RESUMO
Abstract Objective: To estimate the prevalence of sleep bruxism and its association with oral health conditions in schoolchildren. Material and Methods: Cross-sectional study carried out in public schools of Tubarão, SC, Brazil with students aged 10 to 15 years. The oral examination was performed in classrooms by dental surgeons, using the WHO criteria. Data on malocclusions, caries and dental trauma, fluorosis, bleeding gums and the presence of dental calculus were collected. For the diagnosis of bruxism, the criterion of the American Academy of Sleep Medicine was adopted. The chi-square test was used to assess the association between sleep bruxism and oral health conditions. Prevalence ratios and confidence intervals were estimated by Poisson regression with robust estimator. Results: A total of 389 students were examined. The prevalence of sleep bruxism was 22.0%. Schoolchildren with malocclusion, increased overjet and dental calculus showed a statistically higher and independent prevalence of 9.0% (p=0.003), 6.0% (p=0.006) and 19.0% (p<0.001), respectively. Conclusion: Prevalence of sleep bruxism was 22% in the study population and was associated with malocclusions, particularly increased overjet, and the presence of dental calculus.

ABSTRACT Objective: To study the impact of dental trauma on the oral health-related quality of life among Brazilian students. Methods: A cross-sectional study involving a representative sample of students of the public schools (n = 435) in a city in southern Brazil was carried out. Data on dental trauma were collected through oral examinations using the O'Brien's criteria (1993) restricted to fractures and avulsions. The Brazilian version of the Oral Impacts on Daily Performances (OIDP) was used in order to collect data on the impact of oral health-related quality of life. Bivariate and multivariate analysis were performed through Poisson log-linear regression with robust estimator with significance levels set at p <0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated. Results: The prevalence of dental trauma was 7.2%, and it was associated with the following dimensions: performing daily activities [(PR = 3.52 (95% CI, 1.06-11.75)] (p = 0.040), and speaking [(PR = 3.67 (95% CI, 1.24-10.86)] (p = 0.019) after adjusting for sex, age, dental caries and malocclusion. Conclusion: The prevalence of dental trauma found among this population was low, but significantly associated with oral health-related quality of life.
RESUMO Objetivo: Estudar o impacto do trauma dental na qualidade de vida relacionada a saúde oral entre escolares brasileiros. Métodos: Foi realizado estudo transversal envolvendo uma amostra representativa de escolares (n = 435), em uma cidade no sul do Brasil. Os dados sobre trauma dental foram coletados através de exames orais utilizando os critérios do O'Brien (1993), restritas a fraturas dentais e avulsões. A versão brasileira dos impactos no desempenho diário (OIDP) foi utilizado para recolher dados sobre o impacto na qualidade de vida relacionada à saúde bucal. O teste do qui-quadrado foi utilizado para a análise bivariada com níveis de significância de p <0,05. As razões de prevalência (RP) e intervalos de confiança (95%) foram estimados utilizando regressão de Poisson log-linear com um estimador robusto. Resultados: A prevalência de trauma dental foi de 7,2%, e foi associado com as seguintes dimensões: realização de atividades cotidianas [(RP = 3,52 (IC 95%, 1,06-11,75)] (p = 0,040), e falar [(PR = (IC 95%, 1,24-10,86) 3,67] (p = 0,019) após o ajuste para sexo, idade, cárie dentária e maloclusão. Conclusão: A prevalência de traumatismo dentário encontrado entre esta população era baixa, mas significativamente associada à qualidade relacionada à saúde bucal de vida.
RESUMO
PURPOSE: To estimate the prevalence and severity of malocclusion and test a possible association with negative impacts on quality of life of schoolchildren in Tubarão, Brazil. MATERIALS AND METHODS: A cross-sectional study was conducted on a representative sample (n = 389) of schoolchildren. Data on oral health-related quality of life were obtained through the Oral Impacts on Daily Performance (OIDP) scale. The malocclusion indicator was the Dental Aesthetic Index (DAI). Prevalence ratios were estimated using log-linear Poisson regression with a robust estimator. RESULTS: The prevalence of class II, III, and IV malocclusion was 57.3%. The most common dental condition was overjet greater than 3 mm. Girls and older schoolchildren showed statistically significantly higher prevalence of all classes of malocclusion. There were no statistically significant associations between the most frequent malocclusions and dimensions of the impact indicator, except for the presence of overjet greater than 3 mm that was associated the 'cleaning teeth' dimension. CONCLUSION: The prevalence of malocclusion was high, but was not statistically significantly associated with impact on oral health-related quality of life.

