Oral/Perioral Reactions to Injectable Soft Tissue Fillers: A Clinicopathological Multicentric Study.

OBJECTIVE: To analyze the characteristics of a series of oral reactions to injectable soft tissue fillers. MATERIALS AND METHODS: Cases diagnosed as oral reactions to injectable soft tissue fillers were selected from eight Pathology laboratories. Information was retrieved from the laboratory charts and from the review of the hematoxylin and eosin-stained histological slides. RESULTS: The 151 patients showed a mean age of 54.9 years, and 136 (90.1%) were females. Mean time of onset was 20.4 months, and the lips were the most frequent location (72.8%). Most cases presented as asymptomatic isolated nodules, with a mean size of 17.4 mm. Silicone (38.5%), polymethylmetacrylate (33%), and hyaluronic acid (11.9%) were the three most common fillers. Granulomas, foamy macrophages, and multinucleated giant cells were observed in 44%, 51.5%, and 65.3% of the cases, respectively. Time of onset was shorter for males (p = 0.033), and symptoms were common in the upper lip, buccal mucosa, and lower vestibule (p = 0.010). Foamy macrophages were more common in association with silicone and collagen (p < 0.001), whereas multinucleated giant cells were more common in association with polymethylmetacrylate, hydroxiapatite, and polylactic acid (p = 0.012). CONCLUSION: Clinicians should consider reactions to injectable soft tissue fillers when evaluating asymptomatic submucosal nodules affecting the lips of adult/older females.

DESIGN: This is a pilot cross-sectional, applied, and quantitative study. SETTING: The study was conducted in two tertiary care treatment centers in Brazil. PARTICIPANTS: The participants included 20 caregivers and infants undergoing treatment with nasoalveolar molding (NAM) for CL ± P. INTERVENTIONS: The intervention involved using the TeleCleft mobile application for remote monitoring and guidance of caregivers and infants during NAM treatment. MAIN OUTCOME MEASURE(S): The main outcome measures included usability and satisfaction of users with the TeleCleft application. RESULTS: The results showed high usability and satisfaction ratings among users of the TeleCleft application. Most participants found remote monitoring to be effective and expressed positive opinions about its convenience and usefulness. CONCLUSION: TeleCleft could be a viable tool for remote monitoring and guidance, reducing the need for patients and caregivers to travel to treatment centers, which could potentially alleviate the burden of care faced by families during the journey of CL ± P treatment.

Digital resources in the monitoring of patients with cleft lip and palate: protocol for a scoping review.

INTRODUCTION: Cleft lip and/or palate (CL+/-P) is a congenital malformation affecting the lip and palate, requiring long-term treatment due to potential associated complications. For this reason, it is important for the patient to be continuously monitored and followed for health promotion and prevention, as well as improving the quality of life. The aim of this scoping review protocol is to identify and map the available evidence regarding the application of digital resources and technologies in the monitoring and follow-up of patients with CL+/-P. METHODS AND ANALYSIS: This scoping review protocol follows the guidelines recommended by the Joanna Briggs Institute Manual, employing the PCC acronym (Patient/Concept/Context). Searches will be conducted, in May 2024, of PubMed, Web of Science, Scopus, Latin American and Caribbean Health Sciences Literature, ScienceDirect, as well as grey literature indexed in ProQuest Open Access Dissertations & Theses and Google Scholar. The review will consider all types of published studies, including grey literature, in English, Portuguese and Spanish languages, and will consider studies regardless of publication date. Exclusions will apply to studies that do not address the use of digital resources and technologies in CL+/-P monitoring and follow-up. ETHICS AND DISSEMINATION: As this is a scoping review, no ethics committee approval is required. After completion, the plan is to publish results in scientific journals on craniofacial malformations. STUDY REGISTRATION: Open Science Framework, DOI:10.17605/OSF.IO/Y6AG8.

