Monitoring of the Training Load and Well-Being of Elite Rhythmic Gymnastics Athletes in 25 Weeks: A Comparison between Starters and Reserves.

The objective of this study was to monitor the training loads (TL) and well-being of elite rhythmic gymnastics (RG) athletes, as well as compare these variables between starters and reserve gymnasts during 25 weeks of training. Ten athletes from the Brazilian national RG team (17.4 ± 1.1 y of age) were monitored during the general preparatory period (GPP), specific preparatory period (SPP), and pre-competitive period (PCP). The internal TL was quantified with the use of sessional ratings of perceived exertion (sRPE). We assessed well-being daily with a well-being scale. The TL, duration, monotony, and strain were calculated weekly. We found that the internal TL and session durations were 9242 ± 2511 AU and 2014 ± 450 min, respectively. The internal TL, strain, and monotony were greater in the PCP than in the GPP and SPP for starters. In the SPP, there were statistical differences in internal TL (p = 0.036) and strain (p = 0.027) between starters and reserves. In the PCP, there were also statistical differences between starters vs. reserves athletes regarding internal TL (p = 0.027) and strain (p = 0.05). There was no statistically significant difference in well-being between the periods assessed. In conclusion, RG athletes display a higher TL magnitude during the PCP, whereas only reporting non-significant minor variations in well-being. In addition, there is a discrepancy in the TL between starters and reserves.

Association of sleep quality and psychological aspects with reports of bruxism and TMD in Brazilian dentists during the COVID-19 pandemic.

BACKGROUND: Dentists are exposed to contamination by SARS-CoV-2 due to dental interventions, leading to a state of alert and potential risk of negative impact in mental health and sleep quality, associated with Temporomandibular Disorder (TMD) and bruxism. OBJECTIVE: to evaluate the psychosocial status, sleep quality, symptoms of TMD, and bruxism in Brazilian dentists (DSs) during the COVID-19 pandemic. METHODOLOGY: The sample (n=641 DSs) was divided into three groups (quarantined DSs; DSs in outpatient care; and frontline professionals), which answered an electronic form containing the TMD Pain Screening Questionnaire (Diagnostic Criteria for Temporomandibular Disorders - DC/TMD), the Pittsburgh Sleep Quality Index (PSQI), the Depression, Anxiety and Stress Scale (DASS-21), and the sleep and awake bruxism questionnaire. ANOVA test and Mann Whitney post-test were used, with Bonferroni adjustment (p<0.016) and a 95% confidence level. RESULTS: Probable TMD was found in 24.3% (n=156) of the participants, while possible sleep and awake bruxism were diagnosed in 58% (n=372) and 53.8% (n=345) of them, respectively. Among all variables evaluated, only symptoms of depression were significantly greater in the quarantined DSs group when compared to those who were working at the clinical care (p=0.002). Working DSs were significantly less likely (OR=0.630, p=0.001) to have depressive symptoms. Those who were not worried or less worried about the pandemic were less likely to experience stress (OR=0.360), anxiety (OR=0.255), and poor sleep quality (OR=0.256). Sleep had a strong positive and moderate correlation with psychological factors on frontline workers and DSs in outpatient care, respectively. CONCLUSION: The results suggest confinement may have a more negative impact on the life of DSs than the act of being actively working. The concern about Covid-19 and poor sleep quality was significantly prevalent and may negatively affect the quality of life of DSs. Thus, further research on the topic is needed.

Short-Term Effect of Scalp Acupuncture on Pain, Sleep Disorders, and Quality of Life in Patients with Temporomandibular Disorders: A A Randomized Clinical Trial.

OBJETIVE: To evaluate the effects of Chinese scalp acupuncture in patients diagnosed with temporomandibular disorders (TMD) on pain, sleep, and quality of life (QOL), and compare these results with the results from traditional therapies. METHODS: Sixty patients diagnosed with TMD using the research diagnostic criteria for temporomandibular disorders (RDC/TMD) were allocated into four treatment groups: counseling (C = 15), occlusal splint (OS = 15), scalp acupuncture (SA = 15), and manual therapy (MT = 15). Participants were re-evaluated within 1 month. Three questionnaires were used to access sleep disorders, QOL, and pain: The Pittsburgh Sleep Quality Index (PSQI), World Health Organization Quality of Life (WHOQOL-bref), and the Visual Analogue Scale (VAS), respectively. The data obtained were analyzed using the Statistical Package for the Social Science program (SPSS 22.0). RESULTS: The SA group significantly improved pain (P = .015), as well as the OS (P = .01) and MT groups (P = .014). Only the OS (P = .002) and MT (P = .029) groups improved sleep. MT group significantly improved QOL in terms of the physical domain of the WHOQOL-bref (P = .011) and the OS group in the psychological domain (P = .012). CONCLUSIONS: The scalp acupuncture proved to be another alternative for pain relief in patients with TMD, demonstrating positive results in the short term. However, it was not as effective in improving quality of life and sleep.

