Tratamento de periodontite estágio III localizado grau C em um indivíduo fumante: um relato de caso / Treatment of periodontitis stage III localized grade C in smoker individual: a case report

Objetivo: A periodontite é uma doença infecto-inflamatória que acomete os tecidos de inserção periodontal, e ser fumante representa um risco modificável significativo para todos os graus da doença. Ainda, indivíduos fumantes apresentam uma resposta inflamatória alterada quando comparados a não fumantes. Nesse contexto, o objetivo deste estudo foi reportar um relato de caso de tratamento periodontal de paciente fumante pesado. Relato de caso: O paciente DRS, sexo masculino, 22 anos, foi encaminhado à Faculdade de Odontologia da Universidade Federal de Pelotas (UFPel) com a queixa principal de necessidade de "realização de uma limpeza dentária". Na anamnese, relatou fumar 20 cigarros ao dia, há 7 anos (7 maços-ano). Na consulta inicial, foi encontrado índice de placa visível (IPV) de 100% e índice de sangramento gengival (ISG) de 66,67%. Foi encontrado cálculo supragengival como fator retentivo de placa (FRP) em 46,30% dos sítios. Estabeleceu-se o diagnóstico de periodontite estágio III localizado grau C. Os exames periodontais foram realizados por um único pesquisador calibrado e optou-se pelo tratamento periodontal não cirúrgico. Ao exame de 12 meses, o paciente apresentou IPV de 23,45% e ISG de 22,83%. Houve ausência de FRP. De uma forma geral, foi possível constatar a diminuição significativa das bolsas periodontais, bem como o ganho significativo de inserção clínica periodontal. Considerações finais: Dessa forma, é possível concluir a efetividade da terapia periodontal não cirúrgica, aliada à manutenção periodontal e instruções de higiene para o tratamento de periodontite estágio III, grau C, em paciente fumante.(AU)

Objective: Periodontitis is an infect-inflammatory diseases that affects the periodontal attachment tissues, and being smoker represents a significant modifiable risk for all degrees of the disease. Moreover, smokers have an altered inflammatory response when compared to non-smokers. Therefore, the aim of this study was to report a case report of periodontal treatment of a heavy smoker. Case report: A patient DRS, male, 22 years old, was referred to the School of Dentistry of the Federal University of Pelotas (UFPel) with the main complaint of the need to "perform a dental cleaning". During the anamnesis, he reported smoking 20 cigarettes a day for 7 years (7 pack-years). In the initial appointment, a visible plaque index (VPI) of 100% and a gingival bleeding index (GBI) of 66.67% were found. Supragingival calculus was found as a plaque retentive factor (PRF) in 46.30% of the sites. The diagnosis of periodontitis stage III localized grade C was established. Periodontal examinations were performed by a single calibrated researcher and non-surgical periodontal treatment was chosen. At the 12-month appointment, the patient had an VPI of 23.45% and an GBI of 22.83%. There was absence of PRF. In general, it was possible to observe a significant decrease in periodontal pockets, as well as a significant gain in periodontal clinical attachment. Final considerations: Thus, it is possible to conclude the effectiveness of non-surgical periodontal therapy, combined with periodontal maintenance and hygiene instructions for the treatment of periodontitis stage III localized grade C in a smoker.(AU)

Evaluation of Some Haematological Metrics among Smokers in Port Harcourt, Rivers State, Nigeria

Introduction: Smoking is extremely toxic and has had a significant negative impact on society. One of the leading contributors to preventable illness and mortality has been found to be cigarette smoking. Aim: The goal of this study is to evaluate a few haematological metrics among smokers in Port Harcourt, Rivers State, and to verify the idea that smoking cigarettes either has a negative or favorable impact on these variables. Methodology: In this cross-sectional study, 100 participants between the ages of 20 and 45 were included, 50 of whom were smokers and 50 non-smokers. Venipuncture was used to obtain blood samples from the patients, which was then put into an EDTA vial for a full blood count (FBC) and other haematological analysis. The full blood count and erythrocyte sedimentation rate (ESR) were done using Haemo Auto Analyzer, Model XP-300 KOBE Japan by SYSMEX and the Westergreen method respectively. In order to analyze the data, Graph Prism Pad 6.2 and Microsoft Office Excel 2016 were both used. Using the student's independent t-test, a comparative study of mean and standard deviation values for the various parameters for test and reference ranges was conducted. Results: According to the findings, the average age of 50 smokers was 43.6200± 9.7250 years and that for the 50 non-smokers was 42.7800± 6.5440 years, which was statistically insignificant with p valve of 0.6130. Smokers’ haemoglobin level was 14.5080 ± 1.5590 (g/dL) and non-smokers was 12.1340 ± 0.70410 (g/dL). According to statistics, the level of Hb was significantly higher in smokers compared to non-smokers (P<0.0001). In comparison to non-smokers, the RBC count dramatically increased in smokers (P<0.0001) greater than in non-smokers at 5.2550 ± 0.6629 (x1012/L) and 4.6340 ± 0.5530 (x1012/L) respectively. While the total leucocyte count (TLC) in smokers is 8.0500 ± 1.8796 (x109/L), compared to 6.8580 ± 1.2454 (x109/L) in non-smokers. Statistics show that smokers have a higher total leucocyte count than non-smokers (P<0.0002). Smokers' platelet count is 255.7600±61.8351 (x109/L) while non-smokers' is 216.5800±35.5752 (x109/L).The study has statistically shown that smokers' platelet counts rose considerably in comparison to non-smokers (P<0.012). Conclusion: It may be concluded that uninterrupted smoking has an undue negative impact on haematological parameters such that increase occur in values of Hb, RBC, TLC and platelets. Significantly, these changes may increase the risk of serious health issues such as heart related defects, hardening of the arteries, Vaqu

