Pathologies in peri-implant tissues are common and may disturb long-term implant supported rehabilitation. We aimed to evaluate the occurrence of such peri-implant diseases and their associated factors in this study. Peri-implantitis and mucositis were diagnosed based on clinical and radiological findings. Statistical analysis was performed with the X
2 and logistic regression. Peri-implant mucositis and peri-implantitis were observed in 43.4% and 13.8% of patients with implants evaluated, respectively. Univariate analysis found associations with systemic changes (P =.016; yes), medication use (P =.010; yes), implant location (P <.0001; upper jaw), implant region (P =.008; posterior), previous augmentation procedure (P =.023; yes), time of prostheses use (P <.0001; >2 years), keratinized mucosa (P <.0001; absence); and gingival bleeding index (P =.005; >30%). In the multiple analysis, independent predictors were: >2 years of prostheses use (P <.0001; PR = 1.720), upper jaw location (P <.0001; PR = 1.421), gingival bleeding index >30% (P =.001; PR = 1.496), and use of medication (P <.0001; PR = 1.261). The frequency of peri-implant pathologies is high (approximately 57.2%) with several aspects of the occurrence being related to the patients' prosthesis. Prostheses type and the complexity of rehabilitation are worth highlighting. Factors include the location of the dental implant, gingival bleeding index, patient's use of medication(s), and the time of prostheses use. [ABSTRACT FROM AUTHOR]- Published

Aims: To evaluate the effectiveness of counseling on pain intensity and oral health-related quality of life (OHRQoL) in temporomandibular disorders (TMD) patients. Methods: Fifty female patients diagnosed with TMD were divided into two groups: a group of waiting list patients (control group) and a group of patients who received counseling therapy (experimental group) involving education about etiologic factors, avoidance of parafunctional habits, and sleep, as well as dietary advice. All patients were evaluated at baseline and 7, 15, 30, and 60 days later. Patients reported pain intensity using a visual analog scale (VAS), and the Oral Health Impact Profile (OHIP-14) was used to assess the impact of pain on OHRQoL. Statistical analyses were performed using the split-plot analysis of variance (SPANOVA) design, with post hoc Student t tests for independent samples and for dependent samples, adopting a significance level of P < .05. Results: The control group consisted of 24 female patients with a mean age of 39.96 ± 13.93 years, and the experimental group consisted of 26 female patients with a mean age of 35.15 ± 10.78 years. Counseling was considered effective for reducing pain intensity, with a significant improvement observed at 7 days (P < .001). Counseling was also responsible for a significant improvement in the impact of TMD on OHRQoL at all follow-up time points analyzed (P < .001). When comparing the groups, a significant difference was observed for both pain intensity and TMD impact on OHRQoL during follow-up (P < .05). Conclusion: Counseling seems to significantly improve pain and OHRQoL in patients. [ABSTRACT FROM AUTHOR]

- Abstract
Objectives: To evaluate periodontal parameters of abutment teeth and interproximal sites, in patients with mandibular class I Kennedy Removable Partial Dentures (RPD), after 4 years of periodontal treatment.Methods: Fourteen patients with periodontal disease were treated and evaluated for the following parameters: plaque index (PI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), clinical attachment loss (CAL) and keratinized mucosa (KM). Parameters were compared between abutment teeth with direct and indirect retainers at all time-points. Periodontal maintenance was recorded at 6, 18 and 48 months. Data were analyzed using the Friedman and Wilcoxon Tests.Results: Most patients (n=11; 78.6%) included were female and had a mean age of 66 years (± 7.8). After 48 months, a significant reduction was only observed in PI for both abutment teeth; in contrast, PD, GR, CAL and KM all increased by the end of the study. BOP increased at 48 months for the abutment teeth with direct retainers. The distal site of the abutment teeth with direct retainers presented higher values for GR and CAL.Conclusions: Non-surgical periodontal therapy was effective during the first 18 months, but periodontal conditions were worse at 48 months after therapy. The distal sites of abutment teeth with direct retainers presented the worst periodontal conditions. [ABSTRACT FROM AUTHOR]- Published

Purpose: To evaluate the effect of basic periodontal treatment on clinical periodontal parameters associated with abutment teeth of patients with mandibular Kennedy class I removable partial dentures (RPD) 18 months after treatment. Materials and Methods: Thirty patients with periodontal disease were treated and evaluated according to the following periodontal parameters: visible plaque index (VPI), bleeding on probing (BOP), probing depth (PD), gingival recession (GR), clinical attachment loss (CAL), and keratinized mucosa (KM). These parameters were compared between abutment teeth with direct and indirect retainers at baseline, and after 6 and 18 months. Data were analyzed by Friedman Test and Wilcoxon Test for all variables. Results: Most patients (n = 26; 86.7%) included in the study were female and had a mean age of 61 years (±7.54). Results showed that VPI and BOP decreased over time, and that VPI values were higher in abutment teeth with direct retainers (p = 0.001). There was a reduction in PD after 6 months, which was maintained up to 18 months. In general, abutment teeth with direct retainers had significantly higher values for PD, GR, and CAL (p = 0.029). Data also indicated that the parameters for VPI, BOP, and PD improved; however, abutment teeth with direct retainers presented smaller improvements, compared with abutment teeth with indirect retainers, which presented significant improvements for almost all variables. Conclusion: Periodontal treatment and oral hygiene care of patients were adequate for maintenance of adequate periodontal conditions, regardless of the use of prostheses. [ABSTRACT FROM AUTHOR]

- Abstract
Dento-alveolar traumas are one of the most frequent injuries to teeth, mainly affecting the upper incisors due to their exposed position in the dental arch. In such cases, esthetics, function and phonetics of anterior teeth may be compromised. Furthermore, when there is involvement of the biological width, there is often a poor prognosis. This case report describes the multidisciplinary approach to tooth fragment re-attachment in a fracture with biological width violation. The patient presented with an oblique crown fracture in the maxillary right lateral incisor, extending from the buccal to palatal side, as well as a biological width invasion. The re-establishment of the biological width was obtained by periodontal surgery to achieve clinical-crown lengthening and tooth fragment re-attachment with a glass fibre post to increase retention. After 3 years of follow-up, the rehabilitated lateral incisor remains in good condition, with satisfactory esthetic and periodontal health.

OBJETIVO: esta revisão de literatura visa avaliar, através de literatura específica, a sensibilidade e especificidade do exame de ressonância magnética (RM) para o diagnóstico dos desarranjos internos da articulação temporomandibular (ATM). METODOLOGIA: tanto artigos que utilizaram ATM de cadáveres para comparar achados anatômicos aos achados de ressonância magnética (RM), como artigos que compararam achados clínicos com achados de RM foram utilizados. Através dos achados desses artigos, as propriedades de sensibilidade e especificidade da RM para o diagnóstico de desarranjos internos da ATM foram calculadas. Com isso, a confiabilidade e a aplicabilidade do exame de RM no diagnóstico dos desarranjos internos da ATM foram discutidas. RESULTADOS: encontrou-se sensibilidade de 90% e especificidade de 88% da RM para desarranjos internos da ATM. CONCLUSÃO: o exame de RM de ATM possui ótima sensibilidade e especificidade para o diagnóstico dos desarranjos internos da ATM. Porém, tal exame deve ser solicitado com cautela, apenas nos casos onde a imagem seja indispensável para o plano de tratamento.OBJECTIVE: the aim of this paper is to review the literature concerning the reliability and applicability of magnetic resonance imaging (MRI) in the diagnosis of temporomandibular joint (TMJ) internal disorders. METHODS: articles that have used TMJ from cadavers to compare MRI findings with anatomic findings, as well as some papers that have compared clinical findings with MRI findings were evaluated. According to the findings identified on these articles, the MRI sensitivity and specificity properties for the TMJ internal disorders diagnosis were calculated. Then, the MRI reliability and applicability for the TMJ internal disorders diagnosis were discussed. RESULTS: 90% of sensitivity and 88% of specificity were found. CONCLUSION: the TMJ MRI presents good sensitivity and specificity for the TMJ internal disorders diagnosis. But dentists should beware and request this exam only in cases where MRI will be essential to the treatment planning.

