RESUMO
PURPOSE: The aim of this study is to assess the effects of respiratory exercises (inspiratory and expiratory) in individuals with sleep bruxism (SB) and associated obstructive sleep apnea (OSA). METHODS: This is a double-blind, placebo-controlled randomized clinical trial including individuals with SB and associated respiratory events in OSA. Respiratory physical therapy was performed using inspiratory (Threshold® IMT), expiratory (Threshold® PEP) muscle training, and compared with a placebo group. A total of 30 daily respiratory cycles (inspiration and expiration) were performed five times a week for 12 weeks. Individuals were reassessed at two times, at baseline (T1) and after 12 weeks of training (T2) by means of the Pittsburgh Sleep Quality Index and Polysomnography. RESULTS: Awakening was significantly different (p ≤ 0.05) between the inspiratory group and placebo 12 weeks after respiratory physical therapy. The number of contractions of the masseter muscle differed between the inspiratory, expiratory, and placebo groups (p ≤ 0.05). CONCLUSION: Respiratory physical therapy for OSA improved awaking levels in 80 and 67% of the number of masseter muscle contractions, when compared to placebo.

BACKGROUND: Obstructive sleep apnea (OSA) is a very common condition in patients with temporomandibular disorders (TMD). However, there is little evidence of a connection between them. OBJECTIVE: The aim of this systematic review and meta-analysis is to assess the association between OSA and TMD in adult population. METHODS: Case-control, cross-sectional and cohort studies on the association between TMD and OSA were searched in the EMBASE, LILACS, LIVIVO, PubMed/MEDLINE, Scopus, Web of Science, Google Scholar, Open Grey and Pro Quest databases. TMD should be assessed using Research Diagnostic Criteria (RDC/TMD) or Diagnostic Criteria (DC/TMD) and OSA using polysomnography (PSG) and/or a validated questionnaire. The risk of bias was evaluated using the Joanna Briggs Institute Critical Assessment Checklists; and an association meta-analysis was performed. The effect measure included the odds ratio (OR) in dichotomous variables and a 95% confidence interval (CI). Certainty of evidence was determined by analysing groups using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS: Out of the 1024 articles screened, 7 met the inclusion criteria for the qualitative synthesis, and 6 for quantitative analysis. All articles were classified at low risk of bias. A positive association with OSA was found in patients with TMD (OR = 2.61; 95% CI = 2.31, 2.95). A significant association was also found irrespective to the OSA diagnostic methods applied (for studies using PSG + validated questionnaires: OR = 2.74; 95% CI = 2.11, 3.57; for studies using validated questionnaires only: OR = 2.55; 95% CI = 2.22, 2.92). GRADE was moderate. CONCLUSION: Patients with TMD presented a significant association with OSA regardless of the OSA diagnostic method (PSG and/or validated questionnaires). OSA screening should be part of the TMD examination routine. Furthermore, due to the different OSA assessment methods used and the small number of studies included, there is a need to include a larger number of studies using PSG to better elucidate this association.
RESUMO
Different characteristics of bars (cross-sectional shape, diameter, distal extension etc.) lead to different biomechanical behavior (retention and stress) with implants and peri-implant tissues.Aim: To evaluate the impact of implant-supported removable prostheses bar designs in fully edentulous arch (in the maxilla and/or mandibula), with 4 implants or more, on the peri-implant soft and hard tissues.Two reviewers searched for observational studies, RCT and in vitro studies, published on five main databases and three from the grey literature, without restrictions on November 2023.Of the 3049 selected articles, four met the inclusion criteria. Four RCT evaluated peri-implant health tissues in full edentulous arches with 4 or 6 implants rehabilitated with implant bar overdentures. One prospective study with 5 years follow-up evaluated the success/survival rate of implants and implant bar overdentures. Overall, 261 subjects were enrolled in our systematic review with 1176 implants. Overdentures' survival rate was 100%. There was a trend that plaque indices and gingival indices were low in all of the studies, however no statistical analysis was done due to the lack of information.Due to the lack of information in the included studies, we cannot confirm if bar characteristics affect the peri-implant tissues health.