Tabagismo no Brasil: percepções dos resultados de pesquisas domiciliares / Smoking in Brazil: insights from the results of the household surveys / Tabaquismo en Brasil: percepciones de los resultados de encuestas en hogares

Introdução: o uso do tabaco em suas diferentes formas continua a ser uma das principais causas de morte evitáveis no Brasil. Com uma história de sucesso notável, o Brasil alcançou uma das maiores reduções significativas na prevalência do tabagismo desde 1990. No entanto, é preocupante que a taxa de declínio do consumo de tabaco tenha diminuído nos últimos anos, conforme sugerem as pesquisas. Objetivos: o presente estudo teve como objetivo comparar os resultados de três pesquisas domiciliares realizadas pelo Instituto Brasileiro de Geografia e Estatística (IBGE). Métodos: foi realizada a comparação da prevalência do uso de tabaco entre entrevistados com 18 anos ou mais, assim como foi avaliada a porcentagem de mudanças na prevalência entre 2008, 2013 e 2019, usando dados de três pesquisas: The Global Tobacco Adult Survey, do ano de 2008, e a Pesquisa Nacional de Saúde do Brasil, dos anos de 2013 e 2019. Além disso, analisamos a prevalência no Brasil e seus estados de acordo com idade, gênero, nível educacional e raça. Resultados: a prevalência do tabagismo ativo diminuiu 19% entre 2008 e 2013, passando de 18,2% (IC 95%: 17,7;18,7%), em 2008, para 14,7% (IC 95%: 14,2;15,2%), em 2013. No entanto, em 2019, a prevalência foi de 12,6% (IC 95%: 12,2;13,0%), revelando uma redução de 14,3%. O tabagismo foi maior entre a população com baixo nível de escolaridade, status de renda mais baixo e raça/cor da pele preta e parda. Conclusão: a prevalência do tabagismo diminuiu no Brasil nas últimas três décadas. No entanto, recentemente, houve uma redução na intensidade da queda, exigindo atenção e análise cuidadosa das estratégias de prevenção e abandono do tabagismo.(AU)

Influence of smoking on autonomic functions in light and heavy smokers measured by heart rate variability

Background: Various studies using heart rate variability (HRV) as a tool have found reduced HRV in smokers in comparison with non-smokers. However, not many studies have studied the influence of smoking on HRV in light and heavy smokers calculated by pack years. Aim and Objective: The main aim of this study was to measure and compare the influence of smoking on autonomic functions in male light and heavy cigarette smokers using HRV. Materials and Methods: The present was conducted in the Department of Physiology, Navodaya Medical College, Raichur. Permission to conduct the study was obtained from the Institutional research ethical committee. This study was conducted among male cigarette smokers with age between 20 and 50 years who were apparently healthy. The selection of subjects participating in the study was done by simple random sampling, the subjects were residents of the Raichur district. The study group subjects were divided into light and heavy smokers considering both the amount and duration of smoking calculated by pack years. HRV was recorded by using the instrument Polygraph (AD instruments, Australia, model noML870). Statistical analysis was done by independent sample t-test to compare between the groups using EPI Info Version 7.0 software. A P < 0.05 was considered as statistically significant whereas a P < 0.001 was considered as highly significant. Results: The HRV parameters indicating sympathetic function such as low frequency (LF) component, LF power expressed in normalized unit (LFnu) and LF-HF ratio were significantly increased in heavy smokers in comparison to light smokers, whereas the HRV parameters indicating parasympathetic function such as total power, high frequency (HF) component and HF power expressed in normalized unit (HFnu) were significantly decreased in heavy smokers in comparison to light smokers. Conclusion: Increased sympathetic stimulation associated with a decrease in the cardiac vagal modulation leading to imbalance in the autonomic functions was more in heavy smokers when compared to light smokers.

