ABSTRACT Objective: To determine the prevalence and risk factors associated with dental caries in Brazilian preschool children aged 2 to 5 years. Material and Methods: The following independent variables were evaluated: dental caries, dental trauma, and malocclusions. Data were analyzed using the Mann-Whitney test and Poisson regression (p<0.05). Results: The prevalence of dental caries in preschoolers was 55.1%. Child age, family income, maternal education, and tooth color alteration from trauma were significantly associated with dental caries (p<0.05). The final adjusted multivariate model showed a significant association between maternal education and dental caries; children of mothers with low education were 1.89 times more likely to have caries (PR: 1.89; 95%CI: 1.40-2.55) (p<0.01). Children with tooth color change from trauma were more likely to have dental caries (PR: 1.69; 95%CI: 1.22-2.34 (p=0.001). Conclusion: Child age, family income, maternal education, tooth discoloration and discoloration color are risk factors for the development of caries disease in children. Also, children of mothers with low educational levels have a higher chance of developing dental caries.

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.

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.

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.

Abstract Low intensity laser can be used as a promising alternative in the treatment of periodontal disease. 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.

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.

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.

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
Résumé
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. Conclusión: La auto percepción de los individuos - por abajo de los 30 años, solteros, blancos o mulatos - respecto su salud general fue contradictoria ya que clasificaron como buena aunque reportaron la depresión, el insomnio y La pérdida de peso; además, la salud bucal fue considerada pobre con condiciones no satisfactorias, las cuales resalta los efectos nocivos de la substancia abusiva.

Introduction: The dentin hypersensitivity associated with gingival recession is an occurrence of high prevalence in the clinical routine of dentists. Coverage of exposed root surfaces represents a challenge for periodontal treatment. Objective: The purpose of the present study is to describe an approach for adjacent gingival recession treatment using a combination of two surgical techniques: the subepithelial connective tissue graft (SCTG) with a laterally positioned double flap. Case report: This surgical treatment was conducted in a 45-yearold female patient who complained of sensitivity when brushing the lower right teeth. Clinical and radiographic examinations showed gingival recessions (Miller Class III) with traumatic origin promoted for tooth brushing and the presence of thin periodontium in the region. In addition, interproximal bone loss was noted on vestibular face of the right mandibular second premolar and mesial root of the right mandibular first molar. At 12 postoperative months, it was observed that the association of the two surgical techniques promoted an almost complete coverage of the gingival recessions, an increased keratinized gingival band and the elimination of initial dentin hypersensitivity. Conclusion: The appropriate choice of techniques and patient compliance to the periodontal support therapy led to treatment success and periodontal health maintenance in the region during the whole follow-up period.

Objective - The aim of this study was to evaluate the effects of Lumiracoxib as adjunctive treatment on induced periodontitis in rats. Material and Methods - Periodontal disease was induced in the first mandibular molar of sixty rats. After 7 days, the ligature was removed and all animals were submitted to scaling and root planning (SRP) along with local irrigation with saline solution and were divided into 2 groups: SRP (n = 30) - received subcutaneous injections of 1 mg/kg of body weight/day of saline solution for three days and; SRP + L (n = 30) - received subcutaneous injections of 1 mg/kg of body weight/day of Lumiracoxib for three days. Ten animals in each group were killed at 7, 15 and 30 days. The distance between the cementumenamel junction and the height of alveolar bone crest in the mesial surface of the mandibular left first molars was determined in millimeters foreach radiograph. The radiographic values were statistically analyzed (ANOVA and Tukey tests, p<0.05). Results - In Group SRP + L, the radiographic analysis showed less bone loss (p<0.05) than in Group SRP at 7, 15 and 30 days, respectively. Conclusions - Within the limits of this study it can be concluded that subcutaneous application of Lumiracoxib was a beneficial adjunctive treatment for periodontal diseases induced in rats.
Objetivo - O objetivo deste estudo foi avaliar os efeitos do Lumiracoxibe como tratamento coadjuvante na periodontite induzida em ratos. Materiais e Método - A doença periodontal foi induzida no primeiro molar inferior de sessenta ratos. Após 7 dias, a ligadura foi removida e todos os animais foram submetidos à raspagem e alisamento radicular (RAR), juntamente com irrigação local de solução salina e foram divididos em 2 grupos: RAR (n = 30) - receberam injeções subcutâneas de 1 mg / kg de peso corporal / dia de soluçãosalina por três dias e, RAR + L (n = 30) - receberam injeções subcutâneas de 1 mg / kg de peso corporal / dia de Lumiracoxibe por três dias. Dez animais de cada grupo foram sacrificados aos 7, 15 e 30 dias. A distância entre a junção cemento-esmalte e a altura da crista óssea alveolar na superfície mesial do primeiro molar inferior esquerdo foi determinada em milímetros para cada radiografia. Os valores radiográficos foram analisados estatisticamente (ANOVA e teste de Tukey, p <0,05). Resultados - No grupo RAR + L, a análise radiográfica mostrou menor perda óssea (p <0,05) comparado ao grupo RAR aos 7, 15 e 30 dias, respectivamente. Conclusão - Dentro dos limites desteestudo pode-se concluir que a aplicação subcutânea de Lumiracoxibe foi um tratamento coadjuvante benéfico para a doença periodontal induzida em ratos.