Objectives: The objective of this review was to assess the literature for evidence investigating the role of TGF-β in temporomandibular joint disease with osteoarthritis.Method: An electronic and manual search was carried out on the databases, MEDLINE/PubMed, Cochrane Library, Web Of Science, and EMBASE, from 1975 to December 2015 by two independent evaluators to identify clinical and laboratory trials in English.Results: The search produced 693 records. Following a process of selection based on certain criteria, eight articles were included.Discussion: This systematic review suggests that TGF-β administration alone does not result in joint regeneration; other factors may be involved, such as TGF-β receptor expression ,and TGF-β receptor mutations that do not allow a correct transduction, resulting in TGF-β deficiency. The anabolism induced by this growth factor is also able to neutralize the catabolic processes that are elevated in osteoarthritis. Therefore, further studies are essential to determine how the concentration of TGF-β in the temporomandibular joints acts as a potential marker for the development of degenerative conditions.

Background: The evaluation of possible differences in the distribution or characteristics of palpation-induced pain in the masticatory muscles could be valuable in terms of diagnostic assessment. The aim of this study was to evaluate the impact of different combinations of anterior temporalis (AT) and masseter palpation-induced pain in the diagnostic of temporomandibular disorder (TMD), primary headaches and bruxism. Material and Methods: A total of 1200 dental records of orofacial pain adult patients were analyzed. The outcomes were dichotomously classified (presence/absence) as following: a) AT and/or masseter palpation-induced pain; b) myogenous TMD; c) temporomandibular joint (TMJ) arthralgia (arthrogenous TMD); d) migraine; e) tension-type headache (TTH); f) self-reported bruxism. Binomial logistic regression model (α = 5%) was applied to the data considering the palpation-induced muscle pain as the dependent variable. Results: Mean age (SD) were 35.7 years (13.4) for 635 included dental records (83% females). Myogenous and arthrogenous TMD, migraine, TTH and bruxism were mainly associated with, respectively, masseter palpationinduced pain (p<0.001 - OR=5.77, 95%CI 3.86-8.62), AT or masseter palpation-induced pain (p<0.001 - OR=2.39, 95%CI 1.57-3.63), bilateral AT palpation-induced pain (p<0.001 - OR=2.67, 95%CI 1.64-4.32), masseter and AT palpation-induced pain (p=0.009 - OR=1.62, 95%CI 1.12-2.33) and bilateral masseter palpation-induced pain (p=0.01 - OR=1.74, 95%CI 1.13-2.69). Conclusions: Palpation-induced pain in the masticatory muscles may play a role in the differential diagnosis among painful TMD, primary headaches and bruxism. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Material and Methods Results Conclusions To evaluate whether a two‐piece abutment is equivalent to a one‐piece in peri‐implant esthetics, patients' satisfaction, and oral health–related quality of life (OHRQOL) for implant‐supported anterior single crown placement.Thirty implants were allocated sequentially: 15 in the one‐piece abutment group (OP) and 15 in the two‐piece abutment group (TP). Peri‐implant esthetics were evaluated by the pink esthetic score (PES) at temporary crown insertion (T1), after tissue conditioning (T2), and at 30 days after the final crown insertion (T3). OHRQOL was measured using the OHIP‐14 and satisfaction was evaluated using the visual analog scale (VAS) at baseline, T1, and T3. Treatment was considered equivalent if the 95% coefficient interval (CI) for mean difference in PES was between −1.5 and +1.5 points. Statistical analysis was performed using Mann–Whitney, SPANOVA, and Student's t‐test, with Sidak's posttest, adopting p < 0.05.No differences were found between the groups for any variable and during follow‐up. A significant increase in OHRQOL and satisfaction was observed at T3, when compared to baseline (p < 0.05) for both groups. Significant improvements in peri‐implant esthetics were also observed throughout the treatment, particularly after tissue conditioning (p < 0.05). Primary and secondary outcomes were evaluated for equivalence, and both abutment types were considered equivalent following the insertion of the temporary crowns.Two‐piece abutment was equivalent to one‐piece abutment for peri‐implant esthetics, quality of life, or the satisfaction of patients rehabilitated with metal‐free single crowns. Tissue conditioning and final crown insertion appear to play a role in improving these outcomes. [ABSTRACT FROM AUTHOR]

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES A incidência e prevalência das disfunções temporomandibulares (DTM) as caracterizam como um problema de saúde pública, tornando necessária a criação de políticas públicas adequadas no diagnóstico, avaliação e tratamento destas condições no Brasil. Diante disso, o objetivo deste estudo é a elaboração de um instrumento de diagnóstico de fácil aplicação, a ser validado, possibilitando levantamento epidemiológico acerca da prevalência de DTM na população brasileira. Trata-se de um estudo de construção de instrumento, que seguiu em sua elaboração evidências de validade. O instrumento foi dividido em duas partes: um questionário e um protocolo clínico. O instrumento foi baseado em instrumentos pré-existentes na literatura e na experiência clínica do grupo de pesquisa formada para este trabalho. O instrumento passou pelas etapas de evidências de validade baseadas no conteúdo e evidências de validade baseadas no processo de resposta. Como resultados houveram 3 versões do instrumento. A primeira contendo o questionário com 09 questões e 12 itens do protocolo clínico; após a fase de validação de conteúdo o instrumento foi reduzido para 05 questões e o protocolo clínico com 08 itens (2ª versão). A 2ª versão foi validada pelo processo de resposta e manteve-se a quantidade de itens, acrescentando algumas instruções para o futuro aplicador do instrumento. Dessa maneira, o produto deste trabalho foi um instrumento de diagnóstico intitulado Instrumento De Diagnóstico Epidemiológico para Disfunção Temporomandibular – IDE/DTM. As evidências de validade efetuadas até o momento permitiram relevantes modificações e tornaram este instrumento mais conciso e adequado ao seu objetivo. The incidence and prevalence of temporomandibular disorders (TMD) characterize them as a public health issue, becoming necessary to create adequate public policies in the diagnosis, evaluation and treatment of these conditions in Brazil. Therefore, the objective of this study was to develop an easy to apply diagnostic tool, to be validated, allowing an epidemiological survey regarding TMD prevalence in the Brazilian population. This is a study of instrument construction, which followed the steps of evidence of validity. The instrument was divided into two parts: a questionnaire and a clinical protocol. The instrument was based on pre-existing instruments in the literature and on the clinical experience of the research group responsible for this study. The instrument went through the Validity Evidence Based on the Content and on the Response Process steps. As a result, there were 3 versions of the instrument. The first comprising a questionnaire with 09 questions and a 12 items clinical protocol; after the content validation phase, the instrument was condensed to 5 questions and 8 items clinical protocol (2nd version). The 2nd version was validated by the response process and the number of items was maintained, but some instructions for the future surveyor were included. Thus, the product of this study is a diagnostic instrument entitled Epidemiological Diagnostic Instrument - IDE / DTM. The evidence of validity allowed relevant modifications and made this instrument more concise and appropriate to its objective.

