Maternal Knowledge of Oral Health During Pregnancy and Childbirth.

OBJECTIVE: This cohort study was to investigate maternal knowledge of the oral health of woman and children during pregnancy and after childbirth, and the associated factors. METHODS: Groups of women participating in a public prenatal dental care programme in Brazil were assessed, in two different stages. In the first stage, pregnant women were assessed for their own oral health. In the second stage, after childbirth, women were assessed for the oral health of their child. The examiner assigned a maternal knowledge score to the questionnaires, considering the ideal alternatives within the context of oral health promotion as correct answers. Statistical analysis included the Kruskal-Wallis and multiple linear regression tests, considering a level of significance of P < 0.05. RESULTS: Ninety-eight women were included in the study, with a mean age 26.27 years (SD 6.51). In the regression analysis, the maternal knowledge score was associated with the presence of myths about oral health (P < 0.01), the children first dental appointment in the first year of life (P = 0.07), the presence of a non-nutritious sucking habit (P < 0.01), considering dental treatment to be important during pregnancy (P < 0.01), and having been instructed on oral health during pregnancy (P < 0.01) and after the children birth (P = 0.02). CONCLUSION: This study suggests that the women showed a regular score of knowledge about their oral health and that of their children, as they still believed in some myths about oral health and the risks of dental treatment during pregnancy. Women who received guidance on oral health in pregnancy and after birth showed higher knowledge of their oral health and that of their children, demonstrating the importance of carrying out health promotion actions during pregnancy and the first years of the child's life.

Geographic Information Systems (GIS) to Assess Dental Caries, Overweight and Obesity in Schoolchildren in the City of Alfenas, Brazil.

Childhood-related obesity and overweight are increasing concerns for the health and well-being of children. Dental caries (decay) is the most prevalent oral disease during childhood, and several studies have suggested that nutritional status and dental caries are associated in children. Therefore, this study aimed to determine the geographic distribution of childhood overweight/obesity and dental caries in a medium-sized Brazilian city. This cross-sectional study was conducted with 269 children of both genders enrolled in four public schools in the city of Alfenas. The children were clinically examined to assess cavitated dental caries and nutritional status (overweight and obesity). In addition, the GIS was used for the geospatial clustering analyses. A heat map was created by the Kemel method to estimate the concentration of the outcomes. The cavitated dental caries and overweight/obesity were also pointed out by dots on the map. However, of the 269 children, 118 were boys (43.87%) and 151 were girls (56.13%). One hundred fifty-seven children (58.4%) were classified as having "non-cavitated caries," while 112 (41.6%) were classified as having "cavitied caries." In the nutritional status assessment, 204 children (75.84%) were classified as "eutrophic," while 65 children (24.16%) were classified as "overweight/obesity," A geographical correlation of dental caries with overweight/obesity may exist in the northeast and southwest areas. In conclusion, a geographical concordance between the dental caries and the occurrence of overweight/obesity among the schoolchildren from Alfenas may exist in some areas. Future studies are necessary.

Impact of the COVID-19 pandemic on head and neck cancer patients: systematic review and meta-analysis.

OBJECTIVES: This manuscript presents a systematic review of the impact of the COVID-19 pandemic on head and neck cancer (HNC) patients. A meta-analysis was made to compare the number of treated/operated HNC patients in the pre-COVID-19 era versus the COVID-19 era. This investigation was based on previous reports showing a delay in the diagnosis and treatment of new cases of cancer during the pandemic. Worsening in cancer prognosis would be expected as a result of the delayed treatments. METHOD AND MATERIALS: An electronic search was conducted using the PubMed/MEDLINE, Embase, Web of Science, Scopus, and The Cochrane Library databases. Relevant articles were selected based on specific inclusion criteria. RESULTS: A total of 8,942 HNC patients were included. A higher prevalence in male (1,873) in comparison to female (1,695) was observed considering 3,568 patients. Regarding staging, the majority of cases were stage III to IV. The treatment type more frequently described was surgery. Positive diagnosis for COVID-19 in the pre-oncologic treatment was reported for 242 patients, and for post-oncologic treatment in 119 patients. Mortality by COVID-19 was reported for 27 HNC patients. The meta-analysis revealed a significantly smaller number of surgeries/oncologic treatments of HNC patients performed (2,666) in the COVID-19 era when compared to the pre-COVID-19 era (3,163) (Mantel-Haenszel odds ratio = 0.81, 95% CI = 0.65 to 1.00, P = .05). CONCLUSION: The impact of the COVID-19 pandemic on HNC patients occurred mainly in the number of surgeries/oncologic treatments, showing a significantly smaller number of surgeries/oncologic treatments performed in the COVID-19 era rather than the pre-COVID-19 era.