Conducta tabáquica en estudiantes universitarios en Tunja (Boyacá)

Objetivo: Determinar el grado dependencia al tabaquismo y la motivación a la cesación del consumo de tabaco en estudiantes fumadores de una institución universitaria en la ciudad de Tunja (Boyacá). Materiales y métodos: Estudio transversal analítico con fase correlacional, con muestreo probabilístico por conglomerados. La identificación de la conducta tabáquica se realizó a través de los instrumentos de Fagerström y Richmond, en relación con la medición de los niveles de concentración de monóxido de carbono a través de cooximetría de pulso. Resultados: En los 79 estudiantes se observó una edad promedio de 21 años, siendo en la mayoría del sexo masculino (86%), con un consumo de cigarrillo en promedio de 4.2 años. Se pudo establecer que el 82.3% [IC : 73.4 - 91.1] de los estudiantes fumaron menos de 10 cigarrillos al día, con un grado leve correspondiente al 89 % [IC : 81.0-94.9], quienes se caracterizaron por fumar 5 o menos paquetes de cigarrillos al año. De igual manera el 82 % [IC : 73.4 - 89.9] de los fumadores se clasificaron como moderados y el 94 % [IC : 87.3 - 98.7] de ellos son poco dependientes a la nicotina. De igual forma, se estableció que solo el 32.91 % [IC : 24.1 - 43.0] presentó alto grado de motivación para dejar de fumar. En relación con el nivel de porcentaje de saturación de monóxido de carbono, en promedio fue de 6 % (DE 2.2), existiendo relación directamente proporcional con el grado y la clasificación del fumador determinada a través del método de Wilcoxon (P=0.00). Conclusión: Se identificó que la mayoría de los participantes presenta moderada motivación para la cesación del consumo; por lo tanto, es necesario incentivar el inicio de programas de deshabituación tabáquica que impacten la calidad de vida en adultos jóvenes, así mismo, en la reducción de la morbi/mortalidad por enfermedades respiratorias crónicas a futuro.

Objective: To determine the degree of dependence on smoking and the motivation to stop smoking in students of a university institution in the city of Tunja (Boyacá). Materials and methods: Analytical cross-sectional study with a correlational phase, with probabilistic cluster sampling. The identification of smoking behavior was carried out using the Fagerström and Richmond instruments, in relation to the measurement of carbon monoxide concentration levels through pulse co-oximetry. Results: An average age of 21 years was observed in the 79 students, with the majority being male (86%), with an average cigarette consumption of 4.2 years. It was established that 82.3% [95% CI: 73.4 - 91.1] of the students smoked less than 10 cigarettes a day, with a slight degree corresponding to 89% [95% CI: 81.0-94.9] who were characterized by smoking 5 or less cigarette packs per year. Similarly, 82% [95% CI: 73.4 - 89.9] of smokers were classified as moderate and 94% [95% CI: 87.3 - 98.7] of them were little dependent on nicotine. Similarly, it was established that only 32.91% [95% CI: 24.1 - 43.0] presented a high degree of motivation to quit smoking. In relation to the level of percentage of carbon monoxide saturation, on average it was 6% (SD 2.2), with a directly proportional relationship with the degree and classification of the smoker determined through the Wilcoxon method (P = 0.00). Conclusion: Most of the participants were found to present moderate motivation to stop smoking, therefore, it is necessary to encourage the start of smoking cessation programs that impact the quality of life in young adults, as well as reducing morbidity/mortality from chronic respiratory diseases in the future.

Association of the lipoprotein lipase and Apolipoprotein C-II gene polymorphisms with risk of dyslipidemia in smokers and non-smokers male

Objective: Dyslipidaemia is considered a metabolic abnormality andan important risk factor that leads to atherogenic cardiovascular diseases. Cigarette smoking is associated with dyslipidaemia. This study aimed to demonstrate whether lipoprotein lipase enzyme (LPL) and Apolipoprotein CII (APOCII) gene polymorphisms can be considered as independent genetic risk factors for dyslipidaemia among smokers with various smoking durations. Methods: A total of 185 males (90 smokers and 95 non-smokers)were included in this study, Lipid profiles were measured and DNA was isolated. The LPL-Hind III and APO CII-Ava II polymorphisms were determined using the polymerase reaction-restriction fragment length polymorphisms (RFLP) technique. Results: For the LPL-Hind IIIpolymorphism HþHþ genotype group, the triglycerides TG and very-lowdensity lipoprotein cholesterol VLDL-C concentrations were significantly higher and the high-density lipoprotein cholesterol HDL-C concentration was significantly lower than those of the HeH- genotype. ForAPO CII-Ava II polymorphisms, compared with those of the A2A2 genotype group, the total cholesterol TC, TG, low-density lipoprotein cholesterol LDL-C and VLDL-C concentrations were significantly increased in the A1A2 genotype group, while the HDL-C concentration was significantly decreased. Conclusions: The study revealed that the HþHþ or H þ H-genotype of the LPL-Hind III polymorphism and the A1A1or A1A2 genotype of the APOCII-Ava II polymorphism were at higher risk of developing dyslipidaemia compared to the HeH- genotype of the LPL-Hind III polymorphism and A2A2 genotype of the APOCII-Ava II polymorphism.