Objetivo: Avaliar por meio de análises histométrica e imuno-histoquímica os efeitos da terapia fotodinâmica antimicrobiana (aPDT) no tratamento alveolar prévio à colocação de implantes, em alvéolos de dentes de ratos portadores ou não de doença periodontal induzida. Material e método: Trinta e dois ratos foram utilizados no estudo. A doença periodontal foi induzida nos primeiros molares inferiores esquerdos. Decorridos sete dias, foi realizada a remoção da ligadura e a exodontia dos primeiros molares inferiores direitos e esquerdos. A seguir, os animais foram divididos em dois grupos de 16 animais, de acordo com os tratamentos realizados nos alvéolos dentais antes da instalação do implante imediato: DM-debridamento mecânico (DM), irrigação com 1 mL de soro fisiológico seguida de instalação do implante; aPDT-DM, irrigação com 1 mL de azul de toluidina O (TBO) e, após 1 minuto, irradiação com laser em baixa intensidade (LLLT). Oito animais de cada grupo foram eutanasiados aos 15 e 30 dias. Os espécimes foram processados laboratorialmente para análises histométrica do contato osso-implante (BIC) e imuno-histoquímica. Os dados histométricos foram estatisticamente analisados (Teste Kruskall-Wallis e Dunn p < 0,05). Resultado: Na análise dos tratamentos, os resultados demonstraram que houve maior BIC nos implantes instalados em alvéolos não contaminados tratados com aPDT (p < 0,05) e maior imunorreatividade à OPG no tecido ósseo tratado com aPDT. Conclusão: A aPDT mostrou-se efetiva no controle da perda óssea em áreas não contaminadas e aumentou a atividade metabólica e a atividade das células ósseas nos alvéolos irradiados previamente à instalação dos implantes.
Objective: The aim of this study is to evaluate by histometric and immunohistochemistry analysis the effects of antimicrobial photodynamic therapy (aPDT) in alveolar prior to placement of mini-implants in animals with or without induced periodontal disease. Material and method: Thirty-two rats were used. Periodontal disease (PD) was induced by ligature in the lower left first molar. After 7 days of PD evolution, it was performed removal of the ligature and extraction of the left lower first molars in all animals. Thus, animals were divided into 2 groups (n = 16) according to the treatments in the dental alveolus before immediate implant installation: MD (control) : mechanical debridement (MD), irrigation with 1 mL of saline solution followed by implant installation; aPDT-MD, irrigation with 1 mL of Toluidine Blue-O and low intensity laser (LLLT) and implant installation. Eight animals from each group were euthanized at 15 and 30 days after the installation of mini-implants. Specimens were processed for histologic, immunohistochemical and histometric analysis. The histometric data were processed for statistical analysis (Kruskall-Wallis and Dunn test; p < 0.05). Result: In treatment analysis, results indicated thatthere was a greater BIC in implants installed in uncontaminated alveolus treated with a PDT ( p < 0.05) and greater imuno-reactivity to OPG in bone issue treated with aPDT. Conclusion: The aPDT proved to be effective in bone loss control in no contaminated area and it has increased the bone loss and metabolic activity in alveolus irradiated prior to implant installation.

