ABSTRACT

OBJECTIVE: To evaluate retention of intraoral fluoride in biofilm and saliva, an experimental dentifrice containing hydrocolloid (tara gum) was used as a controlled-release system for fluoride (F). MATERIALS AND METHODS: In a triple-blind randomized crossover trial with washout, 18 individuals used the following different dentifrices for a week: 100-TGF (sodium fluoride NaF associated with tara gum, 1100 mg/L), 50-TGF (50% NaF associated with tara gum + 50% free NaF, 1100 mg/L), PC (free NaF, 1100 mg/L), TG (with tara gum and without F), and placebo (without F or tara gum). On the seventh day of dentifrice use, biofilm was collected at 1 and 12 h, and saliva was collected up to 60 min and 12 h after the last toothbrushing. F concentrations were determined by physico-chemical analysis of fluoride using the hexamethyldisiloxane-facilitated diffusion technique. Data were subjected to two-way analysis of variance (repeated measures) and Spearman's correlation coefficient (p < 0.05) testing. RESULTS: No significant difference was observed with the same dentifrice regarding F retention in biofilm at 1 and 12 h after toothbrushing for the 100-TGF, placebo, and TG groups (p > 0.05). The highest area under the curve values in saliva were found for the 50-TGF, 100-TGF, and PC groups. CONCLUSION: The dentifrice containing hydrocolloid as a controlled-release system for F promoted F retention in the oral cavity, even at 12 h after brushing. CLINICAL RELEVANCE: Hydrocolloid added to dentifrices as a controlled-release system for F might contribute to a higher anti-caries effect. TRIAL REGISTRATION: NCT02809014.

ABSTRACT

The aim of this study was to evaluate the prevalence of temporomandibular disorders (TMD) signs and symptoms, its correlation with gender, parafunctional habits, emotional stress, anxiety, and depression and its impact on oral health-related quality of life (OHRQL) in college preparatory students at public and private institutions in João Pessoa, Paraíba (PB). The sample consisted of 303 students. Presence of TMD symptoms was determined by an anamnesis questionnaire containing questions related to the presence of parafunctional habits and emotional stress. A simplified clinical evaluation protocol was used. Anxiety and depression were determined with the Hospital Anxiety and Depression (HAD) scale and the OHRQL using the short version contained in the Oral Health Impact Profile (OHIP-14). The Chi-square, Fisher Exact, Mann Whitney, and Kruskal-Wallis tests were performed. Presence of signs and symptoms of TMD was statistically associated (p ≤ 0,05) with female gender, parafunctional habits, emotional stress, and anxiety, and represented greater impairment of the OHRQL. The physical pain domain was the most affected. The increased prevalence of signs and symptoms of TMD among college preparatory students indicates that there is a need for education and clarification among teachers and students to improve early diagnosis and to prevent the problem.


O objetivo deste estudo foi avaliar a prevalência de sinais e sintomas de disfunção temporomandibular (DTM), sua associação com gênero, hábitos parafuncionais, tensão emocional, ansiedade e depressão e, o seu impacto sobre a qualidade de vida relacionada com a saúde oral (QVRSO) em estudantes pré-vestibulandos de instituições públicas e privadas de João Pessoa/PB. A presença de sintomas de DTM foi determinada através de questionário anamnésico, contendo também questões relacionadas à presença de hábitos parafuncionais e tensão emocional. Um protocolo simplificado de avaliação clínica foi aplicado. Ansiedade e depressão foram determinadas através da escala Hospital Anxiety and Depression (HAD) e, a QVRSO avaliada por meio da versão resumida do Oral Health Impact Profile (OHIP-14). Foram realizados testes de Qui-quadrado, Exato de Fisher, Mann Whitney e Kruskal-Wallis. A presença de sinais e sintomas de DTM foi estatisticamente associada ao gênero feminino, hábitos parafuncionais, tensão emocional e ansiedade, e representou maior comprometimento da QVRSO. A elevada prevalência de sinais e sintomas de DTM entre os estudantes pré-vestibulandos sinaliza a necessidade de divulgação e esclarecimento de professores e alunos visando o diagnóstico precoce e a prevenção.