Influence of risk factors on the long-term survival of oral rehabilitation with extra-narrow implants: a retrospective study

Abstract Objective This study aimed to retrospectively collect clinical data to evaluate the influence of possible risk factors on the long-term success of implant treatment with extra-narrow (2.9 mm diameter) implants in a daily dental practice setting. Methodology Data were collected from records of patients who received at least one extra-narrow implant from 2012 to 2017, regarding implant survival, prosthesis survival, patient characteristics, and implant characteristics. The association between the dependent variables "implant survival", "prosthesis survival," and "adverse events" related to patient and implant characteristics was statistically evaluated by chi-square tests. Moreover, implant and prosthesis survival were analyzed by Kaplan-Meier survival curves. Results The sample was constituted of 58 patients (37 women and 21 men) with a mean age of 54.8 years old (SD: 12.5), followed up for up to eight years. In total, 86 extra-narrow implants were placed within this sample. Four implants were lost, resulting in an implant survival rate of 95.3%. A total of 55 prostheses were inserted and only one (1.8%) was lost, resulting in a prosthesis survival rate of 98.2%. The mean implant and prosthesis survival time was, respectively, 7.1 years and 6.3 years, according to the Kaplan-Meier survival analysis. A correlation was found between smoking and implant loss, which makes implant loss eight times more likely to occur in smokers than non-smokers. A significant association was also found between prosthesis loss and previous need of prosthesis repair. However, it was not considered clinically relevant. No association was found between the occurrence of adverse events and later implant or prosthesis loss. Conclusion High implant and prosthesis survival rates were found in the long term for treatment with extra-narrow implants. Moreover, a significant correlation between smoking and implant loss was observed.

Adaptación transcultural y validación de la escala de autoeficacia/tentaciones en Argentina / Transcultural adaptation and validation of the Self-efficacy/Temptations Scale in Argentina

Resumen La autoeficacia es la confianza en las propias habilidades para evitar fumar en situaciones que puedan desencadenar el deseo. Se la considera un importante predictor de recaídas. En Argentina no existe un instrumento válido que permita evaluarla. El objetivo del presente trabajo fue adaptar y validar una versión en español (Argentina) de la Escala de Autoeficacia/Tentaciones. Se llevó a cabo la adaptación transcul tural de la escala: traducción, revisión por un comité de expertos, traducción inversa, nueva revisión y prueba del cuestionario. Luego se evaluaron la confiabilidad (reproducibilidad, estabilidad y consistencia interna) y la validez. Se realizó un análisis factorial de componentes principales con rotación Varimax con datos de una muestra de 200 pacientes fumadores. Se obtuvo una versión cultural y lingüísticamente adaptada del instrumento, con una confiabilidad interobservador evaluada con el Coeficiente de Correlación Intraclase (ICC) = 0.90 y estabilidad de ICC = 0.77. En el análisis de la consistencia interna se obtuvo un α de Crombach global de 0.93 y de 0.85 para las versiones de 20 y 9 ítems, respectivamente. En el dominio de afectos positivos α = 0.82 y α = 0.89; afectos negativos α = 0.89 y α = 0.90 y para deseo intenso de fumar (craving) α = 0.84 y α = 0.75, también respectivamente para las dos versiones. En el análisis factorial exploratorio se identificaron tres factores que explicaron el 95% de la varianza del cuestionario en su versión extensa y 69% en su versión corta. Se obtuvo una versión argentina de la Escala de Autoeficacia/Tentaciones confiable y válida para ser aplicada a fumadores.