A percepção da condição bucal é um importante indicador de saúde, pois sintetiza a condição real de saúde, as respostas subjetivas, os valores e as expectativas culturais. O estudo avaliou a importância da saúde bucal segundo a percepção de pacientes internados em um hospital da cidade de Araçatuba (SP). Foi aplicado um questionário semi-estruturado para a coleta de dados e utilizado para análise estatística o programa Epi Info 2000. Os resultados mostraram que metade dos pacientes haviam realizado a última visita ao cirurgião-dentista em um período compreendido entre seis a doze meses devido a problemas periodontais (35 por cento) e cárie dentária (20 por cento). Observou-se que, embora todos os pacientes considerassem ter uma "boa" higiene bucal, o tratamento periodontal foi identificado como o de maior necessidade entre os pacientes (67,93 por cento). A presença do cirurgião-dentista no corpo clínico hospitalar foi considerada por todos os entrevistados como fundamental para contribuir no cuidado integral à saúde dos pacientes hospitalizados. Quanto ao papel do dentista em um hospital, a grande maioria dos pacientes (90,63 por cento) afirmou ser o "cuidar dos dentes". Assim, conclui-se que todos os pacientes têm conhecimento do quão é importante a manutenção das condições adequadas de saúde bucal, principalmente em pacientes hospitalizados.
The perception of oral condition is an important health indicator as it synthesizes the condition of objective health, subjective answers, cultural values and expectative. The study evaluated the importance of oral health according to the perception of inpatients of a hospital unit at Araçatuba city, São Paulo State. A partially structured questionnaire was used to collect data. The program Epi Info 2000 was used to statistics analysis. The results show that half of patients affirmed that visited a dental surgeon on a period between 6 and 12 months due to periodontal problems (35 percent) and dental caries (20 percent). It was observed that although all patients consider to have a good oral hygiene, the periodontal treatment was identified like the more necessary among them (67.93 percent). The presence of a dental surgeon at the hospital clinical group was considered by all the patients essential to collaborate with the integral care of health of inpatients. About the role of dental surgeon in a hospital, the majority of patients (90.63 percent) affirmed to be the act of "caring on the teeth". So, it is possible to conclude that all the patients know the importance of the maintenance of oral health appropriated conditions specially of inpatients.

OBJECTIVE: The aim of this study was to compare subgingival irrigation with tetracycline hydrochloride (TTC-HCL) as adjunctive treatment to scaling and root planning (SRP) on induced periodontitis in rats. MATERIAL AND METHODS: In 60 rats, periodontal disease was ligature-induced at the mandibular left first molar. After 7 days, the ligature was removed and all animals were submitted to SRP, and divided into 2 groups according to the following treatment: C (n=30) - subgingival irrigation with 1 mL of saline; T (n=30) - subgingival irrigation with 1 mL of TTC-HCL (50 mg/mL). Ten animals in each group were euthanized at 7, 15 and 30 days posttreatment. The histometric values were statistically analyzed (p<0.05). RESULTS: In the histometric analysis, at 7, 15 and 30 days, Group T (0.72±0.05 mm², 0.57±0.14 mm², 0.62±0.07 mm²), showed less bone loss (p<0.05) than Group C (1.35±0.25 mm²; 1.40±0.31 mm²; 1.29±0.27 mm²), respectively. CONCLUSIONS: Subgingival irrigation with TTC-HCL was an effective adjunctive treatment for periodontal disease induced in rats.

OBJECTIVE: The aim of this study was to assess radiographically the effect of photodynamic therapy (PDT) as an adjunctive treatment to scaling and root planing (SRP) on induced periodontitis in dexamethasone-induced immunosuppressed rats. MATERIAL AND METHODS: The animals were divided into 2 groups: ND group (n=60): saline treatment; D group (n=60): dexamethasone treatment. In both ND and D groups, periodontal disease was induced by the placement of a ligature in the left first mandibular molar. After 7 days, ligature was removed and all animals received SRP, being divided according to the following treatments: SRP: saline and PDT: phenothiazinium dye (TBO) plus laser irradiation. Ten animals per treatment were killed at 7, 15 and 30 days. The distance between the cementoenamel junction and the height of the alveolar bone crest in the mesial surface of the mandibular left first molars was determined in millimeters in each radiograph. he radiographic values were analyzed statistically by ANOVA and Tukey's test at a p value <0.05. RESULTS: Intragroup radiographic assessment (ND and D groups) showed that there was statistically signifcant less bone loss in the animals treated with PDT in all experimental periods compared to those submitted to SRP. Intergroup radiographic analysis (ND and D groups) demonstrated that there was greater bone loss in the ND group treated with SRP compared to the D group treated with PDT at 7 and 30 days. CONCLUSION: PDT was an effective adjunctive treatment to SRP on induced periodontitis in dexamethasone-induced immunosuppressed rats.

