Effects of polymethyl methacrylate-based bone cement graft for treating excessive gingival display and its dimensional facial changes: 12-Month clinical study.

Objective: to present a 12-month follow-up with photographic and tomographic analyses of the effect of polymethyl methacrylate-based bone cement graft (PMMA) in gingival exposure (GE) in patients with excessive gingival display (EGD). Methods: Twelve patients with EGD were included. The PMMA was surgically placed. A frontal and lateral photograph protocol was performed at baseline (T0), 3 (T3), 6 (T6), and 12 months (T12) post-operatively. Soft tissue cone-beam computed tomography (ST-CBCT) was performed at T0 and T12. Measures included GE, length of the lip vermilion (LLV), lip shape (LS), nose width (NW), filter width (FW), nasolabial angle (NAS) while smiling, and nasolabial angle at rest (NAR). The height, thickness, and volume of the cement graft were also measured in the ST-CBCT. The comparisons were performed by Kruskal-Wallis test at 5 % of significance (p < 0.05). Results: The height, thickness, and volume of the PMMA were respectively 12.84 ± 1.59 mm, 3.83 ± 0.53, and 1532.02 ± 532.52 mm3. PMMA significantly decreased GE from 8.33 ± 1.25 mm (T0) to 6.60 ± 0.93 mm (T12) (p < 0.01). NAR was 98.34 ± 9.28° at T0 and increased to 105.13 ± 7.33° at T12; however, the angle value was not statistically different (p = 0.08). LLV, LS, NW, FW, and NAS did not exhibit statistical differences between the baseline and follow-up periods. Conclusions: PMMA significantly decreased GE in a 12-month follow-up without influencing adjacent soft tissue anatomical structures.

Dental and periodontal dimensions stability after esthetic clinical crown lengthening surgery: a 12-month clinical study.

OBJECTIVES: To evaluate the stability of periodontal tissues 3 (T3), 6 (T6), and 12 (T12) months after esthetic crown lengthening (ACL) and the possible correlations between changes in those structures. MATERIALS AND METHODS: Twenty individuals were evaluated through clinical assessment, photography, and tomography. Measurements included gingival margin (GM), clinical crown length (CCL), interdental papilla height (PH) and width (PW), gingival thickness (GT), bone thickness (BT), probing depth (PD), distance between alveolar crest and GM, distance between alveolar crest and cementoenamel junction. Nonparametric and correlation statistics were performed (p < 0.05). RESULTS: CCL at T0 was 7.42 ± 0.70 mm and increased to 9.48 ± 0.49 mm immediately after ACL, but it decreased to 8.93 ± 0.65 mm at T12. PD decreased 0.60 mm from T0 to T6, and it increased 0.39 mm from T6 to T12. BT decreased 0.20 mm, while GT increased 0.29 mm from T0 to T12. Both PW and PH showed enlargement in T12. A positive moderate correlation was found between CCL/T0 and CCL/T12, GT/T0 and AC-GM/T12, BT/T0 and GT/T12. A few negative moderate correlations were PD/T0 and CCL/T12, PD/T0 and PH/T0, PD/T0 and BT/T12. CONCLUSIONS: ACL procedure was effective. Although some rebound occurred, that was not clinically important. PD tended to reestablish its original length, partially due to a migration of GM during the healing period. Besides, a thickening of supracrestal soft tissues was observed. CLINICAL RELEVANCE: The present study centers on the factors influencing the stability of periodontal tissues after esthetic crown lengthening, underscoring the procedure's influence on esthetics and biology and the need for careful treatment planning.

Does using the sociodental approach in oral health care influence use of dental services and oral health of adolescents living in deprived communities? a one-year follow up study.