Abstract Self-efficacy is the confidence in one's own abilities to avoid smoking in situations that can trigger desire. It is considered an important predictor of relapses. In Argentina there is no valid instrument to evaluate it. The objective of this article was to adapt and validate a Spanish version (in local Argentinean language) of the Self-Efficacy/Temptation Scale. The transcultural adaptation of the scale was carried out: translation, review by a committee of experts, reverse translation, new review and test of the questionnaire. Reliability (reproduc ibility, stability and internal consistency) and validity were then evaluated. We performed a factor analysis of main components with Varimax rotation with data from a sample of 200 smokers. A culturally and linguistically adapted version of the instrument was obtained, with inter-observer reliability of Intraclass Correlation Coefficient (ICC) = 0.90 and stability of ICC = 0.77. The internal consistency analysis yielded a global Crombach α = 0.93 and 0.85 for versions of 20 and 9 items, respectively. In the domain of Positive Affections α = 0.82 and α = 0.89; Negative Affections α = 0.89 and α = 0.90 and for Craving α = 0.84 and α = 0.75, also respectively for the two versions. In the exploratory factor analysis, three factors were identified that explained 95% of the variance of the questionnaire in its extensive version and 69% in its short version. A reliable and valid Argentinean version of the Self-Efficacy/Temptation Scale was obtained, to be applied to smokers.

Effect Of Cigarette Smoking On Sperm Morphology Of Infertile Men

Background:Cigarette smoking is a serious health problem of most societies. Smoking has been suggested to contribute to a number of diseases including male infertility. The present study was aimed at studying effect of cigarette smoking on Sperm morphology of infertile men.Material And Methods:A total of one hundred infertile men (50 Non-smokersand 50 Smokers) between the age group 20-45 years were taken into study. The Sperm morphology in the infertile Non-smokersand infertile Smokers group were compared using Z Test. Infertile Smokers which were divided into Group A (?1 and ?10 cigarettes/ day), Group B (>10 and <20 cigarettes/ day) and Group C (?20 cigarettes/ day) were analyzed for Sperm morphology by ANOVA Test. Result:We observed that Sperm morphology was significantly lower (p<0.01) in infertile Smokers group than infertile Non-smokersgroup. We also observed that Sperm morphology was significantly decreased (p<0.01) in accordance with the severity of smoking.Conclusion:Cigarette smoking adversely affect sperm morphology.

Factores asociados al recubrimiento total de recesiones gingivales clases I y II de Miller / Factors associated to complete coverage of Miller class I and II gingival recessions

Introducción: La recesión gingival es uno de los defectos estético-funcionales más comunes en la cavidad oral. Se caracteriza por la exposición de la superficie de la raíz debido a un desplazamiento del margen gingival apical a la unión amelocementaria. La literatura reporta un porcentaje de recubrimiento de la raíz favorable en recesiones gingivales clases I y II de Miller; sin embargo, varios estudios no lograron el recubrimiento total, lo que ha sido asociado a varios factores. Objetivo: Identificar los factores asociados al recubrimiento total de recesiones gingivales clases I y II de Miller en dientes tratados con colgajo de reposición coronal. Métodos: Se consultaron las bases de datos PubMed SciELO, Redalyc, Lilacs y Scopus. De 105 investigaciones, se analizaron 7 que cumplieron los criterios de inclusión. Análisis e integración de las informaciones: El metaanálisis dio resultados no concluyentes, debido a la alta heterogeneidad de los estudios. Sin embargo, se detectaron los siguientes factores: el uso de ácido etilendiaminotetraacético (p < 0,0001), la presencia de tejido queratinizado adjunto ≥ 2 mm (p = 0,019), una profundidad de recesión gingival inicial > 3 mm (p = 0,020) y pacientes que fumaban más de 10 cigarrillos diarios (p < 0,05). Conclusiones: Se identificaron el uso de ácido etilendiaminotetracético, la presencia de tejido queratinizado, la profundidad de la recesión y pacientes fumadores como posibles factores que intervienen el recubrimiento total de recesiones gingivales clases I y II de Miller en dientes tratados con colgajo de reposición coronal(AU)

Introduction: Gingival recession is one of the most common esthetic-functional defects of the oral cavity. It is characterized by exposure of the root surface due to displacement of the apical gingival margin to the cementoenamel junction. The literature about the topic reports a percentage of favorable root coverage of Miller class I and II gingival recessions. However, several studies do not report complete coverage, which has been associated to a number of factors. Objective: Identify the factors associated to complete coverage of Miller class I and II gingival recessions in teeth treated with coronally repositioned flap. Methods: A search was conducted in the databases PubMed, SciELO, Redalyc, Lilacs and Scopus. Of a total 105 studies retrieved, seven met the inclusion criteria. Data analysis and integration: The meta-analysis did not achieve conclusive results, due to the high heterogeneity of the studies. However, the following factors were identified: use of ethylenediaminetetraacetic acid (p < 0.0001), presence of adjacent keratinized tissue ≥ 2 mm (p = 0.019), initial gingival recession depth > 3 mm (p = 0.020) and patients who smoked more than 10 cigarettes a day (p < 0.05). Conclusions: Use of ethylenediaminetetraacetic acid, presence of keratinized tissue, recession depth and smoker patients were identified as possible factors involved in the complete coverage Miller class I and II gingival recessions in teeth treated with coronally repositioned flap(AU)