Short-term effectiveness of conservative therapies in pain, quality of life, and sleep in patients with temporomandibular disorders: A randomized clinical trial.

Objective: To evaluate, in the short term, the effectiveness of conservative therapies in pain, quality of life, and sleep in TMD patients.Methods: Eighty-nine TMD patients diagnosed by RDC-TMD were distributed in occlusal splints (OS; n= 24), manual therapy (MT; n= 21), counseling (C; n= 19), and OS associated with C (OSC; n= 25) therapy groups. Data collection was performed at baseline and within one month by VAS (pain), PSQI (sleep quality -SQ), WHOQOL-BREF (Quality of life - QL) and OHIP-14 (quality of life related to oral health -QLOH). The Split Plot ANOVA test was used to observe the difference between groups and over time.Results: All therapies were effective over time, improving pain (p< .001), SQ (p=.001), QLOH (p< .001), and QL (p= .006), but not between them.Discussion: The therapies were effective in improving pain, SQ, and quality of life; however, no therapeutic group was superior to the other.

Manual Therapy in the Treatment of Myofascial Pain Related to Temporomandibular Disorders: A Systematic Review.

AIMS: To evaluate the effectiveness of manual therapy in the treatment of myofascial pain related to temporomandibular disorders. METHODS: Randomized clinical trials were searched in the Cochrane Library, MEDLINE, Web of Science, Scopus, LILACS, and SciELO databases using the following keywords: temporomandibular joint disorders; craniomandibular disorders; myofascial pain syndromes; myofascial pain; exercise therapy; myofunctional therapy; physical therapy modalities; clinical trial; prospective studies; and longitudinal studies. Studies using the RDC/TMD and manual therapy for myofascial pain were included. All studies were evaluated using the Cochrane Risk of Bias tool. RESULTS: Five studies were included in the present review. Of 279 total patients, 156 were treated with manual therapy only or manual therapy with counseling. Manual therapy was efficient for pain relief in all studies evaluated; however, manual therapy was not better than counseling or botulinum toxin. CONCLUSION: Manual therapy was better than no treatment in one study and better than counseling in another study; however, manual therapy combined with counseling was not statistically better than counseling alone, and manual therapy alone was not better than botulinum toxin. Manual therapy combined with home therapy was better than home therapy alone in one study. Further studies are required due to the inconclusive data and poor homogeneity found in this review.

Conservative therapies to treat pain and anxiety associated with temporomandibular disorders: a randomized clinical trial.

INTRODUCTION: Temporomandibular dysfunction (TMD) is a condition that affects the stomatognathic system. OBJECTIVE: To determine the effect of treatment with an occlusal splint (OS), manual therapy (MT), counselling (CS) and the combination of an occlusal splint and counselling (OSCS) on pain and anxiety in patients with TMD. MATERIALS AND METHODS: A randomised clinical trial was conducted with 89 patients diagnosed with TMD through RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders) and divided into four groups of treatment: OSCS (n = 25); OS (n = 24); MT (n = 21); and CS (n = 19). Participants were assessed before and after 1 month of therapy for pain, anxiety and TMD diagnosis. Pain was measured by a visual analogue scale. To assess anxiety, Hospital Anxiety and Depression Scale (HADS), Beck Anxiety Inventory (BAI) and the State-Trait Anxiety Inventory (STAI-S and T) were used. The data were analysed using SPSS (Statistical Package for Social Science) 22.0. RESULTS: The four groups obtained a significant reduction (P < 0.001) in the pain after 1 month of treatment. Treatment in all groups promoted a significant reduction in anxiety symptoms 1 month after completion, HADS (P < 0.001), BAI (P < 0.001), STAI-T (P = 0.006). Thus, no group was superior to the other in reducing the studied variables. CONCLUSION: The therapies used were effective in reducing pain and anxiety in patients diagnosed with TMD. However, no treatment was superior to the other in reducing the studied variables.

