Outpatient and inpatient dental care for patients with disabilities in Brazil's public healthcare system: A population-based approach from 2014 to 2023.

AIM: The aim of this study was to evaluate outpatient and inpatient dental care for patients with disabilities from 2014 to 2023. MATERIAL AND METHODS: A time series analysis was carried out with data from Brazil's public healthcare system, considering the outpatient productivity of Special Needs Dentistry specialists and hospitalizations (inpatient admissions) of patients with disabilities for dental procedures, both normalized to every 100,000 inhabitants (incidence). The significance level was set at 5%. RESULTS: In the last 10 years, 22,420,859 procedures were carried out and 89,380 hospitalizations were approved. Trend analysis showed no significant temporal variation in the incidence of both variables. Regarding the procedures, the majority were low-complexity (82.1%, p < .001) and clinical (71.2%, p < .001). Periodontal (19.9%) and restorative (19.5%) procedures were the most frequent. Considering the hospitalizations, almost (R$) 40 million was allocated, and the majority were classified as elective (71.9%, p = .002) and of short duration (less than a day). CONCLUSION: Dental care for patients with disabilities presented patterns related to the types of procedures, complexity and circumstance, in addition to not showing significant temporal variation over the last 10 years.

Inflammatory response to bioceramic and epoxy resin-based endodontic sealers implanted in mice subcutaneous tissue: An in vivo study.

To evaluate the inflammatory tissue response to BioRoot™ RCS (BR) and AH Plus Jet (AHPJ) sealers implanted in mice subcutaneous tissue. It was hypothesized that the inflammatory tissue response to BR would be milder than to AHPJ. An in vivo study was carried out using isogenic mice. The sealers were implanted during standardized surgical procedures. The inflammatory response was evaluated by microscopic analysis and von Kossa reaction in the reactionary tissue around the specimens after 7, 21, and 63 days. For comparisons, a zinc oxide and eugenol sealer (ZOE) was used as a positive control, in addition to a negative control without a sealer (n = 10 per group/period). All statistical analyses considered a significance level of 5%. All endodontic sealers triggered an inflammatory tissue response after 7 days. BR had a higher inflammatory cell count and a thicker fibrous capsule when compared with AHPJ, but both were less inflammatory than ZOE (p < .001). After 21 days, BR continued to trigger an intense inflammatory tissue response, higher in both microscopic parameters compared to AHPJ, and a thicker fibrous capsule than ZOE (p < .001). After 63 days, the inflammatory tissue response decreased in BR, matching the fibrous capsule thickness with AHPJ and ZOE. BR promoted intense calcium precipitation in all study periods. After 63 days, AHPJ and BR sealers were more biocompatible to subcutaneous mice tissue, but AHPJ present better early inflammatory response, as well as BR showed potential bioactivity. RESEARCH HIGHLIGHTS: The inflammatory tissue response triggered by a bioceramic endodontic sealer (BR) was not milder than that triggered by an epoxy-resin based endodontic sealer (AHPJ) during the first 3 weeks, considering the microscopic analysis of the reactionary tissue.

Outpatient dental procedures carried out by Pediatric Dentists within Brazil's public healthcare system.

Brazil's public healthcare system (SUS) offers specialized oral health services to Brazilians, but the productivity of specialists, such as Pediatric Dentists, has not been characterized. Therefore, the objective of this study was to characterize the outpatient dental procedures (ODPs) carried out by Pediatric Dentists within the SUS. An epidemiological study with an ecological, longitudinal, retrospective, and quantitative approach was conducted. The ODPs carried out by Pediatric Dentists within the SUS were characterized based on type of procedure, complexity level, and circumstance (urgent or elective). Data were analyzed using a descriptive and analytical approach, considering a significance level of 5%, as well as the impact of the COVID-19 pandemic (the 2020-2022 years were not included in secondary analyses). In the last 15 years, 29,234,972 ODPs were carried out by Pediatric Dentists within the SUS. Clinical procedures were the majority (55.4%), significantly more frequent than all other types of procedures (all p <0.05). Among these, restorative and periodontal procedures were the most common (30.7% and 21.0%, respectively). From 2008 to 2019, excluding COVID-19 pandemic years, the trend over the last 15 years was constant for all types of procedures (all p >0.05). In addition, low complexity ODPs were the majority (90.1%), significantly more frequent than medium (9.7%) and high complexity procedures (0.1%) (both p <0.05). At last, most ODPs were not characterized by circumstance in the outpatient production reports (96.9%). Therefore, it was possible to conclude that Pediatric Dentists carried out diverse ODPs within the SUS over the past 15 years, although there was a dominant pattern of type and complexity.