Nasal Mucociliary Clearance in Smokers: A Systematic Review

Abstract Introduction Smoking is one of the most important causes of mortality and morbidity in the world, as it is related to the risk factor and etiology of respiratory-tract diseases. Long-term smoking causes both structural and functional damage in the respiratory airways, leading to changes in nasal mucociliary clearance (NMC). Objectives The aim of the present study was to look systematically into the current literature and carefully collect and analyze results to explore NMC in smokers. Data Synthesis Two independent reviewers conducted a literature search on some Electronic database: Pubmed, Medline, Ebsco, Springer Link, Science Direct, Scopus, and Proquest searching for articles fulfilling the inclusion and exclusion criteria. The lead author independently assessed the risk of bias of each of the included studies and discussed their assessments with the other two authors to achieve consensus. Of the 1,654 articles identified in the database search, 16 met the criteria for this review. Most of the articles (15 out of 16) showed the impairment of NMC in smokers. Conclusion The present systematic review suggests that there is an impairment of NMC in smokers. The impairment is not only observed in cigarette smoking, but also in passive smoking, bidi smoking, electronic smoking, and hookah smoking. The impairment of NMC in chronic exposure to smoking is caused by the ciliotoxic effect, hypersecretion and viscoelastic change of mucous, airway surface liquid depletion, increased oxidative stress, and deteriorations in the inflammatory and immune systems.

Comparison of total antioxidant capacity of saliva in men based on daily cigarette consumption / Comparação da capacidade antioxidante total da saliva em homens com base no consumo diário de cigarros

Objectives: Antioxidants play an important role in neutralizing of destructive effects of free oxygen and nitrogen radicals. There are contradictory results regarding the relationship between cigarette smoking and total antioxidant capacity of saliva. In this study, the total antioxidant capacity of saliva has been compared in normal smokers, heavy smokers and non-smokers. Material and methods: In this cross-sectional study, 28 heavy male smokers (more than one pack of cigarettes per day), 28 normal male smokers (less than one pack of cigarettes per day), and 28 male non-smokers aged 25 to 40 years old entered the study. Unstimulated saliva was collected by Spitting method. The total antioxidant capacity of saliva was measured using Ferric Reducing Antioxidant Power Assay. Descriptive statistics, ANOVA, and Tukey tests were used to analyze the data. Results: The mean total antioxidant capacity of saliva in male non-smokers was 0.0598 ± 0.08 µmol / L, in normal male smokers was 0.049 ± 0.04 µmol / L, and in heavy male smokers was 0.0388 ± 0.035 µmol / L, which did not show any significant difference between the groups (P > 0.05). Conclusion: The results of this study indicate that smoking does not have a significant effect on total antioxidant capacity of saliva in smokers (AU)

Objetivos: Os antioxidantes desempenham um papel importante na neutralização dos efeitos destrutivos do oxigênio livre e dos radicais de nitrogênio. Existem resultados contraditórios entre a relação do tabagismo e a capacidade antioxidante total da saliva. Neste estudo, a capacidade antioxidante total da saliva foi comparada em fumantes normais, fumantes pesados e não fumantes. Material e métodos: Neste estudo transversal, 28 fumantes pesados (mais de um maço de cigarros por dia), 28 fumantes normais (menos de um maço de cigarros por dia) e 28 homens não fumantes com idade entre 25 e 40 anos de idade foram incluídos no estudo. A saliva não estimulada foi coletada pelo método Spitting. A capacidade antioxidante total da saliva foi medida usando o ensaio de poder antioxidante redutor férrico. Estatística descritiva, ANOVA e testes de Tukey foram usados para analise dos dados.Resultados: A capacidade antioxidante total média da saliva em não fumantes do sexo masculino foi de 0,0598 ± 0,08 µmol / L, em fumantes normais do sexo masculino foi de 0,049 ± 0,04 µmol / L, e em fumantes pesados do sexo masculino foi de 0,0388 ± 0,035 µmol / L, e não foi observada diferença significativa entre os grupos (P> 0,05). Conclusão: Os resultados deste estudo indicaram que o tabagismo não tem efeito significativo na capacidade antioxidante total da saliva em fumantes (AU)

Condições periodontais e fatores associados a profundidade de sondagem em pacientes de uma faculdade do sul do Brasil / Periodontal conditions and factors associated with the probing depth in patients from a faculty in southern Brazil

