Artificial intelligence: ChatGPT as a disruptive didactic strategy in dental education.

PURPOSE: To evaluate the influence of ChatGPT on academic tasks performed by undergraduate dental students. METHOD: Fifty-five participants completed scientific writing assignments. First, ChatGPT was utilized; subsequently, a conventional method involving the search of scientific articles was employed. Each task was preceded by a 30-min training session. The assignments were reviewed by professors, and an anonymous questionnaire was administered to the students regarding the usefulness of ChatGPT. Data were analyzed by Mann-Whitney U-test. RESULTS: Final scores and scores for the criteria of utilization of evidence, evaluation of arguments, and generation of alternatives achieved higher values through the traditional method than with ChatGPT (p = 0.019, 0.042, 0.017, and <0.001, respectively). No differences were found between the two methods for the remaining criteria (p > 0.05). A total of 64.29% of the students found ChatGPT useful, 33.33% found it very useful, and 3.38% not very useful. Regarding its application in further academic activities, 54.76% considered it useful, 40.48% found it very useful, and 4.76% not very useful. A total of 61.90% of the participants indicated that ChatGPT contributed to over 25% of their productivity, while 11.9% perceived it contributed to less than 15%. Concerning the relevance of having known ChatGPT for academic tasks, 50% found it opportune, 45.24% found it very opportune, 2.38% were unsure, and the same percentage thought it is inopportune. All students provided positive feedback. CONCLUSION: Dental students highly valued the experience of using ChatGPT for academic tasks. Nonetheless, the traditional method of searching for scientific articles yield higher scores.

Depth and proximity of third molars to the inferior alveolar canal in panoramic radiographs of a Latin American population

Introduction: extraction of lower third molars involve the possible occurrence of complications such as injury of the content of the Inferior Alveolar Canal. Methods: a cross-sectional study was conducted with a sample of 6488 lower molar records of digital panoramic radiographs of patients from 6 Latin American countries from 2010-2015. The variables studied were the depth of lower third molar according to the Pell and Gregory classification, and the proximity of a third molar to the Inferior Alveolar Canal that was evaluated according to the proposed classification, based on a modification of the Langlais et al classification.20 Descriptive and bivariate statistical analyses were performed. Results: in terms of the proximity, the highest frequency was Intact with 27.45%(n=1781). Regarding the depth of the lower third molar, the most frequent were the Position B with 46.90%(n=3043) and Position A with 46.75%(n=3033). The proximity and depth of the lower third molar had statistical difference according to age(p<0.01) and sex (p<0.001). The overall proximity of the lower third molar to the Inferior alveolar canal, according to depth was 37.52%(n=1766) in Position A, in Position B it was 54.51%(n=2566) and Position C was 7.97%(n=375) and had association between variables(p<0.001). Conclusions: taking into consideration the modified classification of Langlais et al.20, lower third molars are close to the Inferior Alveolar Canal, and according to the Pell and Gregory classification for the depth, the most frequent positions are A and B. In addition, proximity and depth were associated with each other, and with the co-variables country, age, and sex.

Time elapsed since peruvian children's last dental care and head of household educational attainment: findings from a national database.

BACKGROUND: It has been documented that the parents' highest level of education has an impact on their children's access to oral health services and the frequency of their use.This study aimed to determine the association between time elapsed since peruvian children's last dental care and head of household educational attainment. METHODS: Cross-sectional study using a database of children aged 0 to 11 years, with a final sample of 8012 participants. The dependent variable in this study was the time elapsed since last dental care and the independent variable was the head of household educational attainment. Other covariates considered were natural region, area of residence, place of residence, altitude, wealth index, health insurance coverage, sex and age. Descriptive, bivariate and multivariate statistical analyses were applied. RESULTS: Time elapsed since last dental care in the year 2021 was 5.68 years (SD = 5.25). A hierarchical multiple linear regression analysis was performed, analyzing the variables dimensions by separate and joint models. When head of household educational attainment was analyzed, there was no statistical significance (p = 0.262); however, other models did (p < 0.05). Model 4, which addresses all dimensions, was significant (p < 0.001) with an R2% of 0.011 and constant equal to 5.788; it showed significance with place of dental care, health insurance, altitude and age. CONCLUSIONS: No association was found between head of household educational attainment and time elapsed since last dental care; however, the latter was associated with place of care, health insurance coverage, altitude and age in Peruvian children.