Oral Health and related inequalities among visual impairment people in a Brazil municipality / Saúde bucal e desigualdades relacionadas entre pessoas com deficiência visual em um município brasileiro

ABSTRACT Objective: To evaluate the oral health and related factors among people with visual impairment in a municipality in southeastern Brazil. Methods: A cross-sectional and descriptive household study was carried out on a representative sample of people with visual impairments in a medium-sized city in Brazil. A clinical-dental examination was performed (evaluating tooth loss, caries, periodontal health, dental plaque use and need of prosthesis) and a semistructured questionnaire was applied, investigating the socioeconomic conditions (sex, age, marital status, skin color and income) and the use of dental services (reason, time since, and type of service used [private/public] in last dental visit). Descriptive and bivariate analysis were performed to asses the factors related to oral health. Results: The mean age of participants was 65 years (±15.05), with the majority women (70.9%). 53.1% of the interviewees were edentulous, but 58.2% had a good perception of oral health. The blind ones use less public services (p=0.038) and with a lower frequency (p=0.014) than subjects with low vision. Those with less schooling had higher tooth loss and lower periodontal problems (p <0.05). There was a reduction of dental plaque six months after the educational action (30.7%; p=0.01), especially among the low vision participants (p=0.01). Conclusion: Severe tooth loss and unsatisfactory hygiene contrast with self-perception of oral health. Visual acuity and schooling were related to access and oral health. Actions for promotion and equity are necessary to overcome the inequalities encountered.

RESUMO Objetivo: Avaliar a saúde bucal e fatores relacionados entre deficientes visuais em município do sudeste brasileiro. Métodos: Foi realizado um estudo domiciliar, transversal e descritivo em uma amostra representativa de pessoas com deficiência visual em uma cidade de médio porte do Brasil. Realizou-se o exame clínico bucal (avaliando perda dentária, cárie, saúde periodontal, placa dentária, uso e necessidade de prótese) e aplicou-se um questionário semiestruturado, investigando as condições socioeconômicas (sexo, idade, estado civil, cor da pele e renda) e o uso de serviços odontológicos (motivo, tempo decorrido e tipo de serviço utilizado [privado/público] na última consulta odontológica). Foram realizadas análises descritivas e bivariadas para avaliar os fatores associados à saúde bucal. Resultados: A idade média dos participantes foi de 65 anos (±15,05), com maioria de mulheres (70,9%). 53,1% dos entrevistados eram edêntulos, porém, 58,2% apresentaram percepção de saúde bucal boa. Os cegos usam menos os serviços públicos (p=0,038) e em menor frequência (p=0,014) que os sujeitos com baixa visão. Os menos escolarizados apresentam maiores perdas dentárias e menores problemas periodontais (p<0,05). Houve redução de placa dentária seis meses após ação educativa (30,7%; p=0,01), sobretudo entre os sujeitos com baixa visão (p=0,01). Conclusão: Elevada perda dentária e higienização insatisfatória contrastaram com autopercepção dos agravos bucais. Acuidade visual e escolaridade relacionaram-se ao acesso e saúde bucal. Ações de promoção e equidade são necessários para superar desigualdades encontradas.

Fatores associados à autoavaliação de saúde bucal por adultos em hemodiálise / Factors associated with self-rated oral health in adults with hemodialysis

Resumo Introdução Pacientes com insuficiência renal crônica podem apresentar prejuízos em sua saúde bucal em decorrência da própria doença, do tratamento e das alterações de estilo de vida associadas. Objetivo Avaliar os fatores associados à autoavaliação de saúde bucal ruim entre adultos com insuficiência renal crônica submetidos à hemodiálise. Método Estudo transversal com 243 adultos submetidos à hemodiálise em um hospital do sul de Minas Gerais nos anos de 2013 e 2014. O desfecho foi avaliado pelo autorrelato da condição bucal dicotomizada em boa (ótima/boa) e ruim (regular/ruim/péssima). As variáveis independentes incluíram condições sociodemográficas, saúde geral, saúde bucal e uso de serviços odontológicos, a partir de informações coletadas por meio de questionário. A associação entre o desfecho e as variáveis independentes foi testada por meio de modelos logísticos múltiplos com inclusão hierarquizada de variáveis. Resultados A prevalência de autoavaliação de saúde bucal ruim foi de 35,4%. Os mais jovens (p = 0,015), os que se submetem à hemodiálise há menos tempo (p = 0,016), têm halitose (p <0,001), necessitam de tratamento odontológico (p <0,001) e tiveram a última consulta odontológica por motivo diferente de dor (p = 0,027) expressaram maiores chances de autoavaliação de saúde bucal ruim, independentemente de condições sociodemográficas e de saúde. Conclusão Condições sociodemográficas, tempo em hemodiálise, agravos à saúde bucal e uso de serviços odontológicos influenciaram a autoavaliação da saúde bucal dos adultos submetidos à hemodiálise.