Relationship between anxiety, quality of life, and sociodemographic characteristics and temporomandibular disorder.

OBJECTIVES: The aim of this study was to evaluate the relationship between anxiety, quality of life (QL), and sociodemographic aspects and temporomandibular disorders (TMDs) and to assess the predisposition to TMDs in patients with low QL and anxiety. STUDY DESIGN: In total, 120 patients (60 TMD/60 non-TMD) were screened to assess QL (World Health Organization Quality of Life Brief Version [WHOQOL]); anxiety (Beck Anxiety Inventory [BAI]; the State-Trait Anxiety Inventory[STAI-S and -T]; the Hospital Anxiety and Depression Scale [HADS]); and TMD (Research Diagnostic Criteria for Temporomandibular Disorders-RDC/TMD). Pearson's χ2 test, the Student t test, odds ratio (OR) analysis, and nonconditional logistic regression analysis were performed. RESULTS: Among patients with TMD, 60% were women (P = .002), 65.1% were single (P = .009), and 71.4% were employed (P = .008). Most of the anxious individuals had TMD, according to HADS, 75% (P < .001); STAI-S, 55.6% (P = .035); STAI-T, 54.9% (P = .011); and BAI, 63.9% (P = .002). WHOQOL showed higher QL for non-TMD participants (P < .001). Sociodemographic data showed an association with TMD: gender (OR = 3.5), professional status (OR = 3.3), and marital status (OR = 2.8). WHOQOL presented higher association strength (OR = 9.2), followed by HADS (OR = 5.0). CONCLUSIONS: A relationship exists between sociodemographic aspects, anxiety, and QL and TMD. Patients with TMD have higher anxiety levels and lower QL, and this can interfere with treatment, reinforcing the need for therapies that consider the various factors of the disorder.

Efeitos de diferentes terapias conservadoras sobre a dor, aspectos psicossociais, relacionados ao sono e à qualidade de vida em indivíduos com disfunção temporomandibular: ensaio clínico randomizado / Effects of different conservative therapies on pain, psychosocial aspects, sleep-related aspects and quality of life in individuals with temporomandibular disorders: randomized clinical trial

A disfunção temporomandibular (DTM) consiste em um conjunto de condições que envolve as articulações temporomandibulares (ATM), os músculos mastigatórios e estruturas associadas. É bastante prevalente no Brasil e no mundo, tem caráter multifatorial e auto limitante, o que proporcionou o desenvolvimento de uma grande variedade de terapias para manejo dos seus principais sinais e sintomas. Esse ensaio clínico randomizado cego avaliou o efeito de terapias conservadoras sobre sintomas físicos, psicológicos, relacionados ao sono e à qualidade de vida em pacientes diagnosticados com DTM e se alterações psicológicas e do sono interferem no controle da dor desses pacientes após as condutas terapêuticas. A amostra foi constituída por 87 indivíduos diagnosticados com DTM pelo Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD) randomicamente alocados entre os grupos de tratamento: dispositivo oclusal (DO), aconselhamento (AC), fisioterapia (FT) e DO associado ao AC. Os sintomas de ansiedade foram diagnosticados pelo Índice de Ansiedade Traço-Estado (IDATE), Escala Hospitalar de Ansiedade e Depressão (HADS) e Inventário de Ansiedade de Beck (BAI). Os sintomas de depressão foram avaliados através do HADS e Inventário de Depressão de Beck (BDI). A qualidade subjetiva do sono, qualidade de vida geral e relacionada á saúde bucal, função e intensidade de dor foram investigadas através do Índice de Qualidade do Sono de Pittsburgh (PSQI), Questionário de Qualidade de Vida da Organização Mundial de Saúde - abreviado (WHOQOL), Impacto da Saúde Bucal na Qualidade de Vida (OHIP 14) e Escala Analógica Visual (EVA) respectivamente. As coletas foram realizadas no baseline, com 1 mês e 3 meses após a conclusão das terapias por um investigador cego e treinado. Utilizou-se o teste SPANOVA para a análise do efeito das terapias ao longo do tempo e entre os grupos e os testes de Friedman e Mann Whitney para avaliar os níveis de dor intra e intergrupos em todos os tempos com um nível de significância de 5 %. Observou-se que nenhuma terapia apresentou diferença estatisticamente significante em relação a outra e que todas apresentaram efeitos significativos na melhoria dos índices avaliados (sintomas de ansiedade IDATE p=0,002 ­ HADS p<0,001 ­ BAI p<0,001, depressão BDI p=0,001, qualidade subjetiva do sono PSQI p=0,005, qualidade de vida geral WHOQOL p=0,029 e relacionada a saúde bucal OHIP p <0,001 e índice de dor p<0,001) ao longo do tempo, exceto para o HADS depressão p=0,106. Verificou-se que todos os pacientes com sintomas alterados reduziram significativamente seus níveis de dor após as terapias (HADS p<0,001; BAI p<0,001; BDI p<0,001; PSQI p=0,010), mas que os pacientes ansiosos (BAI p=0,021) tiveram uma redução estatisticamente significativa maior (delta=2,84) quando comparados aos indivíduos normais (delta=1,10) e igualmente a qualidade do sono (QS) alterada (p=0,006). Conclui-se que todas as terapias conservadoras geraram resultados positivos em relação a sintomas físicos, psicológicos, relacionados ao sono e à qualidade de vida e que não houve elementos para afirmar que os tratamentos não foram iguais. E ainda que a presença de sintomas de ansiedade e depressão e QS ruim apresentaram maiores níveis de dor no baseline, porém esses fatores não influenciaram negativamente na melhora após as terapias conservadoras com DO, AC, FT, DO+AC para DTM e que ansiedade e sono alterado podem até gerar um efeito maior nesta redução (AU).