RESUMO Objetivos: Verificar os sinais clínicos periodontais e investigar a os níveis de profundidade de sondagem (PS) e fatores associados em pacientes atendidos nas Clínicas da Faculdade IMED, localizada em um município do sul do Brasil. Metodologia: Os dados foram coletados em 193 prontuários de pacientes que buscaram atendimento odontológico, no período de 2017-2018, agrupados em sociodemográficos, hábitos de higiene bucal, hábitos nocivos e doenças crônicas. Os dados clínicos foram índice de placa dental visível (IPV), índice de sangramento gengival (ISG) e PS. Após realizadas análises descritivas foi construído um modelo de Regressão linear simples e múltiplo para verificar relações entre as variáveis ao p-valor<0,05. Resultados: A maioria dos pacientes são do sexo feminino (63,2%) com média de 40,8 anos (±14,58). Os resultados descritivos de IPV, ISG e PS foram 39,11±32,28%, 21,81 ±22,43% e 2,91 ±1,09mm, respectivamente. Após os ajustes no modelo de regressão múltiplo, os portadores de diabetes e a a quantidade de cigarros fumados por dia influenciaram no nível de PS. Conclusões: Os achados desta investigação mostram um alto IPV e de SG. Apesar da média da PS ter sido baixa, portadores de diabetes e fumo foram fatores preditivos de maiores níveis de PS.

ABSTRACT: Objectives: To evaluate periodontal clinical signs and investigate the probing depth levels (PD) and associated factors in patients attending the Dental Clinics of the Faculty IMED, located in a municipality in southern Brazil. Material and Methods: The data were collected of 193 records of patients who demand dental care in the Dental Clinics for periodontal treatment, in the period 2017- 2018: sociodemographic data, oral hygiene habits, tobacco use and chronic diseases. The clinical data were: gingival bleeding index (GBI), visible plaque index (VPI) and PD. The statistical analyzed the relationship between probing depth and exposure variables, using a linear regression linear model (p-value<0.05). Results: The majority of the patients attended were female (63.2%) and 40.8 years old on average (± 14.58). The descriptive results of VPI, GBI e PD were: 39.11 ± 32.28%, 21.81 ± 22.43%, and 2.91 ± 1.09mm, respectively. After adjustments in the multiple regression model, it was observed that diabetes and quantity of cigarettes smoked had an influence on PD. Conclusions: The results obtained in this research allowed to verify a high index of VPI and GBI in the patients. The mean PD of the individuals was low, however, it was possible to verify that having diabetes and smoking a large amount of cigarettes daily were predictive factors of higher levels of PD.

Efectividad de una intervención cognitivo-conductual para dejar de fumar combinada con vareniclina / Effectiveness of a Cognitive-Behavioral Intervention to Smoking Cessation Combined with Varenicline

Resumen Diferentes investigaciones han evidenciado que el tratamiento con vareniclina es efectivo para dejar de fumar cuando se combina con un tratamiento psicológico. Sin embargo, existe una carencia de estudios respecto a cuánta efectividad aporta la vareniclina al tratamiento psicológico. El objetivo del presente estudio piloto fue evaluar si la efectividad de una intervención psicológica cognitivo-conductual incrementa con la inclusión de la vareniclina. La muestra de este estudio la conformaron 22 fumadores (M edad = 30.5; de = 15.4 años), con un consumo diario promedio de 12.29 (de = 5.7) cigarrillos. Cada participante eligió una de dos intervenciones: 11 fumadores recibieron la Intervención Breve Motivacional para Dejar de Fumar (ibmdf) y 11 la misma intervención más vareniclina. Los resultados indican que no hay diferencias significativas entre las intervenciones. Así, la inclusión de la vareniclina no incrementó la efectividad de la intervención psicológica. Las conclusiones de este estudio deben ser tomadas con cautela debido al tamaño de la muestra, por lo tanto, es necesario aumentar las investigaciones al respecto.

Abstract Different studies have shown that treatment with varenicline is effective for smoking cessation when it is combined with psychological treatment. However, there are few studies on the effectiveness that varenicline adds to psychological treatment. The aim of this pilot study was to assess if the effectiveness of a cognitive behavioral intervention increases with the inclusion of varenicline. The sample of this study were 22 smokers (M age = 39.5, SD = 15.4 years), with an average daily consumption of 12.29 cigarettes (SD = 5.7). Each participant chose one of the two interventions: 11 smokers received the Motivational Smoking Cessation Brief Intervention (mscbm) and 11 the same intervention plus varenicline. The results showed no significant differences between interventions. Thus, the inclusion of varenicline did not increase the effectiveness of psychological intervention. The findings of this study should be taken with caution due to the sample size. More research is therefore needed.