The Objective was identify the relevant clinical factors in the diagnosis of a posterior bite collapse. Is a systematic review based on reports and case series. Was considered as dimensions: dental occlusion, muscle tissue, temporomandibular joint, periodontal tissue and radiographic examination. Of 82 initially selected articles, the review was carried out with 6 articles. The information was ordered describing each one of them, being the publications between 1987 and 2020. We can Conclude that Relevant clinical factors for the correct diagnosis of a posterior bite collapse were identified according to the study dimensions: loss of teeth, alteration of the vertical dimension, periodontitis, deviation in the opening and closing of the TMJ, and bone resorption, as the most predominant according to the diagnostic dimensions.

Impact of the COVID-19 pandemic on the timing of dental care in elderly peruvians.

In Peru, there is low dental service use among older adults, in addition to a social gradient for use. Furthermore, the COVID-19 pandemic triggered complex scenarios characterized by inadequate access to health services, with greater impact on vulnerable population groups such as the elderly. The aim of this study was to determine the impact of the COVID-19 pandemic on the time since last dental care visit among elderly Peruvians. It was a cross-sectional study conducted on a population of 5247 respondents in 2019, and 5066 respondents in 2020. The study considered the answers of people who responded to the question on the last time they had received dental care, extracting a total 4045 subjects for 2019 and 3943 for 2020. The dependent variable was time since last dental care measured in years, while the variables on health, geographic and sociodemographic characteristics were grouped within three dimensions. A descriptive bivariate and multivariateanalysiswasapplied by means of multiple linear regression to analyze the behavior of the variables. Time since the last dental care visit was 7.93 years (SD=8.03) in 2019 and 7.94 years (SD=7.28) in 2020. A hierarchical multiple linear regression analysis was performed, where no variable in the 2019 model was significant; while for 2020, health, geographic, and sociodemographic characteristics variables were significant. In the analysis where the 'year' variable becomes independent, only model 4, which considers all variables, was valid (p=0.018). The variables 'area of residence' and 'wealth index' were also significant. To conclude, the 2020 pandemic year for COVID-19 had no impact on the time since last dental care visit among elderly Peruvians, though factors such as area of residence and wealth index were found to be associated with the time since last dental care visit.

En Perú, los adultos mayores presentan un bajo uso de los servicios odontológicos, además de percibirse una gradiente social para su utilización. Adicionalmente, la pandemia por COVID-19 desencadenó escenarios complejos, caracterizados por un inadecuado acceso a los servicios de salud, que afectó con mayor énfasis a grupos poblacionales vulnerables, como las personas en edades extremas. El objetivo de este estudio fue determinar el impacto de la pandemia por COVID-19 en el tiempo de atención odontológica en adultos mayores peruanos. Estudio transversal con población de 5247 encuestados para el 2019 y 5066 para el 2020. Se consideraron los registros de quienes respondieron a la pregunta sobre el tiempo desde su última atención odontológica, extrayéndose del 2019 un total de 4045 y para 2020, 3943 sujetos. La variable dependiente consistió en el tiempo desde la última atención odontológica medido en años; mientras que dentro de tres dimensiones,seagruparon a lasvariables sobre características de salud, geográficas y sociodemográficas. Se aplicó un análisis descriptivo, bivariado y multivariado, donde el tiempo desde la última atención odontológica en el año 2019 fue de 7.93 años (DE=8.03) y en el 2020 fue de 7.94 años (DE=7.28). Se realizó un análisis de regresión lineal múltiple jerárquica, donde ninguna variable del modelo 2019 fue significativa; mientras que para 2020, las variables características de salud, geográficas y sociodemográficas si lo fueron. Al análisis, donde el año pasa a ser independiente, sólo el modelo 4, que considera todas las variables fue válido (p=0.018); asimismo, el área de residencia e índice de riqueza presentaron significancia estadística. Para concluir, en el año 2020 la pandemia por COVID-19 no impactó en el tiempo de atención odontológica en adultos mayores peruanos, sin embargo, factores como área de residencia e índice de riqueza si presentaron asociación con el tiempo desdelaúltimaatención.