BACKGROUND: Osteoradionecrosis of the jaw (ORNJ) is the most severe and complex sequel of head and neck radiotherapy (RT) because of the bone involved, it may cause pain, paresthesia, foul odor, fistulae with suppuration, need for extra oral communication and pathological fracture. We treated twenty lesions of ORNJ using low-level laser therapy (LLLT) and antimicrobial photodynamic therapy (aPDT). The objective of this study was to stimulate the affected area to homeostasis and to promote the healing of the oral mucosa. METHODS: We performed aPDT on the exposed bone, while LLLT was performed around the bone exposure (red spectrum) and on the affected jaw (infrared spectrum). Monitoring and clinical intervention occurred weekly or biweekly for 2 years. RESULTS: 100% of the sample presented clinical improvement, and 80% presented complete covering of the bone exposure by intact oral mucosa. CONCLUSION: LLLT and aPDT showed positive results as an adjuvant therapy to treat ORNJ.

Trauma in the anterior teeth is a relatively common occurrence during childhood, having as main consequence teeth with incomplete root development and open apices. Patient, male, leucoderma, 10 years old, attended the Dental Clinic of the Southern University of the State of Santa Catarina, reporting as main complaint fracture in the crown of element 11. After clinical and radiographic examination, it was possible to identify the incomplete apexogenesis of this tooth and the presence of necrotic pulp. Aiming to stimulate neoformation of mineralized tissue at the dental apex, the calcium hydroxide based dressing was used. He remained for eight months, always with radiographic control. Apexification was observed radiographically and proved through the use of an instrument introduced inside the canal. The use of calcium hydroxide as intracanal medication for eight months stimulated mineralized tissue neoformation in the apical region of element 11 and allowed endodontic treatment.
RESUMO
BACKGROUND: This study aimed to estimate the prevalence of mandibular asymmetry and investigate some associated factors. METHODS: Tomographic images of 952 individuals aged from 18 to 75 years old were analyzed. The investigated outcome was mandibular asymmetry. The explanatory variables included gender, age, absence of posterior teeth, and sagittal jaw relationship of the individuals. Statistical analyses included the chi-squared and the Poisson regression with robust variance. RESULTS: Mandibular asymmetry was present in 17.4% of the sample (95% confidence interval 15.2-20.0). In the bivariate analysis, there was an association between the variables age and sagittal jaw relationship with mandibular asymmetry (Pâ=â0.026 and Pâ=â0.018, respectively). However, in the adjusted regression model, the association with age was not maintained, occurring only an association between sagittal jaw relationship and mandibular asymmetry (Pâ=â0.045), with significant difference between individuals with skeletal Class II and skeletal Class III (Pâ=â0.013). CONCLUSION: Mandibular asymmetry was not independently associated with sex, age, or absence of posterior teeth. The only verified independent association was between mandibular asymmetry and sagittal jaw relationship.

INTRODUCTION: Facial skeletal asymmetry is commonly found in humans and its main characteristic is menton deviation. The literature suggests that occlusal and masticatory problems arising from tooth absence could be related to the development of such asymmetries. OBJECTIVE: The aim of this cross-sectional study was to estimate the prevalence of mandibular skeletal asymmetries and to investigate its association with posterior tooth absences. METHODS: Tomographic images of 952 individuals aged from 18 to 75 years old were used. Asymmetry was the analyzed outcome, and it was categorized into three groups according to gnathion displacement in relation to the midsagittal plane (relative symmetry, moderate asymmetry, and severe asymmetry). Patients were sorted by the presence of all posterior teeth, unilateral posterior tooth absence, or bilateral posterior tooth absence. Chi-square test with a significance level of 5% was used to verify the association between posterior tooth absence and asymmetry. RESULTS: Results show relative symmetry present in 55.3% of the sample, as well as the prevalence of 27.3% for moderate mandibular asymmetry and 17.4% for severe asymmetry. Moderate and severe mandibular asymmetries occurred in a higher proportion in patients with unilateral posterior tooth absence. However, there was no statistically significant difference between the analyzed groups (p = 0.691). CONCLUSIONS: In this study, mandibular asymmetries did not present any association with the absence of teeth on the posterior area of the arch.