Abstract Background Patients with chronic renal failure may have their oral health impaired as a result of the disease itself, its treatment, and its associated lifestyle alterations. Objective To assess the factors associated with poor self-rated oral health among adults with chronic renal failure treated by hemodialysis. Method This is a cross-sectional study with 243 adults undergoing hemodialysis in a hospital in Minas Gerais, Brazil in 2013-2014. The outcome was assessed by the self-report of oral health categorized into good (excellent/good) and bad (fair/bad / very bad). The independent variables included sociodemographic conditions, general health, oral health, and the use of dental services were collected through a structured questionnaire. The association between the outcome and the independent variables was tested using multiple logistic models with hierarchical inclusion of variables. Results The prevalence of poor self-rated oral health was 35.4%. The youngest (p = 0.015), those who have undergone hemodialysis in the shortest time (p = 0.016), have halitosis (p <0.001), need dental treatment (p <0.001), and had their last dental appointment not for pain (p = 0.027) expressed higher odds of poor self-rated oral health, independently of sociodemographic and health conditions. Conclusion Sociodemographic conditions, time on hemodialysis, oral impairments, and use of dental services affected the oral health self-assessment among adults undergoing hemodialysis.

Impact of oral comorbidities on incarcerated women: an integrative review.

INTRODUCTION: Oral health care directly impacts the well-being of incarcerated women. It is related to the quality of life, social and economic discrepancies and lack of access to programs that offer free dental services and health promotion for this population. OBJECTIVES: This work aimed to understand oral health challenges faced by women incarcerated in Brazil and worldwide. MATERIAL AND METHOD: The following databases were selected: EMBASE, (Virtual Health Library=LILACS+BDENF), Scielo, Scopus, Cochrane-Library and the PubMed search engine. These databases were searched until the closing date of October 2021 with no time limit for the searches. The key words used in the searches were "incarceration", "prison", "woman", and "oral health". RESULTS: Caries, periodontal disease, tooth pain, and the use of dental prostheses were the most prevalent oral health conditions amongst incarcerated women in Brazil and worldwide. Regarding the level of scientific evidence, the included articles fit level III, according to Melnyk and Fineout. DISCUSSION: Bearing in mind the limitations of the study, oral diseases in the global context showed that the quality of life related to oral and systemic health of women during and after incarceration was negatively affected. It is also essential for further clinical and follow-up studies to be carried out on incarcerated women that address their actual oral health needs.

Systemic and local effects of doxycycline and low-intensity laser treatment on periodontitis in rats.

PURPOSE: This study evaluated the systemic and local effects of doxycycline (DOX) and low-intensity laser (LIL) treatment as adjuvants to scaling and root planing (SRP) in the treatment of experimental periodontitis in rats. METHODS: The sample consisted of 180 male rats (Rattus norvegicus albinus, Wistar), of which 30 did not receive induction of periodontal disease (negative control [NC] group) and 150 received induction of periodontal disease in the lower first molar. After 7 days, the ligature was removed, and the animals were divided into the following groups: NT (no treatment), SRP (SRP), DOX (SRP and DOX irrigation), LIL (SRP and laser irradiation), and DOX+LIL (SRP, DOX, and LIL). The animals were euthanized at 7, 15, and 30 days; thereafter, biochemical, radiographic, histological, and immunohistochemical analyses were performed. RESULTS: In the intragroup analysis, lower concentrations of α-1-glycoprotein acid (α-1-Ga) and complement 3 (C3) were observed in the DOX+LIL group than in all other groups at all time points, as well as lower levels of complement 4 (C4) at 15 and 30 days (P<0.001). Less bone loss was observed in the DOX, LIL, and DOX+LIL groups than in the NC and SRP groups at all time points (P<0.001). There was a smaller number of tartrate-resistant acid phosphatase (TRAP)-positive cells in the DOX+LIL group than in the other groups at all time points (P<0.001). Positive correlations were observed between the systemic levels of α-1-Ga, C3, and C4 and the number of TRAP-positive cells. CONCLUSIONS: The combination of DOX with LIL as SRP adjuvants was effective both systemically and locally for the treatment of experimental periodontitis in rats.