BACKGROUND: Oral health needs assessment is important for oral health care planning. This study compared dental treatment needs between normative and sociodental needs. We also longitudinally examined the relationships of baseline sociodental needs measures and socioeconomic status with one-year follow up measures of use of dental services, dental caries, filled teeth, and oral health-related quality of life (OHRQoL). METHODS: A prospective study was conducted with 12-year-old adolescents from public schools in deprived communities in the city of Manaus, Brazil. Validated questionnaires were used to collect adolescents' sex and socioeconomic status, OHRQoL (CPQ11 - 14) and behaviours (sugar intake, frequency of toothbrushing, regular use of fluoridated toothpaste and pattern of dental attendance). Normative need was assessed according to decayed teeth, clinical consequences of untreated dental caries, malocclusion, dental trauma, and dental calculus. The relationships between variables were tested thorough Structural equation modelling. RESULTS: Overall 95.5% of adolescents had normative dental treatment needs. Of these, 9.4% were classified as high level of propensity. Higher normative/impact need and greater propensity-related need directly predicted use of dental services at one-year follow up. The latter mediated the association of normative/impact need and propensity-related need with incidence of dental caries and filled teeth. Normative/impact need and use of dental services were directly associated with filled teeth at one-year follow up. Poor OHRQoL at one-year follow-up was directly predicted by higher normative/impact need at baseline and less filled teeth at one-year follow up. Greater socioeconomic status was directly associated with better propensity-related need. Socioeconomic status indirectly predicted incidence of dental caries and filled teeth via propensity-related need and use of dental services. CONCLUSIONS: Sociodental needs measures were related to use of dental services, dental caries, filled teeth and OHRQoL after one year among adolescents living in deprived communities. Adolescents with dental needs treatment priorities according to the sociodental approach had more filled teeth via use of dental services. Dental services utilisation did not attenuate the impact of normative and impact-related need on dental caries incidence and poor OHRQoL after one year. Our findings suggest the importance of developing oral health promotion and enhancing access to dental care to improve oral health of adolescents living in deprived communities.

Cationic dialdehyde cellulose microfibers for efficient removal of eriochrome black T from aqueous solution.

Materials based on cellulose have been widely used as a decontaminant agent of wastewater. However, it can not be found in the literature any application of the cationic dialdehyde cellulose (cDAC) in anionic dye removal. Therefore, this study aims a circular economy concept using sugarcane bagasse to obtain a functionalized cellulose by oxidation and cationization. cDAC was characterized by SEM, FT-IR, oxidation degree, and DSC. Adsorption capacity was evaluated by pH, kinetic, concentration effect, strength ionic tests, and recycling. The kinetic followed Elovich model (R2 = 0.92605 for EBT = 100 mg/L) and non-linear Langmuir model (R2 = 0.94542), which resulted in a maximum adsorption capacity of 563.30 mg/g. The cellulose adsorbent reached an efficient recyclability of 4 cycles. Thus, this work presents a potential material to become a new, clean, low-cost, recyclable, and environmentally friendly alternative for effluent decontamination-containing dyes.

Dynapenic abdominal obesity is related to cardiovascular risk in older adults with Parkinson's disease: A cross sectional study.

BACKGROUND AND AIMS: Currently, the impact of nutritional status in Parkinson's disease over the cardiovascular risk is poorly understood. Thus, this study aimed to evaluate dynapenic abdominal obesity and its influence in anthropometric parameters of cardiovascular risk in older patients with Parkinson's disease. METHODS: This is a cross-sectional study involving outpatients diagnosed with Parkinson's disease in two treatment centers in northeast of Brazil. We included patients who aged 60 years and older. The data was collected from January to July of 2019. For abdominal obesity, waist circumference was used. For dynapenia, Handgrip Strength was measured. Dynapenic abdominal obesity was established as the coexistence of dynapenia and abdominal obesity. RESULTS: The dynapenic abdominal obesity occurred in 25% of the patients and was higher in women (p = 0.073). The dynapenic abdominal obesity group had a decreased muscle strength, higher values of Body Mass Index, a worse Waist Height Ratio; increased values of Fat Mass and percentual of Fat Mass and an increased value of Conicity Index (p < 0,05). CONCLUSION: The occurrence of dynapenic abdominal obesity in our population was related to the worsening of anthropometric values of cardiovascular risk. From our results we can suggest that the early identification of the coexistence of nutritional disorders, such as dynapenia and abdominal obesity can help in the appropriate intervention to mitigate the risks related to adverse events.