Preventive measures for COVID­19 among dental students and dentists during the mandatory social isolation in Latin America and the Caribbean in 2020.

BACKGROUND: Dentistry is one of the professions that are most exposed to the contagion with coronavirus disease 2019 (COVID­19). However, the prevalence and positivity rates of COVID­19 are low in dentists, indicating that the current measures of infection control may be sufficient to prevent infection in dental settings. OBJECTIVES: The aim of the study was to determine whether the preventive measures for COVID­19 during the mandatory social isolation were followed by dental students and dentists in Latin America and the Caribbean in 2020. MATERIAL AND METHODS: A cross­sectional study was conducted using anonymous virtual surveys in a convenience sample of 2,036 dental students and dentists from 21 Latin American and Caribbean coun­ tries. The variables were the preventive measures for COVID­19 and the sociodemographic characteristics. Descriptive and bivariate analyses were performed. RESULTS: The final sample included 2,036 dental students and dentists. The self­perceived level of know­ ledge about COVID­19 was found to be associated with age, sex, body mass index (BMI), the type of aca­ demic training, having a specialty in the case of professionals, the place of origin, and having met someone with COVID­19 (p < 0.05). The self­perceived level of concern regarding COVID­19 was associated with sex, BMI and having met someone with COVID­19 (p < 0.05). The number of days in the mandatory social isolation was associated with age, the type of academic training, having a specialty, the place of origin, and having met someone with COVID­19 (p < 0.05). The confinement level was associated with age, sex, BMI, the type of academic training, and having met someone with COVID­19 (p < 0.05). Following the preven­ tive measures for COVID­19 was associated with age, the type of academic training, having a specialty, the place of origin, and having met someone with COVID­19 (p < 0.05). The use of face masks, hand washing and social distancing were associated with age, BMI, the type of academic training, the place of origin, and having met someone with COVID­19 (p < 0.05). CONCLUSIONS: Dental students and dentists followed the preventive measures for COVID­19 during the mandatory social isolation period in Latin America and the Caribbean in 2020.

Impact of the COVID-19 pandemic on the timing of dental care in Peruvian children.

BACKGROUND: Due to the high transmissibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), governments adopted preventive measures, such as social distancing and obligatory social immobilization, which negatively affected access to health services, including oral health services. Similarly, dental care restraint arose in this context, with the aim of reducing the possibility of cross-infection caused by aerosols, which notably restricted dental care activity. OBJECTIVES: The aim of the study was to determine the impact of the COVID-19 pandemic on the timing of dental care in Peruvian children. MATERIAL AND METHODS: A cross-sectional study with a population of 42,115 respondents for 2019 and 20,510 for 2020 was conducted. The participants were children aged 0-11 years. The records of those who responded to the question on the time since their last dental care were considered, extracting a total of 22,166 (69.03%) subjects for 2019 and 9,945 (30.97%) subjects for 2020. The dependent variable consisted of the time since the last dental care measured in years; the variables of health, geographic and sociodemographic characteristics were grouped within 3 dimensions. Descriptive bivariate and multivariate analyses were applied by means of multiple linear regression in order to analyze the variables. RESULTS: The time since the last dental care during 2019 was 5.25 ±4.30 years, and it increased to 6.64 ±4.90 years in 2020. Within the multivariate analysis, the dimensions and their variables were ordered hierarchically for 2019 and 2020 separately, and as a whole. Each model was not significant when observed independently (p > 0.05); however, when evaluated as a whole, validity was observed only in model 1 of the year (p = 0.018), with R2 = 2.90, a constant equal to 3.852, the non-standardized regression coefficient (ß) of 1.653, and a 95% confidence interval (CI) of 0.289-3.018. CONCLUSIONS: The 2020 COVID-19 pandemic year had a negative impact on the timing of dental care in Peruvian children, increasing it by 1.39 years as compared to 2019.