Territorial Disparities in Dental Care for Disabled Persons and Oral Health-Related Indicators: A Population-Level Approach in Brazil's Public Healthcare System from 2014 to 2023.

This study evaluated territorial disparities in dental care for disabled persons in Brazil's public healthcare system from 2014 to 2023. The person-year incidence of outpatient dental procedures carried out by special care dentistry specialists and hospitalizations for dental procedures for disabled persons were compared across different regions and against the national estimate. In addition, productivity was correlated with oral health-related indicators. The significance level was set at 5%. The northern region exhibited the highest outpatient productivity, while the southern region showed lower productivity compared to the national estimate (both p-value < 0.05). This pattern was reversed in inpatient productivity (both p-value < 0.05), with the northeastern and central-western regions also below average (both p-value < 0.05). There were no significant correlations between the indicators and inpatient productivity, but outpatient productivity was positively correlated with the proportions of inhabitants who self-rated their general and oral health as "poor" or "very poor", who have never visited a dentist, and who visited a dentist for tooth extraction (all p-values < 0.05). Territorial disparities in dental care for disabled persons were observed within Brazil's public healthcare system, and they were correlated with unfavorable oral health-related indicators at the population level.

The effects of NLRP3 inflammasome inhibition or knockout in experimental apical periodontitis induced in mice.

OBJECTIVE: To evaluate the effects of NLRP3 inflammasome inhibition or knockout in experimental apical periodontitis (AP) induced in mice. METHODS: The experimental AP was induced by pulpal exposure. To evaluate NLRP3-specific inhibitor medication (MCC950), WT mice received intraperitoneal injections, while the control received PBS (n = 10). In addition, to evaluate NLRP3 knockout, 35 wild-type (WT) and 35 NLRP3-/- mice were divided into a control group (without pulpal exposure, n = 5) and three experimental groups: after 2, 14 and 42 days after pulpal exposure (n = 10). Microscopic and molecular analyzes were carried out using a significance level of 5%. RESULTS: Exposure to MCC950 did not affect the periapical lesion size after 14 days (P = 0.584). However, exposed mice had a lower expression of IL-1ß, IL-18 and caspase-1 (P = 0.010, 0.016 and 0.002, respectively). Moreover, NLRP3-/- mice showed a smaller periapical lesion after 14 and 42 days (P = 0.023 and 0.031, respectively), as well as a lower expression of IL-1ß after 42 days (P < 0.001), of IL-18 and caspase-1 after 14 (P < 0.001 and 0.035, respectively) and 42 days (P = 0.002 and 0.002, respectively). NLRP3-/- mice also showed a lower mRNA for Il-1ß, Il-18 and Casp1 after 2 (P = 0.002, 0.036 and 0.001, respectively) and 14 days (P = 0.002, 0.002 and 0.001, respectively). CONCLUSIONS: NLRP3 inflammasome inhibition or knockout can attenuate the inflammatory events that result in the periapical lesion (AP) formation after pulpal exposure in mice. CLINICAL RELEVANCE: The NLRP3 inflammasome may be a therapeutic target for AP, and new approaches may verify the impact of its inhibition (through intracanal medications or filling materials) on the bone repair process and treatment success.

Root canal conicity determination of primary second molars using nanotomography: An in vitro study.