Oral Lymphatic Malformations: A 21-Year Retrospective Study in a Single Institution.

Introduction. Oral lymphatic malformations are uncommon lesions. This study assessed the clinicopathological and sociodemographic features of oral lymphatic malformations in a Brazilian oral pathology service. Methods. Between 2000 and 2021, all oral lymphatic malformations diagnosed in a single oral pathology service were selected for the study. Clinical data, such as age, sex, site of the lesion, clinical presentation, diagnosis clinical, and the type of biopsy were recorded from the patient's clinical charts. Results. From 7554 oral lesions, 17 (0.22%) were oral lymphatic malformations. This lesion similarly affected both sexes, and the mean age of the patients was 16.5 years. The tongue was the most common site (n = 13; 76%). The mean size of the lesions was 17 mm. Oral lymphatic malformations were asymptomatic for 29% of the patients. Clinically, most lesions appeared as a reddish, sessile nodule, with a pebbly surface. In addition, the clinical and histopathological diagnoses agreed for most lesions (n = 11; 64%). The type of biopsy performed was excisional in 41% of lesions. Conclusions. In summary, oral lymphatic malformations present a low prevalence among the oral lesions diagnosed in an oral pathology service. Moreover, they affect equally both sexes, especially young patients, and usually appear as an asymptomatic or symptomatic nodular swelling on the tongue.

Telehealth in oral medicine: A cross-sectional evaluation based on a mobile application.

BACKGROUND: Teledentistry is considered a good tool in the diagnostic process. In oral medicine, there is a low number of trained professionals and dentists have difficulty in diagnosing and treating oral lesions. OBJECTIVE: We aimed to perform a cross-sectional evaluation based on the mobile application for oral diagnosis using a mobile application in a Brazilian State. METHODS: This is a retrospective, cross-sectional, observational study of the data of the "Telehealth in Stomatology in Paraíba" carried out between May 2021 and November 2022. RESULTS: The app has a team of 16 consultants (Ph.D. professors, postgraduate students, residents, and dentists). In addition, there are 289 registered professionals, with a mean age of 33.7 years, predominantly female (70.2%), working in primary care (79.2%), and general practitioners (42.6%). Regarding the cases, the app has 194 cases, and reactive lesions are the most suggested hypotheses reported by dentists (24.5%) and consultants (22.3%). We had an overall concordance rate of 64.1%. CONCLUSION: The application is easily accessible and has an assistance network that helps with early diagnosis. In addition, it has good coverage with users in more than 50% of the cities in the state. Thus, applications that provide specialized care to distant areas are important for better public health.

Effect of multidrug solution for the treatment of chemotherapy-induced oral mucositis in vivo.

Objective: Evaluate the effect of a multidrug solution, adopted by a referral hospital for cancer to control and treat chemotherapy-induced oral mucositis in rats. Methods: Oral mucositis (OM) was induced by 5-Fluorouracil (5-FU), and the animals were treated with saline (n = 8, G1), 0.12% chlorhexidine (n = 8, G2); and multidrug solution (n = 8, G3). The animals were submitted to clinical and histological analysis of the lesion using mucosal fragments. The animals' food consumption during treatment was also evaluated. Results: Clinical improvement (p < 0.05) was observed in the groups treated with the multidrug solution and 0.12% chlorhexidine digluconate. In G2 and G3, there was a prevalence of reepithelialization covering <50% of the lesion. Evaluation of the inflammatory infiltrate indicated that the G1 treatment permitted an intense inflammatory response in all animals, yet this evaluation parameter was moderate in groups G2 and G3. The G3 group (p < 0.05) presented higher food consumption than the other groups. Conclusions: The multidrug solution improved the clinical and histological parameters of the chemotherapy-induced oral mucositis, as well as promoted an increase in food intake.