Temporomandibular Disorder (TMD) consists of a set of conditions that involve the temporomandibular joints (TMJ), masticatory muscles and associated structures. It is very prevalent in Brazil and worldwide, has a multifactorial and self-limiting character, which has allowed the development of a great variety of therapies to manage its main signs and symptoms. This blinded randomized clinical trial evaluated the physical, functional, psychological, sleep-related and quality of life symptoms in patients diagnosed with TMD after different therapies: occlusal splint (OS), counseling (C), manual therapy (TM) and associated OS to C and if psychological and sleep disturbances interfere in the pain control of these patients after the therapeutic conducts. The sample consisted of 87 individuals diagnosed with TMD by the Research Diagnostic Criteria for Temporomandibular Disorders (RDC-TMD) randomly assigned between the treatment groups. Anxiety symptoms were diagnosed by the Trait-State Anxiety Index (IDATE), Hospital Anxiety and Depression Scale (HADS), and Beck Anxiety Inventory (BAI). Symptoms of depression were assessed using the HADS and Beck Depression Inventory (BDI). The subjective quality of sleep, general quality of life and related to oral health, function and intensity of pain were investigated through the Pittsburgh Sleep Quality Index (PSQI), World Health Organization Quality of Life Questionnaire - bref (WHOQOL ), Oral Health Impact Profile (OHIP 14) and Visual Analogue Scale (VAS), respectively. The assessments were performed at the baseline, 1 month and 3 months after completion of the therapies by a blind and trained investigator. The SPANOVA test was used to analyze the effect of therapies over time and between groups with a confidence level of 95% and Friedman and Mann Whitney tests to assess intra- and intergroup pain levels at all times with a significance level of 5%. It was observed that no therapy had a statistically significant difference in relation to the other, and that all had significant effects on the improvement of the indexes evaluated (anxiety IDATE p=0.002 ­ HADS p<0.001 ­ BAI p<0.001 and depression BDI p=0.001 symptoms, subjective sleep quality PSQI p=0.005, general quality of life WHOQOL p=0.029, oral health related quality of life OHIP p <0.001 and pain intensity p<0.001) over time, except for the HADS depression (p = 0.106). It was found that all patients with altered symptoms significantly reduced their pain levels after the therapies (HADS p <0.001; BAI p <0.001; BDI p <0.001; PSQI p = 0.010), but that anxious patients (BAI p = 0.021) had a statistically significant greater reduction (delta = 2.84) when compared to normal individuals (delta = 1.10) and also the altered QS (p = 0.006). It was concluded that all conservative therapies generated positive outcomes regarding physical, psychological, sleep-related and quality of life symptoms and there were no elements to state that the treatments were not equal. And although anxious, depressed patients with low QS had higher levels of pain in the baseline and these factors did not negatively influence their reduction after DO, AC, FT, DO + AC and TMD therapies, and that anxiety and altered sleep may even have a greater effect on this reduction (AU).