Utilização de serviços odontológicos por pacientes em tratamento oncológico / Use of dental services by patients in oncological treatment

Introdução: a busca por atendimento odontológico é um parâmetro importante para averiguar como os indivíduos compreendem a saúde bucal. Objetivo: avaliar a utilização de serviços odontológicos e fatores associados em pacientes oncológicos em Minas Gerais, Brasil. Material e método: estudo transversal, realizado com uma amostra de 441 pacientes adultos frequentadores de uma associação voluntária de apoio a pacientes oncológicos no Estado de Minas Gerais, Brasil. O desfecho foi avaliado por meio do autorrelato de consulta odontológica no último ano. As variáveis independentes incluíram condições socioeconômicas, saúde geral e relacionada ao câncer, saúde bucal e cuidados odontológicos. As associações entre o desfecho e as variáveis independentes foram testadas por meio de regressão logística bivariada e múltipla, sendo os resultados expressos por meio de odds ratio (OR) e intervalos de confiança de 95% (IC95%). Resultado: a prevalência de consulta odontológica no último ano foi de 33,3%. Os indivíduos que possuem entre quatro e sete (OR: 1,80; IC95%: 1,02-3,18) e aqueles com oito ou mais anos de estudo (OR: 3,20; IC95%: 1,07-9,60) apresentaram maiores, enquanto os edêntulos (OR: 0,44; IC95%: 0,21-0,92) apresentaram menores chances de consulta odontológica no último ano, independentemente de condições socioeconômicas, saúde geral e saúde bucal. Conclusão: foi baixa a procura por consulta odontológica no último ano entre os pacientes oncológicos. Além disso, houve desigualdades relacionadas à escolaridade e ao número de dentes remanescentes na utilização dos serviços. A identificação e priorização dos grupos com acesso desfavorável aos serviços são fundamentais no planejamento da prestação de cuidados odontológicos a essa população.

Introduction: the search for dental care is an important parameter to determine how individuals understand the oral health. Objective: to evaluate the use of dental services and associated factors in cancer patients in Minas Gerais, Brazil. Material and method: a cross-sectional study carried out with a sample of 441 adult patients attending a voluntary association to support cancer patients in the State of Minas Gerais, Brazil. The outcome was assessed through self-report of dental appointments in the last year. Independent variables included socioeconomic status, general and cancer-related health, oral health, and dental care. The associations between the outcome and the independent variables were tested using bivariate and multiple logistic regression, and the results were expressed as odds ratios (OR) and 95% confidence intervals (95%CI). Result: the prevalence of dental appointments in the last year was 33.3%. Individuals who have between four and seven (OR: 1.80; 95%CI: 1.02-3.18) and those who have eight or more years of schooling (OR: 3.20; 95%CI: 1.07-9 .60) had greater, whereas, the edentulous (OR: 0.44; 95%CI: 0.21-0.92) had less odds to have had a dental appointment in the last year, independently of socioeconomic status, general health and oral health conditions. Conclusion: recent dental care was uncommon among cancer patients. Furthermore, there were inequalities related to schooling and the number of remaining teeth in the use of services. The identification and prioritization of groups with unfavorable access to services are fundamental in planning the provision of dental care to this population.

Influence of Doxycycline and InGaAlP Diode Laser at 660 nm Wavelength in the Treatment of Periodontitis Induced in Rats: In Vivo Study.

This study evaluated the influence of Doxycycline (DOX) and Low-Intensity Laser (LIL) (InGaAlP diode laser) as scaling and root planing (SRP) adjuvants in the treatment of periodontitis induced in rats. The rats received periodontal disease induction, and after 7 days, the ligature was removed, and the animals were divided into groups/treatments: NT-receive no treatment; SRP-submitted only to SRP; DOX-submitted to SRP and DOX irrigation; LIL-submitted to SRP and LIL irradiation; and DOX + LIL-submitted to SRP treatments, DOX irrigation and LIL irradiation. The animals were sacrificed at 7, 15 and 30 days, and then, the analyses were performed. A lower concentration of Alpha-glycoprotein acid and Complement 3 was observed in the DOX + LIL group compared to all the other groups in all the periods, and for Complement 4 at 15 and 30 days (P < 0.01). A lower bone loss (BL) was observed in the DOX + LIL group compared to all the other groups in all the periods (P < 0.01). It can be concluded that LIL was effective in the reduction of proteins, and its association with DOX was effective in the reduction of proteins and BL, in the treatment of periodontal induction in rats.

Genetic polymorphisms in interleukin-6 and interleukin-1-beta were associated with dental caries and gingivitis.