RESUMO Introdução: a assimetria esquelética facial é comum em humanos, sendo o desvio do mento sua principal característica. É sugerido, na literatura, que problemas oclusais e mastigatórios advindos das ausências dentárias teriam relação com o desenvolvimento dessas assimetrias. Objetivo: o objetivo deste estudo transversal foi estimar a prevalência de assimetrias esqueléticas mandibulares e investigar sua associação com as ausências dentárias posteriores. Métodos: foram utilizadas imagens tomográficas de 952 indivíduos, com idade entre 18 e 75 anos. A assimetria foi o desfecho analisado, sendo categorizada em três grupos, de acordo com o desvio do gnátio em relação ao plano sagital mediano: simetria relativa, assimetria moderada e assimetria severa. Os indivíduos foram agrupados segundo a presença de todos os dentes posteriores, ausência dentária posterior unilateral ou ausência dentária posterior bilateral. Para verificar a associação entre a ausência dentária posterior e a assimetria, foi utilizado o teste Χ2, ao nível de significância de 5%. Resultados: os resultados mostraram que a simetria relativa esteve presente em 55,3% da amostra, bem como uma prevalência de 27,3% para a assimetria mandibular moderada e 17,4% para assimetria severa. As assimetrias mandibulares moderada e severa ocorreram em maior proporção nos indivíduos com ausência dentária posterior unilateral; entretanto, não houve diferença estatisticamente significativa entre os grupos (p = 0,691). Conclusões: nesse estudo, as assimetrias mandibulares em adultos não apresentaram associação com a ausência de dentes na região posterior da arcada dentária.

Objective: To estimate the impact of dental caries on the oral health-related quality of life of school children of public schools of Tubarão, Santa Catarina, Brazil. Material and Methods: A cross-sectional study on a sample of 42310-15 years old students was carried out. The prevalence of dental caries, dental trauma and malocclusion was observed by oral examination based on WHO criteria. The Oral Impact on Daily Performance indicator was used to collect data about the impact on quality of life related to children's oral health. The Chi-square test was used for bivariate analysis with significance levels set at p<0.05. Prevalence ratios (PR) and confidence intervals (95%) were estimated using log-linear Poisson regression with a robust estimator. Results: The prevalence of dental caries was 55.5%. The prevalence of impact on oral health related quality of life was 45.6%. OIDP dimensions significantly associated with dental caries were eating [PR = 1.45 (95%CI 1.06; 2.00)] (p = 0.021), sleeping [(PR = 2.29 (95%CI 1.15; 4.56)] (p = 0.018) and performing daily activities [PR = 2.57 (95%CI 1.06; 6.22)] (p = 0.036) after adjusting for gender, age and presence of dental trauma and malocclusion. Conclusion: Dental caries was found to be significantly associated with oral health-related quality of life of children in activities such as eating, sleeping, and performing daily activities.

The aim of this study was to evaluate the mesiobuccal root of maxillary first molars, according to the root canal configuration, prevalence and location of isthmuses at 3 and 6 mm from the apex, comparing cone-beam computed tomography (CBCT) analysis and cross sectioning of roots by thirds. Images of the mesiobuccal root of 100 maxillary first molars were acquired by CBCT and then roots were cross-sectioned into two parts, starting at 3 mm from the apex. Data were recorded and analyzed according to Weine's classification for root canal configuration, and Hsu and Kim's classification for isthmuses. In the analysis of CBCT images, 8 root canals were classified as type I, 57 as type II, 35 as type III. In the cross-sectioning technique, 19 root canals were classified as type I, 60 as type II, 20 as type III and 1 as type IV. The classification of isthmuses was predominantly type I in both CBCT and cross-sectioning evaluations for sections at 3 mm from the apex, while for sections at 6 mm from the apex, the classification of isthmuses was predominantly types V and II in CBCT and cross-sectioning evaluations, respectively. The cross-sectioning technique showed better results in detection of the internal morphology of root canals than CBCT scanning.

Resumo: O objetivo do presente estudo foi avaliar a raiz mésio-vestibular de primeiros molares superiores, de acordo com a configuração do canal radicular e com a prevalência e localização de istmos a 3 e a 6 mm do ápice, comparando a análise realizada em tomografia computadorizada de feixe cônico (TCFC) com a técnica de seccionamento transversal por terços. Foram obtidas imagens tomográficas das raízes mésio-vestibulares de 100 primeiros molares superiores, e em seguida, as raízes foram seccionadas em dois segmentos, iniciando nos 3 mm a partir do ápice. Os dados foram analisados de acordo com a classificação de Weine para configuração de canais radiculares, e de acordo com a classificação de Hsu e Kim para avaliação dos istmos. Na análise das imagens das TCFCs, 8 canais radiculares foram classificados como tipo I, 57 como tipo II, e 35 como tipo III. Na técnica de seccionamento transversal, 19 canais radiculares foram classificados como tipo I, 60 como tipo II, 20 como tipo III, e 1 como tipo IV. Na avaliação dos istmos, houve predominância do tipo I tanto na TCFC quanto na técnica de seccionamento transversal a 3 mm do ápice. Entretanto, a 6 mm do ápice, a classificação dos istmos foi predominantemente tipo V e II, na avaliação em TCFC e na técnica de seccionamento transversal, respectivamente. A técnica de seccionamento transversal demonstrou melhores resultados na detecção da morfologia interna dos canais radiculares avaliados do que a TCFC.