Oral Mucositis in Children with Leukemia Undergoing Chemotherapy: A Case Series

ABSTRACT Objective: To report nine cases of pediatric patients with Acute Lymphoid Leukemia (ALL) or Acute Myeloid Leukemia who developed severe oral mucositis (SOM) at the first week of chemotherapy. Material and Methods: The cases were selected from a sample of 105 children followed for 10 consecutive weeks. Hematological and personal data were obtained from the patient's medical records. The oral cavity was examined weekly using the modified Oral Assessment Guide. Results: More of the patients were male (55.6%), had black/brown skin (55.6%), with ALL (66.7%), and the mean age was 5.55. Two patients had values below normal for leukocytes, platelets, and creatinine over the follow-up. However, all patients showed changes in the normality of hematological data in most weeks. The most used chemotherapeutic agents were aracytin, etoposide, and methotrexate, known for their high stomatotoxic potential. Patients had 2 to 6 (mean of 4) episodes of SOM and 4 to 7 (mean of 5.5) episodes of OM. One patient at week 7, one patient at week 5, and one patient at weeks 2 and 10 did not have OM. Saliva (84 times) and lips (44 times) were the most affected items. Conclusion: The patients showed oscillations in the severity of oral mucositis and hematological parameters over the follow-up. All patients were exposed to stomatotoxic drugs during the initial phase of cancer treatment.

Controlled release and antiviral activity of acyclovir-loaded PLA/PEG nanofibers produced by solution blow spinning.

Herpetic dermatitis and oral recurrent herpes (ORH) are among the most common human infections. Antiviral drugs such as acyclovir (ACV) are used in the standard treatment for ORH. Despite its therapeutic efficacy, ACV is continuously and repetitively administered in high doses. In this sense, the development of controlled release drug delivery systems such as core-shell fibers have a great potential in the treatment of ORH. In this work, poly(lactic acid)/poly(ethylene glycol) (PLA/PEG) fibers were produced by solution blow spinning (SBS) for the controlled release of ACV encapsulated in the core. PLA/PEG nanofibers containing four different blend ratios (100:0, 90:10, 80:20 and 70:30 wt%) without or with 10 wt% ACV were characterized by scanning electron microscopy (SEM), thermogravimetry (TG) and differential scanning calorimetry (DSC). The ACV release profile for 21 days was accessed by UV-Vis spectroscopy. Static water contact angles of the spun fiber mats were measured by the sessile drop method to evaluate fiber wettability upon contact with skin for transdermal release. Cytotoxicity and antiviral efficacy against Herpes simplex viruses (HSV-1) were evaluated using Vero cells. ACV addition did not impact on morphology, but slightly improved thermal stability of the fibers. Addition of hydrophilic PEG in PLA/PEG blends, however, increased drug release as confirmed by contact angle measurements and release profile. The in vitro tests showed the effectiveness of the drug delivery systems developed in reducing HSV-1 viral titer, which is related to the judicious combination of polymers used in the fibrous mats, in addition to not being cytotoxic to Vero cells. These results show the great potential of PLA/PEG solution blow-spun fibers in the controlled release of ACV to develop practical devices for the treatment of cold sores, while favoring the aesthetic appearance by covering them with a soft tissue patch (fibrous mats).

Impact of COVID-19 on dental practice and anxiety among increased risk group dentists: A cross-sectional study.

BACKGROUND: The likelihood of infection with SARS-COV-2 (COVID-19) in the dental office is considered high. OBJECTIVES: Assessing the impact of the COVID-19 on dental practices and anxiety levels in risk group Brazilian dentists. METHODS: A cross-sectional study was performed using an online questionnaire. The data obtained were analyzed using the IBM SPSS 25.0 software (Pearson's Chi-square association test, multivariate logistic regression, and Poisson multiple regression), with subsequent calculation of the odds ratio at a 95% confidence interval, with a significance level of 5%. RESULTS: Responses of 578 dentists distributed in all regions of Brazil were collected. Most of the dentists were female, with an average age of 35. Of the participants, 23.4% were part of the increased risk group for COVID-19. The professionals who belonged to the increased risk group had a greater chance of not feeling prepared to perform consultations (OR = 1.67) and were not performing any procedures during the pandemic (OR = 2.03). Belonging to the increased risk group did not influence anxiety levels among the dentists. The factors associated with increased anxiety were being female, being younger, working in the southeastern region of the country, being afraid of contracting COVID-19 while working, and being concerned for one's professional future. CONCLUSIONS: The pandemic has had a negative impact on the professional practice of individuals at risk, but the level of anxiety was like professionals who were not part of the increased risk group for COVID-19.