Estética periimplantar ,Condicionamento tecidual ,Satisfação ,Intermediário protético - Abstract
Objetivos: Avaliar a influência do tipo de intermediário protético e do condicionamento tecidual sobre a estética de coroas unitárias provisórias sobre implantes instalados na região do sorriso. Material e Métodos: Trinta implantes foram alocados sequencialmente: 15 foram reabilitados provisoriamente sobre um intermediário protético pré-fabricado em titânio (GT) e 15 sobre um intermediário protético preparável provisório (GP). Em ambos os grupos foi realizado condicionamento tecidual (CT) pela técnica não-cirúrgica de pressão gradual e a estética periimplantar foi avaliada antes e após esse processo, por meio do Pink Esthetic Score (PES). O PES também foi aplicado no dente homólogo à reabilitação. A satisfação estética foi analisada pela escala visual analógica (EVA) após o procedimento de CT. Dados clínicos da mucosa gengival também foram coletados. Resultados: 22 pacientes, totalizando 24 implantes, concluíram o estudo, sendo 14 implantes do GT e 10 do GP. A estética periimplantar antes e após o CT, bem como a satisfação dos pacientes foi semelhante entre os grupos, p>0,05. Diferenças significativas foram encontradas para os valores de PES antes e após o CT, e para a comparação com o dente homólogo em ambos os grupos, p0,05. Conclusão: O intermediário protético não influenciou nem no processo de condicionamento tecidual e nem na satisfação dos pacientes. A etapa de condicionamento tecidual foi capaz de melhorar os resultados estéticos periimplantares, entretanto, a estética gengival dos dentes naturais homólogos apresenta resultados significativamente superior. Objective: To evaluate the influence of prosthetic abutment and tissue conditioning on the esthetics of single implants’ temporary crowns. Materials and Methods: Thirty implants were allocated sequentially: fifteen implants were provisionally rehabilitated with a titanium prefabricated prosthetic abutment (GT) and 15 with a provisional preparable prosthetic abutment (GP). In both groups, tissue conditioning (TC) was performed by the non-surgical gradual pressure technique and peri-implant aesthetics were assessed before and after this process, using the Pink Esthetic Score (PES). PES was also applied on homologous tooth. Aesthetic satisfaction was assessed using the visual analog scale (EVA) after the conditioning process. Clinical data on the gingival mucosa were also collected. Results: 22 patients (24 implants) completed this study, 14 implants from GT and 10 from GP. Peri-implant aesthetics before and after TC, as well as patient satisfaction was similar between groups, p> 0.05. Significant differences were found for PES values before and after TC, and for comparison with the homologous tooth in both groups, p 0.05. Conclusion: The prosthetic abutment seems not influence neither the TC process nor patient satisfaction. The TC step is able to improve the peri-implant aesthetic results, however, the gingival aesthetics of the natural teeth is still significantly greater.

Objetivo: Avaliar a sobrevida clínica de laminados cerâmicos em zircônia ultratranslúcida e os impactos desse tratamento na qualidade de vida do paciente. Materiais e métodos: O estudo é um ensaio clínico controlado e randomizado, duplo cego (paciente e avaliador) e de caráter longitudinal. A amostra foi de 82 laminados cerâmicos: 39 laminados em dissilicato de lítio para o grupo controle e 43 em zircônia ultratranslúcida para o grupo experimental. O tratamento restaurador foi realizado por cirurgiões-dentistas participantes do projeto de extensão “Próteses Fixas Metal-Free”. A coleta de dados foi realizada por um único examinador nos períodos de avaliação de 1 mês (T1), 6 (T2), 12 (T3), 24 (T4), 36 (T5) e 48 (T6) meses. Quanto ao impacto na qualidade de vida, um questionário modificado OIDP (Oral Impact of Daily Performances) foi usado. A análise da longevidade clínica foi feita através dos critérios modificados de Ryge conferidos com espelho clínico e explorador. Os dados referentes a sobrevida dos laminados de diferentes materiais foram representados graficamente através da curva de Kaplan-Meier. Os escores dos critérios de Ryge, e impacto na qualidade de vida do paciente foram a analisados descritivamente. As espessuras médias para cada terço (cervical, medial e incisal) foram comparadas entre os diferentes materiais através do teste Anova 1 fator. Para análise estatística o nível de significância estabelecido foi de 5%. Resultados: A taxa de sobrevida clínica foi de 100% para os laminados de ambos os materiais. Apenas o critério descoloração marginal obteve uma classificação diferente de A. O escore B foi apresentado por 9 laminados de dissilicato de lítio e 2 de zircônia ultratranslúcida, Não houve nenhuma interferência negativa do tratamento na qualidade de vida dos indivíduos. Falar e relaxar foram as atividades em que o tratamento menos interferiu. Não houve diferença estatisticamente significante para as espessuras dos laminados entre os dois tipos de materiais. Conclusão: O tratamento com laminados confeccionados em zircônia ultratranslúcida apresenta desempenho clínico similar aos casos tratados em dissilicato de lítio. Objective: to evaluate the clinical survival of ceramic laminates in ultra-translucent zirconia and the impacts of this treatment on the patient's quality of life. Materials and methods: The study was analyzed as a controlled, randomized, double-blind (patient and evaluated) clinical trial with a longitudinal character. The sample studied was 82 ceramic laminates divided into two groups according to the type of material, 39 laminates in lithium disilicate for the control group and 43 in ultra-translucent zirconia for the experimental group. The restorative treatment was carried out by dentists participating in the extension project “Metal-Free Fixed Prostheses”. Data collection was performed by a single examiner in the evaluation periods of 1, 6, 12, 24, 36 and 48 months. For the impact on quality of life, a modified OIDP (Oral Impact of Daily Performance) was used. An analysis of clinical longevity was performed using Ryge's modified criteria with a clinical mirror and explorer. The data on the survival of laminates of different materials were plotted using the Kaplan-Meier curve. The Ryge criteria scores and impact on the patient's quality of life were descriptively arranged. The thicknesses for cervical, medial and incisal were compared between the different materials using the ANOVA One-Way test. For statistical analysis, the level of significance was set at 5%. Results: The clinical survival rate was 100% for the laminates of both materials. Only the discoloration marginally criterion obtained from a classification other than A. The B score was presented by 9 laminates of lithium disilicate and 2 of ultra-translucent zirconia. There was no negative interference from treatment on the quality of life. Talking and relaxing were activities in which the treatment least interfered. No statistically significant difference for laminate thickness between the two materials. Conclusion: The treatment with laminates made of ultratranslucent zirconia has clinical performance similar to the cases treated with lithium disilicate.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Objetivo: avaliar por meio de um ensaio clínico controlado, randomizado e duplo-cego, o desempenho clínico de coroas monolíticas unitárias posteriores confeccionadas em cerâmica infiltrada por polímero, bem como o impacto da reabilitação na satisfação estética e qualidade de vida dos pacientes. Materiais e Métodos: Um total de 20 pacientes que receberam 36 coroas foram incluídos neste estudo. Todos os pacientes assinaram o termo de consentimento livre e esclarecido (TCLE). Os dentes sob reabilitação foram alocados por meio de um sorteio simples entre os grupos: Grupo Controle: (LD- dissilicato de lítio) e grupo Experimental (PIC -Vita Enamic/Vita Zahnfabrik). Registros fotográficos, radiográficos e informações clínicas foram coletados antes, durante e após a reabilitação. As coroas foram avaliadas quanto à taxa de sobrevida clínica (Critérios de USPSH modificados), satisfação estética (escala visual analógica- EVA), qualidade de vida (Oral Impacts on Daily Performances -OIDP), e tipo de falhas (biológicas e técnicas). A coleta de dados foi realizada por um único examinador calibrado e cego para o tipo de material, nos tempos de seguimento T0 (antes do início do tratamento), T1 (1 mês), T2 (6 meses) e T3 (12 meses). O OIDP e os critérios de USPHS foram analisados descritivamente. A satisfação estética foi analisada com MannWhitney/Teste de Friedman/ pós-testes de Wilcoxon. A análise de sobrevivência foi feita usando Kaplan-Meier seguido do teste de log-rank. O nível de significância foi estabelecido em (5%). Resultados: 36 coroas foram colocadas em 20 pacientes com uma média de idade de 47.17 anos (±13,91), sendo 22 (56,4%) coroas do grupo controle (LD) e 14 (35,9%) para o grupo experimental (PIC). A análise de Kaplan-Meier revelou uma taxa de sobrevida de 83,5% para PIC e de 86,2% para LD sem diferenças significativas entre eles (P>0.05). Quatro falhas foram registradas, 2 em cada grupo, sendo dois descolamentos, uma de PIC após 1 mês e uma de LD após 6meses. Houve também uma fratura do dente (LD) e mobilidade grau III (PIC) após 12 meses de acompanhamento. Não houve diferença significativa na satisfação estética, entre o grupo controle e grupo experimental (Mann-Whitney - P>0.05). A satisfação estética foi significativamente maior após 1(T1), 6(T2) e 12(T3) meses quando comparado ao baseline (T0) (Teste de Friedman - P0.05). Four failures were recorded, 2 in each group, two detachments after 1(PIC) and 6 months (LD), a tooth fracture (LD), and grade III mobility after (PIC) 12 months of follow-up. There was no significant difference in aesthetic satisfaction between the control group and the experimental group (Mann-Whitney, P>0.05). Aesthetic satisfaction was significantly higher after 1 (T1), 6 (T2), and 12 (T3) months when compared to baseline (T0) (Friedman test - P