BACKGROUND: The conicity of the root canals of primary teeth is an important measure for endodontic therapies. However, determining this conicity depends on the methods employed, which requires further investigation. AIM: The aim of this study was to determine the conicity of the root canals of the upper and lower primary second molars using nanotomography (nCT). DESIGN: An in vitro study was performed using nine primary second molars, both upper and lower, subjected to nCT. Comparisons between the diameters of root canals were performed between the thirds (cervical-D0, middle-D5, and apical-D7). The conicity (%) was determined for each root canal from cervical to apical. Data were statistically analyzed with a significance level of 5%. RESULTS: The conicity ranged from 2% to 8% for the upper primary second molars. Significant differences in root canal diameter between the thirds (D0, D5, and D7 points) were observed in the mesio- and distobuccal roots (p < .05), but not in the palatal roots (p > .05). For the lower primary second molars, the conicity ranged from 2% to 17%, as well as significant differences in root canal diameter between the thirds (D0, D5, and D7 points) were observed in all roots (distal, mesiobuccal, and mesiolingual; p < .05). CONCLUSION: The conicity of the upper primary second molars was different from that of the lower ones, which showed a greater variability.

Activation of gelatinases in permanent human teeth after different experimental radiotherapy protocols.

The objective of this study was to compare the activation of gelatinases in dentin-enamel junction (DEJ) and underlying dentin of permanent teeth after experimental radiotherapy in conventional and hypofractionated modalities. Newly extracted third molars (n = 15) were divided into three experimental radiotherapy groups: control, conventional (CR), and hypofractionated (HR) (n = 5 per group). After in vitro exposure to ionizing radiation, following standardized protocols for each modality, a gelatinous substrate was incubated on the tooth slices (n = 10 per group). Activation of gelatinases was measured by in situ zymography, expressed in arbitrary fluorescence units (mm2) from three tooth regions: cervical, cuspal, and pit. Fluorescence intensity was compared among radiotherapy protocols and tooth regions in each protocol, considering a significance level of 5%. Considering all tooth regions, the fluorescence intensity of the CR group was higher than the HR and control groups, both in DEJ and underlying dentin (p <0.001). In addition, the fluorescence intensity was higher in underlying dentin when compared to DEJ in all groups (p <0.001). Considering each tooth region, a statistically significant difference between CR and HR was only observed in the pit region of underlying dentin (p <0.001). Significant and positive correlations between fluorescence intensities in DEJ and underlying dentin were also observed (p <0.001). Experimental radiotherapy influenced the activation of gelatinases, as well as exposure to the conventional protocol can trigger a higher activation of gelatinases when compared to hypofractionated, both in DEJ and underlying dentin.

Caries-related hospital morbidity in the Brazilian Unified Health System from 2008 to 2022.

Dental caries is an important Public Health issue. However, the treatment of this disease in tertiary dental care requires further investigation. Therefore, the objective of this study was to evaluate caries-related hospital morbidity in the Brazilian Unified Health System (SUS) from 2008 to 2022. An ecological study was conducted with secondary data on caries-related Hospital Admission Authorizations (AIH) and in-hospital dental procedures (IDP). Data were collected nationwide and statistical analysis was performed with a significance level (p) of 5%. In the last 15 years, 3,474 caries-related AIH and 63,657 IDP were approved within SUS. There was a significant upward trend in the number of caries-related AIH (p = 0.018) and a stationary trend in the number of caries-related IDP (p = 0.841). Moreover, from 2008 to 2022, R$ 1,160,843.09 was allocated for caries-related AIH. Hospital mortality was 0.29% (10 deaths), and 75.1% were elective inpatient admissions. Among SUS users, adults constituted the majority (49%), with a higher frequency of males (59.8%) and whites (46.2%). The most frequent type of caries-related IDP was restoration of permanent teeth (55.3%). Nonetheless, during the COVID-19 pandemic years, significant reductions in caries-related AIH and IDP within the SUS were observed (all p <0.05). Thus, within the SUS, caries-related tertiary dental care has shown a specific pattern over the last 15 years, including an increase in hospitalizations and a high number of in-hospital dental procedures, especially before the COVID-19 pandemic onset.