Evaluation of the economic impact of COVID-19 on Brazilian private dental clinics: A cross-sectional study.

BACKGROUND: The changes in dental care in the face of the COVID-19 pandemic resulted in the need for greater financial investment by dentists in biosafety measures and increase in the costs of dental consultations. OBJECTIVE: To evaluate the economic impact of the COVID-19 pandemic on dental practices in private clinics in Brazil. METHODS: A cross-sectional study was carried out, using an online questionnaire indexed in Google Forms, and distributed among dentists. The data obtained were analyzed using the IBM SPSS 25.0 software, evaluating the factors associated with strong or very strong impact on the participants' income and the factors that motivated the dentists to look for a credit line. Multiple logistic regression models were constructed to identify the associated factors. Variables with p < 0.05 were considered statistically significant. RESULTS: Most participants were female, with a median age of 35 years. Dentists who are most concerned about their professional future (OR = 3.134; 95% CI: 1.804-5.445), who have longer office hours (OR = 2.056; 95% CI: 1.198-3.529), who had the greatest impact on the flow of patients (OR = 16.358; 95% CI: 9.408-28.443) and in need of investing in infrastructure (OR = 1.756; 95% CI: 1.014-3.041), had the greatest impact on monthly earnings. CONCLUSIONS: The pandemic and the new biosafety recommendations for care during this period had a negative impact on the income of Brazilian dental offices and increased the chance of seeking credit to alleviate the financial deficit.

Oral squamous cell carcinoma outcome in adolescent/young adult: Systematic review and meta-analysis.

To perform a systematic review focusing on the prognosis of oral cavity squamous cell carcinoma (OSCC) in young patients (≤40 years old) compared to older (>40 years old). Four databases were used in our search strategy. First, all titles were systematically organized using the Covidence platform online. In the second phase, 118 full texts of potentially eligible studies were analyzed by reviewers independently and in pairs. Twelve studies were considered eligible for data extraction. The relapse was higher in the young than in controls (pooled relative risk (RR) = 1.31; 95% CI [1.10-1.56]). The 5-year disease-free survival (DFS) was worse in young group (pooled hazard ratio (HR) = 0.73; 95% CI [0.63-0.85]) but the 5-year overall survival (OS) estimate was similar between the groups (pooled HR = 0.84; 95% CI [0.70-1.00]). While the 5-year OS was similar between groups, the number of relapses and 5-year DFS were worse in patients with OSCC ≤40 years old.

Impact of COVID-19 on Oral Healthcare for Oncopediatric Patients: The Setting in a Reference Hospital in Northeast Brazil

Abstract Objective: To describe the impact of the COVID-19 pandemic on dental care provided to pediatric cancer patients assisted in a referral hospital. Material and Methods: This is an observational, retrospective study based on secondary data extracted from worksheets of dental procedures for patients aged between 0 and 19 years assisted in the pediatric oncology sector of a hospital in João Pessoa, PB, Brazil. Dental procedures performed by the interdisciplinary team of researchers from August 2018 to February 2020 (19 months prior to the pandemic) and from April 2020 to October 2021 (19 months during the pandemic) were totaled and compared. A descriptive analysis of the data was performed. Results: There was a reduction of 80.2% in dental interventions implemented in the sector during the pandemic, with the number of procedures decreasing from 6,210 (the period before the pandemic) to 1,229 (during the pandemic). Most procedures in both periods were performed for patients assisted in beds, for whom there was a reduction of care provided for 81.2% from 5,275 to 994 procedures. Dental procedures in the outpatient clinic decreased by 74.9%, from 935 to 235. Conclusion: The COVID-19 pandemic negatively impacted dental care provided to pediatric oncology patients by restricting dental procedures to emergency demands, compromising performance prevention and health promotion actions.

