Aim This study aimed to assess the polymerization effectiveness of bulk-fill composite resins in longitudinal microhardness. Methods Blocks of bulk-fill composite resin with thicknesses of 6 mm were analyzed with Vickers microhardness. The resin blocks were divided into two groups (n=6): resin AURA and OPUS. The microhardness test was performed before (base and top) and after (longitudinal microhardness) sectioning the blocks at distances of 2 mm, 4 mm, and 6 mm from the top of the block. The mean microhardness values were tabulated and subjected to ANOVA followed by Tukey’s test (p<0.05). Results The OPUS bulk-fill resin samples presented microhardness means of 55.9 kgf/mm2, 53.7 kgf/mm2, and 49.3 kgf/mm2, the AURA bulk-fill resin samples presented microhardness means of 57,02 kgf/mm2, 55,86 kgf/mm2 e 51,77 kgf/mm2 for the distances of 2 mm, 4 mm, and 6 mm, respectively. Tukey’s statistical test showed a significant difference in microhardness values at different distances of 2 mm, 4 mm, and 6 mm (p<0.001) for each resin. Although there was a statistically significant difference within and between the groups assessed, all samples showed polymerization effectiveness when comparing the top and base of the block. Conclusion Polymerization was effective in different thicknesses (2 mm, 4 mm, and 6 mm) in both resins studied. The microhardness ratio was adequate when comparing the base and top. bulkfill bulk fill n=6 n6 n (n=6) block Tukeys Tukey s p<0.05. p005 p p<0.05 . 0 05 (p<0.05) 559 55 9 55. kgfmm2 kgfmm kgf mm2 537 53 7 53. 493 49 3 49. 5702 57 02 57,0 5586 86 55,8 kgf/mm 5177 51 77 51,7 respectively p<0.001 p0001 001 (p<0.001 assessed ( studied n= (n=6 p00 p<0.0 (p<0.05 5 570 57, 558 8 55, 517 51, p<0.00 p000 00 (p<0.00 (n= p0 p<0.

ABSTRACT Objective: To describe the trend in incidence, mortality and Disability Adjusted Life Years of oral cancer in Latin America according to sex between 2000 and 2020. Methods: This ecological study extracted oral cancer information from 20 Latin American countries from the GBD-2020 database. Oral cancer burden was described by age-standardized rate (ASR) of incidence, mortality, and DALYs. The data was compared according to sex and countries. Trends (Average Annual Percentage Change-AAPC) were estimated for each indicator, sex, and country between 2000 and 2020 using Joint-point software. Results: Between 2000 and 2020, the highest incidence of oral cancer (ASR) occurred in Cuba (5.18), Brazil (4.38) and Uruguay (4.62). The countries with the highest mortality for both sexes were (ASR): Cuba (2.89), Brazil (2.71) and the Dominican Republic (2.58). The DALYs registered an average of 37.52 (Women: 22.39; Men: 52.62). The Dominican Republic reports increasing trends in incidence (AAPC: Men: 2.2; Women: 1.4), in mortality (AAPC: Men: 1.8; Women: 1.1), and in DALYs (AAPC: Men: 1.0; Women: 2.0). Costa Rica shows decreasing trends in men in incidence (AAPC: −1.3), mortality (AAPC: −1.6), and DALYs (AAPC: −1.8). Conclusion: Oral cancer shows increasing trends in: the incidence in both sexes in 10 countries, in mortality and DALYs in 6 countries, while the affectation between sexes does not show differences in trends.

Abstract Objective: To assess the level of satisfaction and quality of life (QOL) of caregivers of Patients with Special Needs seen at the Dental Specialties Center in Aracaju, Brazil. Material and Methods: The Program for Primary Care Access and Quality Improvement (PMAQ – DSC) and the World Health Organization's Quality of Life - Brief (WHOQOL-BREF) questionnaires were applied to PSN and caregivers. Results: The PMAQ questionnaire was applied to 31 patients or caregivers; 97% had no paid work and 61% used public transportation to reach the Dental Specialties Center. The WHOQOL-BREF questionnaire was applied to 20 caregivers; 60% considered their life to be good; however, 60% had practically no leisure time. Correlation tests (Pearson’s coefficient) showed a statistically significant correlation between the physical and psychological domain (p=0.02; r=0.64), the psychological and social domain (p=0.033; r=0.48), and the psychological and environment domain (p<0.001; r=0.80). Conclusion: The caregivers and patients with special needs felt satisfied with the specialized oral health service offered by the municipality. Concerning the quality of life of caregivers, the majority stated they had a good quality of life, despite not having the opportunity to participate in leisure-oriented activities and often having negative feelings.