Objetivo: Avaliar o conhecimento dos formandos em Odontologia sobre Resíduos dos Serviços de Saúde (RSS) gerados em consultórios odontológicos. Material e Métodos: Estudo descritivo e transversal com abordagem quantitativa. O universo eleito foram os alunos concluintes do curso de Odontologia das faculdades do estado de Santa Catarina, Brasil. O cálculo amostral foi determinando em 198 alunos. Os dados coletados foram digitados em Excel 2010 (Microsoft) e os resultados expressos por frequências absolutas e relativas. Resultados: Embora existam oito faculdades de Odontologia no estado de Santa Catarina, duas não aceitaram participar do estudo e uma não havia turma concluinte. Houve participação de 138 (73,0%) formandos. Dentre os alunos participantes, 92,2% afirmaram saber o que são resíduos de serviços de saúde. Sobre a forma de descarte, 76,8% estavam cientes do correto descarte da liga de amálgama, 77,5% do hipoclorito de sódio, 82,6% sobre os líquidos utilizados no processamento de radiografias, 95,7% dos materiais perfuro-cortantes, 20,3% do invólucro da película radiográfica, 68,1% sobre o descarte dos Equipamentos de Proteção Individual, 77,5% dos papéis de receituário e 33,3% dos resíduos de gesso. Sobre acondicionamento, 83,3% sabiam como proceder com o mercúrio residual e 95,7% com o líquido residual de revelador e fixador. Quanto às legislações vigentes para os profissionais da saúde, cirurgiões-dentistas e consultórios odontológicos, o conhecimento dos acadêmicos foi insuficiente sobre o assunto. Conclusão: Embora os formandos de Odontologia de Santa Catarina saibam sobre o que é e como devem acondicionar e descartar os RSS, o conhecimento foi insatisfatório sobre as legislações vigentes no Brasil sobre a temática, sendo necessária maior atenção durante a formação acadêmica.(AU)
Aim: To evaluate the knowledge of dental students regarding Health Service Waste (HSW). Methods: This is cross-sectional study with a quantitative approach. The defined realm was of all final year dental schools students from state colleges in Santa Catarina, Brazil. The sample calculation was determined in 198 students. The collected data were entered into Excel 2010 (Microsoft), and the results were expressed as absolute and relative frequencies. Results: Although there are eight dentistry colleges in the state of Santa Catarina, two refused to participate in the study and one did not have final year class. This study counted on the participation of 138 (73.0%) dental students. Among the participants, 92.2% reported that they knew what health service wastes were. Regarding how to dispose of these wastes, 76.8% reported being aware of the correct disposal of dental amalgam, 77.5% of sodium hypochlorite, 82.6% of the liquids used in the processing of radiographs, 95.7% of perforating-cutting materials, 20.3% of radiographic film wrappers, 68.1% of the disposal of Personal Protective Equipment, 77.5% of prescription papers, and 33.3% of plaster waste. Regarding packaging, 83.3% reported knowing how to proceed with the proper disposal of residual mercury and 95.7% with the residual liquid from developers and fixers. As for the existing laws for health professionals, dentists, and dental offices, knowledge of academians proved to be inadequate on the subject. Conclusion: Although the final year dental students in Santa Catarina knew about what it is and how they should package and dispose of HSW, knowledge was unsatisfactory as regards the applicable Brazilian laws on the subject, requiring greater attention during academic education.(AU)

To measure dental anxiety in children, determine its association with behavior exhibited during treatment and evaluate the use of informative and aversive behavior management techniques.Material and Methods:Across-sectional study was carried out with 51 children aged 6-12 years submitted to restorative dental procedures at the pediatric dental clinic of the Franciscano University Center (Brazil) between May and December 2013. Anxiety was measured using the Venham Picture Test and behavior during treatment was analyzed using the Frankl Behavior Scale. Variables were submitted to descriptive statistics. The chi-square test was used to determine associations between anxiety and categorical variables, considering associations with p-value p ≤ 0.05 to be statistically significant.Results:Twelve children (23.5%) exhibited anxiety prior to dental procedure. Anxiety was not significantly associated with age (p=0.669), gender (p=0.478), behavior during treatment (p=0.915) or behavioral management techniques (p=0.701). Moreover, no significant association was found between changes in the level of anxiety after procedure and the behavior management techniques used during treatment (p=0.828).Conclusion:A high percentage of children exhibited dental anxiety. However, anxiety prior to dental procedure was not associated with any of the variables analyzed and no association was found between changes in the level of anxiety after procedure and the informative or aversive behavior management techniques used during treatment...