Parents' sense of coherence in the use of dental services by children aged 12 years old in the city Manaus/AM

Aim The aim of this study was to evaluate the association between the sense of coherence (SOC) of parents/guardians and the use of dental services by children who are 12 years old. Methods This is a cross-sectional study conducted in the eastern zone of the city of Manaus, with 358 children enrolled in the 7th grade in the municipal public school system. Data collection was performed through self-administered questionnaires sent to parents/guardians, which contained questions about socioeconomic conditions, use of dental services by children and Antonovsky's SOC-13 scale. Data were examined by descriptive and bivariate analysis, using the Chi-square test, with a 5% significance level. Results Of the 358 children, 58.4% were female; in addition, 75.4% of the parents/guardians self-reported to be brown and 39.9% of them had a family income of ½ to 1 minimum wage. SOC was categorized as strong SOC and weak SOC by the median. The association between strong or weak SOC and the use of dental services in terms of frequency (p= 0.839) and reason for last visit (p= 0.384), was not significant. Conclusion It was concluded that SOC of parents/guardians and utilization of dental services by children were not associated.

Virtual hepatectomy and metastasectomy 3D simulation using an automated and semiautomated tool applied to preoperative CT in the treatment of colorectal cancer metastases.

Colorectal cancer represents the most common malignancy of the gastrointestinal tract and the second most frequently diagnosed malignancy in adults. The most common site of metastases is the liver and 40% of patients in stage IV have liver only disease.1 Hepatic metastases are the major determinants of morbidity and mortality in these patients, with surgery being the treatment of choice or even curative in these cases.2 Therefore, aggressive surgeries should be considered in patients with liver only disease. In this context, hepatectomy and metastasectomy have emerged as promising techniques for improving survival in patients with metastatic disease, also providing long-term cure.3 The use of liver volumetrics, tridimensional reconstructions with vessel extraction and 3D virtual surgery simulations allows better surgical planning and potentially decrease transfusions, surgery time and complications.4 For major hepatectomies (>4 resected segments), surgical planning with computed angiotomography and liver remnant volume calculation potentially increases the safety of surgery. We report a case in which preoperative 3D surgical simulation was crucial for conducting a safe major hepatectomy in a patient with multiple colorectal liver metastases.

FAST breast magnetic resonance imaging: a new approach for breast cancer screening?

OBJECTIVE: To develop an abbreviated breast magnetic resonance imaging protocol (FAST) and to compare it with the complete protocol (FULL) to determine its diagnostic accuracy for detecting malignant or suspicious lesions (BI-RADS 4, 5 and 6) and the time required for image interpretation using BI-RADS categorization. METHODS: Retrospective study with 100 consecutive women who underwent breast magnetic resonance imaging between January and February 2014. All patients were submitted to a complete breast magnetic resonance imaging protocol, which was then compared with an abbreviated protocol (pre-contrast sequence, second post-contrast sequence and subtraction of pre- from post-contrast images). RESULTS: Of 100 patients, 4 were classified as BI-RADS 5 or 6 and 16 as BI-RADS 4. In these 20 patients, there was full agreement among readers regarding the final BI-RADS categorization in both (FAST and FULL) protocols. CONCLUSION: The FAST protocol reduces interpretation time without compromising the accuracy of the method for detection of malignant or suspicious lesions.

Phase angle, muscle mass, and functionality in patients with Parkinson's disease.

OBJECTIVE: To evaluate the association of phase angle (PA) with clinical and nutritional aspects in patients with Parkinson's disease (PD) treated in an outpatient clinic in northeastern Brazil. METHODS: This is a case series study involving adults and the elderly with PD of both genders. We collected data such as stage, severity, and time of diagnosis of the disease, muscle strength, gait speed, and level of physical activity. We evaluated the nutritional status using body mass index, calf circumference, skeletal appendicular muscle mass index, and the presence of sarcopenia. We obtained the PA through the analysis by electrical bioimpedance. After obtaining the result of the division between reactance and resistance, with later transformation into degrees, we multiplied the result by 180/π. RESULTS: We evaluated 77 individuals with a mean age of 65.4 ± 8.9 years. 63.6% of them had reduced PA values and 19.7% of them had sarcopenia. Age (rho = - 0.423; p = < 0.001) was inversely correlated with PA. Skeletal appendicular muscle mass index (rho = 0.251; p = 0.028), pressure force (rho = 0.240; p = 0.035), and gait speed (rho = 0.323; p = 0.005) showed a direct correlation with age. When adjusted for confounding factors, only age remained associated with PA (p = 0.012). CONCLUSION: Most individuals had reduced PA, and only age was associated with this result. Aging is a risk factor for reducing muscle mass and physical disability in PD. Although this study indicates a relationship between PA, age, muscle mass, and functionality, further prospective studies are needed to confirm these findings.