Abstract Objective: Lysosomal acid lipase deficiency (LAL-D) is an underdiagnosed autosomal recessive disease with onset between the first years of life and adulthood. Early diagnosis is crucial for effective therapy and long-term survival. The objective of this article is to recognize warning signs among the clinical and laboratory characteristics of LAL-D in pediatric patients through a scope review. Sources: Electronic searches in the Embase, PubMed, Livivo, LILACS, Web of Science, Scopus, Google Scholar, Open Gray, and ProQuest Dissertations and Theses databases. The dataset included observational studies with clinical and laboratory characteristics of infants, children and adolescents diagnosed with lysosomal acid lipase deficiency by enzyme activity testing or analysis of mutations in the lysosomal acid lipase gene (LIPA). The reference selection process was performed in two stages. The references were selected by two authors, and the data were extracted in June 2020. Summary of the findings: The initial search returned 1593 studies, and the final selection included 108 studies from 30 countries encompassing 206 patients, including individuals with Wolman disease and cholesteryl ester storage disease (CESD). The most prevalent manifestations in both spectra of the disease were hepatomegaly, splenomegaly, anemia, dyslipidemia, and elevated transaminases. Conclusions: Vomiting, diarrhea, jaundice, and splenomegaly may be correlated, and may serve as a starting point for investigating LAL-D. Familial lymphohistiocytosis should be part of the differential diagnosis with LAL-D, and all patients undergoing upper gastrointestinal endoscopy should be submitted to intestinal biopsy.

Abstract This study aimed to answer the following question: What is the proportion of acceptance reported by parents toward pediatric behavior guidance techniques (BGTs)? Observational studies that evaluated parental acceptance of BGTs during pediatric dental visits among parents of non-special health care need (non-SHCN) and SHCN children were included. A search of the Cochrane Library, Latin American and Caribbean Health Sciences (LILACS), MedLine/PubMed, PsycINFO, Scopus, and Web of Science databases, in addition to gray literature, was performed until October 2021. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment. The certainty of evidence was assessed using the Recommendation, Assessment, Development, and Evaluation (Grade). Fifty-three studies with 4868 participants were included, and 42 were retained for the random-effects proportion meta-analysis. The methodological quality varied from low to high. The agreement with the BGTs varied from 85.6% (95%CI: 77.5-92.1; p < 0.001; I 2 = 93.6%; 16 studies; n = 1399) for tell-show-do to 25.7% (95%CI: 17.8-34.4; p < 0.001; I 2 = 90.4%; 12 studies; n = 1129) for passive protective stabilization among non-SHCN children's parents; meanwhile, among the parents of SHCN children, it varied from 89.1% (95%CI: 56.1-99.7; p < 0.001; I 2 = 95.7%; 3 studies; n = 454) for tell-show-do to 29.1% (95%CI: 11.8-50.0; p = 0.001; I 2 = 84.8%; 3 studies; n = 263) for general anesthesia. The effect estimates varied greatly, as substantial heterogeneity across studies was observed, thus limiting the confidence in the results. Parents were more likely to agree with basic BGTs over advanced BGTs, with very low certainty of evidence. Dentists should discuss BGT options with parents.

RESUMO
ABSTRACT Objective: To identify biomarkers for Parkinson's disease, cerebrospinal fluid, blood, saliva, and urine. Method: The studies were collected from the Cochrane, LILACS, PubMed, SCOPUS, WEB OF SCIENCE, OpenGrey, ProQuest and Google Scholar databases starting from May 3, 2016 and updated on March 20, 2017. Twenty-two studies were evaluated, by the Quality Assessment Tool for Diagnostic Accuracy Studies and Review Manager 5.3. Results: Evidence shows that serum antibodies can be used as highly specific and accurate biomarkers for the diagnosis of Parkinson's disease at the outset. Biomarkers in the cerebrospinal fluid are related to increased motor severity, postural instability, gait abnormality, and cognitive impairment. Conclusion: Serum and cerebrospinal antibodies can be used as diagnostic biomarkers at the onset of the disease.