Introdução: A maioria das crianças apresenta doença ou agravo de saúde que necessita de assistência hospitalar (incluindo internação) em algum momento de sua infância. Os impactos da internação podem ocorrer no crescimento e desenvolvimento infantil e nos custos envolvidos. Objetivo: Avaliar a morbidade hospitalar de crianças de zero a nove anos no Hospital Universitário de Lagarto (HUL), Sergipe, Brasil, nos últimos dez anos. Material e Métodos: Foi realizado um estudo ecológico, do tipo série temporal, considerando a quantidade anual internações hospitalares como variável primária. Foi estimada a tendência temporal da incidência entre 2013 e 2022, além de descrever indicadores de morbidade e comparar a incidência em relação ao sexo, faixa etária e CID-10. O nível de significância foi de 5%.Resultados: Nos últimos dez anos, quase seis mil internações hospitalares de crianças de zero a nove anos foram aprovadas no HUL. O valor médio de cada internação hospitalar foi de R$433,61 com tempo médio de permanência foi de 4,8 dias. A tendência temporal foi estacionária para todas as faixas etárias (menores de um ano, entre um e quatro e entre cinco e nove anos) (p >0,05). Entretanto, a incidência de hospitalizações de crianças menores de um ano foi significativamente maior quando comparada às outras faixas etárias (p <0,05), assim como de crianças do sexo feminino em relação ao masculino (p <0,05). Por fim, observou-se que as doenças do aparelho respiratório foram as mais comuns, cuja incidência foi significativamente superior a todos os outros grupos de doenças do CID-10 (p <0,05). Conclusão: Nos últimos dez anos, o HUL apresentou um padrão morbidade hospitalar com maior prevalência de internações em crianças de 1 a 4 anos e por causas respiratórias.

Introduction: Most children have a disease or health problem that requires hospital care during childhood, including hospitalization. However, child-related hospital morbidity needs further investigation. Objective: To evaluate the child-related hospital morbidity of children from zero to nine years old at the University Hospital of Lagarto (HUL), Sergipe, Brazil, in the last ten years. Material and Methods: An ecological time-series study was carried out, considering the number of annual hospital admissions as the primary variable. The temporal trend of incidence between 2013 and 2022 was estimated, in addition to describing morbidity indicators and comparing the incidence in relation to sex, age group and ICD-10. Results: In the last ten years, almost six thousand hospital admissions of children from zero to nine years old were approved at the HUL. The average value of each hospitalization was R$433.61, with an average length of stay of 4.8 days. The temporal tendency was stationary for all age groups (under one year old, between one and four, and between five and nine years old) (p >0.05). However, the incidence of hospitalizations of children under one year old was significantly higher when compared to other age groups (p <0.05), as well as female children when compared to male (p <0.05). Finally, it was observed that respiratory system diseases were the most common, whose incidence was significantly higher than all other ICD-10 disease groups (p <0.05). Conclusion: In the last ten years, HUL has presented a pattern of hospital morbidity with a higher prevalence of hospitalizations in children aged 1 to 4 years and for respiratory causes.

After in vitro exposure to ionizing radiation, following standardized protocols for each modality, a gelatinous substrate was incubated on the tooth slices (n = 10 per group). Activation of gelatinases was measured by in situ zymography, expressed in arbitrary fluorescence units (mm2) from three tooth regions: cervical, cuspal, and pit. Fluorescence intensity was compared among radiotherapy protocols and tooth regions in each protocol, considering a significance level of 5%. Considering all tooth regions, the fluorescence intensity of the CR group was higher than the HR and control groups, both in DEJ and underlying dentin (p <0.001). In addition, the fluorescence intensity was higher in underlying dentin when compared to DEJ in all groups (p <0.001). Considering each tooth region, a statistically significant difference between CR and HR was only observed in the pit region of underlying dentin (p <0.001). Significant and positive correlations between fluorescence intensities in DEJ and underlying dentin were also observed (p <0.001). Experimental radiotherapy influenced the activation of gelatinases, as well as exposure to the conventional protocol can trigger a higher activation of gelatinases when compared to hypofractionated, both in DEJ and underlying dentin.