ABSTRACT Introduction: due to the increase in life expectancy and, consequently, to the increase in the number of elderly people, the association between health states becomes relevant in terms of public health, since in addition to the lived years the quality of life of these patients is important. Objective: evaluate the self-perception of oral health and check the oral health condition of the elderly. Methods: observational cross-sectional study (January to July / 2019) in which questionnaires were the GOHAI (Geriatric Oral Health Assessment Index) questionnaire and questionnaire about type, time of use and cleaning of dental prostheses, oral cancer and socioeconomic data. The presence of possible oral lesions was also assessed by clinical examination. The subjects included in the sample were elderly (60 years or older) attending the Aracaju Health Units. Results: fifty-five were female and eight male. When evaluating the Geriatric Oral Health Assessment Index, it is verified that 47.6% of the sample has poor self-perception of oral health. Associations were found between GOHAI Index for last visit to the dentist, dental prosthesis adaptation and mouth wound (p < 0.05). The most prevalent oral lesions were reddish or irritated mucosa (35.7 %), followed by erythroplakia (14.2 %), 76% of the prostheses had cracks or dirt. About the cleaning of the protests, 77.7 % use only dentifrice as cleaning material. Conclusion: self-perceived oral health and oral health conditions of the elderly evaluated were considered poor, in the presence of poorly adapted and cracked prostheses, in addition to mucositis.

RESUMEN Introducción: Debido al aumento en la esperanza de vida y, en consecuencia, al aumento en el número de personas mayores, la asociación entre los estados de salud se vuelve relevante en términos de salud pública, ya que además de los años vividos, la calidad de vida de estos pacientes es importante. Objetivo: Evaluar la autopercepción y el estado de salud bucal en personas mayores. Métodos: Estudio observacional, de corte transversal (enero-julio del 2019) en el que se realizaron cuestionarios GOHAI (índice de evaluación de la salud oral geriátrica) y el cuestionario sobre el tipo, el tiempo de uso y la limpieza de las prótesis dentales, el cáncer oral y los datos socioeconómicos. La presencia de posibles lesiones orales también se evaluó mediante examen clínico. Los sujetos incluidos en la muestra eran ancianos (60 años o más) que asistían a las unidades de salud de Aracaju. Resultados: Participaron 55 mujeres y ocho hombres. Al evaluar el índice de evaluación de la salud oral geriátrica, se verificó que el 47,6 % de la muestra tenía una mala percepción de la salud oral. Se encontraron asociaciones entre el índice de evaluación de la salud oral geriátrica entre la última visita al dentista, la adaptación de la prótesis dental y las heridas bucales (p < 0,05). Las lesiones orales más prevalentes fueron mucosa rojiza o irritada (35,7 %) y eritroplasia (14,2 %) y se detectó que el 76 % de las prótesis tenían grietas o suciedad. El 77,7 % de los participantes en el estudio solo utilizaban dentífrico como material de limpieza de la prótesis. Conclusión: La salud bucal autopercibida y las condiciones de salud bucal de los ancianos evaluados se consideraron deficientes, se observa la presencia de prótesis mal adaptadas y agrietadas, además de mucositis.

Resumo O objetivo deste artigo é relatar o caso clínico de um menino de 3 anos e 7 meses de idade com microcefalia com múltiplos cistos de erupção e discutir as condutas adotadas. Baseadas nos aspetos clínicos e radiográficos, o diagnóstico foi de cisto de erupção. Para o tratamento optou-se pela incisão cirúrgica dos cistos de erupção, sob anestesia geral, mas por motivos de saúde o paciente não pode realizar o procedimento proposto e, após 4 meses, sete dos oito cistos de erupção tinham desaparecidos com a irrupção dos molares decíduos, sem necessidade de intervenção cirúrgica. No que diz respeito ao cisto de erupção remanescente a terapêutica eleita foi o acompanhamento e descompressão manual realizada pela mãe. É possível individualizar o tratamento do cisto de erupção optando-se pelo acompanhamento da lesão com o desaparecimento espontâneo da mesma, sem qualquer tipo de intervenção.

Abstract The aim of this paper is to report the clinical case of a 3-year and 7-month-old male child with microcephaly who had multiple eruption cysts, and to discuss the adopted procedures. The diagnosis of eruption cyst was concluded based on the clinical and radiographic characteristics. The treatment proposed was a surgical incision of the eruption cysts with the patient under general anesthesia. However, due to health reasons, the patient could not have the procedure performed, and, after four months, seven of the eight eruption cysts had regressed with teeth eruption; therefore, no surgical intervention was needed. Regarding the remaining eruption cyst, the therapy adopted was his mother monitoring the condition. It is possible to personalize eruption cyst treatment by monitoring the lesion until its eventual spontaneous disappearance, without any type of intervention.