Abstract Introduction: Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. Objective: This systematic review evaluated the diagnostic validity of different methods for assessment of swallowing sounds, when compared to videofluroscopy swallowing study to detect oropharyngeal dysphagia. Methods: Articles in which the primary objective was to evaluate the accuracy of swallowing sounds were searched in five electronic databases with no language or time limitations. Accuracy measurements described in the studies were transformed to construct receiver operating characteristic curves and forest plots with the aid of Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). The methodology of the selected studies was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. Results: The final electronic search revealed 554 records, however only 3 studies met the inclusion criteria. The accuracy values (area under the curve) were 0.94 for microphone, 0.80 for doppler, and 0.60 for stethoscope. Conclusion: Based on limited evidence and low methodological quality because few studies were included, with a small sample size, from all index testes found for this systematic review, doppler showed excellent diagnostic accuracy for the discrimination of swallowing sounds, whereas microphone-reported good accuracy discrimination of swallowing sounds of dysphagic patients and stethoscope showed best screening test.
Resumo Introdução: A disfagia orofaríngea é uma comorbidade altamente prevalente em pacientes neurológicos e representa uma séria ameaça à saúde, pode levar a desfechos como pneumonia por aspiração, hospitalização e até morte. A avaliação propõe um método não invasivo, acústico, para diferenciar entre indivíduos com e sem sinais de penetração e aspiração. Objetivo: Esta revisão sistemática analisou a validade diagnóstica de diferentes métodos para avaliação dos sons de deglutição, quando comparados com a videofluoroscopia da deglutição para detectar disfagia orofaríngea. Método: Artigos nos quais o objetivo principal era avaliar a acurácia dos sons de deglutição foram pesquisados em cinco bancos de dados eletrônicos sem limitações de idioma ou tempo de publicação. As medidas de acurácia descritas nos estudos foram transformadas para construir curvas ROC (Receptor Operating Characteristic) e gráfico em floresta (forest plot) com o auxílio do software Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Dinamarca). A metodologia dos estudos selecionados foi avaliada com a ferramenta Avaliação da Qualidade de Estudos de Acurácia de Testes Diagnósticos-2. Resultados: A busca eletrônica final resultou na identificação de 554 artigos; no entanto, apenas três estudos preencheram os critérios de inclusão. Os valores de acurácia (área abaixo da curva) foram 0,94 para microfone, 0,80 para doppler e 0,60 para estetoscópio. Conclusão: Baseado nas evidências limitadas e da baixa qualidade metodológica, pois foram poucos os estudos incluídos, e com pequeno tamanho amostral, de todos os testes diagnósticos (index testes) encontrados para essa revisão sistemática o doppler mostrou excelente acurácia diagnóstica na discriminação dos sons de deglutição, o microfone demonstrou uma boa acurácia na discriminação dos sons de pacientes disfágicos e o estetoscópio revelou o melhor teste de triagem.

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 (á = 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

A systematic review was conducted to identify reliable somatosensory evaluation methods for atypical odontalgia (AO) patients. The computerized search included the main databases (MEDLINE, EMBASE, and Cochrane Library). The studies included used the following quantitative sensory testing (QST) methods: mechanical detection threshold (MDT), mechanical pain threshold (MPT) (pinprick), pressure pain threshold (PPT), dynamic mechanical allodynia with a cotton swab (DMA1) or a brush (DMA2), warm detection threshold (WDT), cold detection threshold (CDT), heat pain threshold (HPT), cold pain detection (CPT), and/or wind-up ratio (WUR). The publications meeting the inclusion criteria revealed that only mechanical allodynia tests (DMA1, DMA2, and WUR) were significantly higher and pain threshold tests to heat stimulation (HPT) were significantly lower in the affected side, compared with the contralateral side, in AO patients; however, for MDT, MPT, PPT, CDT, and WDT, the results were not significant. These data support the presence of central sensitization features, such as allodynia and temporal summation. In contrast, considerable inconsistencies between studies were found when AO patients were compared with healthy subjects. In clinical settings, the most reliable evaluation method for AO in patients with persistent idiopathic facial pain would be intraindividual assessments using HPT or mechanical allodynia tests.