OBJECTIVE: Evaluate the association between single nucleotide polymorphisms (SNPs) in Interleukin-6 (IL-6) gene (rs1800795) and in Interleukin-1-beta (IL-1ß) gene (rs1143627 and rs1143629) with dental caries and gingivitis in Brazilian children. MATERIAL AND METHODS: Three hundred and fifty-three children aged 8-11 years were included. Visible biofilm and gingival bleeding were evaluated by Community Periodontal Index. The International System for Detection and Assessment of Carious Lesions (ICDAS) was used to investigate dental caries. Real-time PCR evaluated SNPs in the DNA. Chi-square test, haplotype analysis and logistic regression were applied (alpha of 5%). RESULTS: The GG genotype in rs1800795 (IL-6) decreases the risk of gingivitis in a co-dominant model (p = .05; OR = 0.64). The GG genotype in rs1143627 (IL-1ß) reduces the risk of dental caries (Co-dominant model: ICDAS0 versus ICDAS1-6: p = .05; OR = 0.55. ICDAS0-2 versus ICDAS3-6: p = .02; OR = 0.49. Recessive model: ICDAS0 versus ICDAS1-6: p = .005; OR = 0.48. ICDAS0-2 versus ICDAS3-6: p = .004; OR = 0.45. Logistic regression: ICDAS0-2 versus ICDAS3-6: p = .05; OR = 0.24; CI 95%= 0.05-1.00). The GG genotype in rs1143629 was more frequent in ICDAS0 (p = .05; OR: 0.60). In the haplotype analysis, IL-1ß was associated with gingivitis. CONCLUSION: The rs1800795 in IL-6 gene was associated with gingivitis. The rs1143627 and rs1143629 in IL-1ß were associated with dental caries and gingivitis.

Clinical and Microbiological Analysis of Mechanical and Chemomechanical Methods of Caries Removal in Deciduous Teeth.

PURPOSE: This study evaluated carious tissue removal by mechanical and chemomechanical methods (Carisolv and Papacárie) through colony-forming unit (CFU) counts of Streptococcus mutans and Lactobacillus sp. Treatment acceptability, presence and level of pain, use of anesthesia, time required for caries removal and pain 24 h after treatment were also compared. MATERIALS AND METHODS: A clinical trial with 32 individuals who had at least two deciduous molars with active occlusal caries lesions were selected and randomly divided into two groups (I and II). One lesion in each individual was excavated with hand excavator only. The remaining lesions were excavated using modified hand excavation and Carisolv in group 1 or modified hand-excavation and Papacárie in group 2. Bacterial samples were taken from each caries lesion before and after treatment. RESULTS: All the methods reduced the amount of cultivable Streptococcus mutans and Lactobacillus sp. after treatment (p < 0.05) and no statistically significant difference was found between the groups (p > 0.05). There was 97% acceptability of treatments, and anesthesia was used in 14% of teeth. Pain was present 24 h after treatment in 6% of teeth. The mean times for caries removal by the mechanical and chemomechanical treatments were not statistically significantly different (p > 0.05). CONCLUSIONS: All treatments were found to effectively reduce bacterial counts (p < 0.05). There were no statistically significant differences (p > 0.05) among treatments or between clinical variables (p > 0.05).

Dental self-perception and clinical dental description of participants in the Open University programme for elderly people / Autopercepção e características clínico-odontológicas dos participantes da Universidade aberta a terceira idade

ABSTRACT Objective: This study verified both the self-perception and oral characteristics of a group of elderly participants of the Open University for the Elderly (UNATI). Methods: The sample consisted of a cross-sectional epidemiological study with elderly subjects (50 years of age or older), who attended the UNATI-UNIFAL/MG program. Data collection was carried out using a semi-structured questionnaire consisting of open- and closed-ended questions regarding oral health, its interference with self-esteem and nutrition, among other features. In addition, an application form based on the proposals by the Oral Health Survey 2010, was used. Univariate and multivariate descriptive analyses were performed. Results: The study sample consisted of 106 subjects (mean age of 62.4 years), of whom 59.4% had attended a dental appointment in the last year for routine and/or aesthetic examinations (38.7%). The clinical conditions showed that only 19.8% of the subjects were completely edentulous, an average DMFT of 26.1, and 37.7% used some kind of complete upper dentures, complete lower dentures, or both. Regarding self-perception of oral conditions, 34.9% considered it a regular perception, however in the applied statistics the presence of pain demonstrated a worse perception which was not correlated with teeth loss, presence of dentures and/or restored teeth. Conclusion: The self-perception of oral conditions is regular and the clinical and odontological characteristics evaluated revealed partial edentulous subjects with high DMFT. By evaluating the odontological aspects, it was observed that the majority of the subjects did not have difficulties to look for a dentist, they attended dental appointments in the last year and the preventive treatment had been the most required.