Resumo O objetivo deste estudo foi comparar a ativação de gelatinases na junção dentina-esmalte (DEJ) e na dentina subjacente de dentes permanentes após a radioterapia experimental nas modalidades convencional e hipofracionada. Os terceiros molares recém-extraídos (n = 15) foram divididos em três grupos de radioterapia experimental: controle, convencional (CR) e hipofracionada (HR) (n = 5 por grupo). Após a exposição in vitro à radiação ionizante, seguindo protocolos padronizados para cada modalidade, um substrato gelatinoso foi incubado nas fatias de dente (n = 10 por grupo). A ativação das gelatinases foi medida por zimografia in situ, expressa em unidades arbitrárias de fluorescência (mm2) de três regiões do dente: cervical, cúspide e fossa. A intensidade da fluorescência foi comparada entre os protocolos de radioterapia e as regiões do dente em cada protocolo, considerando um nível de significância de 5%. Considerando todas as regiões do dente, a intensidade de fluorescência do grupo CR foi maior do que a dos grupos HR e controle, tanto no DEJ quanto na dentina subjacente (p <0,001). Além disso, a intensidade da fluorescência foi maior na dentina subjacente quando comparada à DEJ em todos os grupos (p <0,001). Considerando cada região do dente, uma diferença estatisticamente significativa entre CR e HR foi observada apenas na região da fossa da dentina subjacente (p <0,001). Também foram observadas correlações significativas e positivas entre as intensidades de fluorescência no DEJ e na dentina subjacente (p <0,001). A radioterapia experimental influenciou a ativação das gelatinases, assim como a exposição ao protocolo convencional pode desencadear uma maior ativação das gelatinases quando comparada ao hipofracionamento, tanto no DEJ quanto na dentina subjacente.

Online teaching, quality of life and anxiety of Brazilian dental professors during the COVID-19 outbreak.

The COVID-19 pandemic led to changes in academic teaching and dental education, but the impact on dental professors' mental health and quality of life remains poorly understood. Thus, the objective of this study was to evaluate the impacts of social distancing and online teaching related to COVID-19 on the quality of life and anxiety of Brazilian dental professors. This was a cross-sectional study conducted from August 2020 to October 2020. Three instruments were used in an online version: a questionnaire about personal data, academic information and online teaching activities, the Generalized Anxiety Disorders 7 (GAD7) scale, and the Abbreviated World Health Organization Quality of Life (WHOQOL-bref) scale. All instruments were sent by e-mail, social media, and messaging apps to private and public universities and professors. Of the 318 responses, 187 (58.8%) were from female professors. Moreover, lack of good internet access and adequate place for online teaching, difficulties in producing teaching materials, and housework roles had a significant impact on the quality of life and anxiety scores (all p-values < 0.05). Also, Brazilian dental professors who declared that they would make greater efforts if the activities were face-to-face had significantly worse quality of life and anxiety scores, and female professors had significantly higher anxiety scores (all p-values < 0.05). These results provide evidence of a negative effect of social distancing and online teaching activities related to COVID-19 outbreak on the health-related quality of life and mental health of Brazilian dental professors.

Disseminated dermatophytosis and acquired immunodeficiency syndrome: literature review and presentation of clinical experience / Dermatofitose disseminada e síndrome da imunodeficiência adquirida: revisão de literatura e apresentação de experiência clínica

Introduction: Dermatophytosis are very common fungal infections caused by the fungal species Microsporum, Epidermophyton or Trichophyton, which mostly affect the skin, the interdigital region, groin and scalp. Although they do not cause serious diseases, in patients with the human immunodeficiency virus the infection manifests itself and evolves exuberantly, usually with extensive and disseminated lesions. Objective: To review the literature on dermatophytosis in people living with human immunodeficiency virus and to present the experience in clinical care in a patient living with human immunodeficiency virus with extensive and disseminated dermatophytosis. Methods: A literature review on the topic was carried out in the PubMed/National Library of Medicine ­ USA databases, using the keywords dermatophytosis, or dermatophytosis associated with the words AIDS, human immunodeficiency virus or immunodeficiency, from 1988­2022. The clinical experience showed a patient living with human immunodeficiency virus developing AIDS and presenting with disseminated skin lesions. Samples of the lesion were collected by scraping, which were submitted to culture and there was growth of fungi of the Trichophyton sp genus. A biopsy of the lesion was also performed using the Grocott-Gomori's Methenamine Silver stain. Results: We found 1,014 articles, of which only 34 presented a direct correlation with our paper, and were used to discuss the main themes narrated in this article. We present clinical experience in the management of a patient with human immunodeficiency virus/AIDS and low adherence to antiretroviral treatment, showing extensive and disseminated erythematous-squamous lesions with a clinical diagnosis of tinea corporis, manifesting with a clinical picture usually not found in immunocompetent patients. The diagnosis was confirmed by laboratory tests with isolation of the Trichophyton sp fungus. The patient was treated with oral fluconazole, with complete remission of the clinical picture after two months. She was also thoroughly encouraged to use the prescribed antiretroviral medication correctly. Conclusion: Dermatophytosis in patients living with human immunodeficiency virus can present extensive and disseminated forms. The antifungal treatment is quite effective, with remission of the condition. Antiretroviral therapy is an important adjuvant for better recovery of the sickness.