ABSTRACT

Introdução: O papel da oclusão como fator etiológico das disfunções temporomandibulares (DTMs) tem sido um assunto polêmico e ainda controverso. Objetivo: Avaliar a correlação entre sinais e sintomas da disfunção temporomandibular e a severidade da má oclusão. Método: Foram avaliados 135 estudantes de Odontologia da UFPB. A presença de DTM foi estimada através do Índice Anamnésico de Fonseca (DMF) e de questões objetivas sobre seus sintomas. Os estudantes também foram submetidos a um protocolo resumido de avaliação clínica de DTM. A avaliação dos fatores oclusais foi realizada através do Índice de Prioridade de Tratamento (IPT) aplicado a modelos de gesso dos arcos dentários superior e inferior. As diferenças entre as médias do IPT relacionadas aos sinais e sintomas de DTM foram determinadas por meio dos testes t e One-way ANOVA. As correlações entre os fatores oclusais e a DTM foram determinadas a partir de correlação de Pearson. Resultado: A severidade da má oclusão, segundo o IPT, não influenciou no surgimento de DTM e de sinais clínicos musculares ou articulares, e na necessidade de tratamento. A má oclusão de classe II, trespasse vertical acentuado e dentes girados foram estatisticamente correlacionados à necessidade de tratamento e aos sinais clínicos de DTM. Conclusão: Em modelos multifatoriais, como na fisiopatologia da DTM, a oclusão pode desempenhar um papel de cofator na predisposição ou perpetuar as diferentes formas de DTM, não devendo ser considerada fator principal. .


Introduction: The role of occlusion as an etiologic factor of temporomandibular disorders (TMD) has been polemic and still controversial. Objective: To evaluate the correlation between signs and symptoms of temporomandibular disorders and severity of malocclusion. Method: A total of 135 undergraduate dental students from Federal University of Paraíba were evaluated. The presence of TMD was estimated by Fonseca's Anamnestic Index and objective questions about symptoms were addressed. Students were also submitted to a summarized protocol for clinical evaluation of TMD. The evaluation of occlusal factors was performed using the Treatment Priority Index (TPI) applied to plaster casts corresponding to upper and lower dental arches. The differences between the means of IPT related to signs and symptoms of TMD were determined by t tests and One-way ANOVA. Correlations between occlusal factors and TMD were determined by Pearson correlation. Result: According to the TPI, the severity of the malocclusion did not influence the onset of TMD, muscle or joint clinical signs and need for treatment. Class II malocclusion, marked overbite and rotated teeth were statistically correlated with the need for treatment and clinical signs of TMD. Conclusion: In multifactor models as in the pathophysiology of TMD, occlusion can play a role as a co-factor in predisposing or perpetuating the different forms of TMD. As such, it should not be considered a major factor. .

ABSTRACT

Realizar o levantamento das jurisprudências deresponsabilidade civil promovidas pelo paciente contra oCirurgião-Dentista (CD) nos estados brasileiros no período entre2006 e 2011. Material e Métodos: Os dados foram coletadosnos sites dos Tribunais da Justiça de cada estado, sendorelativos à obrigação assumida, ao seu fundamento, ao agentee as especialidades mais emanadas. Realizou-se o cálculo daexperiência processual a partir do número de processos pornúmero de CDs inscritos nos Conselhos Federal e Regionais,procedendo-se a análise descritiva. Resultados: Foramlevantadas 1046 jurisprudências, com São Paulo e Rio deJaneiro apresentando os maiores números de processos.Quanto ao tipo de obrigação do CD, 9,51% consideraram anatureza de resultado, enquanto em 77,57% essa informaçãonão foi citada. A responsabilidade do CD foi definida comosubjetiva em 14,31% das jurisprudências, mas em 70,33% amesma não foi classificada. O coeficiente de experiênciaprocessual brasileiro foi de 4,23 e os estados que demonstraramos maiores valores foram: Rio de Janeiro (11,75) e DistritoFederal (6,81). Em relação às especialidades odontológicas,as mais citadas foram implantodontia (11,53%) e prótese (9,3%).Conclusão: O coeficiente de experiência processual brasileiroé alto e, apesar da ausência de informações em parte dasjurisprudências, percebe-se que a responsabilidade docirurgião-dentista normalmente é interpretada como subjetiva,de origem contratual, com obrigação de resultado...


To survey the case law of civil liability undertakenby patients against dentists in Brazilian states between 2006and 2011. Material and Methods: Data were collected fromwebsites of the Courts of Justice of each state, taking intoaccount: obligation’ nature, its ground, the agent and dentalspecialties more involved. We carried out the calculation ofcoefficient of legal experience by dividing the number of casesper number of dentists registered at Federal and RegionalCouncils. Then, descriptive analysis was conducted. Results:The sample comprised 1046 jurisprudence and Sao Pauloand Rio de Janeiro showed the highest numbers of cases.Regarding the type of obligation assumed by dentists, 9.51%considered the result as the final aim of dentist-patient relation,while in 77.57% this information was not cited. Dentist’sresponsibility was defined as subjective in 14.31% ofjurisprudence, but in 70.33% it was not classified. The Braziliancoefficient of legal experience was 4.23 and the states thatshowed the highest values †were Rio de Janeiro (11.75) andthe Federal District (6.81). Regarding dental specialties, dentalimplants (11.53%) and prosthetics (9.3%) were the most cited.Conclusion: The Brazilian coefficient of legal experience ishigh and, despite the lack of information on some jurisprudence,it is clear that the responsibility of the dentist is usuallyinterpreted as subjective, as source contract, with an obligationof result...