Preparo de canal radicular ,CIENCIAS DA SAUDE::ODONTOLOGIA [CNPQ] ,ProTaper gold ,ProDesign logic ,Endodontia ,Microtomografia computadorizada - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Esta pesquisa objetivou avaliar as alterações morfológicas resultantes da instrumentação de 20 raízes mesias de molares humanos inferiores consideradas severamente curvas, e comparar os sistemas ProTaper Gold (PTG) e ProDesign Logic (PDL), através da análise do transporte apical e da capacidade de centralização, além do tempo necessário para preparo do canal radicular. A amostra foi constituída por vinte raízes mesiais de molares inferiores pareadas anatomicamente com base em dimensões morfológicas semelhantes usando avaliação por microtomografia computadorizada (micro-CT) (resolução = 19 µm) atribuídas a dois grupos experimentais (n = 10) de acordo com o sistema usado para a preparação do canal radicular: Grupo 1 – PTG e Grupo 2 – PDL. Em seguida, os espécimes foram novamente digitalizados e as imagens correspondentes dos canais mesias, pré e pós-instrumentação, foram examinadas em três níveis de secção transversal (3, 5 e 7 mm da extremidade apical da raiz) para analisar o transporte e a centralização do canal. Aplicou-se o teste estatístico de ANOVA, apresentando distribuição normal em relação ao transporte apical, não observando diferença estatística entre os grupos (p > 0,05). Para análise da capacidade de centralização foi observado distribuição não normal, e aplicou-se o teste Mann-Whitney, onde foi observado diferença estatística entre os grupos no nível de 5mm (p = 0,0410) onde PTG apresentou menor capacidade de centralização quando comparado ao grupo PDL. Não houve correlação entre as variáveis em questão. Em relação ao tempo efetivo para instrumentação, a análise demonstrou que houve diferença estatisticamente significativa entre os grupos (p < 0,0001), sendo realizado um pós-teste t de amostras relacionadas confirmando a diferença estatística (72.200; t = 9.3203; p < 0.001), sendo PDL mais rápido para alcançar o comprimento de trabalho (CT) do que o grupo PTG. Todos os procedimentos estatísticos foram realizados com nível de significância de 5%. Portanto, PTG e PDL tiveram resultados semelhantes em relação a ausência de transporte do canal, já PDL apresentou maior capacidade de centralização quando se refere ao nível de 5mm e se mostrou mais rápido que PTG por ter sido necessário um tempo menor de instrumentação. Ademais, todos os sistemas se apresentaram seguros para o uso clínico uma vez seguindo as recomendações dos fabricantes. This research aimed to evaluate the morphological changes resulting from the instrumentation of 20 mesial roots of severely curved lower human molars, and to compare the ProTaper Gold (PTG) and ProDesign Logic (PDL) systems through the analysis of apical canal transportation and centering ability beyond the time required for root canal preparation. The sample consisted of twenty anatomically paired lower molar mesial roots based on similar morphological dimensions using micro-CT evaluation (resolution = 19 µm) assigned to two experimental groups (n = 10) according to the system used for the preparation of root canal: Group 1 - PTG and Group 2 - PDL. The specimens were then digitized again and the corresponding mesial canal images, pre and post-instrumentation, were examined at three cross-sectional levels (3, 5 and 7 mm from the apical root end) to analyze apical canal transportation and centering ability. The ANOVA statistical test was applied, presenting normal distribution in relation to the apical canal transportation, not observing statistical difference between the groups (p> 0.05). For analysis of the centering ability, non-normal distribution was observed, and the Mann-Whitney test was applied, where a statistical difference was observed between the groups at the 5mm level (p = 0.0410) where PTG presented lower centering ability when compared to the PDL group. There was no correlation between the variables in question. Regarding the effective instrumentation time, the analysis showed that there was a statistically significant difference between the groups (p