Relationship between anxiety and temporomandibular disorders in dental students.

OBJECTIVE: To evaluate the prevalence of temporomandibular disorder (TMD) in dental students and its correlation with anxiety. METHODS: After probability sampling, 105 students were selected. The diagnosis of TMD was carried out using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - Axis I; the anxiety level was obtained by the State-Trait Anxiety Inventory (STAI). Data from TMD and anxiety were calculated through frequency and Chi-square test to assess the association between TMD and anxiety, considering a significance level of 5%. RESULTS: TMD was present in 36.2% of the students; disc displacement (42.1%), and arthralgia (42.1%) were the most prevalent subtypes. The majority of students presented both traits (57.1%) and state (65.7%) anxiety in mild levels, followed by moderate levels. No statistical association between TMD and anxiety was found (p > 0.05). CONCLUSION: Joint TMD was the most prevalent subtype of TMD in dental students and was not associated with anxiety levels.

Resilience, stress and injuries in the context of the Brazilian elite rhythmic gymnastics.

The study had the goal to study the relationship between resilience, stress and injuries in the sport context. Eight female athletes, part of the Rhythmic Gymnastics Brazilian Team along the Olympic Cycle 2015-2016 participated in the study, with a mean age of 20.4±2.5 years. The following instruments were used: RESTQ-76 Sport, CD-RISC 10, documental analysis of physical therapy records, and structured questionnaire. Data was analyzed by descriptive statistics (frequency, mean and standard deviation); Repeated Measured ANOVA with Bonferroni's post-hoc, Student's "t" test, Friedman test, Pearson Correlation Coefficient, Cohen's d, and inductive thematic analysis. We found relatively stable levels of stress and recovery across the season; total recovery levels were higher than stress at all four measured timepoints (p<0.05); All athletes had at least one injury, with a total of 14 injuries; No significant correlations were found between the quantitative scores of resilience, stress and recovery; Training and the sport's scoring system were the most relevant perceived stressors; athletes presented meta-cognition and a non-positive evaluation (neutral) of stressors; Social support was considered the main psychological factor for the resilience process; such process resulted in improved control and interpretation of emotions; Our hypothesized model proposes that, in the relationship between stress and injuries, resilience acts by optimizing the injury recovery process. It was concluded that resilience plays a role in the process of injury rehabilitation and stress control in elite rhythmic gymnastics' athletes.

Sensitivity and specificity of different indexes used to diagnose Temporomandibular Disorders / Sensibilidade e especificidade de diferentes índices utilizados para o diagnóstico de disfunções temporomandibulares

Objective: To verify the level of agreement among different indexes used to achieve the prevalence of Temporomandibular Disorders (TMD). Material and Methods: One hundred one dental students were selected by a randomized process. TMD were evaluated by the Fonseca's Anamnestic Index (FAI), Helkimo's Clinical Index (HCI), and the Research Diagnostic Criteria for TMD (RDC/TMD). Data was analyzed using Chi-square and Kappa tests, considering a significance level of 5%. Results: HCI showed the highest prevalence of TMD, and the comparison between RDC/TMD, FAI, and HCI showed low agreement (k=0.17 and k=0.35 respectively). Most individuals presented mild TMD for both FAI and HCI indexes. A moderate correlation for TMD severity was obtained (kw=0.53) between FAI and HCI, and a high sensitivity and low specificity were observed for both diagnosis when compared to RDC/TMD. Conclusion: The prevalence of TMD may vary significantly depending on the index used for its diagnosis, which may lead to a large number of false positives and overtreatments. (AU)