BACKGROUND AND OBJECTIVES: For most cases, temporomandibular disorders should be treated by a non-invasive, interdisciplinary and integrative process. In traditional Chinese medicine, acupuncture is an excellent tool aiming at treating and healing this disease. This study was a critical literature review to observe the efficacy of traditional Chinese acupuncture to treat muscular temporomandibular disorders and to identify primary acupoints. CONTENTS: Pubmed, LILACS, Scielo and Cochrane databases were queried to identify scientific articles relevant for the study. Articles were selected from January 2000 to May 2013. A total of 125 articles were found and 21 were included. Acupuncture treatment alone or as additional therapy, or even compared to other techniques, was superior and effective to improve pain and function of patients with temporomandibular disorders and most commonly used acupoints were IG4, E6, E7 and F3. CONCLUSION: This study has shown that acupuncture is a technique recommended by national and international literature to treat muscular temporomandibular disorders, promoting pain relief and/or total intensity, improvement of joint movements and oral function and decrease of masticatory muscles hyperactivity. .

CONCLUSÃO: Este estudo demonstrou que a acupuntura é uma técnica recomendada pela literatura nacional e internacional para o tratamento de disfunções temporomandibulares de origem muscular, promovendo alivio e/ou redução total da intensidade dolorosa, melhora nos movimentos mandibulares e na função oral e diminuição da hiperatividade muscular dos músculos da mastigação. .
RESUMO
OBJECTIVES: This cross-sectional study aimed to evaluate the influence of Primary Headache (PH) on efficacy of a Temporomandibular Disorders (TMD) conservative therapy and its association with the presence of self-reported parafunctional habits. SAMPLE AND METHODS: Sample was composed of 400 medical records, divided into four groups: I) Muscular TMD (n=64); II) Muscular TMD+PH (n=48); III) Muscular TMD+Articular TMD (n=173); IV) Muscular TMD+Articular TMD+PH (n=115). All groups had undergone a TMD therapy for three months with a stabilization appliance and counseling for habits and behavioral changes, with no specific headache management. Current pain intensity and existence or not of self-reported bruxism were assessed. Repeated measures ANOVA and Chi-Square test followed by Odds were used for statistical analysis, with a significance level of 5%. RESULTS: results of this study showed that: (1) A conservative therapy with stabilization appliance and counseling for habits and behavioral changes was effective in the TMD pain relief; (2) Groups with an additional diagnosis of PH had worsened the pain improvement significantly; and (3) no association between the presence of self-reported bruxism and PH was found. CONCLUSIONS: this study could elucidate the important effect that headache may have on the TMD management. .

ABSTRACT Low pressure Pain Threshold (PPT) is considered a risk factor for Temporomandibular Disorders (TMD) and is influenced by psychological variables. Objectives To correlate deep pain sensitivity of masticatory muscles with prosthetic factors and Oral-Health-Related Quality of Life (OHRQoL) in completely edentulous subjects. Material and Methods A total of 29 complete denture wearers were recruited. The variables were: a) Pressure Pain Threshold (PPT) of the masseter and temporalis; b) retention, stability, and tooth wear of dentures; c) Vertical Dimension of Occlusion (VDO); d) Oral Health Impact Profile (OHIP) adapted to orofacial pain. The Kolmogorov-Smirnov test, the Pearson Product-Moment correlation coefficient, the Spearman Rank correlation coefficient, the Point-Biserial correlation coefficient, and the Bonferroni correction (α=1%) were applied to the data. Results The mean age (standard deviation) of the participants was of 70.1 years (9.5) and 82% of them were females. There were no significant correlations with prosthetic factors, but significant negative correlations were found between the OHIP and the PPT of the anterior temporalis (r=-0.50, 95% CI-0.73 to 0.17, p=0.005). Discussion The deep pain sensitivity of masticatory muscles in complete dentures wearers is associated with OHRQoL, but not with prosthetic factors.