CIENCIAS DA SAUDE::SAUDE COLETIVA [CNPQ] ,Braquetes ,Esmalte dentário ,Adesividade - Abstract
Objetivo: Avaliar o efeito de diferentes tratamentos de superfície na resistência de união de bráquetes metálicos colados ao esmalte e no grau de conversão dos agentes de colagem, utilizando diferentes protocolos de polimerização. Metodologia: Cento e vinte coroas dentárias de incisivos bovinos foram incluídas em blocos de resina acrílica, lixadas e distribuídas aleatoriamente em 12 grupos. Em seguida, bráquetes metálicos foram colados no esmalte planificado de acordo com os fatores “tratamento de superfície” (A-ácido fosfórico, ATxt-ácido fosfórico+primer Transbond XT®/3M, Tse-Transbond Plus Self Etching Primer®/3M e SBU-Single Bond Universal®/3M) e “polimerização” (R20-Radii-Cal®/20 segundos, V20-Valo Cordless®/20 segundos e V3-Valo Cordless®/3 segundos). As amostras foram armazenadas por 6 meses (água, 370C) e, depois, submetidas ao ensaio de resistência de união cisalhamento (RUC), 300KgF, 1mm/min. Utilizando os mesmos protocolos do ensaio anterior, 120 discos de resina foram confeccionados para análise do grau de conversão (GC). Os dados da RUC (MPa) e do GC (%) foram analisados pelo ANOVA (2 fatores) e Teste de Tukey (5%). As falhas foram classificadas de acordo com o Índice Remanescente Adesivo (IRA) e avaliadas através dos testes Kruskal-Wallis e Mann-Whitney (5%). Resultados: Para a RUC, os fatores “polimerização” (R20=8,146B ; V20=13,271A ; V3=5,26C , p=0.0001) e “tratamento de superfície” (A=3,18C ; ATxt=13,63A ; Tse=12,38A ; SBU=6,37B , p=0.0001) mostraram-se estatisticamente significantes. Os maiores valores de adesão foram encontrados para o grupo ATxtV20 (22,298A ) e os menores, para o grupo AR20 (1,27E ). Quanto ao IRA, o escore 2 foi o mais prevalente nos grupos A, ATxt, V20 e V3, enquanto que o escore 4 foi o mais prevalente nos grupos Tse, SBU e R20, sem diferença significante entre eles (p=1,0). No que diz respeito ao GC, os fatores “polimerização” (R20=66,67A ; V20=58,48B ; V3=45,12C , p=0.0001) e “tratamento de superfície” (A=52,01B , ATxt=59,71A , Tse=51,47B , SBU=63,84A , p=0.0001) mostraram-se estatisticamente significantes. Conclusões: O Tse mostrou-se mais sensível às variações nos protocolos de polimerização do que os outros tratamentos de superfície. Já o tratamento A não apresentou valores de RUC e GC adequados para a colagem de bráquetes metálicos ao esmalte. Objective: To evaluate the effect of different surface treatments and polymerization protocols on the bond strength of brackets to enamel, and the degree of conversion of the bonding agents. Methods: 120 bovine crowns were embedded in acrylic resin blocks and sanded. Next, the blocks were randomly assigned into 12 groups. Metal brackets were bonded to enamel according to the "surface treatment" factor (A: Phosphoric Acid; ATxt: Phosphoric Acid + Transbond XT Primer®; Tse: Transbond Plus Self Etching Primer®; and SBU: Scotchbond Universal®) and "polymerization" factor (R20: Radii-Cal®/20 seconds; V20: Valo Cordless®/20 seconds; and V3: Valo Cordless®/3 seconds). All samples were stored for 6 months (water, 37ºC) and then subjected to a shear bond strength test (SBS). Using the same factors, 120 resin discs were made to assess the degree of conversion (DC) of the monomer. Data from the SBS (MPa) and DC (%) were analyzed by analysis of variance (2 factors) and Tukey's test (5%). Bond failures were classified according to the Adhesive Remnant Index (ARI) and analyzed with the Kruskal-Wallis and Mann-Whitney tests (5%). Results: For the SBS, the factors "polymerization" (R20=8.1B ; V20=13.2A ; V3=5.2C , p=0.0001) and “surface treatment” (A=3.1C ; ATxt=13.6A ; Tse=12.3A ; SBU=6.3B , p=0.0001) were statistically significant among groups. The highest adhesion value were found for the ATxtV20 group (22.2A ) and the lowest value for the A/R20 group (1.2E ). Regarding ARI, score 2 was the most prevalent in groups A, ATxt, V20 and V3, while score 4 was the most prevalent in the Tse, SBU and R20 groups, with no significant difference between them (p=1.0). Regarding DC, the factors "polymerization" (R20=66.6A ; V20=58.4B ; V3=45.1C , p=0.0001) and "surface treatment" (A=52B , ATxt=59.7A , Tse=51.4B , SBU=63.8A , p=0.0001) were statistically significant. Conclusions: Tse was more sensitive to the variations in polymerization protocols than the other surface treatments. Treatment A did not present suitable bond strength or degree of conversion.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Aim: To determine the frequency and type of complications related to removable partial denture (RPD) less, Kennedy Class I, over time . Materials and Methods: This observational study consisted of a sample of 65 users PPR lower arches in Kennedy Class I and dentures, rehabilitated in the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). Patients were followed through periodic controls during periods of 60 days, 6 months and 1 year from installation. After the first year of control had other returns annually. The occurrence of complications or prosthetic failure was observed and recorded in a specific clinical record over 39 months. The patterns of failures observed were classified in the following situations: occurrence of traumatic ulcers after 2 months of installation, lack of retention, fracture or caries in the rest, fracture or dislocation of the artificial teeth, the larger connector fracture, fracture clip fracture support, poor support (need to reline the denture) and prosthesis fracture. Results: The incidence of complications was low frequency, being higher in the second year of use of the prosthesis. Among the complications that occurred more is the loss of retention (31.57%). Failures more severe and difficult to solve as the fracture elements of the metal structure of the PPR had low occurrence and were represented by only one case of the larger connector (5.3%) fractures. Conclusion: Removable partial dentures mandibular free end opposing of the conventional dentures have a low complication rate after 39 months of use when subjected to periodic controls Objetivo: Verificar a frequência e tipo de complicações relacionadas à prótese parcial removível (PPR) inferior, classe I de Kennedy, ao longo do tempo. Materiais e Métodos: Este estudo observacional foi composto por uma amostra de 65 usuários de PPR inferior em arcos Classe I de Kennedy e prótese total superior, reabilitados no Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN). Os pacientes foram acompanhados por meio de controles periódicos nos períodos de 60 dias, 6 meses e 1 ano desde a instalação. Após o primeiro ano de controle os demais retornos tiveram periodicidade anual. A ocorrência de complicações ou falhas protéticas foi observada e registrada em ficha clínica específica ao longo de 39 meses. Os padrões de falhas observados foram enquadrados nas seguintes situações: ocorrência de úlceras traumáticas depois de 2 meses de instalação, ausência de retenção, fratura de nicho ou cárie sob o nicho, fratura ou descolamento dos dentes artificiais, fratura do conector maior, fratura de grampo, fratura do apoio, suporte deficiente (necessidade de reembasamento da prótese) e fratura da prótese. Resultados: A ocorrência de complicações apresentou baixa frequência, sendo maior a partir do segundo ano de uso da prótese. Dentre as complicações que mais aconteceram está a perda de retenção (31,57%). Falhas de maior gravidade e de difícil resolução como a fratura de elementos da estrutura metálica da PPR tiveram baixa ocorrência e foram representadas por apenas um caso de fratura do conector maior (5,3%). Conclusão: Próteses parciais removíveis de extremidade livre mandibulares opostas a próteses totais convencionais apresentam baixo índice de complicações após 39 meses de uso quando submetidas a controles periódicos