Objetivo: Verificar o nível de concordância entre diferentes índices utilizados para avaliar a prevalência de disfunções temporomandibulares (DTMs). Material e Métodos: Cento e um estudantes de odontologia foram selecionados por um processo randomizado. As DTMs foram avaliadas pelo Índice Anamnéstico de Fonseca (IAF), pelo Índice Clínico de Helkimo (ICH) e pelo Research Diagnostic Criteria for TMD (RDC / TMD). Os dados foram analisados pelos testes Qui-quadrado e Kappa, considerando um nível de significância de 5%. Resultados: A aplicação do ICH levou a uma maior prevalência de DTM, e a comparação entre o RDC/TMD, IAF e ICH mostrou baixa concordância (k = 0,17 e k = 0,35, respectivamente). A maioria dos indivíduos apresentou DTM leve para os índices FAI e ICH. Uma correlação moderada para a gravidade da DTM foi obtida (kw = 0,53) entre FAI e HCI, e uma alta sensibilidade e baixa especificidade foram observadas para ambos os diagnósticos quando comparados com o RDC/TMD. Conclusão: A prevalência de DTM pode variar significativamente, dependendo do índice usado para o seu diagnóstico, o que pode levar a um grande número de falsos positivos e sobretratamentos. (AU)

Periodontal Conditions of Abutments and Non-Abutments in Removable Partial Dentures over 7 Years of Use.

PURPOSE: To evaluate the periodontal conditions and integrity of abutment and non-abutment teeth of patients evaluated 7 years after insertion of the removable partial denture (RPD). MATERIALS AND METHODS: Twenty-two patients (17 women, 5 men) were assessed at the moment of denture insertion and 7 years later. The following items were verified in each assessment: bleeding on probing (BP), probing depth (PD), gingival recession (GR), and mobility (M), comparing direct and indirect abutment teeth, and the teeth not involved in the denture design. Tooth integrity was also evaluated and classified as intact when no caries or fractures were observed. The Kruskal-Wallis test was used to reveal statistical significance between the groups (p = 0.05) as well as the Bonferrroni-corrected Mann-Whitney test for post hoc comparison. The Wilcoxon test was used for evaluation within the group over time. Fisher's exact test was applied to cross data about abutment integrity. RESULTS: Statistically significant differences were found for GR (baseline, p < 0.001; 7 years, p < 0.001) and PD (baseline, p = 0.001; 7 years = 0.004) between the three groups at baseline and after 7 years of follow-up. Mean BP and M values increased from initial assessment to after 7 years of RPD use in every group, but no statistically significant difference was found between the groups. For abutment integrity, a statistically significant difference (p = 0.028) was observed, and the direct abutment exhibited more (33.3%) caries and fractures. CONCLUSION: RPDs generated more periodontal damage to direct abutments, since higher gingival recession probing depth indexes, and presence of caries and fractures were observed in comparison to indirect abutments and non-abutments.

Psychosocial aspects and temporomandibular disorders in dental students.

OBJECTIVE: Dental students have high levels of anxiety that can affect not only academic performance but also increase the risk for other diseases. It is believed that the increase in the incidence of chronic orofacial pain in temporomandibular disorders (TMDs) may have an impact on the quality of life and general health of subjects. The aim of this study was to evaluate the prevalence of TMD in dental students and its association with general health, quality of life, and anxiety. METHOD AND MATERIALS: Ninety students were evaluated by four questionnaires to determine the prevalence and sever-ity of TMD (Fonseca's questionnaire) and to quantify general health (General Health Questionnaire - GHQ), quality of life (World Health Organization Quality of Life - Brief version - WHOQOL-brief) and anxiety levels (State-Trait Anxiety Index - STAI). RESULTS: Approximately 58.9% of dental students presented TMD. Among the indicators of general health, psychologic stress (P = .010), distrust in their own performance (P = .012), and psychosomatic disorders (P = .020) showed a statistically significant difference with the presence of TMD. The four areas proposed in the questionnaire regarding quality of life, such as physical (P = .016), psychologic (P < .001), social (P = .045), and environmental (P = .017) factors also showed significant differences with the presence of TMD. CONCLUSION: A high prevalence of TMD was observed in dental students. In addition, some psychologic domains are important psychosocial indicators associated with the presence of TMDs.

Does a mandibular RDP and new maxillary CD improve masticatory efficiency and quality of life in patients with a mandibular Kennedy class I arch?