A large number of disorders affecting the masticatory system can cause restriction of mouth opening. The most common conditions related to this problem are those involving the temporomandibular joint (TMJ) and the masticatory muscles, when facial pain also is an usual finding. Congenital or developmental mandibular disorders are also possible causes for mouth opening limitation, although in a very small prevalence. Coronoid process hyperplasia (CPH) is an example of these cases, characterized by an excessive coronoid process growing, where mandibular movements become limited by the impaction of this structure on the posterior portion of the zygomatic bone. This condition is rare, painless, usually bilateral and progressive, affecting mainly men. Diagnosis of CPH is made based on clinical signs of mouth opening limitation together with imaging exams, especially panoramic radiography and computerized tomography (CT). Treatment is exclusively surgical. This paper presents a case of a male patient with bilateral coronoid process hyperplasia, initially diagnosed with bilateral disk displacement without reduction, and successfully treated with intraoral coronoidectomy. It is emphasized the importance of differential diagnosis for a correct diagnosis and, consequently, effective management strategy.
Um grande número de distúrbios pode provocar limitação no grau de abertura bucal. As condições mais comuns relacionadas com esse problema são aquelas que envolvem a articulação temporomandibular (ATM) e músculos mastigatórios, em que, além da limitação, a dor facial é um achado comum. Distúrbios congênitos ou de desenvolvimento da mandíbula também são possíveis causas para limitação de abertura bucal, embora possuam uma baixa prevalência. A hiperplasia do processo coronóide (HPC) é um exemplo dessas causas, caracterizada por um desenvolvimento excessivo do processo coronóide, em que o movimento mandibular torna-se limitado pela impacção dessa mesma estrutura na parte posterior do osso zigomático. Esta condição é rara, indolor, geralmente bilateral e progressiva, afetando principalmente homens. O diagnóstico de HPC é feito por meio dos sinais clínicos de abertura bucal limitada associado com exames de imagem, especialmente a radiografia panorâmica e tomografia computadorizada (TC). O tratamento é exclusivamente cirúrgico. O objetivo desse artigo é apresentar um caso de paciente do sexo masculino com hiperplasia bilateral do processo coronóide, inicialmente diagnosticado com deslocamento de disco sem redução bilateral, e tratado com sucesso com coronoidectomia intraoral. Assim, é enfatizada a importância do diagnóstico diferencial para um correto diagnóstico e, consequentemente, estratégias efetivas de tratamento.