How are COPD. AR smokers? Smoking Characteristics of Populations With and Without COPD / ¿Cómo son los fumadores del EPOC. AR? Características de tabaquismo en población con y sin EPOC

Introduction: The COPD.AR Study was conducted between 2014 and 2016 in Argentina to determine the prevalence of COPD in the country. This work was carried out to compare the smoking characteristics of smokers with and without COPD of said study, to know how many of them received medical advice, the characteristics of their previous attempts to quit and their exposure to secondhand tobacco smoke. Materials and Methods: The association between smoking characteristics and COPD was evaluated by Odds Ratio, its 95% confidence interval and p value corresponding to the hypothesis test, using the chi square technique. Results: We included 3469 surveys of subjects older than 39 years, 42.2% men. 70.7% were current or former smokers and 53.3% had spirometric characteristics of COPD. 34.7% are current smokers, 73.4% out of which think about quitting; 64% received advice about it and only 7.3% reported having used some treatment. 40.2% of the respondents reported exposure to environmental smoke, and 56.1% reported occupational exposure to tobacco smoke. The majority of COPD.AR smokers smoke less than 20 cigarettes per day; there is a higher prevalence of COPD in men and a higher percentage of never smokers with COPD in women. A high percentage thinks of quitting smoking, a little lower among patients with COPD, who had more previous attempts to quit. Almost half of the subjects did not receive any medical advice and a very low percentage used drugs to quit. There is high exposure to secondhand smoke in homes and workplaces. Conclusions: COPD.AR smokers smoke less than 20 cigarettes a day; there are more men, a high percentage want to quit and very few receive medical advice or drugs.

Regresión de la luminosidad del color posblanqueamiento dental casero en pacientes fumadores y no fumadores / Color luminosity regression after home tooth whitening in smoking and nonsmoking patients

Introducción: Existen muchos estudios de efectividad del blanqueamiento dental; sin embargo, son muy pocos los que hablan de regresión de color (fenómeno que se produce posterior a un blanqueamiento dental), lo mismo ocurre en relación a pacientes fumadores. Objetivo Determinar la regresión de la luminosidad del color en pacientes sometidos a blanqueamiento dental casero con peróxido de carbamida al 10 por ciento, en pacientes fumadores y no fumadores. Métodos: Estudio descriptivo, transversal, en 43 pacientes de un grupo de 60 previamente tratados de forma casera durante 3 semanas con peróxido de carbamida al 10 por ciento. Fueron divididos en un grupo experimental (pacientes fumadores GE) y grupo control (no fumadores GC). Se midió la variación del color con el espectrofotómetro Vita Easyshade® a la semana, mes, 6 meses y 9 meses posblanqueamiento. Los datos obtenidos mediante la medición con el espectrofotómetro fueron analizados por el test de Shapiro Wilk y Kolmogorov-Smirnov para evaluar normalidad de la distribución y, posteriormente, sometidos al test Mann-Whitney U y Wilcoxon W (#945; = 0,05). Resultados: El delta L* fue: 2,3 (GE) y 3,66 (GC); deltas calculados con datos de los 9 meses vs. semana posblanqueamiento. No hubo diferencias estadísticamente significativas entre ambos grupos. Conclusiones: No existen diferencias estadísticamente significativas en la regresión del color posteriores al blanqueamiento casero con peróxido de carbamida al 10 por ciento en pacientes fumadores y no fumadores(AU)

Introduction: Many studies have been conducted about the effectiveness of tooth whitening, but few refer to color regression (a phenomenon occurring after tooth whitening) or to smoking patients. Objective: Determine color luminosity regression in smoking and nonsmoking patients undergoing home tooth whitening with 10 percent carbamide peroxide. Methods: A descriptive cross-sectional study was conducted of 43 patients from a group of 60 previously undergoing home treatment with 10 percent carbamide peroxide for 3 weeks. The patients were divided into an experimental group (EG, smoking patients) and a control group (CG, nonsmoking patients). A Vita Easyshade® spectrophotometer was used to measure color variation one week, one month, 6 months and 9 months after whitening. The data obtained by spectrophotometry were analyzed with the Shapiro-Wilk and the Kolmogorov-Smirnov tests to evaluate the normality of the distribution, and then they were subjected to the Mann-Whitney-Wilcoxon U test (α = 0,05). Results: Delta L* was 2,3 (EG) and 3,66 (CG); delta values were estimated from data obtained 9 months vs. one week after whitening. No statistically significant differences were found between the groups. Conclusions: No statistically significant color regression differences are found in either smoking or nonsmoking patients after home whitening with 10 percent carbamide peroxide(AU)