Objetivo: avaliar as taxas de sucesso e sobrevivência de implantes há cinco anos ou mais em função. Material e métodos: pacientes tratados com implantes de titânio (Implacil De Bortoli, São Paulo, Brasil) na Fundecto (USP), no período de 1998 a 2008 foram incluídos neste estudo. Os implantes foram classificados individualmente, de acordo com um rigoroso critério de sucesso. Também foram levados em consideração o formato e o tipo de plataforma dos implantes. Resultados: a taxa de sobrevivência dos implantes tipo hexágono externo (n=357) e interno (n=140) foi de 99,4% e 99,3%, respectivamente. Já com relação aos implantes cônicos (n=88) e cilíndricos (n=409), a taxa de sobrevivência foi de 100% e 99,3%, respectivamente. A taxa de sucesso para implantes tipo hexágono externo e interno foi de 90,8% e 93,6%, respectivamente. Implantes cônicos obtiveram 90,9%, enquanto que implantes cilíndricos apresentaram 91,7% de taxa de sucesso. Conclusão: de acordo com o presente estudo, a taxa geral de sobrevivência dos implantes foi de 99,4%, enquanto a taxa de sucesso foi de 91,5%.
Objective: to assess success and survival rates from implants in function for five or more years. Material and methods: patients treated with osseointegrated implants (Implacil De Bortoli, Sao Paulo, Brazil) at Fundecto (USP), from 1998 to 2008, were included in this study. Implants were individually classified using strict success criteria. For further analysis, data were obtained regarding implants platform and implants macro design. Results: survival rates for external (n=357) and internal hexagon implants (n=140) were 99,4% and 99,3%, respectively. Regarding tapered (n=88) and cylindrical implants (n=409), survival rates were 100% and 99,3%, respectively. Success rates for external and internal hexagon implants were 90,8% and 93,6%. Tapered implants had 90,9% and cylindrical implants presented 91,7% of success rates. Conclusion: according to this retrospective study, the overall survival rate was 99,4% and the overall success rate was 91,5%.

AIM: The aim of this study was to verify two different types of interfaces in Morse taper connection implants, relating the mechanical resistance to a loosening torque that is required to separate or move the prosthetic abutment. MATERIAL AND METHODS: Ten Morse taper connection implants and their respective abutments were divided into two groups (n = 5), DH (double hexagon) interface and OI (octagonal implant) interface. A standard insertion of implants was performed in a stainless steel base, where each abutment received a sequence of two consecutive tightening torques at a 10-minute interval, followed by a loosening torque, which was measured using a digital torque gauge. The Student's t-test with a 5% significance level was used for data analysis. RESULTS: The results showed a statistically significant difference in the loosening torque values compared with DH torque values (p < 0.05). However, the difference between tightening and loosening torque values was not statistically significant in the OI group (p = 0.465). CONCLUSION: The study concluded that there was a difference in the torque required to loosen the abutment screws between the DH group and the OI group, with the latter showing better results.

Com o aumento da expectativa de vida da população, torna-se importante garantir aos idosos maior longevidade com qualidade de vida. Este estudo objetivou estimar a contribuição das condições sociodemográficas na percepção de qualidade de vida em idosos participantes dos grupos de convivência. Foram realizadas entrevistas com 141 idosos, sobre questões relacionadas a variáveis sociodemográficas e autoavaliação da qualidade de vida. O X ² foi utilizado para testar associações. Para o domínio físico, as variáveis foram inseridas em um modelo de regressão logística múltipla não condicional. Resultados: 73% dos idosos responderam estar satisfeitos com sua qualidade de vida e 69,5% avaliaram sua saúde como boa. No domínio ambiental, a renda familiar e a escolaridade mostraram-se associadas. No domínio físico, a renda familiar, a escolaridade, a condição de estar sozinho e a idade de 80 anos ou mais mostraram-se associadas. A maioria da população investigada classificou sua qualidade de vida como boa, mas a idade avançada mostrou-se estatisticamente associada à pior percepção de qualidade de vida no domínio físico