O objetivo do presente estudo foi avaliar a influência da terapia fotodinâmica (PDT) como coadjuvante ao tratamento não cirúrgico da doença periodontal (DP) experimentalmente induzida em ratos tratados ou não com nicotina. Cento e oitenta ratos foram divididos em 2 grupos de 90 animais cada. Os do Grupo Controle (C) receberam aplicações subcutâneas de soro fisiológico; os do Grupo Nicotina (N) receberam aplicações subcutâneas de nicotina. As injeções foram realizadas duas vezes ao dia e iniciadas 30 dias antes da indução da DP, continuando pós tratamento periodontal até os respectivos períodos de sacrifício. A DP foi induzida através da colocação de ligadura com fio de algodão na região dento-gengival dos primeiros molares inferiores esquerdos. Após 7 dias da indução, a ligadura foi removida e, os animais foram divididos em subgrupos de acordo com os seguintes tratamentos locais: Tratamento I - raspagem e alisamento radicular (RAR) e irrigação com soro fisiológico; Tratamento II - RAR e irrigação com azul de toluidina O (TBO) e Tratamento III RAR, irrigação com TBO e, após 1 minuto, aplicação do laser em baixa intensidade (LLLT) (GaAsAl, 660 nm, 4J), realizando a PDT. Dez animais de cada subgrupo foram sacrificados aos 7, 15 e 30 dias. Os espécimes foram processados laboratorialmente e analisados histológica, histométrica e imunoistoquímicamente. Aos 7, 15 e 30 dias, em ambos os grupos, o tratamento RAR apresentou um tecido conjuntivo desorganizado, com elevado número de neutrófilos e discreto número de fibroblastos. O tecido ósseo apresentou áreas de necrose e trabéculas ósseas finas. Nos períodos de 7 e 15 dias os animais dos grupos C e N, tratados pela PDT, apresentaram um tecido conjuntivo bem desenvolvido com moderado número de fibroblastos, discreto infiltrado inflamatório crônico e tecido ósseo moderadamente desenvolvido. Aos 30 dias, apresentaram um ligamento periodontal íntegro, organizado e com fibras colágenas paralelas entre si. O tecido...
The aim of this study was to evaluate the influence of photodynamic therapy (PDT) as an adjunct to non-surgical treatment of periodontal disease (PD) experimental induced in rats treated with or without nicotine. One hundred and eighty rats were divided into 2 groups of 90 animals each. Control group (C) received subcutaneous infusions of saline, group of Nicotine (N) received subcutaneous infusions of nicotine. The injections were performed twice a day and started 30 days before induction of PD, continuing after periodontal treatment until their period of sacrifice. PD was induced by placing cotton ligature in the dento-gingival region of the left lower first molars. After 7 days of induction, the ligature was removed and the animals were divided into subgroups according to the following local treatments: treatment I - scaling and root planing (SRP) and irrigation with saline; Treatment II - SRP and irrigation with O toluidine blue (TBO) and Treatment III - SRP, irrigation with TBO and 1 minute after application of low intensity laser therapy (LLLT) (GaAlAs, 660 nm, 4J), performing the PDT. Ten animals of each subgroup were sacrificed at 7, 15 and 30 days. The laboratory specimens were processed and analyzed histologically, histometrically and immunohistochemically. At 7, 15 and 30 days in both groups, treatment SRP showed a disorganized tissue with high numbers of neutrophils and a small number of fibroblasts. The bone tissue showed areas of necrosis and trabecular bone thin. At 7 and 15 days the animals in groups C and N, treated by PDT, showed a well developed connective tissue with a moderate number of fibroblasts, mild chronic inflammatory infiltrate and bone moderately developed. At 30 days, they presented an intact periodontal ligament, and organized collagen fibers in parallel. The connective tissue was well-developed, healthy and with no inflammatory infiltrate. The intragroup analysis showed that the animals in group C treated with PDT had less...

O presente estudo teve por objetivo avaliar radiograficamente, os efeitos provenientes da adaptação da ligadura durante a indução da doença periodontal em ratos. Para este estudo foram usados 30 ratos. No primeiro molar inferior foi adaptada uma ligadura a qual foi distribuída de forma randômica, entre o lado direito e esquerdo. O lado sem ligadura foi utilizado como controle (negativo). Logo após a adaptação da ligadura, esta foi removida. Os animais foram sacrificados no período de 0, 3 e 7 dias, tendo dez animais por período. Desta forma as mandíbulas foram removidas, separadas e fixadas em formol. As hemimandíbulas foram radiografadas e analisadas pelo sistema de imagem digital Digora, onde à distância da união cemento-esmalte à crista óssea alveolar foi mensurada em mm por um traçado linear. Os dados coletados não indicaram diferença estatisticamente significante entre os grupos e períodos experimentais analisados pelo teste T de student (p>0,05). Dentro dos limites deste estudo e da metodologia utilizada podemos concluir que a ligadura não traumatiza os tecidos periodontais e por si só não leva ao desenvolvimento da doença periodontal em ratos.