RESUMO Objetivo: Este estudo verificou a autopercepção, as características bucais e os aspectos odontológicos dos participantes da Universidade Aberta a Terceira Idade (UNATI). Métodos: Refere-se a um estudo epidemiológico transversal com indivíduos a partir de 50 anos de idade que frequentam o programa UNATI-UNIFAL/MG. O instrumento de coleta de dados consistiu em um questionário semiestruturado, composto por perguntas referentes à saúde bucal, interferência da mesma na autoestima e alimentação, entre outros. Além disso, foi utilizada uma ficha clínica baseada nas propostas do Levantamento em Saúde Bucal 2010. Foram realizadas análises descritivas, uni e multivariadas. Resultados: A amostra foi composta por 106 indivíduos, com idade média de 62,4 anos, dentre os quais 59,4% visitaram o cirurgião-dentista no último ano para exames de rotina e/ou estética (38,7%). As condições clínicas evidenciaram que apenas 19,8% dos indivíduos eram desdentados totais, o CPOD médio de 26,1 e 37,7% usava algum tipo de prótese total superior, inferior ou ambas. Quanto a autopercepção das condições bucais, 34,9% se refere regular, contudo, na estatística aplicada a presença de dor determinou uma pior percepção e não esteve correlacionada com a perda de dentes, presença de próteses e/ou dentes restaurados. Conclusão: A autopercepção das condições bucais é regular e as características clínico-odontológicas avaliadas revelaram indivíduos desdentados parciais com elevado CPOD. Ao avaliar os aspectos odontológicos a maioria não apresentou dificuldades ao procurar o cirurgião-dentista, visitaram esse profissional no último ano e o tratamento mais procurado por eles foi o preventivo.

Alterações bucais e o grau de dependência de idosos institucionalizados / Mouth changes and degree of dependency of institutionalized elderly / Alteraciones bucales y el grado de dependencia de ancianos institucionalizados

Este estudo objetiva relatar as alterações bucais e o grau de dependência de idosos institucionalizados. Um estudo observacional, transversal, baseado no levantamento da saúde bucal do Projeto Saúde Bucal Brasil (SB, 2010; Brasil, 2011), e Federação Dentária Internacional (FDI, 2009), sobre a classificação de dependência. O índice de ataque de cárie (CPO-D) dos idosos é elevado, edentulismo total expressivo, 52,9% são independentes, sendo que 80% faz a própria higienização bucal. Embora haja um expressivo número de idosos independentes que realizam a própria higiene bucal, os resultados indicam uma saúde bucal precária dos idosos institucionalizados.

Describe oral changes and level of dependency of institutionalized elderly. This cross-sectional observational study according to the rates adopted by the Oral Health Survey (SB 2010) and World Dental Federation on the classification of dependency. DMFT was high (31.0), total edentulism expressive, 52.9% were independente, 80% made their own oral hygiene. Although there is an evident great part of independent individuals who make their own oral hygiene, the results indicate that oral health of institutionalized elderly is very poor.

Este estudio objetiva relatar las alteraciones bucales y el grado de dependencia en ancianos institucionalizados. Un estudio observacional basado en el levantamiento de salud bucal (SB, 2010) y la Federación Dentaria Internacional (CPOD) alto, edentulismo total expresivo, el 52,9% de los ancianos independientes, siendo que el 80,0% hacía su propia higienización bucal. Aunque hay un evidente número de ancianos independientes y que realizan su propia higiene bucal, los resultados indican una salud bucal precaria de los ancianos institucionalizados.

Treatment of experimental periodontal disease by laser therapy in simvastatin-modified rats.

OBJECTIVE: The aim of this study was to evaluate low-level laser therapy (LLLT) as an adjuvant treatment for scaling and root planing (SRP) for the treatment of induced periodontitis in simvastatin-modified rats. MATERIAL AND METHODS: A total of 180 rats were evenly divided into two groups: Veh - receiving oral administration of polyethylene glycol (vehicle); S - receiving oral administration of Simvastatin. Periodontal disease was induced in both groups at the first mandibular molar. After seven days, the ligature was removed and the animals were divided into subgroups according to the following local treatments: NT - no treatment; SRP - scaling and root planing and irrigation with saline solution; and LLLT ¬- SRP and laser irradiation (660 nm; 0.03 W; 4 J). Ten animals in each subgroup/local treatment were euthanized at 7, 15 and 30 days. Samples of gingival tissue were processed to analyze the tissue oxidative damage and radiographic analysis. Levels of oxidative stress were analyzed by the expressions of Tripeptideglutathione (TG), Malondialdehyde (MDA) and Carbonylated Proteins (CP). RESULTS: The animals in S group had higher levels of TG and lower levels of MDA and CP compared with Veh group (p<0.05). Radiographically, in the intragroup analysis Veh and S, LLLT showed lower bone loss (BL) compared with NT and SRP, in all experimental periods (p<0.01). In addition, a lower BL was observed for the animals of Veh group treated with LLLT compared with treatment SRP in the S group, in all experimental periods. CONCLUSION: Within the limits of this study, we can conclude that LLLT was effective as adjuvant treatment for SRP protecting against the occurrence of oxidative tissue damages as well as for reducing alveolar bone loss in experimentally induced periodontitis simvastatin-modified rats.