Odontalgia Atípica (OA) é uma condição dolorosa orofacial crônica de intensidade moderada a severa, que ocorre nas estruturas dentoalveolares e na mucosa oral. É considerada de difícil diagnóstico por estar associada com a ausência de alterações clínicas e radiográficas perceptíveis. Seus aspectos patofisiológicos sensoriais e de manutenção e perpetuação da dor ainda são mal compreendidos. Os objetivos deste estudo foram: (1) avaliar as alterações somatossensoriais em pacientes com OA através dos testes sensoriais quantitativos (QST); (2) ampliar o conhecimento disponível sobre os mecanismos de modulação da dor através do teste de controle de modulação da dor (CPM); e (3) avaliar as condições psicológicas como ansiedade e depressão, qualidade do sono e qualidade de vida através de questionários auto-aplicáveis. Um total de 50 indivíduos foram incluídos, sendo 25 sujeitos do grupo sintomático com OA (19 mulheres, 58,25 +- 12,17 anos de idade) e 25 sujeitos saudáveis do grupo controle (19 mulheres, 58,92 +- 7,39 anos)(p>0.05). Os QSTs englobaram os testes de Limiar de Detecção Mecânica (MDT), Limiar de Sensibilidade Dolorosa Mecânica (PDT), Teste Mecânico de Alodinia com cotonete (DMA1) e escova dental (DMA2), Testes de Detecção Dolorosa do tipo quente (HPD) e gelado (CPD) e o Teste de Somação Temporal (WUR). O controle de modulação da dor foi feito através do teste CPM e as avaliações psicológicas através do Inventário de Ansiedade e Depressão de Beck, o Índice de Qualidade do Sono de Pittsburg e o Questionário de Qualidade de Vida SF-36. Os QSTs foram repetidos após a aplicação de uma pomada anestésica de Benzocaína 2%. A análise estatística foi feita através dos testes t pareado, teste t e o teste não paramétrico de Mann-Whitney, considerando-se um nível de significância de 5%. Os resultados indicaram que sujeitos com OA apresentam ganho sensorial por meio de estímulos térmicos do tipo quente (HPD) e gelado (CPD) e estímulos mecânicos dinâmicos (DMA1...
Atypical Odontalgia (AO) is a chronic orofacial painful condition, which occurs in dentoalveolar structures and oral mucosa. AO is difficult to diagnose because it is associated with the absence of any clinical and radiographic alterations. Repetitive dental procedures are made, with the aim to relief pain. Sensory pathophysiological aspects and pain maintenance and perpetuation are still poorly understood. The aim of this study were: (1) evaluate somatosensory abnormalities in AO patients through quantitative sensory testing (QST), (2) evaluate mechanisms of pain modulation through the controlled pain modulation test (CPM), and (3) assess the psychological features such as anxiety, depression, sleep quality and quality of life through selfreported questionnaires. A total of 50 subjects were included, consisting of 25 subjects with symptomatic AO (19 women, 58.25 +- 12.17 years old) and 25 subjects in the control group (19 women, 58.92 +- 7.39 years old)(p>0.05). QST encompassed Mechanical Detection Threshold (MDT), Pain Detection Threshold (PDT), Dynamical Mechanical Allodynia with a cotton swab (DMA1) and with a toothbrush (DMA2), Cold Pain Detection (CPD), Heat Pain Detection (HPD) and Wind-up Ratio (WUR). Pain modulation was performed by CPM and psychological evaluations through Anxiety Inventory and Beck Depression Index, the Pittsburgh Sleep Quality and Quality of Life Questionnaire SF-36. QSTs were repeated after the administration of an anesthetic cream (2% Benzocaine). Statistical analysis was performed using the "t" test, paired t test and nonparametric Mann-Whitney test considering a significance level of 5%. Results indicated that AO subjects showed sensory gain through heat (HPD) and cold (CPD) stimuli and dynamic mechanical stimuli (DMA1, DMA2 and WUR), and sensory loss to mechanical stimuli (MDT, PDT). Moreover, CPM reduced pain intensity significantly only in the control group. A topical anesthesia showed a significant reduction...