Impact of mandatory social isolation measures due to the COVID-19 pandemic on the subjective well-being of Latin American and Caribbean dentists.

BACKGROUND: With the spread of the COVID-19 virus, containment measures such as home confinement were implemented, generating stress, anxiety, depression and aggravation of pre-existing diseases in the population, including dentists, who have also been affected due to the risk involved in practicing their profession. Objective: To determine the impact of mandatory social isolation measures on the subjective well-being of Latin American and Caribbean dentists during the community quarantine due to the COVID-19 pandemic in 2020. MATERIAL AND METHODS: A Cross-sectional study in a sample of 1195 dentists from 21 countries in Latin America and the Caribbean. The main outcome was Subjective Well-Being, evaluated through the World Health Organization Well-Being Index (WHO-5). In addition, sociodemographic characteristics, variables related to the community quarantine due to the COVID-19 pandemic and health variables were considered. A descriptive, bivariate and multivariate (multiple linear regression) analysis was performed to observe the behavior of the variables. RESULTS: A multiple linear regression analysis was performed, where all the variables included within dimensions, were distributed in a single model, observing an R2% of 9.000 (p<0.001), where the R2% change was significant (p<0.001) and a constant of 44.190; likewise, within this model, the variable follow-up of preventive measures against COVID-19 reported an unstandardized regression coefficient (b) of 2. 316 (95%CI:1.133-3.499;p<0.001), the self-perceived level of concern against COVID-19 obtained a (b) of -5.470 (95%CI:-7.509--3.430; p<0.001), the biological sex variable manifested a (b) of -5.417 (95%CI: - 1.157-1.910; p<0.001); finally, the level of economic income during compulsory social isolation presented a (b)=5.354 (CI95%:3.461- 7.247; p<0.001). CONCLUSIONS: An association was found between subjective well-being and variables related to the social impact of the COVID-19 pandemic, such as following preventive measures, concern about the pandemic and economic factors (decrease in income level), in addition to biologic sex. Follow-up strategies are required for these dental professionals, considering that social isolation measures have continued in many of the countries.

Peruvian Children's Access to Oral Health Information during the COVID- 19 Pandemic.

Aim: The aim of this study was to determine the impact of COVID-19 pandemic on access to oral health information of Peruvian children. Materials and Methods: The Demographic and Family Health Survey generates annually a national database of Peruvian children between 0 and 11 years old, which is collected through direct interviews applied in the homes of residents of the country. A cross-sectional study was applied with this information collected during 2019 and 2020, with a final sample of 39 124 subjects, 15 974 from the year 2019 (62.03%) and 7088 from the year 2020 (55.54%). The dependent variable was access to oral health information and the independent variable was year; in addition, there were considered sociodemographic and geographical covariates. Finally, there were executed descriptive, bivariate, and multivariate analyses. Results: Access to oral health information was 59.85% (n = 23 062). For the bivariate analysis, the dependent variable showed association with year, natural region, sex, altitude, health insurance coverage, area, place of residence and wealth index. During multivariate analysis, year manifested a negative association with access to oral health information (aPR: 0.89; 95%CI: 0.85-0.92; P < 0.001), adjusted for co-variables that previously manifested association. Conclusion: Access to oral health information for Peruvian children had a negative impact during 2020, in which COVID-19 pandemic occurred.