Conclusion Within the limits of this study, we can conclude that LLLT was effective as adjuvant treatment for SRP protecting against the occurrence of oxidative tissue damages as well as for reducing alveolar bone loss in experimentally induced periodontitis simvastatin-modified rats.

Local application of statins in the treatment of experimental periodontal disease in rats.

OBJECTIVE: The objective of this study was to evaluate the local effects of statins as adjuvants for treatment by scaling and root planing (SRP) of periodontal disease induced in rats. MATERIAL AND METHODS: Ninety rats were used in the present experiment. Periodontal disease was induced in all animals using a cotton thread placed in the left first mandibular molar. After 7 days of induction, the bandage was removed and the animals were divided into three groups: 1) NT group (n=30), no treatment; 2) SRP group (n=30): SRP and irrigation with control gel; 3) S group (n=30) - SRP and irrigation with Simvastatin. Ten animals from each group were euthanized at 7, 15 and 30 days after treatment. Gingival biopsy specimens were processed to analyze the expression of matrix metalloproteinase 8 (MMP-8). The mandibles were removed and submitted to radiographic and laboratory processing for histometric analysis. RESULTS: The S group showed a significantly lower expression of MMP-8 compared to NT and SRP groups in all experimental periods. In the radiographic and histometric analyses between the groups, S group showed a significantly lower bone loss (BL) compared to NT and SRP groups in all experimental periods. CONCLUSIONS: Within the limits of this study, it can be concluded that locally applied statin was effective as an adjuvant treatment for SRP in rats with induced periodontal disease.

Local application of statins in the treatment of experimental periodontal disease in rats

Abstract Objective The objective of this study was to evaluate the local effects of statins as adjuvants for treatment by scaling and root planing (SRP) of periodontal disease induced in rats. Material and Methods Ninety rats were used in the present experiment. Periodontal disease was induced in all animals using a cotton thread placed in the left first mandibular molar. After 7 days of induction, the bandage was removed and the animals were divided into three groups: 1) NT group (n=30), no treatment; 2) SRP group (n=30): SRP and irrigation with control gel; 3) S group (n=30) - SRP and irrigation with Simvastatin. Ten animals from each group were euthanized at 7, 15 and 30 days after treatment. Gingival biopsy specimens were processed to analyze the expression of matrix metalloproteinase 8 (MMP-8). The mandibles were removed and submitted to radiographic and laboratory processing for histometric analysis. Results The S group showed a significantly lower expression of MMP-8 compared to NT and SRP groups in all experimental periods. In the radiographic and histometric analyses between the groups, S group showed a significantly lower bone loss (BL) compared to NT and SRP groups in all experimental periods. Conclusions Within the limits of this study, it can be concluded that locally applied statin was effective as an adjuvant treatment for SRP in rats with induced periodontal disease.

Efeitos da Sinvastatina como coadjuvante no tratamento da doença periodontal induzida em ratos / Effects of Simvastatin as supporting in the treatment of periodontal disease induced in rats

O estudo avaliou a Sinvastatina no tratamento da doença periodontal (DP) em ratos. Trinta e seis animais foram divididos em Grupo Controle (C) que receberam oralmente soro fisiológico e Sinvastatina (S) que receberam oralmente Sinvastatina. Após 24 horas, a DP foi induzida utilizando-se um fio de algodão na região dento-gengival dos primeiros molares inferiores esquerdos. Após 7 dias, a ligadura foi removida e os animais receberam raspagem e alisamento radicular (RAR) e irrigação com soro fisiológico. Os animais foram eutanasiados aos 7, 15 e 30 dias. Radiograficamente, o tratamento com RAR mostrou uma menor perda óssea (PO) no Grupo S comparado ao C em todos os períodos. Concluiu-se que a Sinvastatina associada à RAR foi efetiva na redução da PO em ratos.

The study evaluated simvastatin in the treatment of periodontal disease (PD) in rats. 36 animals were divided into control group (C) receiving oral saline and Simvastatin (S) who received oral simvastatin. After 24 hours the PD was induced using a cotton yarn in the dento-gingival area of the first left molar. After 7 days the ligature was removed and animals received scaling and root planing (SRP) and irrigation with saline. The animals were sacrificed at 7, 15 and 30 days. Radiographically treatment with SRP showed less bone loss (BL) in the S group compared to C in all periods. It was concluded that SRP associated with simvastatin was effective in reducing the BL in rats.a

Drug addiction: self-perception of oral health / Drogadição: Autopercepção em Saúde Bucal / Adicción a las drogas: auto percepción de la salud bucal