ABSTRACT Background: Mortality from oral cancer, the prevalence of the main risk factors and the implementation of policies to control current trends and the distribution of data among the countries of Latin America. The objective of this study was to describe the trends of mortality from oral cancer between 2000 and 2017, by sex, in 20 countries in Latin America, and to know the effect of measures to control tobacco consumption and alcohol consumption on the Mortality from oral cancer. Methods: Ecological study that evaluates the relationship between the rates standardized by the age of cancer by oral sex, the prevalence of tobacco consumption and alcohol consumption, and the implementation of control policies. To calculate the annual percentage change of the rates, the Prais-Winsten regression was used; and the effect of measures of control of risk factors on oral cancer mortality is assessed by Spearman correlations. Results: The greatest decreases in oral cancer mortality were in men in Brazil (APC -7.83, -14.25, -0.93). Mortality from cancer the oral relationship between men and the prevalence of tobacco consumption and alcohol consumption (r = 0.358, r = 0.537) (p <0.01), and between the non-implementation of control policies of smoking (r = 0.738) (p = 0.003), the restrictions on the hours and days of sale of alcohol (r = 0.777, p = 0.001), and the states on sponsorship and promotion of alcohol sales (r = 0.739 , p = 0.040). Conclusions: The effect of the implementation of control policies is evidenced by a greater relationship with oral cancer mortality in the countries with the least progress in their execution.

Objective: To compare estimates of food behavior related to oral health obtained through a self-report measure and 24 hour dietary recalls (R24h). Method: We applied three R24h and one self-report measure in 87 adolescents. The estimates for eleven food items were compared at individual and group levels. Results: No significant differences in mean values were found for ice cream, vegetables and biscuits without filling. For the remaining items, the values reported by the adolescents were higher than the values estimated by R24h. The percentage of adolescents who reported intake frequency of 1 or more times/ day was higher than the value obtained through R24h for all food items except soft drinks. The highest values of crude agreement between the instruments, individually, were found in the biscuits without filling (75.9%) and ice cream (72.4%). Conclusion: The results suggest that adolescents tend to report a degree of exposure to the food items larger than what they actually experience in their daily lives.

AIM: To evaluate caries experience and associated factors in 5-year-old preschool children in the city of Indaiatuba, SP, Brazil. METHODS: This was a cross-sectional, representative study, conducted from an epidemiological oral health survey (2010) with 303 children. The sample was established by the systematic probabilistic method, in public and private schools, in accordance with WHO criteria. The sample was checked for caries experience (dmft) by four trained and calibrated dentists, reaching acceptable levels of agreement for data collection. Parents or guardians answered questions related to their education and monthly income, and the children answered questions related to dental care and pain. Descriptive and bivariate analyses of independent variables were performed. Variables with p<0.20 were included in the model (Poisson regression analysis). RESULTS: The sample consisted of 151 boys and 152 girls, with a mean dmft of 1.46. The reasons for visiting a dentist due to pain or need for treatment were associated with dmft > 0 (PR=3.76, 95%CI=2.06-6.84) after adjustment of the regression model. CONCLUSIONS: Among the preschool children of this study, pain or need for treatment due to caries disease in the primary dentition and the reason to visit the dentist due pain emphasizing the importance of the professional not only in curative actions, but as a health promoter at the first contact with the child.

Conventional tilted implants are used in oral rehabilitation for heavily absorbed maxilla to avoid bone grafts; however, few research studies evaluate the biomechanical behavior when different angulations of the implants are used. The aim of this study was evaluate, trough photoelastic method, two different angulations and length of the cantilever in fixed implant-supported maxillary complete dentures. Two groups were evaluated: G15 (distal tilted implants 15°) and G35 (distal tilted implants 35°) n = 6. For each model, 2 distal tilted implants (3.5 x 15 mm long cylindrical cone) and 2 parallel tilted implants in the anterior region (3.5 x 10 mm) were installed. Photoelastic models were submitted to three vertical load tests: in the end of cantilever, in the last pillar and in the all pillars at the same time. We obtained the shear stress by Fringes software and found values for total, cervical and apical stress. The quantitative analysis was performed using the Student tests and Mann-Whitney test; p ≥ 0.05. There is no difference between G15 and G35 for total stress regardless of load type. Analyzing the apical region, G35 reduced strain values considering the distal loads (in the cantilever p = 0.03 and in the last pillar p = 0.02), without increasing the stress level in the cervical region. Considering the load in all pillars, G35 showed higher stress concentration in the cervical region (p = 0.04). For distal loads, G15 showed increase of tension in the apical region, while for load in all pillars, G35 inclination increases stress values in the cervical region.