OBJECTIVES: To evaluate the change in masticatory efficiency and quality of life of patients treated with mandibular Kennedy class I removable partial dentures (RPDs) and maxillary complete dentures at the Department of Dentistry of the Federal University of Rio Grande do Norte. MATERIALS AND METHODS: A total of 33 Kennedy class I patients were rehabilitated with maxillary complete dentures, and mandibular RPDs were selected for this non-randomized prospective intervention study. The patients had a mean age of 59.1 years. Masticatory efficiency was evaluated by colorimetric assay using fuchsin capsules. The measurements were conducted at baseline and 2 and 6 months after prosthesis insertion. Quality of life was evaluated using the Oral Health Impact Profile (OHIP-14) at baseline and 6 months after denture insertion. The Kolmogorov-Smirnov normality test was applied. Masticatory efficiency was evaluated by repeated measures ANOVA. Oral health-related quality of life was compared using the paired t test. RESULTS: There was no statistically significant difference in masticatory efficiency after denture insertion (p = 0.101). Significant differences were found (p = 0.010) for oral health-related quality of life. A significant improvement in psychological discomfort (p < 0.01) and psychological disability (p < 0.01) was observed. Mean difference value (95 % confidence interval) was 6.8 (3.8 to 9.7) points, reflecting a low impact of oral health on quality of life, considering the 0-56 range of variation of the OHIP-14 and a Cohen's d of 1.13. CONCLUSION: According to the results of the present study, rehabilitation with Kennedy class I RPDs and complete dentures did not influence masticatory efficiency but improved oral health-related quality of life. CLINICAL RELEVANCE: The association between the patient's quality of life and the masticatory efficiency is important for treatment predictability.

The influence of mandibular ridge anatomy on treatment outcome with conventional complete dentures.

Since prognostic indicators are likely to take on increasing importance as a diagnostic tool for selection of patients for implant provision, this study investigated the influence of the shape and resiliency of the mandibular alveolar ridge on the retention and stability of conventional complete dentures. Ninety- three edentulous patients wearing both maxillary and mandibular conventional complete dentures composed the sample. Data were collected regarding shape and resiliencyof the mandibular residual ridge. Dentures were assessed for retention and stability using an objective and reproducible tool.The associations between the clinical characteristics of the mandibular alveolar ridge and denture retention and stability were analyzed using chi-square and Fisher exact tests (a = 0.05). A significant association between ridge shape and denture stability (p < 0.05) was found, while ridge resiliency was significantly associated to denture retention (p < 0.001). Based on the results, mandibular ridge shape and resiliency influenced the retention and stability of conventional complete dentures.

Signs of Combination Syndrome and removable partial denture wearing / Sinais da Síndrome da Combinação e o uso de prótese parcial removível

Introduction: Combination Syndrome (CS) is a pathological condition observed in maxillary complete denture (CD) and mandibular removable partial denture (RPD) wearers. Purpose: The aim of this study was to observe and measure the prevalence of CS signs in treatment-seeking wearers of maxillary CD associated or not with RPD (mandibular Kennedy Class I). The association between RPD wearing and the number of CS clinical signs was also evaluated. Material and method: The sample included 62 patients seen at the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). A clinical oral examination was conducted to assess the presence of specific clinical signs of CS as described by Kelly (1972): bone resorption in the maxillary anterior region, tuberosity overgrowth, palatal papillary hyperplasia, extrusion of mandibular anterior teeth and bone resorption in the mandibular posterior region. The chi-square test at the 95% level of significance was used to test the association between dependent and independent variables. Result: Mandibular resorption was the most frequent complication (93.5%). There was a statistically significant difference between RPD wearers and non-wearers with regard to extrusion of mandibular anterior teeth (p = 0.045). Conclusion: Within the limitations of the present study, a high prevalence of CS clinical signs was observed, but no association between RPD wearing and syndrome characteristics was found. .

Introdução: A Síndrome da Combinação (SC) é uma condição patológica associada aos pacientes usuários de prótese total maxilar e prótese parcial removível (PPR) mandibular. Objetivo: Observar e mensurar a prevalência dos sinais da Síndrome da Combinação encontrados em pacientes usuários de prótese total maxilar na presença ou ausência de PPR mandibular (Classe I de Kennedy); e averiguar uma possível associação entre a utilização de PPR e a prevalência dos sinais clínicos da síndrome. Material e método: A amostra foi composta por 62 pacientes atendidos no Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN). O exame clínico intrabucal foi realizado para a verificação da presença ou ausência dos sinais clínicos específicos da Síndrome da Combinação, descrita por Kelly (1972): reabsorção óssea na região anterior da maxila, aumento das tuberosidades, hiperplasia papilar palatina, extrusão dos dentes naturais inferiores anteriores e reabsorção óssea posterior mandibular (variáveis dependentes). Para determinação da associação entre as variáveis dependentes e independentes (uso de PPR inferior e tempo de edentulismo superior), foi utilizado o teste qui-quadrado com significância de 95%. Resultado: A característica mais frequente foi a presença de reabsorção mandibular (93,5%). Quanto à associação entre o uso de PPR inferior e as características da Síndrome da Combinação, só houve diferença estatisticamente significativa entre portadores e não portadores de PPR com relação à extrusão dos dentes inferiores anteriores (p = 0,045). Conclusão: Dentro ...