Use of collaborative learning as atool to evaluate syndromic craniofacial anomalies / Uso da aprendizagem colaborativa como ferramenta para avaliar anomalias craniofaciais sindrômicas

Almost 30% of oral cleftsare associated with other structural abnormalities.However, little is known on orofacial characteristics related tothese cases since they are not systematically reported. To close this gap, we developed a collaborative learning approach supported by an interprofessional team aiming to systematicallydescribe oral findings and impactthe training of future professionals that hopefully will incorporate these descriptionsintotheir clinical practice. The methodological proposal consisted of small group sessions focusing on a particular syndrome or group of syndromes followed by examiningpatients with those conditions. Twenty cases were examined and studied over one semester andaset of conditions to be identified in the orofacial regionwasdefined. Here, we present a guideline that we suggest that dentists and dental institutions use. We also present the advantages of using collaborative learning as a tool in the training of the clinician (AU).

Quase 30% das fissuras orais estão associadas a outras anormalidades estruturais. No entanto, pouco se sabe sobre as características orofaciais relacionadas a esses casos, uma vez que não são relatados de forma sistemática. Para fechar essa lacuna, desenvolvemos uma abordagem de aprendizagem colaborativa apoiada por uma equipe interprofissional com o objetivo de descrever sistematicamente os achados orais e impactar o treinamento de futuros profissionais que, esperançosamente, irão incorporar essas descrições em sua prática clínica. A proposta metodológica consistia em sessões de pequenos grupos enfocando uma determinada síndrome ou grupo de síndromes seguidas de exame de pacientes com essas condições. Vinte casos foram examinados e estudados ao longo de um semestre e foi definido um conjunto de condições a serem identificadas na região orofacial. Aqui, apresentamos uma diretriz que sugerimos que os dentistas e instituições odontológicas utilizem. Também apresentamos as vantagens de usar a aprendizagem colaborativa como uma ferramenta no treinamento do clínico (AU).

This study presents challenges related to the fulfillment of the new biosafety protocols aiming to return the face-to-face activities in higher education institutions in Dentistry considering the pandemic scenario of COVID-19. It was a qualitative, exploratory study, anchored in the technique of documentary research. We analyzed documents published by the Ministry of Education(MEC), the Federal Council of Dentistry (FCD) and the Brazilian Association for Dental Education (BADE). The documents were collected on websites of the selected entities. The treatment of qualitative data obtained was carried out by thematic content analysisto compare qualitatively the different documents by identifying convergent, divergent or absent points between them. From the problematization of the object under study, suggestions were made based on the weaknesses and potentialities related to the execution of the recommendations. Data were distributed in the analysis units "waiting room", "clinic" and "laboratory". The main potentialities were related to the reduction of the biological risk of transmission of pathogens and the adaptation of physicalspaces in more ergonomic learning environments. As for the weaknesses, there are increased costs for students and institutions and reduced number of visits. There are challenges to be considered to comply with the new biosafety protocols in the return of practical activities in Dentistry Courses during the COVID-19 pandemic (AU).

COVID-19 Pandemic Causes Increased Clinic Visits with Diagnosis of Tegumentary Leishmaniasis in Brazil in 2020.

