagio de la COVID-19 fue alta (95,91% refirió que es muy probable/probable el contagio), aunque el auto-reporte de contagio por COVID-19 fue bajo (0,61%). Conclusión: la pandemia de la COVID-19 ha impactado fuertemente la práctica de la odontología en Colombia, generando cambios en las actividades clínicas y en las perspectivas de carrera. El seguimiento de protocolos de bioseguridad y de uso de EPP fue alto. Aunque la percepción de riesgo de contagio fue alta, el contagio auto-reportado fue muy bajo.

OBJECTIVE: To establish the association between malocclusion severity and orthodontic case complexity as assessed by the Dental Aesthetic Index (DAI) and the American Board of Orthodontics Discrepancy Index (ABO-DI), respectively. DESIGN: Cross-sectional study. SETTING: Pre-treatment dental casts and radiographs from 500 individuals (294 women and 206 men; mean age = 26.06 ± 11.58 years) were randomly selected from the orthodontics department of a private university. METHODS: Malocclusion severity was assessed using DAI and case complexity was evaluated with ABO-DI. Three previously calibrated operators performed the measurements. Spearman's correlation analysis, Mann-Whitney U test, Kruskal-Wallis test and a linear generalised model were used for statistical evaluation (P < 0.05 was considered significant). RESULTS: Although the correlation (r = 0.45; P < 0.0001) between malocclusion severity and case complexity was moderate, strong evidence of an association (P < 0.001) between dichotomised DAI and ABO-DI total scores was observed. The linear generalised model showed that for each point of increase in DAI score, the ABO-DI score increased an average of 0.3624 points (P < 0.0001). CONCLUSION: An association between malocclusion severity and case complexity is suggested. A linear generalised model could be used to predict the complexity of the case from the malocclusion severity (DAI score).