Orofacial pain conditions can be classified into somatic, visceral or neuropathic pain. Somatic pain is triggered by a noxious stimulus generally inducted by peripheral traumas, such as dental implants surgeries (IMP). Visceral pain initiates within internal body tissues and is normally triggered by inflammation, as in inflammatory toothaches (IT). The third condition is neuropathic pain, which results from persistent injury to the peripheral nerve as in Atypical Odontalgia (AO). The aims of this study were: 1- to investigate somatosensory abnormalities, using mechanical, painful, and electrical quantitative sensory testing (QST), in somatic (IMP patients), visceral (IT) and neuropathic pain (AO); 2- to quantify how accurately QST discriminates an IT or AO diagnosis; and 3- to investigate the influence implant surgeries or pulpectomy may have on somatosensory system and sensory nerve fibers. Sixty subjects were divided in three groups: IMP (n = 20), IT (n = 20) and AO group (n = 20). A sequence of five QSTs and the Conditioned Pain Modulation Test (CPM) were performed one month and three months after dental implant surgery (IMP group) or pulpectomy (IT group). AO group was evaluated only at baseline. QST comprehended Mechanical Detection Threshold (MDT), Mechanical Pain Threshold (MPT), Dynamical Mechanical Allodynia (DMA), Current Perception Threshold (CPT) for A-beta (frequency of 2000Hz), A-delta (250Hz) and C fibers (5Hz) and Temporal Summation Test (TS). "Z" score transformation were applied to the data, and within and between groups were statistically analyzed using two-way ANOVA. In addition, the receiver operating characteristic curve analysis, diagnostic accuracy, sensitivity, specificity, likelihood ratios, and diagnostic odds ratio of QSTs were calculated (α = 5%). The findings of this study proved that: 1- loss of function for touch threshold and electrical threshold of C fibers is present in inflammatory toothache; 2- allodynia, hyperalgesia, gain of function for touch and pain thresholds and impaired pain modulation is detected in atypical odontalgia; 3- some QSTs may be used as complementary tests in the differential diagnosis of atypical odontalgia and inflammatory toothache with strong accuracy; 4- the most accurate QSTs for differential diagnosis between subjects with AO and IT were MDT, MPT and DMA where touch threshold forces > 1 g/mm2 and pain threshold forces > 10g/mm2 can be used to accurately discriminate AO from IT; and 5- no somatosensory modification is found after implant surgery and reduced electrical threshold in C fiber is found for patients with inflammatory toothache after 3 months of pulpectomy.(AU)
As dores orofaciais podem ser classificadas em dores somáticas, viscerais ou neuropáticas. A dor somática está relacionada a um estímulo nocivo evidente, geralmente associada a um trauma periférico, como por exemplo, nas cirurgias de implantes (IMP). As dores viscerais têm origem dentro dos órgãos e cavidades internas do corpo e são ativadas pela inflamação, como no exemplo da dor de dente do tipo Pulpite Aguda (PA). A terceira condição é a dor neuropática, que resulta de uma lesão persistente ao nervo periférico, como ocorre na Odontalgia Atípica (OA). Os objetivos deste estudo foram: 1- avaliar as alterações somatossensoriais, por meio do uso de Testes Sensoriais Quantitativos (TSQ) mecânicos, dolorosos e elétricos em dores somáticas (pacientes IMP), viscerais (PA) e neuropáticas (OA); 2- quantificar a acurácia dos TSQs na descriminação diagnóstica de uma PA ou OA; e 3- investigar alterações somatossensoriais e nas fibras nervosas sensoriais após cirurgia de instalação de implantes dentários ou pulpectomia. Sessenta sujeitos foram divididos em três grupos: IMP (n = 20), PA (n = 20) e OA (n = 20). Uma sequência de cinco TSQs e o teste de Controle da Modulação da Dor (CMD) foram realizados um mês e três meses após cirurgia de implantes (grupo IMP) ou pulpectomia (grupo PA). No grupo OA, os testes foram realizados somente uma vez no início do estudo. Os TSQs englobaram o Limiar de Detecção Mecânica (LDM), Limiar de Dor Mecânica (LDoM), Alodinia Mecânica Dinâmica (AMD), Limiar de Percepção de Corrente (LPC) para fibras A-beta (frequência de 2000Hz), A-delta (250Hz) e C (5 Hz), e o teste de Somação Temporal (ST). A transformação em escores de "Z" foi aplicada aos dados, e diferenças intra e inter-grupos foram analisadas usando ANOVA de medidas repetidas. Ainda, a acurácia diagnóstica dos TSQs foi medida por meio da sensibilidade, especificidade, razão de verossimilhança e razão de chances para diagnóstico (α = 5%). Os resultados deste estudo mostraram que: 1- perda da função em limiar táctil e limiar elétrico de fibras C está presente na Pulpite Aguda; 2- alodinia, hiperalgesia, ganho de função nos limiares de tato e de dor, e modulação da dor prejudicada são encontrados em pacientes com odontalgia atípica; 3- alguns TSQs podem ser usados como testes diagnósticos complementares ao diagnóstico diferencial entre PA e OA; 4- os TSQs com maior acurácia para o diagnóstico diferencial entre indivíduos com PA e OA foram LDM LDoM e AMD, onde uma força maior que 1 g/mm2 para limiar de tato e maior que 10 g/mm2 para limiar de dor podem ser usados com precisão; e 5- nenhuma alteração somatossensorial é encontrada após cirurgia de implantes e uma redução no limiar elétrico em fibras C é encontrado em pacientes com PA após 3 meses da pulpectomia.(AU)