CIENCIAS DA SAUDE [CNPQ] ,Disfunção temporomandibular (DTM). Diagnóstico de DTM. Questionário simplificado. Validação. Padrão ouro. RDC/TMD - Abstract
As disfunções temporomandibulares (DTM) representam a maior causa de dor não dentária da região orofacial. Dada sua alta prevalência na população em geral e a existência de inúmeros instrumentos diagnósticos não padronizados, buscou-se elaborar e validar um questionário simples, de acessibilidade ampla e aplicação prática, com vistas a contribuir para o diagnóstico e o estudo epidemiológico das mesmas. A estratégia utilizada na montagem do instrumento foi estabelecida com base na avaliação criteriosa de questionários já existentes na literatura, validação de expertos na área de DTM, validação fatorial, de face (na primeira fase do estudo) e, frente ao padrão ouro (RDC/TMD), na segunda fase do estudo. Na primeira fase, participaram 160 indivíduos. A consistência interna resultou num Coeficiente Alfa de Cronbach de 0,752 para o questionário com sete itens; enquanto que para o questionário com cinco itens, este resultado foi de 0,694, não sendo o mesmo, considerado baixo por avaliar apenas cinco questões e ainda, em razão do tema central da pesquisa ser bastante subjetivo. A análise fatorial confirmatória apontou para uma variância total dos fatores extraídos do questionário com sete itens, de 58,2 % e do questionário com cinco itens de 70,04%. Portanto, o questionário com cinco questões, apresentou resultados estatísticos superiores ao de sete questões. Na validação frente ao padrão ouro (RDC/TMD), foram avaliados 99 indivíduos tendo sido testados os dois questionários, com sete e com cinco questões. Na estrutura com sete questões, ao se categorizar as mesmas por totais de pontos obtidos, em quatro condições, obteve-se o melhor resultado quando se considerou com DTM a faixa entre 10 e 21 pontos, sendo 85,1% positivos também no RDC/TMD, com acurácia de 90,1% e Kappa 0,817. Nesta condição, a sensibilidade encontrada foi de 95% (IC 95%, 91 a 99), especificidade de 87% (IC 95%, 81 a 93), VPP 85%, VPN 96%, LR+ 7,3 e LR- 17,4. Quando os dados foram avaliados para o questionário com cinco questões (QST/DTM), pode-se observar que o melhor ponto de corte foi quando se considerou como portadores de DTM, os indivíduos na faixa entre 7 e 15 pontos, com acurácia de 85,8% e Kappa 0,817. Nesta condição, a sensibilidade foi 88% (IC 95%, 81,6 a 94,4), especificidade 84% (IC 95%, 76,8 a 91,2), VPP 80%, VPN 90,5%, LR+ 5,5 e LR- 7,0. A simplicidade do presente questionário (QST/DTM) com apenas cinco questões, possibilita seu uso como elemento de triagem inicial na área da dor orofacial em disfunção temporomandibular, com boa compreensibilidade, confiabilidade, reprodutibilidade e possibilidade de aplicação em pesquisas epidemiológicas. Concluiu-se que o questionário aqui validado, permite sua aplicação de forma simples tanto por profissionais e pesquisadores da Odontologia como de outras áreas da saúde

CIENCIAS DA SAUDE::SAUDE COLETIVA [CNPQ] ,Aconselhamento. Desordem Temporomandibular. Dor Orofacial ,Counseling. Temporomandibular Disorders. Orofacial Pain - Abstract
The aim of this controlled trial was to evaluate the effectiveness of counseling in pain, function and well-fare outcomes on the management of patients with temporomandibular disorder (TMD). Therefore, 51 consecutive patients were allocated to one of the research groups. In Group I, was instituted counseling therapy for Group II was conducted treatment as usual with occlusal splint. Patients were followed for returns at 7, 15, 30 and 60 days after baseline. At baseline, all patients were examined and assessed RDC/TMD form, which was administered by a single trained and calibrated examiner, in addition, the patients were referred for specific treatment according to the group to which belonged. The clinical and functional impairment was assessed at each visit through the Temporomandibular Index (TMI). In each session, the patients were also surveyed about pain intensity using a Visual Analogue Scale (VAS). To analyze the impact of pain on quality of life, OHIP-14 questionnaire was used. The results showed 26 patients in Group I with a mean age of 35.15 ± 10.79 years. 25 patients were allocated to Group II. The mean age was 27.36 ± 10.34 years. The counseling was effective in reducing the intensity of pain (VAS), with significant improvement observed at 7 day follow-up (p 0.05) nor in the short term (7 days) neither in long term (60 days). It was concluded therefore that, for the studied sample, counseling consisted in an effective treatment option for the control of signs and symptoms of TMD, with results in the short and long term similar to the usual treatment group. O objetivo do presente ensaio clínico controlado foi avaliar a eficácia do aconselhamento sobre a dor, função e qualidade de vida, no tratamento a pacientes com Disfunção Temporomandibular (DTM). Para tanto, 51 pacientes consecutivos foram alocados para um dos grupos da pesquisa. Para o Grupo I, foi instituída terapia com aconselhamento e para o Grupo II, foi realizado tratamento convencional por meio de dispositivos oclusais. Os pacientes foram acompanhados em retornos de 7, 15, 30 e 60 dias após o baseline. No baseline, todos os pacientes foram examinados e diagnosticados como portadores de DTM através do índice RDC/TMD, que foi aplicado por um único examinador treinado e calibrado, além disso, os pacientes foram encaminhados para o tratamento específico de acordo com o grupo ao qual pertenciam. O grau de comprometimento clínico e funcional foi avaliado em cada uma das visitas por meio do Índice Temporomandibular (TMI). Em cada sessão, os pacientes foram ainda inquiridos a respeito do nível de dor por meio de uma Escala Visual Analógica (EVA). Para a análise do impacto da dor na qualidade de vida, foi utilizado o questionário OHIP-14. Os resultados apresentaram 26 pacientes do Grupo I com idade média de 35,15 ± 10,79 anos. No Grupo II foram tratados 25 pacientes, com faixa etária média de 27,36 ± 10,34 anos. O aconselhamento foi eficaz na redução da intensidade de dor (EVA), com melhora significativa observada já com 7 dias de acompanhamento (p0,05) nas avaliações. Pôde-se concluir, portanto que, para a amostra estudada, o aconselhamento constituiu-se em uma opção de tratamento eficaz para o controle de sinais e sintomas da DTM, com resultados similares aos do grupo tratado por meio de dispositivos oclusais

The epidemiology of temporomandibular disorders varies widely in the literature. The aim of this study was to determine the prevalence of TMD in dental students of the Federal University of Rio Grande do Norte assessed by different indexes. The sample consisted of 101 individuals selected by a randomized process, whose general outline was systematic sampling. For evaluation of the signs and symptoms of TMD, an anamnestic index, Fonseca s protocol, and two clinical indexes, the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders), or standard index, and the Helkimo s Clinical Dysfunction Index were applied. Data were analyzed using the chi-square test and kappa, besides verifying the sensitivity and specificity (5% significance). The diagnosis of TMD by different indexes showed a variation in the prevalence between 72.3% (Helkimo s Clinical index), 64.4% (Fonseca s anamnestic index) and 35.6% (RDC/TMD). There was no statistical difference between the sexes for the RDC/TMD, although this difference was found for Fonseca s and Helkimo s indexes (p