In vivo assessment of antioxidant, antigenotoxic, and antimutagenic effects of bark ethanolic extract from Spondias purpurea L.

Medicinal plants have always been used for therapeutic purposes; however, some plants may contain toxic and mutagenic substances. The aim of this study was to assess the cytotoxic, genotoxic, mutagenic, antioxidant, antigenotoxic, and antimutagenic effects of the bark ethanolic extract of Spondias purpurea L. using male and female Swiss albino mice. To determine the protective effects of the extract, benzo[a]pyrene (B[a]P) and cyclophosphamide (CP) were selected as cell damage inducers. The extract was examined at doses of 500, 1000, or 1500 mg/kg body weight (BW)via gavage alone or concomitant with B[a]P or CP. Oxidative stress was measured by quantification of blood catalase activity (CAT), reduced glutathione (GSH) levels in total blood, liver, and kidney, and concentrations of malondiadehyde (MDA) in liver and kidney. Genotoxicity and antigenotoxicity were evaluated by the comet assay using peripheral blood. Cytotoxicity, mutagenicity, and antimutagenicity were determined utilizing the micronucleus test in bone marrow and peripheral blood. The S. purpurea L extract increased CAT activity and GSH levels accompanied by a decrease in MDA levels after treatment with B[a]P and CP. No genotoxic, cytotoxic, or mutagenic effects were found in mice exposed only to the extract. These results indicate that the extract of S. purpurea exhibited protective effects against oxidative and DNA damage induced by B[a]P and CP.

Fluoride Concentration in Public Water Supply in a City in the Amazon Region

Abstract Objective: To analyze the fluoride concentration in the public water supply in Manaus, Brazil. Material and Methods: Water samples were collected in 50 mL polyethylene bottles, identified, and labeled. The collection was performed from September 2016 to August 2018. For the selection of collection points, all neighborhoods of the city of Manaus, divided into four health districts (North, South, East, and West), were mapped. From each district, 30 samples were collected, totaling 120 monthly samples. Water samples were analyzed using an ion analyzer, ORION 720-A, and a specific electrode, ORION 96-09. The ion analyzer and electrode were calibrated in standard solutions. The levels were classified in intervals based on technical consensus to guide the health surveillance agencies. Results: Of the 2,874 water samples, 50.3% were within the recommended range, and 49.7% were inadequate, with 31.6% considered above the parameters and 18.1% below. Among the districts, the North had the highest percentages of unsatisfactory samples, resulting in limited action to prevent tooth decay. During the 24 months of analysis, there were large oscillations in the values in all four districts of Manaus. Conclusion: Results reinforce the importance of heterocontrol for the city to guarantee the effectiveness of this public health measure.

Prevalence and factors associated with maternal breastfeeding in the first hour of life in full-term live births in southwest Bahia, Brazil, 2017. / Prevalência e fatores associados ao aleitamento materno na primeira hora de vida em nascidos vivos a termo no sudoeste da Bahia, 2017.

OBJECTIVE: to analyze prevalence and factors associated with maternal breastfeeding in the first hour of life (MBFFHL) in full-term live births in Vitória da Conquista, BA, Brazil. METHODS: this was a cohort-nested cross-sectional study; data were collected between February and August 2017 using a questionnaire answered by mothers as well as medical records; hierarchical multivariable analysis with Poisson regression was used. RESULTS: the study included 388 mother-liveborn baby pairs; MBFFHL prevalence was 49.5%; outcome was associated with maternal education ≥12 years (PR=0.63 - 95%CI 0.46;0.87), prenatal guidance on child holding and positioning (PR=1.44 - 95%CI 1.07;1.95), liveborn baby taken to its mother soon after delivery (PR=1.41 - 95%CI 1.04;1.92), mother and baby kept together in the same room (PR=2.42 - 95%CI 1.09;5.36), and delivery at a Baby-Friendly Hospital (PR=2.43 - 95%CI 1.72;3.43). CONCLUSION: MBFFHL was associated with maternal factors, prenatal care and hospital care.

Socioeconomic status, social support, oral health beliefs, psychosocial factors, health behaviours and health-related quality of life in adolescents.