Objective: To report the self-perception of substance-abusing individuals who were in a recovery process regarding sociodemographic conditions and general and oral health. Methods: Descriptive cross-sectional study conducted in a recovery center for drug addiction in Alfenas, Minas Gerais, Brazil, in 2015, with 39 men aged over 18 years old. Data were collected using a semi-structured questionnaire that addressed: socioeconomic status, selfperception of general and oral health, access to dental care, relationship with the dentist, and other issues. In order to assess the self-perception of oral health, the variable was dichotomized into "satisfactory" and "unsatisfactory", which refer to what the individual acknowledges as a good or poor condition of oral health, using Fisher's exact test with 5% significance level. Results: Most frequent diseases were depression, 35.90% (n=14), insomnia, 35.9%, (n=14) and recurring headache (23.1%; n=9); however, 61.50% (n=24) of the participants reported not getting sick easily, which contrasts with their self-perception. Regarding oral health, only 30.50% (n=12) of the participants reported brushing their teeth three times a day; 53.80% (n=21) had dentinal hypersensitivity; 41.00% (n=16) had dry mouth and bad breath; 30.80% (n=12) claimed to have bruxism and reported having one or more loose teeth; 28.20% (n=11) reported clenching the teeth in an exaggerated way, and 33.30% (n=13) reported feeling tooth pain. Conclusion: The self-perception of individuals ­ under 30 years old, single, white or mulattos ­ regarding their general health was contradictory, as they rated it as good but have reported depression, insomnia and weight loss; additionally, oral health was considered poor with unsatisfactory conditions, which highlights the harmful effects of substance abuse.

Objetivos: Relatar a autopercepção de indivíduos drogaditos que se encontravam em estágio recuperatório, quanto às condições sociodemográficas, de saúde geral e bucal. Métodos: Estudo descritivo e transversal realizado em 2015 em um centro de triagem de recuperação de dependentes químicos, em Alfenas, MG, Brasil, com 39 internos do sexo masculino e acima de 18 anos. Por meio de um questionário semi-estruturado, investigaram-se temas referentes à condição socioeconômica, percepção dos internos em relação à própria saúde geral e bucal, acesso ao tratamento odontológico, relacionamento com o cirurgião-dentista, entre outros. A variável autopercepção em saúde bucal foi dicotomizada em "satisfatória" e "insatisfatória" para aplicação do teste Exato de Fisher, com nível de significância de 5%. Resultados: As doenças mais frequentes foram depressão, 35,90% (n=14), insônia, 35,9%, (n=14) e dor de cabeça recorrente (23,1%; n=9), apesar de 61,50% (n=24) dos internos afirmarem não ficar doentes, indicando autopercepção conflitante. Ao serem questionados sobre a frequência de escovação diária, apenas 30,50% (n=12) mencionaram três vezes ao dia, 53,80% (n=21) com sensibilidade dentinária; 41,00% (n=16) com sensação de boca seca e mal hálito; 30,80% (n=12) bruxismo, 28,20% (n=11) apertamento dental e 33,30% (n=13) dor em algum dente. Conclusão: A autopercepção dos internos analisados com menos de 30 anos, solteiros, brancos ou mulatos, quanto ao seu estado geral de saúde era contraditória, já que classificaram como boa, mas relataram depressão, insônia e perda de peso; e saúde bucal foi considerada ruim com condições insatisfatórias, que destacam os efeitos nocivos do uso de drogas.

Objetivo: Relatar la auto percepción de individuos drogadictos que estaban en proceso de recuperación, respecto las condiciones socio-demográficas y la salud general y bucal. Métodos: Estudio transversal y descriptivo realizado en un centro de recuperación para drogadicción en Alfenas, Minas Gerais, Brasil, en 2015, com 39 hombres con más de 18 años. Los datos fueron recogidos a través de un cuestionario semiestructurado que investigaba la posición socioeconómica, la auto percepción de la salud general y bucal, El acceso al cuidado dental, la relación con el dentista y otros temas. Para evaluar la auto percepción de la salud bucal la variable fue dividida en "satisfactoria" y "no satisfactoria" la cual refiere a los conocimientos del individuo sobre la buena o mala condición de salud bucal utilizando la prueba de Exacto de Fisher con El 5% de nivel de significancia. Resultados: Las enfermedades más frecuentes fueron la depresión con el 35,90% (n=14), el insomnio con el 35,9%, (n=14) y dolor de cabeza recurrente (23,1%; n=9); sin embargo, el 61,50% (n=24) de los participantes relataron no enfermarse con facilidad lo que contrasta con su auto percepción. Respecto a la salud bucal, solamente el 30,50% (n=12) de los participantes relataron cepillar los dientes tres veces al día; El 53,80% (n=21) tuvieron hipersensibilidad dental; el 41,00% (n=16) tuvieron la sensación de boca seca y mal aliento; El 30,80% (n=12) reclamaron de bruxismo y relataron tener uno o más dientes perdidos; el 28,20% (n=11) relataron apretar los dientes de manera exagerada y el 33,30% (n=13) relataron tener dolor de diente.