The evaluation criteria of the cases treated with dental implants are based on clinical and radiographic tests. In this context it is important to conduct research to determine prognosis of different types of prosthetic rehabilitation and determination of the main problems affecting this type of treatment. Thus, the objective of this study was to assess the prosthetic conditions of individuals rehabilitated with implant-supported prosthesis. In this cross-sectional study 153 patients were treated, accounting for a sample of 509 implants. The failures were observed by clinical and radiographic examination. The results showed that the fracture (0.2%) loss (0.4%) and loosening of the screws (3.3%) were failures are less frequent. The fracture structures as the resin (12.4%), porcelain (5.5%) and metallic (1.5%), loss of resin that covers the screw (23.8%) and loss of retention overdentures on implants (18.6%) had a higher occurrence. The failure of adaptation between the abutment and the implant (6.9%) and especially between the prosthesis and the abutment (25.4%) had a high prevalence and, when related to other parameters showed a significant association, particularly with the cemented prosthesis (OR = 6.79). It can be concluded that to minimize the appearance of failures, protocols must be observed from diagnosis to the settlement and control of prostheses on implants, particularly with respect to technical steps of the making of the prosthesis and care in radiographic evaluating the fit between their components Os critérios de avaliação dos casos tratados com implantes osseointegrados são baseados em testes clínicos e exames radiográficos. Nesse contexto, é importante a realização de pesquisas na determinação do prognóstico dos diferentes tipos de reabilitações protéticas e na determinação dos principais problemas que atingem este tipo de tratamento. Desta forma, o objetivo deste trabalho foi avaliar as condições protéticas de indivíduos reabilitados com implantes osseointegrados e próteses sobre implantes. Neste estudo transversal foram atendidos 153 pacientes, contabilizando uma amostra de 509 implantes. As falhas foram observadas através do exame clínico e radiográfico. Os resultados demonstraram que a fratura (0,2%), a perda (0,4%) e o afrouxamento dos parafusos (3,3%) foram as falhas menos frequentes. A fratura das estruturas como a resina (12,4%), porcelana (5,5%) e metálica (1,5%), a perda da resina que recobre o parafuso de fixação (23,8%) e a perda de retenção nas próteses overdentures (18,6%), tiveram uma ocorrência maior. A falha de adaptação, entre o pilar e o implante (6,9%) e principalmente entre a prótese e o pilar (25,4%) teve uma alta prevalência e, quando relacionada com outros parâmetros, demonstrou uma associação significativa, principalmente com a fixação do tipo cimentada (OR= 5,39). Pode-se concluir que para minimizar o aparecimento de falhas, protocolos devem ser observados desde o diagnóstico até o assentamento e controle das próteses sobre implantes, principalmente com relação aos passos técnicos da confecção da prótese e com o cuidado em avaliar radiograficamente a adaptação entre seus componentes

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior There is a lack of clinical studies evaluating techniques of functional impression for partially edentulous arches. The aim of this double-blind non-randomized controlled clinical trial was to compare the efficacy of altered cast impression (ACI) and direct functional impression (DFI) techniques. The efficacy was evaluated regarding the number of occlusal units on denture teeth, mucosa integrity at 24-hour follow-up and denture base extension. The sample included 51 patients (female and male) with mean age of 58.96 years treated at Dental Department of UFRN. The patients, exhibiting edentulous maxilla and mandibular Kennedy class I, were divided into two groups (group ACI, n=29; group DFI, n=22). Clinical evaluation was based on the number of occlusal units on natural and/or artificial teeth, mucosa integrity at 24-hour follow-up, and denture base extension. Statistical analysis was conducted using the software SPSS 17.0® (SPSS Inc., Chicago, Illinois). Student T-test was used to reveal association between number of occlusal units and impression technique while chi-square test showed association between mucosa integrity and impression technique. Fischer s exact test was applied for association between denture base extension and impression technique at 95% level of significance. No significant difference was observed between the groups regarding number of occlusal units, mucosa integrity and denture base extension. The altered cast technique did not provide significant improvement in comparison to the direct technique when the number of occlusal units, mucosa integrity and denture base extension A literatura científica é carente de estudos clínicos que avaliem a eficiência de técnicas de moldagem funcional para arcos parcialmente desdentados. Objetivou-se realizar um ensaio clínico controlado, não randomizado e duplo-cego, para comparar a eficiência da técnica de moldagem funcional do modelo alterado (TMMA) com a técnica de moldagem funcional direta (TMD), em relação ao número de pontos de contato oclusais por unidade oclusal na instalação de novas próteses, a integridade da fibromucosa na sessão de controle de 24 horas e a extensão da base de prótese. A amostra foi constituída por 51 pacientes, com média de idade de 58,96 anos, portadores de arco maxilar totalmente desdentado e Classe I de Kennedy mandibular, de ambos os sexos, reabilitados nas clínicas do Departamento de Odontologia da Universidade Federal do Rio Grande do Norte. Os pacientes foram divididos em dois grupos: grupo TMMA (n=29) e Grupo TMD (n=22). As seguintes variáveis foram utilizadas para as medidas clínicas: número de pontos de contato oclusais por unidade oclusal, a integridade da fibromucosa no retorno programado de 24 horas e a extensão da base da prótese. Para análise estatística, utilizou-se o programa SPSS 17.0® (SPSS Inc., Chicago, Illinois) e aplicou-se o teste t de Student para verificar a associação do número de pontos de contato oclusais por unidade oclusal em dentes naturais e artificiais e a técnica de moldagem. Para verificar a associação entre a integridade da fibromucosa e a técnica, foi utilizado o teste quiquadrado. O teste exato de Fisher foi usado para verificar a associação entre a extensão da base da prótese e a técnica, com confiança estatística de 95%. Não existiu diferença estatisticamente significativa entre os dois grupos quanto à técnica de moldagem em relação ao número de pontos de contato oclusais, à integridade da fibromucosa e à extensão da base da prótese. A técnica de moldagem funcional do modelo alterado não oferece vantagens significativas, quando comparada à técnica direta, em relação à quantidade de número de pontos de contato oclusais por unidade oclusal, à integridade da fibromucosa e à extensão da base da prótese