PURPOSE: This study assessed the relationships between socioecononic status (SES), social support, oral health beliefs, psychosocial factors, health-related behaviours and health-related quality of life (HRQoL) in adolescents. METHODS: A school-based follow-up study involving 376 12-year-old adolescents was conducted in Manaus, Brazil. Baseline data included sociodemographic characteristics (sex, parental schooling, family income, household overcrowding and number of goods), social support (SSA questionnaire), oral health beliefs and psychosocial factors (Sense of Coherence [SOC-13 scale] and self-esteem [Rosenberg Self-Esteem Scale]). Health-related behaviours (toothbrushing frequency, sedentary behaviour, smoking and sugar consumption) and HRQoL [KINDL questionnaire] were assessed at 6-month follow-up. Structural Equation Modelling assessed the relationships between variables. RESULTS: Greater social support (ß = 0.30), higher SOC (ß = 0.23), higher self-esteem (ß = 0.23), higher toothbrushing frequency (ß = 0.14) and less smoking (ß = - 0.14) were directly linked with better HRQoL. SES (ß = 0.05), social support (ß = 0.26), oral health beliefs (ß = - 0.02) were indirectly linked to HRQoL. Higher SES directly predicted higher toothbrushing frequency (ß = 0.14) and less smoking (ß = - 0.22). Greater social support also directly predicted higher SOC (ß = 0.55), positive oral health beliefs (ß = - 0.31) and higher self-esteem (ß = 0.58). Greater social support indirectly predicted less smoking via oral health beliefs (ß = - 0.05) and less sugar consumption via SOC (ß = - 0.07). CONCLUSION: Socioeconomic status, social support, oral health beliefs and psychosocial factors were important predictors of adolescent's health behaviours and HRQoL over 6-month period through direct and indirect mechanisms. Health behaviours also directly influenced HRQoL.

Prevalence and factors associated with tea consumption in the first month of life in a birth cohort in the Northeast Region of Brazil / Prevalência e fatores associados ao uso de chá no primeiro mês de vida em uma coorte de nascimento na Região Nordeste do Brasil

Abstract Objectives: to determine the prevalence and analyze the factors associated with newborns drinking tea in a birth cohort. Methods: A cross-sectional study with nested prospective cohort was conduct with 329 puerperal women and their newborns in Vitória da Conquista, Bahia. Sociodemographic and information about the newborn's diet and mothers/babies was obtained at a maternity and 30 days after birth, at home visits. The prevalence ratios (PR) and its respective confidence intervals (CI95%) were estimated with Poisson regression models according to the hierarchical conceptual model. Results: the prevalence of tea consumption up to 30 days of life was 34.6% (CI95%=29.7; 40.0%). The sociodemographic and maternal characteristics associated with the outcome were not having a partner (PR = 1.39; CI95%=1.03-1.88), more than eight years of schooling (PR=1.38; CI95%=1.03-1.84), lower income (PR=2.21; CI95%=1.31-3.73), primiparous (PR=1.48; CI95%=1.01-2.17) and does not have any experience with breastfeeding before (PR=2.25; CI95%=1.48-3.41). As for the child, there was a higher prevalence of tea consumption than among those who received artificial milk in the first month of life (PR= 2.10; CI95%=1.62-2.73). Conclusions: the offer of tea in the first month of life was high. Tea consumption was positively associated with sociodemographic, maternal and newborn feeding factors.

Results: the study included 388 mother-liveborn baby pairs; MBFFHL prevalence was 49.5%; outcome was associated with maternal education ≥12 years (PR=0.63 - 95%CI 0.46;0.87), prenatal guidance on child holding and positioning (PR=1.44 - 95%CI 1.07;1.95), liveborn baby taken to its mother soon after delivery (PR=1.41 - 95%CI 1.04;1.92), mother and baby kept together in the same room (PR=2.42 - 95%CI 1.09;5.36), and delivery at a Baby-Friendly Hospital (PR=2.43 - 95%CI 1.72;3.43). Conclusion: MBFFHL was associated with maternal factors, prenatal care and hospital care.