Introdução: Dermatofitoses são infecções comuns, causadas pelas espécies fúngicas Microsporum, Epidermophyton ou Trichophyton, que acometem preferencialmente a pele da região interdigital, da virilha e do couro cabeludo. Apesar de não causar doenças graves, em pacientes portadores do vírus da imunodeficiência humana, a infecção se manifesta e evolui de forma exuberante, normalmente com lesões extensas e disseminadas. Objetivo: Fazer revisão de literatura sobre dermatofitose em pessoas vivendo com vírus da imunodeficiência humana e apresentar a experiência na atenção clínica em uma paciente vivendo com o vírus e dermatofitose extensa e disseminada. Métodos: A revisão de literatura sobre o tema baseou-se nos dados do Pubmed/National Library of Medicine, dos Estados Unidos, utilizando-se as palavras-chave dermatofitose, dermatofitose e AIDS, dermatofitose e vírus da imunodeficiência humana, e dermatofitose e imunodeficiência, de 1988­2022. Descreveu-se a experiência clínica na abordagem de uma paciente vivendo com vírus da imunodeficiência humana, a qual desenvolveu AIDS e apresentou lesões cutâneas disseminadas. Por raspado, foram coletadas amostras da lesão e submetidas à cultura, e constatou-se crescimento de fungos do gênero Trichophyton sp. Realizou-se também biópsia da lesão, corada pelo método da metenamina de prata de Grocott-Gomori. Resultados: Foram encontrados 1.014 artigos, dos quais apenas 34 apresentaram correlação direta com nosso trabalho, e foram utilizados para discorrer sobre os principais temas narrados neste artigo. Apresentou-se experiência clínica na abordagem de uma paciente com vírus da imunodeficiência humana/AIDS e baixa adesão ao tratamento antirretroviral, exibindo lacerações eritematoescamosas extensas e disseminadas, com diagnóstico clínico de Tinea corporis, manifestando-se com quadro clínico usualmente não encontrado em pacientes imunocompetentes. O diagnóstico foi confirmado por exames laboratoriais com isolamento do fungo Trichophyton sp. Tratada com fluconazol via oral, a paciente apresentou remissão parcial das infecções aos dois meses e completa aos seis meses. Também foi exaustivamente estimulada a usar corretamente a medicação antirretroviral prescrita. Conclusão: A dermatofitose em pacientes com vírus da imunodeficiência humana pode se apresentar de forma extensa e disseminada. O tratamento antifúngico é eficaz, com remissão do quadro. A terapia antirretroviral é importante adjuvante para melhor recuperação dos enfermos

Online teaching, quality of life and anxiety of Brazilian dental professors during the COVID-19 outbreak

Abstract: The COVID-19 pandemic led to changes in academic teaching and dental education, but the impact on dental professors' mental health and quality of life remains poorly understood. Thus, the objective of this study was to evaluate the impacts of social distancing and online teaching related to COVID-19 on the quality of life and anxiety of Brazilian dental professors. This was a cross-sectional study conducted from August 2020 to October 2020. Three instruments were used in an online version: a questionnaire about personal data, academic information and online teaching activities, the Generalized Anxiety Disorders 7 (GAD7) scale, and the Abbreviated World Health Organization Quality of Life (WHOQOL-bref) scale. All instruments were sent by e-mail, social media, and messaging apps to private and public universities and professors. Of the 318 responses, 187 (58.8%) were from female professors. Moreover, lack of good internet access and adequate place for online teaching, difficulties in producing teaching materials, and housework roles had a significant impact on the quality of life and anxiety scores (all p-values < 0.05). Also, Brazilian dental professors who declared that they would make greater efforts if the activities were face-to-face had significantly worse quality of life and anxiety scores, and female professors had significantly higher anxiety scores (all p-values < 0.05). These results provide evidence of a negative effect of social distancing and online teaching activities related to COVID-19 outbreak on the health-related quality of life and mental health of Brazilian dental professors.