Some studies reported in the literature that emotional factors and quality of life may be involved both in aetiology, as in the progression of Temporomandibular disorders (TMD). Proposition: The purpose of this study is to observe a possible association between different forms of anxiety, quality of life and general health of patients diagnosed as carriers of various types and levels of Temporomandibular Dysfunction. Methodology: The sample consisted of 60 patients diagnosed as carriers of TMJD origin of muscle, joint, or both, with different levels of severity (mild TMD, moderate and severe). The patients were diagnosed with TMD-RDC (Research Diagnostic Criteria) to assess the type of dysfunction (muscle or joint) and by the Protocol of Fonseca to verify the degree of dysfunction (mild, moderate or severe). To evaluate the psychosocial aspects were used three self-applied, with the purpose of obtaining information about the general health (General Health Questionnaire - GHQ), the type of anxiety (Trait Anxiety Inventory-State - STAI) and quality of life (World Health Organization Quality Of Life Short WHOQOL-brief). Results: There was a correlation between all indicators studied in several forms of TMD with varying degrees of commitment. Quality of life appeared linked to the type and the level of TMD: Muscular and Articular TMD (p = 0,037), Disk Displacement With Reduction (p = 0.01) and Mild TMD (p = 0.042). The General Health showed association with the level of TMD, with the exception of the stress factor (p = 0.78). For the analysis of the types and levels to Severe Muscular TMD had a statistically significant indicator of the quality of life (p = 0049). The anxiety only showed association with the level of TMD (p = 0,047 for anxiety-trait). Conclusion: Besides the limitations of the study, it was concluded that anxiety, quality of life and general health are important psychosocial indicators, which are linked to several forms of TMD in different levels of severity Alguns estudos na literatura relatam que os fatores emocionais e a qualidade de vida podem estar envolvidos tanto na etiologia, quanto na progressão das Disfunções Temporomandibulares (DTM). Proposição: O objetivo do presente estudo é o de observar uma possível associação entre as diferentes formas de ansiedade, a qualidade de vida e a saúde geral em pacientes diagnosticados como portadores de diferentes tipos e graus de Disfunção Temporomandibular. Metodologia: A amostra foi constituída por 60 pacientes diagnosticados como portadores de Disfunção Temporomandibular de origem muscular, articular ou ambas, com diferentes graus de severidade (DTM leve, moderada e severa). Os pacientes foram diagnosticados através do RDC-TMD (Research Diagnostic Criteria) para avaliar o tipo de disfunção (muscular ou articular) e através do Protocolo de Fonseca para verificar o grau da disfunção (leve, moderada ou severa). Para avaliação dos aspectos psicossociais foram utilizados três questionários auto-aplicáveis, com o objetivo de obter informações a respeito da saúde geral (Questionário de Saúde Geral QSG), do tipo de ansiedade (Inventário de Ansiedade Traço-Estado - IDATE) e da qualidade de vida (World Health Organization Quality Of Life abreviado -WHOQOL brief). Resultados: Observou-se associação entre todos os indicadores pesquisados nas mais diversas formas de DTM com variados graus de comprometimento. A Qualidade de vida apareceu associada ao Tipo e ao Grau de DTM: DTM Muscular e Articular (p=0,037), Deslocamento de Disco Com Redução (p=0,01), e DTM Leve (p=0,042). A Saúde Geral apresentou associação com o Grau de DTM, à exceção do fator estresse (p=0,78). Em relação à análise conjunta dos tipos e graus, a DTM Muscular Severa teve associação estatisticamente significante para o indicador de Qualidade de Vida (p=0,049). A Ansiedade apresentou associação apenas com o Grau de DTM (p=0,047 para ansiedade-traço). Conclusão: Dentro das limitações do estudo, pode-se concluir que a ansiedade, a qualidade de vida e a saúde geral são importantes indicadores psicossociais, que estão associados às mais diversas formas de DTM, em diferentes graus de severidade

- Abstract
Purpose: To identify the prevalence of and factors associated with total edentulism in the older Brazilian population and to verify whether edentulism influences self-perception of oral health and difficulty in eating., Materials and Methods: This cross-sectional, population-based study used the database of the National Health Survey conducted in Brazil. Chi-square test was initially used for data analysis. Subsequently, a multivariate analysis of Poisson multiple regression type was performed to verify the adjusted prevalence ratios., Results: A total of 43,554 older adults participated in the study, of whom 32% had completely lost their teeth. This total edentulism, based on the multivariate analysis, was associated with female gender, advanced age, illiteracy, smoking, and lack of health insurance or dental insurance (P < .001 for all). Total edentulism had an impact on better self-perception of oral health (P < .001) and greater difficulties in eating (P = .001)., Conclusions: Total edentulism in older adults is associated with worse socioeconomic conditions and a worse lifestyle. This condition has a negative impact on diet and positively affects self-perception of oral health.

- Abstract
Statement of Problem: While rehabilitation with implant-supported crowns in the posterior region is widely practiced, guidance on clinical considerations when choosing between splinted or nonsplinted implant-supported crowns is limited., Purpose: The purpose of this systematic review with meta-analysis was to assess whether adjacent implants with internal connections in the posterior region should be treated with splinted or nonsplinted crowns., Material and Methods: The systematic review was registered on the prospective register of systematic reviews (PROSPERO) under the code, CRD42021248525. Two authors searched 4 electronic databases (PubMed, Cochrane Library, Scopus, and Web of Science) independently for articles published up to December 2023. Additionally, a hand search was conducted in the nonpeer-reviewed literature and the reference lists of included articles. Only clinical studies comparing splinted and nonsplinted hexagonal or conical internal connection adjacent implants in the posterior region were considered. A single-arm meta-analysis was conducted using RevMan. Risk of bias and quality were assessed using the Cochrane Collaboration's Tool for Assessing Risk and the Newcastle-Ottawa scale., Results: Qualitative synthesis included 17 studies, and quantitative synthesis involved 13 studies. A total of 2085 implants (1244 splinted and 841 nonsplinted) were inserted in 1027 participants, with observation times ranging from 5 months to 16 years. Thirteen studies related the type of crown retention (cemented or screw-retained). Only 2 studies related annual bone loss results considering the type of crown retention, but whether they were splinted or nonsplinted crowns and significant differences were not specified. The meta-analysis revealed no statistical differences between splinted and nonsplinted implants for biological complications (P=.95, I
2 =0%). However, the nonsplinted implants exhibited significantly more mechanical complications than the splinted implants (P<.001, I2 =1%, RR 0.37; 95% IC [0.26-0.54]). The studies included demonstrated a low risk of bias and were of good quality., Conclusions: Splinting was not found to affect the incidence of biological complications in posterior adjacent implants. However, more mechanical complications occurred in nonsplinted crowns than splinted ones., (Copyright © 2024 Editorial Council for The Journal of Prosthetic Dentistry. Published by Elsevier Inc.

- Abstract
Purpose: To identify the most effective cleaning method for saliva-contaminated zirconia surface before adhesive cementation through a systematic review and meta-analysis., Materials and Methods: PubMed, Scopus, and Web of Science databases were searched to select in vitro studies published through October 2021. Studies that did not perform aging methods, had a sample size less than 5 per group, or did not present a group with zirconia contaminated only with saliva were excluded. Data were extracted and risk of bias was assessed. Statistical analysis comparing the cleaning methods was conducted, and the standardized mean difference was assessed using the R software program., Results: Among 804 potentially eligible studies, 36 were selected for full-text reading, of which 13 were included in qualitative analysis, and 11 of these were subsequently included in the quantitative analysis. A meta-analysis revealed a significant difference in the bond strength between the cleaning methods. Sandblasting with Al2O3 showed a higher bond strength than cleaning solution (Ivoclean, Ivoclar Vivadent) (p < 0.01, I2 = 65%), and both methods promoted higher resin-bond strength to zirconia than water cleaning. In addition, there was no significant difference in the bond strength between alcohol (p = 0.35, I2 = 79%), phosphoric acid (p < 0.23, I2 = 90%), and water cleaning., Conclusion: Sandblasting with Al2O3 seems to be the best method for zirconia surface cleaning before adhesive luting, promoting better resin-bond strength to zirconia.

- Abstract
Objectives: The objective of this review was to assess the literature for evidence investigating the role of TGF-β in temporomandibular joint disease with osteoarthritis., Method: An electronic and manual search was carried out on the databases, MEDLINE/PubMed, Cochrane Library, Web Of Science, and EMBASE, from 1975 to December 2015 by two independent evaluators to identify clinical and laboratory trials in English., Results: The search produced 693 records. Following a process of selection based on certain criteria, eight articles were included., Discussion: This systematic review suggests that TGF-β administration alone does not result in joint regeneration; other factors may be involved, such as TGF-β receptor expression ,and TGF-β receptor mutations that do not allow a correct transduction, resulting in TGF-β deficiency. The anabolism induced by this growth factor is also able to neutralize the catabolic processes that are elevated in osteoarthritis. Therefore, further studies are essential to determine how the concentration of TGF-β in the temporomandibular joints acts as a potential marker for the development of degenerative conditions.