Coronavirus disease 2019 (COVID-19) protocols has reduced primary and secondary health care for other diseases, such as leishmaniasis, a parasitic, endemic, chronic and persistent disease in Brazil. To ascertain this, we compared the number of leishmaniasis cases diagnosed before and after the COVID-19 pandemic. In 5 regions of Brazil, there was an increase in the mean number of leishmaniasis clinic visits from 2020 pandemic period (over 57%) compared with 2017-2019 years. Interestingly, this increase was due to tegumentary leishmaniasis (TL) while visceral leishmaniasis consultations decreased considerably. The increase in clinic visits with a diagnosis of TL in all regions of Brazil during the pandemic period in 2020, shows that the epidemiological surveillance of neglected tropical diseases cannot slowdown in the country. Expanding information can minimize the negative impacts of COVID-19 on health promotion, prevention and monitoring of the most prevalent neglected diseases.

Self-regulated learning perception of undergraduate dental students during the COVID-19 pandemic: A nationwide survey in Brazil.

BACKGROUND: This study aimed to evaluate the perception of self-regulated learning of Brazilian undergraduate dental students during the COVID-19 pandemic. MATERIAL AND METHODS: A nationwide cross-sectional survey was conducted. Data were collected in 2020, through an anonymous self-administered virtual questionnaire, which comprised an initial section related to the students' sociodemographic data, category of educational institution where they enrolled, and the possible impacts of COVID-19 pandemic on family income, teaching activities (maintained remotely or totally suspended), and self-perception of academic performance during e-learning. The second part comprising 31 questions related to the adapted Self-Regulated Learning Perception Scale (SRLPS). For statistical analysis, Student's t-test of independent samples, Kruskal-Wallis, and Mann-Whitney U test were used, considering a significance of 5%. RESULTS: From 779 students, 425 (54.6%) reported distance learning activities during the pandemic, and 354 (45.4%) experienced complete interruption of teaching activities. Students with good performance during e-learning were more skilled in self-regulated learning when compared to those who reported regular (p = 0.026), bad (p = 0.000), and very bad (p = 0.000) performance. In addition, students who stated a good performance during e-learning were more skilled in self-regulated learning than those with fully suspended teaching activities (p = 0.000). CONCLUSIONS: E-learning performance of undergraduate dental students during COVID-19 pandemic influenced the self-regulated learning perception. In addition, the pandemic negatively impacted the self-regulated learning of students who experimented full suspension of teaching activities. Changes in family's income did not affect their self-regulated learning. Key words:Dental education, community health, e-learning, learning, pandemics.

The impact of the COVID-19 pandemic on undergraduate and graduate dental courses in Brazil.

BACKGROUND: The COVID-19 pandemic has raised challenges in adapting to teaching and learning methods in dental education. OBJECTIVE: This study aimed to evaluate the impact of the COVID-19 pandemic on the academic activities of undergraduate (UDG) and graduate (GD) dental students in Brazil. Additionally, students' perceptions and attitudes toward teaching activities during this period were analyzed. METHODS: A nationwide cross-sectional survey was conducted with a sample of Brazilian UDG and GD dentistry students. Data were collected in 2020 through an online, self-administered, and anonymous questionnaire, which comprised 26 questions related to demographic data, activities of the college, family and individual student income, and attitudes and perceptions about e-learning during the pandemic. The data were tabulated and analyzed using descriptive statistics. RESULTS: The sample included 1,166 students (779 UDG and 387 GD). Among these, 425 (54.6%) UDG and 270 (69.8%) GD students remotely participated in teaching activities, of which 42.6% of the UDG considered their performance in e-learning to be bad or very bad and 49.8% of the GD regarded it as good or excellent. The survey also showed that 354 (45.4%) UDG and 102 (26.4%) GD expressed a desire to discontinue the course following the outbreak of the pandemic. Among the GD, 225 (58.4%) said that their experiments were completely interrupted. CONCLUSIONS: This study reveals the poor perception and performance of dental students regarding e-learning. Additionally, the findings suggest a negative impact of the pandemic on dental education in Brazil. Effective measures should be taken to mitigate these significant consequences.