The influence of mandibular ridge anatomy on treatment outcome with conventional complete dentures

Since prognostic indicators are likely to take on increasingimportance as a diagnostic tool for selection of patients forimplant provision, this study investigated the influence of theshape and resiliency of the mandibular alveolar ridge on theretention and stability of conventional complete dentures. Ninety-three edentulous patients wearing both maxillary andmandibular conventional complete dentures composed the sample.Data were collected regarding shape and resiliencyof themandibular residual ridge. Dentures were assessed for retentionand stability using an objective and reproducible tool.The associationsbetween the clinical characteristics of the mandibularalveolar ridge and denture retention and stability were analyzedusing chi-square and Fisher exact tests (α = 0.05). A significantassociation between ridge shape and denture stability (p < 0.05)was found, while ridge resiliency was significantly associated todenture retention (p < 0.001). Based on the results, mandibularridge shape and resiliency influenced the retention and stabilityof conventional complete dentures...

Effect of Watsu therapy on psychological aspects and quality of life of patients with temporomandibular disorder: case report / Efeito da terapia Watsu sobre os aspectos psicológicos e a qualidade de vida em pacientes com disfunções temporo-mandibulares: relato de caso

Watsu therapy is a water relaxation intervention technique performed individually in a warm pool with music and peaceful settings involving harmonious rotational movements, stretching, tractions on the joints and pressures at the points of muscle tension. This study evaluated the effect of Watsu therapy on psychological aspects (anxiety and minor psychiatric disorders) and on the quality of life of a patient with temporomandibular disorders. The patient answered three questionnaires: STAI (State-Trait Anxiety Inventory) and GHQ (Goldberg Health Questionnaire) to assess anxiety and psychiatric disorders respectively, and WHOQOL- Brief (World Health Organization Quality of Life) to assess quality of life. Watsu therapy has been used in patients with temporomandibular disorders (TMD) such as myofascial pain diagnosed by RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders). Psychological aspects and quality of life were assessed before and after Watsu therapy. The results after treatment showed relevant and significant improvement on all indices evaluated. Therefore, it was shown that Watsu therapy was effective in reducing anxiety and minor psychiatric disorders, as well as improved quality of life of patients with temporomandibular disorder.

A terapia Watsu é uma técnica de terapia aquática para relaxamento realizada individualmente em piscina aquecida com música em ambiente tranquilo e harmonioso, envolvendo movimentos rotacionais, alongamento, trações nas articulações e pressões em pontos de tensão muscular. Este estudo avaliou o efeito da terapia Watsu nos aspectos psicológicos (ansiedade e distúrbios psiquiátricos menores) e a qualidade de vida de uma paciente com disfunção temporo-mandibular. A paciente respondeu a três questionários: Inventário de Ansiedade - Resumido - Estado e Questionário de Saúde Geral para avaliar ansiedade e distúrbios psiquiátricos menores, respectivamente e; o Questionário de Qualidade de Vida da Organização Mundial de Saúde. A terapia Watsu foi usada em paciente com disfunção temporo-mandibular, como dor miofascial diagnosticada pelos Critérios de diagnóstico em pesquisa para Disfunção Temporo-mandibular. Os aspectos psicológicos e qualidade de vida foram avaliados antes e após a terapia Watsu. Os resultados após o tratamento mostraram melhora relevante e significativa em todos os índices avaliados. Portanto, pode-se concluir que a terapia Watsu foi eficaz na redução de ansiedade e distúrbios psiquiátricos menores, bem como melhora da qualidade de vida em paciente com disfunção temporo-mandibular.

Association between prosthetic factors and temporomandibular disorders in complete denture wearers.

OBJECTIVE: The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition. BACKGROUND: There is no consensus about the relationship between prosthetic factors and TMD among denture wearers. MATERIALS AND METHODS: The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests. RESULTS: 37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56). CONCLUSION: Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found.