Prevalence evaluation of apical periodontitis and its relationship with endodontic and restorative treatment in a community in Southern Brazil / Avaliação da prevalência de periodontite apical e sua relação com o tratamento endodôntico e restaurador em uma comunidade no sul do Brasil

Objetivo: O objetivo deste estudo foi avaliar a prevalência de periodontite apical (PA) em dentes tratados endodonticamente (DTE) e relacioná-la com fatores demográficos, qualidade dos tratamentos endodônticos e restaurações. Material e método: Foram coletados dados de prontuários odontológicos de pacientes que continham levantamentos radiográficos periapicais completos. Nos DTE, arco, grupo dental e presença de PA foram avaliados. Dados sobre a qualidade da obturação do canal radicular, a presença e a qualidade da restauração e o tipo de material restaurador também foram coletados. Os dados foram avaliados por estatística descritiva e Teste Qui-quadrado. Resultados: Dos 70 pacientes incluídos na amostra final, a maioria era do sexo feminino (54,3%) e a idade variou de 13 a 77 anos (47,14 ± 13,18). Dos 1333 dentes avaliados, 73 (5,4%) tinham tratamento endodôntico, sendo a maioria em dentes superiores (74%) e anteriores (52,1%). Dos dentes sem tratamento endodôntico, 320 (25,4%) apresentavam PA. A taxa de falha foi alta (52,8%) e a qualidade da obturação do canal radicular e da restauração foram consideradas inadequadas na maioria dos casos (58,3% e 47,7%, respectivamente). O grupo dentário apresentou relação estatisticamente significante com a presença de PA em DTE, sendo mais frequente nos dentes anteriores (p = 0,019). Conclusão: Concluiu-se que a prevalência de PA em DTE foi alta e o grupo dentário foi o fator que mais influenciou a prevalência de PA nos DTE. (AU)

Quality of Life, Depression, Anxiety Symptoms and Mood State of Wheelchair Athletes and Non-athletes: A Preliminary Study.

The present study aims to compare quality of life, depression, anxiety symptoms, and profile of mood state of wheelchair athletes and non-athletes. Thirty-nine basketball and rugby wheelchair athletes (n = 23, nine women, age 36.0 ± 10.0 years; body mass 66.2 ± 13.8 kg; height 170.0 ± 8.5 cm) and non-athletes (n = 16, 4 women, 39.0 ± 14.2 years; body mass 79.6 ± 17.2 kg; height 170.0 ± 6.4 cm) were recruited. Quality of life, anxiety and depressive symptoms and mood disorders were evaluated by the Medical Outcomes Short-Form Health Survey (SF-36), State-Trait Anxiety Inventory, Beck Depression Inventory and Profile of Mood State questionnaire, respectively. Comparison between groups (non-athletes vs. athletes) was performed using Student's t-test for independent samples. No differences (p > 0.05) were found between non-athletes vs. athletes regards to quality of life, depressive and anxiety symptoms and profile of mood state. Overall, non-athletes and athletes presented medium anxiety symptoms and mild to moderate depressive symptoms. In conclusion, the wheelchair athletes and non-athletes presented similar quality of life, depressive and anxiety symptoms, and profile of mood state.

Protective effects of bark ethanolic extract from Spondias dulcis Forst F. against DNA damage induced by benzo[a]pyrene and cyclophosphamide.

This study evaluated the genotoxicity, mutagenicity, antigenotoxicity, and antimutagenicity effects on biochemical parameters of oxidative stress of the Spondias dulcis bark ethanolic extract on mice. The extract was evaluated in the doses of 500, 1000, and 1500 mg/kg bw via gavage. To evaluate the protective effects of the extract, benzo[a]pyrene (B[a]P) and cyclophosphamide (CP) were chosen as DNA damage inducers. Genotoxicity and antigenotoxicity were evaluated by the comet assay. Cytotoxicity, mutagenicity, and antimutagenicity were evaluated by the micronucleus test in bone marrow and peripheral blood. The biochemical parameters of oxidative stress were evaluated by the quantification of catalase activity (CAT) and reduced glutathione (GSH) in total blood, liver and kidney, and malondialdehyde (MDA), in liver and kidney. No genotoxic, cytotoxic, or mutagenic effect was found on mice exposed to the extract. The extract depleted the number of damaged nucleoids in total blood and the number of micronucleus (MN) in both cell types. The extract was able to increase CAT activity and GSH levels and decrease MDA levels after treatment with B[a]P and CP. The results indicate that the S. dulcis extract has potential to be used as preventive compound against DNA damage caused by CP and B[a]P.
